Pt/TiO2 Prepared by Mechanochemistry Boosts Photocatalytic Production of Hydrogen

ChemCatChem, EarlyView.
Ball milling enables the rapid synthesis of a Pt/TiO₂ photocatalyst with atomically dispersed Pt, outperforming a conventional Pt‐cluster catalyst (1.3× higher H2 evolution from ethanol). Enhanced activity is attributed to single‐atom stabilization and suppressed surface restructuring, promoting efficient charge separation via Schottky barrier ...

H2 Production from Ammonia Borane: Integrating Experiments, Computational Fluid Dynamics, and Statistical Analysis for Predicting and Optimizing Process and Reactor Design

ChemCatChem, EarlyView.
Ammonia borane is considered a great hydrogen carrier, and when hydrolyzed, it can generate 3 moles of H2. This study highlights the combination of experimental and computational work, such as modeling and statistical analysis, that enables future experimentation by focusing on the parameter with the most profound effect on maximum H2 yield.

Screening of parameters and optimization of nickel extraction by green emulsion liquid membrane using statistical experimental design

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study focuses on the extraction of nickel ions from an aqueous solution using a green emulsion liquid membrane (GELM). Its primary objective is to choose between corn oil and sunflower oil as a solvent in GELM and compare their performance with a kerosene‐based emulsion liquid membrane (ELM).

Controlling polymer addition flowrate to improve the flocculation of kaolinite suspensions as models for oil sands mature fine tailings

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Oil sands exploration generates large volumes of mature fine tailings—mixtures of clays, water, and residual bitumen—that remain stable even after settling in tailings ponds for many years. Commonly used flocculants, such as neutral and anionic polyacrylamides, destabilize the colloidal interactions between the clay particles, but ...

Employment Negotiations With an Algorithm? How AI as Negotiation Counterpart Would Affect Negotiators' Trust and Subjective Value Expectations

Conflict Resolution Quarterly, EarlyView.
ABSTRACT Artificial intelligence (AI) offers manifold ways to improve organizational recruiting and conflict resolution due to high processing power and low subjective biases. Additionally to AI applications approaching and selecting job applicants, AI usage might also be promising in employment negotiations as the final step of recruitment.

Purification of Li2CO3 Obtained through Pyrometallurgical Treatment of NMC Black Mass from Electric Vehicle Batteries

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Lithium carbonate (Li2CO3) obtained from the black mass of recycled lithium batteries is dissolved in water under controlled conditions to remove lithium fluoride (LiF), which is present at a concentration of 3.08 % by weight. The dissolution is carried out at temperatures below 10 °C, and it has been demonstrated that lower temperatures result in ...

TEMPO‐Mediated Paired Electrosynthesis of Ethylene Glycol from Formaldehyde and Methanol at High Current Densities

ChemSusChem, EarlyView.
A high‐yield paired electrosynthesis of ethylene glycol from formaldehyde and methanol at current densities up to 350 mA cm−2 is demonstrated. The presented method utilizes inexpensive graphite electrodes in either batch or flow cell and 2,2,6,6‐tetramethylpiperidin‐1‐yl)oxyl (TEMPO) as a redox mediator.
