“…The nanostructured hybrid scaffold can be manufactured by in situ crystallization of HAp in the polymer matrix by dispersing the HAp nanoparticles in the polymer [349,350,353,354,360,363,364], via HAp synthesis within the polymer matrix itself [365,366], or even via 3D printing [241,367,368]. Juhasz et al [360] incorporated nanoparticles of HAp and carbonated HAp (nCHA) into the polymer matrix of a poly-2-hydroxyethylmethacrylate/ polycaprolactone (PHEMA/PCL) hydrogel with a filler content of 10 wt%.…”

Hydroxyapatite (HAp) is a bioceramic widely studied due to its chemical similarity with the mineral component of bones. Besides, it is biocompatible, bioactive and thermodynamically stable in the body fluid what poses it as an attractive material for a wide range of applications in the biomedical field. Several efforts have been focused on the synthesis of particles of this material aiming to the precise control of size and morphology, porosity and surface area. HAp is widely used as an implant for bone tissue regeneration, as a coating for metallic implants and in a drug-controlled release. In this sense, the objective of this review is to gather information related to HAp, providing readers with information about synthesis methods, material characteristics and their applications.

“…Since the bonding process begins at the point B, the mean contact pressure at the interface between sheets can be shown as follows; Hwang et al [7] also proposed this mean contact pressures and Younesi et al [17] researched the contact surface, and then, a conclusion was drawn that the contact surface was different with other surfaces in sandwich rolling.…”

In this paper, sandwich rolling with symmetrical thickness and materials is intensively studied. The inner metal is out of touch with both upper and lower rolls in the sandwich sheets, and all the forces are delivered from upper and lower sheets. This special character makes the relative slip distance and elongation distance appear. Then, the defected length is formed during the sandwich rolling. It verifies that the point where both inner and outer metals have the same velocity is also the point where the two metals are both deformed. Slab method is first applied in predicting the defected length of the sandwich sheets. Sandwich rolling experiments with aluminum and copper are conducted. The results obtained in this paper are also compared with those measured in experiments and calculated by stream function model recorded in references. So the model can be used in the real work conditions. It is helpful to find the best shearing position in the head of the sandwich sheets. The cost of materials is reduced based on the present model. When sheets are rolled in continual rolling passes, the defected length can be more important and serious. Specifically, if the sheets are wide, expensive and multilayer, the shearing position can be more significant to the industrial application.
