A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

open access: yesAdvanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

Effects of Bisphenol A Stress on Activated Sludge in Sequential Batch Reactors and Functional Recovery

open access: yesApplied Sciences, 2022
This study assessed the toxic effects of bisphenol A (BPA) on the microbial community and the function of activated sludge in sequencing batch reactors (SBRs). The toxicity of BPA was mitigated through dosing sludge with Rhodococcus Req-001.

Bisphenol A induces superfeminization in the Ramshorn snail Marisa cornuarietis (Gastropoda: Prosobranchia) at environmentally relevant concentrations [PDF]

open access: yes, 2007
Previous investigations have shown that bisphenol A (BPA) induces a superfeminization syndrome in the freshwater snail Marisa cornuarietis at concentrations as low as 1 μg/L.

Expressiveness modulo Bisimilarity of Regular Expressions with Parallel Composition (Extended Abstract) [PDF]

open access: yes, 2010
The languages accepted by finite automata are precisely the languages denoted by regular expressions. In contrast, finite automata may exhibit behaviours that cannot be described by regular expressions up to bisimilarity.

Regulation of Excitonic Behavior in Defective Acetylenic Polymers Enables Mechanism Switching in O2 Activation for Enhanced Water Decontamination

open access: yesAdvanced Science, EarlyView.
A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...

Important roles of Hif1a in maternal or adult BPA exposure induced pancreatic injuries

open access: yesScientific Reports, 2023
Bisphenol A (BPA) is a monomer to produce polycarbonate plastics and can be released into the environment through human activities, leading to its accumulation in animals, plants and humans through direct contact or environmental exposure ...

Principles for Rigorous Design and Application of Synthetic Microbial Communities

open access: yesAdvanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction
