LDPE Surface Modifications Induced by Atmospheric Plasma Torches with Linear and Showerhead Configurations [PDF]

Plasma Processes and Polymers, Wiley-VCH Verlag, 2015, 12 (8), pp.771-785, 2016
Low density polyethylene (LDPE) surfaces have been plasma modified to improve their nanostructural and wettability properties. These modifications can significantly improve the deposition of subsequent layers such as films with specific barrier properties.

Flexible Production of Spherical Powders of Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W Refractory High‐Entropy Alloys by Plasma‐Assisted Centrifugal Atomization

Advanced Materials Technologies, EarlyView.
In this work, spherical powders of refractory Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W high‐entropy alloys (R‐HEAs) have been fabricated in a single step by plasma‐assisted centrifugal atomization. Loss of the heaviest elements in the composition is observed only at rotational speeds higher than 13 000 rpm due to solid‐solid centrifugal separation.

Influence of ambient air on the flowing afterglow of an atmospheric pressure Ar/O2 radiofrequency plasma [PDF]

Journal of Applied Physics, American Institute of Physics, 2013, 113 (9), pp.093303, 2016
The influence of ambient air on the flowing afterglow of an atmospheric pressure Ar/O2 radiofrequency plasma has been investigated experimentally. Spatially resolved mass spectrometry and laser induced fluorescence on OH radicals were used to estimate the intrusion of air in between the plasma torch and the substrate as a function of the torch-to ...

Biological and Mechanical Limitations for Chronic Fast‐Scan Cyclic Voltammetry Sensor Design

Advanced Materials Technologies, EarlyView.
Real‐time detection of neurochemicals has demonstrated value in the field of neuroscience. However, current methods have limitations for use in the chronic setting, which is often the ideal environment for research. This article discusses these limitations, as well as technologies that have been developed to overcome them, and provides recommendations ...

Functional Optical Fibers with Tailored Side Emission from Modified Rod‐in‐Tube Preforms

Advanced Photonics Research, EarlyView.
A modified rod‐in‐tube method enables fabrication of functional optical fibers with tailored light‐diffusing properties. The approach incorporates optically active species at a well‐defined radial position within an otherwise homogeneous fiber core. Using lanthanide ions and noble metal nanoparticles as active species demonstrates wavelength conversion
