Structures and melting of Ag-N (N = 7, 12-14) clusters
(Iop Publishing Ltd, 2005)
We have studied the most stable structures of Ag-N (N = 7, 12, 13, 14) clusters and investigated their binding energies and melting behaviours using molecular dynamics and thermal quenching methods based on the Voter-Chen ...
Effect of medications for root canal treatment on bonding to root canal dentin
(Lippincott Williams & Wilkins, 2004)
Use of resin-based restorative materials recently has become widely accepted for treatment of endodontically treated teeth. However, some solutions routinely used during endodontic treatment procedures may have an effect ...
Superconducting and Vickers hardness properties of ZnO-added YBCO polycrystalline superconductors
(Wiley-V C H Verlag Gmbh, 2004)
The effects of ZnO addition on the microstructure and mechanical properties of the YBCO have been investigated through XRD, SEM, EDX, ac susceptibility measurements and the standard Vickers micro-hardness testing method. ...
The study of the (n,2n) reaction cross-sections for neighbor deformed nuclei in the region of rare-earth elements
(Slovak Acad Sciences Inst Physics, 2004)
The (n,2n) reaction cross-section calculations for some neighbor deformed target nuclei have been made in the region of rare-earth elements between 8 and 24 MeV incident energy. In the calculations, the geometry dependent ...
4-[(4-chlorobenzylidene)amino]phenol
(Int Union Crystallography, 2004)
In the molecular structure of the title Schiff base, C13H10ClNO, the chlorophenyl ring and formimidoyl moiety are almost coplanar, and the dihedral angle between the planes of the phenol and chlorophenyl ring is 34.57 ...
The effect of nitrogen atom on double bond pyramidalization
(Springer/Plenum Publishers, 2004)
The title compound 6-phenyl-4,6,8-triazatetracyclo[9.2.1.0(2,10).0(4,8)] tetradec-2(10)-ene-5,7-dione ( 6) has been synthesized by the addition of 4-phenyl-1,2,4-triazole-3,5-dione (PTAD) to 2,3-dimethylenebicyclo[2.2.1] ...
Morphological changes in diseased cementum layers: A scanning electron microscopy study
(Springer, 2004)
The aim or this study was to compare the morphological changes that occurred in root cementum layers due to periodontal disease by using scanning electron microscopy (SEM). Ninety-two periodontally hopeless teeth extracted ...
Dispersion-strengthening effect of Cu-based Mn, Al, and Zn rich alloys
(Elsevier Science Sa, 2004)
In this systematic study, dispersion-strengthening effect of the Cu-25.91Mn (wt.%), Cu-26.62Mn-8.99Al (wt.%), Cu-22.17Mn-12.32Zn (wt.%) ingot alloys have been investigated. Samples were homogenized at a high fixed temperature ...
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 ...
