Transient Stiffness Patterning in Hydrogels Driven by Dissipative Mechanochemical Coupling

open access: yesAdvanced Functional Materials, EarlyView.
Force‐induced disulfide bond rupture in a polymer‐based hydrogel, coupled with chemical or electrochemical reoxidation, leads to the transient modulation of the hydrogel's stiffness properties. High spatiotemporal control is achieved by this dissipative process, enabling the development of out‐of‐equilibrium stiffness patterns and transient, dose ...

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

open access: yesAdvanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Molecular Domino Toppling for Directed Self‐Erasing Information Transfer

open access: yesAdvanced Materials, EarlyView.
An azobenzene‐based material with unprecedented light‐pumped directional charge‐transfer reminiscent of toppling dominoes is presented. After light‐induced trans→cis forward isomerization, electron hopping occurs in a sequential and propagating manner between the cis isomers along with an electrocatalytic cis→trans backward isomerization.

Microfluidic Spinning of PEDOT:PSS Microfibers for Nerve Guidance Conduits

open access: yesAdvanced Materials Technologies, EarlyView.
This publication explores the fabrication of microfluidically spun PEDOT:PSS microfibers for conductive nerve guidance conduits (NGCs). It details the spinning process, fiber characterization, and biocompatibility assessment. The study highlights the fibers' mechanical and electrical properties, non‐cytotoxicity, and potential for nerve regeneration or

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Exercise without Weight Loss Prevents Seasonal Decline in Vitamin D Metabolites: The VitaDEx Randomized Controlled Trial

open access: yesAdvanced Science, EarlyView.
In people with overweight or obesity, regular exercise even without weight loss or vitamin D supplementation completely prevents the usual winter decline in the vitamin D metabolite that maintains health at a cellular level, 1,25(OH)2D3, and ameliorates the decline in the vitamin D status marker 25(OH)D.

Synergistic Modulating of Mitochondrial Transfer and Immune Microenvironment to Attenuate Discogenic Pain

open access: yesAdvanced Science, EarlyView.
Gallic acid (GA) and copper ions self‐assemble to form nanoparticles, which are then modified with mitochondrial targeting peptides and gap junction modulator. These nanoparticles scavenge mitochondrial reactive oxygen species to induce M2 polarization and enhance intercellular mitochondrial transfer.

Trypstatin as a Novel TMPRSS2 Inhibitor with Broad‐Spectrum Efficacy against Corona and Influenza Viruses

open access: yesAdvanced Science, EarlyView.
Trypstatin, a 61‐amino acid Kunitz‐type protease inhibitor derived from human Bikunin, potently inhibits TMPRSS2 and related proteases. It blocks spike‐ and hemagglutinin‐mediated entry of multiple respiratory viruses in vitro reduces SARS‐CoV‐2 replication in human airway cultures, and lowers viral load and symptoms in infected hamsters, demonstrating
