Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Hardness determination of bio-ceramics using laser-induced breakdown spectroscopy. [PDF]

, 2011
Laser-Induced Breakdown Spectroscopy (LIBS) was applied to the analysis of bioceramic samples. The relationship between sample hardness and LIBS plasma properties was investigated, with comparison to conventional Vickers hardness measurements.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Experimental Investigations of Magnetohydrodynamic Plasma Jets [PDF]

, 2009
This thesis primarily focuses on understanding the plasma behavior during the helicity injection stage of a pulsed spheromak experiment. Spheromak formation consists of a series of dynamic steps whereby highly localized plasma near the electrodes evolves

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

Advanced 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.

Charge resolved electrostatic diagnostic of colliding copper laser plasma plumes [PDF]

, 2011
The collision of two laser generated plasma plumes can result, under appropriate conditions, in the formation of ‘stagnation layer’. The processes underlying this phenomenon are complex and time dependent.

Observation of plasma confinement in picosecond laser-plasma interactions

Physical Review E, 1993
Novel features associated with multiterawatt laser interactions with solid targets at incident irradiances in the range (1.0--12.0)\ifmmode\times\else\texttimes\fi{}${10}^{17}$ W ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}2}$ are presented. Collimation of the plasma flow normal to the target surface has been observed in time-integrated x-ray images and ion-
