Solvent‐Free Manufacturing of Multifunctional Gas Diffusion Electrode Architectures for Enhanced CO2 Conversion From Low‐Concentration Streams

Advanced Functional Materials, EarlyView.
A tandem gas diffusion electrode (GDE) leveraging hierarchically engineered microgranules enables efficient CO2 electroreduction under dilute CO2 conditions. A key innovation lies in the solvent‐free precision assembly of metal–organic‐frameworks, carbon nanotubes, and copper nanoparticles.

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

Advanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

Nonexistence of positive global solutions for singular differential inequalities on exterior domains of the Heisenberg group

Electronic Journal of Qualitative Theory of Differential Equations
This paper investigates the nonexistence and existence of global weak solutions to semilinear differential inequalities in the exterior domain of the unit ball within the Heisenberg group $\mathbb{H}^N$.

Sprayable Polymer Blends With Short‐Chain Surface Segregation for Preventing Postoperative Abdominal Adhesions

Advanced Healthcare Materials, EarlyView.
Adhesions’ high occurrence rates and high morbidity render them a critical challenge to be addressed. Current prevention methods, such as physical barriers, have many limitations, resulting in inconsistent safety and efficacy. This study demonstrates the potential for sprayable polymeric materials as an adhesion barrier.

Existence, decay and blow up of solutions for the extensible beam equation with nonlinear damping and source terms

Open Mathematics, 2015
We consider the existence, both locally and globally in time, the decay and the blow up of the solution for the extensible beam equation with nonlinear damping and source terms.

Construction of blow-up solution for 5-dimensional critical Fujita type equation with different blow-up speed

Journal of Fixed Point Theory and Applications, 2023
Abstract We are concerned with blow-up solutions of the 5-dimensional energy critical heat equation $u_t=\Delta u + | u |^{\frac{4}{3}}u$. Our main result is to show that the existence of type II solutions blows up at any k points with arbitrary k blow-up rates. The inner-outer gluing method has been employed.

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Uniform Blow-Up Rates and Asymptotic Estimates of Solutions for Diffusion Systems with Nonlocal Sources

Differential Equations and Nonlinear Mechanics, 2007
This paper investigates the local existence of the nonnegative solution and the finite time blow-up of solutions and boundary layer profiles of diffusion equations with nonlocal reaction sources; we also study the global existence and that the rate of ...
