Mathematical Behavior of Solutions of Fourth-Order Hyperbolic Equation with Logarithmic Source Term

, 2019
The main goal of this paper is to study for a fourth-order hyperbolic equation with logarithmic nonlinearity. We obtain several results: Firstly, by using Feado-Galerkin method and a logaritmic Sobolev inequality, we proved local existence of solutions. Later, we proved global existence of solutions by potential well method.

Framework Flexibility on Water Sorption and Transport in ZIF‐90: Insights from Neural‐Network Molecular Dynamics

Advanced Materials Interfaces, EarlyView.
A DeepMD‐based molecular dynamics framework is developed to investigate water adsorption in ZIF‐90, explicitly accounting for framework flexibility. Results show that atomistic flexibility significantly influences adsorption energetics, diffusion, and structural correlations, yielding nearly constant heat of adsorption and enhanced mobility.

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Thermal Enhancement of TADF‐OLED Performance: Size of Active Area Matters

Advanced Materials Interfaces, EarlyView.
Large‐area TADF‐based OLEDs can be used as thermally assisted light‐emitting devices, in which moderate waste heat can partially compensate for efficiency losses associated with increasing active area. ABSTRACT Temperature significantly impacts the performance of light‐emitting diodes, typically causing degradation as they heat up. However, OLEDs using

Laser‐Induced Local De‐Doping in Organic Semiconductors

Advanced Materials Technologies, EarlyView.
The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Open source virtual environments in computer forensics

, 2008
In this paper we discuss the potential role of virtual environments in the analysis phase of computer forensics investigations. We argue that commercial closed source computer forensics software has certain limitations, and we propose a method which may ...
