Membrane Distillation (MD) is a membrane-based operation able to give 100% theoretical ions rejection and to efficiently work with high concentrated brines. Both features make MD of interest for the purification of wastewater, the production of ultra-pure water and the concentration of brines produced in desalination. MD, also integrated with other membrane operations, can be a valuable way to ...

BACKGROUND The use of a boiling mixture of hydriodic acid, hypophosphorous acid, and hydrochloric acid to reduce any variety of sulfur compounds has been in use in various applications since the first appearance of this method in the literature in the 1920's. In the realm of sulfur geochemistry, this method remains a useful, but under-utilized technique. Presented here is a detailed description...

We present results of the growth of thin films of crystalline H2O2 and H2O2*2H2O (dihydrate) in ultrahigh vacuum by distilling an aqueous solution of hydrogen peroxide. We traced the process using infrared reflectance spectroscopy, mass loss on a quartz crystal microbalance, and in a few cases ultraviolet-visible reflectance. We find that the different crystalline phases-water, dihydrate, and h...

This study aims to determine the effect of soaking time in distilled and non-distilled liquid smoke kusambi wood (Schleicera oleosa) on quality smoked skipjack fillets. used an experimental method designed with a completely randomized design (CRD) two factor treatments. The first was four levels, namely 10, 20, 30 40 min. second treatment type from (without distillation). variables observed thi...

A dynamic model for the simulation of the batch operation of a multicomponent packed distillation column is developed. The accuracy of simulation code is verified by using two types of mixtures (cyclohexane-n-heptane-toluene and ethanol–water) theoretically and experimentally. An optimum internal reflux ratio profile is searched to maximize the distillate amount of a specified concentration for...

We experimentally demonstrate the two-step distillation of entanglement. The output of a first distillation stage underwent a second distillation step and was made available for subsequent steps. Our experiment displays the realization of the building blocks required for an entanglement distillation scheme that can fully overcome decoherence.

Cache hierarchies play a very important role in bridging the speed gap between processors and memory. As this gap increases, it becomes increasingly important to intelligently design and manage a cache system. The performance of current caches is reduced because more than half of the data that is brought into the cache is never referenced, resulting in very low utilization. We propose line dist...

The interpretation of the isotopic composition of Andes tropical mountain glaciers is reconsidered using a simple Rayleigh distillation model. It is shown that Andes snowline depression and Huascaran ice core δO are consistent with a 3C drop in sea surface temperature during the Last Glacial Maximum, accompanied by an increase from 40% at present to 60% during the LGM in the annual mean proport...

No subsequent observers, however, have been able to obtain, by the process employed by Smith, any body which fully answers to the description of Smith's ' Cannabin. ' In 1S57 Personnel) resolved the volatile oil, obtained by distillation of ^e plant, with water, into Cannabene (C18 H?0) a light hydrocarbon, and a Solid crystal...

Although thermal desalination technology provides potable water in arid regions (e.g., Israel and the Gulf), its relatively high cost has limited application to less arid regions with large populations (e.g., California). Energy-intensive distillation is currently being replaced with less costly pressure- and electrically driven membrane-based processes. Reverse osmosis (RO) is a preferred memb...
