Welcome to Manish and Conor!

We welcome two University of Manchester physics undergraduate students to the group for a summer project. Manish Patel joins us to spend 6 weeks looking at how to identify the same nanowire twice on a substrate of 100,000 – not an easy challenge when they all look the same! Conor

Publication - Size-Independent Energy Transfer

Our new manuscript has been accepted for publication in ACS Nano. The study, “Size-Independent Energy Transfer in Biomimetic Nanoring Complexes” was conducted with colleagues at the University of Oxford Physics (Herz Group) and Chemistry (Anderson Group). For more details, see the ASAP article at doi:10.1021/acsnano.6b01265.

From supra-molecular chemistry...

Patrick’s talk from the Frontiers of Science talk in Canada is now online – https://www.youtube.com/watch?v=YkxGFyrrwqo.

New Publication - Characterization of a silica-PVA hybrid for high density and stable silver dissolution

Work led by Bryce Dorin, a PhD student associated with the OMS group, has led to a new publication in Materials Chemistry and Physics (Volume 177, page 19). Bryce is seeking to develop new materials and approaches to use femtosecond laser processing techniques to make conductive tracks within insulating material.

Lab Progress - first data

After an extended ~ 3month move period, the micro-PL system is back up and running with our new laser system. Just in time for Arturo to get started on his new project…!

Conference - Royal Society Frontiers

Patrick has presented an invited talk at the Royal Society Frontiers of Science meeting, held in Vancouver, Canada. Speaking in the “How to Mimic Nature” session, Patrick spoke about using supra-molecular chemistry to create super-natural molecules by learning from photosynthesis. The meeting was a joint event hosted by the Royal

Welcome to Arturo!

A warm welcome to Arturo, who joins the group from San Luis Potosi in Mexico on a CONACyT-funded PhD program. Arturo will be focussing on the optical and electronic spectroscopy of semiconductor nanowires, and is supervised by Patrick Parkinson and Prof Phil Dawson in the School of Physics and Astronomy.

Conference - ICONN 2016

Patrick has given a talk at ICONN 2016 (the International Conference on Nanoscience and Nanotechnology), held in Canberra, Australia. The conference had sessions focussing on nanophotonics, nanomaterials, nanocharacterisation, nanoelectronics and commercialisation/safety issues. Patrick spoke on “Statistical Study of Nanowire Disorder”, covering new work as well as Christopher Davies recent

Lab Progress - Laser up and running

The laser engineer has got the laser up and running. Hopefully the OPA’s will be ready by the end of tomorrow. 1.45W at 250kHz, 800nm with 205fs autocorrelation (117fs transform-limited duration); we’re running above specifications with a peak power of ~48MW.

Lab Progress - laser in

The laser is now in place, ready for installation in the new lab space. The overhead tables and wiring are good, and we are just waiting for the laser technicians to arrive to complete the installation.
