NIDA researchers confirm important brain reward pathway

Details of the role of glutamate, the brain’s excitatory chemical, in a drug reward pathway have been identified for the first time.

Silver-free Metallization of Solar Cells by Means of Laser and Screen Printing

The newly developed process combines the LIFT (Laser Induced Forward Transfer) process and screen printing to produce the front contacts of solar cells.
The combination allows the minimization of contact and line resistances even in industrial scale production and is associated with substantially reduced costs of materials. In particular, silver is being replaced with nickel or copper.
In addition to saving costs by not using silver the process optimizes the contact and line resistance which increases the solar cell's efficiency.
The German patent has been granted.

Key Component for the Intergration of Electronic Data Processing and Optical Information Transmission

The use of light for information transfer allows high data transfer rates. Processing of the data is done almost exclusively electronically in integrated, silicium based components. The novel electro-optical component is based on the rapid change of transmission characteristics of an optical wave guide by means of the application of electric potentials, respectively the induction of electrical currents. It offers high electric band and can be operated on low voltages.

NF-κB-activated dendritic cells

This technology here describes an immune-therapeutic approach with dendritic cells (DC) for the treatment of cancer. It overcomes constraints of current DC therapy models like limited IL-12 production, a cytokine which is critical for immunologic memory. Therefore and most importantly, cytotoxic T cells induced by these designer DC combine a memory-like phenotype and a markedly increased secondary expandability with a high lytic capacity. Furthermore, this approach is by far more cost efficient than competing products.
