Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Plasma heating from alpha particle micro-instabilities [PDF]

, 1981
Potential use of thermonuclear (i.e., fusion product) driven kinetic instabilities to heat the background plasma has long been recognized. Considerable research on velocity space micro-instabilities exists.

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

Modeling complex plasma instabilities in space plasmas

Astronomy & Astrophysics
Context. Despite the fact that electrons observed in situ in space plasmas have three major components – the quasi-thermal core, suprathermal halo, and strahl – the analysis of instabilities triggered by kinetic, velocity-space anisotropies (such as ...

The general dispersion relation of induced streaming instabilities in quantum outflow systems

AIP Advances, 2015
In this manuscript the dispersion relations of streaming instabilities, by using the unique property (neutralized in charge and current by default) of plasma shells colliding, have been generalized and studied.

Experimental Control of Plasma Instabilities

, 2004
A review is given of active control of plasma instabilities in a number of different experimental configurations. Starting with the control of global oscillations in simple plasma diodes, the more demanding problem of wave-type plasma instabilities is ...

Raman and two‐plasmon decay instabilities in a magnetized plasma

, 1984
The effects of a magnetic field on the Raman and two‐plasmon decay instabilities are studied in the region of the quarter‐critical density of laser produced plasmas where both are coincident.

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a
