A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution
Advanced Materials Interfaces, EarlyView.ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Advanced Materials Technologies, EarlyView.High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

On the covering dimension of the set of solutions of some nonlinear equations [PDF]
, 1986 We prove an abstract theorem whose sole hypothesis is that the degree of a certain map is nonzero and whose parametric equations are studied using cohomological mconclusions imply sharp, multidimensional continuation results.

Monotone solutions of a class of nonlinear difference equations
Computers & Mathematics with Applications, 1994 The authors prove some comparison theorems for the existence of a positive nondecreasing solution of the nonlinear difference equation (1) \(\Delta (p_{k - 1} (\Delta x_{k - 1})^ \sigma) + q_ k x^ \sigma_ k = 0\), \(k = 1,2, \dots\) where \(\sigma > 0\) and \(\{p_ k\}^ \infty_ 0\) is a positive sequence.

Positive Solutions for Nonlinear Integro-Differential Equations of Mixed Type in Banach Spaces
Abstract and Applied Analysis, 2013 We establish some new existence theorems on the positive solutions for nonlinear integro-differential equations which do not possess any monotone properties in ordered Banach spaces by means of Banach contraction mapping principle and cone theory based ...
