Abstract:

The paper presents the electrochemical performance of supercapacitor with glass wool separator under organic electrolyte of tetraethylammonium tetrafluoroborate (TEABF4). The performance was evaluated using symmetrical two-electrode system and compared to an identical supercapacitor with commercially available cellulose paper separator under 1 M TEABF4. The application of glass wool separator reduces the bulk resistance of supercapacitor by 19.6%, promotes more efficient ions transfer across active surface of electrode and significantly improves specific capacitance by 19.1% compared to cellul

Abstract:

Distillation is the process of separating two or more components of a liquid based on their boiling points in which the material to be evaporated is contained. Distillation is simply done by heating/evaporating the liquid and then changing the vapor phase to liquid with the help of a condenser. Research on the distillation column or reactor has been carried out to improve the distillation system but is still discussing the reactions that occur due to heating and the final product of the distillation process.

ABSTRACT: Subfertility in stallions is common, and methodologies are needed to increase the fertility in these animals. In other species, removal of the dead sperm from semen increases the quality and fertility of semen. With horse semen we evaluated 48 combinations of column separation techniques using micro‐spin chromatography columns. The greatest improvement in motility was observed with glass wool, whereas glass beads exhibited the greatest recovery of motile sperm. Although centrifugation time did not influence recovery rate or percent motility, a column length of 2 cm was superior for r

Abstract:

Fast pyrolysis of pine wood was carried out to yield a liquid bio-oil mixture that was separated into organic and aqueous phases. The organic phase (ORG-bio-oil) was characterized by gas chromatography–mass spectroscopy, 31P-nuclear magnetic resonance spectroscopy, and Fourier transform infrared (FTIR) spectroscopy. It was further used as a raw material for producing a mixture of biphenolic compounds (ORG-biphenol). ORG-bio-oil, ORG-biphenol, and bisphenol-A were reacted with cyanogen bromide to yield cyanate ester monomers. Cyanate esters were characterized using FTIR spectroscopy and were th

Abstract:

Using bio oil derived from biomass pyrolysis as an alternative fuel continues to be encouraged in order to decrease the utilization of fossil fuels. On the other hand, application of iron ore as a catalyst in the biomass pyrolysis process provides an advantage where there is a mutual effect on the reduction process of iron ore. The objective of the study is to probe the influence of temperature and catalyst concentration to the pyrolysis yields, the characterization of bio-oil gained, and additionally, phase and composition change of the iron ore.

Abstract:

Nanocellulose membranes based on tunicate-derived cellulose nanofibers, starch, and ~5% wood-derived lignin were investigated using three different types of lignin. The addition of lignin into cellulose membranes increased the specific surface area (from 5 to ~50 m2/g), however the fine porous geometry of the nanocellulose with characteristic pores below 10 nm in diameter remained similar for all membranes. The permeation of H2, CO2, N2, and O2 through the membranes was investigated and a characteristic Knudsen diffusion through the membranes was observed at a rate proportional to the inverse

Arjasa is one of Districts located in Kangean Island Madura that has been densely populated by more than 86.000 people. However, the solid waste management system fulfilling the Government Regulation (PP) 81/2012 remains a challenge in the area. The local government has been struggling to provide adequate infrastructure due to their limited resources, let alone local communities’ participation in the waste management. Therefore, this study aims to determine a best-practice solid waste management system in the district. The assessment includes technical aspect (SNI 190394-1994), and in-depth su

The data distribution issue remains an unsolved clustering problem in data mining, especially in dealing with imbalanced datasets. The Kohonen Self-Organising Map (KSOM) is one of the well-known clustering algorithms that can solve various problems without a pre-defined number of clusters. However, similar to other clustering algorithms, this algorithm requires sufficient data for its unsupervised learning process. The inadequate amount of class label data in a dataset significantly affects the clustering learning process, leading to inefficient and unreliable results. Numerous research have b

Abstract:

Lignin recovered from the near-neutral hemicellulose extraction process was investigated as a precursor suitable for production of carbon fiber. Crude lignin was precipitated from the wood extract by adding sulfuric acid to lower the pH value to 1.0. The crude lignin extract was then upgraded by using hydrolysis to cleave lignin-carbohydrate bonds and to remove carbohydrates that contaminate the lignin. The precipitated solids were separated by filtration, washed with water, and then dried. Lignin recovered using the hydrolysis method was found to be high in carbon, high in total lignin, low i

Background: Attitude is a major determinant of health behaviour. Proper management of solid waste at the household level can only be achieved by identifying the attitude of residents towards household solid waste management practices. Solid wastes (SW) are materials created from human activities that are no longer useful. They are disposable solid materials and might be hazardous to human well-being, e.g. plastics, wood, food, textiles, metals, glass, leather, sanitary waste, septic tank waste, etc. Aim: This study assessed the attitude of Abuja residents towards solid waste management practic

Recently, studies on cell surface markers of spermatogonia in combination with germ cell transplantation techniques have made possible the functional analysis of germline stem cells (GS cells). The GS cells are downstream of the stem cells such as ES cells and embryonic germ cells (EG cells), which are derived from primordial germ cells (PGCs). Therefore, GS cells are expected to be useful in the production of genetically modified animals. In this study, we examined the enrichment and cultivation of mouse GS cells by magnetic cell sorting (MACS). Testicular cell suspensions were collected from

Given that global amounts of waste are growing rapidly, it is extremely important to determine what amount of waste will be generated in the near future. Accurate waste forecasting is also important for planning and designing a sustainable municipal solid waste (MSW) management system. For that reason, there is a need to build a model to predict the amount of MSW generated in the near future. Based on previous research, artificial neural networks (ANN) show better results in predicting waste generation compared to other mathematical models. In this research, an ANN model using the iterative al

Drying agricultural products has become an essential technique for preservation, but current drying methods often prove to be energy-intensive, costly, and unsuitable for the needs of local small and medium-sized enterprises (PME/PMI). In this study a hybrid solar dryer has been designed specifically to meet the needs of PME/PMI. The current limits to the development of solar drying in Africa are low efficiency and low autonomy. To remove these bottlenecks, thermal storage and air dehumidification systems are often used. This article firstly, presents a brief review, not only of thermal storag

Over the last few years, there has been a high interest in increasing the energy density of lithium-ion batteries in order to increase the driving range of battery electric vehicles. On a material level, silicon is a promising anode active material candidate due to its high theoretical capacity of 3579 mAh g-1, which is approximately ten-fold higher than that of the currently used graphite anodes with a theoretical capacity of 372 mAh g-1.[1] However, the main drawbacks of silicon are its intrinsic volume expansion of +300 % upon lithiation.[2] This leads to rupturing of the passivating solid
