An Interior Gradient Estimate for a class of Second Order Partial Differential Inequalities [PDF]
arXiv, 2010 A uniform gradient for functions u which satisfy a system of N second-order partial differential inequalities is given in this paper. Some structure conditions are given for the coefficients of the matrices of second-order terms and of first-order terms.

In Situ Manipulation of Growth Mechanisms in the Vapor–Solid–Solid Growth of GaP Nanowires
Advanced Materials Interfaces, EarlyView.The direct observation of the Ni‐assisted GaP nanowire growth process via transmission electron microscopy reveals two different growth mechanisms by Trimethylgallium (TMGa) precursor supply variations. The decrease of TMGa flow results in the formation of Ni2P phase as growth promoters with cation exchange reaction in addition to interface diffusion ...

The complexity of numerical methods for elliptic partial differential equations
Journal of Computational and Applied Mathematics, 1978 AbstractWe consider three Ritz-Galerkin procedures with Hermite bicubic, bicubic spline and linear triangular elements for approximating the solution of self-adjoint elliptic partial differential equations and a collocation with Hermite bicubics method for general linear elliptic equations defined on general two dimensional domains with mixed boundary ...

Advanced Materials Interfaces, EarlyView.A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

Stopping a Multilayered Co‐Axial Flow in a 3D Printed Microchannel with Cascaded Nozzles
Advanced Materials Technologies, EarlyView.A microfluidic device with cascaded nozzles is 3D‐printed using two‐photon polymerization. Its microchannel, featuring integrated nozzles, sculpts multilayered co‐axial flows, enabling independent regulation of four co‐flowing streams to achieve variable layer thicknesses.

Boundary value problems for elliptic partial differential equations [PDF]
arXiv, 2019 This course is intended as an introduction to the analysis of elliptic partial differential equations. The objective is to provide a large overview of the different aspects of elliptic partial differential equations and their modern treatment. Besides variational and Schauder methods we study the unique continuation property and the stability for ...

Advanced Optical Materials, EarlyView.This work demonstrates that wavelength selective reflection of circularly polarized light (CPL) of both handedness (right‐R or left‐L) can be achieved from self‐assembled cellulose nanocrystals (CNCs), breaking the inherent limitation of obtaining only L‐CPL reflection.
