Work by Prof Nik Kaltsoyannis highlighted in JACS and Nature
Recent computational work by Prof Kaltsoyannis (J. Am. Chem.Soc., 2012, 134 (15), 6500–6503), carried out in collaboration with the experimental teams of Profs Aldridge and Mountford from the University of Oxford, and Prof Jones from Monash University, regarding the properties of the first reported stable two-coordinate acyclic silylene, has been highlighted in “Spotlight on Recent JACS Publications” (J. Am. Chem. Soc., 2012, 134 (17), 7195) and in Nature (Nature, 2012, 485, 49–50) More...
Structure and Biological Activity of Glasses and Ceramic
Dr Antonio Tilocca has edited with Alastair Cormack a theme issue of Philosophical Transactions of Royal Society A titled "Structure and Biological Activity of Glasses and Ceramics". The issue illustrates recent developments on topical biomaterials, including silicate and phosphate bioactive glasses, contributed by leading researchers in the field. More...

Bromomaleimide-Linked Bioconjugates Are Cleavable in Mammalian Cells

Bromomaleimides are versatile scaffolds
that allow facile conjugation of thiolated biomolecules. Here we
demonstrate that bromomaleimide-linked GFP–rhodamine FRET pairs
cleave in the cytoplasm of mammalian cells. We believe that
bromomaleimide scaffolds provide a potential core structure for
prodrugs designed to release bioactive cargo following cell
internalisation. More...
Perspective: Quo Vadis, agostic bonding?
The ability of some organometallic compounds to form agostic bonds has been first recognises by M.L.H. Green and M. Brookhard in 1983. In this perspective contribution, a more personal look of how this area has developed over the last decades is reported. More...
Water droplet bouncing—a definition for superhydrophobic surfaces
The ability of water to bounce on a surface provides an indication of many of the surface’s properties. The technique described in this article uses water bouncing to determine the hydrophobicity of a surface, with a relationship established between water contact angle and number of bounces. Which, in-turn, is shown to be dependent on the surfaces microstructure. More...

Our achievements in chemical research have been recognised at the highest levels and we are consistently acknowledged as being one of the top Chemistry Departments in the UK. Our location in Bloomsbury at the heart of London means that the UCL Chemistry Department offers an exciting and vibrant environment in which to study Chemistry. More...
The Use of Combinatorial Aerosol-Assisted Chemical Vapour Deposition for the Formation of Gallium-Indium-Oxide Thin Films
This
paper describes the use of combinatorial aerosol-assisted chemical vapour deposition (cAACVD) to
deposit gallium-doped indium oxide thin films. The oxide films, GaxIn2-xO3, were deposited
within composition graduated films from the aerosol-assisted CVD of GaMe3, InMe3 and
HOCH2CH2OMe. Amorphous Ga2O3 was
deposited closest to the inlet from the bubbler containing GaMe3/HOCH2CH2OMe
whereas crystalline In2O3 was grown on the substrate
closest to the inlet from the bubbler containing InMe3/HOCH2CH2OMe.
A range of gallium-indium-oxide compositions, GaxIn2-xO3,
were deposited on the substrate in the region between the two inlets. This allowed
for a systematic investigation on the effect of doping on gallium and indium
oxide and a direct relationship between composition and conductivity of the
films was observed. This new technique combines
the advantages of AACVD (volatility/thermal stability restrictions are removed)
with those of cAPCVD/cLPCVD (rapid deposition/analysis of a compositional
gradient). By utilizing a liquid-gas aerosol, as is employed in combinatorial
AACVD, the restrictions of volatility and thermal stability are lifted and so
new precursors and materials can be investigated. More...
