Proton exchange membrane fuel cells (PEMFCs) are efficient, low-emission energy sources for vehicles and backup power. The electrode assembly is crucial performance; however, traditional porous carbon supports used catalysts suffer from corrosion, particularly during start-up shut-down cycles, which limits cell durability. In this study, we investigated the effect of nanodrilling on performance durability in PEMFCs. Two commercial blacks were physically activated subjected to treatment using...
Drying characteristics of LGA crystals in this study: with a smaller aspect ratio and larger crystal diameter exhibited lower mother liquor contents faster drying times.
Hollow TiO2 nanoparticles (HNPs) capped with conducting polymers, such as polythiophene (PT), polypyrrole (PPy), and polyaniline (PANI), have been studied to be used polarizability-tunable electrorheological (ER) fluids. The hollow shape of nanoparticles, achieved by the removal SiO2 template, offers colloidal dispersion stability in silicone oil owing high number density. Conducting polymer shells, introduced on nanoparticle surface using vapor deposition polymerization method, improve...
In this study, a flexible all-solid-state asymmetric supercapacitor (FASC) device has been successfully fabricated via full recycling of heated tobacco waste (HTW). Tobacco leaves and cellulose acetate tubes have carbonized (HTW-C) mixed with metal oxides (MnO2 Fe3O4) to obtain highly active materials for supercapacitors. Moreover, poly(lactic acid) (PLA) filters dissolved in an organic solvent the as-prepared using simple paste mixing method. addition, MnO2- Fe3O4-mixed HTW-C/PLA electrodes...
Thanks to the large number of pressurization-induced pores appropriate size and high bulk density, pressurized physically activated carbon showed much higher effective ethanol uptake than chemically carbon.
Analysis of the heavy fractions in crude oil has been important petroleum industries. It is well known that such as vacuum gas oils (VGOs) include heteroatoms, which sulfur and nitrogen are often characterized many cases. We conducted research regarding molecular species analysis VGOs. Further refine processes using VGOs becoming when considering carbon recycling. In this work, we attempted to classify compounds within provided by Kuwait Institute for Scientific Research. Two were priorly...
Recently, due to the rapid increase in demand for artificial graphite, there has been a strong need improve productivity of graphite. In this study, we propose new efficient process by eliminating carbonation stage from existing process. The conventional graphite manufacturing usually involves series stages: pulverization needle-type coke, granulation pitch and coke premix, carbonation, graphitization, surface treatment compensate voids formed within particles. seems time-consuming costly....
Hard carbon derived from green Eucalyptus trees Ethiopia was developed to enhance 1st cycle Coulombic efficiency as the anode for SIBs. Different heat treatment temperatures were applied p...
This study addresses the critical challenge of carbon corrosion in proton exchange membrane fuel cells (PEMFCs) by developing hybrid supports that combine high surface area black (CB) with superior crystallinity and graphitic structure nanofibers (CNFs). Two commercially available CB samples were physically activated composited two types CNFs synthesized via chemical vapor deposition using different sources. The structure, morphology, resulting CNF–CB characterized, performances these...
As the demand for artificial graphite lithium-ion battery (LIB) anode materials is on rise, technologies optimizing manufacturing processes and reducing production costs of are crucial. At same time, globally, regulations generation harmful volatile substances during process also becoming increasingly stringent. In this study, we focused a continuous kneading that minimizes emission graphite. To end, carbonized material was first prepared from mixture needle coke binder pitch processed at...

Introduction Lithium ion batteries (LIBs) and electro double layer capacitors (EDLCs) are regarded as electrical energy storage systems (ESS). LIBs high density, but EDLCs have low density general information. The lithium capacitor (LIC) has advantages of EDLCs. LIC power safety than LIBs. comprises a cathode electrode; active carbon, anode; graphitized carbon. It is similar to LIB EDLC. Porous anodic oxide films aluminum (anodic porous alumina) been widely investigated nano templates...
Electric double-layer capacitors (EDLCs) afford long cycle life and high-power density by dielectric ion adsorption desorption on the surface of porous materials. However, high potential charges/discharges lower capacitance EDLCs. In this study, we quantitatively evaluated large pore-size effect activated carbons (ACs) electric double layer capacitances at various voltages based a hierarchical domain model from structural point view. ACs with highly developed microporous mesoporous (2–4...
Pyrolysis of marine biomass (MB) to create biomass-based carbon materials (MBCs) for coal replacement in ironmaking is a renewable solution. In this study, we systematically examined pyrolysis processes and performed elemental composition analyses MB MBC. The results revealed that MBC contained 12.5–25.5 mass% alkali alkaline earth metals (AAEMs). As the temperature increased, some these AAEMs underwent physical phase changes. Subsequently, applied CO2 aeration washing or acetic acid...
