#ENERGY: "Quantum Dots Enable Windows to Harvest Solar Energy"

The windows of the future could double as solar energy concentrators according to researchers at Los Alamos Natl. Lab which recently demonstrated a prototype: R. Colin Johnson @NextGenLog


Transparent quantum-dot-impregnated window panes luminescence under ultraviolet illumination.

Solar energy is collected by cadmium-selenium (CdSe) quantum dots which pass the energy to a cadmium-sulfur (CdS) inner cores which emits the light at a different wavelength thus concentrating the solar energy from the whole windows surface on the phovoltaic cells around the window's edge.

#CHIPS: "Archer Supercomputer Advancing State-of-the-Art"

Cray scored a major design win with its massively parallel XC30 supercomputer is the fastest in the U.K. for complex simulations--from cosmology to climate modeling to aircraft design--using Intel E5 processor chips and Aries interconnection fabric chips--R. Colin Johnson @NextGenLog


The University of Edinburgh recently installed its Archer supercomputer, which ranks as the fastest supercomputer in England.


Cray XC30 series chassis are based on blades with processor daughter cards (PDCs) and a peripheral component interconnect express (PCIe) Gen3 host interface.

#CHIPS: ISPD-14 "Looks Beyond FinFETs to Secure ICs"

The future of chip design is foretold at the International Symposium of Physical Design. See into the future of ICs in this report on ISPD14. Revealed are the process technologies that will obsolete FinFETs, Understand how to purge counterfeit chips and secure the supply chain, then explore the bright future of cyber-physical systems--R. Colin Johnson @NextGenLog

Look beyond FinFETs to the process technologies that will replace them.

Mentor Graphics shows how to secure the supply chain even though a major part of it is untrusted.

Ninety percent of all future innovations for cars will be on their electronics systems.

#STANDARDS: "NIST Sets New World Record in Accuracy of Atomic Clocks"

As if losing or gaining a second every 100 million years wasn't accurate enough, NIST has not upped the ante to 300 million years and has sights on 3 Billion year atomic clocks! R. Colin Johnson
NISTs new atomic clock is three times as accurate as the previous model that has been the universal standard since 1999.

#MEMS: Tiny Mics to Pass $1B Market Milestone

Micro-electro-mechanical systems (MEMS) microphones combine tiny size with high-definition sound, superior signal-to-noise ratios and wider dynamic range that conventional microphones. They have already become standard faire for mobile devices and in 2014 will pass the $1 billion dollar market milestone, shipping over 2.4 billion units worldwide.
