Nanosafety: Looking at the toxicology of nanomaterials
Nanomaterials are small particles that can be found everywhere, including in the air we breathe. Nanosafety is an emerging area of research dealing with the effect of nanomaterials on health and environment. Dr Ernesto Alfaro-Moreno of the International Iberian Nanotechnology Laboratory in Braga, Portugal, has been involved in continued research on the toxicology of nanomaterials. For his latest study, he […]

How electrons and phonons promote heat transfer in material systems
Miniaturisation is one of the key features of current and future technologies for information processing and control. However, the ability to reduce the size of an electronic component is limited by a decrease in electrical conductivity and an increase in thermal energy dissipation as the device approaches the nano-scale regime. By studying the electronic and vibrational characteristics of high-purity iridium […]

Research Outreach – Issue 131: Vaccines, nanotech, and new teacher troubles
Research Outreach Issue 131 covers the spectrum of scientific research from long-range submarine sensors to using nanotechnology in nuclear fusion, as well as social issues such as building inner strength, and how to support new teachers when teaching ‘out-of-field’. We cover a number of positive new insights in the field of medicine, including a valuable approach to childhood vaccines that […]

NAPLIFE: Advancing nuclear fusion with nanotechnology
Nuclear fusion has long been discussed for its potential as an abundant source of energy. Yet owing to the immense technological challenges involved, the global rollout of the technology still seems a long way off. Dr Tamás Biró and colleagues at the Nano-Plasmonic Laser Inertial Fusion Experiment (NAPLIFE) project, Wigner Research Centre for Physics, Hungary, believe a solution could be […]

Nanotechnology and metal-organic frameworks for carbon capture
Greenhouse gases pose a major environmental threat that needs to be tackled. Nanotechnology offers great potential, with novel nanomaterials such as metal-organic frameworks (MOFs) being strong candidates for the adsorption of greenhouse gases. Dr Ocean Cheung, assistant professor at Uppsala University in Sweden, looked into a MOF sub-category, zeolite imidazolate frameworks (ZIFs), and examined how mixing raw materials for ZIF […]

Maths and honeycombs: Searching for the materials of the future
The nanotechnology revolution is fuelled by the versatility of nanomaterials. Changing a nanomaterial’s composition and structure alters its properties, rendering nanomaterials tailor-made for specific applications. Mathematical modelling guides researchers towards predicting desired behaviour prior to experimentation. Titus Masese of the National Institute of Advanced Industrial Science and Technology (AIST) and Godwill Kanyolo of the University of Electro-Communications (UEC), in Japan, […]
