    To be able to rework aircraft components made of carbon-fiber reinforced plastics (CFRP) more efficiently in the future, the Laser Zentrum Hannover e.V. (LZH) has started the joint research project ReWork together with the INVENT GmbH, OWITA GmbH und Precitec Optronik GmbH. The aim of the project is to develop a reliable process for thin-walled and complex CFRP components. Today, many aircraft components are made of the lightweight material CFRP. Advantages of this material are the low weight and the high stability. The processing of this material, however, is still difficult. Therefore, in order to eliminate production- and operation-related defects in a faster and more cost-efficient way, the aircraft industry requires a reliable solution.

    At the international iGEM academic competition in the field of synthetic biology, the joint team of students from the Technical University of Munich (TUM) and the Ludwig Maximilian University of Munich (LMU) won the first rank (Grand Prize) in the “Overgraduate” category. The team from Munich developed an innovative process which allows intact tissue to be built with the use of a 3D printer.

    Graphenea is launching “Easy Transfer”: the easiest way to transfer monolayer graphene onto your substrate. We applied our extensive experience in growing and transferring high quality graphene films to let you experiment with any novel substrate by using Graphenea’s Easy Transfer.

  • Novel light sources made of 2D materials

    Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape. So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been surrounded by a virtual hype in the past ten years. This is because they show great promise to revolutionise many areas of physics.

  • Silicon solar cell of ISFH yields 25% efficiency with passivating POLO contacts

    The Lower Saxon‘ Institute for Solar Energy Research Hamelin (ISFH) achieved a solar cell efficiency of 25 % in collaboration with the Institute of Electronic Materials and Devices (MBE) of the Leibniz Universität Hannover. This high efficiency was accomplished with passivating "poly-Si on oxide" contacts (POLO) for both polarities, which avoid the otherwise high recombination beneath the metal contacts. The Lower Saxon‘ Institute for Solar Energy Research Hamelin (ISFH), an affiliated institute of the “Leibniz Universität Hannover” in collaboration with the Institute of Electronic Materials and Devices (MBE) of the “Leibniz Universität Hannover” achieved a solar cell efficiency of 25 %. This result was confirmed by DAkkS-accredited independent calibration laboratory ISFH CalTeC and presented at the Asian conference PVSEC-26 in Singapore.
