Influence of ageing on oil degradation and gassing tendency under high-energy electrical discharge faults for mineral oil and synthetic ester

High Voltage, 2020
In this work, mineral oil and synthetic esters were selected at different ageing factors (based on acidity values). Fresh and aged oils have been subjected to high-energy discharges (repeated 100 breakdowns) to simulate electric faults of highly ...

Investigation of work function and chemical composition of thin films of borides and nitrides [PDF]

, 2018
Thin films of various borides, nitrides, and barium fluorides were tentatively deposited by pulsed laser deposition and by magnetron sputtering in order to develop the components of thermionic-photovoltaic devices for the high-temperature thermal to ...

Vibrationally Resolved Absorption and Fluorescence Cross Sections of Adamantane in the Far-ultraviolet Spectral Range on an Absolute Scale

The Astrophysical Journal Supplement Series, 2023
High-resolution absorption, dispersed fluorescence emission, and photoionization cross sections are presented for gas-phase adamantane excited by synchrotron radiation in the exciting-photon energy range of 6–30 eV. Relative and absolute absorption cross

Femtosecond Spectroscopy with Vacuum Ultraviolet Pulse Pairs [PDF]

, 2010
We combine different wavelengths from an intense high-order harmonics source with variable delay at the focus of a split-mirror interferometer to conduct pump-probe experiments on gas-phase molecules. We report measurements of the time resolution (

Ultraviolet spectroscopy of narrow coronal mass ejections [PDF]

, 2003
We present Ultraviolet Coronagraph Spectrometer (UVCS) observations of 5 narrow coronal mass ejections (CMEs) that were among 15 narrow CMEs originally selected by Gilbert et al. (2001). Two events (1999 March 27, April 15) were "structured", i.e.

Determination of desulpho-glucosinolates in bolting stems of Chinese kale by liquid chromatography-mass spectrometry

浙江大学学报. 农业与生命科学版, 2008
The crude glucosinolates (GSs) were extracted from bolting stems of Chinese kale (Brassica alboglabra) and purified by a column packed with DEAE Sephadex A-25. The desulpho-glucosinolates were obtained after desulfurizing of GSs by sulfatase.
