Structure of 2-{2-[3-methyl-3-(2,4,6-trimethylphenyl) cyclobutyl]-2-oxoethyl}isoindole-1,3-dione
(Springer/Plenum Publishers, 2004)
2-{2-[3-Methyl- 3-(2,4,6-trimethylphenyl) cyclobutyl]-2-oxoethyl} isoindole-1,3-dione (C-24 H25NO3) was synthesized, and its crystal structure was determined by X-ray crystallographic techniques. The compound crystallizes ...
Application of the H-N method to the critical slab problem for reflecting boundary conditions
(Pergamon-Elsevier Science Ltd, 2004)
The recently developed H-N method is used to solve the critical slab problem for a slab which is surrounded by a reflector. In the special case: for R = 0 (the reflection coefficient) the problem reduces to the one under ...
Investigation of the (n, 2n) reaction cross sections of some neighbouring nuclei with and without deformation
(Indian Assoc Cultivation Science, 2004)
The (n, 2n) reaction cross section calculations for some neighbouring target nuclei either with deformation or without deformation have been made for an incident energy range of 8 - 24 MeV. In these calculations, the ...
Prism coupling technique investigation of elasto-optical properties of thin polymer films
(Amer Inst Physics, 2004)
The use of thin polymer films in optical planar integrated optical circuits is rapidly increasing. Much interest, therefore, has been devoted to characterizing the optical and mechanical properties of thin polymer films. ...
Vickers microhardness studies of Fe-Mn binary alloys
(Elsevier Science Bv, 2004)
The room temperature microhardness of Fe-Mn binary alloys with different compositions was measured using a Vickers microhardness tester in the applied load ranging from 0.245 to 4.9 N. A significant indentation size effect ...
