SABRE hyperpolarisation of vitamin B3 as a function of pH [PDF]

open access: yes, 2017
In this work we describe how the signal enhancements obtained through the SABRE process in methanol-d4 solution are significantly affected by pH. Nicotinic acid (vitamin B3, NA) is used as the agent, and changing pH is shown to modify the level of ...

RETRACTED: Learner emotions and performance in hypercasual VR games with adaptive AI difficulty

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Hypercasual virtual reality games (HVRGs) are widely regarded as cost‐effective tools for rapid skill acquisition, yet the mechanisms that optimise their effectiveness and user acceptance remain insufficiently explored. This mixed‐methods empirical study investigates how playful emotions, characterised by engagement, enjoyment and anxiety ...

Development of a fully automated workstation for conducting routine SABRE hyperpolarization

open access: yesScientific Reports
SABRE is emerging as a fast, simple and low-cost hyperpolarization method because of its ability to regenerate enhanced NMR signals. Generally, SABRE hyperpolarization has been performed predominantly manually, leading to variations in reproducibility ...

Facile hyperpolarization chemistry for molecular imaging and metabolic tracking of [1–13C]pyruvate in vivo

open access: yesJournal of Magnetic Resonance Open, 2023
Hyperpolarization chemistry based on reversible exchange of parahydrogen, also known as Signal Amplification By Reversible Exchange (SABRE), is a particularly simple approach to attain high levels of nuclear spin hyperpolarization, which can enhance NMR ...

MRI for Mixing Quality in Microfluidics

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Fluidic mixing in a micromixer: Paramagnetic relaxation enhancement and chemical shift differences were explored to reveal mixing quality at the small dimensions of an optically opaque y‐mixer. ABSTRACT Liquid state processes often involve mixing of process streams.
