Manufacturing Bits: Nov. 8


Self-healing magnetic ink The University of California at San Diego has developed a self-healing magnetic ink. The ink can be used to print inexpensive electrochemical devices, such as batteries, sensors, textile-based electrical circuits and other products. A key to the technology is the self-healing concept. This means a device could autonomously repair itself in the field. Over the ye... » read more

Still Searching For Rare Earths


There is both good and bad news for buyers of rare earths. The good news: It’s a buyers’ market. Prices for rare earths remain depressed amid a glut in the marketplace. The bad news: The supplier base is shaky. China still accounts for 85% of the world’s total production of rare earths, but most Chinese suppliers are operating at a loss. And two of the main non-Chinese suppliers, M... » read more

Manufacturing Bits: June 9


Making rare earths Rare earths are chemical elements found in the Earth’s crust. They are used in cars, consumer electronics, computers, communications, clean energy and defense systems. The big market for rare earths is magnets. In semiconductor production, rare earths are used in high-k dielectrics, CMP slurries and other applications. China has a monopoly in rare earths, accounting for... » read more

Searching For Rare Earths Again


Rare earths are back in the spotlight again. Rare earths are chemical elements found in the Earth’s crust. They are used in cars, consumer electronics, computers, communications, clean energy and defense systems. The big market for rare earths is magnets. In semiconductor production, rare earths are used in high-k dielectrics, CMP slurries and other applications. Last year, the World Tr... » read more

Power/Performance Bits: Nov. 26


Many people are predicting that power will be the issue that brings Moore’s Law to an end. Power creates heat and that heat can be destructive to chips, so there are two paths forward – the first is to reduce heat and the second is to get it off chip. It seems as if magnets may be the common key to both approaches. Magnetic Transistors New work by researchers at UC Berkeley soon could t... » read more
