AbstractWe have grown Si nanowhiskers on a Si{1111} surface via the vapor-liquid-solid (VLS) mechanism. The minimum diameter of the crystalline is 3nm and is close to the critical value for the effect of quantum confinement. We have found that many whiskers grow epitaxially or non-epitaxially on the substrate along the 〈112〉 direction as well as the 〈111〉 direction.In our growth procedure, we first deposited gold on a H-terminated Si{111} surface and prepared the molten catalysts of Au and Si at 500°C. Under the flow of high pressure silane gas, we have succeeded in producing the nanowhiskers without any extended defects. We present the details of the growth condition and discuss the growth mechanism of the nanowhiskers extending along the 〈112〉 direction.

<p><em>Effect of four types of diluents</em><em>s</em><em> and four concentration of DMSO (5%, 10%, 15% and 20%) against the motility of African catfish sperm were evaluated after storage at freezing temperatures. </em><em>The steps in preparation the 16 treatments combination of the diluents</em><em> </em><em>are </em><em>preparation of diluents, mixing </em><em>diluents </em><em>with DMSO, packing </em><em>of semen </em><em>in</em><em>to</em><em> 0.3-ml straw, equilibration of </em><em>semen </em><em>at 4 °C for 30 minutes, freezing </em><em>of </em><em>semen in nitrogen vapor liquid </em><em>at </em><em>a height of 6.5 cm for 10 minutes</em><em>,</em><em> and subsequent</em><em>ly</em><em> storage of </em><em>semen </em><em>in liquid nitrogen (-196</em><em> <sup>0</sup></em><em>C) for further analy</em><em>sis</em><em> </em><em>of </em><em>post-thawing motility (PTM). </em><em>The result showed that t</em><em>he highest level of motility of spermatozoa </em><em>was </em><em>in </em><em>treatment </em><em>P</em><em><sub>1</sub></em><em>D</em><em><sub>15 </sub></em><em>(45.7 ± 4.3%) and the lowest </em><em>was </em><em>in </em><em>treatment </em><em>P<sub>2</sub>D<sub>20</sub> (14.5 ± 13.2%). The best diluent </em><em>in </em><em>this observation </em><em>was </em><em>diluents containing NaCl, KCl, CaCl<sub>2</sub> and NaHCO<sub>3</sub>. The best concentration </em><em>was </em><em>DMSO 15%. While the best interaction between the concentration of DMSO diluents is P<sub>1</sub>D<sub>15</sub> treatments containing NaCl, KCl, CaCl <sub>2</sub> and NaHCO<sub>3</sub> with a combination of 15% DMSO concentration. </em><em>The </em><em>conclusion </em><em>of the research is that </em><em>diluents containing NaCl, KCl, CaCl<sub>2</sub> and NaHCO<sub>3</sub> with a combination of 15% DMSO concentration</em><em> can be used in </em><em>cryopreservation of African catfish semen</em><em>.</em></p>
