(Taylor & Francis, 2018)"In this research, we are reporting the treatment of tequila vinasse by a coagulation–flocculation process coupled with heterogeneous photocatalysis using two types of titanium dioxide nanoparticles, i.e. (1) commercial ... -
Trends in nanoscience, nanotechnology, and carbon nanotubes: a bibliometric approach
(2014)"Carbon nanotubes are currently one of the most important materials due to their strong mechanical resistance, light weight, and transport properties. Since the publication of Ijima’s paper on tubular carbon structures ... -
Tuning emission in violet, blue, green and red in cubic GaN/InGaN/GaN quantum wells
(Elsevier, 2016)"Light emission in the three primary colors was achieved in cubic GaN/InGaN/GaN heterostructures grown by molecular beam epitaxy on MgO substrates in a single growth process. A heterostructure with four quantum wells with ... -
Tuning the dedoping process of PEDOT:PSS films using DBU-solvent complexes
(Elsevier, 2018)"In this study, we report a successful simple technique to dedope pristine PEDOT:PSS films at room temperature by dipping the films into 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) mixes with different solvents such as dimethyl ... -
Two integrable classes of Emden-Fowler equations with applications in astrophysics and cosmology
(Walter de Gruyter GmbH, 2018)"We show that some Emden–Fowler (EF) equations encountered in astrophysics and cosmology belong to two EF integrable classes of the type d2z/dχ2=Aχ−λ−2zn for λ=(n−1)/2 (class 1), and λ=n+1 (class 2). We find their corresponding ... -
Two sprayer CVD synthesis of nitrogen-doped carbon sponge-type nanomaterials
(2018)"Nitrogen-doped carbon sponge-type nanostructures (N-CSTNs) containing coaxial multiwalled carbon nanotubes are synthesized at 1020?°C by using a modified chemical vapor deposition (CVD) arrangement. Here, the CVD reactor ... -
Two-dimensional DFA scaling analysis applied to encrypted images
(2015)"The technique of detrended fluctuation analysis (DFA) has been widely used to unveil scaling properties of many different signals. In this paper, we determine scaling properties in the encrypted images by means of a ... -
Two-dimensional tunneling in a SQUID
(2010-11)"Traditionally quantum tunneling in a superconducting quantum interference device (SQUID) is studied on the basis of a classical trajectory in imaginary time under a two-dimensional potential barrier. The trajectory connects ... -
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 ... -
