beverage emulsions are systems that are composed of two liquids including oil and water which are prepared by homogenizing oil phase in an acidic aqueous phase. they must be stable in both concentrated and diluted form for a period of 6-12 months upon standing at room temperature. two immiscible phases contained systems are thermodynamically unsta-ble. in other words, they are vulnerable to bre...

introduction: colored compounds which often are toxic and carcinogen is one of the environmental pollutants. these pollutants should be removed prior than discharge to the environment. the aim of this study was the evaluation of maize tassel powder efficiency for the removal of reactive red 198 dye from synthetic textile wastewater. materials & methods: this experimental study was performed in ...

Banana peel is one of the wastes that can pollute environment so it needs to be utilized. One ingredients in kepok banana peels starch (carbohydrates). converted into glucose by hydrolysis method. This study aimed find out effect suspension levels on reaction kinetics process. The process used 2 N oxalic acid with times 10, 20, 30, 40 and 50 minutes (gr/mlcamp) were 10/250, 20/250 30/250. resul...

Molecular recognition is a central issue for nearly every biological mechanism. The analysis of molecular recognition to date has been conducted within the framework of classical chemical kinetics, in which the kinetic orders of a reaction have positive integer values. However, recent theoretical and experimental advances have shown that the assumptions inherent in this classical framework are ...

Here, we evaluate the electrochemical performance of sparsely studied natural crystals of molybdenite and graphite, which have increasingly been used for fabrication of next generation monolayer molybdenum disulphide and graphene energy storage devices. Heterogeneous electron transfer kinetics of several redox mediators, including Fe(CN)6(3-/4-), Ru(NH3)6(3+/2+) and IrCl6(2-/3-) are determined ...

Arsenic, one of the most toxic and dangerous elements in the environment affecting millions of people around the world, is associated with several diseases. In this pilot study, we investigated removal of arsenate from aqueous solutions using chitosan under the influences of initial arsenic ion concentrations, pH, contact time, and adsorbent dosages of chitosan. In order to assess the sorption ...
