Over the last two decades, Poly(ionic liquid)s (PILs) have undergone extensive research and development. PILs have opened a whole new passage to versatile ionic polymers. It has compelled the chemical industry to rethink its modern ways of carbon capture. PILs have demonstrated excellent CO2 sorption capacities in comparison to their corresponding Ionic Liquids (ILs). The effects of the chemical structures of PILs on CO2 so Read More

Carbon Dioxide (CO2) capture has been widely accepted to be a prerequisite strategy to mitigate the increase of CO2 concentration in the atmosphere. Membrane separation has been envisaged to be one of the most promising technologies for CO2 capture due to its small footprint, simple up- and down-scaling, and low impact on the environment. Owing to their extraordinary high CO2 permeability and moderate CO Read More

Background: Excessive use of fossil energy has exacerbated global warming, and the goal of carbon neutralization has been put on the agenda. In order to make full use of renewable energy and reduce greenhouse gas emissions, it is urgent to develop environment-friendly energy storage devices. We previously reported metal sulfides/ graphene nanocomposites for the applications in supercapacitors (I. NiS/graphene). Rec Read More

Objective: To explore the drag reduction effect of surfactant-polymer composite system in a turbulent flow. Methods: The turbulent drag reduction experiment of the one-component solution and the composite solution was carried out in a rectangular pipeline platform, respectively. Moreover, Particle Image Velocimetry (PIV) was utilized to measure the turbulent flow field of the drag-reducing flow. Results: Experimental results Read More

Introduction: The effects of different physical activation agents on carbon material pore development and the subsequent methane adsorption were studied. Methods: Palm Kernel Shell (PKS) as a carbon precursor was pre-treated with ZnCl2 and activated for two hours with (i) CO2, (ii) steam, and (iii) the combination of CO2 and steam (in series). Results: The findings indicate that the combination of two activation agent Read More

Aim: The major goal of this fascinating study was to determine the molecular interaction of the polymer dextran with urea in an aqueous media using a more straightforward technique. Background: Many physical approaches play important roles in identifying the molecular structure and molecular characteristics of various solutions. In recent years, advances in ultrasonic methods have become a potent tool for assessing Read More
