Mass spectra of neutral particles released during electrical breakdown of thin polymer films [PDF]
, 1985 A special type of time-of-flight mass spectrometer triggered from the breakdown event was developed to study the composition of the neutral particle flux released during the electrical breakdown of polymer films problem. Charge is fed onto a metal-backed

Advanced Engineering Materials, EarlyView.In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

Advanced Engineering Materials, EarlyView.Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

Impulse dielectric behaviour of dry air in sphere-plane gap
The Journal of Engineering, 2019 The dielectric strength of dry air is lower than that of SF(6), so it is very difficult to use dry air in extra-high-voltage-class gas-insulated equipment.

Statistical Analysis of AC Dielectric Strength of Natural Ester-Based ZnO Nanofluids
Energies, 2020 Due to environmental concerns and increased energy demand, natural esters are among the alternatives to mineral oils in transformers. This study examines the electrical behavior of natural ester-based ZnO nanofluids at different concentrations in the ...

Advanced Engineering Materials, EarlyView.Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

Reducing bubbles in glass coatings improves electrical breakdown strength [PDF]
, 1968 Helium reduces bubbles in glass coatings of accelerator grids for ion thrustors. Fusing the coating in a helium atmosphere creates helium bubbles in the glass.

Advanced Engineering Materials, EarlyView.The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,
