Survey of Industrial,Agricultural, and Medical Applications of Radiometric Gauging and Process Control

Photon and particle radiations (gamma rays, x rays, brems-strahlung, electrons and other charged particles, and neutrons) from radioactive isotopes, x-ray tubes, and accelerators are now widely used in gauging, production control, and other monitoring and metrology devices where avoidance of mechanical contact is desirable. The general principles of radiation gauges, which rely on detection of radiation transmitted by the sample, or on detection of scattered or other secondary radiations produced in the sample, are discussed. Examples of such devices currently used or at least shown to be feasible in industrial, transportation, building, mining, agricultural, medical, and other metrology situations are presented, drawing from a total of 146 selected technical and review paper reference sources here cited.

Low-Temperature Properties of Silver

Pure silver is used extensively in the preparation of high-temperature superconductor wires, tapes, films, and other configurations in which the silver not only shields the superconducting material from the surrounding materials, but also provides a degree of flexibility and strain relief, as well as stabilization and low-resistance electrical contact. Silver is relatively expensive, but at this stage of superconductor development, its unique combination of properties seems to offer the only reasonable means of achieving usable lengths of conductor. In this role, the low-temperature physical (electrical, thermal, magnetic, optical) and mechanical properties of the silver all become important. Here we present a collection of properties data extracted from the cryogenic literature and, to the extent possible, selected for reliability.     

Preparation and adsorbing performance of calcium titanate with template method

In this paper, using furfural residue as a template, porous calcium titanate (FPCT) was prepared by a sol-gel method and characterized by XRD, SEM, and nitrogen adsorption method. The conditions of preparation were investigated. The adsorption capabilities of FPCT for heavy metal ions were studied, and the adsorption mechanism was investigated. The results show that the calcium titanate was porous, and material is composed of crystals in nanoparticle size with a small amount of calcium sulfate impurities, while the sulfuric acid in furfural residue is fixed as the calcium sulfate in the material. The adsorbed quantity is affected by the pH value of medium and time. When the pH value of medium is 5, and oscillating adsorption lasts for 30?min, the adsorbed quantities of Cd, Pb, Zn, Cu, and Ni are 118.04, 197.96, 64.98, 56.85, and 47.91?mg/g, respectively. The adsorption conforms to the Langmuir adsorption isothermal model and pseudo-second-order kinetic equation, and is a spontaneous endothermic process driven by entropy. After adsorption, adsorbents can be regenerated with 1?mol/L nitrate solution. It is used for eliminating Cd, Pb, Zn, Cu, and Ni in wastewater and the results are satisfactory.

In 1985, the CODATA Bulletin published a Report of its Task Group on Thermophysical Properties of Solids which analyzed available data on, and gave recommended values for, the heat capacity of Cu, Fe, W, and Al₂O₃, the thermal expansion of Cu, Si, W, and Al₂O₃, the electrical resistivity of Cu, Fe, Pt, and W, the thermal conductivity of Al, Cu, Fe, and W, and the absolute thermopower of Pb, Cu, Pt, and W.
