Kinetic study of Polydopamine synthesis and its use as a photocatalyst
(2023)
"The study of synthesis and characterization of polydopamine (PDA) using dopamine (DA) as the monomer and (hydroxymethyl)aminomethane (TRIS) as the buffer was carried out during this doctoral thesis. The effect of temperature ...
Fabricación de Memorias Resistivas Orgánicas basadas en Nanocompositos Polímeros-CNT
(2023-03-16)
"En este trabajo de tesis doctoral se estudió el efecto de la interacción entre nanotubos de carbono de pared múltiple funcionalizados (f-CNTs, por sus siglas en inglés) y una matriz polimérica en su comportamiento eléctrico ...
Trayectorias relativistas, ecuaciones de Frenet-Serret y aplicaciones a nanomateriales
(2023-03)
"En esta tesis, estudiamos el Jerk relativista y otras derivadas superiores cinemáticas en espacio-tiempo de Minkowski mediante el marco de Frenet-Serret generalizado. La importancia del marco de Frenet-Serret radica, en ...
Elastocaloric and Magnetocaloric Effects Linked to the Martensitic Transformation in Bulk Ni55Fe11Mn7Ga27 Alloys Produced by Arc Melting and Spark Plasma Sintering
(MDPI, 2022)
"The investigation of caloric effects linked to first-order structural transitions in Heusler-type alloys has become a subject of considerable current interest due to their potential utilization as refrigerants in solid-state ...
Synthesis and Characterization of α-Al2O3/Ba-β-Al2O3 Spheres for Cadmium Ions Removal from Aqueous Solutions
(MDPI, 2022)
"The search for adsorbent materials with a certain chemical inertness, mechanical resistance, and high adsorption capacity, as is the case with alumina, is carried out with structural or surface modifications with the ...
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 ...
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, ...
Facile synthesis of a TiO2-Al2O3-GnPs compound and its application in the photocatalytic degradation of Diuron
(Elsevier, 2022)
"New ternary materials TiO2-Al2O3-GnPs (TAG) were prepared by using an innocuous sol-gel method with a slight modification for the addition of graphene nanoplatelets (GnPs), under room temperature and atmospheric pressure. ...
Synthesis of hollow carbon spheres by chemical activation of carbon nanoparticles for their use in electrochemical capacitor
(Elsevier, 2022)
"Naphthalene combustion has been used to synthesize grams per hour of solid carbon spheres (CS). The carbon soot was activated by acid treatment consisting in a mixture of HNO3 and H2SO4 (1/3 v/v) to produce hollow carbon ...
Stability of FeVO4-II under Pressure: A First-Principles Study
(MDPI, 2022)
"In this work, we report first-principles calculations to study FeVO4 in the CrVO4-type (phase II) structure under pressure. Total-energy calculations were performed in order to analyze the structural parameters, the ...
