Ram-wake effects on plasma current collection of the PIX 2 Langmuir probe [PDF]

open access: yes, 1985
The Plasma Interaction Experiment 2 (PIX 2) Langmuir probe readings of the same polar magnetospheric regions taken on consecutive orbits showed occasional apparent densities as much as 10 times lower than the average, although each pass clearly showed ...

Electroactive Metal–Organic Frameworks for Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
Electrocatalysis is crucial in sustainable energy conversion as it enables efficient chemical transformations. The review discusses how metal–organic frameworks can revolutionize this field by offering tailorable structures and active site tunability, enabling efficient and selective electrocatalytic processes.

Design and operation of a high-heat flux, flush-mounted ‘rail’ Langmuir probe array on Alcator C-Mod

open access: yesNuclear Materials and Energy, 2017
A poloidal array of toroidally-extended, flush-mounted ‘rail’ Langmuir probes was recently installed on Alcator C-Mod's vertical target plate divertor. The aim was to investigate if a Langmuir probe array could be designed to survive reactor-level heat ...

Angular dependence measurements of Magnum-PSI plasmas using MAST-U angled-tip Langmuir probes

open access: yesNuclear Materials and Energy, 2021
Measurements made using flush-mounted Langmuir probes in tokamaks are difficult to interpret when operating at grazing angles of magnetic field incidence due to the effects of sheath expansion on the probe collection area.

Three‐Dimensional Hierarchical Nanowire‐Networks with Deep‐Focus Tolerance and Adhesion Robustness for Harsh‐Environment SERS Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Multi-detection and polarisation contrast in scannning near-field optical microscopy in reflection [PDF]

open access: yes, 1995
A new type of NSOM probe has been developed, with a design based o­n the probes used in Atomic Force Microscopy. The probe consists of a cantilever with at its end a conical tip. This tip has been metal-coated to provide an aperture.

Designing Asymmetric Memristive Behavior in Proton Mixed Conductors for Neuromorphic Applications

open access: yesAdvanced Functional Materials, EarlyView.
Protonic devices that couple ionic and electronic transport are demonstrated as bioinspired neuromorphic elements. The devices exhibit rubber‐like asymmetric memristive behavior with slow voltage‐driven conductance increase and rapid relaxation, enabling simplified read–write operation.

Investiycrtion of electron temperature and density of laser-induced-plasma by Langmuir probe up to the centimeters scale distance from the target [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2015
In this paper, electron temperature and ion density of laser-produced plasma in the nanosecond time scale at different ambient gas pressures are studied using single Langmuir probe up to distances of the order of centimeter. The plasma is produced due to

Characteristics of the Plasma Source for Ground Ionosphere Simulation Surveyed by Disk-Type Langmuir Probe [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2017
A space plasma facility has been operated with a back-diffusion-type plasma source installed in a mid-sized vacuum chamber with a diameter of ~1.5 m located in Satellite Technology Research Center (SaTReC), Korea Advanced Institute of Science and ...
