Self‐Assembled Gallium Sulfide (GaS) Heterostructures Enabling Efficient Water Splitting and Selective Ammonia Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Gallium sulfide (GaS) forms self‐assembled heterostructures with its native oxide, exhibiting high performance in water splitting and ultrasensitive and selective ammonia detection. Surface defects and controlled oxidation enhance catalytic activity and sensing response.

The Hydrogen Atom

2020
We start with a brief classical description of the hydrogen atom including a supplementary section that reveals the hidden symmetry responsible in part for the incredibly simple structure of the energy spectrum of the hydrogen atom. Niel’s Bohr’s simple but incorrect derivation of the energy spectrum of the Hydrogen atom is then described. Although his

The Atomic Hydrogen Maser [PDF]

open access: possibleIRE Transactions on Instrumentation, 1961
The atomic hydrogen maser is described. In this device hydrogen atoms in the upper hyperfine state are focused onto the entrance aperture of a Teflon coated quartz bulb in which the atoms are stored for about a second. This bulb is surrounded by a cylindrical radiofrequency cavity; When the cavity is tuned to the hyperfine frequency of atomic hydrogen,
