The Versatile Structural World of Methanedi‐ and Trisulfonic Acid and Their Salts

open access: yesChemistryOpen, Volume 15, Issue 7, July 2026.
The solid‐state structures of the CH4‐derived polysulfonic acids methanedisulfonic acid (MDSA) and methanetrisulfonic acid (MTSA) are presented for the first time. Additionally, a broad overview over possible MDS and MTS salts, containing mostly group I cations, is given and their solid‐state structures are analyzed, showing the structural versatility ...

Enhanced Biomethane Recovery From Source‐Separated Cow Urine via Co‐Digestion With Waste Paper

open access: yesGCB Bioenergy, Volume 18, Issue 7, July 2026.
This study outlines the experimental process where cow urine, collected from a dairy barn equipped with a source‐separating manure system, and waste paper are loaded into bioreactors (CU0–CU50) at varying ratios to analyze the biogas yield. The analytical results highlight that this collection system significantly enhances biogas and biomethane ...

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

open access: yesChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...

From Citrus to Cymene: Understanding the Hydrothermal Conversion of Limonene

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
When life gives you limonene… Hydrothermal conversion and pyrolysis of limonene give two distinct sets of products, arising from differing reaction cascades. While p‐cymene dominates in the presence of water, indicative of an isomerisation/aromatisation pathway, pyrolysis favours cracking and loss of carbon affording an m‐xylene rich aromatic mix.

ZnMgO/Se Thin Film Photovoltaic Devices With Graphene/Silver Nanowire Stacked Flexible Transparent Conducting Electrodes

open access: yesphysica status solidi (a), Volume 223, Issue 11, 10 June 2026.
The graphene/AgNW transparent conductive electrode (TCE) was applied to ZnMgO/Se photovoltaic devices. Device with sol–gel ZnO layers that protected from sputtering damage clearly exhibited photovoltaic effect. As compared with devices using conventional indium tin oxide (ITO) TCEs, photovoltaic devices containing graphene/AgNW TCEs showed a 56 ...
