Recent studies have shown that the mullitization of diphasic aluminosilicate matrices comprising transitional alumina and amorphous silica occurs via a nucleation and growth process. Nucleation is preceded by a temperature-dependent incubation period. Following this incubation period, rapid nucleation of mullite occurs, producing about 1.8 X 10" nuclei/cm3, which remains constant throughout the...

Room temperature (RT) synthesis of the ternary cesium lead bromide CsPbBr3 quantum dots with oleic acid and oleylamine ligands was developed by Zeng coworkers in 2016. In their works, supersaturated recrystallization (SR) adopted as a processing method without requiring inert gas high-temperature injection. However, ligand for haloplumbate is known to be relatively unstable. Hence, this work, w...

binary decision diagram (bdd) is a data structure proved to be compact in representation and efficient in manipulation of boolean formulas. using binary decision diagram in network reliability analysis has already been investigated by some researchers. in this paper we show how an exact algorithm for network reliability can be improved and implemented efficiently by using cudd - colorado univer...

because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...

The increasing importance of aerosols in industry, in the treatment of pulmonary conditions and more recently in the diagnosis and experimental study of bronchial asthma has intensified the need for a method permitting measurement of the amount of aerosol retained in the human lung. This problem has been approached in various ways. Landahl and Hermann (1) measured the difference in concentratio...

Elemental sulfur exists as a variety of forms in natural systems, from dissolved forms (noted as S8 (aq.)) to bulk elemental sulfur most stable as α-S8 (bulk) (but existing in at least 180 different allotropes and polymorphs). Elemental sulfur can form via a number of biotic and abiotic processes, many of which begin with S-S bonding of practically unlimited length, forming chains and rings of ...
