Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

The Enantioselective Metabolism of p-Cymene in Rabbits.

open access: yesChemical and Pharmaceutical Bulletin, 1992
p-Cymene (1) was metabolized in rabbits and the following four optically active metabolites, 2-(p-tolyl)-1-propanol (3': R/S = 65:35), 2-(p-tolyl)propanoic acid (5': R/S = 0:100), p-(2-hydroxy-1-methylethyl)benzoic acid (6': R/S = 91:9) and p-(1-carboxyethyl)benzoic acid (8': R/S = 30:70), were isolated in addition to three optically inactive ...

Sprayable Polyolefin Sorbents Enabled by Bio‐Solvents for Large‐Scale Oil and Chemical Spill Recovery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sprayable POE‐based sorbent formulated with a green solvent blend of α‐pinene, D‐limonene, and p‐cymene enables rapid in situ film formation via solvent evaporation, allowing efficient pollutant capture. The system exhibits high oil uptake (37.3 g g−1) and effectively removes up to 60 mL of VLSFO under simulated marine spill conditions.

Rhodium‐Catalyzed Carbene Transfer to Isocyanides Using Zinc Carbenoids

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A diazo‐free rhodium‐catalyzed carbene transfer to isocyanides using zinc carbenoids generated from α‐acyloxy halides is reported. This mild protocol furnishes ketenimines that can either be hydrolyzed to amides or intercepted with trimethylsilyl azide or carboxylic acids to give tetrazoles and imides, respectively.

Essential Oil Polymorphism of Wild Growing Hungarian Thyme () Populations in the Carpathian Basin

open access: yesNatural Product Communications, 2010
The volatile oil compositions of Thymus pannonicus All. from nineteen different localities of Hungary were analyzed by GC/MS. The essential oil content of the Hungarian thyme samples varied between very low (0.14 mL/100 g DW) and fairly high (1.9 mL/100 ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...
