Controlled Microwave Heating Accelerates Rolling Circle Amplification
Rolling circle amplification (RCA) generates single-stranded DNAs or RNA, and the diverse applications of this isothermal technique range from the sensitive detection of nucleic acids to analysis of single nucleotide polymorphisms. Microwave chemistry is widely applied to increase reaction rate as well as product yield and purity. The objectives of the present research were to apply microwave h...

متن کاملOptical amplification and pulse interleaving for low-noise photonic microwave generation.
We investigate the impact of pulse interleaving and optical amplification on the spectral purity of microwave signals generated by photodetecting the pulsed output of an Er:fiber-based optical frequency comb. It is shown that the microwave phase noise floor can be extremely sensitive to delay length errors in the interleaver, and the contribution of the quantum noise from optical amplification ...
متن کاملBREAKDOWN AND HIGH-FIELD RELIABILITY ISSUES IN HETEROJUNCTION FETs FOR MICROWAVE POWER AMPLIFICATION
High-field reliability issues connected with hot electron and impact ionization are typically the reliability bottleneck of power FETs for microwave and millimeter-wave applications. This work deals with some aspects of this problem, from characterization and accelerated stressing techniques to the physical degradation mechanisms, using power AlGaAs/GaAs HFETs as a test vehicle.
متن کاملConditions for microwave amplification due to spin-torque dynamics in magnetic tunnel junctions
Spin torque from a microwave current flowing through a magnetic tunnel junction (MTJ) can excite resonant magnetic dynamics and hence resistance oscillations. When a DC current is also applied, the MTJ produces an oscillating voltage at the frequency of the input signal. This oscillating voltage increases with DC bias and can in principle become larger than the input signal, yielding amplificat...
