J Mater Chem B. 2026 Apr 16. doi: 10.1039/d6tb00112b. Online ahead of print. ABSTRACT A high-performance organic photoelectrochemical transistor (OPECT) sensor was successfully constructed based on a ZnCdS/Ce-MOF composite gate integrated with a self-replicating catalytic hairpin assembly (SRCHA) signal-amplification strategy, which enables ultrasensitive and highly selective detection of the pesticide imidacloprid. The sensor employs visible-light-responsive…

Angew Chem Int Ed Engl. 2026 Apr 10:e9334343. doi: 10.1002/anie.9334343. Online ahead of print. ABSTRACT Dynamic sub-compartmentalization and internal organization are important assets of living cells to control functional complexity. Mimicking these features in artificial cells provides a platform to effectively respond to external cues by changing internal structure, thereby emulating life-like behavior. Here, we…

Res Sq [Preprint]. 2026 Apr 3:rs.3.rs-9204910. doi: 10.21203/rs.3.rs-9204910/v1. ABSTRACT Stereoselective nucleophilic substitution to access α tertiary amines relies on copper catalyzed radical approaches in which the substitution is mediated by metal-anilide coordination.1 These systems, however, are constrained by competing arene radical alkylation pathways.2 Here we report a distinct photoenzymatic mechanism for enantioconvergent nucleophilic substitution that…

Chem Catal. 2026 Feb 19;6(2):101607. doi: 10.1016/j.checat.2025.101607. ABSTRACT Vitamin B12 (VB12), one of nature’s most versatile cofactors, performs a multitude of radical and polar steps carefully choreographed by its surrounding enzyme microenvironment. It is highly desirable to capture this variegated reactivity in synthetic applications as well; however, few design principles for controlling VB12 reactivity have…

Chemphyschem. 2026 Apr 14;27(7):e202500905. doi: 10.1002/cphc.202500905. ABSTRACT Krokinobacter eikastus rhodopsin 2 (KR2) is a microbial light-driven ion pump that transports Na+ out of the cell. The active transport is coupled to a photocycle of the retinal chromophore, covalently attached to the protein via a Schiff base linkage. In this work, we have employed time-resolved pump-probe…

RSC Adv. 2026 Apr 7;16(20):17972-17982. doi: 10.1039/d6ra01041e. eCollection 2026 Apr 1. ABSTRACT A visible-light-driven photoredox protocol for the α-amino C(sp3)-H heteroarylation of N-aryl pyrrolidines and piperidines with 2-chlorobenzothiazole derivatives in batch and in flow conditions is developed. The transformation proceeds under mild conditions using an iridium photocatalyst in the presence of water, providing efficient access…

J Am Chem Soc. 2026 Apr 8. doi: 10.1021/jacs.6c00570. Online ahead of print. ABSTRACT Photoenzymatic reduction of CO2 to formate is a promising strategy for carbon valorization, yet its efficiency is still limited by inefficient energy and mass transport. Here, we design a series of isostructural hydrogen-bonded organic frameworks (HOFs) that establish confinement effects to…

Small. 2026 Apr 5:e73308. doi: 10.1002/smll.73308. Online ahead of print. ABSTRACT In nature, photocatalytic reduction of carbon dioxide is a critical process for maintaining the global carbon cycle, which is initiated by the enzymes consisting of chromophoric organic macrocycles in the presence of water. It is extremely desirable to develop an artificial organic photosynthetic system…

Arch Orthop Trauma Surg. 2026 Mar 28;146(1):127. doi: 10.1007/s00402-026-06278-4. ABSTRACT INTRODUCTION: The purpose of this study was to perform biomechanical pull-out comparisons between composite bone blocks and additively manufactured bone models using locked plate and screw systems. The hypothesis posited that the mean pull-out force of the 3D-printed models would demonstrate non-inferior pull-out strength compared…

Inorg Chem. 2026 Mar 27. doi: 10.1021/acs.inorgchem.5c05807. Online ahead of print. ABSTRACT Supramolecular host-guest systems have long served as models for understanding receptor-substrate interactions and enzyme-like behavior. In fact, they can also serve as a powerful tool to study competition for substrates in a crowded cellular milieu, where many distinct proteins can bind the same…
