From:Polymer Engineering and Science (Vol. 53, Issue 5) Peer-ReviewedPoly (acrylonitrile-co-methyl acrylate) copolymer designated as PANMA was used for making pervaporation membrane. This membrane was used for separation of acetic acid-water mixtures over the concentration range of...
-
From:Environmental Health Perspectives (Vol. 130, Issue 4) Peer-ReviewedDistinguishing chemical mixtures in terms of the similarity vs. dissimilarity of their components' mechanisms or modes of action (MOAs) is perceived as a key issue in mixture risk assessment. However, the well-designed...

From:Polymer Engineering and Science (Vol. 49, Issue 5) Peer-ReviewedTwo poly(butylene terephthalate) (PBT)-rich compositions of PBT/poly(ethylene terephthalate) (PET) blends (5/1 and 2/1) were mixed with up to 30 wt% of a maleinized poly(ethylene-octene) copolymer (mPEO). The blends...
-
From:Journal of ThermodynamicsPeer-ReviewedVapor-liquid equilibrium (VLE) data for the strongly associated ternary system methanol + water + ethanoic acid and the three constituent binary systems have been determined by the total...
-
From:Hazardous Waste Consultant (Vol. 21, Issue 6) Peer-ReviewedIn the continuation of a long and complicated saga, the U.S. Court of Appeals for the District of Columbia has determined that EPA did not exceed its statutory authority under RCRA when it re-issued the mixture and...
-
From:Canadian Journal of Physics (Vol. 96, Issue 5) Peer-ReviewedIn this paper, the current-voltage graphs of discharge in the chamber of capacitive coupled radio frequency (CCRF) at low pressure were presented for Langmuir probe. The Langmuir probe measurements for estimating the...

From:Journal of Analytical Chemistry (Vol. 73, Issue 2) Peer-ReviewedA review of methods for the preparation of standard gas mixtures (SGMs) with the known concentrations of organic and inorganic gases and vapors is presented. The classification of methods is proposed and their...
-
From:Journal of Research of the National Institute of Standards and Technology (Vol. 105, Issue 6) Peer-ReviewedPersonnel from the NIST Center for Neutron Research (NCNR) recently participated in an international round-robin on the use of diffraction techniques for the quantification of phase abundance in multiphase mixtures....
-
From:Science and Children (Vol. 45, Issue 5) Peer-ReviewedChildren learn about properties of materials as they walk through a fabric store, help in the kitchen, or dig in the garden. Directed explorations in the classroom build on these early experiences and are part of the...
-
From:Canadian Journal of Microbiology (Vol. 55, Issue 4) Peer-ReviewedThe characterization of surfactin-producing Bacillus subtilis isolates collected from different ecological zones of Iran is presented. Characterization was performed using blood agar, PCR, drop-collapse, and...

From:Environmental Health Perspectives (Vol. 129, Issue 9) Peer-Reviewed
A Framework for Cumulative Risk Assessment: Exploring the Carcinogenic Effects of Chemical Mixtures.
Humans are commonly exposed to mixtures of chemicals in their environments, rather than to one compound at a time. Accordingly, researchers have long been interested in the complex task of studying how mixtures affect... -
From:Construction and Building Materials (Vol. 148) Peer-ReviewedABSTRACT Wheel tracking testing on AC-20 limestone asphalt mixtures was carried out to determine the effect of multi-stress loading on rutting development. Rutting rates increased with the application of higher...
-
From:Construction and Building Materials (Vol. 159) Peer-ReviewedABSTRACT Micro or nano zinc oxide (ZnO), as a modifier, can significantly improve some properties of asphalt and asphalt mixture, but the effect of ZnO particle size is still unclear. In this paper, three different...
-
From:Polymer Engineering and Science (Vol. 39, Issue 3) Peer-ReviewedA series of polyurethane + polyacrylate latexes has been synthesized by putting different quantities of polyacrylate dispersion into an acetone solution of an anionic polyurethane prepolymer with terminal isocyanate...
-
From:Science Scope (Vol. 40, Issue 8) Peer-ReviewedStudents may hold onto the misconception that all liquids naturally combine when put into the same container (e.g., adding food coloring to water and adding chocolate syrup to milk). This activity aims to show students...
