High-Performance Supercapacitor Electrode Materials from Cellulose-Derived Carbon Nanofibers
Get PDFNitrogen-functionalized carbon nanofibers (N-CNFs) were prepared by carbonizing polypyrrole (PPy)-coated cellulose NFs, which were obtained by electrospinning, deacetylation of electrospun cellulose acetate NFs, and PPy polymerization. Supercapacitor electrodes prepared from N-CNFs and a mixture of N-CNFs and Ni(OH)2 showed specific capacitances of ∼236 and ∼1045 F g-1, respectively. An asymmetric supercapacitor was further fabricated using N-CNFs/Ni(OH)2 and N-CNFs as positive and negative electrodes. The supercapacitor device had a working voltage of 1.6 V in aqueous KOH solution (6.0 M) with an energy density as high as ∼51 (W h) kg−1 and a maximum power density of ∼117 kW kg-1. The device had an excellent cycle lifetime, which retained ∼84% specific capacitance after 5000 cycles of cyclic voltammetry scans. N-CNFs derived from electrospun cellulose may be useful as an electrode material for the development of high-performance supercapacitors and other energy storage devices
Sentence Analysis of Haruki Murakami’s Norwegian Wood
Get PDFThe study of an author’s unique writing style, specifically the utilization of different sentence patterns and individual diction, is commonly lacking in most craft writing classes or entry level grammar classes, but this study can provide valuable insight into how a particular author’s writing style is made effective and encourages readers to keep reading. The purpose of this study is to analyze world renowned author Haruki Murakami’s style in his novel Norwegian Wood in terms of sentence structure, and examine the deeper structures of his writing by utilizing the ten basic sentence patterns. Within this study, a new method of style analysis is utilized. The Reed-Kellogg system is employed to create a visualized representation of Murakami’s style, allowing for a close examination of the structure of writing within his novel. The results of this study show that Haruki Murakami most often used simple, indicative sentences in the simple past tense and active voice
Manyfishes 1: A Standardized Test of Inhibitory Control in Fishes Using Big Team Science
Get PDFAlthough fish behavior research has a reasonably long history, the past decade has seen a dramatic increase in the number of studies on fish cognition. Yet, there exist important limitations to our assessment of fish cognition that can lead to replicability issues, including the use of small sample sizes, nonrepresentative samples, and unstandardized protocols. Recently, several Big Team Science initiatives have begun to address this problem in various taxa (e.g., ManyBabies, ManyPrimates, ManyBirds, ManyDogs). In the same spirit as its predecessors, ManyFishes uses an approach based on large-scale collaboration across researchers and institutions in an attempt to increase both the number and diversity of fish samples used in cognitive and behavioral research. Here, we tested Lamarck’s angelfish (Genicanthus lamarck, N = 7) in a pilot version of ManyFishes 1, the first-ever study of the ManyFishes project that uses a standardized version of the cylinder task—a detour paradigm widely used in comparative psychology—to assess inhibitory control capacities in fishes. In the task, subjects must swim around a clear cylinder to obtain a food reward located inside the cylinder; importantly, to succeed, they must “detour” the obstacle by inhibiting their motor impulses to reach for the food directly, thus avoiding to bump or touch the cylinder walls along the way. We discuss the results of our pilot study, both advantages and challenges of the experimental procedure, and the implication of our findings for the ManyFishes project
Effect of Flame-Retardants on the Properties of Vegetable Oil-based Polyurethane Foams
Get PDFPolyurethanes (PUs) can be made from a range of starting materials and are used in a variety of practical applications, including foams, coatings, adhesives, and sealants. In general, PUs are synthesized by reacting polyols with isocyanate. Traditional polyols are usually made from petroleum-based sources. The production of bio-based polyols from vegetable oils would reduce dependency on fossil fuels and the environmental effects associated with the mining and consumption of petroleum-based products. PU foams can catch fire due to their porous structure, hence the use of flame retardants is critical. Vegetable oil-based polyol was synthesized using an epoxidation reaction of double bonds followed by ring-opening. A halogen-free flame retardant (DPPMA) using melamine and diphenyl phosphonic acid was synthesized. The three sets of PU foams were created using three different flame retardants in varying quantities: melamine (MA), dimethyl methyl phosphonate (DMMP), and melamine salt (DPPMA). The closed-cell content of MA-containing foam was 90%, whereas DMMP and DPPMA foams showed a declining tendency at larger loadings. The TGA and compression strength tests showed strong thermal stability at high temperatures. All the foams showed good compression strength. During the burning tests, all foams indicate a decrease in weight loss and burning time with an increase in the amount of FRs in the foams. Among the three FRs, the DMMP showed the shortest burning time and the highest compression strength. Our research suggests that vegetable oil-based polyol could be used as a substitute for petroleum-based polyol, and the addition of MA, DMMP, and DPPMA can significantly reduce the flammability of PU foams
Farmers Adoption of Precision Farming in Agriculture
Get PDFTo give detailed study about how farmers adopt precision farming in agriculture to get the revenue more profitable with using modern technology to grow crops in the organic manner. Farmers can improve crop yields and assist decisions about the correct selection of crop based on the soil, pesticides, and irrigation process. In this study farmers with 20 or more acres of land taken to complete the survey because precision farming can be done successfully in more acres of land. Precision farming can reduce reduction of the use of more inputs to the yields and labor thus reduce costs and can also make the efficiency in the use of water and the quality of the product can be increased. Precision farming can be used with GPS technology to automatic use of the machines in the field. The main goal of precision farming is to define a decision-making system for whole farm management with optimizing returns on inputs while using resources. Precision agriculture can use tools such as tractors, combines, sprayers and planters. To collect the data, I’m using the Pearson correlation coefficient using R and scatter plots using Excel to show the graph of the crop yields in the last 5 years with increased in revenue
Transition Metal-based Electrocatalysts for Water-Splitting Applications
Get PDFHydrogen is considered as one of the most efficient and green fuels. Hydrogen can be produced via water water-splitting process, however, an efficient electrocatalyst is required to make this process cost-effective. In this work, a transition metal-based electrocatalyst was designed to reduce the overpotential and increase the efficiency of the water-splitting process. The performance of the electrocatalyst is found to be largely dependent on its structure, phase, morphology, electronic environment, and number of active sites. The phase and morphology of iron oxide (Fe3O4@Ni-Foam) were tuned by sulfurization and phosphorylation to produce FeS and FeP, respectively. The synthesized electrocatalysts were characterized using structural and electrochemical testing processes. FeS and FeP showed nanoflower and nanoneedles-like morphologies, respectively. During electrochemical studies, FeP was shown to be the most effective electrocatalyst for the oxygen evolution process (OER), the urea oxidation reaction (UOR), and seawater electrolysis. The overpotentials observed for OER, UOR, and seawater splitting were significantly reduced when using FeP as compared to other materials, with values of 207 mV, 133 mV, and 287.1 mV, respectively, at a current density of 10 mA/cm2. The enhanced catalytic activity of FeP over FeS and Fe3O4 could be attributed to morphological changes, improved electronic conductivity, and exceptional endurance. This work suggests that sulfurization and phosphorylation of transition metal oxide/hydroxide can tune the morphology and electrochemical properties and thus can improve the electrocatalytic activity of transition metal-based nanomaterials
