Tertiary fatty amide, N,N-dibutyldodecanamide (DBDA), has been synthesized and evaluated as a new environmentally friendly plasticizer for polyvinyl chloride (PVC). Homogeneous PVC/DBDA films containing from 10 to 40 w...

"The aim of this work is to evaluate the espina corona gum (ECG) as a sustainable viscosifier or filtration reducer additive in water-based drilling fluids (WBMs) as a potential replacement of guar gum (GG). ECG is a gal...

Introduction. The performance reliability of electric vehicles (EVs) is an important factor in evaluating their suitability for widespread adoption. The reliability and lifespan of an EV depend on several critical factor...

Low nano-SiO2 loaded nylon 6 (PA6) nanocomposites were readily produced via in situ polymerization. The effect of surface-modified functional groups of nano-SiO2 on the interfacial structure and properties of nylon 6/SiO...

The aim of this work was to synthesize and to characterize new pH-sensitive hydrogels that can be used in the controlled release of drugs, useful for dermal treatments or ophthalmology's therapies. Copolymers containing ...

This paper presents results of an investigation of the features of phase and structure formation of a ternary compound during thermal sintering use of compacted TiH2-Al-C powder blends. The thermal sintering was carried ...

Tesis Energía y Ambiente (maestría) - Instituto Tecnológico de Buenos Aires, Buenos Aires - Karlsruher Institut für Technologie, Karlsruhe, 2023 "The energy transition in the residential sector has witnessed substant...

We present the synthesis of three Mg(II) complexes potentially useful for magnesium supplementation in human and veterinary medicine: magnesium chloro-aspartate, Mg(C4H604N)Cl.3H2O; magnesium citrate, [Mg(H2O)6][MgC6H5O7...

En el presente trabajo se estudió la descomposición térmica del efavirenz (EFZ), un no-nucleótido que es inhibidor de la transcriptasa reversa de prolongada vida media, utilizando calorimetría diferencial de barrido...

"High-temperature renewable and industrial heat applications require efficient and compact solutions to address their inherent intermittency. Latent heat thermal energy storage is one such solution, acting as a buffer be...

"The following Master’s Thesis deals with the topic of the design and analysis of a reactor pressure vessel for a nuclear reactor concept meant for a high temperature application. This work finds itself within the work...

Com o objetivo de determinar os parâmetros térmicos do antiretroviral zidovudina (AZT) foram empregados a Calorimetria Exploratória Diferencial (DSC) e a Termogravimetria (TG). A curva DSC do fármaco indicou uma temp...

Este informe describe los resultados de un estudio in vitro en el que fueron evaluados comprimidos de nevirapina (200 mg) de diferentes laboratorios brasileros. El producto roiginal fue la refencia, en comparación con c...

O objetivo desse trabalho foi caracterizar através de métodos termoanalíticos e perfil de dissolução, formulações de comprimidos de metronidazol de cinco laboratórios (R, G, SA, SB, SC) comercializadas no mercado...

Powder mixtures (1:1) of tibolone polymorphic forms I (monoclinic) and II (triclinic) and excipients have been prepared and compacted. The samples were stored at 50 °C and 90% RH for one month and subsequently were eval...

El comportamiento térmico de la Auranofina, uno de los fármacos a base de oro mejor conocidos, fue investigado por análisis termogravimétrico y térmico-diferencial, en corriente de oxígeno. Fue posible postular un ...

The synthesis of La2(CO3)3.4H2O was carefully investigated, on the basis of the thermal behavior (TG and DTA measurements) of the corresponding octahydrate, used as the precursor. The analysis of the X-ray powder diagram...

"This thesis aims to develop a model for an industrial evaporative cooling system having a chiller and a production heat source using two cooling towers, to evaluate the energy consumption of the system and find an optim...
