CaCO3 whiskers were incorporated into cement composites in this paper and the effects of whiskers on the physical properties of cement composites were studied, including the fluidity and dry shrinkage of mortar and the pore structure of cement paste. The results showed that the fluidity of cement mortar was decreased gradually with the CaCO3 whisker content increasing and when the whisker content...
In this study, a novel nano calcium phosphate biomaterial have been fabricated with the aim of finding a good candidate as scaffold for bone tissue engineering, in terms of porous structures and biocompatibility. The scaffold was investigated by a combination of X-ray diffraction, Fourier transform infrared spectroscopy, electron microscopy, mercury intrusion porosimetry and BET. It was shown that...
Summary form only given. Sintered Co(Cr)-MoB materials have a good combination of high modulus, high wear resistance, high corrosion resistance and adequate fracture toughness, making them suitable for many industrial applications such as metal-cutting tools and wear resistant components. In many applications, they are superior to oxide and carbide coatings. Recently, boride- based cermet surface...
Two step acid-base catalyzed silica xerogels which had integrated structure were prepared through sol-gel and ambient pressure drying. Silica xerogels powder, TiO2 powder and short fibers were added as the additives in order to improve the properties of silica xerogels. The porous structure was estimated by the means of nitrogen adsorption method and mercury intrusion porosimetry (MIP). According...
