(4) Natural rock and minerals At present, the natural mineral materials which can release anion has been reported, they are tourmaline, odd ice stone, the Wizards stone, ancient seabed layer mineral and the opal.
These minerals could be processed to nano-materials by ultra-fine grinding, modification and precise grading, then mixing with PAN-VAC/Clay or other polymers to prepare anion functional additives.

At present, autograft, allograft, xenograft and alloplasm materials could be used for repairing bone defects.
Calcium phosphates ceramics are frequently used as bone substitute materials because of their similarity to the mineral phase of bone, absence of antigenicity, and excellent osteoconductivity.
Materials and Methods Preparation of the ceramics Calcium phosphate ceramics was prepared by H2O2 foaming method and sintered at 1250ºC for 3 hours with wet-synthetic calcium phosphate powder.

According with different arrival time, emergency supplies can be divided into four classifications: life-saving supplies, engineering support materials, construction materials and reconstruction materials[3].
Life Rescue (LifeRescue) is a sub-class of ERSubstance class, which contains four kinds of materials: Defend Thing, Life Salvation, Life Support and Rescue Transport.
Project Build is a sub-class of ERSubstance, including Project Device, Project Material, Apparatus, Light Device, Communication Video and Transport.

Among all multiferroic materials, BiFeO3 (BFO) is one of the rare multiferroic materials, exhibiting both ferroelectric and antiferromagnetic properties at room temperature with its relatively high Neel temperature (TN = 653 K) and Curie temperature (TC = 1103 K) [5].In past decades, many efforts have been made to synthesize single phase BFO.
For sol–gel route, bismuth nitrate (Bi(NO3)3·5H2O) and iron nitrate (Fe(NO3)3·9H2O) were used as starting materials, citric acid as chelating agent, and 2-methoxyethanol as solvent.
For hydrothermal route, bismuth nitrate and ferric chloride (FeCl3·6H2O) were used as starting materials, potassium hydroxide (KOH) as  mineralizer.
