Analysis of self-similar solutions in Helmholtz equation
, 2007 In this thesis, we study the method of similarity solutions for partial differential equations. We provide several examples for each concept. Then, we investigate the existence of self-similar solutions, in general, and we apply the method for Helmholtz ...

Advanced Science, EarlyView.A Cu‐mediated Ni(OH)2 catalyst with orthogonal activity by precise valence engineering simultaneously accelerates rate‐determining aldehyde C─H activation in HMF oxidation and impedes O─H deprotonation in competing OER. This multi‐functional synergistic catalysis enables FDCA production at industrial‐level current densities without sacrificing FEFDCA ...

Impedance of Nonelectroneutral Solid Electrolyte Interphases With Nanopores: A Theoretical Model
Advanced Science, EarlyView.Physical modeling reveals that often‐neglected non‐electroneutrality and nanopores in the solid‐electrolyte interphase (SEI) govern the impedance behavior. Under nonreactive conditions, the low‐frequency constant‐phase element (CPE) phenomenon can be attributed to the nonelectroneutral local conditions in the SEI.

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications
Advanced Science, EarlyView.This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

V2CTx MXene as a Sacrificial Promoter for NiFe Catalyst for Anion Exchange Membrane Electrolyzers
Advanced Science, EarlyView.These findings demonstrate that V2CTx functions beyond passive conductive support as an active electronic participant whose structural legacy sustains durable performance even after vanadium leaching in Anion Exchange Membrane (AEM) Electrolysers. ABSTRACT Nickel‐iron layered double hydroxides (NiFe‐LDH) show excellent activity, their poor conductivity
