Simulation of the Electrostatic Distribution in the Proximity Focusing Structure of an EBCMOS
Published 2020-01-01Get full textThe electrostatic distribution of an electron bombarded CMOS (EBCMOS) was simulated by Ansoft Maxwell 3D software. Specifically, we studied how the electrostatic distribution was affected by the structure of a back-side bombarded CMOS (BSB-CMOS) and the anode position in electron-bombarded sensors....

Study on EGCG complex with Cu<sup>2+</sup>
Published 2004-05-01Get full textCopper ions easily complex with ligand and act as the central ion. EGCG ((—) Epigallocatechin gallate), one of the catechins in tea, is the most active natural polyphenol in the products and, being a polyligand, can complex with Cu<sup>2+</sup>. In this paper, the reaction condition for...

Study on the specific adsorption of catechin gallates by cedar lignocellulose
Published 2006-11-01Get full textLignocellulose was prepared from cedar sawdust and used to isolate caffeine and tea catechins from tea extract by static adsorption and gradient elution using water and 80% ethanol. The results showed that there were obvious different adsorption for tea caffeine and catechin gallates by the lignocel...

Research and application of digital measure management and control technology for characteristic low-efficiency gas wells in Gas Field A.
Published 2025-01-01Get full textGas Field A has entered the middle and late stages of development, with the number of low-efficiency wells increasing year by year. In the Songliao old area, extreme cold weather (-40°C) has led to 45% of gas wells experiencing freeze-offs. In the Sichuan-Chongqing exploration area, high formation w...
