Redox Flow Batteries: Materials, Design and Prospects

The implementation of renewable energy sources is rapidly growing in the electrical sector. This is a major step for civilization since it will reduce the carbon footprint and ensure a sustainable future. Nevertheless, these sources of energy are far from perfect and require complementary technologies to ensure dispatchable energy and this requires storage. In the last few decades, redox flow batteries (RFB) have been revealed to be an interesting alternative for this application, mainly due ...

Cellulose-Based Carbon Molecular Sieve Membranes for Gas Separation: A Review

In the field of gas separation and purification, membrane technologies compete with conventional purification processes on the basis of technical, economic and environmental factors. In this context, there is a growing interest in the development of carbon molecular sieve membranes (CMSM) due to their higher permeability and selectivity and higher stability in corrosive and high temperature environments. However, the industrial use of CMSM has been thus far hindered mostly by their relative i...

Progress in Upscaling Organic Photovoltaic Devices

Organic photovoltaic (OPV) cells have recently undergone a rapid increase in power conversion efficiency (PCE) under AM1.5G conditions, as certified by the National Renewable Energy Laboratory (NREL), which have jumped from 11.5% in October 2017 to 18.2% in December 2020. However, the NREL certified PCE of large area OPV modules is still lagging far behind (11.7% in July 2020). Additionally, there has been a rapidly growing interest in the use of OPVs for dim light indoor applications, with r...

<p>A comprehensive review of NOx and N2O mitigation from industrial streams</p>

Mitigation of NOx and N2O emissions is a major concern as these substances can cause extensive damages to the atmosphere, soil, water, and humans. Selective catalytic reduction is currently the most effective and widespread technology to remove nitrogen oxides from flue streams. Other methods are also used on a case-by-case basis, most noticeably i) Catalytic decomposition of NOx and N2O, in which nitrogen oxides are decomposed in the absence of other reactants, and ii) selective non-catalyti...
