(Elsevier Science, 2016-02)
In the present work, the structural, topological and vibrational properties of four members of the N-benzylamides series derived from Maca (Lepidium meyenii) whose names are, N-benzylpentadecanamide, N-benzylhexadecanamide, ...
Synthesis, crystal X-ray diffraction structure, vibrational properties and quantum chemical calculations on 1-(4-(4-Fluorobenzamido)phenyl)-3-(4-fluorobenzoyl)thiourea
(Elsevier Science, 2010-11)
The 1-(4-(4-Fluorobenzamido)phenyl)-3-(4-fluorobenzoyl)thiourea species (1) has been synthesized and characterized by GC–MS, elemental analyses and 1H NMR and FTIR spectroscopy techniques. The crystal structure of the novel ...
Anomalous thermodynamic properties in ferropericlase throughout its spin crossover transition
(AMER PHYSICAL SOC, 2009)
The thermodynamics properties of ferropericlase (Mg(1-x)Fe(x)O where x=0.1875) (Fp) throughout its spin crossover were investigated by first principles. Fp was treated as an ideal solid solution of pure high-spin and ...
Free Vibrations of Beam System Structures with Elastic Boundary Conditions and an Internal Elastic Hinge
(Hindawi Publishing Corporation, 2013-09)
The study of the dynamic properties of beam structures is extremely important for proper structural design. This present paper deals with the free in-plane vibrations of a system of two orthogonal beam members with an ...
Frictional properties of surface textures fabricated on hardened steel by elliptical vibration diamond cutting
(Elsevier Inc., 2019)
Surface texturing is a promising approach to tailor friction and wear between rubbing surfaces in mechanical components. In this study, surface textures with different geometries and shapes were fabricated on hardened steel ...
