Naked Scientists

Dr Paul Coxon presented Archimedes' Principle to the Naked Scientists as part of a show about important science experiments through the ages. The recording was broadcast as three radio shows and downloadable podcasts on BBC 5 Live, BBC Cambridgeshire and ABC Radio National (Australia) to an audience of over a quarter of a million listeners.

Paper of the Month

A lithium-sulphur battery embodies energy which is several times superior to the conventional Li-ion battery. Rapidy decay of this energy has been a significant obstacle hampering practical applications, the loss of capacity mainly arises from dissolution of lithium polysulphide in the electrolyte followed by diffusion away from the cathode. In order to overcome this problem, we have prepared a composite cathode made of sulphur and a high density carbon nanotube (HD-CNT) forest scaffold that is able to interfacially adsorb and volumetrically confine the polysulphide species and accommodate the expansion of sulphur discharge products effectively.

Advanced Lithium-Sulfur Batteries Enabled by a Bio-Inspired Polysulfide Adsorptive Brush.’ Advanced Functional Materials (2016)

R. Vasant Kumar, Renjie Chen and co-authors present a bio-inspired chemically functional interlayer for rechargeable lithium-sulfur batteries. This interlayer, made from zinc oxide nanowires grown on a conductive scaffold, has a villi-like structure. It lies on top of cathode to trap active materials and keep them electrochemically accessible, resulting in greatly improved cycle and rate performance.

Dual coexisting interconnected grapheme nanostructures for high performance supercapacitor applications

A facile and scalable high-temperature molten salt method was used to synthesize a high-quality hierarchical carbon nanostructure consisting of graphene nanosheets and nanoscrolls with an inter-connected network and high electrical conductivity. During the process, the intercalation of lithium and hydrogen from molten LiCl into graphite led to the formation of a coexisting graphene sheet– scroll nanostructure. An electrode using the fabricated interconnected carbon nanostructure showed a highly reversible specific capacitance of 213 F g1 at 1 A g1 initial specific capacitance (1 A g1(97.9% after 10 000 cycles). Such remarkable electrochemical performance is desirable for supercapacitor/ultracapacitor applications., excellent capacitance retention (84.5% of the) at 50 A g1), and good cyclability. (97.9% after 10 000 cycles). Such remarkable electrochemical performance is desirable for supercapacitor/ultracapacitor applications.
