Study of Nonclassical Fullerenes C_192 and C_204 with Seven Heptagon Rings

Sanchez-Bernabe F.J., Universidad Autónoma Metropolitana, MX

In this paper, we present some examples of nonclassical fullerenes with seven heptagon rings. For instance, a nonclassical fullerene with 192 carbons, seven heptagons, 19 pentagons, and 72 hexagons, is considered. Two of the seven [...]

Nonclassical Fullerenes C_60 and C_66 with Five Heptagon Rings

Sanchez-Bernabe F.J., Universidad Autónoma Metropolitana, MX

In this paper, we present a couple of examples of nonclassical fullerenes with five heptagon rings. The first of them, a nonclassical fullerene with 60 carbons, five heptagons, 17 pentagons, and 10 hexagons, is considered. [...]

Ceramic sintering and properties characterization based on solid mechanics

Camacho Montes H., Espinosa Almeyda Y., Gamboa Garay J.D., Barraza de León L.E., Vega Siverio A., Espinoza Ochoa I.M., Otero Hernández J.A., Rodríguez Ramos R., Mederos Madrazo B.J., Sabina F.J., Bordia R.K., Universidad Autonoma de Ciudad Juarez, MX

Ceramic processing can be tedious and time-consuming. Several techniques have been developed to face these complex processing. One of the most popular techniques relies on different approaches for Design of Experiments and/or statistical process control. [...]

PVA cryogels obtained by biomimetic synthesis of polyaniline using hematin supported on halloysite nanotubes as catalyst

Jiménez-Cárdenas P., De León-Santillán A., Gallardo-Vega C., Centro de Investigación en Química Aplicada, MX

We studied the biomimetic synthesis of polyaniline as an alternate route to prepare electrical conductive cryogels (ECC), unique structures that combine intrinsic conductivity and hydrogel properties. For that purpose, hematin a natural porphyrin with peroxidase-like [...]

Synthesis of polyaniline catalyzed by soybean peroxidase immobilized in halloysite nanotubes

Alvarado-Canché C., López-Martínez J., Romero-García J., Ledezma-Pérez A., De León-Santillán A., Gallardo-Vega C., Centro de Investigación en Química Aplicada, MX

Polyaniline is one of the most extended studied conducting polymer because of its simple synthesis, low cost, high conductivity and excellent environmental stability. Synthesis of this inherently conducting polymer can be carried by several methods, [...]

Mechanical Re-Design of a Wells Turbine Blade to improve the efficiency of the LIMPET Wave Energy Conversion System

Montes A., Centro de Enseñanza Técnica y Superior, MX

Renewable energies are told to be the future of energy generation for the world; nowadays, the wind sector is the one with more development in technology. However, there are two big sources of energy that [...]

The Industrial Revolution: From IIoT to Industry 4.0

The following work explains a tool used to diagnose the level of industry 4.0 of Baja California ́s industries (Mexico). The evaluated industrie are interested in increasing their technological level to take advantage of the [...]

Two Examples of Nonclassical Fullerenes with Dodecahedral Structure

Sanchez Bernabe F., Universidad Autónoma Metropolitana, MX

Two nonclassical fullerene are presented. The first one contains heptagonal faces, besides pentagons, and hexagons.This example contains 420 carbons. There are 60 heptagons. The number of hexagons is 80, and finally, we have 72 pentagons. [...]

Hydrogel Films with CNT for biosensing applications

Paloma V., Jorge C., Rodolfo E., Iberoamericana University, MX

Hydrogels have been probe to be an amazing material, we present and hydrogel that we formulated with a mix of carbopol 940 and PVA, the selection of this material is because they present a high [...]

Development of curcuminoids oil nanoemulsions produced by high-energy methods: Microfluidization vs ultrasonication.

Espinosa-Andrews H., Paez-Hernandez G., CIATEJ, AC, MX

Turmeric curcuminoids are phytopolylphenol pigments of Curcuma longa root used in foods due to their yellow-orange bright shades and to their antioxidant, anti-inflammatory, antiviral, antibacterial, antifungal, and anticancer activities. They are highly sensitive to pH, [...]
