Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth

Advanced Functional Materials, EarlyView.
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Silver Ion‐Mediated [hk1]‐Oriented Sb2Se3 Crystal Growth for Efficient Photoelectrochemical Hydrogen Evolution

Advanced Functional Materials, EarlyView.
Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...

Using Long‐Chain Polymechanophores to Explore the Differences in Mechanoactivation During Nozzle Flow and Ultrasonication

Advanced Functional Materials, EarlyView.
Flow through a nozzle is a common component of most fluid‐based polymer processing techniques such as spray drying, inkjet printing, extrusion. An ultrahigh molecular weight multi‐mechanophore system is used to probe the differences in the distribution of mechanical activation observed between nozzle flow and ultrasonication; the gold standard ...

Unique continuation through hyperplane for higher order parabolic and Schrödinger equations [PDF]

Communications in Partial Differential Equations, 2021
Consider the higher order parabolic operator $\partial_t+(- _x)^m$ and the higher order Schr dinger operator $i^{-1}\partial_t+(- _x)^m$ in $X=\{(t,x)\in\mathbb{R}^{1+n};~|t|0$, then the solutions vanish in $X$. Such results are global if $n>1$, and we also prove some relevant local results.
