Materials Research Innovations, 2009 AbstractStabilisation and microstructural examination of stabilised electroplating industrial sludge has been studied. Investigations were undertaken to formulate cementitous binder by judicious blending of fly ash, sludge and cement with five mix proportions. The major metallic contaminants were cadmium, chromium, copper, nickel and lead.

Polymer matrix composite tanks offer major advantages to the transport industry in terms of increased payload and corrosion resistance compared to conventional steel tanks. Chemical resistance and versatility can be enhanced through the addition of a thermoplastic liner. This paper presents the results of chemical conditioning, testing and analysis of

Abstract The atomic absorption spectrometric determinations of iron, calcium, and magnesium in the fluoboric-boric acids matrix are seriously interfered by the presence of silicon and aluminum. These interferences can be overcome by preparing the standard solutions of magnesium, calcium, and iron with silicon and aluminum concentrations matching ...

Detection of the spatial distribution and temporal evolution of an element in different chemical states is difficult in transmission electron microscopy. Here, taking the lithium element as an example, spatial and temporal distribution of different lithium-containing compounds could be revealed by using electron energy-loss spectroscopy (EELS) combined

Materials Science and Engineering: A, 1999 Abstract Uncoated and copper electroless coated fine NiTi superelastic particles have been incorporated into a liquid SnPbAg matrix. The wettability of the Cu coating by the molten alloy was determined with a wetting balance. The composite interfaces have been investigated by Auger electron spectroscopy (AES). Uncoated NiTi reacted with the matrix to

Matrix metalloproteinases (MMPs) play a critical role in physiological processes and pathological conditions such tumor invasion and metastasis. In recent years, a number of MMP inhibitors have been proposed, including the chemically modified tetracyclines (CMTs), which have been evaluated in preclinical cancer models showing promising results.
