Collecting chemical data for site characterization and remediation at former manufactured gas plant (MGP) sites can be time consuming and costly, with sufficient data acquired at only a few sites. In response, EPRI has developed chemical analysis methods for utility use in generating data quickly and cost-effectively. This report presents results from a laboratory demonstration of sample prepar...

Electrochemical immunosensors have emerged as a highly sensitive and rapid technique for chemical contaminants detection in environmental monitoring, food safety and quality control. This review concentrates on recent advances made in detection and quantification of chemical contaminants such as pesticides and antibiotics residues with electrochemical immunosensors. In this paper, the preparati...

Biocatalysis has proven to be a useful supplementary technology for the chemical industry, allowing in some cases reactions which are not easily conducted by classical organic chemistry or in other cases allowing reactions which can replace several chemical steps. Highly chemo-, regioand stereoselective bioconversions can simplify manufacturing processes to make them even more economically attr...

Preparation of silver immobilized TiO2-Hectorite and its application in phenol photooxidation and Eschericia coli bacteria desinfection has been conducted. Material was obtained by two steps of synthesis: preparation of TiO2-Hectorite and silver immobilization into TiO2-Hectorite. Physico-chemical characterization to the prepared material compared to raw hectorite was conducted by X-ray Diffrac...

Mimicking Nature, supramolecular chemistry represents the chemistry beyond the molecule, in view that intermolecular interactions constitute the driving force for the preparation of molecular and supramolecular assemblies, using the chemical information contained in molecular building blocks. Upon molecular recognition between discrete units, chemical processes such as self-assembly and self-or...

A simple and green chemical procedure was reported for the synthesis of dihydropyrimidinones from various aldehydes, ethyl acetoacetate and urea or thiourea using  holmium chloride as catalyst. The reactions were performed under solvent free conditions with ultrasound irradiation as the energy source. The advantages of this protocol include the excellent yield, operational simplicity, short tim...

Two preparation methods (wet saturation impregnation with vanadyl acetylacetonate and ball-milling of γ-Al2O3 with crystalline V2O5) were applied to produce two sets of VOx/γ-Al2O3 catalysts with increasing vanadium loadings. Materials from both sets were characterized by XRD, SEM, Raman, TPR and UV/Vis-DRS to elucidate the influence of the preparation method on the morphology of VOx species an...

We present a tutorial review of our quantum state resolved experiments designed to study gas-surface reaction dynamics. The combination of a molecular beam, state specific reactant preparation by infrared laser pumping, and ultrahigh vacuum surface analysis techniques make it possible to study chemical reactivity at the gas-surface interface in unprecedented detail. We describe the experimental...

During the last decade the use of ω-transaminases has been identified as a very powerful method for the preparation of optically pure amines from the corresponding ketones. Their immense potential for the preparation of chiral amines, together with their ease of use in combination with existing biocatalytic methods, have made these biocatalysts a competitor to any chemical methodology for (asym...
