Photogenerated Oxetanes as a Gateway to Uphill Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
An atom‐economical route to densely functionalized cyclopropanes from furans and photochemically activated aldehydes is enabled by a unique oxetane‐to‐cyclopropane rearrangement. These cyclopropanes can be used to access complex bioactive scaffolds and serve as a platform for asymmetric cyclopropane synthesis.

A gold-coated titanium oxide nanotube array for the oxidation of borohydride ions

Electrochemistry Communications, 2012
Highly ordered titanium dioxide nanotube (≈ 100–200 nm pore diameter) arrays, were formed on a titanium foil by anodising at a cell voltage of 60 V, in two stages. The nanotube arrays were over-coated with nanoparticulate gold using physical vapour deposition (PVD) sputtering resulting in a well dispersed coating.

The Oxidation Mechanisms of Saturated Fatty Acids: Formation of Hydroperoxide Isomers and Production of 2‐Alkanones and Lactones

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saturated fatty acids (SFAs) are generally regarded simply as being resistant to oxidation compared with unsaturated fatty acids. However, it has long been reported that SFAs can undergo oxidation when heated at high temperatures, leading to the formation of unique degradation products such as 2‐alkanones and lactones.

Glycosylated dendrimer nanoamplifiers hijack DNA damage‐immune crosstalk for enhanced dual‐track therapy of orthotopic glioblastoma

BMEMat, EarlyView.
A glycosylated dendrimer nanoamplifier hijacks DNA damage‐immune crosstalk for enhanced radio‐immunotherapy of glioblastoma. The responsive release of demethylcantharidin simultaneously blocks repair‐mediated resistance by inhibiting DNA repair and overcomes adaptive immune resistance.
