Ferrosilite pyroxene is present in the mesostasis, which seems to have formed as the result of the chemical alterations plagioclase, and silica. The anorthite by nepheline plagioclase-rich chondrules is also a common phenomenon in chondrites. A related phenomenon, described by Itoh, is the metasomatic alteration of chondrule glass. • Pyroxenes are abundant minerals in basalt, peridotite

Polymer nanofibers can be used for the treatment of wounds of human skin. The Fine fibers of compatible polymers can be sprayed or spun onto the injured skin to form a fibrous mat dressing. This can let wounds heal by encouraging the formation of normal skin and its growth thereby eliminating scar tissue as found in a traditional treatment. Nonwoven nanofibrous membrane mats for wound dressing usually have pore sizes small enough to protect the wound from bacterial penetration via aerosol particle-capturing mechanisms.

The keratins are elements found in epithelial tissues while protective tissues such as hooves which are composed of “hard” keratins. Keratin also has been fabricated in the form of scaffolds, hydrogels and other forms to use as a novel biomaterial. In recent years owing to their ultra-structure, outstanding biocompatibility, and presence of cell interaction sites. Furthermore, simple,sustainable, and cheap extraction methods make it more assessable to use in the pharmaceutical technology for different applications

Carbon and glass–fiber reinforced PEEK has been used with advanced plastics technology in the redesigning of the helicopter blades profile, improving aerodynamic properties, and reducing overall weight. · The use of PEEK composites in the RAF Linx helicopter enabled it to break the world helicopter speed record. A good example of large-size fiber-reinforced components in aerospace application is the radome covering the underbelly radar on the Hercules transport aircraft. It is made from very thin polyethylene sulfide (PES) finterleaved with glass fiber cloth, which is subsequently hot molded in a closed state.

The FUN CAIs, have large isotopic mass fractionation effects coupled with nuclear anomalies in many isotopes (These CAIs show much larger mass fractionation effects than other CAIs). Has unclear nuclear anomalies are which associated with the large mass fractionations. The isotopic fractionation of silicon and magnesium in many FUN inclu- sions falls along the same trend as that of the normal CAIs but with much larger fractionations. There is strong evidence that these mass fractionation effects are the result of evaporative mass loss. Oxygen isotopic compositions of individual minerals in many FUN CAIs, as well as magnesium and silicon isotopic compositions of minerals in a forsterite-rich FUN CAI, suggest that these CAIs were crystallized.

Faster and better tissue regeneration by nano-HA may improve recovery and improve quality of life of patients. Nano-bioceramics are natural components of the bone structure. From the material perspective, bone is a composite consisting of nano-HA rods embedded into a type 1- collagen matrix. Nano-HA can also be used to made bioceramic medical materials, which may decrease the need of autografts and replace allografts.

Shape memory gels have been used for surgical procedures that require automatic healing for mechanical deformations and rapid closures for sutures. The potential of thermal-responsive gels to recall their initial structure upon a change in temperature after being deformed make them suitable for this application. Shape memory gels were prepared from acrylic acid and stearyl acrylate. The polymer experienced change in Fabrication of Hydrogel Materials for medical applications shape as the temperature changes. Such polymer assumed a deformed and a stable state in alcohol upon cooling.
