Molecular and supramolecular chirality: R2PI spectroscopy as a tool for the gas-phase recognition of chiral systems of biological interest. [PDF]

open access: yes, 2009
A review. In life sciences, diastereomeric chiral mol./chiral receptor complexes are held together by a different combination of intermol. forces and are therefore endowed with different stability and reactivity. Detn.

Recent Trends in Metabolomics by NMR Spectroscopy

open access: yesAngewandte Chemie, EarlyView.
AI tools were applied to analyze more than 5 000 publications indexed in Scopus (2018–2025), identifying key trends and research directions in NMR‐based metabolomics. The artificial intelligence‐assisted workflow classified papers into six main fields of application, human health, food and nutrition, veterinary science, plants, environment, and ...

Synthesis Of Biodegradable Star-Shaped Polymers Using Bio-Based Polyols Via Ring-Opening Polymerization Of Β-Butyrolactone With Amido-Oxazolinate Zinc Catalysts [PDF]

open access: yes, 2019
A new series of star-shaped and highly branched poly(β-hydroxybutyrates) (PHBs) with a distinct structure was synthesized by ring-opening polymerization (ROP) of β-butyrolactone (BBL) with amido-oxazolinate zinc catalysts.

A hypothetical mechanism capable to reflect the features of the mitochondrial permeability transition pore channel

open access: yesAdvances in Redox Research
Mitochondrial permeability transition pore (mPTP) channel plays a central role in cell death because it mediates the effect of a sudden large opening of the inner mitochondrial membrane.
