The epidemic of chronic non-communicable diseases ( CNCD’s), accounting for 60 % of deaths annually, is well-entrenched in the Caribbean region. Obesity underlies many of the CNCD’s including type 2 diabetes, hypertension, cardiovascular diseases and many forms of cancer. In this paper the evolution and impact of this unfolding story of CNCD’s in a developing Caribbean country will be explored. The emergence of obesity and diabetes among children is of particular concern and the high prevalence of both these conditions in pregnancy has implications for future health, well-being and economic development of the region. Our attempts to address these concerns will be presented and collaborative links with Commonwealth colleagues who share these interests.
The widespread integration of renewable, intermittent energy sources such as wind or solar is dependent upon the development of efficient large-scale energy storage systems for load-levelling the electric grid. Similarly, the acceptance of plug-in hybrid electric - and especially pure electric vehicles - hinges on the availability of intermediate scale, safe, low-cost energy storage batteries to provide driving ranges that greatly exceed the psychological barrier of > 300 miles. Combined, these approaches can mitigate CO2 emissions and urban pollution.
This talk will present a perspective on the development of advanced energy storage systems - including Li-ion batteries - and a synopsis of their basis in chemical and materials science. The challenges, opportunities and perceived limits for future improvements will be presented, including storage materials that go “beyond Li-ion”. These include exciting new technologies based on sulphur and oxygen that could meet the needs for high energy density storage. Also, energy storage systems based on Na-ion, once sidelined owing to their lower energy density, are now winning back interest due to their cost advantages and sustainability that benefit large-scale storage. Significant advances in all of the above made possible through the exploitation of chemistry and nanotechnology will be highlighted.
