New Stationary Solutions of the Nonlinear Drift Wave Equation
, 1995 "A new type of nonlinear wave modes which occur as the electrostatic drift waves in an inhomogeneous magnetized plasma is presented. The existence of a new type of spiky solitary wave and an explosive mode with the negative potential are predicted as ...

Relativistic Wave Equation for Radiant Electron [PDF]
, 2018 In this article a relativistic wave equation for the accelerated radiant electron, indepen- dent of Dirac formalism, based on the concept of radiation of classical electrodynamics is proposed. This work describes the solution for the free electron case,

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

The numerical solution of the wave equation at the first time step
, 1981 Superimposing a uniformgrid on the space variable in the simple wave equation, for which boundary conditions, initial displacement and initial velocity are specified, leads to the numerical solution of a system of second order ordinary differential ...

Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells
Advanced Functional Materials, EarlyView.Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework
Advanced Functional Materials, EarlyView.The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Advanced Functional Materials, EarlyView.Moiré band engineering in graphene/hexagonal boron nitride–based superlattices unlocks van Hove singularities (VHSs) for terahertz (THz) optoelectronics. Tuning the Fermi level near these singularities, associated with secondary neutrality points (SNPs), enhances the photothermoelectric response.
