IBM partnered with National Geographic Kids magazine to 'chisel' the world's smallest magazine cover ever. The recently certified GUINNESS WORLD RECORDS cover is 11 × 14 micrometers - at this size 2,000 could fit on a grain of salt.
After using it to develop a computer chip, flash memory device and photographic sensor, scientists have once again tapped into the electronic potential of molybdenite by creating diodes that can emit light or absorb it to produce electricity.
Just a few grams of the new substance are enough to tag the entire olive oil production of Italy. If counterfeiting were suspected, the nanoparticles added at the place of origin could be extracted from the oil and analysed, enabling a definitive identification of the producer.
School children learn the difference between liquids and gases, but centuries of scholarship have failed to produce consensus about how to categorize glass. Now, combining theory and numerical simulations, researchers have resolved an enduring question in the theory of glasses, showing that their energy landscapes are far rougher than previously believed. The new model shows that molecules in glassy materials settle into a fractal hierarchy of states.
A new AIP report, titled Physics Entrepreneurship and Innovation, is based on extensive interviews with 140 PhD physicists and other professionals who co-founded and work at some 91 startup companies in 14 states that were established in the last few decades. These companies are engaged in making medical devices, manufacturing tools, nanotechnology, lasers and optical devices, renewable energy technologies and other products.
