‘Flying saucer’ quantum dots hold secret to brighter, better lasers

By carefully controlling the size of the quantum dots, researchers can ‘tune’ the frequency, or color, of the emitted light to any desired value. The ability to produce a laser of any desired frequency from a single material would give a boost to scientists looking to study diseases at the level of tissues or individual cells by offering new tools to probe biochemical reactions. They could also enable laser display projectors that would be brighter and more energy efficient than current LCD technology.

Unexpected, star-spangled find may lead to advanced electronics

Researchers have described a material that, when heated to about 450 degrees Celsius, transforms from an atomically thin, two-dimensional sheet into an array of one-dimensional nanowires, each just a few atoms wide. An image caught in mid-transformation looks like a tiny United States flag, and with false colors added, is arguably the world’s smallest image of Old Glory, researchers said.

Nano-polycrystalline film leads to stronger magnetism compared to single-crystal films

Nanoscale pillar-shaped distribution of iron in strontium titanate can change its magnetic and magnetooptical response drastically, say researchers. Surprisingly, the polycrystalline film on the silicon substrate showed stronger magnetism than a single crystalline film.

Research leads to a golden discovery for wearable technology

Researchers say they have developed a way to “grow” thin layers of gold on single crystal wafers of silicon, remove the gold foils, and use them as substrates on which to grow other electronic materials.
