Storing solar energy as carbon monoxide A team at Indiana University engineered a molecule that collects and stores solar energy without solar panels. The molecule uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide more efficiently than any other method of carbon reduction. Burning fuel such as carbon monoxide produces carbon dioxide and releases e... » read more

Addressing Read-Disturbance Issue In STT-RAM By Data Compression And Selective Duplication


In deep sub-micron region, STT-RAM (spin transfer torque RAM) shows read-disturbance error (RDE) which presents acrucial reliability challenge. We present SHIELD, a technique to mitigate RDE in STT-RAM LLCs (last level caches). SHIELD uses datacompression to reduce cache-write traffic and restore requirement. Also, SHIELD keeps two copies of data blocks compressed to lessthan half the block si... » read more

Revealing the purity of graphene Graphene may be tough, but those who handle it had better be tender, according to researchers from Rice University and Osaka University who have come up with a simple way to spot contaminants given that the environment surrounding the atom-thick carbon material can influence its electronic performance. It is so easy to accidentally introduce impurities into ... » read more
