Conducting polymer nanofibers/nanowires especially with an oriented arrangement have attracted great attention because of their unique properties and promising potentiality in nanomaterials and nanodevices, and increasing development for biomedical and biotechnological applications. For example, polyaniline (PANI) is one of the most useful conducting polymers due to its facile preparation, environmental s Read More

With the energy challenges to come, development of renewable energy sources is becoming more and more topical. But, because these energies are irregularly supplied, their development is closely related to those of suitable energy storage systems. Among the existing technologies for storing thermal energy, latent heat storage appears to be of huge interest since it can lead to reduced size and cost. This paper reviews Read More

Laser Cladding process is one of the most relevant new processes on the industry. Laser Cladding can be applied as rapid manufacturing technique consisting on the direct deposition of metallic alloys layer-by-layer. The resulting parts present a near-net-shape and fully functional properties, which convert this process on a real alternative for the manufacturing of single or very short series of complex geometry parts. On the Read More

This paper deals with a Probabilistic Transformation Method (PTM) for structures that require Finite Element Analysis to evaluate their response. The Probabilistic Transformation Method (PTM) is an efficient reliability method to solve problems of mechanical systems with uncertain parameters. This method is readily applicable in the case where the expression between input and output of structures are available in explicit analyt Read More

Production of small and geometrically complex parts is a typical application of powder injection molding (PIM) process. The production of parts by PIM can produce a final texture with high roughness. The roughness is an important factor of the adhesion of the human cell on the implant. This intrinsic factor can facilitate high bone - implant fixation, but it reduces the corrosion resistance of implants. A design of a temporary scr Read More

This paper presents the most recent and important research trends on the friction and wear properties of diamond like carbon (DLC) coatings deposited on different types of materials.
