Evidence for structural crossover in the supercritical state
, 2013 The state of matter above the critical point is terra incognita, and is loosely discussed as a physically homogeneous flowing state where no differences can be made between a liquid and a gas and where properties undergo no marked or distinct changes ...

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.

Cannabigerol Extraction from a Cannabis Cultivar Using a Supercritical Carbon Dioxide Process
Chemical Engineering &Technology, EarlyView.The aim of this work was to assess for the first time the supercritical fluid extraction (SFE) process feasibility to obtain a CBG‐rich extract from Cannabis. Extraction experiments highlighted that CBG can be properly extracted at 18 MPa and 40 °C and the extraction plant scheme affected CBG recovery and purity.

Chemistry – A European Journal, EarlyView.Chiral COSAN Nanocatalysts: Enantiopure silica COSAN‐Hybrid nanohelices have been prepared by electrostatic co‐assembly of achiral COSAN anions and silica hybrid nanohelices. Their optical activity was confirmed by CD and ROA measurements. These COSAN‐Hybrids are efficient and recoverable catalysts in the photooxidative kinetic resolution of aromatic ...

Chemie Ingenieur Technik, EarlyView.A methanol mini‐plant and its digital twin were developed to study flexible feedstocks, reactant recycling, and product condensation. Experimental results show good agreement with simulations, allowing systematic investigation of process parameters. Tests with biomass‐derived syngas demonstrated the feasibility of industrial COx sources.

Corn cob pyrolysis: A systematic literature review of methods and applications
The Canadian Journal of Chemical Engineering, EarlyView.Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.
