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

ChemSusChem, 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 ...

Rewiring nutrition: Chemical insights into the physiological and microbiological roles of food's microconstituents

Food Biomacromolecules, EarlyView.
Bidirectional interactions between food‐derived sensory compounds, gut sensing and microbiota, host physiological feedback, and metabolite production within the food matrix collectively shape sensory perception, microbial dynamics, and metabolic health.

Supercritical Fluid Chromatography

International Journal of Advanced Research in Science, Communication and Technology, 2023
History of Supercritical Fluid Chromatography In 1822, the French physicist Charles Cannard de La Tour placed a liquid and a flint ball in a Papin rifle pressure vessel and heated the liquid with a sealed cannon. 1) When the container was shaken, the bullet broke through the air-liquid interface, and the sound of the bullet scattering was heard.

Lycopene‐rich food biomolecules from tomato processing waste: Green recovery, biopolymer‐based stabilisation, functional food applications and health relevance

Food Biomacromolecules, EarlyView.
Abstract Tomato processing waste, particularly peel and pomace, is a sustainable and low‐cost source of lycopene‐rich food biomolecules. Lycopene, a lipophilic carotenoid with an extended conjugated structure, provides intense red colour, antioxidant potential and functional value to tomato‐derived ingredients.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
