2013-2014 Dalton Lecturer announced

Wendy Mak, Development Editor — Fri, 17 May 2013 12:45:48 +0000

We would like to congratulate Trevor Hayton, who has been awarded the 2013-2014 Dalton Lectureship, in recognition of his work on actinides, especially his ground-breaking work on f-element chemistry.

This lectureship, sponsored by Dalton Transactions, aims to enhance communication between the best researchers, and is awarded yearly to an outstanding young investigator in the general field of inorganic chemistry.

Trevor will be presenting his lecture at University of California, Berkeley in early 2014, where he will also be spending time with the faculty, postdocs and students.

Trevor Hayton grew up in Surrey, British Columbia. In 1998, he received his B.Sc. in Chemistry from the University of British Columbia, whereupon he began his Ph.D. research, also at UBC, under the direction of Peter Legzdins. After graduating in 2003, he began a postdoctoral fellowship at Los Alamos National Laboratory, working under the direction of James M. Boncella. In 2006 he started a faculty position at University of California, Santa Barbara, where he is currently an Associate Professor.

Updating the textbook on intermolecular interactions

Kate Bandoo, Publishing Assistant — Fri, 10 May 2013 15:55:26 +0000

A researcher in Spain has analysed over five million intermolecular distances to propose a consistent set of van der Waals radii for the most naturally occurring elements.

Santiago Alvarez at the University of Barcelona was about to set his students an assignment analysing intermolecular distances involving lanthanides when he came across a problem. ‘I realised that such an exercise would not work because the Cambridge Structural Database arbitrarily assigned van der Waals radii of 2.0 Å to all elements not included in the short list established by [Arnold] Bondi. It seemed to me that a larger set of consistent Van der Waals radii was needed.’

Color switching in lanthanoid based hybrid materials

Leah Morris, Web Writer — Fri, 12 Apr 2013 13:05:59 +0000

Research interest in hydrid inorganic–organic materials is being driven by their application light sources and optical displays. Lanthaniod elements are attractive as light emitters because of the purity of colours that can be produced and also by combining different lanthanoid elements, they can emit white light. However in lanthanoid elements, f–f transitions need to be activated by a bound ligand.

Mark I. Ogden, Massimiliano Massi and their research teams have found a way of solving the issue of phase segragation in lanthanoid based metallo polymers. When phase separation occurs, the metal complex separates from the organic portion which can affect the emission properties. To overcome this, they copolymerized methyl methacrycalate with a calixarene (basket shaped cyclic oligomer) and then introduced a lanthanoid ion to produce luminescent hybrid materials.

The materials can be changed by loading different combinations of lanthanoid ions which produces different colour emissions – as well as emitting white light.

New Grants Available For RSC Members!

Wendy Mak, Development Editor — Thu, 04 Apr 2013 15:16:35 +0000

The RSC’s Divisions are keen to support their members with their careers and their scientific activities. To this end, we have launched two new grants which allow our members to apply for funding from their Divisions for various purposes.

If you are organising an activity, such as a small “no frills” meeting or a young researcher meeting, and you need funds, the Small Grants for Scientific Activities may be able to help, with grants of up to £2000. Our Divisions have already supported a number of people with their activities, such as Prof. Michael Glazer’s exhibition, entitled “The Two Braggs”, celebrating the centenary of the seminal work on X-ray diffraction by the eponymous father and son team.

In addition, the Small Grants are also available to support early career researchers (more than 5 years post PhD) with travel to conferences they are participating in. For full details, please visit the website at: http://rsc.li/small-grants.

We all know how important it is for young PhD students and post-doctoral researchers to participate in conferences and workshops. So, we’re very pleased to announce our new Travel Grants for PhD Students and Post-doctoral Researchers (within 5 years of completion of PhD). You can apply to your Division for up to £800 for travel to any conference or workshop anywhere in the world that will benefit you or your career. More information can be found at http://rsc.li/ecr-travel.

Both grants are available now. Application is easy; in each case, we ask that you read the terms & conditions and fill out a simple application form.

The spirit of these grants is to provide quick, flexible and transparent sources of funding for our members. You should typically receive a response from your Division within two or three months for the Small Grants and Travel Grants, respectively.

We look forward to receiving your applications.
