Wafer-Scale MgB Superconducting Devices.

Progress in superconducting device and detector technologies over the past decade has realized practical applications in quantum computers, detectors for far-infrared telescopes, and optical communications. Superconducting thin-film materials, however, have remained largely unchanged, with aluminum still being the material of choice for superconducting qubits and niobium compounds for high-frequency/high kinetic inductance devices. Magnesium diboride (MgB), known for its highest transition temperature ( = 39 K) among metallic superconductors, is a viable material for elevated temperature and higher frequency superconducting devices moving toward THz frequencies.

Single-photon detection using large-scale high-temperature MgB sensors at 20 K.

Ultra-fast single-photon detectors with high current density and operating temperature can benefit space and ground applications, including quantum optical communication systems, lightweight cryogenics for space crafts, and medical use. Here we demonstrate magnesium diboride (MgB) thin-film superconducting microwires capable of single-photon detection at 1.55  μm optical wavelength.

Resin: Volatile Components and Impact on Plant Pathogenic and Foodborne Bacteria.

() produces a white, sticky, latex-like resin with antimicrobial properties. The aims of this research were to evaluate the effects of this resin ( resin) on bacterial populations and to determine the impact of its primary volatile components on bioactivity. The impact of sample treatment on chemical composition of resin was analyzed using Fourier transform infrared spectroscopy (FTIR) coupled with principal component analysis.
