Observational Evidence of Negative Leader Reactivation Processes Following a Negative Return Stroke in Lightning Discharges

Geophysical Research Letters
High‐time‐resolved mapping results of two rare reactivation processes following a negative return stroke are discovered and analyzed. The reactivation processes can be roughly divided into two different stages.

Electric discharge during electrosurgery [PDF]

Scientific Reports, 2015
Abstract Electric discharge utilized for electrosurgery is studied by means of a recently developed method for the diagnostics of small-size atmospheric plasma objects based on Rayleigh scattering of microwaves on the plasma volume.

Measuring of electric fields with laser-induced fluorescence-dip Stark spectroscopy

, 2007
The electric field is an important quantity in low-pressure gas discharges, driving many fundamental processes. Unfortunately, it is difficult to measure electric field distributions in plasmas directly.

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Observing the neutron component during thunderstorm activity at a mountain CR station

Solar-Terrestrial Physics, 2019
During three summer months in 2015, the Cosmic Ray (CR) station Irkutsk-3000, located at 3000 m above sea level, measured the CR neutron component intensity with the 6NM64 neutron monitor, as well as the atmospheric electric field strength and the level ...

Partial Discharge Behaviour within Two Spherical Cavities in a Dielectric Material [PDF]

, 2011
In high voltage insulation systems, a typical defect that exists is a void cavity. It is known that voids are a common source of partial discharge (PD) activity within an insulation system.

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.

Evaluation of Plasticity and Creep Parameters From Tensile Stress–Strain Data for a Range of Strain Rates

Advanced Engineering Materials, EarlyView.
This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.
