Nicola is a highly distinguished theorist who has made many seminal contributions to new computational and theoretical tools for calculating the properties of complex solids and their application to the rational design and understanding of new multifunctional materials. She is a fellow of the APS, MRS and AAAS and has won numerous awards for her research and educational activities.

She has generously agreed to give a series of Masterclass lectures which will provide a unique opportunity for all LJC students and post-docs to learn about computational methods in complex solids and multiferroics. The lectures will be accessible to computational and theoretical physicists, chemists and materials scientists. All members of the LJC are welcome.

NPCM website.png 29th March 2016: New Nano-Phase Change Materials Website Launched.

The collaboration between this Group and the Warwick NPCM group has a new website. The global demand for smaller and more energy efficient devices has been sustained by a steady decrease in the scale on which silicon microelectronics can be manufactured. To continue this trend beyond the mid 2020s devices with dimensions of just 1-2nm will be required, likely using alternatives to silicon.

In this regime, the cross section of a wire might be no more than 2x2 or 3x3 atoms across, where the relevant materials physics is dominated by surface and confinement effects leading to dramatically different structural and electronic properties to the corresponding bulk material. Such wires can be formed by crystallisation of a molten salt within carbon nanotubes (CNTs) of "Buckytubes", leading to the smallest cross section nano crystals possible, sometimes referred to as Feynman crystals.

Research into the fundamental materials physics of these CNT-encapsulated structures is still in its infancy, with UK experimentalists leading the way.

LiGe.png January 2015: Elucidation of the Local and Long-Range Structural Changes that Occur in Germanium Anodes in Lithium-Ion Batteries - New Paper

Metallic germanium is a promising anode material in secondary lithium-ion batteries (LIBs) due to its high theoretical capacity (1623 mAh/g) and low operating voltage, coupled with the high lithium-ion diffusivity and electronic conductivity of lithiated Ge. In contrast to previous work, which postulated the formation of Li9Ge4 upon initial lithiation, we show that crystalline Ge first reacts to form a mixture of amorphous and crystalline Li7Ge3 (space group P3212). Which we predicted to be stable in our recent theoretical study Phys. Rev. B 90 054111 (2014).

Elucidation of the Local and Long-Range Structural Changes that Occur in Germanium Anodes in Lithium-Ion Batteries published in Chem. Mater. 23 1031 (2015).

LiS.png November 2014: Ab Initio Structure Search and in Situ 7Li NMR Studies of Discharge Products in the Li-S Battery System - New Paper

The high theoretical gravimetric capacity of the Li-S battery system makes it an attractive candidate for numerous energy storage applications. In practice, cell performance is plagued by low practical capacity and poor cycling. In an effort to explore the mechanism of the discharge with the goal of better understanding performance, we examine the Li-S phase diagram using computational techniques and complement this with an in situ 7 Li NMR study of the cell during discharge.
