Quantitation of the level of specific mRNA involves the isolation of total RNA or poly(A)+ RNA as a starting material. Thus, this result is the sum of the transcription and degradation of mRNA. Here we report a rapid, sensitive, and high-throughput m

Emission of ultrashort electromagnetic pulses from current-biased superconducting YBCO films has been observed by exciting with femtosecond laser pulses. The emission device is made of YBCO strip lines with a bridge at their center on an MgO substrat

We observed a femtosecond time-transient nonequilibrium state in optically excited YBCO thin films for the first time. Ultrashort electromagnetic pulses were radiated from the films by an ultrafast supercurrent modulation with fs laser pulse irradiat

Surface flattening of YBCO films with Ar ion beam exposure was studied. Atomic force microscopy (AFM) observation revealed that the surface roughness decreases with increasing ion beam exposure time. The mechanism of flattening was explained by the a

Ultrashort electromagnetic waves (600 fs width) from superconducting YBCO thin films have been observed by irradiating current‐biased samples with femtosecond optical laser pulses (80 fs width). The Fourier component of the pulse extends up to ∼2

We demonstrate the emission of sub-picosecond electromagnetic waves from YBa2Cu3O7-δ thin-film bow-tie antennas. Femtosecond laser-pulse irradiation creates a radiative supercurrent transient in the films, and freely propagated radiation is detected

We have observed ultrashort electromagnetic pulse radiation from YBa2Cu3O7-δ thin-film dipole antennas. The supercurrent transient is created by the excitation of the supercarriers into quasiparticles with a femtosecond laser pulse, and freely propa
