Solar cells http://cnx.org/contents/dd0537a2-fb5d-439d-8feb-bf2e50656dae@1 Semiconductor solar cells In physics lessons we tend to just look at semiconductor solar cells. http://en.wikipedia.org/wiki/Solar_cell A solar cell (also called a photovoltaic cell) is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. It is a form of photoelectric cell, defined as a device […]Read more "Begbroke Nano Teachers’ Day"
Making gold and silver nanoparticles I was truly amazed when we were shown the range of colours that silver nanoparticles can produce depending on their size. http://pubs.rsc.org/en/content/articlelanding/2010/jm/c0jm01990a/unauth#divAbstract We were shown pictures of the different colours. I found the above image from the above web link. Each colour is caused by different size silver nanoparticles suspended […]Read more "Begbroke Nano Teachers’ Day"
These activities aimed at finding ways of experiencing the nano world and gaining confidence in using numbers to explain what we can’t see. We have nanodetectors built into our bodies. Our noses are particularly good. We can smell something such as dilute perfume without actually seeing it. To prove this we were given some scented […]Read more "Begbroke Nano Teachers’ Day"
Carbon and making a model Buckyball Introduction Studying material science allows new products to be made with greater efficiency and lower costs. The choice of material for a new product depends on the function of the new product and how its properties will enhance the product. A famous example is reinforced concrete. Concrete itself is […]Read more "Begbroke Nano Teachers’ Day"
An introduction to nanoscience and nanotechnology What is a nanoparticle? A nanoparticle is a particle between 1 and 100 nanometres in size. In nanotechnology, a particle is defined as a small object that behaves as a whole unit with respect to its transport and properties. http://en.wikipedia.org/wiki/Nanoparticle Nanoparticles have been around a long time having first […]Read more "Begbroke Nano Teachers’ Day"
Begbroke Science Park The day’s activities took place at Begbroke Science Park and they were brilliantly coordinated by Dr Vanessa Cheel and Dr Christiane Norenberg. If you are an interested teacher they are running the course again in 2015: 5 March 2015 & 15 July 2015 I can thoroughly recommend this course whatever your specialism […]Read more "Begbroke Nano Teachers’ Day"
