Raman and infrared spectroscopy provide complementary information about the nature of the surface metal oxide species present in supported metal oxide catalysts. This paper reviews the type of fundamental information that is typically obtained in Raman and IR characterization studies of supported metal oxide catalysts. The molecular structures of the surface metal oxide species are reflected in...

Due to Technological advancement cathode-ray tubes (CRTs) from computer monitors and TV sets are being replaced continuously by thinner and lightweight versions like Liquid Crystal Display (LCD) or Plasma screen monitors. As regular discarding e-waste from CRTs are continuously increasing day by day and in UK alone it is projected to reach around 100,000 tonnes/year. CRT composition consists of...

metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 m...

estuaries are well known for their potential in removing metal from fresh water to provide micro-nutrients to aquatic life. in the present investigation, we have tried to bring out the metal removal potential of estuaries during accidental spills. for this purpose artificial river water containing high concentration of mn, cu, zn, ni and pb were mixed with sea water at different salinity regime...

background: the present study investigated the impact of land use on health risks (cancerous and non-cancerous) of heavy metals in soil along the hemmat highway of tehran, iran. materials and methods: a total of 28 soil samples were collected in august 2014 from the roadside soil of the hemmat highway. the collected samples were air-dried and digested, and then, analyzed for heavy metals using ...

In the last decade, the market for non-volatile computer storage has experienced rapid growth. However, as the device size scales down, currently used NOR and NAND technology is facing limitations from tunnel oxide and electrostatic interactions between cells (Lacaita & Wouters, 2008). To solve the scaling problems, in the last fifteen years, a number of alternative Flash memory technologies ha...

VAN.Fans of heavy metal music have created their own subculture which. Arnetts 1996 book Metalheads: Heavy Metal Music and Adolescent Alienation argues that. Especially in adolescence and young adulthood Rentfrow Gosling, 2006. Rebellious music rock, alternative, and heavy metal was posi. Culture of alienation among heavy metal fans, which, in turn, was.Attitudes and characteristics of adolesce...

X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...
