Alzheimer and Parkinson diseases, frontotemporal lobar degeneration and amyotrophic lateral sclerosis overlapping neuropathology start in the first two decades of life in pollution exposed urbanites and brain ultrafine particulate matter and industrial nanoparticles, including Fe, Ti, Al, V, Ni, Hg, Co, Cu, Zn, Ag, Pt, Ce, La, Pr and W are key players. Metropolitan Mexico City health crisis is in progress
(Frontiers Media S.A., 2023)The neuropathological hallmarks of Alzheimer’s disease (AD), Parkinson’s disease (PD), frontotemporal lobar degeneration (FTLD), and amyotrophic lateral sclerosis (ALS) are present in urban children exposed to fine particulate ... -
Controllable biosynthesis of small silver nanoparticles using fungal extract
(2016-04)"The search for reliable and eco-friendly methods for the production of nanoscale materials is an important aspect of nanotechnology. Silver nanoparticles (AgNPs) are of special interest because of their antimicrobial ... -
Environmental Nanoparticles Reach Human Fetal Brains
(MDPI, 2022)"Anthropogenic ultrafine particulate matter (UFPM) and industrial and natural nanoparticles (NPs) are ubiquitous. Normal term, preeclamptic, and postconceptional weeks(PCW) 8–15 human placentas and brains from polluted ... -
Heterojunction of CuO nanoclusters with TiO2 for photo-oxidation of organic compounds and for hydrogen production
(American Institute of Physics, 2020)"Heterojunctions of small CuO nanoclusters (synthesized by radiolysis) with TiO2 (commercial P25) induced a photocatalytic activity under visible light irradiation in a wide range of wavelengths due to the narrow bandgap ... -
Kinetic study of polydopamine sphere synthesis using TRIS: relationship between synthesis conditions and final properties
(Royal Society of Chemistry, 2023)The synthesis and characterization of polydopamine (PDA) using dopamine (DA) as the monomer and (hydroxymethyl)aminomethane (TRIS) as the oxidant is studied. The effect of temperature and TRIS concentration on the kinetics ... -
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 ... -
Magnetostatic model for magnetic particle aggregates with cylindrical shapes
(Sociedad Mexicana de Física, A. C., 2023)Building micro and macro sized structures using compacted magnetic nanoparticles is a widely used approach that has proven a great potential as the basis for novel materials made by design. These materials are made by ... -
Sleep matters: Neurodegeneration spectrum heterogeneity, combustion and friction ultrafine particles, industrial nanoparticle pollution, and sleep disorders—Denial is not an option
(Frontiers Media S.A., 2023)Sustained exposures to ubiquitous outdoor/indoor fine particulate matter (PM2.5), including combustion and friction ultrafine PM (UFPM) and industrial nanoparticles (NPs) starting in utero, are linked to early pediatric ... -
Superparamagnetic state in La0.7Sr0.3MnO3 thin films obtained by rf-sputtering
(Nature Publishing Group, 2020)"A novel superparamagnetic state has been observed in high quality La0.7Sr0.3MnO3 (LSMO) thin films directly grown by rf-sputtering on SiOx/Si(100) substrates. The films are nanostructured without grain boundaries, constituted ... -
Synthesis of carbon nano-onions doped with nitrogen using spray pyrolisis
(Elsevier, 2018)"In this work, we have synthesized carbon nano-onions (CNOs) doped with nitrogen and iron carbide core. These nanostructures were synthesized pyrolysing various alcohol-benzylamine reaction mixtures. These CNOs showed a ... -
Synthesis of ZnMn2O4 nanoparticles by a microwave-assisted colloidal method and their evaluation as a gas sensor of propane and carbon monoxide
(MDPI, 2018)"Spinel-type ZnMn2O4 nanoparticles were synthesized via a simple and inexpensive microwave-assisted colloidal route. Structural studies by X-ray diffraction showed that a spinel crystal phase of ZnMn2O4 was obtained at a ... -
Synthesis, characterization and magnetic properties of Co@Au core-shell nanoparticles encapsulated by nitrogen-doped multiwall carbon nanotubes
