Uniqueness of Supramolecular Systems

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
Thanks to the variety of classes of supramolecular systems, they have been widely used in various applications. For example, in sensing devices, catalysis, and biomedicine. An example of a conventional photovoltaic material converted into electrical energy. Selective UV or NIR absorbers are required to produce materials with low or no coloration.

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...

Comparative Computational Studies of 3,4-Dihydro-2,6-diaryl-4-oxo-pyrimidine-5-carbonitrile Derivatives as Potential Antinociceptive Agents

Molecules, 2012
In this study, the antinociceptive properties of 3,4-dihydro-2,6-diaryl-4-oxo-pyrimidine-5-carbonitrile derivatives 5a–i at doses of 25 and 50 mg/kg were evaluated in mice, using the abdominal constriction test.

The Relationship Between Catalyst and Solvent in Hydrogenation via Condensed Phase Heterogeneous Catalysis

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Heterogeneous catalysis has historically been developed in the gas phase, however, we have found it pertinent to highlight solvent effects that must be accounted for in liquid environments. Condensed phase catalysis, like that in biomass, petroleum and the conversion of CO2, stands to benefit from the typically overlooked discussion regarding the ...

Synthesis of Isoxazolo[4,5‐D]Pyrimidinones, and their Isomerization into Oxazolo[4,5‐D]Pyrimidinones on Flash Vacuum Pyrolysis

Bulletin des Sociétés Chimiques Belges, 1994
AbstractA series of new 3‐phenylisoxazolo[4,5‐d]pyrimidinones 5a‐d were prepared from 5‐aminoisoxazole‐4‐carboxylic acid esters. Upon flash‐vacuum pyrolysis, these heterocycles are isomerized into hitherto unreported 2‐phényloxazolo[4,5‐d] ‐pyrimidinones 8a‐d.
