Photoanodes modified with reduced graphene oxide to enhance photoelectrocatalytic performance of B-TiO2 under visible light
(2015)"The effect of reduced graphene oxide (rGO) content in boron-modified TiO2 nanocrystalline films on their photocatalytic activity in phenol oxidation is investigated. Visible-light-active TiO2 modified photoanodes were ... -
Photocatalytic properties of BiOCl-TiO2 composites for phenol photodegradation
(Elsevier, 2018)"BiOCl-TiO2 composites were synthesized by sol-gel method; using two commercial BiOCl (P2600 and SB) with different BiOCl-TiO2 weight ratios. They were characterized by different techniques such as X-ray diffraction (XRD), ... -
PI-controlled bioreactor as a generalized Liénard system
(Elsevier, 2007)"It is shown that periodic orbits can emerge in Cholette’s bioreactor model working under the influence of a PI-controller. We find a diffeomorphic coordinate trans-formation that turns this controlled enzymatic reaction ... -
Pine-tree-like morphologies of nitrogen-doped carbon nanotubes: Electron field emission enhancement
(2014)"Nitrogen-doped multiwalled carbon nanotube (CNT) bundles exhibiting pine-tree-like morphologies were synthesized on silicon-silicon oxide (Si/SiO2) substrates using a pressure-controlled chemical vapor deposition process. ... -
Planar motion with Fresnel integrals as components of the velocity
(Sociedad Mexicana de Física, A.C., 2020)"We analyze the two-dimensional motion of a rigid body due to a constant torque generated by a force acting on the body parallel to the surface on which the body moves extending an old note of Ferris-Prabhu [Am. J. Phys. ... -
Planeación en la era de las pandemias; una visión de futuro
(Academia Mexicana de Ciencias, 2020)"La pandemia ocasionada por el SARS-CoV-2 ha puesto al mundo entero al borde del colapso económico y de salud. Sorprende la falta de previsión en muchos países, México entre ellos. Tenemos la certeza de que otros eventos ... -
Plasmonic sensing of aqueous-divalent metal ions by biogenic gold nanoparticles
(Hindawi Publishing Corporation, 2019)"The chemical interaction between biogenic gold nanoparticles (AuNPs) and several metal (II) ions can be regarded as a practical, twofold, colorimetric, and plasmon resonance sensing method for the recognition of some ... -
Platinum nanoclusters in silica: Photoluminescent properties and their application for enhancing the emission of silicon nanocrystals in an integrated configuration
(2016-09)"We studied photoluminescence of ion implanted platinum nanoclusters embedded in silica. Pt ions were implanted at 2 MeV and the Pt nanoclusters were then nucleated by thermal treatment under either argon, air, or a reducing ... -
Polystyrene grafting of CNx nanotubes for the elaboration of polystyrene-based nanocomposites.
(2007)"This thesis is concerned to the development of novel engineered surface materials using nitrogen-doped carbon nanotubes (CNx) that were grafted with polystyrene (PS) chains using in situ radical polymerization controlled ... -
Population and Transcriptomic Changes of the Tropical Fish Parasite Caligus confusus (Copepoda: Caligidae) with Seasonal Variations in Sea Temperature
(MDPI, 2023)Fish–parasite systems could be subject to two scenarios under climate change: (i) increased water temperature might enhance parasite metabolism, allowing the parasite to spread rapidly; (ii) parasitism could decrease if ... -
Practical mediated-assembly synthesis of silver nanowires using commercial Camellia sinensisextracts and their antibacterial properties
