For rats and other rodents, plastics are a popular menu item. Techmer Polymer Modifiers (www.techmerpm.com) has come up with a polymer additive that keeps these pests from nibbling on important plastics. The company's PM 12211E63 Repellent imbues polyolefins and other thermoplastics with a taste that rodents find repulsive. At the same time, the modifier is non-toxic to pets—as well as the rodents themselves. PM 12211E63 has seen use in wire and cable insulation, fiber-optic cables, plastic pipe, garbage containers, agricultural films, and outdoor furniture.
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?
