Frequency-dependent viscosity of salmon ovarian fluid has biophysical implications for sperm-egg interactions
<p>Gamete-level sexual selection of externally fertilising species is usually achieved by modifying sperm behaviour with mechanisms thought to alter the chemical environment in which gametes perform. In fish this can be accomplished through the ovarian fluid, a substance released with the eggs at spawning. While its biochemical effects in relation to sperm energetics have been investigated, the influence of the physical environment in which sperm compete remains poorly explored. Our objective was therefore to gain insights on the physical structure of this fluid and potential impacts on reproduction. Using soft-matter physics approaches of steady-state and oscillatory viscosity measurements, we subjected salmon ovarian fluids to variable shear stresses and frequencies resembling those exerted by sperm swimming through the fluid near eggs. We show that this fluid, which in its relaxed state is a gel-like substance, displays a non-Newtonian viscoelastic and shear-thinning profile, where the viscosity decreases with increasing shear rates. We concurrently find that this fluid obeys the Cox-Merz rule below 7.6 Hz and infringes it above, thus indicating a shear-thickening phase where viscosity increases provided it is probed gently enough. This suggests the presence of a unique frequency-dependant structural network with relevant implications on sperm energetics and fertilisation dynamics.</p>
Dynamic viscosity of liquid rubidium at different temperatures
<p><strong>Dynamic viscosity of liquid rubidium at different temperatures</strong></p> <p>Junjie Chen</p> <p>Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R. China</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com</p> <p> </p> <p>Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre. Rubidium and cesium often occur together in nature. Rubidium, however, is more widely scattered and seldom forms a natural mineral; it is found only as an impurity in other minerals, ranging in content up to 5 percent in such minerals as lepidolite, pollucite, and carnallite. Brine samples have also been analyzed that contain up to 6 parts per million of rubidium. In the principal commercial process of rubidium production, small amounts of rubidium are obtained from the mixture of alkali metal carbonates remaining after lithium salts are extracted from lepidolite. Primarily a potassium carbonate, this by-product also contains approximately 23 percent rubidium and 3 percent cesium carbonates. The primary difficulty associated with the production of pure rubidium is that it is always found together with cesium in nature and is also mixed with other alkali metals. Because these elements are very similar chemically, their separation presented numerous problems before the advent of ion-exchange methods and ion-specific complexing agents such as crown ethers. Once pure salts have been prepared, it is a straightforward task to convert them to the free metal. This can be done by electrolysis of the fused cyanide or by reduction with calcium or sodium followed by fractional distillation. Rubidium is difficult to handle because it ignites spontaneously in air, and it reacts violently with water to yield a solution of rubidium hydroxide and hydrogen, which bursts into flames. If a metal sample has a large enough surface area, it can burn to form superoxides. Rubidium superoxide is a yellow powder. Rubidium peroxides can be formed by oxidation of the metal with the required amount of oxygen. Rubidium forms two other oxides. Rubidium and cesium are miscible in all proportions and have complete solid solubility.</p> <p>Temperature (degrees Celsius), Dynamic viscosity (grams per meter per second)</p> <p>50 0.542</p> <p>100 0.435</p> <p>150 0.365</p> <p>200 0.316</p> <p>250 0.28</p> <p>300 0.252</p> <p>350 0.23</p> <p>400 0.212</p> <p>450 0.197</p> <p>500 0.185</p> <p>550 0.174</p> <p>600 0.165</p> <p>650 0.157</p> <p>700 0.15</p> <p>750 0.143</p> <p>800 0.138</p> <p>850 0.133</p> <p>900 0.128</p> <p>950 0.124</p> <p>1000 0.12</p> <p>1050 0.117</p> <p>1100 0.114</p> <p>1150 0.111</p> <p>1200 0.108</p> <p>1250 0.105</p> <p>1300 0.103</p> <p>1350 0.101</p> <p>1400 0.099</p> <p>1450 0.097</p> <p>1500 0.095</p> <p>1550 0.093</p> <p>1600 0.092</p> <p>1650 0.09</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.

Dynamic viscosity of liquid potassium at different temperatures
<p><strong>Dynamic viscosity of liquid potassium at different temperatures</strong></p> <p>Junjie Chen</p> <p>Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R. China</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com</p> <p> </p> <p>Potassium metal is soft and white with a silvery lustre, has a low melting point, and is a good conductor of heat and electricity. Potassium imparts a lavender colour to a flame, and its vapour is green. The potassium content of the Dead Sea is estimated at approximately 1.7 percent potassium chloride, and many other salty bodies of water are rich in potassium. The waste liquors from certain saltworks may contain up to 40 grams per litre of potassium chloride and are used as a source of potassium. Most potassium is present in igneous rocks, shale, and sediment in minerals such as muscovite and orthoclase feldspar that are insoluble in water; this makes potassium difficult to obtain. As a result, most commercial potassium compounds are obtained via electrolysis from soluble potassium compounds, such as carnallite, sylvite, polyhalite, and langbeinite, which are found in ancient lake beds and seabeds. Potassium is produced by sodium reduction of molten potassium chloride. Molten potassium chloride is continuously fed into a packed distillation column while sodium vapour is passed up through the column. By condensation of the more volatile potassium at the top of the distillation tower. Efforts to devise a scheme for commercial electrolytic production of potassium have been unsuccessful because there are few salt additives that can reduce the melting point of potassium chloride to temperatures where electrolysis is efficient. There is little commercial demand for potassium metal itself, and most of it is converted by direct combustion in dry air to potassium superoxide, which is used in respiratory equipment because it liberates oxygen and removes carbon dioxide and water vapour.</p> <p>Temperature (degrees Celsius), Dynamic viscosity (grams per meter per second)</p> <p>100 0.441</p> <p>150 0.358</p> <p>200 0.303</p> <p>250 0.263</p> <p>300 0.234</p> <p>350 0.211</p> <p>400 0.193</p> <p>450 0.178</p> <p>500 0.166</p> <p>550 0.155</p> <p>600 0.146</p> <p>650 0.138</p> <p>700 0.132</p> <p>750 0.126</p> <p>800 0.12</p> <p>850 0.115</p> <p>900 0.111</p> <p>950 0.107</p> <p>1000 0.104</p> <p>1050 0.101</p> <p>1100 0.098</p> <p>1150 0.095</p> <p>1200 0.092</p> <p>1250 0.09</p> <p>1300 0.088</p> <p>1350 0.086</p> <p>1400 0.084</p> <p>1450 0.082</p> <p>1500 0.081</p> <p>1550 0.079</p> <p>1600 0.078</p> <p>1650 0.076</p> <p>1700 0.075</p> <p>1750 0.074</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.

Dynamic viscosity of liquid sodium at different temperatures

China</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com</p> <p> </p> <p>Sodium is a chemical element. It is a soft, silvery-white, highly reactive metal. Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium metal can be easily cut with a knife and is a good conductor of electricity and heat because it has only one electron in its valence shell, resulting in weak metallic bonding and free electrons, which carry energy. Due to having low atomic mass and large atomic radius, sodium is third-least dense of all elemental metals and is one of only three metals that can float on water, the other two being lithium and potassium. The melting and boiling points of sodium are lower than those of lithium but higher than those of the heavier alkali metals potassium, rubidium, and caesium, following periodic trends down the group. Metallic sodium is generally less reactive than potassium and more reactive than lithium.</p> <p>Temperature (degrees Celsius), Dynamic viscosity (grams per meter per second)</p> <p>200 0.451</p> <p>250 0.387</p> <p>300 0.341</p> <p>350 0.306</p> <p>400 0.278</p> <p>450 0.255</p> <p>500 0.237</p> <p>550 0.221</p> <p>600 0.208</p> <p>650 0.196</p> <p>700 0.186</p> <p>750 0.177</p> <p>800 0.17</p> <p>850 0.163</p> <p>900 0.156</p> <p>950 0.151</p> <p>1000 0.146</p> <p>1050 0.141</p> <p>1100 0.137</p> <p>1150 0.133</p> <p>1200 0.129</p> <p>1250 0.126</p> <p>1300 0.123</p> <p>1350 0.12</p> <p>1400 0.117</p> <p>1450 0.115</p> <p>1500 0.113</p> <p>1550 0.11</p> <p>1600 0.108</p> <p>1650 0.106</p> <p>1700 0.105</p> <p>1750 0.103</p> <p>1800 0.101</p> <p>1850 0.1</p> <p>1900 0.098</p> <p>1950 0.097</p> <p>2000 0.096</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.

Dynamic viscosity of liquid lithium at different temperatures

For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. In general, viscosity depends on a fluid's state, such as its temperature, pressure, and rate of deformation. However, the dependence on some of these properties is negligible in certain cases. For example, the viscosity of a Newtonian fluid does not vary significantly with the rate of deformation. The dynamic viscosity of the fluid, often simply referred to as the viscosity.</p> <p>Temperature (degrees Celsius), Dynamic viscosity (grams per meter per second)</p> <p>200 0.566</p> <p>250 0.503</p> <p>300 0.453</p> <p>350 0.412</p> <p>400 0.379</p> <p>450 0.352</p> <p>500 0.328</p> <p>550 0.308</p> <p>600 0.29</p> <p>650 0.275</p> <p>700 0.261</p> <p>750 0.249</p> <p>800 0.238</p> <p>850 0.228</p> <p>900 0.219</p> <p>950 0.211</p> <p>1000 0.204</p> <p>1050 0.197</p> <p>1100 0.191</p> <p>1150 0.185</p> <p>1200 0.18</p> <p>1250 0.175</p> <p>1300 0.17</p> <p>1350 0.166</p> <p>1400 0.162</p> <p>1450 0.158</p> <p>1500 0.155</p> <p>1550 0.151</p> <p>1600 0.148</p> <p>1650 0.145</p> <p>1700 0.142</p> <p>1750 0.139</p> <p>1800 0.137</p> <p>1850 0.135</p> <p>1900 0.132</p> <p>1950 0.13</p> <p>2000 0.128</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.

The concentration of a vapor in contact with its liquid, especially at equilibrium, is often expressed in terms of vapor pressure, which will be a partial pressure if any other gas is present with the vapor. The equilibrium vapor pressure of a liquid is in general strongly dependent on temperature. At vapor-liquid equilibrium, a liquid with individual components in certain concentrations will have an equilibrium vapor in which the concentrations or partial pressures of the vapor components have certain values depending on all of the liquid component concentrations and the temperature. The converse is also true: if a vapor with components at certain concentrations or partial pressures is in vapor-liquid equilibrium with its liquid, then the component concentrations in the liquid will be determined dependent on the vapor concentrations and on the temperature. The equilibrium concentration of each component in the liquid phase is often different from its concentration in the vapor phase, but there is a relationship. The vapor-liquid equilibrium concentration data can be determined experimentally, approximated with the help of theories such as Raoult's law, Dalton's law, and Henry's law.</p> <p>Temperature (degrees Celsius), Pressure (kilopascals), Dynamic viscosity (milligrams per meter per second)</p> <p>220 600 241.68</p> <p>225 735 221.72</p> <p>230 894 203.75</p> <p>235 1075 187.48</p> <p>240 1283 172.67</p> <p>245 1519 159.13</p> <p>250 1786 146.69</p> <p>255 2085 135.2</p> <p>260 2419 124.3</p> <p>265 2790 114.63</p> <p>270 3203 105.21</p> <p>275 3658 96.44</p> <p>280 4160 87.89</p> <p>285 4712 79.64</p> <p>290 5315 71.47</p> <p>295 5984 63.01</p> <p>300 6710 53.33</p> <p>302 6997 48.3</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.

Kinematic viscosity of gas phase methane at different temperatures and pressures
<p><strong>Kinematic viscosity of gas phase methane at different temperatures and pressures</strong></p> <p>Junjie Chen</p> <p>Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R. China</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com</p> <p> </p> <p>For some applications the kinematic viscosity is more useful than the absolute, or dynamic, viscosity. Kinematic viscosity is the absolute viscosity of a fluid divided by its mass density. (Mass density is the mass of a substance divided by its volume.) The dimensions of kinematic viscosity are area divided by time; the appropriate units are metre squared per second. The unit of kinematic viscosity in the centimetre-gram-second system, called the stokes in Britain and the stoke in the U.S., is named for the British physicist Sir George Gabriel Stokes. The stoke is defined as one centimetre squared per second.</p> <p>Temperature (degrees kelvin), Temperature (degrees Celsius), Temperature (degrees Fahrenheit), Pressure (bars), Pressure (pound-force per square inch), Kinematic viscosity (centistokes)</p> <p>90.694 -182.46 -296.42 0.1170 1.696 14.51</p> <p>100 -173 -280 0.3438 4.986 5.926</p> <p>110 -163 -262 0.8813 12.78 2.751</p> <p>120 -153 -244 1.914 27.76 1.475</p> <p>130 -143 -226 3.673 53.28 0.8782</p> <p>140 -133 -208 6.412 93.00 0.5640</p> <p>150 -123 -190 10.40 150.8 0.3830</p> <p>160 -113 -172 15.92 230.9 0.2706</p> <p>170 -103 -154 23.28 337.7 0.1963</p> <p>180 -93.2 -136 32.85 476.5 0.1438</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.

Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases. Methane is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in water. It burns readily in air, forming carbon dioxide and water vapour; the flame is pale, slightly luminous, and very hot. Methane in general is very stable, but mixtures of methane and air, with the methane content between 5 and 14 percent by volume, are explosive. Explosions of such mixtures have been frequent in coal mines and collieries and have been the cause of many mine disasters. Methane is an important source of hydrogen and some organic chemicals.</p> <p>Temperature (degrees kelvin), Temperature (degrees Celsius), Temperature (degrees Fahrenheit), Pressure (bars), Pressure (pound-force per square inch), Absolute viscosity (micro-pascals-seconds), Absolute viscosity (centipoises)</p> <p>90.694 -182.46 -296.42 0.1170 1.696 204.5 0.2045</p> <p>100 -173 -280 0.3438 4.986 155.8 0.1558</p> <p>110 -163 -262 0.8813 12.78 121.3 0.1213</p> <p>120 -153 -244 1.914 27.76 97.43 0.09743</p> <p>130 -143 -226 3.673 53.28 79.87 0.07987</p> <p>140 -133 -208 6.412 93.00 66.33 0.06633</p> <p>150 -123 -190 10.40 150.8 55.44 0.05544</p> <p>160 -113 -172 15.92 230.9 46.27 0.04627</p> <p>170 -103 -154 23.28 337.7 38.12 0.03812</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.
