15. Effect of Surfactant in Particle Shape and Thermal Degradation of Eggshell Particles
High energy ball milling and sonofragmentation were used successfully to reduce the crystallite size of calcium carbonate extracted from the eggshell. The ceramic was milled using either deionized water or stearic acid and then subjected to a subsequent size reduction by means of a tip horn. The thermal degradation of particles was influenced by the presence

18. Effect of adding fatty acids and surfactant on the functional properties of biodegradable films prepared with myofibrillar proteins from acoupa weakfish (Cynoscion acoupa )
Abstract This research aimed to assess the properties of biodegradable films prepared with lyophilized myofibrillar proteins (LMP) from fish filleting residues, fatty acids (stearic, palmitic, and caproic), and surfactant (SLS). The films were characterized to assess the effects of adding those components. Adding fatty acids and SLS resulted in more flexibl

19. Fish oil for human health: omega-3 fatty acid profiles of marine seafood species
Abstract The purpose of this study was to investigate the fat contents and fatty acid profiles of the edible meat of 13 different seafood species caught in the Northeastern Mediterranean coast. The fatty acid compositions of seafood species ranged from 27.68% to 36.59% saturated fatty acids, 8.99% to 35.84% monounsaturated fatty acids and 10.69% to 39.57% p

20. Influence of temperature and time during malaxation on fatty acid profile and oxidation of centrifuged avocado oil
Abstract Virgin oil from avocados (Persea americana Mill.) is obtained by mechanical processes after pulp malaxation at temperatures that minimize oxidation and improve separation. The objective of this study was to assess the effect of time (0, 20, 30, 40, 60, 120 and 180 min) and temperature (40 and 50 °C) conditions during pulp malaxation on extraction y

21. Superhydrophobic Copper Foam Supported Phase Change Composites with High Thermal Conductivity for Energy Storage
Superhydrophobic and superoleophilic oxidized copper foam (OCF) was prepared by oxidation of copper foam using (NH4)2S2O8 to generate rough surface then followed by modification with low surface energy substance polydimethylsiloxane (PDMS) and stearic acid (SA). Based on sperwetting, form-stable phase change materials (PCMs) composites were obtained by facil

22. Comparative analysis of niobium and vanadium carbide efficiency in the high energy mechanical milling of aluminum bronze alloy
Abstract This study aims to analyze the efficiency of niobium and vanadium carbides in the high energy mechanical milling of aluminum bronze alloy. Two series of experiments were made following the same steps for both niobium carbide (NbC) and vanadium carbide (VC) additions: 30 g of chips were weighed and placed in a stainless steel jar with 3 % of carbide

23. FATTY ACID ETHYL ESTERS FROM MICROALGAE OF Scenedesmus ecornis BY ENZYMATIC AND ACID CATALYSIS
Microalgae are an indispensable food source for the various growth stages of mollusks, crustaceans, and several fish species. Using a microalgae biomass present in the Amazonian ecosystem (Macapá-AP), we study extraction methods for fatty acid such as solvent extraction (magnetic stirring and/or Soxhlet) and/or hydrolysis (acid and/or enzymatic catalysis) f
