Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Electronic Journal of Differential Equations, 2015 We study a nonautonomous fourth-order parabolic equation modeling epitaxial thin film growth. It is shown that a pullback attractor of the model exists when the external force has exponential growth.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Spike-Based Bayesian-Hebbian Learning of Temporal Sequences.
PLoS Computational Biology, 2016 Many cognitive and motor functions are enabled by the temporal representation and processing of stimuli, but it remains an open issue how neocortical microcircuits can reliably encode and replay such sequences of information. To better understand this, a

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Exponential attractors of the nonlinear wave equations
Chinese Science Bulletin, 1998 This paper is devoted to the exponential attractors of nonlinear wave equations of the form: \[ \begin{cases} u_{tt}+ \alpha u_t-\Delta u+g(u)= f(x), (x,t) \in\Omega \times\mathbb{R}_+,\\ u|_{\partial \Omega}=0,\;u(x,0)=u_0(x),\;u_t(x,0)= u_1(x).\end{cases} \] The authors prove \(H^1_0(\Omega)\times L^2 (\Omega)\)-type exponential attractors using both

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Advanced Functional Materials, EarlyView.The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.
