Abstract:

The present work provides a selective review of research activities that focus on the graphene oxide (GO) and zinc oxide (ZnO) hybrid nanomaterials and their physical characterizations. The graphene oxide nanoparticle was prepared by modified Hummer’s method and the nanohybrids of GO/ZnO prepared by chemical method. Nanohybrids were characterized by thermogravimetric analyzer to find the thermal stability of the hybrid material, the structural nature and crystal size by P-XRD, functional group identification and surface morphology by using FTIR & SEM technique. This method provides a facil

Abstract:

Current trends in science and engineering research are analyzed, together with an inventory of changes in the field of employment and practice in industry. The resulting demands on the university education of chemists and chemical engineers have been translated into a more or less continuous updating of the curriculum at the Department of Chemical Engineering and Chemistry of the Eindhoven University of Technology in the Netherlands. In general it can be said that the emphasis within education will have to shift from the knowledge of facts, towards the ability to apply this knowledge to the pr

Abstract:

Active educational methodologies promote students to take an active role in their own learning, enhance cooperative work, and develop a collective understanding of the subject as a common learning area. Cloud Computing enables the learning space to be supported while also revolutionizing it by allowing it to be used as a link between active methodology and students’ learning activities. A Cloud Computing system is used in conjunction with an active methodology to recognize and manage individual, group, and collective evidence of the students’ work in this research.

Abstract:

In this work, the research results of the synthesis and properties of the polyols with the oxamidoester group, obtained in the reaction of N-substituted morpholine-2,3-dione derivatives with excess of alkylene carbonates have been presented. Using these derivatives as polyol components, rigid foamed polyurethane materials of high thermal stability and mechanical strength have been obtained. New polyurethane foams obtained using hydroxypropyl morpholine-2,3-dione derivatives can be used as heat-insulating materials of operating temperature as high as 150°C.

Abstract:

A lot of recent research has focused on the study of biocatalysts and nanocatalysts to improve biodiesel production. However, knowledge of the thermodynamic properties of the reaction components is necessary. In this work, the enthalpy of formation and Gibbs free energy of formation for methyl to pentyl esters were calculated using the Gaussian quantum chemistry software (model B3LYP/6-31G(d, p)) and the group contribution method of Constantinou and Gani (MCG). The values obtained by both methodologies present certain differences in relation to the values in the literature. Thus, three correct

Abstract:

Metalloporphyrins (MPs) are known to catalyze in vitro a broad range of cytochrome P450-mediated reactions occurring in vivo. Most of the biomimetic research using MPs in oxidative catalysis has been directed towards the oxidation of organic compounds presenting significant reactivity features in one functional group. Much less effort has been made to imitate the oxidation of more complex molecules, with a range of functionalities, such as drugs or other xenobiotics. By varying the structure of the porphyrin, the metal ion, the oxidant, and the reaction conditions, it is possible to modulate t

Abstract:

Adaptive support ventilation (ASV) is a closed-loop ventilation, which can make automatic adjustments in tidal volume (VT) and respiratory rate based on the minimal work of breathing. The purpose of this research was to study whether ASV can provide a protective ventilation pattern to decrease the risk of ventilator-induced lung injury in patients of acute respiratory distress syndrome (ARDS). In the clinical study, 15 ARDS patients were randomly allocated to an ASV group or a pressure-control ventilation (PCV) group. There was no significant difference in the mortality rate and respiratory pa
