Highly Anisotropic Suspended Planar-Array Chips with Multidimensional Sub-Micrometric Biomolecular Patterns
The physical and chemical properties of silicon chips can be tuned to address the requirements of the research. The control of the physical anisotropy from fabrication allows obtaining chips with the desired aspect ratio, branching, faceting and size.
Thermal Phase Lag Heterodyne Infrared Imaging for Radio Frequency Integrated Circuits Performance Degradation Analysis
With thermal phase lag measurements, current paths are tracked in a Class A Radio Frequency (RF) power amplifier at 2 GHz. The phase lag maps evidence with a higher sensitivity than thermal amplitude measurements, an input-output loop due to a substrate capacitive coupling.
P-GaN HEMTs Drain and Gate Current Analysis under Short-Circuit
Gallium Nitride High-Electron-Mobility Transistors (GaN HEMTs) are promising devices for high-frequency and high-power density converters, but some of their applications (e.g., motor drives) require high robustness levels.
Short-Circuit Study of Medium Voltage GaN Cascodes, P-GaN HEMTs and MISHEMTs
This paper studies by experimentation and physics-based simulation the Short-Circuit (SC) capability of several normally-off 600-650 V Gallium Nitride High-Electron-Mobility Transistors (GaN HEMTs): cascodes, p-GaN, and GaN Metal-Insulator-Semiconductor HEMTs (MISHEMTs).
Robust L-malate bienzymatic biosensor to enable the on-site monitoring of malolactic fermentation of red wines
The development of an amperometric biosensor for L-malate determination showing long-term stability is reported in this work.
Solid contact ion sensor with conducting polymer layer copolymerized with the ion-selective membrane for determination of calcium in blood serum
A new solid contact ion selective electrode with intermediate conducting polymer (CP) layer formed by electropolymerization on a gold electrode of a bifunctional monomer, n-phenyl-ethylenediaminemethacrylamide (NPEDMA), which contains a methacrylamide group attached to aniline, is presented.
Impedimetric antimicrobial peptide-based sensor for the early detection of periodontopathogenic bacteria
The aim of the present study was to combine the use of miniaturized and integrated impedimetric transducers and antimicrobial peptide AMPs to obtain biosensors with high sensitivity to monitor bacterial colonization to prevent implant-related infections..
Multiple actuation microvalves in wax microfluidics
A new type of electrically controlled and fully integrated wax microvalve is described in this work. The valve is designed for multiple actuation and has a small footprint (< 0.5 mm2), fast response (< 0.3 s) and low energy consumption (< 35 mJ).
Polysilicon-chromium-gold intracellular chips for multi-functional biomedical applications
In this work, the feasibility of using multi-material pSi-Cr-Au intracellular chips for multifunctional applications by characterizing their interactions with two different cell lines, one tumorigenic and one non-tumorigenic has been explored.
Study From Cryogenic to High Temperatures of the High- and Low-Resistance-State Currents of ReRAM Ni–HfO2–Si Capacitors
Resistive switching conduction in Ni/HfO2/Si capacitors is studied at temperatures ranging from 77 to 473 K. A model for the low-resistance state (LRS) consistent with the experimental data is proposed.
