Chalcogen‐Bond‐Driven Electrochemical Bromide Sequestration in Benzothiazole‐Functionalized Covalent Organic Frameworks

Angewandte Chemie, EarlyView.
To address the unresolved challenge of selective bromide removal from reverse‐osmosis permeate, we developed benzothiazole‐functionalized COF/rGO electrodes that exploit directional chalcogen bonding to preferentially capture Br− over Cl−. The mesoporous BTzTp@rGO electrode achieved a maximum Br− uptake of 36.7 mg g−1, a Br−/Cl− selectivity factor of ...

Z‐Retentive Enantioselective Rh‐Catalyzed Hydroarylation of E,Z‐Dienes

Angewandte Chemie, EarlyView.
The Rh‐catalyzed hydroarylation of conjugated E,Z‐dienoates is found to proceed with high selectivity for addition to the E‐alkene unit. Mechanistic analysis of this Z‐retentive process points towards preferred binding of the E‐alkene unit to a Rh‐aryl species to give rise to the observed selectivity and that Rh‐enolate protonolysis to be turnover ...

Extending Peptide Ligation to Acidic pH and Junctions Comprising Glycosylated and Phosphorylated Amino Acids

Angewandte Chemie International Edition, EarlyView.
A pyridine‐containing ligation auxiliary eliminates a major bottleneck of peptide ligation chemistry. The extended range of applicable pH values (2.0–7.5) in the ligation reaction helps to avoid epimerization. Native chemical ligation (NCL) proceeds at virtually any junction, including reactions at β‐branched amino acids, as well as O‐glycosylated or O‐

Comparative Performance of Poly(Vinyl Alcohol)/Chitosan Hydrogels Reinforced With Kraft Lignin and Kraft Lignin Nanoparticles

Journal of Applied Polymer Science, EarlyView.
The use of kraft lignin and kraft lignin nanoparticles in poly(vinyl alcohol)/chitosan hydrogels was comprehensively compared. The results showed that a higher loading of lignin nanoparticles than bulk kraft lignin could be incorporated while maintaining favorable hydrogel properties, leading to improved overall performance. ABSTRACT The development of

Engineering Biology Beyond Single Genes: Advances and Challenges in Multiplex Genome Editing

Animal Research and One Health, EarlyView.
Multiplex genome editing is transforming genome engineering from single‐gene perturbation to network‐level control, yet its broader application remains limited by challenges in gRNA array engineering, delivery technologies, and safety management. Emerging AI‐driven approaches are accelerating guide RNA design and CRISPR effector optimization for ...

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

Design of azine antioxidants for sustainable biodiesel: integrating structural characterization and molecular modeling

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The growing global demand for sustainable energy solutions has intensified the search for renewable alternatives to fossil fuels, with biodiesel emerging as a promising candidate due to its biodegradability and lower emissions. However, its large‐scale application is limited by low oxidative stability, which compromises storage and performance.

Incorporating Scaffolded Signature Assignments Throughout the Curriculum to Evaluate Biochemistry Program Learning Outcomes

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT A curriculum reevaluation in the College of Natural Sciences at the University of Texas at Austin led to changes in the biochemistry degree plan, which facilitated the development of signature assignments for program evaluation. Developed through backward design using program learning outcomes (PLOs), these signature assignments were used to ...

Quercetin‐zinc coordination polymer coated CaCO3 nanoparticles potentiate radiotherapy through reprogramming tumor immunosuppression

BMEMat, EarlyView.
Synthesis of QZCaCO3‐PEG to synergistically enhance the immunogenicity of radiotherapy through concurrent Zn2+‐induced cancer cell pyroptosis and Que‐mediated hypoxia amelioration through sequentially suppressing TGF‐β secretion and ECM deposition. Abstract Radiotherapy has demonstrated broad applications in treating solid tumors, but the hostile tumor
