Synthesis and surface-active property of bis-quaternary ammonium-sodium sulfate Gemini surfactant
      
For three tested samples, under UV illumination CCT01 has the highest activity for MB photocatalytic degradation, while in the case of RB, CCT02 is the most active photocatalyst.
      
The homopolymer and copolymers of Compound A with lactide or caprolactone have reaction-active groups and excellent biocompatibility and biodegradability; so they can be used in tissue engineering and as controlled-drug-release carriers.
      
Self-seeding nucleation, leading to a decrease in active energy for crystallization and chain folding work, promotes the overall crystallization process of PTT.
      
Compounds of 3-methyl-1-phenyl-4-{4-[(5-methyl-2-phenyloxazol-4-yl)methoxy]benzylene(benzyl)}-2-pyrazol-5-one were designed and synthesized to find some more hypoglycemic active agents and further investigate the SAR of this class of compounds.
      
Active sites on the surface of ITO are critical to the formation of the crystal nucleus and a uniform and compact CdS nano-film.
      
The active site and crystal nucleus are formed due to the comprehensive effect of electricity, thermodynamics and chemistry.
      
Consequently, Pd/Ni catalysts are much more active than Pd/Ni and Pd/c-Al2O3 with the same Pd loading prepared by the conventional impregnation method.
      
Results show that the apparent active energy E of the reaction is 105.51 kJ/mol, the frequency factor lnA is 3.602 and the reaction order n is 2.
      
In principle, when the motor runs in the 120° conduction mode, two of the three phases are active while the other phase is inactive at all times.
      
Active contour model based on force field analysis
      
Next, active contours have difficulties progressing into boundary concavities.
      
An active contour model based on force field analysis (FFA), namely, FFA snake model, is presented in this paper.
      
It effectively reduces the number of active nodes and extends the lifetime of the sensor network.
      
The active power P and the reactive power Q are obtained through the PQ transformation of the stator currents.
      
The content of water vapor in atmosphere is very little and the ratio of volume of moisture to air is about 0.1%-3%, but water vapor is the most active molecule in atmosphere.
      
This analytical approach applies H∞ optimization and internal model control (IMC) theory to design active queue management (AQM) routers that support transmission control protocol (TCP) flows.
      
AM inoculation also promoted the active and total absorption area of root system and absorption of phosphorus from the rhizosphere, enhanced the content of soluble sugar in leaves and roots, and reduced proline content in leaves.
      
The photosynthetically active radiation (PAR) and vapour pressure deficit (VPD) were the major factors influencing diurnal changes in sap flow, which explained 60%-74% variations in sap flow density for all species except Phellodendron amurense.
      
In addition, it is also revealed that by stepwise regression analyses photosynthetical active radiation (PAR), temperature and wind speed are the main environmental factors affecting sap flow velocity.
