SIRT7‐Mediated H2BK120 Succinylation Drives Aberrant Mitophagy in Sepsis‐Associated Cognitive Dysfunction

Advanced Science, EarlyView.
Sepsis triggers hippocampal SIRT7 loss, promoting histone H2B succinylation and activation of the PD‐1/PD‐L1–PINK1 axis. This metabolic‐epigenetic cascade drives aberrant mitophagy and neuronal injury, ultimately causing cognitive deficits. Targeting SIRT7‐dependent succinylation offers a potential strategy to protect brain function during sepsis ...

A Scalable Double‐Sided Wet Etching Strategy for Large‐Area Mushroom‐Shaped Bionic Adhesives

Advanced Science, EarlyView.
This work presents a scalable manufacturing strategy for high‐performance, large‐area, mushroom‐shaped bio‐inspired adhesives. Using a double‐sided wet etching process, the complex 3D metal molds are fabricated rapidly and controllably. The resulting adhesive structures exhibit strong, stable adhesion under various conditions, including atmosphere and ...

Modelling procedures and properties of rubber in rolling contact

, 2013
Rubber covered cylinders in rolling contact are studied in two cases; rolling over a flat surface and rolling over a groove. In the first case, two different finite element procedures are compared for the purpose of investigating if computational savings

Shear‐Mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals

Advanced Science, EarlyView.
Periodic shear‐induced electric current measurements are reported on two archetypic ferroelectric nematic liquid crystal compounds. From the temperature, frequency and shear angle dependent results of the first and second harmonic current signals together with temperature and oscillatory rheology measurements, the effective piezoelectric coupling ...

First principles phase diagram calculations for the cdse-cds wurtzite, zincblende and rock salt structures [PDF]

Computer Methods in Materials Science, 2013
The phase diagrams of CdSe1-xSx alloys were calculated for three different crystal structure types: wurtzite (B4); zinc-blende (B3); and rocksalt (B1). Ab initio calculations of supercell formation energies were fit to cluster expansion Hamiltonians, and

Stochastic Locomotion Emerging From Body–Environment Interactions in a Mexican Jumping Bean–Inspired Robot

Advanced Intelligent Systems, EarlyView.
Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...
