MKID development for SuperSpec: an on-chip, mm-wave, filter-bank spectrometer [PDF]

, 2012
SuperSpec is an ultra-compact spectrometer-on-a-chip for millimeter and submillimeter wavelength astronomy. Its very small size, wide spectral bandwidth, and highly multiplexed readout will enable construction of powerful multibeam spectrometers for high-

Modification of boron nitride nanocages by titanium doping results unexpectedly in exohedral complexes

Nature Communications, 2019
Although isolated experimentally, the molecular structures of metal-containing boron nitride cages are still unknown. Here the authors show via DFT calculations that externally bound complexes of boron nitride fullerenes doped with a single titanium atom
