Roentgen's First Public Lecture, Fathi Habashi

Fathi Habashi

The Birmingham artist Robert Alan Thom (1915-1979) painted a picture in 1966 showing Wilhelm Conard Roentgen at his first public demonstration of the newly discovered X-rays in the evening of January 23, 1896. The lecture took place at the Physics Department Auditorium of the University of Würzburg in Germany where Roentgen was the rector. The painting shows Albert von Kölliker, professor of anatomy at the University putting his hand on a photographic plate to make an X-ray picture. The painting is published in an interesting book entitled Great Moments in Medicine by Parke, Davis & Company, Northwood Institute Press, Detroit …


Hitos En La Historia De La Metalurgia, Fathi Habashi Jun 2001

Hitos En La Historia De La Metalurgia, Fathi Habashi

Fathi Habashi

Up to the Middle Ages, seven metals were only known and used by man. These were gold, silver, copper, iron, lead, tin, and mercury. During the Middle Ages the metalloids arsenic, antimony, and bismuth were isolated as well as zinc that was imported from the East. In the Eighteenth century mineral specimens were continuously supplied and analyzed which resulted in the discovery of about a dozen new metals. With the discovery of electric current at the beginning of the nineteenth century the alkali metals were isolated and these were responsible for the isolation of new metals that were not possible …


History Of Rare Earths On Postage Stamps, Fathi Habashi Mar 2001

History Of Rare Earths On Postage Stamps, Fathi Habashi

Fathi Habashi

Postage stamps are important means of communication and many countries have recorded important events, honored worthy individuals, and described interesting facts through this medium. Many historical facts, sometimes obscure, can be found on stamps; some of these may not be easily located in a history or a science book. Stamps have artistic value, they are created by artists. Mining and Metallurgy on Postage Stamps is intended to give a historical background to mining and metallurgy by presenting about 900 enlarged reproductions of colored stamps from different countries. Explanations are given in simple language to bring these topics to young people, …


Chemisorption Of Organic Dyes On Chryostile Asbestos And The Toxicity Issue, Fathi Habashi Jan 2001

Chemisorption Of Organic Dyes On Chryostile Asbestos And The Toxicity Issue, Fathi Habashi

Fathi Habashi

Asbestos, an extremely useful natural resource, has been studied extensively mineralogically and for industrial application. Its extraction from ores has been greatly improved with respect to safety in the work place. In spite of that, there is a decisive effort in many countries to ban its use on the grounds that it is a toxic substance. This action resulting in drastic decrease in production and the possibility of destroying the industry. The chelation of asbestos with organic dyes seems to be a promising way to abate its toxicity. Dyeing can be done when the fibers are slurred in water at …

Hidrometalurjide Çöktürme. Precipitation In Hydrometallurgy, Fathi Habashi Aug 1995

Hidrometalurjide Çöktürme. Precipitation In Hydrometallurgy, Fathi Habashi

Fathi Habashi

Precipitation of inorganic compounds or metals from aqueous solutions can either be physical (crystallization) or chemical in nature. Chemical processes are varied: they may be due to hydrolytic action, due to to ionic interaction, or due to reduction, i.e., transfer of electrons. Transfer of electrons in reduction processes may take place homogeneously or heterogeneously. In the first case it may be ionic or non-ionic in nature. Heterogeneous processes may be electrochemical of electrolytic. Examples of interest to hydrometallurgy are given. Translated into Turkish by Prof. Murat Erdemoglu, Inönü Üniversitesi, Malatya, from Proceedings of XVIII International Mineral Processing Congress, Sydney, Australia …

One Hundred Years Bayer Process For Alumina Production [In Arabic], Fathi Habashi Feb 1988

One Hundred Years Bayer Process For Alumina Production [In Arabic], Fathi Habashi

Fathi Habashi

Karl Josef Bayer (1847-1904), an Austrian citizen, went to study for a short time under Remingius Fresenius in Wiesbaden, then under Robert Bunsen in Heidelberg from 1868 to 1871. After a short period of independent work in Brno in Moravia he left to Russia to work at the Tentelev Chemical Plant in Saint Petersburg then at Yelbuga. It was there that he invented his process for the production of pure alumina from bauxite. In 1894 he returned to Austria but died suddenly at the age of 57.

Friedrich August Henglein, Fathi Habashi

Fathi Habashi

Friedrich August Henglein (1893-1968) while working in the chemical industry in Germany performed in 1926 the first experiments for pressure leaching of zinc sulfide to form zinc sulfate solution. This was in connection of removing hydrogen sulfide from coke oven gas by absorption in zinc sulfate solution. The ZnS precipitated can then be transformed into zinc sulfate for recycle.
