Precipitation of niobic acid from potassium niobate in sulphuric acid solution: A route to niobium oxide

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4419-4434, August 2026.
Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5). Thermodynamic modelling with PHREEQC and

Just Transition Toward Clean Energy Access With Focus on Lead‐Based Perovskite Solar Cell Technology: Lessons, Experiences, and Future Perspectives

Global Challenges, Volume 10, Issue 8, August 2026.
To intentionally mitigate energy poverty in underserved communities, advanced perovskite energy technologies such as lead‐based perovskite solar cells are necessary. However, in future deployment of these materials, energy justice, equity, inclusivity and environmental sustainability must be taken into account.

The use of activated carbon derived from spent coffee grounds as a reusable, sustainable, and effective solution for the removal of butylparaben from water

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1547-1558, August 2026.
Abstract BACKGROUND Parabens, including butylparaben (BP), are widely used as antimicrobial preservatives in food, cosmetics, and pharmaceuticals, yet are poorly removed by conventional water treatment processes and pose potential risks to aquatic life and human health.

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Hybrid Dynamic–Covalent PEG Hydrogels With Enhanced Stability for Photothermally Triggered Pulsatile Drug Delivery

Macromolecular Bioscience, Volume 26, Issue 8, August 2026.
Hydrogels with dynamic covalent crosslinks enable stimuli‐responsive drug delivery but often degrade rapidly. Here, PEG hydrogels combining reversible thiol‐conjugate and stable thiol‐maleimide crosslinks showed enhanced stability and prolonged lifetime.
