Ultrastructural analysis of Candida albicans when exposed to silver nanoparticles
(2014-10)"Candida albicans is the most common fungal pathogen in humans, and recently some studies have reported the antifungal activity of silver nanoparticles (AgNPs) against some Candida species. However, ultrastructural analyses ... -
Understanding the adsorptive and photoactivity properties of Ag-graphene oxide nanocomposites
(2013)"Nanocomposites of graphene oxide (GO) and silver nanoparticles (AgNPs) were synthetized using a practical photochemical silver functionalization. Their photocatalytic activities were evaluated with two dyes, Rhodamine B ... -
Understanding the electrochemistry of armchair graphene nanoribbons containing nitrogen and oxygen functional groups: DFT calculations
(Royal Society of Chemistry, 2020)"The surface and edge chemistry are vital points to assess a specific application of graphene and other carbon nanomaterials. Based on first-principles density functional theory, we investigate twenty-four chemical functional ... -
Understanding the ion-induced elongation of silver nanoparticles embedded in silica
(2017-04)"In this work we have studied the elongation of silver nanoparticles irradiated with 40 MeV Bromine ions by means of in situ optical measurements, transmission electron microscopy and molecular dynamics simulations. The ... -
UrBis: a mobile crowdsourcing platform for sustainable social and urban research in Mexico
(Springer, 2018)"Recently, the United Nations Human Settlements Program (UN-HABITAT) stated that cities in Mexico are steadily expanding, sometimes outstripping the rise in population by two-fold due to urban sprawl, and that 85% of the ... -
Vanishing Poynting Observers and Electromagnetic Field Classification in Kerr and Kerr-Newman Spacetimes
(Hindawi, 2022)"We consider electromagnetic fields having an angular momentum density in a locally nonrotating reference frame in Schwarzschild, Kerr, and Kerr-Newman spacetimes. The nature of such fields is assessed with two families ... -
Viscosity and normal stress forces of Lennard-Jones chains using reverse non-equilibrium molecular dynamics
(Taylor & Francis, 2017)"Reverse non-equilibrium molecular dynamics was applied for the calculation of the viscosity for different chain lengths. Each chain consisted of m tangent spherical sites, where m was 1, 2, 4, 8 or 16, respectively. From ... -
Visualizing individual microtubules by bright field microscopy
(2010-11)"Microtubules are slender (similar to 25 nm diameter), filamentous polymers involved in cellular structure and organization. Individual microtubules have been visualized via fluorescence imaging of dye-labeled tubulin ... -
Wastewater Contaminated with Hydrazine as Scavenger Agent for Hydrogen Production by Cu/Ti Nanostructures
(MDPI, 2021)"Cu/Ti photocatalysts were prepared by the sol-gel process with different copper loadings (1.0, 2.5, and 5.0 wt.%) and then thermally treated at several calcination temperatures from 400 to 600 °C. The materials were ... -
Water splitting behavior of copper-cerium oxide nanorods and nanocubes using hydrazine as a scavenging agent
(Elsevier, 2016)"A one-step microwave synthesis using neither a template surfactant nor strong molar NaOH concentrations is reported. Well shaped nanorod and nanocube CeO2 structures were achieved in 0.5 and 4 h at a maximum irradiation ... -
Wave transmission through periodic, quasiperiodic, and random one-dimensional finite lattices
(2013-02)"The quantum mechanical transmission probability is calculated for one-dimensional finite lattices with three types of potentials: periodic, quasiperiodic, and random. When the number of lattice sites included in the ... -
Wavelet characterization of hyper-chaotic time series
(Sociedad Mexicana de Física, A.C., 2018)A wavelet scaling numerical characterization of time series based on the variance of the wavelet coefficients is used for three well-known four-dimensional and one five-dimensional hyper-chaotic systems. We report several ... -
Wavelet multifractal detrended fluctuation analysis of encryption and decryption matrices
(2013)"In this paper, we study in detail the multifractal features of the main matrices of an encryption system based on a rule-90 cellular automaton. For this purpose we consider the scaling method known as the wavelet transform ... -
What TripAdvisor Can´t Tell: Crowdsourcing Urban Impressions for Whole Cities
(L'Oeil d'Or, 2016)"In the context of a number of emerging opportunities for citizen participation in Latin America, we present an overview of the SenseCityVity project developed in Mexico. The project goals are the design, implementation, ... -
Why Nose and Mouth Coverings are Highly Recommended to Impede SARS-Cov-2 Spread
(Walsh Medical Media, 2021)"In fourteen months the number of infected people with SARS-COV-2 has reached more than 159 millions and from those more than 3 million have resulted in death. There is now a consensus that the airborne saliva droplets, ... -
Words for nobel prizes
(2003)"We present the statistics of the significant nouns and adjectives of social impact figuring in the nominations of the Nobel prizes in Physics and Chemistry over the period of the awards from 1901 to 2001." -
Wrinkled nitrogen-doped carbon belts
