Computational chemistry proposes T-carbon

Replacing carbon atoms in diamond with pyramids of carbon could produce a new material that is both lightweight and hard. Diamond may have a softer side: T-carbon. This fluffy form of diamond, simulated in a Chinese supercomputer, could be used for a variety of applications — if someone can make the stuff and prove its …

Shift to 450 mm wafers may wait two nodes for the 10 nm node in 2015-2017 according to Intel researcher

The 10-nm process node appears to be the ideal point for the adoption of manufacturing on 450-mm diameter wafers, according Leonard Hobbs, head of research for Intel Ireland. Speaking at the Industry Strategy Symposium here (ISS Europe) he also indicated that the transition could not come sooner and could be pushed later, depending on the …

Progress to a vaccine against Alzheimer’s and stroke

Researchers led by Dr. Dan Frenkel of Tel Aviv University’s Department of Neurobiology at the George S. Wise Faculty of Life Sciences are working on a nasally-delivered 2-in-1 vaccine that promises to protect against both Alzheimer’s and stroke. The new vaccine repairs vascular damage in the brain by rounding up “troops” from the body’s own …

Thin Coating of nanowires will boost thermoelectric effect

Significant Reduction of Thermal Conductivity in Si/Ge Core−Shell Nanowires We report on the effect of germanium (Ge) coatings on the thermal transport properties of silicon (Si) nanowires using nonequilibrium molecular dynamics simulations. Our results show that a simple deposition of a Ge shell of only 1 to 2 unit cells in thickness on a single …

Infinera achieves One Terabit per Second Data Rate on a Single Integrated Photonic Chip

A single PIC can integrate upwards of fifty optical components that would otherwise each require a separate package. Infinera achieved a record one trillion bits per second (1 Terabit/s) speed on a single integrated indium phosphide chip. Infinera’s latest photonic integrated circuits (PIC) is at the heart of a new 10-channel receiver, each channel operating …

China Godson Chip Roadmap and 15 other technology projects

The Godson-3A chip was implemented in a 65 nanometer process and ran at 1 GHz to deliver 16 gigaflops of floating point oomph. The chip has 425 million transistors, an area of 174.5 square millimeters, and burned only 10 watts under load. The chip included two 16-bit HyperTransport ports (licensed from Advanced Micro Devices), 4 …
