the interaction of hemin with chloroquine,quinine and quinidine was investigated in 50% water-propylene glycol mixture at pH=9,8.1,7.4 and 6.8using a spectrophotometric method.The data could be well fitted into a model consistent with the formation of a 1:1 complex between the reacting partners...
The application is to maintain the resistance of a closed loop coolant system of 80 gallons at a nominal 7 megohm cm. The coolant is either pure water or a mixture of water and laboratory grade Propylene Glycol. The parallel loop flow rate through the pod is 0.7 gpm and the inlet is at...
2.1. The liquid PEG + water mixture In the development of a molecular theory aiming to characterize the thermodynamic properties of PEG+ water mixtures, one has to be able to treat the chain-like nature of the polymer and the effects of hydrogen bonding. The most widely-employed theoretical ...

Highest selectivity of 281 with flux of 0.076 kg/m2h has been observed PVA/PSM blend membrane when compared to pristine PVA membrane to dehydrate 12.5 wt.% water in feed mixture. Flux values were decreased from 0.112 to 0.076 kg/m2h to dehydrate 12.5 wt.% water in feed mixture for PVA/...
In this study, we report on the properties of water + propylene glycol/sugar surfactant/peppermint oil + ethanol. The sugar surfactants were sucrose monola... M Fanun - 《Colloid & Polymer Science》 被引量: 30发表: 2009年 Olive oil microemulsions: enzymatic activities and structural characteris...
A bottom-up water-based solution-process method was developed for atomic layered MoS2 with a one-step annealing process and no sulfurization. The chosen MoS2 precursor is water soluble and was carefully formulated to obtain good coating properties on a s

As the leader of advanced fibrous materials, electrospun nanofibers combine the properties of tunable wettability, large surface area, high porosity, good connectivity, fine flexibility, and ease of scalable synthesis from various materials (polymer, ceramic, carbon, etc.), and they hold great ...
Finally, propylene glycol methyl ether acetone (PGMEA) is used as the developer. An ultrasonic agitator is used to increase the developing speed. The thickness of the SU-8 structure is determined by a profiler. The diameter and period of the posts are measured by a microscope. The PDMS ...
