Proton Exchange Membrane Fuel Cells (PEMFCs) and PEM Electrolyzer were characterized using Electrochemical Impedance Spectroscopy (EIS). Faradaic resistance (RΩ), kinetic and mass transfer parameters such as charge ...

One of the global issues acquiring significant attention these days is related to energy supply and demand. The irreversible decrease of fossil fuels left to supply energy and the greenhouse gases increase in the atmosphere ...

Magnetite nanoparticles are currently studied for biomedical applications such as MRI, drug delivery, and magnetic fluid hyperthermia (MHF). These applications require nanoparticles with a suitable coating which provides ...

Polymers are a fundamental part of electronic systems and are widely used due to their low cost, ease of processing, and their wide range of mechanical and electrical properties. They have traditionally been used as passive ...

Hot-melt extrusion has gained significance in the pharmaceutical industry to formulate solid dispersions. In a solid dispersion, poorly-water soluble drugs can be dispersed in an inert hydrophilic polymer matrix, improving ...

Continuous increase in energy demand and high levels of pollution generated by the existing energy sources have led researchers to explore other clean and renewable alternatives. Hydrogen gas (H2) is an option that has ...

Pharmaceutical and personal care products (PPCPs) have emerged in surface water in concentration levels enough to categorize them as “emerging contaminants” due to a lack of efficient wastewater treatment plant removal ...

Nowadays, batch fluid-bed drying is one of the most efficient drying methods for particulate material; but at the same time, it is the most energy consuming operation in the manufacturing of solid dosage forms. To minimize ...

This investigation studied the resulting nanostructure of ionic membranes composed of sulfonated copolymers with thermoplastic and elastomeric blocks. Linear poly(styrene-isoprenestyrene) (L-SIS) and branched poly(styren ...

The production of methanol and dimethyl ether via CO2 hydrogenation was studied using Pd catalysts supported on α-Ga2O3, α-β-Ga2O3 and β-Ga2O3 polymorphs. The catalytic activity improves with the increase in the content ...
