Summary: In this study, the authors modified 1,4-butanediol (BDO) organosolv pretreatment with different additives to improve the production of fermentable sugars and lignin antioxidants from hardwood and softwood. The additives were found to have a greater impact on the pretreatment efficiency of softwood compared to hardwood. The addition of 3-hydroxy-2-naphthoic acid (HNA) introduced hydrophilic acid groups to the lignin structure, while the addition of 2-naphthol-7-sulphonate (NS) promoted lignin removal, resulting in improved cellulose accessibility for enzymatic hydrolysis. The modified BDO pretreatment achieved near complete cellulose hydrolysis and maximized sugar yield from softwood, while also producing lignin with great antioxidant activity.

Summary: The purpose of this study is to investigate the operating conditions of a physicochemical pretreatment process for lignocellulosic biomass using homogeneous acid catalysts. Four parameters were examined: moisture content, acid catalyst, type of biomass, and reactor morphology. Different types of biomass were processed with sulfuric acid in a meat grinder, and the results showed that biomass moisture above 17% yielded less than 50% glucose. Sulfuric acid exhibited the best performance with a glucose yield of 74.5%, and the glucose yield had a direct relationship with the non-carbohydrate components of biomass.

Summary: Lignocellulose requires pretreatment before hydrolytic enzymes can release fermentable sugars. Sulfuric acid, commonly used for biomass pretreatment, often leads to high levels of degradation products. The study found that pretreatment with maleic acid resulted in the highest release of xylose and glucose among other organic acids. Optimized conditions for maleic acid pretreatment were also identified. The findings suggest that maleic acid could be a viable substitute for sulfuric acid in biomass pretreatment.

Summary: Surface abrasion is a challenging factor for the long-term performance of polymeric materials, and an understanding of the mechanical abrasion of thermoplastics is lacking. This study investigates precision polymer abrasion (PPA) and nanoindentation to determine the extent of controlled wear on three chemically related thermoplastics under varied abrasion conditions. The results indicate that after a single PPA pass, the surface moduli of the polymers increase significantly, while the hardness increases modestly. The dependence of wear volume on the number of PPA passes reaches limiting values for two of the thermoplastics, implying that multiple factors should be considered when describing polymer surface abrasion.

Summary: This study compares the binding and reactivity of 2,4-dichlorophenol (DCP) in two isoforms of dehaloperoxidase-hemoglobin (DHPA and DHPB). DCP is widely used in the chemical industry, present in waste streams, and has particular reactivity to form toxic compounds. The results show that DHPB has 3.5 times higher catalytic efficiency for DCP oxidation than DHPA by a peroxidase mechanism, but both isoforms exhibit self-inhibition at low concentrations of DCP, similar to the inhibition of 2,4,6-trichlorophenol (TCP) at higher concentration.

Summary: The presence of toxic dyes in water threatens environmental safety, making efficient removal of dyes from wastewater highly desired. This study successfully fabricated efficient biosorbents through a simple gelation process of sodium alginate and carboxymethyl chitosan in an acidic aqueous solution. The resulting hydrogel beads showed excellent water absorption properties, pH-responsive swelling characteristics, and high methylene blue (MB) adsorption capacity, comparable to existing lignocellulosic and alginate-based hydrogels. The adsorption mechanism was explained by strong electrostatic forces. This research provides a promising and sustainable approach to dye decontamination.

Summary: This article attempts to provide key insights into various aspects of water solvation through experimental and computational investigations. It suggests that water is not just a common solvent at the molecular level, but can also act as a co-reactant or induce organizational constraints to regulate chemical reactions. The focus is on understanding the stacking of putative water molecules around the three-dimensional network of cellulose, the most abundant biomaterial on Earth, and the impact of hydrogen bonding and water-cellulose molecular architecture on the morphology, properties, and chemical reactivity of micro- and nano-cellulose. The article also introduces the concept of water hydration shells near the hydrophilic surface of cellulose, which can help explain water chemistry and the challenges it poses during drying.
