Operator method for the perturbative solution of ordinary differential equations
Computers & Mathematics with Applications, 1978 Abstract We adapt the Feynman operator calculus to the Lie operators connected with the solution of ordinary, coupled, first order differential equations, particularly those arising from non-linear oscillations or from interactions between modes. Combining this calculus with the method of averaging we obtain approximate solutions which are algebraic ...

Advanced Engineering Materials, EarlyView.The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Advanced Functional Materials, EarlyView.Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Chaotic perturbations of solitons in complex conformable Maccari system
AIMS MathematicsIn this research work, we use the generalized Bernoulli equation method (gBEM) to investigate the chaotic nature of solitons in complex structured conformable coupled Maccari system (CCMS) which is a fractional generalization of a nonlinear model coupled

Singular perturbations of ordinary differential equations in Colombeau spaces
Publications de l'Institut Mathematique, Beograd, 2000 A system of the form \[ y'(t)=f(t,y(t))+G(t),\quad y(-1)=y_0 \] is considered. \(G\) is a generalized function, for example \(G=\delta^{(\alpha)}\) and \(f\) is a smooth, not always the globally Lipschitz, vector function. The authors analyze an appropriate, approximated, family of systems in the framework of Colombeau generalized function algebra.

Advanced Functional Materials, EarlyView.Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition
