Effects of Welding Time and Electrical Power on Thermal Characteristics of Welding Spatter for Fire Risk Analysis

Energies, 2020
To predict the fire risk of spatter generated during shielded metal arc welding, the thermal characteristics of welding spatter were analyzed according to different welding times and electrical powers supplied to the electrode.

Further developments and tests of microstrip gas counters with resistive electrodes [PDF]

arXiv, 2011
We present results from further tests of Microstrip Gas Counters (MSGCs) with resistive electrodes. The maim advantage of this detector is that it is spark-protected: in contrast to "classical" MSGCs with metallic electrodes, sparks in this new detector do not destroy its electrodes.

Influence of Form and Structural Features of Open‐Cell Hybrid Foam on the Remanent Magnetic Scanning

Advanced Engineering Materials, EarlyView.
Simulations using an equivalent model are performed to improve the understanding of remanent magnetic scanning of hybrid foam samples for coating thickness estimation. The model allows to study the influence of isolated geometrical features such as layer thickness, boundary effects, as well as effects due to the statistical nature of the foams, which ...

A novel dielectric elastomer actuator based on polyvinyl alcohol hydrogel electrodes [PDF]

arXiv, 2014
We firstly demonstrate physically-prepared compliant PVA hydrogel electrodes as a promising supplement in dielectric elastomer actuators. They are capable of conducting high voltages over 5 kV without electrolysis by an electrical double layer effect. The hydrogel electrodes adhere tightly to the dielectric layer, which ensures its structural stability

Direct observation of active material concentration gradients and crystallinity breakdown in LiFePO4 electrodes during charge/discharge cycling of lithium batteries

, 2014
The phase changes that occur during discharge of an electrode comprised of LiFePO4, carbon, and PTFE binder have been studied in lithium half cells by using X-ray diffraction measurements in reflection geometry. Differences in the state of charge between

Effect of the reference electrode size on the ionization instability in the plasma sheath of a small positively biased electrode [PDF]

, 2010
It is well known that additional ionization in the vicinity of a positively biased electrode immersed into a weakly ionized plasma is responsible for a hysteresis in the electrode current-voltage characteristics and the current self-oscillations rise.
