Mass Spectrometry Reviews, EarlyView., 2023 Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.

Nested subcritical flows within supercritical systems [PDF]
In supercritical systems the design inlet and outlet pressures are maintained above the thermaodynamic critical pressure P sub C. Designers rely on this simple rule of thumb to circumvent problems associated with a subcritical pressure regime nested ...

Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.

Cocoa waste valorization: a review and sustainability analysis of green technologies
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Cocoa residues – notably cocoa pod husks and cocoa bean shells – can be valorized for biocompound recovery, bioenergy production, and waste reduction. This review analyzed 1115 publications related to this field to identify key research trends. Interest is increasing in compounds such as theobromine, bioactive substances, adsorption processes,

Thermodynamic crossovers in supercritical fluids
Proceedings of the National Academy of SciencesCan liquid-like and gas-like states be distinguished beyond the critical point, where the liquid–gas phase transition no longer exists and conventionally only a single supercritical fluid phase is defined? Recent experiments and simulations report strong evidence of dynamical crossovers above the critical temperature and pressure.

Reaction Engineering of In Vitro Natural Product Biosynthesis: Challenges and Strategies
ChemBioChem, EarlyView.The yield and turnover of in vitro natural product biosynthesis, and even its feasibility, are determined by intermolecular interactions. Reaction engineering allows to improve the performance of such complex biocatalytic systems. Natural products are widely used as pharmaceuticals and agrochemicals, or as active ingredients in food and cosmetics ...
