Differential scanning calorimetry (DSC) is an analytical technique that measures the molar heat capacity of samples as a function temperature. In case protein samples, DSC profiles provide information about thermal stability, and to some extent serves structural "fingerprint" can be used assess conformation. It performed using differential calorimeter transition temperature (melting temperature; Tm) energy required disrupt interactions stabilizing tertiary structure (enthalpy; ∆H) proteins....
A core chip of optofluidic variable optical attenuator (VOA) is reported. The chip, with a simple structure, utilizes microfluid and compressed air to regulate the attenuation, it can be expanded form number VOAs by using different microfluidic driving technologies. Three based on this technologies are introduced. theoretical experimental results show that proposed possesses advantages large attenuation range (> 50dB) low insertion loss (0.55 dB). Moreover broadband device which operated in...
This paper presents a miniaturized tunable bandpass filter, consisting of two coaxial dielectric resonators and pair parallel-coupled lines. A microstrip line form new step-impedance resonator (SIR), which is different from conventional SIR. Varactor diodes are connected to SIRs tune the center frequency. The gap between lines controls inter-stage coupling coefficient. Lumped inductors used for I/O ports can reduce design complexity. variations coefficient external quality factor with tuning...
Second-order coaxial dielectric ceramics filters with one or two transmission zeros (TZs) have been presented. The TZs are analyzed in detail. results showed that source and load can be regarded as virtual resonators, resonators of a second-order filter together form four-resonator known the CQ, resonator forms three section CT. A chip capacitor (0.5PF) is used cross-coupling elements. filters, made monoblock constant 75, were fabricated measured, which produced both above below passband,...
In present work, the characteristics of bubble growth and frequency were visually observed in a narrow rectangular channel using high-speed digital camera. The experiment was done over following range conditions: pressure, 0.55MPa; mass flux, 300–500kg/(m2·s); heat 86.4–225.7 kW/m2; inlet subcooling, 25.5–45.5K. system pressure has significant effect on growth. Experimental results show that diameters are just about 0.15mm under higher period during which bubbles attaching to nucleate site...
