An overview is presented on the projects that are being carried out by Water Quality and Treatment Laboratory team of LNEC which use activated carbon based technologies for treating water or wastewater. Emphasis is given to the chemical enhancement of conventional wastewater treatment using “green” powdered activated carbon options, hybrid adsorption/ membrane processes or biologically active c...
The commercialization of lithium-sulfur batteries is hindered by low cycle stability and low efficiency, which are induced by sulfur active material loss and polysulfide shuttle reaction through dissolution into electrolyte. In this study, sulfur-impregnated disordered carbon nanotubes are synthesized as cathode material for the lithium-sulfur battery. The obtained sulfur-carbon tube cathodes d...
Amorphous Spherical Carbon with Nitrogen (SCN) active carbon has been prepared by carbonization of poly(vinylpyridine-divinylbenzene) (PVPDVB) copolymer. The PVPDVB dehydrogenation copolymer has been quantum chemically (QC) simulated using cluster and periodic models. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive X-ray (EDX) studies of the resu...
Carbon is the element that contributes towards the hydrophobic effect and biological function of living systems. It is reported that globular proteins prefer to have 31.45% carbon for stability, which can be used as the standard for carbon measurement and comparison. Carbon distribution analysis has been carried out using the tool CARd, which can clearly identify the hydrophobic and hydrophilic...
Rising atmospheric CO(2) levels are predicted to have major consequences on carbon cycling and the functioning of terrestrial ecosystems. Increased photosynthetic activity is expected, especially for C-3 plants, thereby influencing vegetation dynamics; however, little is known about the path of fixed carbon into soil-borne communities and resulting feedbacks on ecosystem function. Here, we exam...
