Influencia de mucílago de nopal Cactus Opuntia ficus-indica en la durabilidad de mezclas de mortero para la construcción
(2023-06)"Durante la presente investigación se evaluó el efecto de adicionar mucílago de nopal en mezclas de mortero base cemento Portland. Se estudiaron tres tipos de mezclas, una mezcla testigo sin adición de mucílago de nopal, ... -
Effect of Silicon Nanoparticles on Tomato Plants Exposed to Two Forms of Inorganic Arsenic
(MDPI, 2022)"In the environment arsenic (As) can be found mainly as arsenite (AsIII) and arsenate (AsV), which are highly toxic and threaten food security. Currently, there is great attention on the effects of silicon dioxide nanoparticles ... -
Preparation of carbon materials from chromium-tanned leather shavings for the removal of dyes from aqueous solution
(Springer Nature, 2022)"Chromium-Tanned Leather Shavings are hazardous residues generated during leather processing. Since they contain considerable amounts of chromium, they represent a threat to life and the environment if managed improperly. ... -
Quasi-exactly solvable hyperbolic potential and its anti-isospectral counterpart
(Elsevier, 2022)"We solve the eigenvalue spectra for two quasi exactly solvable (QES) Schrödinger problems defined by the potentials V (x; ? ,?) = 4? 2 cosh4(x) + V1(? , ?) cosh2(x) + ? (? ? 1) tanh2(x) and U(x; ? , ?) = ?4? 2 cos4(x) ? ... -
Environmentally Toxic Solid Nanoparticles in Noradrenergic and Dopaminergic Nuclei and Cerebellum of Metropolitan Mexico City Children and Young Adults with Neural Quadruple Misfolded Protein Pathologies and High Exposures to Nano Particulate Matter
(MDPI, 2022)"Quadruple aberrant hyperphosphorylated tau, beta-amyloid, ?-synuclein and TDP-43 neuropathology and metal solid nanoparticles (NPs) are documented in the brains of children and young adults exposed to Metropolitan Mexico ... -
The value of biotic pollination and dense forest for fruit set of Arabica coffee: A global assessment
(Elsevier, 2022)"Animal pollinators are globally threatened by anthropogenic land use change and agricultural intensification. The yield of many food crops is therefore negatively impacted because they benefit from biotic pollination. ... -
Potential Flood Risk in the City of Guasave, Sinaloa, the Effects of Population Growth, and Modifications to the Topographic Relief
(MDPI, 2022)"The coastal city of Guasave, Sinaloa, located on the Mexican Pacific coast, is subject to extreme precipitation events, which have caused flooding with damage to the city’s infrastructure. The factors that influence ... -
Structure and photocatalytic activity of maleic anhydride-functionalized TiO2 nanoparticles by a simple method
(BMC, 2022)"Titanium dioxide (TiO2) nanoparticles were functionalized with maleic anhydride (MA). The extension of adsorbed MA on the TiO2 was evaluated by ultrasonic and magnetic stirring. Total Organic Carbon and Thermogravimetric ... -
Identification of Soil Arsenic Contamination in Rice Paddy Field Based on Hyperspectral Reflectance Approach
(MDPI, 2022)"Toxic heavy metals in soil negatively impact soil’s physical, biological, and chemical characteristics, and also human wellbeing. The traditional approach of chemical analysis procedures for assessing soil toxicant element ... -
Interactions between pH, reactive species, and cells in plasma-activated water can remove algae
(Royal Society of Chemistry, 2022)"Lightning strikes cause nitrogen to dissolve in water and form reactive nitrogen and oxygen species, which form natural fertilizers that can be absorbed through plant roots. Such processes during rainstorm events can be ... -
Removal of Heavy Metal Ions from Wastewater with Poly-?-Caprolactone-Reinforced Chitosan Composite
(MDPI, 2022)"Currently, the requirements for adsorbent materials are based on their environmentally friendly production and biodegradability. However, they are also related to the design of materials to sustain many cycles in pursuit ... -
Relativistic hyperbolic motion and its higher order kinematic quantities
(Sociedad Mexicana de Física, A.C., 2022)"We investigate the kinematics of the motion of an observer with constant proper acceleration (relativistic hyperbolic motion) in 1+1 and 1+3 dimensional Minkowski spacetimes. We provide explicit formulas for all the ... -
