A quick update of what I have been up to

February 25, 2011

First of all, I’d like to apologise to my readers for the ridiculously long absence. I have been busy – honest. A lot of what I have been doing involved helping to organise things for the British Science Association National Science and Engineering Week – this event that we are running in the Grafton Centre, Cambridge should be very exciting. We have lots of new (to us) experiments on the (loose) theme of communication. Do stop by and see what we are up to if you are in the area.

It being the start of spring, I’ve also been busy in the garden. Sort of science, sort of muddy fun….

And finally, I have written and published several nice stories on various topics (but mainly graphene):

How to spot monolayers – Question: how can you tell if your boron nitride layer is a monolayer or two or three layers overlaid? Answer: with this easy Raman technique developed by graphene kings Andre Geim and Kostya Novoselov’s group.

Gold nanoparticle network growth – metal nanoparticle systems are being used extensively and increasingly in biological, chemical and physical studies, so understanding what makes them tick is really important.

Bionanoelectronics – no Frankenstein –  a neat summary of how bioelectronics is being used today and how it will/could/should revolutionise the world tomorrow.

Graphene tracks for aluminum trains – I thought this was cool. Basically a graphene surface was modified with electronic contacts such that a cluster of Al can be moved along it and even made to turn corners on it. (And an apology for the spelling of aluminium here – Wiley require US spellings so that is what I used – but I particularly dislike this one!)

Speed dating for pharmaceuticals – a computational study that could be really handy for those med chemists trying to find the best way to deliver drugs (or ways to repatent old ones) – it calculates the strength of all hydrogen bonds in the crystal of an active component and a co-crystal partner and comes up with what would make the most likely partners.

Hope you like these, enjoy!

Logic gates take the strain and various surface modifications

September 14, 2010

Some more of my work has appeared on Materials Views….

A story on a paper by ZL Wang and co-workers on smart logic gates that can be operated by simply bending the substrate. This story made it to the MaterialsViews newsletter as headline – it’s a nice piece of work but I would like to think that my write-up also had something to do with this!

A piece on single layers of quantum dots arranged on a surface, and another on stripey patterns on a surface by the use of combined top-down and bottom-up approaches.

To be honest I wrote these so long ago I can’t remember much about them but I think they were pretty good papers. The piezotronic switching logic gate I remember slightly better and this was pretty cool. Enjoy.

Small things on surfaces.

September 3, 2010

A couple more of my pieces are now live on the MaterialsViews website, Nano Channel. Here you can read about work to exploit all 3 dimensions of a patterned photoresist from the ubiquitous Whitesides group, and also a method for focussed nanopatterning. Both, basically, discuss how to make small things on surfaces.
