Oxetanes: Recent Advances in Synthesis, Reactivity and Medicinal Chemistry [PDF]

, 2016
The 4-membered oxetane ring has been increasingly exploited for its behaviors, i.e. influence on physicochemical properties as a stable motif in medicinal chemistry, and propensity to undergo ring opening reactions as a synthetic intermediate.

Resilience of floral scent emission after florivory

Plant Biology, EarlyView.
Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Silver and platinum-catalysed addition of O–H and N–H bonds to allenes [PDF]

, 2014
Transition-metal catalysed nucleophile addition to allenes is a very powerful tool for the synthesis of functionalised molecules containing heteroatoms, heterocycles in the intramolecular version, or allyl derivatives in the intermolecular version.

Electronic Smoking Devices Among University Students: Usage Patterns and Chemical Composition of Inhaled Substances

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT This study investigated the prevalence of electronic smoking device (ESD) use and its associated behavioural and chemical risks among university students in Bahia, Brazil. A cross‐sectional survey was conducted with 355 students from public and private institutions through an online questionnaire between April and May 2023. Among participants,

Development of fast switching photochromic coatings on transparent plastics and glass [PDF]

, 1999
A new photochromic organic-inorganic nanocomposite (Nanomer(R)) coating system has been developed. It is based on an epoxysilane as network former, an organic bisepoxide as spacer, an organic amine as thermal cross-linker and surface modified SiO2 ...

Selective Oxygenation of 3,4‐Dihydro‐2H‐Pyran to 5,6‐Dihydro‐2H‐Pyran‐2‐One With Pd/C Catalyst and Molecular Oxygen

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
Selective oxygenation: The oxidation of 3,4‐dihydro‐2H‐pyran, which can be produced from lignocellulose‐derived furfural, was investigated with various catalysts using O2 as an oxidant in a H2O solvent. 5,6‐dihydro‐2H‐pyran‐2‐one, a value‐added product, was obtained in 52% yield with reusable Pd/C catalyst.

Identification of Metabolites of the Dietary Supplement Ingredient 5α‐Hydroxy‐Laxogenin

Drug Testing and Analysis, Volume 18, Issue 4, Page 483-489, April 2026.
The biotransformation of the dietary supplement ingredient 5α‐hydroxy‐laxogenin was investigated using human HepG2 cells, the rat and in silico using the online software Next‐gen E‐Resource for Drug Discovery (NERDD). We identified five metabolites generated by the human HepG2 cells of which three and an additional mono‐hydroxylated metabolite were ...

Dual Antimicrobial–Antioxidant Postbiotics From Lactiplantibacillus plantarum for Clean‐Label Meat Preservation

eFood, Volume 7, Issue 2, April 2026.
The postbiotics, which possess both antimicrobial and antioxidant activities, are derived from Lactiplantibacillus plantarum strains, revealing the presence of bioactive compounds. Functional assays showed strong antioxidant activity and strain‐specific antimicrobial effects. When applied to pork, these postbiotics significantly reduced microbial loads,

Transient Brewster angle reflectometry of spiropyran monolayers [PDF]

, 2010
Brewster angle reflectometry has been developed as a tool for determining the absorbance and refractive index changes in molecular monolayers containing spiropyran. The method is sensitive to changes in both the real and imaginary parts of the refractive
