Chemically Fueled Systems Chemistry Across Length Scales
Advanced Functional Materials, EarlyView.Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Controllability of neutral functional differential equations with infinite delay
Acta Mathematica Scientia, 2011 In this article, we give sufficient conditions for controllability of some partial neutral functional differential equations with infinite delay. We suppose that the linear part is not necessarily densely defined but satisfies the resolvent estimates of the Hille-Yosida theorem. The results are obtained using the integrated semigroups theory.

Advanced Functional Materials, EarlyView.This work presents a ligand‐pairing strategy that reconstructs lead sulfide quantum dot surfaces for efficient short‐wave infrared optoelectronics. A low‐reactivity thiourea precursor combined with hydrobromic acid enables monodisperse and fully passivated quantum dots.

New criteria for oscillation of nonlinear neutral differential equations
Advances in Difference Equations, 2019 The aim of this work is to offer sufficient conditions for the oscillation of neutral differential equation second order (r(t)[(y(t)+p(t)y(τ(t)))′]γ)′+f(t,y(σ(t)))=0, $$ \bigl( r ( t ) \bigl[ \bigl( y ( t ) +p ( t ) y \bigl( \tau ( t ) \bigr) \bigr ...

Oscillation of First Order Neutral Delay Differential Equations
Journal of Mathematical Analysis and Applications, 1995 First order neutral delay differential equations with single delays as well as with several delays are studied. Some necessary and sufficient conditions for oscillation are proved by using the existence of real roots of the relevant characteristic equation. Some sufficient conditions for oscillation are obtained.
