#SUPERCOMPUTERS: "Electronic Brain Promised by 2023"

The European Union is throwing $1.3 billion over 10-years at creating an electronic brain--they already have an Atlas of brain subsystems begun and 100 universities and corporations on-board building them: R. Colin Johnson @NextGenLog

#MATERIALS: "IBM Grows Wafer Scale Grahene"

IBM has not only perfected a method of growing wafer scale graphene as a potential material for the post-silicon era, but has found a way to use it today to dramatically cut the cost of GaN LEDs.


A four-inch wafer of graphene successfully transferred to a silicon wafer.

#CHIPS: "Fairchild Reinvents Itself"

Fairchild aims to pioneer the 21st century by putting together smart modules that solve problems better for energy efficiency, mobility and the cloud.

As an example of Fairchild's modernization, it is now fabricating complete compact, high-efficiency, cost-effective modules aimed at driving up quality while driving down costs to its customers.

#ENERGY: "IBM/Airlight Beat Chinese PV with Higher Tech"

IBM and its collaborator AirLight believe they can beat the price of even the cheapest Chinese photovoltaic panels with a higher-tech disk based system that produces 12 kW of electricity and 20 kW of heat that can be used for HVC or desalinating water or both: R. Colin Johnson @ NextGenLog



This solar dish produced up to 20 KW thanks to a collaboration between Airlight Energy, which has perfected low-cost solar concentration to 2,000X, and IBM, which has perfected water-cooling chips down to 105 degrees that would otherwise be driven up to 1,500 degrees.

#MEMS: "Piezoelectric MEMS mics Seem Destined to Take Over"

Piezoelectric MEMS microphones have already chalked up 70 dB signal-to-noise rations (SNRs) and are on their way to 80 dB, which is virtually unattainable by the conventional capacitive MEMS mics that everybody else makes: R. Colin Johnson @ NextGenLog






Instead of a traditional round diaphragm like capacitive microphones use (right) piezoelectric microphones use a square block of piezoelectric material (aluminum nitride, green) divided into four triangles (along the X from corner to corner) which stretch and contract--but never touch--thus creating an ultra low-noise signal picked up by the metal (yellow and gold) electrodes.

#CHIPS: 10 Best Bets for Next Gen Memory"

Here are my best guess at the next-generation of memory storage technologies except for MRAM, 3D NAND, RRAM and Spin-Transfer Torque RAM (STT-RAM), which were left out for various reasons: R. Colin Johnson
