Phosphorus‐Structured Gel Electrolytes Enable Dual Protection for Thermal Runaway‐Resistant Lithium Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The PD‐VI GPE synthesized via in situ γ‐ray polymerization facilitates formation of a dense F/P‐rich SEI layer, enabling stable Li deposition while suppressing interfacial side reactions. The phosphorus‐containing framework enhances separator thermal stability and effectively mitigates O2 release from cathodes, demonstrating improved safety under the ...

Development and Biological Evaluation of the First Highly Potent and Specific Benzamide-Based Radiotracer [18F]BA3 for Imaging of Histone Deacetylases 1 and 2 in Brain

open access: yesPharmaceuticals, 2022
The degree of acetylation of lysine residues on histones influences the accessibility of DNA and, furthermore, the gene expression. Histone deacetylases (HDACs) are overexpressed in various tumour diseases, resulting in the interest in HDAC inhibitors ...

A2A Adenosine Receptor Agonists With Last‐Step Enzymatic 18F‐Labelling Potential (Fluorinase) for Positron Emission Tomography (PET)

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This study exploits the comparable binding tolerances between the fluorinase enzyme and the A2A adenosine receptor towards the development of novel C‐2 functionalised 5′‐fluorodeoxy‐adenosine (FDA)‐based agonists with enzymatic 18F‐labelling capability for positron emission tomography (PET).

Recent Developments in Carbon-11 Chemistry and Applications for First-In-Human PET Studies

open access: yesMolecules, 2023
Positron emission tomography (PET) is a molecular imaging technique that makes use of radiolabelled molecules for in vivo evaluation. Carbon-11 is a frequently used radionuclide for the labelling of small molecule PET tracers and can be incorporated into

Rapid, efficient, and economical synthesis of PET tracers in a droplet microreactor: application to O-(2-[18F]fluoroethyl)-L-tyrosine ([18F]FET). [PDF]

open access: yes, 2019
BackgroundConventional scale production of small batches of PET tracers (e.g. for preclinical imaging) is an inefficient use of resources. Using O-(2-[18F]fluoroethyl)-L-tyrosine ([18F]FET), we demonstrate that simple microvolume radiosynthesis ...
