Together with BRUAG Fire Protection AG, Empa specialists have developed a new flame retardant for wood and wood-based materials. The colourless additive, which can be easily mixed with coatings and cellulose materials, opens up new applications for wood processing companies. Fire protection requirements are increasing worldwide - especially in public buildings and vehicle construction. This development means that more and more otherwise suitable materials such as wood can no longer be used in many buildings or means of transport and must be substituted by other products. The aim of the CTI funded research project was therefore to develop a flame retardant that increases the fire resistance of such materials without impairing the positive properties of the materials.

Graphene is considered one of the most interesting and versatile materials of our time. The application possibilities inspire both research and industry. But are products containing graphene also safe for humans and the environment? A comprehensive review, developed as part of the European graphene flagship project with the participation of Empa researchers, investigated this question.

The efficiency of a solar cell is one of its most important parameters. It indicates what percentage of the solar energy radiated into the cell is converted into electrical energy. The theoretical limit for silicon solar cells is 29.3 percent due to physical material properties. In the journal Materials Horizons, researchers from Helmholtz-Zentrum Berlin (HZB) and international colleagues describe how this limit can be abolished.
