A new fabrication method for quantum dots could lead to more effective and efficient quantum dot displays, especially due to improvements in the generation of blue-colored quantum dots. The process has been called a “bottom-up, self-organizing chemistry” by its designer, Dr. Eiichi Nakamura of Tokyo University.

One of the most challenging aspects of developing self-driving cars, particularly for vehicles that will be used in environments with mixed autonomous and manually operated vehicles, is developing sensor systems that can deal with the range of distances, weather, and light conditions that the vehicle will be exposed to.

Photoelectron spectroscopy involves the detection of the kinetic energies of photoelectrons emitted following an ionization event. If it is assumed that the emitted photoelectrons do not undergo any collisional event post-ionization, the kinetic energy of the detected electron should be equal to the binding energy of the orbital it was ejected from.

Mass spectrometry is an analytical technique used for chemical identification. By ionizing and fragmenting the sample of interest and measuring the mass-to-charge ratios of the products formed, it is possible to see a ‘chemical fingerprint’ that can help work out a chemical structure. Mass spectrometry can also be used to identify unknown compounds.

Diffuse reflectance spectroscopy is a type of absorption spectroscopy where, rather than measuring the transmitted beam through the sample, the light reflected from the sample is measured instead. It is a common method for measuring opaque samples that absorb too strongly to be measured in transmission.
