Identificación del "hueco de agua" y su relación con la latencia física en semillas del género Lupinus spp.de Jalisco,México.
(2011)"Latencia de semillas es el estado en el cual una semilla viable no germina aunque se le coloque en condiciones de humedad, temperatura y concentración de oxígeno idóneas para hacerlo. Se considera que la función principal ... -
Immobilization of bimetallic oxyhydroxides on graphitic matrices to remove arsenate and fluorides from water
(2022-06-28)"The excess of arsenic and fluoride in the water has led to serious health problems, which is why they are considered a priority pollutant to be eliminated from drinking water by the World Health Organization (WHO). Various ... -
Immobilization of humic substances on metal-oxides(nano) particles and their impact in redox processes.
(2012)"Durante las dos últimas décadas se ha demostrado que el uso de sustancias húmicas (SH) y sus análogos (quinonas) pueden servir como mediadores redox (MR), acelerando la velocidad de reducción de diferentes contaminantes ... -
Impact of anthropogenic disturbances on the diversity of shallow stony corals in the Veracruz Reef System National Park
(2011-03)"Anthropogenic disturbances may affect the development and maintenance of coral reefs by promoting diseases and other syndromes. In turn, this may cause local decreases in coral species diversity. In this study, we compared ... -
Impact of emerging, high-production-volume graphene-based materials on the bioavailability of benzo(a)pyrene to brine shrimp and fish liver cells
(Royal Society of Chemistry, 2018)"With increasing commercialization of high volume, two-dimensional carbon nanomaterials comes a greater likelihood of environmental release. In aquatic environments, black carbon binds contaminants like aromatic hydrocarbons, ... -
Impacto de sustancias húmicas inmovilizadas en la reducción de compuestos aromáticos nitrogenados.
(2009)"Los compuestos nitrogenados aromáticos forman parte del grupo de contaminantes prioritarios. Dentro de esto grupo, la liberación al ambiente de los colorantes azo (R-N=N-R) es indeseable tanto por sus efectos estéticos ... -
Impacto dos mediadores redox na remoção de cor de corantes azo e antraquinônico por lodo granular anaeróbio sob condições mesofílicas e termofílicas
(2007)"Investigou-se o efeito de diferentes mediadores redox (MR) na remoção de cor de corantes azo e antraquinônico pelo uso de lodo granular anaeróbio sob condições mesofílicas (30ºC) e termofílicas (55ºC). Comprovou-se em ... -
Importancia de un árbol tropical (Dendropanax arboreus) para aves migratorias neárticas en México
(2009)"En sus sitios reproductivos diversas especies de aves migratorias se alimentan principalmente de insectos, sin embargo, durante su migración en los neotrópicos comen cantidades significantes de frutos. Este estudio a ... -
Improve in CO2 and CH4 adsorption capacity on carbon microfibers synthesized by electrospinning of PAN
(MDPI, 2019)"Carbon microfibers (CMF) has been used as an adsorbent material for CO2 and CH4 capture. The gas adsorption capacity depends on the chemical and morphological structure of CMF. The CMF physicochemical properties change ... -
Improved conductivity and anti(bio)fouling of cation exchange membranes by AgNPs-GO nanocomposites
(Elsevier, 2018)"Nafion and Ultrex membranes were modified with nanocomposites (NCs) of silver nanoparticles (AgNPs) immobilized on graphene oxide (GO) as a thin film, using a polydopamine adhesive (pda). The morphological, physicochemical, ... -
Improved predictions of the geographic distribution of invasive plants using climatic niche models
(2016-05)"Climatic niche models for invasive plants are usually constructed with occurrence records taken from literature and collections. Because these data neither discriminate among life-cycle stages of plants (adult or juvenile) ... -
Improved reductive transformation of iopromide by magnetite containing reduced graphene oxide nanosacks as electron shuttles
(Elsevier, 2019)"The novel application of magnetite containing reduced graphene oxide nanosacks (MrGO-N) as electron shuttles to improve the reductive degradation of the pharmaceutical pollutant, iopromide (IOP), was evaluated. MrGO-N ... -
In search of sulfate-reducing consortia able to degrade acetate under acidic conditions
(Wiley, 2020)"BACKGROUND Sulfate-reducing microorganisms (SRM) can help to remediate acidic effluents containing metals. One drawback of sulfate reduction is that some SRM do not completely oxidize the substrate to CO2 and acetic acid ... -
In vitro inhibitory activity of Acca sellowiana fruit extract on end products of advanced glycation
(2018)"Introduction Hyperglycemia plays an important role in the pathogenesis of diabetic complications, as it increases protein glycation, as well as the progressive accumulation of advanced glycation end products (AGEs), which ... -
