Evaluated Kinetic and Photochemical Data for Atmospheric Chemistry...

By: D.L. Baulch

Technical Reference Publication

Preface: This paper is the first supplement to the original set of critically evaluated kinetic and photochemical rate parameters for atmospheric chemistry, published by the CODATA Task Group on Chemical Kinetics in 1980 [l]. At the present rate of publication of experimental laboratory data on the rates of elementary atmospheric reactions, we estimate that Supplements to the Evaluation are required at approximately two-year intervals.

Toward Next-Generation Construction Machines

By: James Sacra Albus

Technical Reference Publication

Abstract: Construction equipment is typically massive and operated manually with minimal use of sensors or computers for measurement or control. Research in the Intelligent Systems and Structures Divisions at the National Institute of Standards and Technology has explored innovative ways to use sensors, computers, and light-weight, tensioned, cable machines for heavy manufacturing and construction tasks such as lift and position of heavy loads and manipulation of tools a...

Thermodynamic Functions and Properties of Mgo at High Compression

By: Orson L. Anderson

Technical Reference Publication

Introduction: The principal objective of this work is to evaluate and publish the data for all the thermodynamic functions of an important mineral, MgO or periclase, with a temperature range of 300 to 2000 K, and with a compression range. It is well known that the computations of thermodynamic functions (entropy, for example) require knowledge of the thermal expansibility a and compressibility K as well as the specific heat. The pressure (or volume) and temperature varia...

Cross Sections and Related Data for Electron Collisions with Hydrogen

By: H. Tawara

Technical Reference Publication

Introduction: A number of experimental and theoretical investigations of collision processes involving hydrogen molecules and molecular ions in electron impact have been and are still being performed extensively because they are of the most fundamental importance in electron-molecule collisions. Indeed, understanding of electron-molecule collision processes is requisite in many applications such as chemistry, astrophysics, astrochemistry, plasma fusion research, and plas...

Cross Sections and Swarm Coefficients for Nitrogen Ions and Neutra...

By: A.V. Phelps

Technical Reference Publication

Introduction: This paper presents graphical and tabulated data and the associated bibliography for cross sections for elastic, excitation, and ionization collisions of N', N:, N, and N, in N2 and for Ar+, Ar?, and Ar in Ar for laboratory energies from 0.1 eV to 10 keV. Ion transport and reaction coefficients calculated from these cross sections are compared with available experimental data and are tabulated. Thc rcsults presented here are a continuation of a similar comp...
