Mechanically Triggered Chemical Recyclable Polyethylene‐Like Materials

Angewandte Chemie, EarlyView.
Polyethylene‐like copolymers with benchmark properties are prepared by embedding latent cyclobutene mechanophores to overcome PE's end‐of‐life limits. The mechanophores are inert in service but are selectively opened by solvent‐free ball milling to yield well‐defined telechelic oligomers.

Ion Charge Compensation upon Electrochemical Doping of Redox Polymer Films with Tunable Crosslinking Density

Advanced Electronic Materials, EarlyView.
The electrochemical doping of redox homo‐ and copolymers containing triphenylamine (TPA) as redox‐active units is reported. Electrochemical crosslinking leads to films with tetraphenylbenzidine (TPB) crosslinking units. Advanced electrogravimetric tools are applied to get insights into their mixed ionic‐electronic conducting characteristics: anion ...

Adhesive Photoinitiator Constructs Polymer Jackets on Enzymes: Direct, Release‐Free Cytosolic Delivery

Angewandte Chemie, EarlyView.
A supramolecular adhesive photoinitiator, GuCD⊃BP‐SH, overcomes a central dilemma in enzyme therapeutics. The initiator, featuring a guanidinium‐modified cyclodextrin (GuCD) host, triggers formation of a semi‐permeable polymer jacket directly on an enzyme.

Stretchable Energy Storage with Eutectic Gallium Indium Alloy

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.

The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

Advanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...

The Typology of the Sapalli Culture Necklaces

Поволжская археология
The Sapalli culture is a culture that was formed in the Northern Bactria region in the Late Bronze Age (2200–1300 BC), and different jewelry (pins, diadems, earrings, beads, necklaces, pendants, amulets, bracelets and rings) have been found at the ...

Low‐Carbon Poly(3‐vinyl‐N‐methylphenothiazine) Electrode Formulation Using PEDOT:PSS (poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate)) for Lithium‐Based Energy Storage

Advanced Energy and Sustainability Research, EarlyView.
Organic electrode materials typically suffer from low electronic conductivity, requiring large amounts of carbon additives. Herein, a conducting polymer, PEDOT:PSS, is introduced as a partial replacement for carbon black, reducing the carbon content to 15 wt%.

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

AIChE Journal, EarlyView.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG$$ {c}_{\mathrm{AG}} $$. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation.

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

American Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Contrasting effects of experimental warming in the initiation year and the flowering year on flower phenology of boreal understory species

American Journal of Botany, EarlyView.
Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.
