Oxygen Vacancy-Mediated ZnO Nanoparticle Photocatalyst for Degradation of Methylene Blue

Applied Sciences, 2018
ZnO nanoparticles (NPs) are synthesized by deoxidizing ZnO powder in a vacuum drying process. This process reduces the size of the NPs and increases the concentration of oxygen vacancies on their surfaces.

Variation of magnetic properties of Sr2FeMoO6 due to oxygen vacancies [PDF]

, 2018
Oxygen vacancies can be of utmost importance for improving or deteriorating physical properties of oxide materials. Here, we studied from first-principles the electronic and magnetic properties of oxygen vacancies in the double perovskite Sr2FeMoO6 (SFMO)

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.

Facile synthesis of Sb2WO6 with gradient oxygen vacancies for high photocatalytic activity

AIP Advances
The Sb2WO6 photocatalyst is synthesized by introducing oxygen vacancies through acetylene annealing. The number of oxygen vacancies can be adjusted by varying the annealing duration. Oxygen vacancy defects in Sb2WO6 change the surface chemical properties,

The Establishment-Level Behavior of Vacancies and Hiring [PDF]

This paper is the first to study vacancies, hires, and vacancy yields at the establishment level in the Job Openings and Labor Turnover Survey, a large sample of U.S. employers. To interpret the data, we develop a simple model that identifies the flow of

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

The Distribution and Determinants of Job Vacancies: Evidence From the 2001 Employers Skill Survey [PDF]

Despite their obvious importance for employment determination and the operation of labour markets, little is known about the distribution, nature or determinants of job vacancies.

Strengthening the Synergy between Oxygen Vacancies in Electrocatalysts for Efficient Glycerol Electrooxidation

Defect-engineered bimetallic oxides exhibit high potential for the electrolysis of small organic molecules. However, the ambiguity in the relationship between the defect density and electrocatalytic performance makes it challenging to control the final ...

Injection of vacancies at metal grain boundaries during the oxidation of nickel [PDF]

, 2004
Nickel foils have been oxidised at 1000 °C on one side only in laboratory air, the other side being protected from oxidation by a reducing atmosphere.
