Las tecnologías químicas han constituido uno de los soportes fundamentales para satisfacer algunas de las necesidades de la sociedad. Los reactores químicos industriales se usan para la fabricación de productos quím...

Ligado directamente a la asignatura Química que se dicta en el Programa de Educación a Distancia de la Universidad de Buenos Aires (UBAXXI), este material se propone ofrecer a los estudiantes herramientas conceptuales ...

Las globinas son una familia de proteínas solubles, que poseen un grupo hemo unido generalmente de manera no covalente a la proteína. Sus representante má famosos son la hemoglobina y la mioglobina, responsables del t...

Las sustancias húmicas son componentes fundamentales del suelo y aguas naturales, siendo mezclas complejas y heterogéneas de materiales polidispersos formados por reacciones químicas y bioquímicas durante la descompo...

Purpose – Fair assessment is a fundamental pillar for ensuring that evaluation results accurately reflect students' abilities without bias. This study aims to identify Differential Item Functioning (DIF) in the Final S...

Selenium (Se) is required at a fundamental physiological level in all animals. Adequate levels of Se are necessary for proper bone metabolism, iodine metabolism, immune function, reproductive success, and recruitment. Se...

Los monoterpenos y otros compuestos orgánicos volátiles emitidos por la vegetación(emisiones biogénicas) juegan un papel significativo en la química troposférica porsu participación en la formación de oxidantes f...

Raman scattering can provide information on molecular fingerprints, which have been widely applied in various fields of material science and nanobiotechnology. Notably, low interference with water molecules in obtaining ...

The relative importance of different processes and transitions in the appearance of non-LTE populations for the fundamental levels of ozone was studied by quantifying the kinetic law of every process and transition that ...

Aerosol–cirrus interactions remain a major source of uncertainty in climate models due to the complex interplay of aerosol properties, ice nucleation pathways, and atmospheric conditions. In this study, we investigate ...

Abstract Quantum-mechanical simulations provide the most fundamental description of matter, yet their computational cost commonly limits applications to systems containing at most thousands of atoms. Here, we present an ...

The reduction of carbonyl compounds, including ketones and aldehydes, to alcohols is a fundamental and important reaction in organic synthesis. One of the most ideal methods is catalytic hydrogenation, however, the hydro...

Eco-friendly approaches for nanoparticle synthesis have gained attention due to their sustainability and reduced environmental impact. Zinc oxide nanoparticles (ZnO NPs) exhibit versatile bioactivities, but conventional ...

Abstract Amine-functionalized solid adsorbents represent promising next-generation materials for efficient CO2 capture. However, their practical deployment is constrained by a fundamental trilemma balancing CO2 adsorptio...

The relentless pursuit of athletic excellence is shadowed by the equally persistent evolution of performance-enhancing drugs (PEDs). In recent years, the antidoping landscape has been profoundly shaped by the rise of two...
