Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

Advanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...

Boundary value problems and differentiability for neutral functional differential equations

, 1986
This paper is concerned with the existence of solutions of a boundary value problem for neutral differential equations. Specifically, we consider the problem \[ (*)\quad (d/dt)(Dx_ t-g(t,x_ t))=Lx_ t+f(t,x_ t),t\in (0,\tau],Mx_ 0+\int^{\tau}_{0}[d\mu (t)]x_ t=\gamma, \] where M and \(\mu\) (t) are linear operators and \(\gamma\) is a fixed element of a

Disordered Carbon Shells Enable Shape Dependent Fluorescence Enhancement in Nanodiamond Quantum Sensors Revealed by Correlative TEM–Fluorescence Microscopy

Advanced Functional Materials, EarlyView.
Molten KNO2 treatment induces a lowrefractive index disordered carbon shell on fluorescent nanodiamonds, enhancing fluorescence emission while preserving spin coherence. Machine learningassisted correlative TEMPL enables direct single‐particle resolution of this enhancement relative to air‐oxidized nanodiamonds of similar morphology, establishing a ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Existence of positive periodic solutions for neutral Lienard differential equations with a singularity

Electronic Journal of Differential Equations, 2015
By applying Mawhin's continuation theorem, we study the existence of positive periodic solutions for a second-order neutral functional differential equation $$ ((x(t)-cx(t-\sigma)))''+f(x(t)) x'(t)+g(t,x(t-\delta))=e(t), $$ where g has a strong ...

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

Advanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Weighted pseudo almost automorphic solutions to functional differential equations with infinite delay

Electronic Journal of Differential Equations, 2016
In this article, we first establish some results on composition of Stepanov-like weighted pseudo almost automorphic functions so called class r and class infinity under a uniform continuity condition with respect to L^p-norm.
