Temperature knowledge may be beneficial to improve the outcomes of thermal treatments for tumor ablation. Among several thermometric methods, contactless approaches based on diagnostic imaging techniques are attractive for this field. Computed Tomography (CT) images are sensitive to temperature, so some groups of research are working to assess the feasibility of CT-based thermometry for monitoring...
Spin Transfer Torque Magnetic Random Access Memory (MRAM) possesses a unique combination of high speed, high endurance, non-volatility, and small cell size. Among the emerging new memory technologies, including phase change memory, resistive random access memory, and conductive bridging random access memory, Spin Transfer Torque MRAM is the only candidate with the potential for unlimited endurance,...
We have investigated the basic plasma density and electron tempereature by using the collisional radiative model, and also investigated the reactive radical species's densities for hydroxyl OH, superoxide anion O2*− and nitric oxide NO by using the ultravilioet absorption spectroscopy with the deuterium lamp in the atmospheric pressure nonthermal argon bioplasma sources bombarding the water surface...
Internal and external quantum efficiency and injection efficiency of nitride-based UV/DUV devices were investigated. Non radiative component in the photoluminescence and electroluminescence is found to be strongly correlated with the dislocation density.
We report our experimental setup for the shot noise thermometry system at KRISS. Precision RF measurement setup in the frequency range of about 1 GHz has been installed in a He-3 refrigerator, which can be cooled down to 300 mK. The shot noise of Al-AlOx-Al tunnel junction, fabricated by two angle- evaporation technique, was measured and compared with theoretical curve. The inferred temperature from...
The dynamics of diatomic ligands such as O2, CO, and NO binding to ferrous (Fe2+) heme iron of myoglobin have been studied widely due to the physiological importance of reversible binding. However, the dynamics of NO with ferric (Fe3+) heme iron of myoglobin is not much studied due to the high reactivity of the heme iron toward NO. The appearance of the multiple bands at 1914, 1927, and 1942 cm-1...
This paper describes a miniaturized oxygen sensor array integrated with heaters and temperature sensors and a LabVIEW-based measurement system which exactly can measure a cellular respiration level in a solution containing cells simultaneously. The designed oxygen sensor consists of Clark-type sensors, heaters, and temperature sensors of 2 times 3 array type on the substrate. 18 mum PDMS was used...
