Carbon dioxide-mediated catalytic pyrolysis of lignin in syngas production.

Kraft lignin (KL), a byproduct of the pulp and paper industry, is commonly combusted as a low-grade fuel. However, its high sulphur content results in the emission of sulphur oxides, which pose environmental hazards. This study explores a sustainable approach for the valorisation of waste KL into syngas via CO-mediated pyrolysis.

Integrated role of biochar and PGPR (Leclercia adecarboxylata HW04) in enhancing cadmium phytoremediation and stress tolerance in Glycine max L.

Plant growth-promoting rhizobacteria (PGPR) and biochar (BC) are recognized as effective biological agents for enhancing stress tolerance and mitigating heavy metal toxicity in crops. Therefore, this study aims to investigate the effects of the cadmium (Cd)-resistant PGPR strain Leclercia adecarboxylata HW04 (>4 mM Cd resistance) on soybean plants exposed to 300 μM Cd. HW04 was observed to possess the innate ability to synthesize indole-3-acetic acid and exopolysaccharides, which facilitated the absorption of Cd in the medium.

Pathway Analysis of Allulose as a Sugar Substitute in Mitigating Thrombotic Risks in Sickle Cell Disease Patients.

Long-term consumption of erythritol, a widely used sugar substitute, has been associated with increased risks of thrombosis and cardiometabolic diseases. In this study, we investigated the effects and mechanisms of allulose in mitigating these risks compared to erythritol using the clusterProfiler tool in R (version 4.12.

Insect-derived biochar for CO adsorption under humid conditions: Elucidating adsorption mechanisms and competitive interactions with water molecules.

The CO adsorption capacity of biochar depends on the type of biomass used and its physicochemical properties; various sorption parameters including temperature, CO concentration, and humidity affect the CO adsorption capacity. Biochar derived from defatted black soldier fly larvae (BSFL) biomass was investigated for direct CO capture and exhibited a hydrophilic/mesoporous structure that contained high concentrations of alkali and alkaline metals (>10 wt%), which contribute to CO chemisorption. The CO adsorption efficiency was higher at 25 °C compared with that at 30 °C and 35 °C, probably due to reduced Brownian motion of CO molecules at lower temperatures.
