Fabricating polymer tandem solar cells with a graphene-based conductive glue

Apart from making graphene, graphene oxide itself itself is a fascinating material that has many intriguing properties. Researchers have noe developed a graphene-based conductive glue that can function as a metal-free solder for creating mechanical and electrical connections in organic optoelectronic devices. As a proof-of-concept, they fabricated polymer tandem solar cells - multi-junction photovoltaic devices, in which two sub-cells are stacked to achieve higher overall solar absorption - by a direct 'gluing' process. The water-based sticky interconnect and the associated adhesive lamination process could transform the serial layer-by-layer fabrication of tandem devices into a parallel mode, in which the subcells can be independently fabricated and adjusted to balance their photocurrents for achieving high efficiency.

Domtar and FPInnovations Joint Venture to be Named CelluForce

CelluForce will manufacture nanocrystalline cellulose, a recyclable and renewable nanomaterial, that will be commercialized throughout the world. The new company's identity was developed to reflect both the origin of the nanomaterial, extracted from tree cellulose, and one of the multiple properties of the product to be sold by the new company.

Early Results of Development Program in Nano-Formulated NSAIDs Show Potential for Faster Pain Relief at Lower Doses

A novel, lower-dose formulation of indomethacin, a widely used pain reliever, is absorbed faster by the body than a standard formulation and maintains comparable maximum concentrations in the blood despite being administered at a lower dose, according to a study to be reported here tomorrow at the annual meeting of the American Headache Society.

Oxford Instruments and Green Imaging Technologies announce NMR partnership

Oxford Instruments Magnetic Resonance (OIMR) and Green Imaging Technologies, Inc. (GIT) have announced an agreement to establish a strategic partnership to bring complete cutting edge Nuclear Magnetic Resonance (NMR) solutions to the core analysis community. The partnership will open opportunities for NMR core analysis to be used by technicians with no specialist NMR knowledge or training and make special core analysis routine.
