Enabling Quantitative Benchtop 13C NMR Spectroscopy in Fast Continuous Flow

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Paramagnetic relaxation enhancement (PRE) accelerates polarization buildup in continuous‐flow benchtop 13$$ {}^{13} $$C NMR spectroscopy by the use of an immobilized PRE agent. By combining PRE with PENDANT polarization transfer, weak 13$$ {}^{13} $$C signals are enhanced even at high flow rates, enabling robust quantitative analysis of solvent ...

CEEN: A Control Software for Coupled Electrochemistry, EPR, and NMR for Redox Flow Battery and Electrosynthesis Research

open access: yesMagnetic Resonance in Chemistry, EarlyView.
We present CEEN: a Python‐based control software for coupled electrochemistry, EPR, and NMR for redox flow battery (RFB) and electrosynthesis research. We demonstrate CEEN through practical applications relevant to aqueous organic and inorganic RFB and electrochemical synthesis research. The same setup can be readily used to study any (electrochemical)

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.

Physicochemical Reinforcement Unlocks Sterilization‐Stable Anisotropic Hydrogels for Cell‐Compatible Mock Arteries

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 24, 25 June 2026.
ABSTRACT In vitro arterial models offer ethical and robust alternatives for vascular research but require cytocompatible materials that replicate physiological mechanics. Poly(vinyl alcohol) (PVA) hydrogels produced by directional freezing and salting‐out (PVA DFSO) are anisotropic yet lack stability for cell culture. Herein, methacrylated PVA (PVA‐MA)
