Characterization of low-temperature plasmas generated by dielectric barrier discharges for bacterial inactivation

Low-temperature plasmas (LTPs) at atmospheric pressure hold great promise for disinfection and sterilization applications. When compared to traditional sterilization technologies like autoclaving, LTPs may offer several benefits, including reduced energy c ...

Electrode Impact on the Electrical Breakdown of Dielectric Elastomer Thin Films

Herbert Shea, Fabio Beco Albuquerque

Dielectric Elastomer Actuators (DEAs) enable the realization of energy-efficient and compact actuator systems. DEAs operate at the kilovolt range with typically microampere-level currents and hence minimize thermal losses in comparison to low voltage/high ...

Secondary Fast Breakdown in Narrow Bipolar Events

Marcos Rubinstein, Dongshuai Li

The physical mechanism of Narrow bipolar events (NBEs) has been studied for decades but it still holds many mysteries. Recent observations indicate that the fast breakdown discharges that produce NBEs sometimes contain a secondary fast breakdown that propa ...

Memristive Biosensors based on Full-size Antibodies and Antibody Fragments

Giovanni De Micheli, Sandro Carrara, Ioulia Tzouvadaki, Sébastien Naus

For the first time memristive biosensors developed by the incorporation of scAbs (single-chain antibody fragments) enabling label-free detection of free Prostate Specific Antigen (fPSA) for early-stage detection of prostate cancer (PC) are reported. In add ...

Field Plate Design for Low Leakage Current in Lateral GaN Power Schottky Diodes: Role of the Pinch-Off Voltage

Elison de Nazareth Matioli, Jun Ma, Dante Colao Zanuz

In this letter, we demonstrate a general model to reduce the reverse leakage current (I-R) in high-voltage AlGaN/GaN Schottky diodes (SBDs) by engineering the pinchoff voltage (V-p) of their field plates (FPs). The maximum voltage drop at the Schottky junc ...

Deep-ultraviolet picosecond flat-top pulses by chirp-matched sum frequency generation

Christoph Peter Hauri

Picosecond, flat-top, deep-UV pulses are needed to generate high-brightness electron beams to efficiently drive x-ray free electron lasers. Current metal photocathodes have low efficiency and therefore require high-energy pulses, and the generation of high ...
