Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Optimisation of short pulse multi-stage Yb fiber amplifier systems using commercial gain-modelling software

open access: yes, 2006
We demonstrate the accuracy of commercial telecommunications industry software for modelling Yb-fiber amplifiers. Simulations enabled optimisation of a broad bandwidth ultra-short pulse four-stage amplifier system. The predicted results were confirmed by

Modeling electrical stimulation of retinal ganglion cell with optimizing additive noises for reducing threshold and energy consumption

open access: yesBioMedical Engineering OnLine, 2017
Background Epiretinal prosthesis is one device for the treatment of blindness, which target retinal ganglion cells (RGCs) by electrodes on retinal surface. The stimulating current of epiretinal prosthesis is an important factor that influences the safety

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

open access: yesAdvanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Trigonometric functions-based gaussian-like shaping algorithms for nuclear signals

open access: yesHe jishu
BackgroundGaussian shaping is commonly used to filter and extract the amplitude of nuclear pulse signals owing to its high signal-to-noise ratio, resistance to ballistic loss, and ease of amplitude extraction.

Acoustic analysis methods for particle identification with superheated droplet detectors [PDF]

open access: yesE3S Web of Conferences, 2019
A superheated droplet detector (SDD) consists of a uniform dispersion of over-expanded, micrometric-sized halocarbon droplets suspended in a hydrogenated gel, each droplet of which functions as a mini-bubble chamber.

Fiber-laser-generated Noise-like Pulses and Their Applications

open access: yes, 2016
We describe generation and amplification of mediumand high-energy noise-like pulses (NLPs) using Yb-doped optical fibers. We also demonstrate supercontinuum (SC) genera‐ tion techniques in which NLPs serve as the pump. SC pumped by NLPs has been em‐ ployed successfully in optical coherence tomography systems.
