Pearl cufflinks in the organic matter

May have a similar role in organic matter and pearl cuff links between the aragonite crystals in order to affect the growth of aragonite crystals, and makes the pearl cufflinks Chinese crystal is different from the standard aragonite. calcium carbonate variant of energy the size of the order of arrangement of the calcium carbonate colloid, vaterite, aragonite, calcite. So aragonite unstable trend into calcite at room temperature. During the Spring Festival or participate in celebration dinner party and some other formal occasions, you should have to wear expensive cufflinks.  Such as the shells of some marine organisms, was originally composed of aragonite, but in the long process, the majority has been transformed into calcite.
Will cause the lattice distortion from the orthorhombic to the trigonal system change, which makes the pearl cufflinks in the aragonite crystal there is a difference after a certain time changes must be the standard aragonite. They wear more than two pieces of accessories and the mens cufflinks. Pearl cufflinks by the bead core and bead layer is composed of two parts (see Figure 2.2). Natural bead core is often sand or other granular material, some little pearl nucleus and nacre aragonite as the main ingredient for its inherent columnar, spear-like crystals perpendicular to each of the layers of surface arranged to form radial aggregates.
Figure 1 pearl cufflinks soluble organic matter infrared absorption spectra. Figure 2 pearl cufflinks insoluble organic infrared spectra. The mens cufflinks can most fully embody your own unique taste and personal charm.  Shown in Figure 2, the pearl cufflinks insoluble organic matter shell keratin shell keratin strong absorption peak 1655 cm - 1 and 1 524 cm-1 is a pair of strong pairs in the 3281 cm - 1, can be seen from Figure peak, which is more typical protein infrared absorption peaks, 3281 cm in-1 is C, = O carbonyl base of the stretching vibration, 1655 cm in-1 should be is the C = O bond amide I band of the stretching vibration, 1 524 cm in-1 should be is c = O key amide II bending vibration at 860 cm - 1, an obvious trough. In addition a weak absorption at 3072 cm-1, 2964 cm-1, 2930 cm-1, 2872 cm-1, l444 cm-1, 1398 cm-1, 1222 cm-1, 1163 cm-1, 1055 cm-1.
 Department peak. 3072 cm - 1 octave band of the NH deformation vibration, 700 cm in plane bending vibration of NH absorption band 1222 cm - 1 absorption of amide Ⅲ, it is the mixing of the CN stretching vibration and NH deformation vibration, 617 cm -1 0 = CN angle-vibration. Pearl cufflinks in the organic matter is one of the important reason of pearl cufflinks with superior mechanical properties. The mens cufflinks can most fully embody your own unique taste and personal charm.  In recent years, organic. Inorganic composite materials research is a hot topic in the field of materials science, and pearl cufflinks is a great organic-inorganic composite materials. It was found compared to the pearl cufflinks, shell and other bio-minerals and natural mineral calcium carbonate, its mechanical properties (such as elongation at break, fracture toughness) can be increased by several orders of magnitude, chemical composition, the only difference is that the former than the latter increase about 0.1-5% organic matter.
