Who Lives in a Tin Can Under the (Ultrasonic) Sea: Sponges Made From Perfluoropyridine‐Derived Thiol‐Ene Polymerizations

open access: yesJournal of Polymer Science, EarlyView.
Tandem mechanochemical‐sonochemical for the strategic synthesis for 2,4,6‐trisubstituted derivatives of perfluoropyridine as bio‐based prepolymer materials. ABSTRACT Substitution of perfluoropyridine (PFP) in the 4‐position through an SNAr reaction is facile through mechanochemical methods, with yields in excess of 99% and short reaction times on a ...

Activation of Cyanate Anions by Phosphine Radical Cations Enables Formal Hydrocarbamoylation of Alkenes

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
A photocatalytic formal hydrocarbamoylation reaction that employs a cyanate anion as the C1 source and provides N‐acyl iminophosphorane products from activated alkenes is described. Mechanistic investigations suggest generation of a phosphoranyl radical by addition of the cyanate anion to a phosphine radical cation, which enables the delivery of the ...

Evidence of racial differences in peripheral blood pressure, central haemodynamics and arterial stiffness between young Black and White women

open access: yesExperimental Physiology, EarlyView.
Abstract Hypertension diagnosed via peripheral (brachial) blood pressure (pBP) is a strong independent predictor of overt cardiovascular disease (CVD). However, central (aortic) blood pressure (cBP), which is influenced by arterial stiffness, may be more strongly associated with CVD risk. Young Black women (BLW) demonstrate higher pBP than White women (

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...

Rearrangement of o-Nitrobenzaldehyde in the Hantzsch Reaction

open access: yesMolecules, 2001
The reaction of 5-hydroxy-2-nitrobenzaldehyde with ethyl acetoacetate in ammonia gave the two expected isomeric 1,4- and 1,2-dihydropyridines resulting from the normal Hantzsch reaction.

Synthesis of Quinazoline and Quinazolinone Derivatives via Ligand-Promoted Ruthenium-Catalyzed Dehydrogenative and Deaminative Coupling Reaction of 2-Aminophenyl Ketones and 2-Aminobenzamides with Amines [PDF]

open access: yes, 2019
The in situ formed ruthenium catalytic system ([Ru]/L) was found to be highly selective for the dehydrogenative coupling reaction of 2-aminophenyl ketones with amines to form quinazoline products.

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

From CO2 to C1 Liquid Fuels: Molecular Electrochemical Production of Formic Acid and Methanol

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Sustainable transformation of CO2 into formic acid and methanol is key to circular carbon economies and sustainable energy. These liquid C1 products are high in energy density, easy to store, and serve as hydrogen carriers and feedstocks. Electrochemical CO2 reduction provides a promising route for carbon recycling and renewable energy integration ...
