We present PM-MetaFrame, a tool for automatic synthesis (i.e. prior to any enaction) of linear process models from speciications written as global constraints in linear time temporal logic. Key to the automatic synthesis is its level of abstraction: process model components are described logically by a taxonomic classiication, expressing semantic properties, and the ow of data is only considere...

We have introduced a selective synthesis of tertiary amines using alkyl halide and ammonium salts as the amine sources in water. This green process has outstanding superiorities, such as being eco-friendly, possessing ammonium salts, and using water as a green solvent in the absence of organic ligands or catalysts. It is worth mentioning that the presence of t-Butyl alcohol and potassi...

Systematic approaches for the invention of conceptual chemical process designs have been proposed and discussed for more than twenty-five years, and have now been developed to the point of industrial application. Process synthesis has also now become an integral part of many chemical engineering design curricula. CACHE has contributed to the promotion and advancement of conceptual design and pr...

niques in developing design programs provides formalisms for representing p r o b l e m s o l v i n g processes. In this article, the use of AI techniques in modeling design processes is elaborated with the presentation of three models that formalize the representation of design knowledge within a design program. For the purpose of establishing the relevance of the models presented here, a stru...

In this work, perlite was used as a low-cost source of Si and Al in the synthesis of sodalite zeolite using hydrothermal synthesis method. Cu2O nanoparticles were coated on a bed of sodalite zeolite and used as an adsorbent for removal of diazinon from aqueous solutions. To analyze the process, a significant variable .i.e. removal efficiency (%) of diazinon and three dependent parameters as the...

The nanoparticles of Ti and TiO2 have attracted extensive research interest because of their diverse applications in, for instance, catalysis, energy conversion, pigment and cosmetic manufacturing and biomedical engineering. Through this project, a one-step bulk synthesis method of electromagnetic levitational gas condensation (ELGC) was utilized for the synthesis of monodispersed and crystalli...

   In the present work, a fast, green and simple synthesis method for the production of silver nanoparticles (AgNPs) is introduced. Silver nanoparticles are currently among the most widely used man-made nano materials, present in a wide range of consumer products. Green chemistry is characterized by careful planning of chemical synthesis of silver nanoparticles to reduce adverse outcomes. S...
