    Abstract: Nano-hydroxyapatite (nHA) are fine particles, and its crystal structure is similar to the inorganic composition of natural bone, similar to ordinary hydroxyapatite, nHA has higher solubility biocompatibility and excellent osteogenicity, especially in repair of bone defects. In recent years, nHA as a new oral material is widely used in various field... Show More

    Abstract: The need to recycle critical materials from spent lithium-ion batteries is undisputed. However, non-critical and currently low-cost elements such as manganese are often neglected. Looking at the development of this technology, however, it is evident that the demand for high-purity manganese for battery production will also increase enormously. The ... Show More
  • Study of Piezoelectric Properties of Barium Titanate for Energy Harvesting System Using COMSOL

    Abstract: The conversion of mechanical energy created by environmental vibrations into electrical energy is the main advantage of piezoelectric materials. An energy harvester with the help of photoelectric sensor using non-toxic Barium titanate is studied and a model of energy harvester unit is simulated in COMSOL multiphysics software package. This simulati... Show More
