Crystal structure and tautomerism of 1-[N-(4-iodophenyl)]aminomethylidene-2(1H)naphthalenone
(Verlag Z Naturforsch, 2001)
1-[N-(4-Iodophenyl)]aminomethylidene-2(1H)naphthalenone (1) (C17H12NOI) has been studied by X-ray analysis, IR, H-1 NMR, UV and AM1 semi-empirical quantum mechanical methods. It crystallises in the monoclinic space group ...

Catalytic asymmetric nitroaldol (Henry) reaction with a zinc-Fam catalyst
(Amer Chemical Soc, 2008)
Ferrocenyl-substituted aziridinylmethanol (Fam-1) was used as a catalyst with zinc for the asymmetric nitroaldol (Henry) reaction. This catalyst worked with a variety of aldehydes (aromatic, aliphatic, alpha,beta-unsaturated, ...
The slab albedo and criticality problem for the quadratic scattering kernel with the H(N) method
(Carl Hanser Verlag, 2008)
The one speed, time independent neutron transport equation for slab geometry with quadratic anisotropic scattering kernel is considered. Albedo, transmission factor and criticality thickness are calculated by the H(N) ...
Preparation and characterization of sulfonyl-hydrazine attached poly(styrene-divinylbenzene) beads for separation of albumin
(Elsevier Science Bv, 2007)
Novel sulfonyl-hydrazine carrying poly(styrene-divinylbenzene), poly(S-DVB)-S-NH2 ion-exchange beads (size between 210 and 425 mu m) were prepared via suspension polymerization and, were first used as an ion-exchange support ...
Studies of Al-Ti AHoys by SEM
(Amer Inst Physics, 2007)
Al-Ti (1, 2 wt. %) alloys were investigated by Scanning Electron Microscopy (SEM). SEM observations and energy-dispersive x-ray analyses (EDX) showed that the phase structure of Al-Ti (1 %) alloy at 165 mu m/s is composed ...
Investigation of the microstructure of metal catalyzed cyclopentene co-norbornene polymers by spectral methods
(Springer, 2007)
For the first time, cyclopentene (CPE) has been copolymerized with the strained cycloolefin norbornene (NBE) using catalytic amounts of the electrochemically prepared metathesis catalyst. The microstructure of polymers was ...
Functional morphology of the venom apparatus of the funnel spider, Agelena gracilens (Araneae : Agelenidae) from Turkey
(Amer Entomol Soc, 2007)
The funnel-web spider, Agelena gracilens Koch C. L., 1841 is widely distributed throughout Middle Europe, Mediterranean countries, and Middle Asia. The aim of this study is to describe the functional morphology of the venom ...
Investigation of the pairing effect using newly evaluated empirical studies for 14-15 MeV neutron reaction cross sections
(American Physical Soc, 2007)
The asymmetry term effects for the cross sections of (n, charged particle) and (n,2n) reactions at 14-15 MeV neutron incident energy have been investigated. The effects of pairing and odd-even nucleon numbers in new data ...
Negative parity states and some electromagnetic transition properties of even-odd erbium isotopes
(American Physical Soc, 2007)
The negative parity states and some electromagnetic transition properties of even-odd erbium isotopes (Er-159,Er-161,Er-163,Er-165) were studied within the framework of the interacting boson-fermion model. The single fermion ...
