of 10,000 insertion/removal cycles for SD Memory Cards and 12,000 cycles for memory sticks.
With the RK12L115, ALPS ELECTRIC EUROPE GmbH offers a 12mm size carbon rotary potentiome- ter with linear resistance characteristics. The robust ALPS potentiometer with a 25mm flat, insulated pla- stic shaft of 6mm in diameter is available as snap-in type for vertical PCB assembly. It has a compact, low profile design with dimensions of 12.0mm x 11.2mm x 7.5mm (W x D x H).

MRI‘s (NASDAQ: AMRI) board of directors has approved a new share repurchase program of
lopment of hybrid nano graphene platelet-based high-capacity anodes for Lithium-ion (Li-ion) batteries. The team will commercialize its new an- ode technology which has the capability to capture the high charge capacity allowed with silicon over extended charge/discharge life, using a network of highly conductive yet inexpensive nanoscale graphite filaments.
Headquartered in Dayton, Ohio, Angstron Materi- als Inc., a world leader in the production of nano graphene platelets (NGPs) developed its patented graphene material and manufacturing processes as a cost effective alternative to carbon nanotubes. NGPs offer striking material properties including the highest intrinsic strength and the highest thermal conduc- tivity of all existing materials as well as exceptional in-plane electrical conductivity (up to ~ 20,000 S/ cm) and electron mobility that is 100 times faster than silicon.
Angstron and K2 will conduct the project over three phases with initial activity focused on demonstrating the commercial and technical viability of new high- energy anode materials. This will include delivering data on anodes capable of initial specific capacities of 650 mAh/g and achieving ~50 full charge/dischar- ge cycles in small laboratory scale cells (50 to 100 mAh) at the 1C rate with less than 20% capacity fade. Phase II will target development of process technology for cost-effective production of the opti- mized Si-coated NGP/CNF blends.
As the project moves forward, 18650 or larger format cells will be assembled with the anode material, cycled, and examined to evaluate any failure modes under cycling and calendar aging as well as demons-
