A pH-enhanced resolution in benchtop NMR spectroscopy

open access: yesThe Analyst
An alternative to serial NMR measurement on a benchtop machine exploits a pH gradient along the NMR tube and mechanical sample shifting. This approach allows one to detect and characterize “pH-sensitive” peaks.

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

open access: yesMacromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.

Comparison of different solvent suppression techniques for polymer characterization with a 90 MHz benchtop spectrometer

open access: yesJournal of Magnetic Resonance Open
In NMR spectroscopy, samples are usually dissolved in deuterated solvents to avoid overlap of small analyte signals with large, protonated solvent signals.

Analgesic effects of platelet‐rich fibrin (PRF): A systematic review

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Platelet‐rich fibrin (PRF), a second‐generation autologous platelet concentrate, has gained significant interest for its anti‐inflammatory and regenerative characteristics. While its role in tissue healing is well‐recognized, the analgesic potential of PRF remains under‐investigated.

Nocapyrones A−D, γ-Pyrones from aNocardiopsisStrain Isolated from the Marine SpongeHalichondria panicea [PDF]

open access: yes, 2010
Four new γ-pyrones, nocapyrones A−D (1−4), were isolated from an organic extract of the Nocardiopsis strain HB383, which was isolated from the marine sponge Halichondria panicea. These are the first γ-pyrones reported from a Nocardiopsis strain.

Advances in Parahydrogen‐Induced Polarization for Nuclear Magnetic Resonance of Peptides, Proteins, and Biopolymers

open access: yesChemistryEurope, Volume 4, Issue 4, April 2026.
Hyperpolarization by parahydrogen‐induced polarization enhances the sensitivity of nuclear magnetic resonance spectroscopy of amino acids, peptides, mini‐proteins, and biopolymers using nonnatural amino acids with unsaturated side chains up to three orders of magnitude.
