41. A calorimetric and equilibrium investigation of the reaction {methyl ferulate(aq) + H2O(l) = methanol(aq) + ferulic acid(aq)}
Topic: Chemistry
Published: 1/3/2011
Authors: Robert Nathan Goldberg, Michael J Selig, Stephen R. Decker, Brian E Lang
Abstract: Microcalorimetry and high-performance liquid chromatography (HPLC) have been used to conduct a thermodynamic investigation of the reaction: {methyl ferulate(aq) + H2O(l) = methanol(aq) + ferulic acid(aq), as catlyzed by feruloyl esterase. Values of ...

42. A magnetic levitation technique for the simultaneous comparison of mass artifacts in air and vacuum.
Topic: Chemistry
Published: 4/1/2009
Authors: Patrick J Abbott, Zeina Jabbour Kubarych, Ruimin Liu, Edwin Ross Williams, Joe Chalfoun
Abstract: We describe a mass comparison system in which a test mass artifact in air can be directly compared to a standard mass artifact in vacuum using the same high precision comparator balance. The system uses a magnetic levitation technique to couple the ...

43. A primary pressure standard at 100 kPa
Topic: Chemistry
Published: 6/1/1999
Authors: James W Schmidt, Y Q Cen, Robert Gregory Driver, Walter J. Bowers Jr., J C. Houck, S A Tison, Charles D Ehrlich
Abstract: Primary pressure standards in the atmospheric pressure range are often established using mercury manometers. To a lesser extent controlled-clearance dead-weight testers in which one component (normally the piston) has been dimensionally measured hav ...

44. A rapid, low-cost preparation of monodisperse niosomes in a microfluidic platform
Topic: Chemistry
Published: 6/1/2010
Authors: Catherine T. Lo, Andreas Jahn, Wyatt N Vreeland, Laurie E Locascio
Abstract: Niosomes are synthetic membrane vesicles made of self-assembled non-ionic surfactants (i.e. amphiphilic organic compounds). They bear the same properties as liposomes, namely having an aqueous interior that is separated from the exterior aqueous env ...

45. A sensitive high resolution neutron imaging detector
Topic: Chemistry
Published: 11/11/2000
Authors: Y T Cheng, David F. R. Mildner

46. ADVANCES IN PORE STRUCTURE CHARACTERIZATION AND PERFORMANCE PREDICTION OF PERVIOUS CONCRETES
Topic: Chemistry
Published: 5/3/2010
Authors: Narayanan Neithalath, Dale P Bentz, Milani S Sumanasooriya
Abstract: Pervious concrete is receiving renewed interest as a sustainable construction material for parking lots, sidewalks, and low-traffic-volume roads. A key characteristic of this material is its coarse porosity, achieved by omitting the fine aggregates ...

47. ANN Model for HEMTs Constructed from Large-Signal Time-Domain Measurements
Topic: Chemistry
Published: 6/7/2002
Authors: Dominique Schreurs, Jeffrey A Jargon, Catherine A Remley, Donald C. DeGroot, Kuldip Gupta
Abstract: We develop a methodology to construct behavioral models for microwave devices from time-domain large-signal measurements. The behavioural model for the considered class of devices (microwave transistors) is defined by expressing the terminal current ...

48. Ab initio study of the mechanical and the transport properties of pure and contaminated silver nanowires
Topic: Chemistry
Published: Date unknown
Authors: Shmuel Barzilai, Francesca M Tavazza, Lyle E Levine
Abstract: The conductance and mechanical properties of pure and contaminated silver nanowires were studied using density functional theory (DFT) calculations. Several nanowires containing O2 on their surface were elongated along two different directions. All o ...
