Artificial particulate matter with high iron content and varied iron speciation accelerates cellulose acetate degradation, increasing chemical instability during aging. These findings identify a previously underexplored deterioration pathway and demonstrate that airborne pollutant composition can critically influence the preservation of historical ...

Fresh Moringa oleifera leaves were evaluated under different drying conditions to identify the treatment with superior retention of bioactive compounds. The selected freeze‐dried extract was used for green synthesis of ZnO nanoparticles, which exhibited characteristic physicochemical properties, concentration‐dependent antioxidant and antibacterial ...

Abstract BACKGROUND An essential aspect of applying Purple Phototrophic Bacteria (PPB) technology for wastewater treatment is the biomass separation from the aqueous phase. Ca2+ and Mg2+ have been used to enhance the aggregation of different biological matrices. In this paper, the effect of Ca2+ and Mg2+ on the aggregation of a mixed culture of PPB was

A Multi‐Crosslinkable Methacrylated Alginate‐GelMa Bioink for Drop‐on‐Demand Bioprinting
A multi‐crosslinkable methacrylated oxidized alginate–GelMA system enables precise drop‐on‐demand bioprinting by integrating tailored polymer functionality with tunable hydrogel properties. The designed macromolecular network combines photochemical, dynamic covalent, and ionic interactions to achieve printable, cytocompatible bioinks for advanced three‐

Abstract Soils of managed boreal forests are a significant carbon (C) reservoir, and maintaining or increasing their ability to store C could play an important role for climate change mitigation. We investigated the effects of forest logging through clearcut and partial cut compared to forest conservation on total soil C stocks, particulate organic ...
