Preparation of rosin-based polymer microspheres as a stationary phase in high-performance liquid chromatography to separate polycyclic aromatic hydrocarbons and alkaloids
rosin-based stationary phase alkaloids polycyclic aromatic hydrocarbons polymer microspheres
2024/3/8
Acrylpimaric acid ethylene glycol acrylate was used as the cross-linking agent to prepare rosin-based polymer microspheres through membrane emulsification-microsuspension polymerization. The prepared ...
THE IDENTIFICATION OF DATA PRIMITIVES TO SEPARATE THE CONCEPTS AND SEMANTICS OF LAND COVER AND LAND USE:THE EXAMPLE OF ‘FOREST’
land use land cover primitives semantics text mining
2015/9/28
This paper is concerned with data and classifications that confuse the concepts of land cover and land use. Conceptual confusion is problematic for data integration and modelling. This has resulted in...
Separate Control of High Frequency Electro-hydraulic Vibration Exciter
control valves electro-hydraulic system vibration exciter
2011/8/3
The working frequency of the conventional electro-hydraulic vibration exciters, which consist of a servo valve and a hydraulic cylinder, is generally restricted within a narrow range due to limited fr...
Analysis of thermal conditions of pulse operated single quantum well separate confinement heterostructure (SQW SCH) lasers
junction temperature dynamics laser
2011/4/27
Junction temperature affects laser diode performance in many ways. Magnitude of the light output power, a center wavelength of the spectrum and diode reliability are all strongly dependent on the junc...
