Highly efficient photoelectrochemical biosensor for the evaluation of bisphenol A-induced microRNA-21 expression alterations.

Herein, we developed a photoelectrochemical (PEC) biosensor integrating SrTiO and SnO materials with a dumbbell DNA mediated target recycling system to quantify microRNA-21 levels under bisphenol A (BPA) exposure.

Enhancing fast-growing wood properties via rosin-modified cellulose: superior hydrophobicity and dimensional stability.

Fast-growing wood is rich in hydroxyl groups, which are sensitive to water and readily absorb moisture in humid environments, leading to a reduction in the mechanical properties of the wood and limiting its applications. Herein, a silicone modified rosin-based hydrophobic agent (SRA) was synthesized from a biomass resource, tetrahydro rosin acids (TRA), and (3-glycidyloxypropyl)triethoxysilane (KH-561) through a ring-opening reaction. The triethoxy groups in the SRA structure facilitate the formation of covalent bonds with the hydroxyl groups of cellulose in the wood, effectively anchoring the active components within the wood matrix and filling its porous structure.

In-situ formation of green rust during Fe(II) coagulation: Dual reductive and adsorptive pathways for dyeing wastewater treatment.

Green rust (GR), a reductive iron-based mineral pivotal in soil and groundwater remediation, remains unexplored for wastewater treatment. This study reveals that high-pH-Fe(II) coagulation enables in-situ generation of stabilized GR, thereby enhancing the coagulation efficiency (> 90 % removal for diverse dyes). The formation mechanism includes three sequential stages: Initially, alkaline conditions facilitate abundant Fe(OH); Subsequently, partial oxidation of Fe(II) by oxidants produces anoxic zones, where Fe(II)/Fe(III) co-precipitation initiates GR crystallization; Simultaneously, multivalent anions intercalate into GR interlayers, further enhancing GR stability through strong electrostatic interactions.
