UNLABELLED A weekly monitoring campaign of volatile organic compounds (VOC), with single sampling of 24 h, was carried out in non-residential indoor environments such as libraries, pharmacies, offices, gymnasiums, etc., in order to evaluate the VOC concentrations to which people are exposed. Moreover, an outdoor sample was coupled to each indoor site to(More)
A multivariate statistical method has been applied to apportion the atmospheric pollutant concentrations measured by automatic gas analyzers placed on a mobile laboratory for air quality monitoring in Taranto (Italy). In particular, Principal Component Analysis (PCA) followed by Absolute Principal Component Scores (APCS) technique was performed to identify(More)
Combining kinetic Monte Carlo and molecular static simulations, we follow at the atomic scale the growth of Co nanoislands on Cu͑111͒ surface over a wide range of surface temperatures ͑130– 300 K͒. Atomistic processes responsible for the interlayer mass transport of Co atoms and the formation of 2 ML high nanois-lands at temperatures Ͼ200 K are revealed.(More)
As a token of my deep appreciation for their professionalism and dedication to the ideals of our magazine, I hereby acknowledge with the list below the many reviewers that have reviewed tirelessly papers for IEEE Network during the past year. Their behind the scenes work provides the strong foundation upon which the quality papers that you read in our(More)
The determination of polycyclic aromatic hydrocarbons (PAHs) contained in samples of particulate matter (PM), collected with low volume pumps, were carried out with an high sensitivity method that comes from several revisions of a previous method. The present work describes how, by using programmable temperature vaporization (PTV) and a mass selective(More)
Cu, Ni, Zn, Co, Fe+2, Mn, Cd, Fe+3 and Pb are easily separated and detected in isocratic mode by ion chromatography with post-column derivatization using a bifunctional ion-exchange column and an eluent formed by oxalic acid (28 mM) and sodium nitrate (250 mM). The separation is optimised by using a suggested sample solution containing a given concentration(More)
Nuisance caused by odors is one of the most important problems for waste management plants. To control an odor nuisance, it must first be quantified. The analytical difficulties in odor measurements are related to the high number of volatile components (belonging to several chemical classes), above all when the concentration is lower than the detection(More)
In this paper, improvements obtained by using focused microwaves for extraction, in the analysis of polycyclic aromatic hydrocarbons (PAHs) adsorbed on particulate matter, are discussed. The method was tested on the following PAHs, which are considered to be among the most harmful with regard to carcinogenicity: benzo[a]anthracene, benzo[b]fluoranthene,(More)
The high electron mobility spin transistor comprises a 1D or 2D electron gas, obtained from III-V semiconductor heterostructure, with ferromagnetic source and drain contacts. The latter act respectively as a polarizer and as an analyzer for the spin of the electrons, and the gate potential is used to control the spin precession in the channel. After(More)
