Israeli professors Shlomo Magdassi and Daniel Mandler are members of a research team that invented a window coating material that can be used without blocking the view Block the heat of the sun.

Magdaxi, an expert in materials science and nanotechnology at the Hebrew University of Jerusalem, said: "The research results are expected to create unique windows that will save energy."

According to "Ceramics International", the electrochromic window project was led by Professor Alfred Tok of Nanyang Technological University (NTU) in Singapore in collaboration with researchers from the Hebrew University.

NTU and the Hebrew University have a joint research project. Magdassi and Mandler have been collaborating with NTU to develop new nanomaterials since 2010 and are currently on vacation there.

The coating contains nano-scale quantities of advanced materials, such as titanium dioxide and tungsten trioxide, which can block up to 70% of the infrared radiation from the sun while allowing up to 90% of the sunlight to enter.

This thermal insulation is electrically activated; the user can turn it on and off as needed. Using it in hot weather can significantly save air-conditioning costs.

Scientists said that compared with existing types of electrochromic windows, this cheap and durable coating material is about 30% more efficient in regulating heat. The electrochromic windows are colored to reduce light entry but not block infrared.

The project was funded by the CREATE program of the National Research Foundation of Singapore. Further testing of the material will be conducted at iGlass Asia Pacific, with an eye on incorporating smart windows into its sustainable building projects.
