The chemsitry Postgraduate Symposium took place on Wednesday 27th of May 2015 at Warwick. Over 200 staff, students and researchers attended.

Congratulations to Faduma Maddar (third left) for winning the poster prize on her PhD work: "Quantitative Dissolution Kinetics of a Bicalutamide Single Microcrystal in Aqueous Solution: An In situ Atomic Force Microscopy (AFM) and Finite Element Modelling (FEM) Study".

The runner-up talk prize was also won by a Alex Parker for his talk on "New Combinatorial Approaches for Investigating the Localized Dissolution of Dental Enamel and Impact of Surface Treatments".

One of the latest group publications " Redox-Dependent Spatially Resolved Electrochemistry at Graphene and Graphite Step Edges" published in ACS Nano earlier this month has been highlighted as one of the top 10 articles in this month's "In Nano" review. Congratulations to all involved!

The work by the team studies the basal surfaces and step edges of graphene and highly oriented pyrolytic graphite (HOPG) using Ru(NH₃)₆ ^3+/2+, a redox probe whose standard potential lies near the intrinsic Fermi level of graphene and graphite. Using scanning electrochemical cell microscopy and other complementary microscopy techniques, including atomic force microscopy and micro-Raman, the group found a strong dependence of the electron transfer kinetics on the number of graphene layers, with rates increasing with layer number. In graphene and HOPG that were analysed at similar time points after cleavage, there were distinct differences in the electrochemical activity between basal planes and step edges. These differences were accentuated over time in HOPG. The authors suggest that these findings could lead to better understanding of both materials, which could eventually advance their use in a variety of applications.

 Members of the Warwick Electrochemistry and Interfaces group completed the Spring 10K Wolf Run together. The wolf run is a 10 k run, through rough terrain and obstacles designed to encourage teamwork and test endurance. Congratulations everyone!

Congratulations to Zoe Ayres for winning a poster prize in the #RSCAnalyticalPoster competition. The competition was based on twitter, getting global interest, with the aim of creating a poster that succinctly summarised an application of method in analytical science. The competition attracted significant interest with > 1k tweets to an audience of >300 k. Zoe's poster was based on Electrochemical x-ray fluorescence.

Congratulations to Warwick's Sarah-Jane Richards (right) from Dr Matt Gibson's group who also won a prize.

Congratulations to Emma Ravenhill who received the best poster prize a the WE-heraeus-Seminar, Electrochemical Surface Science on the 18th-22nd of January in Germany. The poster was on the "Use of chemical force microscopy to understand nanoparticle-substrate interations in electrochemical collisions. "
