Abstract:

The grand challenge facing the chemical and allied industries in the twenty-first century is the transition to greener, more sustainable manufacturing processes that efficiently use raw materials, eliminate waste and avoid the use of toxic and hazardous materials. It requires a paradigm shift from traditional concepts of process efficiency, focusing on chemical yield, to one that assigns economic value to replacing fossil resources with renewable raw materials, eliminating waste and avoiding the use of toxic and/or hazardous substances. The need for a greening of chemicals manufacture is readily apparent from a consideration of the amounts of waste generated per kilogram of product (the E factors) in various segments of the chemical industry. A primary source of this waste is the use of antiquated ‘stoichiometric’ technologies and a major challenge is to develop green, catalytic alternatives. Another grand challenge for the twenty-first century, driven by the pressing need for climate change mitigation, is the transition from an unsustainable economy based on fossil resources—oil, coal and natural gas—to a sustainable one based on renewable biomass. In this context, the valorization of waste biomass, which is currently incinerated or goes to landfill, is particularly attractive. The bio-based economy involves cross-disciplinary research at the interface of biotechnology and chemical engineering, focusing on the development of green, chemo- and biocatalytic technologies for waste biomass conversion to biofuels, chemicals and bio-based materials. Biocatalysis has many benefits to offer in this respect. The catalyst is derived from renewable biomass and is biodegradable. Processes are performed under mild conditions and generally produce less waste and are more energy efficient than conventional ones. Thanks to modern advances in biotechnology ‘tailor-made’ enzymes can be economically produced on a large scale. However, for economic viability it is generally necessary to recover and re-use the enzyme and this can be achieved by immobilization, e.g. as solid cross-linked enzyme aggregates (CLEAs), enabling separation by filtration or centrifugation. A recent advance is the use of ‘smart’, magnetic CLEAs, which can be separated magnetically from reaction mixtures containing suspensions of solids; truly an example of cross-disciplinary research at the interface of physical and life sciences, which is particularly relevant to biomass conversion processes.

Abstract:

Some of the most important aspects of modeling in chemistry are discussed in detail. It is argued that the interpretive side of (quantum) chemistry is indispensable, since it gives sense to a myriad of experimental and computational results. The usefulness of some physical modeling is illustrated by the trichotomy approach in rationalizing acidity, basicity, and hydride affinities of neutral organic compounds. According to trichotomy paradigm, the simple chemical reaction of protonation and H- attachment can be decomposed into three separate sequential steps, which in turn mirror the initial-, intermediate-, and final-state effects. Ample evidence is given, which convincingly shows that the trichotomy approach has some distinct advantages in interpreting aforementioned properties that belong to the most important ones in chemistry and biochemistry.

Abstract:

It has been shown that it is possible to transform a well-stirred chemical medium into a logic gate simply by varying the chemistry’s external conditions (feed rates, lighting conditions, etc.). We extend this work, showing that the same method can be generalized to spatially extended systems. We vary the external conditions of a well-known chemical medium (a cubic autocatalytic reaction–diffusion model), so that different regions of the simulated chemistry are operating under particular conditions at particular times. In so doing, we are able to transform the initially uniform chemistry, not just into a single logic gate, but into a functionally integrated network of diverse logic gates that operate as a basic computational circuit known as a full-adder.

Abstract:

It is a privilege to act as the conference editor for this issue of Pure and Applied Chemistry (PAC) dedicated to the 12th Eurasia Conference on Chemical Sciences (EuAsC2S-12). The Eurasia Conferences on Chemical Sciences started in Bangkok in 1988 under the leadership of the founders, Bernd M. Rode (Austria), Hitoshi Ohtaki (Japan), and Ivano Bertini (Italy), together with Salag Dhabandana (Bangkok).During the preparation of the present issue of PAC, on 7 July 2012, Ivano Bertini, leading scientist in chemistry and biology, passed away. We will always remember him for his unselfish leadership and enormous contribution in paramagnetic NMR.The aim of the conferences is to foster friendship and exchange of knowledge between chemists in the Eurasian supercontinent as well as those in the Americas and Australia. While all previous conferences have been held in Asia or the Middle East, EuAsC2S-12 took place at the Hotel Corfu Chandris, on the island of Corfu, Greece, on 16-21 April 2012 with the aim of encouraging and enhancing the participation of European scientists and thus help to make them better known. EuAsC2S-12 was organized by the University of Ioannina on the Greek mainland with Emeritus Prof. Nick Hadjiliadis as Chair of the local organizing committee.The total number of participants was 450, with ca. 400 active delegates from 60 countries. The scientific program comprised 14 sessions, each of which was represented by invited speakers and further oral presentations on the following topics:- bioinorganic chemistry- pharmaceutical chemistry and drug design- organic synthesis and natural products- environmental and green chemistry- physical chemistry and spectroscopy- theoretical and computational chemistry- organometallic chemistry and catalysis- clinical biochemistry and molecular diagnostics- coordination chemistry and inorganic polymers- analytical and solution chemistry- supramolecular chemistry and nanomaterials- food chemistry- chemical education- polymer scienceThe scientific program, which was accompanied by a rich social activities program, included 9 plenary lectures, 214 oral presentations, and 190 poster presentations.The collection of 13 papers in this issue of PAC is a representation of the topics related to inorganic chemistry, covered in the lectures held during EuAsC2S-12. The papers represent a good cross-section of major themes ranging from traditional coordination chemistry, bio inorganic chemistry, supramolecular coordination chemistry, catalysis, and inorganic materials.The 13th Eurasia conference will be held in India in December 2014 with Prof. N. Jayaraman, Bangalore as head of the organizing committee.John C. PlakatourasConference Editor

Abstract:

The 19th IUPAC Conference on Physical Organic Chemistry (ICPOC-19) was held at the University of Santiago de Compostela, Santiago, Spain, 13-18 July 2008 under the local auspices of the Universities of Santiago, A Coruña, and Vigo. About 400 delegates attended ICPOC-19 from 39 countries, to participate in a scientific program comprising 11 plenary lectures, 22 invited lectures, 102 oral communications, and 224 posters.Physical organic chemistry, the study of the interrelationships between structure and reactivity in organic molecules, is a relatively young subfield of organic chemistry. At the end of the 20th century, there was a perception by some that chemists thoroughly understood organic reactivity and that there were no important problems left. This view ignores the fact that while the rigorous treatment of structure and reactivity in organic structures that is the field‚Äôs hallmark continues, physical organic chemistry has expanded to encompass other disciplines. In fact, the application of quantitative tools taken (historically) from physical chemistry to the solution of problems in mechanisms or in understanding properties has evolved to complex molecular problems, and is now being applied in studying catalysis, biochemistry, photochemistry, reactivity in the vapor phase, surface science, materials sciences, and other areas. Indeed, when considering a nice article on molecular biology, drug design, nanosystems, and catalysis, we observe that the experimental interpretation is based on a physical organic chemistry approach.This issue of Pure and Applied Chemistry contains 15 contributions corresponding to plenary and invited lectures presented at ICPOC-19: Symmetry of hydrogen bonds (C. Perrin, USA); Stabilizing reactive intermediates through site isolation (C. Copéret, France); Divalent carbon(0) compounds (G. Frenking, Germany); NMR spectroscopy and ion pairing: Measuring and understanding how ions interact (P. Pregosin, Switzerland); Photochemical routes to metal nanoparticles (J. Scaiano, Canada); Proton transfers in aromatic systems. How aromatic is the transition state? (C. Bernasconi, USA); How to predict changes in solvolysis mechanisms (H. Mayr, Germany); Kinetics and mechanism of the aminolysis of thioesters and thiocarbonates in solution (E. Castro, Chile); Understanding solvation (O. El Seoud, Brazil); Steric and electronic effects in SN2 reactions (E. Uggerud, Norway); Design of carborane molecular architectures with electronic structure computations: From endohedral and polyradical systems to multidimensional networks (J. Oliva, Spain); Mapping catalytic promiscuity in the alkaline phosphatase superfamily (F. Hollfelder, UK); DNA nucleobases properties and photoreactivity: Modeling environmental effects (L. Serrano-Andrés, Spain); Molecular organization and recognition properties of amphiphilic cyclodextrins (R. de Rossi, Argentina); Ionic liquids: Solvation ability and polarity (C. Chiappe, Italy).The conference program, as reflected both by the plenary and invited lectures as well as the oral communications, illustrates both the old and the new trends covering different research areas such as: reaction mechanisms, computational chemistry, synthetic chemistry, catalysis, gas-phase reactions, surface chemistry, molecular machines, organometallic chemistry, nanoscience, green chemistry, colloidal chemistry, supramolecular chemistry, and biochemistry. Papers presented in this issue of Pure and Applied Chemistry are representative of the different topics covered by the conference. We hope that they will serve as a stimulus for work by future generations of physical organic chemists.Luis Garcia-RioConference Editor

Abstract:

Background: Molecular organic photochemistry is concerned with the description of physical and chemical processes generated upon the absorption of photons by organic molecules. Recently, it has become an important part of many areas of science: chemistry, biology, biochemistry, medicine, biophysics, material science, analytical chemistry, among others. Many synthetic chemists are using photochemical reactions in crystals to generate different types of organic compounds since this methodology represents a green chemistry approach. Objective & Method: Chemical reactions in crystals are quite different from reactions in solution. The range of organic solid state reactions and the degree of control which could be achieved under these conditions are quite wider and subtle. Therefore, for a large number of molecular crystals, the photochemical outcome is not the expected product based on topochemical principles. To explain these experimental results, several physicochemical factors in crystal structure have been proposed such as defects, reaction cavity, dynamic preformation or photoinduced lattice instability and steric compression control. In addition, several crystal engineering strategies have been developed to bring molecules into adequate orientations with reactive groups in good proximity to synthesize complex molecules that in many cases are not available by conventional methods. Some strategies involve structural modifications like intramolecular substitution with different functional groups to modify intermolecular interactions. Other strategies involve chemical techniques such as mixed crystal formation, charge transfer complexes, ionic and organometallic interactions. Furthermore, some examples of the single crystal to single crystal transformations have also been developed showing an elegant method to achieve regio and stereoselectivity in a photochemical reaction. Conclusion: The several examples given in this review paper have shown the wide scope of photochemical reactions in organic molecular crystals. There are several advantages of carrying photochemical reaction in the solid state. Production of materials unobtainable by the traditional solution phase reactions, improved specificity, reduction of impurities, and enhancement in the yields by the reduction of side reactions. These advantages and the multidisciplinary nature of solid-state photochemistry make this discipline quite likely to develop a lot in the future.

Abstract:

The 26th International Carbohydrate Symposium (ICS 2012) took place in Madrid, Spain from 22 to 27 July 2012. One thousand delegates and accompanying persons attended the meeting from all continents. The meeting was a tremendous success, gathering both senior scientists and several hundreds of young glycoscientists. This conference is the most important one in carbohydrate chemistry and biochemistry, and the participants presented their latest contributions in the different aspects of the field. From organic synthesis to biomedicine, passing through structural aspects, molecular recognition features, materials science applications, and mechanistic biochemistry advances, among many others. From the chemical aspects, it is today evident that the glycochemistry field is alive and continuously expanding. Synthetic chemistry methods permit access to a variety of oligosaccharides, both neutral and charged, in amounts that in turn allow the study of their biochemical and biomedical properties at a level of complexity that was elusive a few years ago. Additionally, the latest advances in purification techniques together with the improvement in analytical tools permit working with pure glycoconjugates under many different experimental conditions. This multidisciplinary issue of Pure and Applied Chemistry gathers 10 representative contributions from eminent scientists working in the field. They encompass the different aspects described above. The importance of NMR techniques to unravel the conformation, dynamics, and molecular recognition features of oligosaccharides is described, as well as the importance of natural and modified saccharides as sources of new nanomaterials or molecular transporters. Organic synthesis methods together with enzymatic approaches are presented as complementary approaches to obtain saccharides and their glycomimetics, showing different properties as ligands and/or inhibitors and strikingly diverse structures. Modifications of polysaccharides to access novel biomaterials are also considered. Fundamental mechanistic aspects are described from the chemical and biochemical perspectives. Therefore, we feel that this PAC issue serves to show to the chemical community different aspects of modern carbohydrate chemistry, which is today at the cutting edge of diverse scientific disciplines and acts as a glue to bring together scientists with different expertise to tackle key problems for science and society.Jesús Jiménez-Barbero and Sonsoles Martín-Santamaría Conference Editors

Abstract:

The relationship between chemistry and biology is succinctly embodied in the often-cited statement "cells obey the laws of chemistry". In this context, it is also relevant to reflect on the opening lines of the famous paper by Watson and Crick: "We wish to suggest a structure for the salt of deoxyribose nucleic acid [DNA]. This structure has novel features which are of considerable biological interest" [Nature, April 25, 737 (1953)]. The elucidation of the structure of DNA and the understanding of its implications in the fundamental processes of life have laid the foundation for the transformation of biology into a truly molecular science. An important note of caution on the interaction between chemistry and biology has been wisely expressed by Arthur Kornberg (Nobel laureate in medicine 1959) "...chemistry and biology are two distinctive cultures and the rift between them is serious, generally unappreciated, and counterproductive" [Biochemistry26, 6888 (1987)]. Fortunately, continued developments have resulted in building highly significant bridges between chemistry and biology. Thus, the impact of genomic research has led to further erosion of the boundaries between chemistry and biology.Disciplines in science evolve over time, and new terms emerge which more adequately cover the evolutionary changes that take place in the disciplinary landscape. Today, there is an acknowledged recognition of a multidisciplinary area in which biological phenomena and biological processes are being defined in terms of detailed structural and mechanistic molecular events - this area represents the integration of chemistry and biology. The increasing role of molecular-level chemistry in biology has led to definitions such as biological chemistry or biomolecular chemistry.IUPAC is alert to new developments in all areas in which the role of chemistry is implicated. In an earlier initiative, the scope of activities of two of the IUPAC Divisions of basic chemistry (viz. organic and physical chemistry) was expanded to include the activities directed at understanding the chemical basis of biological phenomena. Furthermore, an interdivisional committee on biomolecular chemistry was established. Deliberations within this committee have resulted in the development of the IUPAC project 2005-042-1-300 on "Chemistry for Biology". The focus of this project was to organize a Symposium-in-Print that would illustrate the fundamental role of chemistry in a wide variety of biological topics. The project has been initiated by the Division of Organic and Biomolecular Chemistry and is actively supported by a number of IUPAC Divisions and standing committees. These groups have assigned representatives to the task group of the project in order to have an input into the project from their specific chemical background. Some of the task group members have contributed papers to the present Symposium-in-Print.It should be pointed out that the present Symposium-in-Print complements the contributions from several recent IUPAC-sponsored conferences such as the combined International Conference on Biodiversity (ICOB-5) and International Symposium on the Chemistry of Natural Products (ISCNP-25) in Kyoto, Japan, 2006, and the 9th Eurasia Conference on Chemical Sciences, Antalya, Turkey, 2006. Proceedings of these symposia are published in Pure and Applied Chemistry (PAC). Taken together, these contributions constitute a broad spectrum of illustrations demonstrating the role and the fundamental implications of chemistry for biology.It is a sad duty to report that Prof. Alastair I. Scott, one of the contributors to the Symposium-in-Print, passed away on 18 April 2007. Prof. Scott was Distinguished Professor of Chemistry and Biochemistry and Director, Center of Biological NMR, Texas A and M University. He was internationally held in high esteem as a scientist who built bridges between chemistry and biology with his work. Within IUPAC's Division of Organic and Biomolecular Chemistry, he played an active role in enthusiastically promoting the awareness of the relevance of chemistry for biology. Ian, as he was known to many of us, will be missed by all those who knew him. This issue of PAC is dedicated to his memory.Torbjörn NorinTask Group ChairmanUpendra PanditTask Group Member

Abstract:

By learning how to balance natural resource limitations and pollution prevention with economic growth, green chemistry will become the central science of sustainability. The elimination of persistent pollutants is vital for a sustainable civilization. To achieve this, the most important guiding concept is that the elemental composition of technology should be shifted toward the elemental composition of biochemistry. Oxidation chemistry is currently a prolific producer of persistent pollutants. Many arise from the use of chlorine, hypochlorite, or chlorine dioxide in large-scale oxidation processes. Oxidation chemistry can be greened by replacing these with catalyzed alternatives based on Nature's oxidizing agent, hydrogen peroxide. TAML® (TetraAmidoMacrocyclicLigand) iron catalysts, which were invented at Carnegie Mellon University, are widely patented and are being developed to activate H2O2 for commercial applications. TAML activators are water-soluble, easy to use, function well from neutral to basic pH, are not dominated by nonselective Fenton-like reactivity, are straightforward to synthesize, work effectively in minute concentrations, enable peroxide processes to occur at temperatures well below those of the processes targeted for replacement, and are amenable to modification for capturing novel selectivities. TAML activators are "dial-a-lifetime" catalysts: an activator can be chosen exhibiting a lifetime commensurate with the desired task.

Abstract:

The 12th International Conference on Polymers and Organic Chemistry (POC'06) was held in Okazaki, Japan, from 2-7 July 2006 and was attended by nearly 200 participants from 20 different countries. This was the second time that POC was held in Japan, the first time was in 1990 (1982, Lyon, France; 1984, Lancaster, UK; 1986, Jerusalem, Israel; 1988, Barcelona, Spain; 1990, Kyoto, Japan; 1994, Venice, Italy; 1996, Wroclaw, Poland; 1998, Maa'ale Hachamisha, Israel; 2000, Tianjin, China; 2002, San Diego, USA; 2004, Prague, Czech Republic).The aim of this series of symposia is to bring together chemists from different chemical fields to define and discuss the most recent developments in the areas of polymer-supported reagents, polymeric catalysts, polymers in medicine and biochemistry, polymers for separations, electro- and light-sensitive functional polymers, polymers for environmental protection, processes within functional polymers, and so on. Plenary lectures were provided by Profs. Yoshio Okamoto (Nagoya University, Japan) and Jean M. J. Fréchet (University of California, Berkeley, USA). Along with the plenary lectures, nine invited lectures featured recent advances in the field of polymer-based chemistry in organic synthesis by David E. Bergbreiter, Kuiling Ding, Shu Kobayashi, Yoon-Sik Lee, Helma Wennemers, Pradeep K. Dhal, Toshihide Inoue, Eiji Yashima, and Peter A. G. Cormack. These lectures, as well as 27 oral presentations of the selected papers, exhibited the strength, diversity, and novelty with which this scientific field is being practiced. In addition, there were 55 poster presentations.Ten articles contributed by the lecturers and the conference chairs of POC'06 appear in this issue of Pure and Applied Chemistry in order to provide a summary of last summer's conference.Shinichi ItsunoPOC'06 Co-chairYasuhiro UozumiPOC'06 Co-chair and Conference Editor

Abstract:

Inspired by the remarkable sophistication and complexity of natural metalloproteins, the field of protein design and engineering has traditionally sought to understand and recapitulate the design principles that underlie the interplay between metals and protein scaffolds. Yet, some recent efforts in the field demonstrate that it is possible to create new metalloproteins with structural, functional and physico-chemical properties that transcend evolutionary boundaries. This essay aims to highlight some of these efforts and draw attention to the ever-expanding scope of bioinorganic chemistry and its new connections to synthetic biology, biotechnology, supramolecular chemistry and materials engineering.

Abstract There are many greats in science history but relatively few women scientists that could be chosen as role models. This essay presents some from among contemporary contributors to chemistry, biochemistry, biology, physics, and astronomy. They had overcome barriers of discrimination, the difficulties of managing their time between research and family, and all have triumphed. They include some of the most famous, such as Isabella Karle, Christiane Nüsslein-Volhard, Anne McLaren, and Vera Rubin, and some less famous, including examples from Russia, India, and Turkey. Their presentation is based on personal encounters with them by the author; herself a scientist, wife, and mother.

Abstract:

Materials chemistry is making a fundamental impact in regenerative sciences providing many platforms for tissue development. However, there is a surprising paucity of replacements that accurately mimic the structure and function of the structural fabric of tissues or promote faithful tissue reconstruction. Methodologies in biomimetic materials chemistry have shown promise in replicating morphologies, architectures and functional building blocks of acellular mineralized tissues dentine, enamel and bone or that can be used to fully regenerate them with integrated cell populations. Biomimetic materials chemistry encompasses the two processes of crystal formation and mineralization of crystals into inorganic formations on organic templates. This review will revisit the successes of biomimetics materials chemistry in regenerative medicine, including coccolithophore simulants able to promote in vivo bone formation. In-depth knowledge of biomineralization throughout evolution informs the biomimetic materials chemist of the most effective techniques for regenerative framework construction exemplified via exploitation of liquid crystals (LCs) and complex self-organizing media. Therefore, a new innovative direction would be to create chemical environments that perform reaction–diffusion exchanges as the basis for building complex biomimetic inorganic structures. This has evolved widely in biology, as have LCs, serving as self-organizing templates in pattern formation of structural biomaterials. For instance, a study is highlighted in which artificially fabricated chiral LCs, made from bacteriophages are transformed into a faithful copy of enamel. While chemical-based strategies are highly promising at creating new biomimetic structures there are limits to the degree of complexity that can be generated. Thus, there may be good reason to implement living or artificial cells in ‘morphosynthesis’ of complex inorganic constructs. In the future, cellular construction is probably key to instruct building of ultimate biomimetic hierarchies with a totality of functions.

Abstract:

Bacterial growth in batch cultures occurs in four phases (lag, exponential/log, stationary and death phase) that differ distinctly in number of different bacteria, biochemistry and physiology. Knowledge regarding the growth phase and its kinetics is essential for bacterial research, especially in taxonomic identification and monitoring drug interactions. However, the conventional methods by which to assess microbial growth are based only on cell counting or optical density, without any insight into the biochemistry of cells or processes. Both Raman and Fourier transform infrared (FTIR) spectroscopy have shown potential to determine the chemical changes occurring between different bacterial growth phases. Here, we extend the application of spectroscopy and for the first time combine both Raman and FTIR microscopy in a multimodal approach to detect changes in the chemical compositions of bacteria within the same phase (intra-phase). We found a number of spectral markers associated with nucleic acids (IR: 964, 1082, 1215 cm−1; RS: 785, 1483 cm−1), carbohydrates (IR: 1035 cm−1; RS: 1047 cm−1) and proteins (1394 cm−1, amide II) reflecting not only inter-, but also intra-phase changes in bacterial chemistry. Principal component analysis performed simultaneously on FTIR and Raman spectra enabled a clear-cut, time-dependent discrimination between intra-lag phase bacteria probed every 30 min. This demonstrates the unique capability of multimodal vibrational spectroscopy to probe the chemistry of bacterial growth even at the intra-phase level, which is particularly important for the lag phase, where low bacterial numbers limit conventional analytical approaches.

Abstract:

Clinical chemistry analyser is a high-performance microcontroller-based photometric biochemical analyser to measure various blood biochemical parameters such as blood glucose, urea, protein, bilirubin, and so forth, and also to measure and observe enzyme growth occurred while performing the other biochemical tests such as ALT (alkaline amino transferase), amylase, AST (aspartate amino transferase), and so forth. These tests are of great significance in biochemistry and used for diagnostic purposes and classifying various disorders and diseases such as diabetes, liver malfunctioning, renal diseases, and so forth. An inexpensive clinical chemistry analyser developed by the authors is described in this paper. This is an open system in which any reagent kit available in the market can be used. The system is based on the principle of absorbance transmittance photometry. System design is based around 80C31 microcontroller with RAM, EPROM, and peripheral interface devices. The developed system incorporates light source, an optical module, interference filters of various wave lengths, peltier device for maintaining required temperature of the mixture in flow cell, peristaltic pump for sample aspiration, graphic LCD display for displaying blood parameters, patients test results and kinetic test graph, 40 columns mini thermal printer, and also 32-key keyboard for executing various functions. The lab tests conducted on the instrument include versatility of the analyzer, flexibility of the software, and treatment of sample. The prototype was tested and evaluated over 1000 blood samples successfully for seventeen blood parameters. Evaluation was carried out at Government Medical College and Hospital, the Department of Biochemistry. The test results were found to be comparable with other standard instruments.

Abstract:

We present a formal calculus, termed the chemtainer calculus , able to capture the complexity of compartmentalized reaction systems such as populations of possibly nested vesicular compartments. Compartments contain molecular cargo as well as surface markers in the form of DNA single strands. These markers serve as compartment addresses and allow for their targeted transport and fusion, thereby enabling reactions of previously separated chemicals. The overall system organization allows for the set-up of programmable chemistry in microfluidic or other automated environments. We introduce a simple sequential programming language whose instructions are motivated by state-of-the-art microfluidic technology. Our approach integrates electronic control, chemical computing and material production in a unified formal framework that is able to mimic the integrated computational and constructive capabilities of the subcellular matrix. We provide a non-deterministic semantics of our programming language that enables us to analytically derive the computational and constructive power of our machinery. This semantics is used to derive the sets of all constructable chemicals and supermolecular structures that emerge from different underlying instruction sets. Because our proofs are constructive, they can be used to automatically infer control programs for the construction of target structures from a limited set of resource molecules. Finally, we present an example of our framework from the area of oligosaccharide synthesis.

Abstract:

Electrospun technology is a simple and flexible method for preparation of nanofiber materials with unique physical and chemical properties. The nanofiber diameter is adjustable from several nanometers to few microns during the preparation. Electrospun nanofiber materials are easy to be assembled into different shapes of three-dimensional structures. These materials exhibit high porosity and surface area and can simulate the network structures of collagen fibers in a natural extracellular matrix, thereby providing a growth microenvironment for tissue cells. Electrospun nanofibers therefore have extensive application prospects in the biomedicine field, including in aerospace, filtration, biomedical applications, and biotechnology. Nanotechnology has the potential to revolutionize many fields, such as surface microscopy, silicon fabrication, biochemistry, molecular biology, physical chemistry, and computational engineering, while the advent of nanofibers has increased the understanding of nanotechnology among academia, industry, and the general public. This paper mainly introduces the application of nanofiber materials in tissue engineering, drug release, wound dressing, and other biomedicine fields.

Abstract:

The Cambridge Structural Database (CSD) and its associated software systems have formed the basis for more than 800 research applications in structural chemistry, crystallography and the life sciences. Relevant references, dating from the mid-1970s, and brief synopses of these papers are collected in a database, DBUse, which is freely available via the CCDC website. This database has been used to review research applications of the CSD in organic chemistry, including supramolecular applications, and in organic crystal chemistry. The review concentrates on applications that have been published since 1990 and covers a wide range of topics, including structure correlation, conformational analysis, hydrogen bonding and other intermolecular interactions, studies of crystal packing, extended structural motifs, crystal engineering and polymorphism, and crystal structure prediction. Applications of CSD information in studies of crystal structure precision, the determination of crystal structures from powder diffraction data, together with applications in chemical informatics, are also discussed.
