Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials. Now scientists from 香蕉视频 have developed a gentler, more precise technique using low-power visible light.
Research from 香蕉视频 topped 鈥檚 annual list of the 10 most important scientific breakthroughs. This year, G眉nther Grill, Bernhard Lehner, Tomislav Fri拧膷i膰, Heidi M. McBride, Samantha Gruenheid, and Ehab Abouheif were recognized for their trailblazing work, by a jury of researchers and journalists reviewing the most influential discoveries made in Quebec.
Here is a closer look at the selected discoveries:
Imagine a waterproof computer. It鈥檚 not going to happen tomorrow, but it may no longer be a pipedream since a McGill-led international research team has shown for the first time that it is possible to form strong, stable attractions between some of the heavier elements in the periodic table.
Professor is the recipient of the prestigious for his exceptional contributions to Green Chemistry research in Canada. He is the third McGill professor to win the Steacie Prize, and the first ever McGill professor to win it for chemistry. The two previous winners from McGill are Vicky Kaspi, Physics and Astronomy (2006) and Phil Gold, Medicine (1973).

Rare minerals from Siberia found to have same structure as some man-made metal-organic frameworks
One of the hottest new materials is a class of porous solids known as metal-organic frameworks, or MOFs. These man-made materials were introduced in the 1990s, and researchers around the world are working on ways to use them as molecular sponges for applications such as hydrogen storage, carbon sequestration, or photovoltaics.
The research group of Prof. Tomislav Fri拧膷i膰 in McGill鈥檚 Department of Chemistry has made a name for itself in the little-known, but growing field of 鈥渕echanochemistry,鈥� in which chemical transformations are produced by milling, grinding or shearing solid-state ingredients 鈥� brute force, in other words, rather than fancy liquid agents. 鈥淵our coffee maker grinds things,鈥� and grinding molecules in the lab involves much the same principle, Fri拧膷i膰 notes. Using mechanical force also has the significant advantage of avoiding the use of environmentally harmful bulk solvents.
