Waterloo scientists help create 3D map of the universe

Posted by in category: cosmology

Scientists at the University of Waterloo played a big role in a 20-year global project to make a 3D map of the universe, which will help improve knowledge about the expansion of the universe.

Welcome to The National, the flagship nightly newscast of CBC News.

New Spin Record Set: 1 Million rpm

Posted by in categories: electronics, energy

Circa 2008


Industrial motors can spin at a head-spinning 250,000 revolutions per minute. But a new matchbook-sized motor runs circles around the competition.

Researchers from ETH Zurich’s Department of Power Electronics created a drive system in cooperation with its industrial partners that exceeded 1,000,000 rpm in tests.

Special Report: China expands amphibious forces in challenge to U.S. beyond Asia

Posted by in category: military

HONG KONG (Reuters) — China launched its military build-up in the mid-1990s with a top priority: keep the United States at bay in any conflict by making the waters off the Chinese coast a death trap. Now, China’s People’s Liberation Army (PLA) is preparing to challenge American power further afield.

China’s shipyards have launched the PLA Navy’s first two Type 075 amphibious assault ships, which will form the spearhead of an expeditionary force to play a role similar to that of the U.S. Marine Corps. And like the Marines, the new force will be self-contained — able to deploy solo with all its supporting weapons to fight in distant conflicts or demonstrate Chinese military power.

Battery Breakthrough to Give Flight to Electric Aircraft and Boost Long-Range Electric Cars

Posted by in categories: sustainability, transportation

New battery technology developed at Berkeley Lab could give flight to electric aircraft and supercharge safe, long-range electric cars.

In the pursuit of a rechargeable battery that can power electric vehicles (EVs) for hundreds of miles on a single charge, scientists have endeavored to replace the graphite anodes currently used in EV batteries with lithium metal anodes.

But while lithium metal extends an EV’s driving range by 30–50%, it also shortens the battery’s useful life due to lithium dendrites, tiny treelike defects that form on the lithium anode over the course of many charge and discharge cycles. What’s worse, dendrites short-circuit the cells in the battery if they make contact with the cathode.

Improved Advanced Energy Storage Using New Nano-Engineering Strategy

Posted by in categories: energy, engineering, nanotechnology, sustainability

New types of cathodes, suitable for advanced energy storage, can be developed using beyond-lithium ion batteries.

The rapid development of renewable energy resources has triggered tremendous demands in large-scale, cost-efficient and high-energy-density stationary energy storage systems.

Lithium ion batteries (LIBs) have many advantages but there are much more abundant metallic elements available such as sodium, potassium, zinc and aluminum.
