Nonlinear second order Ode's: factorizations and particular solutions
(2005)
"We present particular solutions for the following important nonlinear second order differential equations: modified Emden, generalized Lienard, convective Fisher, and generalized Burgers-Huxley. For the latter two equations ...
Effect of packing on the cohesive and electronic properties of methanofullerene crystals
(2008-07)
"The crystal structure, cohesive energy, and electronic properties of bulk phases of the fullerene derivative [6, 6]-phenyl-C(61)-butyric-acid-methyl-ester (PCBM) have been calculated using ab initio density-functional ...
Loop formation in graphitic nanoribbon edges using furnace heating or Joule heating
(2009-07)
"Here the authors report the use of either furnace heating or Joule heating to pacify the exposed graphene edges by loop formation in a novel graphitic nanoribbon material, grown by chemical vapor deposition. The edge ...
Intertwined magneto-optical and plasmonic effects in Ag/Co/Ag layered structures
(2009-09)
"Surface plasmon polariton (SPP) excitation effects on the magneto-optical (MO) activity of Au capped Ag/Co/Ag trilayers are studied as a function of Co thickness. An enhancement of the transverse MO Kerr signal under SPP ...
Raman spectroscopy study of heat-treated and boron-doped double wall carbon nanotubes
(2009-07)
"We performed Raman spectroscopy experiments on undoped and boron-doped double walled carbon nanotubes (DWNTs) that exhibit the "coalescence inducing mode" as these DWNTs are heat treated to temperatures between 1200 C and ...
Pure and doped boron nitride nanotubes
(2007-05)
"More than ten years ago, it was suggested theoretically that boron nitride (BN) nanotubes could be produced. Soon after, various reports on their synthesis appeared and a new area of nanotube science was born. This review ...
Competing magnetic structures and magnetic transitions in Er(2)Ni(2)Pb: powder neutron diffraction measurements
(2008-07)
"We have studied the magnetic structures of Er(2)Ni(2)Pb using a powder neutron diffraction technique in zero field. Previous bulk measurements suggested three distinct magnetic phase transitions. Our neutron diffraction ...
Enhanced tunneling through nonstationary barriers
(2007-11)
"Quantum tunneling through a nonstationary barrier is studied analytically and by a direct numerical solution of Schrödinger equation. Both methods are in agreement and say that the main features of the phenomenon can be ...
Aleación de Disprosio-Níquel en forma de cinta y método de síntesisNickel-Dysprosium alloy in a tape form and synthesis method
(2008-07)
"La presente invención describe y reclama una nueva aleación del compuesto intermetálico DyNi2 en forma de cinta. Asimismo, se describe una cinta útil para la refrigeración magnetocalórica a bajas temperaturas formada por ...
High-gain nonlinear observer for simple genetic regulation process
(Elsevier, 2007)
"High-gain nonlinear observers occur in the nonlinear automatic control theory and are in standard usage in chemical engineering processes. We apply such a type of analysis in the context of a very simple one-gene reg-ulation ...
