Numerical simulation of electrokinetic flow in microfluidic chips
(Asociación Argentina de Mecánica Computacional, 2006-12)
Microfluidic chips are miniaturized analytical devices used in chemical, biological and medical applications. In most cases, fluids are conducted through microchannels by applying electric potentials and/or pressure ...
A bi-objective integer programming model for locating garbage accumulation points: A case studyUn modelo bi-objetivo de programación entera para localizar puntos de acumulación de residuos: un estudio de caso
(Universidad de Antioquia, 2019-05-07)
Aumentar la eficiencia en la gestión de los Residuos Sólidos Urbanos (RSU) es crucial para los gobiernos municipales, que son los que generalmente se encargan de la recolección, ya que esta actividad consume un porcentaje ...
A closer look into the physical interactions between lipid membranes and layered double hydroxide nanoparticles
(Elsevier Science, 2020-07)
Layered double hydroxide nanoparticles (LDH-NPs) constitute promising nanocarriers for drug and gene delivery. Although their cell internalization has been studied, the interaction between LDH-NPs and biological membrane ...
Why are trace amounts of chloride so highly surface-active?
(Elsevier Science Sa, 2019-05)
On many metals, small quantities of chloride are known to be adsorbed at potentials well below the potential of zero charge and to influence other electrochemical processes. In order to understand this behavior, we have ...
Phosphorus adsorption by a modified polyampholyte-diatomaceous earth material containing imidazole and carboxylic acid moieties: Batch and dynamic studies
(Royal Society of Chemistry, 2017-06)
The aim of this study was to investigate phosphorus removal in water by using a polyampholyte obtained by the reaction of methacrylic acid, ethylene glycol diglycidyl ether and imidazole by a one step synthesis, mixed with ...
Ab-initio and DFT calculationd on molecular structure, NBO, HOMO-LUMO study and a new vibrational analysis of 4-(dimethylamino) benzaldehyde
(Pergamon-Elsevier Science Ltd, 2015-01)
The experimental and theoretical study on the molecular structure and a new vibrational analysis of 4-(Dimethylamino) Benzaldehyde (DMABA) is presented. The IR and Raman spectra were recorded in solid state. Optimized ...
How far does the defect tolerance of lead-halide perovskites range? The example of Bi impurities introducing efficient recombination centers
(Royal Society of Chemistry, 2019-03)
One of the key properties of lead-halide perovskites employed in solar cells is the defect tolerance of the materials, in particular regarding intrinsic point defects, which mainly form shallow traps. Considering that high ...
Aqueous solvent effects on the conformational space of tryptamine: Structural and electronic analysis
(Springer, 2012-11)
The TRA (3-[2-aminoethyl]indole) is an important neurotransmitter with a close structural and chemical similarity to the neurotransmitter serotonin (5-hydroxytryptamine), and to melatonin (5-methoxy-N-acetyltryptamine), ...
Evaluating structures, properties and vibrational and electronic spectra of the potassium 2-isonicotinoyltrifluoroborate salt
(Elsevier Science, 2018-07)
The potassium 2-isonicotinoyltrifluorborate salt has been characterized by using FT-IR, FT-Raman and UV?Visible spectroscopies while its structural properties were studied by using B3LYP/6-31G* and B3LYP/6-311++G** ...
Nanoarchitectonics of metal organic frameworks and PEDOT layer-by-layer electrodes for boosting oxygen reduction reaction
(Royal Society of Chemistry, 2021-09)
We present a strategy for the integration of three building blocks in a functional interfacial nano- architecture in order to fabricate composite films with improved features towards the electrochemical oxygen reduction ...
