Abstract:
"Creativity is the soul of a nation and an inexhaustible source of a country's prosperity." Original innovation, as the major source of new technologies, will not only bring about technological breakthroughs, but give rise to new industries and new economic structures, offering unlimited opportunities for later starters to overtake the frontrunners. "Innovation in Chemistry" is the specific theme for the 40th International Union of Pure and Applied Chemistry (IUPAC) Congress, which was held on 14-19 August 2005 in Beijing, China. The Congress provided an excellent forum for presenting the latest innovative achievements in the chemical sciences and in the practice of chemistry.A total of 1083 participants from 64 countries attended the Congress. With 412 of the participants from mainland China and 556 from other countries and regions, the Congress helped to build a bridge between Chinese chemists and the world, encouraging cooperation and excellence in fundamental research and industrializations.The high-scientific value of the Congress was evident in the plenary lectures, which were delivered by eight distinguished chemists, including three Nobel Laureates and one Einstein Award Winner. A total of 1145 papers and 622 posters were presented in the eight sessions of the Congress: (1) Environmental Chemistry and Green Chemistry; (2) Chemistry in the Life Sciences and Chemical Biology; (3) Materials Chemistry, Supermolecular Chemistry, and Nanochemistry; (4) Information Technology in Chemistry and Computational Chemistry; (5) Innovation in Physical Chemistry and Biophysical Chemistry: Research Methods and Techniques; (6) Innovation in Methodology, Technique, and Instrumentation and Analytical Chemistry; (7) Innovation in Chemical Education and Teaching Methods; (8) Innovation in the Chemical and Petrochemical Industries and "Responsible Care" for Society.Fourteen papers selected from the plenary and invited lectures from the 40th IUPAC Congress are published in this special issue of Pure and Applied Chemistry (PAC), which cover a spectrum from theoretical chemistry to chemical engineering, from micro/nanoscale studies to industrial-scale process/equipment evaluations. The review on the study of single molecules and their assembly provides a comprehensive, up-to-date summary of the field based on the fundamental research; much of the information presented falls within the special expertise of the group. The paper on the superheavy element describes the latest developments in a field that has shown higher activity in recent years as the predicted "island of stability" comes within the reach of the available hardware. This area is always of special interest to international scientists owing to the special synthesis techniques for superheavy elements employed by the Dubna group. Green chemistry is becoming a characteristic area in China that plays a significant role in motivating the development of new synthetic techniques, such as cross-dehydrogenative coupling. Other papers in this issue address a variety of topics from novel instrumentation for electrochemical impedance spectroscopy to synthesis of oxide nanomaterials; from catalysts to waste water treatment. These papers give a snapshot of the research reported at the 40th IUPAC Congress. I sincerely hope that this special issue of PAC brings some fresh ideas, novel concepts, and useful data to the readers.The International Organizing Committee contributed to the shaping of an important area of emerging science and technology. Thanks and appreciations are due to the Local Organizing Committee for the efficiency and excellence of the local arrangements and for the gracious hospitality. I am grateful to those who contributed their latest research work to this issue, and the support from Dr. John W. Jost, IUPAC Executive Director.Chunli BaiPresident of the 40th IUPAC Congress,President of the Chinese Chemical Society,and Executive Vice President of the Chinese Academy of Sciences

Abstract:
In this paper the authors propose an approach for analogical modeling and numerical simulation of the phenomena of sintering, taking into account different cases depending on the type of energy used in the process of aggregation and the nature of the material powder, using a software which simulates the propagation and the control of the temperature. Many physical phenomena encountered in science and engineering can be described mathematically through partial differential equations (PDE) and ordinary differential equations (ODE) such as propagation phenomena, engineering applications, hydrotechnics, chemistry, pollution a.s.o. There may be situations when the exact establish of the analytical solutions becomes difficult or impossible for arbitrary shapes. In these cases the determination of some approximant solution through experimental methods, that have to verify with acceptable errors, the PDE expression specified to the studied phenomenon, is justified.

Abstract:

Over recent years, Ion Mobility–Mass Spectrometry (IMS–MS) measurements have become a widely used tool in a number of disciplines of scientific relevance, including, in particular, the structural characterization of mass-selected biomolecules such as proteins, peptides, or lipids, brought into the gas-phase using a variety of ionization methods. In these structural studies, the measured electrical mobilities are customarily interpreted in terms of a collision cross-section, based on the classic kinetic theory of ion mobility. For ideal ions interacting as smooth, rigid-elastic hard-spheres with also-spherical gas molecules, this collision cross-section (CCS) is identical to the true, geometric cross section. On the other hand, for real ions with non-perfectly spherical geometries and atomically-rough surfaces, subject to long-range interactions with the gas molecules, the expression for the CCS can become fairly intricate.

This complexity has frequently led to the use of helium as the drift gas of choice for structural studies, given its small size and mass, its low polarizability (minimizing long-range interactions), and its sphericity and lack of internal degrees of freedom, all of which contribute to reduce departures between measured and true cross-sections. Recently, however, a growing interest has arisen for using moderately-polarizable gases such as air, nitrogen, or carbon dioxide (among others) in these structural studies, due to a number of advantages they present over helium, including their higher breakdown voltages (allowing for higher instrument resolutions) and better pumping characteristics. This shift has, nevertheless, remained objectionable in the eye of those seeking to infer accurate structural information from ion mobility measurements and, accordingly, there is a critical need to study whether or not measurements carried out in such gases may be corrected for the finite size of the gas molecules and their long-range interactions with the ions, in order to provide cross-sections truly representative of ion geometry. A first step to address this matter is undertaken here for the special case of nearly-spherical, nanometer-sized ions.

In order to attain this goal, we have performed careful and accurate IMS–MS measurements of hundreds of electrospray-generated nanodrops of the ionic liquid (IL) 1-ethyl-3-methylimidazolium tetrafluoroborate (EMI-BF 4), in a variety of drift gases (air, CO2, and argon), covering a wide range of temperatures (20-100 °C, for both air and CO2), and considering nanodrops of both positive and negative polarity (the latter in room-temperature air only). Thanks to the combined measurement of the mass and mobility of these nanodrops, we are able to simultaneously determine a mobility-based collision cross-section and a mass-based diameter (taking into account the finite compressibility of the IL matter) for each of them, which then allows us to establish a comparison between the two.

Over the entire range of experimental conditions investigated, our measurements show that the electrical mobilities of these nearly-spherical, multiply-charged IL nanodrops are accurately described by an adapted version of the well-known Stokes—Millikan (SM) law for the mobility of spherical ions, with the nanodrop diameter augmented by an effective gas-molecule collision diameter, and including a correction factor to account for the effect of ion—induced dipole (polarization) interactions, which result in the mobility decreasing linearly with the ratio between the polarization and thermal energies of the ion–neutral system at contact. The availability of this empirically-validated relation enables us, in turn, to determine true, geometric cross-sections for globular ions from IMS—MS measurements performed in gases other than helium, including molecular or atomic gases with moderate polarizabilities. In addition, the observed dependence of the experimentally-determined values for the effective gas-molecule collision diameter and the parameters involved in the polarization correction on drift-gas nature, temperature, and nanodrop polarity, is further evaluated in the light of the results of numerical calculations of the electrical mobilities, in the free-molecule regime, of spherical ions subject to different types of scattering with the gas molecules and interacting with the latter under an ion–induced dipole potential. Among the number of findings derived from this analysis, a particularly notable one is that nanodrop–neutral scattering seems to be of a diffuse (cf. elastic and specular) character in all the scenarios investigated, including the case of the monatomic argon, which therefore suggests that the atomic-level surface roughness of our nanodrops and/or the proximity between their internal degrees of freedom, rather than the sphericity (or lack of it) and the absence (or presence) of internal degrees of freedom in the gas molecules, are what chiefly determine the nature of the scattering process.

Abstract:
The dissociative chemisorption of oxygen and water on Fe, Ti, and adlayers of each metal on the other have been explored via surface electron spectroscopies. Auger Electron Spectroscopy (AES) and X-ray Photoelectron Spectroscopy (XPS) have been used to monitor the reactions of titanium and iron with low exposures (from one to several hundred langmuirs) of oxygen and/or water vapor. Comparisons and contrasts are drawn between bulk metals and adlayer alloys--alloys formed by vapor depositing a few angstroms of one metal on top of a relatively thick film of the other metal. Most notable is the ability of a very thin layer of titanium to lessen the reactivity of a thick iron film toward oxygen.

Abstract:
Increasing the efficiency and durability of organic light-emitting diodes (OLEDs) has attracted attention recently due to their prospective wide-spread use as flat-panel displays. The performance and efficiency of OLEDs is understood to be critically dependent on the quality of the device heterojunctions, and on matching the ionization potentials (IP) and the electron affinities (EA) of the luminescent material (LM) with those of the hole (HTA) and electron (ETA) transport agents, respectively. The color and bandwidth of OLED emission color is thought to reflect the packing of the molecules in the luminescent layer. Finally, materials stability under OLED operating conditions is a significant concern. LM, HTA, and ETA thin films were grown in ultra-high vacuum using the molecular beam epitaxy technique. Thin film structure was determined in situ using reflection high energy electron diffraction (RHEED) and ex situ using UV-Vis spectroscopy. LM, HTA, and ETA occupied frontier orbitals (IP) were characterized by ultraviolet photoelectron spectroscopy (UPS), and their unoccupied frontier orbitals (EA) estimated from UV-Vis and fluorescence spectroscopies in combination with the UPS results. The stability of the molecules toward vacuum deposition was verified by compositional analysis of thin film X-ray photoelectron spectra. The stability of these materials toward redox processes was evaluated by cyclic voltammetry in nonaqueous media. Electrochemical data provide a more accurate estimation of the EA since the energetics for addition of an electron to a neutral molecule can be probed directly. The energetic barriers to charge injection into each layer of the device has been correlated to OLED turn-on voltage, indicating that these measurements may be used to screen potential combinations of materials for OLEDs. The chemical reversibility of LM voltammetry appears to limit the performance and lifetimes of solid-state OLEDs due to degradation of the organic layers. The role of oxygen as an electron trap in OLEDs has also been verified electrochemically. Finally, a more accurate determination of the offset of the occupied energy levels at the interface between two organic layers has been achieved via in situ monitoring of the UPS spectrum during heterojunction formation.

Full text
Abstract:
The use of ion-selective field-effect transistors (ISFETs) as potentiometric microsensors was investigated. In the first stage, an instrument was designed and built to operate an array of ISFETs. A microcomputer was used for instrument control and acquisition of data.
The second phase of research focussed on the development of a pH sensitive radiotelemetric device that could eventually be used for the noninvasive monitoring of gastric pH. The first attempt used an ISFET as a variable resistor in a simple telemetry circuit. The drift in the pH dependent signal from this device was significant. The use of a differential sensor was studied as a possible way to minimize the effect of signal drift. This system measured the differential output of a pH ISFET and a pH insensitive ISFET. The pH insensitivity was due to an alkanethiol monolayer at the ISFET$ vert$solution interface.
It was shown that ISFETs are well suited for use as sensors in telemetry devices. The union of these previously independent research areas has been achieved.

Abstract:
The presented study investigated the Induced Density of Interface States (IDIS) model at different polymer interfaces by using photoemission spectroscopy in combination with electrospray deposition. In recent years, organic electronics have attracted considerable attention due to their advantages of low-cost and easy-fabrication. The performance of such devices crucially depends on the energy barrier that controls the interface charge transfer. A significant effort has been made to explore the mechanisms that determine the direction and magnitude of charge transfer barriers in these devices. As a result of this effort, the IDIS model was developed to predict the energy alignment at metal/organic and organic/organic interfaces. The validity of the IDIS model on molecular interfaces was confirmed by the results of a series of experiments with small molecular materials, which are in good agreement with the theoretical calculations from the IDIS model. The charge neutrality level (CNL) and screening factor for various organic materials can be determined from the linear correlation between the hole injection barrier at metal/organic interface and the work function of its corresponding metal substrate, which stands as one of the most important features of the IDIS model. The study presented here explores whether the IDIS model is also valid for polymer interfaces. Two prototypical polymer materials: poly(3-hexylthiophene) (P3HT) and poly[2-methoxy-5-(2'-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV) were selected for the investigation. In the first part of this study, a series of metal/polymer interfaces were prepared using electrospray and investigated with photoemission spectroscopy. The linear relationship between the hole barriers extracted from the metal/polymer interface and the work function of its respective metal substrate suggests that the IDIS model is also valid for metal/polymer interfaces. The CNLs and the screening factors of P3HT and MEH-PPV are determined respectively. The experiment results are also discussed with regard to the Integer Charge Transfer (ICT) model. The comparison between the two models suggests that the IDIS model should be applied to interfaces prepared in vacuum while the ICT model works on interfaces with an ambient contamination layer present. The second part of the dissertation discusses the photoemission results of the MEH-PPV/P3HT heterojunction from the perspectives of the two models. The results indicate that the IDIS model is valid for polymer/polymer heterojunctions. The IDIS model more accurately predicted the measured orbital line up by using its principles for organic/organic heterojunction than the ICT model.

Abstract:
A common issue in Nuclear Power Plants (NPP) is the release of corrosion products from the steam generator tubes in primary circuit which gives rise, after their neutronic activation, to a residual activity very problematic during chemistry transients. The objectives of this work are not to solve directly this problem but rather to improve the understanding of this phenomenon by determining experimentally the kinetics of oxidation and metallic cations release of nickel base alloys. These results will contribute to progress in the building of a physical mechanism. The specificity of the test facility is (i) the on-line measurements of cation release rate by a highly sensitive analytical device and (ii) the in-situ measurement of oxidation rate by Diffuse Reflectance Spectroscopy (DRS). The primary water chemistry is controlled by means of a circulating micro-loop in titanium to avoid any interference with the test samples. A specific test vena is connected between the titanium micro-loop and the analytical device for on-line measurements. Metallic cation release from SG tube-samples is deduced from the measurement of nickel and iron concentrations in upstream the test vena by use of differential polarography and ICP-AES techniques. The precision on the determination of Ni and Fe concentrations is assumed to be a few tens of ppt. Oxidation or corrosion measurements are performed off-line by optical diffuse reflectance measurements specifically developed in this framework. The corrosion sample is mounted in a High Temperature and Pressure (HT-HP) spectroscopic flow-through cell connected to the test vena and fed with the primary chemistry from the titanium micro-loop. Analysis of reflection spectra provides the thickness of oxide layer. A set of parameters such as (i) temperature, (ii) hydrogen content and (iii) metallurgical surface state in nominal primary chemistry for test durations of 1500–2000 hours is planned to be investigated in the frame of metallic cation release and oxidation kinetics measurements of Ni base alloys. The aim of this paper is focused on the presentation of the online technique specifically developed in the French Technical Centre of AREVA NP to determine the metallic cation release and oxidation kinetic of Ni base alloys in primary water chemistry. First results of cation release and oxidation rate are given for shorter duration test.

Abstract:
Abstract Elemental mercury and several mercury compounds occur naturally in geologic hydrocarbons including petroleum and gas condensates. Recent advances in analytical chemistry are assisting our understanding of the chemistry of mercury in petroleum and its fate in petrochemical processes. Analytical techniques now are capable of measuring the concentration of mercury and mercury compounds in most hydrocarbon matrices to better than 1 part in 1010. A recently developed model proposes that the mean amount of mercury in crude oil is no more than 10 ppb. The various chemical forms of mercury exhibit significantly different chemical and physical behavior and thus partition to fuels, products and effluents in a complex fashion. Speciation of compounds and accurate determination of species concentrations assists accounting for mercury in petrochemical processes and prediction of the magnitude of its occurrence in water and air emissions. From knowledge of the solubilities and partition factors of the mercury compounds in petroleum, one can predict concentrations in separations and distillations. The developing understanding of mercury concentrations in crude oil suggest that mercury discharges to the environment from petroleum are small as compared to those that originate from coal combustion. Although it is generally recognized that reductions in anthropomorphic mercury emissions are beneficial to reducing mercury in the global cycle, the strategies to achieve this goal should be carefully constructed and based on the known amounts of mercury in industrial emissions. Regulations, both existing and anticipated, are major factors driving the development of mercury sequestration strategies. Emissions of mercury from petroleum production and processing are regulated by water, sediment and air criteria that are based on estimates of mercury concentrations in liquid fuels that may be in error by at least an order of magnitude. Aside from environmental concerns, mercury also is problematic to both gas processors and refiners from the standpoint of operations. The issues relate to catalyst poisoning, health and safety and occasionally precipitation/condensation of mercury in cryogenic processes. Although mercury removal systems are applied to gas and gas liquids processing, such systems are ineffective for application to crude oil.

Abstract:
The LMFBRs (Liquid Metal Cooled Fast Breading Reactors) is a key technology for the future electricity demand. Therefore, the establishment of safety of LMFBRs is deeply desired. To evaluate the safety of LMFBR steam generators, empirical studies have been performed for the ruptures of heat transfer tube caused by the overheat due to sodium-water reaction in case of a practical scale conditions. But few systematical experiments have been performed for the clarification of phenomena from the viewpoint of thermal hydraulics and physical chemistry. The absence of such studies is derived from the fact that sodium is chemically active and is not feasible for visualized experiments. To evaluate the safety against the secondary failure of heat transfer tubes by an analytical code, which has been tried in JAEA, it is required to understand the heat transfer phenomena around the tube. In this study, we investigated experimentally the thermal hydraulics behavior around a single heated rod with sodium-water reaction as an essential study for the clarification of raptures phenomena of heat transfer tube. The experimental apparatus was consisted of a sodium pool tank, an electrically heated test rod, a gas jet nozzle of argon-water mixture. We set horizontally in the sodium pool the test rod that is heated with the constant heat flux, and to which a gas jet of argon-water mixture was supplied for the sodium-water reaction from its lower side. The temperature of sodium pool was kept to be 420K so that a product of sodium-water reaction, NaOH (melting point is 591K), may exist as a solid phase. Gas jet velocity was set to be 17.3m/s, and the amount of water vapor in the gas mixture was 3% in mass. Just after the introduction of gas mixture, the temperature of sodium pool increased by the heat of chemical reaction. At the same time, the heat transfer to the rod surface decreased rapidly. By the observation after the experiment, it was confirmed that coarse reaction products deposited thickly at the upper side of the rod and finely granular products adhered to the lower ones. Thus, at low-sodium temperature conditions, the products of sodium-water reaction on the rod surface cause the decrease of heat transfer rate between the rod and sodium pool, which depends on the local distribution of deposits. The present authors therefore obtained experimentally the phenomena important for the development of an analytical code of JAEA.
