Droplet combustion at high ambient pressures is studied numerically by formulating one dimensional combustion model in the mixture of n-heptane fuel and air. The ambient pressure is supercritical conditions. The modified Soave-Redlich-Kwong state equation is used in the evaluation of thermophysical properties to account for the real gas effect on fluid p-v-T properties in high pressure conditions. Non-ideal thermodynamic and transport property at near critical and supercritical conditions are also considered. Several parametric studies are performed by changing ambient pressure and initial droplet diameter. Droplet lifetime decreased with increasing pressure. Surface temperature increased with increasing pressure. Ignition time increased with increasing initial droplet diameter. Temporal or spatial distribution of mass fraction, mass diffusivity, Lewis number, thermal conductivity, and specific heat were presented.

In this study, we used a charge coupled device to measure scintillating and Cerenkov light generated in a scintillating fiber-optic radiation sensor irradiated by high-energy photon and electron beams. The intensities of Cerenkov light are measured and characterized as a function of the incident angles of the high-energy photon and electron beams from a clinical linear accelerator. To minimize or remove Cerenkov light, we investigated a subtraction method using a dummy optical fiber and a wavelength discrimination method using optical filters. Also, the intensities of Cerenkov light induced by high-energy photon and electron beams are compared.

We prepared activation-free copolymeric films with high selectivity to biomolecules by surface-initiated Activators ReGenerated by Electron Transfer Atom Transfer Radical Polymerization (SI-ARGET ATRP) by monomers such as N-acryloxysuccinimide (NAS) and oligo(ethylene glycol) methyl ether methacrylate (OEGMEMA). Subsequently the coupling of a biotin ligand was directly performed on poly(NAS-co- OEGMEMA) films without an activation step, resulting in biotinylated, poly(NAS-co-OEGMEMA) films. Micro-contact printing (μCP) of the biotin ligand on the poly(NAS-co-OEGMEMA) films and subsequent immersion the biotin-patterned films in rhodamine-conjugated streptavidin solution was performed for evaluating feasibility of selective bioconjugation, resulting in microarray of protein.
