Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Effect of bio-engineering on size, shape, composition and rigidity of bacterial microcompartments [PDF]

open access: yes, 2016
Bacterial microcompartments (BMCs) are proteinaceous organelles that are found in a broad range of bacteria and are composed of an outer shell that encases an enzyme cargo representing a specific metabolic process.

Redox‐Responsive Mitochondrial Delivery from Functionalized Vascular Stent Surfaces

open access: yesAdvanced NanoBiomed Research, Volume 6, Issue 3, March 2026.
A redox‐responsive stent surface is engineered to deliver functional mitochondria in response to oxidative stress. Upon exposure to reactive oxygen species, grafted mitochondria are released, internalized by vascular cells, and restore mitochondrial function under stress.

Segregated water observed in a putative fish embryo cryopreservative [PDF]

open access: yes, 2016
Development of new cryopreservation strategies has major potential in medicine and agriculture and is critical to the conservation of endangered species that currently cannot be preserved. A critical property of any potential cryopreservative solution is

Industrial strategies to minimize glycerol formation in ethanol fermentation by conventional Saccharomyces cerevisiae

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 1006-1020, March/April 2026.
Abstract Industrial ethanol production faces the challenge of balancing metabolic efficiency with the minimization of byproducts such as glycerol, whose formation is intensified by osmotic, thermal, oxidative, and nutritional stresses. In the literature, two main approaches stand out for modulating its synthesis: the use of genetically modified strains

Regulation of fucose and 1,2-propanediol utilization by Salmonella enterica serovar Typhimurium

open access: yesFrontiers in Microbiology, 2015
After ingestion, Salmonella enterica serovar Typhimurium (S. Typhimurium) encounters a densely populated, competitive environment in the gastrointestinal tract. To escape nutrient limitation caused by the intestinal microbiota, this pathogen has acquired

Cobalamin-dependent 1,2-propanediol utilization by Salmonella typhimurium [PDF]

open access: yesJournal of General Microbiology, 1990
The enteric bacterium Salmonella typhimurium utilizes 1,2-propanediol as a sole carbon and energy source during aerobic growth, but only when the cells are also provided with cobalamin as a nutritional supplement. This metabolism is mediated by the cobalamin-dependent propanediol dehydratase enzyme pathway.
