The hardness and stiffness parallel to the rod axis results in high hardness and modulus, shown to have modulus values of 85–90 GPa and hardness values of 3.4-3.9 GPa. [66] The hardness and modulus in the direction perpendicular to the rod directions are lower values, shown to have an elastic modulus between 70 and 77 GPa and a hardness value ...
Sepiolite, [5] also known in English by the German name meerschaum (/ ˈ m ɪər ʃ ɔː m / MEER-shawm, /-ʃ əm /-shəm; German: [ˈmeːɐ̯ʃaʊm] ⓘ; meaning "sea foam"), is a soft white clay mineral, often used to make tobacco pipes (known as meerschaum pipes).
P11-4 is a self-assembling β-peptide. It builds a 3-D bio-matrix with binding sites for Calcium-ions serving as nucleation point for hydroxyapatite (tooth mineral) formation. The high affinity to tooth mineral is based on matching distances of Ca-ion binding sites on P11-4 and Ca spacing in the crystal lattice of hydroxyapatite.
Mineralized tissues combine stiffness, low weight, strength and toughness due to the presence of minerals (the inorganic part) in soft protein networks and tissues (the organic part). [ 1 ] [ 2 ] There are approximately 60 different minerals generated through biological processes, but the most common ones are calcium carbonate found in mollusk ...
Cross-section of a tooth. B is dentin. Dentin (/ ˈ d ɛ n t ɪ n / DEN-tin) (American English) or dentine (/ ˈ d ɛ n ˌ t iː n / DEN-teen or / ˌ d ɛ n ˈ t iː n / DEN-TEEN) (British English) (Latin: substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth.
Hyaline cartilage is the glass-like and translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs , nose, larynx , and trachea . [ 1 ] Hyaline cartilage is pearl-gray in color, with a firm consistency and has a considerable amount of collagen.
Using finasteride daily can reduce DHT levels by as much as 70 percent and encourage hair regrowth. Saw palmetto . Evidence suggests this natural ingredient may help reduce DHT levels, especially ...
