Infinite Functional Versatility, Formidable Limits: Evaluating Gallium‐Based Liquid Metals in Rechargeable Batteries

Carbon Energy, EarlyView.
Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

Evaluation of Oxalic Acid treatments against the Mite Varroa destructor and Secondary Effects on Honey Bees Apis mellifera

Journal of Arthropod-Borne Diseases, 2016
Background: The Varroa destructor varroasis is a very serious parasite of honeybee Apis mellifera. The objective of this study was to evaluate the effectiveness of Varroa treatment using organic acid (oxalic acid) in Algeria identify­ing its side effects

Field Evaluation of Oxalic Acid Vaporisation for Varroa Mite (Varroa destructor) Control in European Honey Bees (Apis mellifera) Colonies

Journal of Apicultural Science
Varroa mites (Varroa destructor) are a major threat to honey bee health globally. Oxalic acid has gained popularity among beekeepers as a potential varroa mite control agent.

Catalyst‐Free Selective Reduction of Nitrogen Dioxide to Nitric Oxide

Chemistry – A European Journal, EarlyView.
Common main group reductants selectively convert nitrogen dioxide to nitric oxide in a catalyst‐free manner. Computational studies suggest divergent reaction pathways depending on the reductant employed. Where boranes and silanes proceed via a two‐electron process, and hydrogen surrogates undergo stepwise one‐electron processes.

Oxidation of Allylic Alcohols by Manganese Oxides: Elucidating the Influences of MnOx Structure and Mn Oxidation State on Reactivity

Chemistry – A European Journal, EarlyView.
Manganese oxides (MnOX) of different structures and with different Mn oxidation states exhibit significant variation in their reactivity toward the oxidation of allylic alcohols. Using two allylic alcohol model substrates, we demonstrate the relationship between activity and MnOX structure, Mn4+ content and incorporated secondary cations.

Determination of Oxalic Acid in Foods

Journal of AOAC INTERNATIONAL, 1973
Abstract Two methods for the determination of oxalic acid were collaboratively studied. In both methods, the oxalic acid in spiked and unspiked spinach is precipitated as calcium oxalate from a buffered (pH 4.0–4.5) solution. The precipitate is separated from the solution by centrifuging 15 min at 1700 rpm.

Carbon monoxide adsorption on NaY zeolite and impregnated with 5% niobium: Characteristics and fixed‐bed study

The Canadian Journal of Chemical Engineering, EarlyView.
Schematic of the CO adsorption process in a fixed‐bed column containing pure NaY zeolite and Nb‐modified NaY (NaY–5%Nb). On the left, breakthrough curves and temperature profiles highlight the dynamic performance and thermal effects during CO adsorption.

Adjuvants to improve efficacy of miticides in managed honey bee (Apis mellifera) colonies to control Varroa destructor.

PLoS ONE
Beekeepers must manage Varroa destructor mites to maintain colony health. Large-scale beekeepers often use chemical treatments (miticides) to manage this pest.

Removal of Decontaminating Agent from Aqueous Solution Using Microporous and Mesoporous Materials: Activated Carbon as an Effective Adsorbent

Adsorption Science & Technology, 2008
Wastewater from nuclear plants contains oxalic acid, a chelating compound used to remove surface activity. This forms complexes with radioactive cations, thereby impeding their removal by conventional techniques. In this study, oxalic acid was removed by

Crystallization of Cathode Active Material Precursors from Tartaric Acid Solution

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
This work investigates a novel approach for closing the gap between recycling and production of lithium‐ion battery cathode material. The new concept is based on antisolvent crystallization of metal carboxylates, which can be directly used as precursors in production of cathode material.
