Models from big molecules captured in a flash

(Phys.org) —To learn how biological molecules like proteins function, scientists must first understand their structures. Almost as important is understanding how the structures change, as molecules in the native state do ...

Testing the performance of semiconductors—with light

Semiconductors are the cornerstone of modern electronics. They're used in solar cells, light emitting diodes (LEDs), microprocessors in laptops and cell phones, and more. Most of them are made of silicon, but silicon has ...

Long-wavelength laser will be able to take medicine fingerprints

A laser capable of working in the terahertz range – that of long-wavelength light from the far infrared to 1 millimetre – enables the 'fingerprint' of, say, a drug to be examined better than can be done using chemical ...
