Semi‐Artificial Photosynthesis Enables Light‐Driven Biomanufacturing in Non‐Photosynthetic Bacteria [PDF]
Advanced scienceA non‐invasive strategy exploits endogenous H2S metabolism in B. subtilis to drive in situ CdS biomineralization, enabling tight bio‐abiotic contact without genetic modification. Light harvested by the biomineralized nanoparticles powers NADPH regeneration, elevating 2’‐fucosyllactose and surfactin titres two‐ to three‐fold.

Gaseous mediators (H2S, NO and CO) a new approach in gastrointestinal protection
Mexican Journal of Medical Research ICSA, 2023 Gastrointestinal damage is generated by a wide range of harmful agents, and is the result of the activation of inflammatory, oxidant and cytotoxic mechanisms, that together overwhelm the “mucosa defense” of the gastrointestinal (GI) tract.

The rotational excitation of H2 by H2 [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We present rate coefficients for rotational transitions induced in collisions between H2 molecules. Rotational levels J ≤ 8 and kinetic temperatures T ≤ 1000 K are considered. The interaction potential computed by Schwenke has been used, together with the quantal coupled channels method of calculating the cross-sections.
