Bimetallic Nanoparticles as Cocatalysts for Photocatalytic Hydrogen Production

open access: yesAdvanced Functional Materials, EarlyView.
Recent developments have introduced bimetallic nanoparticles as effective cocatalysts for photocatalytic systems. This review explores the rapidly expanding research on bimetallic cocatalysts for photocatalytic production of hydrogen, emphasizing the creation of carrier‐selective contacts, localized surface plasmon resonance effects, methodologies for ...

A method of moments to estimate bivariate survival functions: the copula approach

open access: yesStatistica, 2013
In this paper we discuss the problem on parametric and non parametric estimation of the distributions generated by the Marshall-Olkin copula. This copula comes from the Marshall-Olkin bivariate exponential distribution used in reliability analysis.

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

open access: yesAdvanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

On interpolation of operator, which is the sum of weighted Hardy-Littlewood and Cesaro mean operators

open access: yesResearches in Mathematics, 2019
It is proved that operators, which are the sum of weighted Hardy-Littlewood $\int\limits_0^1 f(xt) \psi(t) dt$ and Cesaro $\int\limits_0^1 f(\frac{x}{t}) t^{-n} \psi(t) dt$ mean operators, are limited on Lorentz spaces $\Lambda_{\varphi, a} (\mathbb{R})$,

Combinatorial Synthesis of Next Generation Water‐Soluble Quaternized N‐Halamine Oligomers with Long‐Lasting Antiviral Properties

open access: yesAdvanced Functional Materials, EarlyView.
A combinatorial library of dual‐functional antiviral oligomers incorporating N‐halamine and quaternary ammonium functionalities is developed for long‐lasting antiviral activity. The lead materials exhibit rapid and durable antiviral activity against SARS‐CoV‐2 variants and influenza H1N1, with 4 to 5 log reduction in viral copies at 5 mg mL−1 ...

Notes on Absolutely Continuous Functions of Several Variables

open access: yesReal Analysis Exchange, 2005
The paper contains a~variety of interesting observations about absolutely continuous functions of several variables. The point of departure is the theorem of \textit{J. Kauhanen, P. Koskela} and \textit{J. Malý} [Manuscr. Math. 100, No. 1, 87--101 (1999; Zbl 0976.26004)], which states that any function on a~domain \(\Omega\subset\mathbb R^ n\) whose ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced 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.

Absolutely Continuous Functions of Rado, Reichelderfer, and Malý

open access: yesJournal of Mathematical Analysis and Applications, 2000
The aim of the paper is to compare different definitions of absolute continuity and bounded variation for functions of \(n\)-variables. Given a symmetric convex set \(K\) with non-empty interior, let \({\mathcal K}\) be the class of all dilated and translated copies of \(K\) and let us say that a continuous function with compact support is \(K ...

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

open access: yesAdvanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.
