Abstract:
The effect of different factors, such as carbon fiber content, temperature, electrifying time and frequency, power density on the electrothermal properties of the composite papers with different carbon fiber content was researched. The results show that the resistivity of the composite papers decreases with the increasing of carbon fibers. The current-voltage relationship is in good conformity with the Ohm's law. The negative temperature coefficient and good reversibility are shown during the heated and cooled process of the papers. The resistance of the papers decreases gradually with electrifying time and trends to stable after several hours. On-off electrifying times on its resistance have little effect in the long term. The curve of power density and surface temperature shows a good linear behavior.

Abstract:
The influences of the oxidative modification, coupling treatment and dispersing agent for carbon fiber dispersion and binding properties were investigated, and the relationships of different ratio of carbon fiber with the physical strength and electrical conductivity of the paper were analyzed. Meanwhile fiber surface morphology, zeta potential and absorbance slurry were tested. The result showed that: coupling modification significantly improved the dispersion performance of carbon fiber, superior than oxidative modification, the increase of the dispersion would enhance the conductivity of carbon fiber network, the effect of CPAM was best in four kinds of surface-active agent, and 30% content of carbon fiber achieved the "percolation threshold” of conductive material.

Full text
Abstract:
We propose a unique soft actuator—a paper actuator—based on carbon-nanotube-composite paper (CNT-composite paper), which is a composite of carbon nanotubes (CNTs) and paper. CNT-composite paper has highly efficient properties because of the contained CNTs, such as high electrical conductivity and semiconducting properties. We are considering using CNT-composite paper for various devices. In this study, we successfully developed a paper actuator. We determined the structure of the paper actuator by referencing that of bucky-gel actuators. The actuator operates using the force generated by the movement of ions. In addition to making the paper actuator, we also attempted to improve its performance, using pressure as an index and an electronic scale to measure the pressure. We investigated the optimal dispersant for use in paper actuators, expecting the residual dispersant on the CNT-composite paper to affect the performance differently depending on the type of dispersant. Referring to research on bucky-gel actuators, we also found that the addition of carbon powder to the electrode layers is effective in improving the pressure for paper actuators. We believe that the paper actuator could be used in various situations due to its ease of processing.

Full text
Abstract:
This paper aimed to illustrate how short-term carbon futures speculators might use short-term carbon emission futures data to predict and forecast carbon prices. The paper became apposite given ubiquitous research focussing on long-term carbon futures data, which has left out short-term carbon emission futures speculators with information. Therefore, this paper demonstrated that short-term speculators in carbon futures could indeed use short-term time series data on carbon futures to make a reliable prediction and forecasting of carbon emissions futures price volatility within a short term and thus decide on investment opportunity. The sample data results showed that short-term data could produce a dependable in-sample futures prediction since the in-sample prediction fell within the 95% confidence interval. The demonstration also showed that short-term carbon futures data could assist speculators to conduct a reliable short-term out of sample forecast of carbon futures prices within the closer period. The paper offers practical assistance to carbon futures speculators and is equally important for academic studies for business and economic students on discussions and research bordering on carbon emissions, carbon trading, environmental economics and sustainable development. More carbon short-term forecasting is encouraged – such research should compare short-term forecasting of carbon futures amongst different carbon markets.

Abstract:
We have developed a unique “paper transistor” comprised of carbon nanotube (CNT) composite papers. CNTs have recently attracted much research attention in the nanotechnology field due to their many excellent physical properties, including good electrical and heat conductivities, physical strength, and dual semiconducting- and metallic- characteristics. CNTs have great potential for use as many different functional materials. In a previous work, we developed a CNT-composite paper as a new functional material. A normal paper is flexible and can be fabricated and used easily, and we can easily fabricate the CNT-composite paper by mixing pulp with CNTs. The resulting CNT-composite paper has both CNT and normal paper characteristics. In this study, we focused primarily on the dual semiconducting- and metallic- characteristics exhibited by CNTs because we can create paper composites that are both semiconducting and metallic. Our main goal was to develop a field-effect-transistor (FET) using semiconducting- and metallic- CNT-composite papers. A conventional FET has metal, insulator, and semiconductor layers. Our FET also has three layers: the metallic CNT-composite paper is used for gate, source, and drain electrodes as the metal layer; the semiconducting CNT-composite paper is used for a semiconductor as the channel layer; and the normal paper is used as a gate insulator layer. The key point here is that we were able to design and develop an FET using only normal paper and two kinds of CNT-composite paper, without any silicon or semiconductors. After the construction, we measured the electrical conductivity of our FET to test its operation. A drain-to-source current of about 10μA was observed. Moreover, we could control the current flow by controlling the gate voltage. These results demonstrate that it is possible to fabricate a paper FET using only normal paper and two kinds of CNT-composite paper.

Abstract:
Indiana University-Purdue University Indianapolis (IUPUI)<br>The prevalent applications of energy storage devices have incited wide-spread efforts on production of thin, flexible, and light-weight lithium-ion batteries. In this work, lithium-ion batteries using novel flexible paper-based current collectors have been developed. The paper-based current collectors were fabricated from carbon nanotube (CNT)-coated wood microfibers (CNT-microfiber paper). This thesis presents the fabrication of the CNT-microfiber paper using wood microfibers, coating electrode materials, design and assemblies of battery, testing methodologies, and experimental results and analyses. Wood microfibers were coated with carbon nanotubes and poly(3,4-ethylenedioxythiophene) (PEDOT) through an electrostatic layer-by-layer nanoassembely process and formed into a sheet, CNT-microfiber paper. The CNT loading of the fabricated paper was measured 10.1 μg/cm2 subsequently considered. Electrode material solutions were spray-coated on the CNT-microfiber paper to produce electrodes for the half and full-cell devices. The CNT current collector consists of a network structure of cellulose microfibers at the micro-scale, with micro-pores filled with the applied conductive electrode materials reducing the overall internal resistance for the cell. A bending test revealed that the paper-based electrodes, compared to metal ones, incurred fewer damages after 20 bends at an angle of 300o. The surface fractures on the paper-based electrodes were shallow and contained than metallic-based electrodes. The micro-pores in CNT-microfiber paper structure provides better adherence to the active material layer to the substrate and inhibits detachment while bending. Half-cells and full-cells using lithium cobalt oxide (LCO), lithium titanium oxide (LTO), and lithium magnesium oxide (LMO) were fabricated and tested. Coin cell assembly and liquid electrolyte was used. The capacities of half-cells were measured 150 mAh/g with LCO, 158 mAh/g with LTO, and 130 mAh/g with LMO. The capacity of the LTO/LCO full-cell also was measured 126 mAh/g at C/5 rate. The columbic efficiency of the LTO/LCO full-cell was measured 84% for the first charging cycle that increased to 96% after second cycle. The self-discharge test of the full-cell after charging to 2.7 V at C/5 current rate is showed a stable 2 V after 90 hours. The capacities of the developed batteries at lower currents are comparable to the metallic electrode-based devices, however, the capacities were observed to drop at higher currents. This makes the developed paper-based batteries more suitable for low current applications, such as, RFID tags, flexible electronics, bioassays, and displays. The capacities of the batteries at higher current can be improved by enhancing the conductivity of the fibers, which is identified as the future work. Furthermore, fabrication of an all solid state battery using solid electrolyte is also identified as the future work of this project.

Abstract:
This bibliographic material is patrimony of our Laboratory of the Behavior Physiology. This research unit originated in 1972 by will of Aldo Giachetti (until 1990) and with the beginning of the activity of Corrado Bucherelli. In the early 1980s, with Carlo Ambrogi Lorenzini (until 2004), the cataloging became more capillary and systematic, to continue to this day. All the researchers who worked in our laboratory contributed to this collection (Giovanna Tassoni 1986-2000, Benedetto Sacchetti 1996-2002 and Elisabetta Baldi from 1991). The study of learning, memory and behavior requires to follow a broad spectrum of neuroscience topics, ranging from neuronal biochemistry to neuropsychology. The Authors’ idea of publishing this collection comes from believing that a such website, though not exhaustive, might be a useful and targeted tool for the selection of bibliographic material in the field of behavioral neuroscience. The bibliographic references present at the publication (29500), accompanied by a brief comment highlighting the contents, are organized in relation to the topics (represented by the 99 themes) constituting the publication itself. The intersection of several references will point out the topics that represent them simultaneously. Concerning neurotransmitters and neuromodulators, references to agonists, antagonists or molecules interfering with the activity of these synapses have been inserted in the pages of the implicated neurotransmitter (e.g. acetylcholine). The pages including topics that could have been dealt with separately (e.g. active and passive avoidance) are introduced by a short explanatory note. The comment of each publication highlights the animal species used. Each comment is intended to indicate the content rather than the experimental results of paper. This choice comes from wanting to provide the reader with a more objective and less speculative comment.

Abstract:
The Inter-governmental Panel on Climate Change (IPCC) indicates that meeting the Paris Agreement's goal of limiting the global temperature rise from pre-industrial levels to between 1.5 and 2 degrees Celsius requires reaching net-zero emissions of carbon dioxide (CO2) between 2050 and 2070, as well as deep reductions in the emissions of other greenhouse gases by around mid-century (GHGs) (IPCC, 2018). At the same time countries need to build resilience to face the changes that cannot be avoided. NDC Invest was created as the one-stop-shop of the IDB Group providing technical and financial support for countries in Latin American and Caribbean (LAC) in their efforts to achieve the climate objectives under the Paris Agreement, seeking to transition to a net zero, resilient and sustainable development pathways that improve quality of life and prosperity in LAC. Through our research and experience supporting countries and piloting solutions we have developed a toolbox for support. This paper describes three NDC Invest products to support Governments to tackle challenges and scale up action towards a climate aligned and sustainable development path: i) the design of Long-Term Strategies (LTS) for net-zero emissions and resilience; ii) design of ambitious Nationally Determined Contributions (NDCs), aligned to LTS; and iii) design of investment plans and finance strategies. Our three products are not a fix recipe, but rather a toolbox to provide flexible and relevant solutions tailored to country needs and context, and different stages of design and implementation of their climate targets.

Abstract:
This article appears in theOxford Handbook of New Audiovisual Aestheticsedited by John Richardson, Claudia Gorbman, and Carol Vernallis. This chapter explores concepts of interactivity as they relate to sound production in video games. A guiding assumption of the chapter is that interactivity is a definitive paper of new digital aesthetics in general and gaming in particular. And yet, the question of interactivity has not been addressed with sufficient stringency in scholarly research. At the heart of the chapter are these questions: What makes interactive sound different from noninteractive sound? Where doesinteracting withsound fit into our understanding of our experience of sound and music in media? How do we begin to approach interactive sound from a theoretical perspective? The implications of interactivity are examined, specifically the notion of sound as a feedback device and as a control mechanism. . In these ways the chapter works toward a more comprehensive understanding of sounds in new media contexts that addresses their particularity in interactive contexts rather than resting on previous assumptions about the primacy of sounds as narrative devices.

Abstract:
AbstractThis research posits an innovative process of embedding carbon fibre as the primary structure within large-scale polymer 3D printed intricate architectural forms. The design and technical implications of this research are explored and demonstrated through two proto-architectural projects, Cloud Affects and Unclear Cloud, developed by the RMIT Architecture Snooks Research Lab. These projects are designed through a tectonic approach that we describe as a super composite – an approach that creates a compression of tectonics through algorithmic self-organisation and advanced manufacturing. Framed within a critical view of the lineage of polymer 3D printing and high tech fibres in the field of architectural design, the research outlines the limitations of existing robotic processes employed in contemporary carbon fibre fabrication. In response, the paper proposes an approach we describe as Infused Fibre Reinforced Plastic (IFRP) as a novel fabrication method for intricate geometries. This method involves 3D printing of sacrificial formwork conduits within the skin of complex architectural forms that are infused with continuous carbon fibre structural elements. Through detailed observation and critical review of Cloud Affects and Unclear Cloud (Fig. 2), the paper assesses innovations and challenges of this research in areas including printing, detailing, structural analysis and FEA modelling. The paper notes how these techniques have been refined through the iterative design of the two projects, including the development of fibre distribution mapping to optimise the structural performance.

Abstract:
AbstractArchitecture has a substantial influence worldwide as it shapes our cities, and it is made to last. Urban areas are also responsible for 70% of the world's carbon emissions. Consequently, architects are responsible for minimising the destructive effects of construction on the environment. How can biological intelligence be inserted in architecture as a possibility to increase environmental performance? Bio-design goes further than biology-inspired approaches. Bio-design refers to incorporating living organisms as an essential component of a system, changing the natural and built environment boundaries. It contains living and machine intelligence, whether embedded in the design process or in the building itself. This paper seeks to give an overview of bio-design and how it can be seen as a strategy of thinking of new research pathways.

Abstract:
As the future orientation of economic and agricultural development, low-carbon agriculture is devoted to reducing the energy inputs and greenhouse gas emissions during the agriculture production. So, it's urgent to take some actions to transit from the current high carbon economy to a low-carbon and high resource efficient economy. This paper examines a two-echelon agricultural product supply chain with a producer and a processor and the market demand is influenced by the retail price and the level of low-carbon technology. The optimal solutions in the decentralized and centralized agricultural product supply chain with or without low-carbon technology are studied. To make the decentralized agricultural product supply chain perform as well as the centralized agricultural product supply chain, the coordination mechanism of the low-carbon supply chain that few of papers focused explicitly on is designed. Finally, extensive numerical experiments are conducted to study the behaviors of supply chain members.

Abstract:
This chapter extends and applies the concepts of Business Intelligence (BI) within business to help improve its environmental performance. When BI is used to improve customer service and optimize business performance, the result can also be used to reduce the carbon footprint of the organization. Various ways to improve customer service as well as cross-selling and up-selling to customers are discussed in the context of the carbon footprint – and with suggestions to improve that footprint. This is a strategic approach to the use of BI in environmental performance – resulting in what is called Environmental Intelligence. The suggestion is to use Business intelligence to improve the overall resources usage (by reducing energy and paper usage) of the organizations without compromising on customer services. For example if the customers are serviced on first contact, the follow on activities involving multiple contacts with customers and marketing paper material could be reduced. This will provide the organizations with better customer satisfaction and also reduce the extra energy usage in developing heavy duty BI infrastructure and paper used for the marketing purpose to woo back the customers.

Abstract:
Xylanases are inducible enzymes responsible for the complete hydrolysis of xylan into xylose. Both solid state fermentation (SsF) and submerged fermentation (SmF) are used in the production of xylanase. SsF has become a popular approach due to its economic value. In fact, higher biomass and lower protein breakdown are among the factors involved in determining the production of xylanases in SsF. Agricultural extracts which are abundantly available in the environment such as rice bran and wheat bran are commonly used as the potential carbon source in xylanases production. Xylanase is indeed one of the valuable enzymes which show immense potential in vast industrial applications. The demand for xylanase is increasing because of its prodigious utilization in pulp and paper, bakery, food and beverage, detergents, textile, and animal feed. Xylanase has therefore become one of the important commercial enzymes in recent years.

Abstract:
When the Arctic (ARC) Long-Term Ecological Research (LTER) project began, I was an aquatic ecologist with experience in managing large projects in freshwaters and estuaries and a specialization in microbes. This project, which studies lakes, streams, and tundras, has greatly increased my breadth as an ecologist and allowed me to take part in terrestrial modeling, microbial studies in streams, and the role of soil mycorrhizal fungi in providing nutrients to many species of plants. As a mentor to several postdoctoral fellows, my LTER research has enabled me to learn about other fields such as the application of molecular biology to microbial ecology. The Arctic LTER project data, the long-term field experiments, and the facilities available at the University of Alaska field station brought me in contact with ecologists from many countries. One result of this association with experts was my coauthorship of a book on Arctic natural history aimed at communicating scientific knowledge to scientists and the general public unfamiliar with the Arctic (Huryn and Hobbie 2012). I have always collaborated extensively with many scientists and encouraged collaboration as the best way to carry out ecosystem research. The Arctic LTER project brought many opportunities to broaden the scope of my collaboration to include terrestrial ecologists and microbiologists. My PhD research was about year-round primary productivity of an Arctic lake but while on a postdoctoral fellowship at Uppsala University, Sweden, I switched to an emphasis on bacterial uptake kinetics in lakes. The techniques I helped develop in freshwater worked in the ocean and estuaries too (Hobbie and Williams 1984). In addition we developed the epifluorescence method for quantifying the abundance of planktonic bacteria. Our paper (Hobbie, Daley, and Jasper 1977) finally convinced oceanographers that bacteria are abundant (at 10⁹ per liter) and important. Recently, I have used my understanding of kinetics of uptake to analyze microbial activity in the soil. My Arctic expertise led to leadership of the aquatic part of the International Biological Program (IBP) at Barrow, Alaska, beginning in 1970. We (28 scientists, graduate students, and postdoctoral fellows) studied shallow ponds to quantify the carbon, nitrogen, and phosphorus cycles.

Abstract:
Carbon-carbon composites possess a number of desirable attributes including low density, high strength and stiffness at temperatures well beyond the capabilities of refractory alloys, low thermal expansion coefficient, tailorable orthotropic properties, absence of strategic materials, and resistance to thermal shock, fatigue, and brittle failures. However, for many applications of interest (such as aircraft and aerospace vehicle structure and engines) resistance to oxidation in high-temperature air or engine exhaust streams is a requirement which is not satisfied by unprotected carbon-carbon composites. The elements of an advanced oxidation protection system for carbon-carbon composites are described in this paper. The system is comprised of both an oxidation resistant coating intended to provide the primary barrier to oxygen ingress and inhibitors added to the matrix of the carbon-carbon composite to increase its oxidation resistance without significant losses in mechanical properties. The composite inhibition system is designed to be complementary to the coating and to enhance its long-term performance. A description of the principal elements of the system is presented along with recent test data and current research directions.

Abstract:
In the past 40 years since China's reform and opening up, the city has been developing rapidly. Small towns are faced with the challenges of extensive development, degradation of human settlements and dif iculty in retaining local characteristics. Therefore, in the development process of small towns, we should not only pay attention to economic development, but also energy conservation and emission reduction, and pay attention to the protection of local characteristics.This paper calculates the carbon emissions of energy consumption in Changxing County from 2002 to 2017, and analyzes the main factors and degree of carbon emissions in Changxing County by using Kaya identities based on the carbon emissions decomposition model. The results show that the carbon emissions of Changxing County increased year by year, but the growth rate showed a downward trend. The ef ect of economic development and energy intensity has a great contribution to the carbon emissions of Changxing County. Industrial structure ef ect, energy structure ef ect and population size ef ect have little contribution to carbon emissions. Combined with the current situation and main factors of carbon emissions in Changxing County, this paper puts forward the compilation ideas and framework of low-carbon planning guidelines of Changxing County from six characteristic spaces , so as to provide the thinking and practical basis for the low-carbon construction of small towns.

Abstract:
Flame retardant property to paper increases the use of paper and the value of paper products. The flame retardant property was achieved by the addition of an organophosphorus agent to the paper. A great deal of research has been done on 9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) derivatives as flame retardants. To apply the flame retardant property in condensed phase, DOPO derivative materials are generally used as an acid source for intumescent flame retardants to promote dehydration and carbonization of the charring agent to form a continuous layer of carbon. In this study, In order to prepare a flame retardant paper coating, DOPO derivative was synthesized with 3-aminophenyl sulfone, and benzaldehyde reaction and the chemical structure of DOPO is illuminated by ATR-FTIR then paper was coating with a flame retardant coating formulation ingredient with DOPO. The paper’s properties were investigated. Surface energy of coated papers and contact angles were determined with goniometer. Printability parameters such as color, gloss, surface tension were examined. The results the study DOPO added paper coatings improve the paper flame retardancy.

Full text
Abstract:
Abstract Bamboo trees are one of the fastest growing trees in tropical rainforests around the world, they have various uses ranging from construction to fly ash generation used in oil and gas cementing, to development of activated carbon which is one of the latest uses of bamboo trees. This paper focuses on development of activated carbon from bamboo trees for carbon capture and sequestration. The need for improved air quality becomes imperative as the SDG Goal 12 and SDG Goal13 implies. One of the major greenhouse gases is CO2 which accounts for over 80% of greenhouse gases in the environment. Eliminating the greenhouse gases without adding another pollutant to the environment is highly sought after in the 21st century. Bamboo trees are mostly seen as agricultural waste with the advent of scaffolding and other support systems being in the construction industry. Instead of burning bamboo trees or using them for cooking in the local communities which in turn generates CO2 and fly ash, an alternative was considered in this research work, which is the usage of bamboo trees to generate activated, moderately porous and high surface area carbon for extracting CO2 from various CO2 discharge sources atmosphere and for water purification. This paper focuses on the quality testing of activated carbon that can effectively absorb CO2. The porosity, pore volume, bulk volume, and BET surface area were measured. The porosity of the activated carbon is 27%, BET surface area as 1260m²/g. Fixed carbon was 11.7%, Volatility 73%, ash content 1.7%.

Abstract:
In the traditional molding process of laminated carbon fiber reinforced C/C composites - preform, it always causes great damage to a high modulus carbon fiber. Research about key factors for jet puncture in multilayer composite material is proposed in this paper. With the method, carbon fiber is added into the laminating direction of high-modulus carbon cloth by using jet method, so the preform is combined together to improve interlayer fiber connection strength in laminating direction (Z direction). Firstly, the key factors in jet puncture process are investigated. Parameter optimization and dynamic modeling of jet process have been studied to explore the mechanism of jet puncture process. Then a fluid simulation is conducted by studying the formation and distribution of diffusion flow field, jet resistance, penetration ability and jet kinetic energy loss. Finally, the fluid software is used to simulate and obtain the optimal structure of carbon cloth and the nozzle. It is expected that this paper can provide a new and effective approach for Z-puncture reinforcement fibers of laminated composite materials.

Veland, Siri, and Christine Merk. Lay person perceptions of marine carbon dioxide removal (CDR) – Working paper. OceanNETs, 2021. http://dx.doi.org/10.3289/oceannets_d3.3.

Full text
Abstract:
This working paper presents first insights on lay public perceptions of marine carbon dioxide removal (CDR) approaches. In seven focus groups, three in Germany and four in Norway (including one pilot) the researchers asked members of the lay public to share their views of the ocean and the effects of climate change, four CDR approaches, as well as their reflections on responsible research and innovation (RRI) of marine CDR. The four CDR methods were ocean iron fertilization, ocean alkalinity enhancement, artificial upwelling, and blue carbon management through restoration of coastal and marine ecosystems. In addition, respondents were asked to compare the four approaches. Our findings indicate that the public will be very supportive of blue carbon management irrespective of its actual carbon sequestration potential, due in part to the perceived bad state of marine ecosystems worldwide. Participants were skeptical whether any of the CDR approaches could have relevant effect on carbon sequestration and long-term storage; they reasoned about issues such as the ability to scale up treatments in time and space, unforeseen or unforeseeable effects on ecosystems in time and space, and the role of industry in the implementation process. They argued that despite the potential availability of marine CDR, industry and the general public should stop polluting behaviors and practices. Nevertheless, the participants universally agreed that further research on all four CDR methods should be pursued to better understand effects on climate, ecosystems, local communities, and the economy.

Abstract:
Boreal ecosystems store large quantities of carbon but are increasingly vulnerable to carbon loss due to disturbance and climate warming. The boreal region in Alaska and Canada, largely underlain by discontinuous permafrost, presents a challenging landscape for itemizing carbon sources and sinks in soil and vegetation. The roles of fire, forest succession, and the presence/absence of permafrost on carbon cycle, vegetation, and hydrologic processes have been the focus of multidisciplinary research in boreal ecosystems for the past 20 years. However, projections of a warming future climate, an increase in fire severity and extent, and the potential degradation of permafrost could lead to major landscape and carbon cycle changes over the next 20 to 50 years. To assist land managers in interior Alaska in adapting and managing for potential changes in the carbon cycle, this paper was developed incorporating an overview of the climate, ecosystem processes, vegetation, and soil regimes. The objective is to provide a synthesis of the most current carbon storage estimates and measurements to guide policy and land management decisions on how to best manage carbon sources and sinks. We provide recommendations to address the challenges facing land managers in efforts to manage carbon cycle processes. The results of this study can be used for carbon cycle management in other locations within the boreal biome which encompasses a broad distribution from 45° to 83° north.
