Thermoelectric Effect of YBa ₂ Cu ₃ O _7-δ Films with Risetime of 0.6 Nanosecond

Abstract

Voltage pulses o f 90 V have been observed in YBazCuQOT--6 films with a tilted orientation when they are illuminated by pulsed laser at room temperature. The signals result from the anisotropy o f thermoelectricity in the films. The thermoelectric signals related to the tilted angle are linear to the laser power and wavelength-independent. It is shown that the response of films to the mode-locked laser has a risetime less than 1 ns and width less than 20ns. The films with the superconducting transition temperature o f 90K were prepared by'laser ablation.

RGD‐containing trypsin with both platelet aggregation inhibitory activity and proteolytic activity

“…The hydrolysis of TAME by trypsin releases H + which causes the pH decrease of the assay [ 11 ]. A method for trypsin activity assay was thus established as described below.…”

Utilizing the Transverse Thermoelectric Effect of Thin Films for Pulse Laser Detection

“…where ∇T z is the temperature gradient along film thickness direction, l is the irradiation length, and d is thickness of thin film [8,[12][13][14][15][16]. However, most of the previous studies on the TTE-based laser detectors just focused on the enhancement of voltage sensitivity, and less attention has been paid to the response speed.…”
