Efficient Rechargeable Li-CO Battery with a Liquid Electrolyte-Soluble CuCl Electrocatalyst.

We demonstrate here a simple liquid electrolyte soluble Cu-compound, viz., cupric chloride (CuCl) as an alternative electrocatalyst for nonaqueous Li-CO batteries. The key point behind the selection of CuCl is that the theoretical potential of Li-CO batteries (≈2.

Silk and its composites for humidity and gas sensing applications.

Silk fibroin (SF) is a natural protein largely used in the textile industry with applications in bio-medicine, catalysis as well as in sensing materials. SF is a fiber material which is bio-compatible, biodegradable, and possesses high tensile strength. The incorporation of nanosized particles into SF allows the development of a variety of composites with tailored properties and functions.

Remarkable uptake of CO2 and CH4 by graphene-Like borocarbonitrides, BxCyNz.

The surface areas and uptake of CO(2) and CH(4) by four graphene samples are measured and compared with activated charcoal. The surface areas are in the range of 5-640 m(2) g(-1), whereas the CO(2) and CH(4) uptake values are in the range of 18-45 wt % (at 195 K, 0.1 MPa) and 0-2.

Binding of DNA nucleobases and nucleosides with graphene.

Interaction of two different samples of graphene with DNA nucleobases and nucleosides is investigated by isothermal titration calorimetry. The relative interaction energies of the nucleobases decrease in the order guanine (G)>adenine (A)>cytosine (C)>thymine (T) in aqueous solutions, although the positions of C and T seem to be interchangeable. The same trend is found with the nucleosides.
