Preparation of porosity-controlled calcium carbonate by thermal decomposition of volume content-variable calcium carboxylate derivatives.
We demonstrate a novel approach for synthesizing porosity-controlled calcium carbonate by one-step thermal decomposition of various calcium carboxylate derivatives as well as their mixtures with different molar ratios. By varying the volume content of calcium in the calcium compounds or mixtures, the resulting porous calcium carbonate exhibits distinct porosity and structures that are very prom...
متن کاملCharacterization and analysis of waxes by differential thermal analysis.
The characterization of waxes by differential thermal analysis is described. An endothermic peak at 475-480 degrees is characteristic of microcrystalline and polyethylene waxes, and measurement of its area provides a method for the estimation of these waxes in mixtures.
متن کاملThe Variable-Atmosphere Wave Tank
A facility was constructed for the study of waterentry, water-exit, and underwater trajectory behavior of small momentum-propelled missiles for varied trajectory launching angles, missile accelerations and velocities, wave fields and condi tions of cavitation. A unique feature is the electromagnetic missile propulsion system. The facility is made principally of non-magnetic and electrically non...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولOn the quantification of atmospheric carbonate carbon by thermal/optical analysis protocols
The objective of this work was to study the possibility of identifying and quantifying atmospheric carbonate carbon (CC) by thermal-optical analysis. Three different temperature protocols, two modified NIOSH-like protocols (RT-QUARTZ-840 and RT-QUARTZ-700), and the EUSAAR 2 protocol were tested on filter samples containing known amounts of CC with the semi-continuous Sunset analyzer. Carbonate ...
