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) ? ... -
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 ... -
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. ... -
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 ... -
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 ... -
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 ... -
Sustentabilidad energética: hidrógeno como combustible limpio en la generación de electricidad
(UNAM, 2022)"En este trabajo, se realiza una discussión sobre la generación de energía eléctrica a través de fuentes alternas que utilizan hidrógeno como combustible. Las celdas de combustible más populares son las de membrana de ... -
A Systematic Review on Opuntia (Cactaceae; Opuntioideae) Flower-Visiting Insects in the World with Emphasis on Mexico: Implications for Biodiversity Conservation
(MDPI, 2022)"Opuntia spp. are cacti with high ecological, economic and conservation interest in semiarid environments, particularly in Mexico. We conducted a systematic search of the existing peer-reviewed literature about the state ... -
Optical sectioning of unlabeled samples using bright-field microscopy
(National Academy of Science, 2022)"The bright-field (BF) optical microscope is a traditional bioimaging tool that has been recently tested for depth discrimination during evaluation of specimen morphology; however, existing approaches require dedicated ... -
Impact of Drought and Groundwater Quality on Agriculture in a Semi-Arid Zone of Mexico
(MDPI, 2022)"This paper analyzes the behavior of drought in the face of the impact of climate change and groundwater quality and its implications for agricultural production in a semi-arid area of northeastern Mexico. The pluviometric ... -
Distribution Patterns of Invasive Buffelgrass (Cenchrus ciliaris) in Mexico Estimated with Climate Niche Models under the Current and Future Climate
(MDPI, 2022)"In Mexico, buffelgrass (Cenchrus ciliaris) was introduced in the middle of the 20th century. Currently, buffelgrass has become an invasive species and has colonized various ecosystems in the country. In addition to its ... -
Linearolactone Induces Necrotic-like Death in Giardia intestinalis Trophozoites: Prediction of a Likely Target
