The latest directory from the Metal Powder Industries Federation (MPIF) makes powder metallurgy players a bit easier to find. The 2003 PM2 Buyers Guide lists the manufacturing, materials, and product capabilities of 147 suppliers of powder metallurgy components and subassemblies. And the 2003 PM2 Suppliers directory lists 163 companies and organizations that produce the various metal feedstocks, make process equipment, and provide powder metallurgy services. Copies of the directory are available from the MPIF. Visit www.mpif.org.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
