Here, we report the synthesis and experimental characterization of three drug-drug eutectic mixtures drug aminoglutethimide (AMG) with caffeine (CAF), nicotinamide (NIC) ethenzamide (ZMD). The i.e., AMG-CAF (1:0.4, molar ratio), AMG-NIC (1:1.9, ratio) AMG-ZMD (1:1.4, demonstrate significant melting point depressions ranging from 99.2 to 127.2 °C compared AMG (151 °C) also show moderately higher...

DTA analysis was used to investigate the solidification reactions of alloy A319 with either 12 or 136 ppm of Sr added. Strontium does not affect primary solidification of (Al) dendrites but modifies the kinetics of the (Al)–Si eutectic. The effects of Sr level and of cooling rate on the characteristic temperatures for the (Al)–Si and other eutectic reactions are described.

Despite their enormous synthetic relevance, the use of polar organolithium and Grignard reagents is greatly limited by their requirements of low temperatures in order to control their reactivity as well as the need of dry organic solvents and inert atmosphere protocols to avoid their fast decomposition. Breaking new ground on the applications of these commodity organometallics in synthesis unde...

The 4'-n-alkyl-4-cyanobiphenyls and 4'-n-alkoxy-4-cyanobiphenyls provide colourless liquid crystal phases which are chemically and photochemically stable. In many cases, the mesophases are produced at quite low temperatures, and indeed two members of the n-alkyl series are nematic at room temperature. Eutectic mixtures prepared from members of the two series give wide nematic ranges, e. g., fro...

Basic relationships between the phase diagrams, previously considered independent of each other, are described. Phase diagrams of two-component phosphatidylcholine/phosphatidylcholine (PC/PC), phosphatidylethanolamine/phosphatidylethanolamine (PE/PE), and PC/PE lipid membranes are systematically investigated by means of the Landau theory. While gradually changing the chain length of one of the ...

Background: Intravenous cannulation is a prerequisite before any major or minor surgical procedures. Objectives: The rationale of the study was to compare effectiveness eutectic mixtures local anesthetics (EMLA) cream and vapocoolant spray for pain reduction during intravenous (I.V.) cannulation. Methods: This observational prospective cohort done on 140 patients requiring I.V. prior elective p...

Increasing the sustainability of industrial processes implies substitution conventional solvents for others with less environmental impact. For its implementation, it is essential to know value thermodynamic and transport properties. In addition, having theories correlations predict their behaviour under varied conditions very interesting. this work, we performed thermophysical characterization...

Directional solidification of metal-gas eutectic (Gasar) is a novel process for making regular porous metals. This process is based on a solid-gas eutectic reaction involving a gaseous medium and a metal or a ceramic phase, and allows an easy control of the porosity, such as its pore size, pore orientation and morphology in a wide range by properly adjusting its melting and solidification condi...

Today`s telecommunications/datacom industry is coping with its own technical challenges in processing capabilities as it juggles demands for greater electrical performance and reduced sizes. Particularly hot in technical slate are automatic eutectic attachment techniques, which are desirable for high-performance and high-capacity die attach applications. Actually, the eutectic die attach techni...
