Novel Electrochemical Treatment of Spent Caustic from the Hydrocarbon Industry Using Ti/BDD

International Journal of Photoenergy, 2015
During the crude oil refining process, NaOH solutions are used to remove H2S, H2Saq, and sulfur compounds from different hydrocarbon streams. The residues obtained are called “spent caustics.” These residues can be mixed with those obtained in other ...

Gold-Indium Electrocatalysts for the Selective Oxidation of Glycerol Coupled with CO₂ Reduction. [PDF]

ChemSusChem
A new gold–indium alloy electrocatalyst for glycerol oxidation has been synthesized. This material has its manufacturing cost reduced by 28% while reducing the onset potential by 210 mV. The catalyst has been applied in a flow cell electrolysis coupled with CO2 reduction achieving faradaic efficiencies over 90% working at a current density of 200 mA cm−

Role of Metal Contacts on Halide Perovskite Memristors

Advanced Functional Materials, Volume 33, Issue 47, November 16, 2023., 2023
Halide perovskites are electronic/ionic conductors used as resistive memories. The role of the metal contacts is unveiled by using metals with different reactivities. It is shown that metals need to be oxidized electrochemically in situ and this oxidized species can follow the applied electrical field to generate the conductive filaments.

Molecular One‐ and Two‐Qubit Systems with Very Long Coherence Times

Advanced Materials, Volume 35, Issue 38, September 21, 2023., 2023
Very long coherence times of up to 140 µs are reported in perchlorotriphenylmethyl mono‐ and diradicals, strongly exceeding previous values. Furthermore, two‐spin coherent manipulations are reported in the biradical systems, as a basic quantum gate operation.

Production of selenium nanoparticles occurs through an interconnected pathway of sulphur metabolism and oxidative stress response in Pseudomonas putida KT2440

Microbial Biotechnology, Volume 16, Issue 5, Page 931-946, May 2023., 2023
The soil bacterium Pseudomonas putida KT2440 is able to reduce selenite to form nanoparticles of elemental selenium. In this work we combine a transposition screening with transcriptomics and biochemical assays to shed light into this process of biotechnological interest.

Facile preparation of electrodes based on WO3 nanostructures modified with C and S used as anode materials for Li‐ion batteries

Journal of the American Ceramic Society, Volume 106, Issue 4, Page 2550-2566, April 2023., 2023
Abstract An appropriate morphological and structure matrix configuration where lithium ions could insert and de‐insert is essential for lithium‐ion batteries (LiB). Tungsten oxides (WO3) are especially attractive materials for this aim. In this research, the effects of the morphology and composition of WO3 nanostructures on the charge/discharge ...

Anti‐corrosive additives for alkaline electrolyte in Al‐air batteries: NH4VO3 and polyoxometalates

Electrochemical Science Advances, Volume 2, Issue 4, August 2022., 2022
NH4VO3 in alkaline electrolytes form a protective polymeric layer of tetrahedric V+5O4 species over Al5052, Al6062, and Al7475 alloys that inhibits corrosion. Combination with carboxymethyl cellulose forms a more stable layer that makes it promising for application in aluminum‐air batteries.

Requirements for Beneficial Electrochemical Restructuring: A Model Study on a Cobalt Oxide in Selected Electrolytes

Advanced Energy Materials, Volume 11, Issue 36, September 23, 2021., 2021
The requirements of beneficial material restructuring into a high‐performance oxygen evolution reaction (OER) electrocatalyst are investigated. The nature of the anions in the electrolyte directly affects the restructuring kinetics. Only carbonate can activate the catalytic current, forming a final material with adequate local structure, high Co ...
