Americanae nace como un proyecto conjunto que surge dentro de la Red Europea de Información y Documentación sobre América Latina (REDIAL), y que ha afrontado la Biblioteca de la Agencia Española de Cooperación Internacional para el Desarrollo (AECID). Esta nueva biblioteca virtual hace más accesibles los libros digita…
Le graphène est un matériau constitué d'une seule couche atomique de carbone et représente un sujet majeur de la physique de la matière condensée. Le graphène possède de nombreuses propriétés remarquables : structure électronique décrite par une equation de Dirac sans masse, forte mobilité électronique, effet Hall qua…
Abstract While conventional structures are usually designed to fulfill a single primary purpose, smart structures add the ability to sense changes in their environment and use that information in a timely manner in ways that augment their functionality. Smart structures today are increasingly found in applications as…
Abstract Foamed cores are widely employed in lightweight structures, in particular, sandwich structures where they are used in alternative to honeycombs. Among the advantages compared to honeycombs foams show higher thermal and acoustic insulation and higher resistance to humidity and barrier to vapor and gases. Foame…
Abstract The natural fibers, lignocellulosic and protein, are well known to mankind from more than 7000 years BC. They are renewable and sustainable and are characterized by important properties such as good air permeability, hydroscopicity, and giving up moisture, no release of substances harmful to health, no allerg…
Abstract Polycarbonate (PC) is one of the most widely used consumer materials, both in its reinforced and unreinforced forms. The introduction of reinforcement improves mechanical and other properties while maintaining the desirable properties of PC, such as ease of manufacturing, chemical resistance, and thermal stab…
Abstract A brief overview of various compression and injection‐compression molding technologies for manufacturing of composites is presented. Important aspects involved in molding are considered, including molding schemes and various stages of processes, various compounds and ingredients used for their preparation, an…
Abstract Composite materials are widely used in marine applications. This article first introduces the marine environment. Then the most common marine materials are described, both laminates and sandwich materials, and examples are given for different surface and underwater vessels. Composites used in other marine str…
Abstract In the field of composites, the extrusion operation is mostly used to perform the continuous blending and compounding of both miscible and immiscible polymers, for carrying out chemical reactions and to remove volatile substances from the polymeric stream before its shaping. In the following sections of this…
Abstract Thermosets are highly cross‐linked polymers that are cured or set using heat, pressure, light, microwave and/or, energy devices. This leads to high performance products for industry because of their high modulus, strength, durability, and resistance toward thermal stress and chemical attacks as provided by th…
We investigate combined effects of topology and boundaries on the vacuum expectation value (VEV) of the fermionic current in the space with an arbitrary number of toroidally compactified dimensions. As a geometry of boundaries we consider two parallel plates on which the fermion field obeys bag boundary conditions. Al…
Abstract On the road to the development of nuclear fusion, the interaction of the hot plasma with the surrounding solid walls in a fusion reactor presents stringent requirements to be successfully met by the plasma‐facing materials. Indeed, the plasma‐facing materials are continuously submitted to extreme heat and par…
Modificações estruturais de resíduos para síntese de zeólitas é tema de muitos estudos\ndesenvolvidos na área de síntese de peneiras moleculares. Estes materiais são chamados de\npeneiras moleculares por possuírem tamanho de poros bem definido e por terem a capacidade\nde selecionar as moléculas pelo tamanho. Neste tr…
Abstract A micromechanical modeling procedure is presented to predict the effective mechanical properties of heterogeneous materials at finite strain. A repeating unit cell (RUC) is assumed to represent the microstructure of the heterogeneous materials. The response of RUC is evaluated for different equivalent macrosc…
Abstract The recycling of carbon fiber composites involves significant technical and economic challenges. Current work is focused on the development of efficient and cost‐effective methods to break down the matrix and extract the fibers without damaging the fibers or degrading their mechanical properties. There are se…
Abstract Thermoset composite systems, such as those based on epoxy resins, have been known for a long time. These systems suffer from a series of drawbacks, which include a limited number of fabrication processes, the inability to reuse scrap or rework cured parts, and a general lack of toughness. These drawbacks are…
Abstract Structural natural composites are synthesized and maintained by living organisms in mild conditions of temperature and pressure or in challenging aqueous saline environments unlike their synthetic counterparts, having remarkable properties. The study of the properties of bones, trees, or sea shells allows con…
Abstract Ceramic matrix composites today are being developed for applications in thermal structures, heat exchangers, and a number of applications involving extreme conditions. Nanofibers have great potential for enhancing the properties of ceramic composites. In the recent years, there has been a growing interest in…
In a glass of champagne, glittering, pearl-like bubbles rise. Why do most of them form at definite spots and according to which laws do they move to the surface?
Abstract Sandwich composite panels are being primarily utilized in many engineering sectors such as civil, infrastructure, mechanical, aerospace, marine, space, and nuclear industry primarily because of their high strength and stiffness to low weight ratio. This article considers primarily sandwich composite construct…
