Combustion behaviour of some biodesulphurized coals assessed by TGA/DTA [PDF]

, 2009
Thermal analysis, i.e. TGA/DTA is used to study the changes in the combustion behaviour of microbially treated coals. In view of their high sulphur content and industrial significance three samples are under consideration, i.e.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.
