Identification of individual and few layers of WS2 using Raman Spectroscopy
(2013-04)"The Raman scattering of single-and few-layered WS2 is studied as a function of the number of S-W-S layers and the excitation wavelength in the visible range (488, 514 and 647 nm). For the three excitation wavelengths used ... -
Implementación de un algoritmo con el método de diferencias finitas en el dominio del tiempo para estudiar propiedades ópticas en metales
(2013)"Todos los fenómenos relacionados con los campos electromagnéticos son correctamente descritos por la teoría electromagnética desarrollada por James Clerk Maxwell en 1873, donde se conecta y se formula matemáticamente las ... -
Improvement and analysis of a pseudo random bit generator by means of cellular automata
(2010)"In this paper, we implement a revised pseudo random bit generator based on a rule-90 cellular automaton. For this purpose, we introduce a sequence matrix HN with the aim of calculating the pseudo random sequences of N ... -
In situ ion beam sputter deposition and X_ray photoelectron spectroscopy (XPS) of multiple thin layers under computer control for combinatorial materials synthesis
(Wiley, 2017)"Deposition of ultra_thin layers under computer control is a frequent requirement in studies of novel sensors, materials screening, heterogeneous catalysis, the probing of band offsets near semiconductor junctions and many ... -
In-plane anisotropy in BSCCO superconducting tapes: Transport and magnetometric criteria
(Elsevier, 2020)"Here, the anisotropy between the longitudinal and transverse directions of multi-filamentary Bi2Sr2Ca2Cu3O10+x tapes ("in plane" anisotropy) is studied by transport and magnetization measurements. By minimally manipulating ... -
Including transcription factor information in the superparamagnetic clustering of microarray data
(2010)"In this work, we modify the superparamagnetic clustering algorithm (SPC) by adding an extra weight to the interaction formula that considers which genes are regulated by the same transcription factor. With this modified ... -
Inferring mixed-culture growth from total biomass data in a wavelet approach
(Elsevier, 2006)"It is shown that the presence of mixed-culture growth in batch fermentation processes can be very accurately inferred from total biomass data by means of the wavelet analysis for singularity detection. This is accomplished ... -
Influence of Fe doping and magnetic field on martensitic transition in Ni–Mn–Sn melt-spun ribbons
(Elsevier, 2016-04)"Mn-rich Ni-Mn-Sn metamagnetic shape memory alloys exhibiting magnetostructural transformation are of a great potential as the base materials for solid-state refrigeration. With the aim of fine tuning of the transformation ... -
Influencia del carbono en la transformación martensítica de una aleación Heusler Ni-Mn-In
(2017-08)"Se estudió el efecto de la adición del carbono en la aleación Ni50Mn35In15, los porcentajes atómicos añadidos fueron 0.1, 0.2, 0.3, 0.5, 0.6, 0.8, 1.0 %. Las aleaciones se sintetizaron a partir de elementos de alta pureza, ... -
Inhibition of Fungal Growth Using Modified TiO2 with Core@Shell Structure of Ag@CuO Clusters
(American Chemical Society, 2019)"The photocatalytic disinfection (PCD) properties of TiO2 have attracted attention in the research communities because the produced reactive oxygen species (ROS) allow destruction of different types of microbes, such as ... -
Inhomogeneous barotropic FRW cosmologies with constant-shifted conformal hubble parameters
(2013)"It is known that the barotropic FRW system of differential equations for zero cosmological constant can be reduced to simple harmonic oscillator (HO) differential equations in the conformal time variable. This is due to ... -
Insiders and outsiders: comparing urban impressions between population groups
(ACM, 2017)"There is a growing interest in social and urban computing to employ crowdsourcing as means to gather impressions of urban perception for indoor and outdoor environments. Previous studies have established that reliable ... -
Insights into Equilibrium and Adsorption Rate of Phenol on Activated Carbon Pellets Derived from Cigarette Butts
