The University of Bath is a campus university located in Bath, United Kingdom. It received its Royal Charter in 1966. According to 2013 National Student Survey the University of Bath was ranked 1st for student satisfaction out of more than 150 UK higher education institutions. In The Times and The Sunday Times Good University Guide 2014 the University was awarded the title of "Best Campus University in Britain". Bath was awarded the title of ‘University of the Year 2011/12’. In the 2008 Research Assessment Exercise two thirds of Bath's individual subject submissions are ranked in the top ten nationally, including over a third in the top five.The university is a member of the Association of Commonwealth Universities, the Association of MBAs, the European Quality Improvement System, the European University Association, Universities UK and GW4, a grouping which brings together the South West and Wales’ four leading, research-intensive universities . Until 30 October 2012, it was also a member of the 1994 Group. Wikipedia.

Energy storage technologies are critical in addressing the global challenge of clean sustainable energy. Major advances in rechargeable batteries for portable electronics, electric vehicles and large-scale grid storage will depend on the discovery and exploitation of new high performance materials, which requires a greater fundamental understanding of their properties on the atomic and nanoscopic scales. This review describes some of the exciting progress being made in this area through use of computer simulation techniques, focusing primarily on positive electrode (cathode) materials for lithium-ion batteries, but also including a timely overview of the growing area of new cathode materials for sodium-ion batteries. In general, two main types of technique have been employed, namely electronic structure methods based on density functional theory, and atomistic potentials-based methods. A major theme of much computational work has been the significant synergy with experimental studies. The scope of contemporary work is highlighted by studies of a broad range of topical materials encompassing layered, spinel and polyanionic framework compounds such as LiCoO2, LiMn2O4 and LiFePO4 respectively. Fundamental features important to cathode performance are examined, including voltage trends, ion diffusion paths and dimensionalities, intrinsic defect chemistry, and surface properties of nanostructures. © 2014 The Royal Society of Chemistry.

Shigella sonnei is an important cause of bacterial dysentery in the developed world and has also recently emerged in transitional countries. Phylogenetic analysis based on whole-genome sequencing of a global sample has detailed the recent evolutionary history of this pathogen and shed light on the genetic changes associated with this epidemiological shift. © 2012 Nature America, Inc.

The first synthesis of a cyclic oligophenylene possessing a radial π system was reported in 2008. In the short period that has elapsed since, there has been an ever-increasing level of interest in molecules of this type, as evidenced by the volume of publications in this area. This interest has been driven by the highly unusual properties of these molecules in comparison to their linear oligoarene analogues, as well as the diverse array of potential applications for them. Notably, CPPs and related structures were proposed as viable templates for the bottom-up synthesis of single-walled carbon nanotubes (SWCNTs), a proposition which has recently been realised. This review gives a comprehensive and strictly chronological (by date of first online publication) treatment of literature reports from the inception of the field, with emphasis on both synthesis and properties of CPPs and related nanohoops. (The scope of this review is restricted to molecules possessing a radial π system consisting entirely of subunits which are aromatic in isolation, e.g. CPPs, but not cycloparaphenyleneacetylenes or cyclopolyacetylenes). © 2015 The Royal Society of Chemistry.

This paper examines the domestic political economy of so-called 'land-grabbing' in Ethiopia, assessing the motivations of the Ethiopian government, which has strongly promoted foreign agricultural investment. The paper draws on a unique set of federal and regional databases detailing foreign and domestic investments in Ethiopia to analyse the likely role investment will play in the Ethiopian economy and the areas which have been targeted for investment. The analysis identifies increased foreign exchange earnings as the main likely contribution of investment but in doing so highlights concerns for food security in Ethiopia, as the goal of national self-sufficiency has given way to a risky trade-based food security strategy. The paper also argues that the federal government's attempts to direct investment to sparsely-populated lowlands have important implications for the ethnic self-determination that is a key tenet of Ethiopia's federal system. © 2012 Copyright Taylor and Francis Group, LLC.

Twenty years after O'Regan and Grätzel's seminal Nature paper entitled "A Low-Cost, High-Efficiency Solar-Cell Based on Dye-Sensitized Colloidal TiO2 Films", dye-sensitized solar cells (DSCs) and analogous devices have become a major topic of research, with over 1000 papers published in 2010. Although much more is now known about the physical and chemical processes taking place during operation of the DSC, the exponential increase in research effort during this period has not been matched by large increases in efficiency. This raises questions regarding the nature of the barriers that are holding back progress and whether current research is adequately addressing the key issues that are currently limiting device performance. This Perspective attempts to identify some of the factors that determine DSC performance and, as part of a selective survey of recent research highlights, presents a personal view of new approaches and research strategies that could offer ways to overcome the current efficiency stalemate. © 2011 American Chemical Society.
