Guanidine and its derivatives have wide applications in various industries and energetic materials. Because of these wide applications, various researches are concentrated on the synthesis of guanidine and its derivatives. This review article has introduced synthesis methods of guanidine and its derivatives. Guanidine synthesis routes like addition of ammonium salts to cyanoguanidine or cyanam...
C. W. Bowen and G. M. Bodner “Problem-Solving Processes Used by Graduate Students While Solving Tasks in Organic Synthesis,” International Journal of Science Education, vol. 13, no. 2, pp. 143-158, 1991. Organic synthesis is the branch of chemistry that deals with the step-by-step conversion of relatively simple starting materials into larger, more complicated, target molecules. Synthesis probl...
The recent developments and trends in combustion science towards the synthesis of nanomaterials are discussed. Different modifications made to conventional combustion approaches for preparation of nanomaterials are critically analyzed. Special attention is paid to various applications of combustion synthesized nanosized products. 2008 Elsevier Ltd. All rights reserved.

A method for accelerating the discovery of ionic luminophores using combinatorial techniques is reported. The photophysical properties of the resulting transition-metal-based chromophores were compared against a series of analogous, traditionally prepared species. The strong overlap between these two sets confirms the identity of the parallel synthesis products and supports the truthfulness of ...
Identifying optimal conditions for chemical and material synthesis as well as optimizing the properties of the products is often much easier than simple reasoning would predict. The potential search space is infinite in principle and enormous in practice, yet optimal molecules, materials, and synthesis conditions for many objectives can often be found by performing a reasonable number of distin...
this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
