University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

Synthesis and Biological Evaluation of Some New Chalcones Containing 2,5-Dimethylfuran Moiety

E-Journal of Chemistry, 2011
A series of new chalcones (3a-g) were prepared by Claisen-Schmidt condensation of 3-acetyl-2,5-dimethylfuran with various substituted aromatic aldehydes in presence of aqueous solution of potassium hydroxide and ethanol at room temperature.

A novel sulfur‐containing photoinitiator based on benzophenone derivatives for rapid photopolymerization

Smart Molecules, EarlyView.
This study develops a series of unimolecular photoinitiators, BP‐S1‐5, by incorporating hydrogen‐donating groups into a benzophenone framework. This method reduces the reliance on co‐initiators, and enables BP‐S1‐5 with efficient photoinitiation and excellent molding capability.
