Having recently read S J Parris’s novel Alchemy, set in 16th century Prague, and finding myself in the Czech capital on a ...

Generally, both radial magnetic bearing stators and combination (radial and thrust) magnetic bearing stators are distributed in radial space. Besides, most magnetic bearings operate with additional ...

Varying the position of a reaction vessel on a magnetic stirrer can significantly change the outcome of a chemical reaction. That’s the conclusion of scientists working with Valentine Ananikov from ...

Stacked conical ring dielectric resonator antennas (DRA) excited by an axi-symmetric coaxial monopole are investigated numerically and experimentally for improved bandwidth. The bandwidth improvement ...

We investigate the properties of finite gold nanocones as optical antennas for enhancing molecular fluorescence. We compute the modification of the excitation rate, spontaneous emission rate, and ...
