Impacts of changes in commercial non-coking coal grading system and other coal policies towards estimation of CO2 emission in Indian power sector

open access: yesCarbon Management, 2021
In India, coal-based electricity is a leading cause for greenhouse gas emissions. However, many uncertainties prevail in the emissions estimation from coal-fired plants due to the dynamics of varying net calorific values (NCV) and carbon emission factors

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...
