Effect of C2H2/H2 Gas Mixture Ratio in Direct Low-Temperature Vacuum Carburization
Metals, 2018 The effect of the acetylene and hydrogen gases mixture ratios in direct low-temperature vacuum carburization was investigated. The gas ratio is an important parameter for producing free radicals in carburization.

Experimental determination of rotational temperatures and concentrations of OH in flames from emission spectra [PDF]
, 1955 In order to illustrate the use of two‐path experiments for correcting for self‐absorption, experimental studies to determine the rotational "temperatures" and concentrations of OH in flames burning at atmospheric pressure have been carried out.

Acetylene terminated aspartimides and resins therefrom [PDF]
, 1989 Acetylene terminated aspartimides are prepared using two methods. In the first, an amino-substituted aromatic acetylene is reacted with an aromatic bismaleimide in a solvent of glacial acetic acid and/or m-cresol.

Controlled Synthesis of Carbon-Encapsulated Copper Nanostructures by Using Smectite Clays as Nanotemplates [PDF]
, 2012 Rhomboidal and spherical metallic-copper nanostructures were encapsulated within well-formed graphitic shells by using a simple chemical method that involved the catalytic decomposition of acetylene over a copper catalyst that was supported on different ...
