Several new chiral cyclic hypervalent iodine(III) reagents have been synthesized and characterized. Carbon‐based ligands were successfully installed onto the hypervalent iodine centers, giving thus access to novel chiral cyano‐, trifluoromethyl‐ or alkynyl‐bearing λ3‐iodanes.

A bio‐derived triple‐helix framework enables adaptive interphase engineering for aqueous Zn metal batteries. Directional Zn2+ migration channels and dynamic transformation into β‐sheet domains construct an optimized solid electrolyte interphase with flexible–rigid synergy, delivering dendrite‐free Zn deposition and exceptional long‐term battery cycling

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

Polyglycine Strands Within a Collagen Triple Helix
ABSTRACT The collagen triple helix is the most abundant protein structural motif in animals. It tolerates any amino acid in its Xaa and Yaa positions but demands glycine (Gly) at every third position, where the residue packs into the sterically forbidding core of the triple helix and donates the recurring interstrand N–H⋯OC hydrogen bond that stitches

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Nucleophilic Aromatic Substitution in the Gas Phase
In this review, we highlight experimental studies of gas‐phase SNAr. Studying reactions in the gas phase provides invaluable information on intrinsic reactivity by eliminating the complications of solvent effects. Because SNAr is a fundamental reaction in chemical research and organic synthesis, understanding its underlying reactivity and mechanisms is

Direct Access to Chiral Piperidines by Enantioselective HAT‐Initiated C(sp3)─H Oxidation
The direct desymmetrization of piperidines is achieved through manganese‐catalyzed enantioselective α‐C(sp3)─H oxidation with hydrogen peroxide, affording versatile chiral N,O‐acetals in good yields and with high enantio‐ and diastereoselectivity. These intermediates provide access to diverse functionalized piperidines with retention of chirality ...
