A RAPID ESTIMATION OF METAL CONTENTS IN WASTEWATER TREATMENT FOR CONDUCTIVITY MEASUREMENTS
(Sociedad Chilena de Química, 2005)
Theory of electrical characteristics for metal-oxide-insulator Schottky barrier and metal-insulator-metal structures
(1990-12-01)
The metal-insulator or metal-amorphous semiconductor blocking contact is still not well understood. Here, the intimate metal-insulator and metal-oxide-insulator contact are discussed. Further, the steady-state characteristics ...
Metal hyperaccumulation in plants: Biodiversity prospecting for phytoremediation technology
(Pontificia Universidad Católica de Valparaíso, 2003)
Interaction between humic substances and metallic ions: A selectivity study of humic substances and their possible therapeutic application
(2007-09-06)
The complexation capacity of humic substances extracted from peat samples taken from the Mogi River in Ribeirao Preto, SP, Brazil, was determined using metal ions (Al(III), Pb(II), Cr(VI) and Cd(II)), yielding the following ...
Metal fractionation in sludge from sewage UASB treatment
(2017-05-15)
This study evaluates the trace metal composition and fractionation in sludge samples from anaerobic sewage treatment plants from six cities in Brazil. Ten metals were evaluated: Ni, Mn, Se, Co, Fe, Zn, K, Cu, Pb and Cr. ...
Advances in metal-assisted non-electrophilic fluoroalkylation reactions of organic compounds
(Elsevier, 2015-02)
Metal-assisted trifluoromethylation and perfluoroalkylation reactions are probably one of the first approaches employed to achieve fluoroalkyl-group substitutions of organic substrates through the use of metals such as ...
Metal-ion effects on the polarization of metal-bound water and infrared vibrational modes of the coordinated metal center of mycobacterium tuberculosis pyrazinamidase via quantum mechanical calculations
(American Chemical Society, 2014)
Mycobacterium tuberculosis pyrazinamidase (PZAse) is a key enzyme to activate the pro-drug pyrazinamide (PZA). PZAse is a metalloenzyme that coordinates in vitro different divalent metal cofactors in the metal coordination ...
