Water light transmittance

Vent fields have been discovered in numerous ways, but surveys of the overlying water column and camera tows are the most common systematic approaches employed today. The venting of hot/warm water often forms a plume with unique temperature, salinity, reduced light transmittance, and other specific chemical signals several hundred meters above the ridge. The presence of such a plume is often the first indication that a given section of ridge is hydrothermally active. Cameras, or other... 

The morphology, order, light transmittance and water vapor permeability of the A1 coated polypropylene films were reported in a previous publication [17], The films did not transmit light in tlie UV and visible region of the light spectrum and A1 coating reduced the water vapor permeation through the films [17],...

Important relationships between formation of these functional groups and the fibrillation yield, light transmittance of the water dispersions and degree of polymerization of the oxidized softwood and hardwood pulps were estabhshed (43). The dependence of the yield of fibrillation on the content of carboxylate in TEMPO oxidized pulps is shown in Figure 5.6. 

The PDMAEMA-fe-Cso with a M of 18000 Da also exhibited both pH- and temperature-responsive properties [83]. The LCST of PDMAEMA-b-C ) determined from light transmittance (UV/vis) was -45 °C. However, the Hght transmittance of PDMAEMA-l)-Ciso was independent of pH at low temperatures but dependent on pH at high temperatures. At 55 °C, the PDMAEMA-fe-C6o became water-insoluble at pH >7.8. Laser-light scattering studies of PDMAEMA-fe-C6o in aqueous solutions at different temperatures and pH indicated that the... 

FIGURE 8.18 The profile of light transmittance of the second coagulation bath containing water. The cast films have been immersed in the first bath containing 40%, 60%, and 100% TEP/DMA in the ratio 40 60. The initial PVDF/TEP/DMA ratio of the polymer solution was 15/51/34. (Data from Li, Q. et al., Polymers for Advanced Technologies, 22, 520-531, 2011. doi 10.1002/pat.l549.)... 

Some physical and transport properties of the pristine polypropylene film (PP) and the chemically surface modified film (smPP) are listed in Table 1. After the surface treatment, the light transmittance of the pristine PP film was reduced about 16%, and both wettability and water permeation decreased [7].
