Boundedness in a quasilinear two-species chemotaxis system with consumption of chemoattractant

Electronic Journal of Qualitative Theory of Differential Equations, 2019
This paper deals with a two-species chemotaxis system \begin{equation*} \begin{cases} u_t=\nabla\cdot(D_1(u)\nabla u)-\nabla\cdot(u\chi_1(w)\nabla w)+\mu_1 u(1-u-a_1v),\quad &x\in \Omega,\quad t>0,\\ v_t=\nabla\cdot(D_2(v)\nabla v)-\nabla\cdot(v\chi_2(w)\

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Existence and Maximal Regularity of Solutions for a Class of Third-Order Differential Equations with an Unbounded Coefficient

Mathematics
This paper investigates a class of third-order partial differential equations with an unbounded lower-order coefficient in the Hilbert space L2(R2). The study is motivated by the wide use of third-order equations, particularly of Korteweg–de Vries type ...

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Maximal regularity for the damped wave equation

, 2018
We consider the problem of maximal regularity for non-autonomous Cauchy problems ¨ u(t) + B(t) ˙ u(t) + A(t)u(t) = f (t) (t ∈ [0, τ ]), u(0) = u 0 , ˙ u(0) = u 1. Here, the time dependent operator A(t) is bounded from V to V ′ and B(t) is associated with

Enhancing Bubble Removal in Geometry‐Optimized Electrodes

Advanced Engineering Materials, EarlyView.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

Continuous Maximal Regularity and Analytic Semigroups

, 2011
In this paper we establish a result regarding the connection between continuous maximal regularity and generation of analytic semigroups on a pair of densely embedded Banach spaces.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.
