Experimental studies were conducted on 4 groups of 10 rats each: 1) intact animals (a control group); 2) inhalation of carbon disulfide at a concentration of 2.0 mg/m3 for 7 days; 3) prophylactic administration of the hepatoprotective agent Legalon (100 mg/kg of total polyphenols), followed by carbon disulfide inhalation for 7 days; 4) prophylactic administration of the biologically active additive Kalifen (100 mg/kg of total polyphenols for 7 days), followed by carbon disulfide inhalation. Animal survival after carbon disulfide inhalation was 80%; preadministration of Legalon or Kalifen increased survival up to 100%. Carbon disulfide inhalation was attended by abnormal size features of red blood cells, impairments in the antioxidant defense system and the ratio of phospholipid fractions to neutral lipids. Preadministration of Legalon or Kalifen before inhalation contributes to less abnormalities in the study physiological and biochemical parameters of erythrocyte membranes.

Organocatalytic CS insertion into epoxides in neat conditions: a straightforward approach for the efficient synthesis of Di- and tri-thiocarbonates.

The straightforward organocatalytic insertion of carbon disulfide (CS) into epoxides using either choline chloride () or tetrabutylammonium chloride (TBACl) is reported, for the first time, under solvent-free (neat) conditions. Fine-tuning of our system allowed us to obtain either dithiocarbonates (DTCs) or trithiocarbonates (TTCs) with high efficiency. Additionally, a mechanistic proposal is presented, supported by experimental evidence, DFT calculations and wavefunction analyses.

Coalbed methane (CBM) reservoir modification based on chemical solvent treatment could change the coal microstructure, which further affects the adsorption capacity and flow characteristics of this clean energy. Coal samples were extracted by tetrahydrofuran (THF), carbon disulfide (CS), and hydrochloric acid (HCl). Low-pressure nitrogen adsorption, carbon dioxide adsorption, Fourier transform infrared spectroscopy, and methane isothermal adsorption test were adopted.

The rational design of multicomponent heterostructure is an effective strategy to enhance the catalytic activity of electrocatalysts for water and seawater electrolysis in alkaline conditions. Herein, MOF-derived nitrogen-doped carbon/nickel-cobalt sulfides coupled vertically aligned Rhenium disulfide (ReS) on carbon cloth (NC-CoNiS@ReS/CC) are constructed via hydrothermal and activation approaches. Experimental and theoretical analysis demonstrates that the strong interactions between multiple interfaces promote electron redistribution and facilitate water dissociation, thereby optimizing *H adsorption energy for the hydrogen evolution reaction (HER).

Natural building blocks like chitins for self-assembling into complex materials have garnered significant interest owing to the inherent and diverse functionalities. However, challenges persist in the assembly of chitin-based composites, primarily stemming from chitin's poor solubility and compatibility. Herein, a quercetin-mediated multiple crosslinking strategy was developed to enhance compatibility by quercetin-mediated interfacial interactions between chitin and inorganic materials, achieving a series of chitin-based composite hydrogels with high performances.

Anaerobic co-digestion is emerging as an option for wastewater biosolids management. Variations in treatment parameters can impact odour emissions and, in turn, odour nuisance reduces community acceptance and alternatives for beneficial reuse of biosolids via land application. This study assessed odour emissions from digested sludge and biosolids resulting from the anaerobic co-digestion of wastewater sludge with beverage rejects (beer and cola) and food wastes.
