In this work a novel ion imprinted polymer (IIP) based on N-(pyridin-2-ylmethyl)ethenamine (V-Pic) was coated on Fe3O4 nano-particles and characterized by thermal gravimetric and differential thermal analysis (TG/DTA), IR spectroscopy, Scanning electron microscopy (SEM) and also elemental analysis. The application of this novel magnetic sorbent was investigated in rapid extraction, preconcentra...

Ideally, an artificial kidney should simulate the normal kidney in providing continuous metabolic control, removal of toxins, and unrestricted patient freedom. Of the dialysis procedures available, continuous ambulatory peritoneal dialysis (CAPD) comes the closest to this ideal but provides inadequate dialysis and fails to remove protein-bound toxins. A continuous, wearable, peritoneal-based ar...

A novel extraction approach was developed based on rotating-disk sorptive extraction (RDSE). In this approach the rotating-disk extraction device consists of a Teflon disk, with a cavity that is loaded with a commercial sorbent phase selected according to the polarity of the analyte. To avoid leakage of the sorbent, the cavity is covered with a fiberglass filter and sealed with a Teflon ring. T...

Executive Summary Western Research Institute (WRI) and its cosponsor Novinda Corporation (the Company was originally known as Amended Silicates, Inc.) proposed the development, characterization and testing of sorbents based on clay deposits abundant in Wyoming for the in-flight capture of mercury in pulverized coal derived flue gasses. As a part of the State of Wyoming’s Clean Coal Technologies...

The ability to collect uranium from seawater offers the potential for a nearly limitless fuel supply for nuclear energy. We evaluated the use of functionalized nanostructured sorbents for the collection and recovery of uranium from seawater. Extraction of trace minerals from seawater and brines is challenging due to the high ionic strength of seawater, low mineral concentrations, and fouling of...

Plant volatiles (PVs) mediate manifold interactions between plants and their biotic and abiotic environments (Dicke and Baldwin, 2010; Holopainen and Gershenzon, 2010). An understanding of the physiological and ecological functions of PVs must therefore be based on measurements of PV emissions under natural conditions. Yet sampling PVs in natural environments is difficult, limited by the need t...

A CO2 solid sorbent based on polyethyleneimine 10k (PEI-10k) impregnated into mesoporous silica (MPS) foam was synthesized and utilized to capture CO2 at temperatures ranged from 65 ̊C to 95 ̊C. The calculated nitrogen and carbon contents in the bulk of the PEI-10k/MPS sorbent were similar to the XPS results measured on the surface of the foam, suggesting that the PEI was homogeneously distribute...

a novel, simple, sensitive and effective method has been developed for preconcentration of hg(ii) on nano-fe3o4-dop-ed solid-phase extraction adsorbent. in this paper, dioctyl phthalate (dop) was used to encapsulate nano-fe3o4 and produce a nano-fe3o4-dop sorbent based new sorbent was prepared. this was treated with ethylenediamine (ed) in another solvent-free procedure for the formation of a n...

Thermal-driven refrigeration systems have attracted increasing research and development interest in recent years. These systems do not cause ozone depletion and can reduce demand on electricity. The main objective of this work is to perform theoretical analyses of a thermal-driven refrigeration system using a new sorbent-sorptive pair as the working pair. The active component of sorbent is sodi...
