By treating the viscosity expression as a semiempirical formula where the experimental and numerically simulated self-diffusion coefficients available in the literature are used, the shear viscosities of nitrogen and carbon dioxide, both of which are treated as a rigid linear rotator with two sites, ...
[48], it shows that the transition from hadrons to quarks and gluons has behavior similar to helium, nitrogen, and water at and near their phase transitions in the ratio η/s. Near and below a critical temperature, Tc, the condensates of bosons or fermion pairs behave like superfluids, ...
or a group of the formula Y cR11―M, wherein each Y is independently a group of the formula each R11 is a divalent hydrocarbyl group, R12 is as defined above for R9 and R10, and M is H, hydrocarbyl, amino, an amide group, an amide-containing group, an acylamino group, an imid...
All real fluids (except superfluids, such as liquid nitrogen) have some resistance to stress and fluid flow, but a fluid that has no resistance to shear stress is known as an ideal fluid or inviscid fluid. A real fluid with a nonzero viscosity is called a viscous fluid. The study of ...
Dynamic viscosities for motor oils SAE 10 to 50 for temperatures ranging 0-100oC. Nitrogen - Prandtl number vs. Temperature and Pressure Figures and tables showing Prandtl number of nitrogen at varying temperarure and pressure, SI and Imperial units. ...
A 1500 mg/L quantity of diutan gum and 400 mL of scleroglucan biopolymer solution, respectively, were added to 20 high-temperature-resistant glass bottles with a volume of 12 mL, into which nitrogen was injected and sealed to remove the dissolved oxygen in the solution and prevent oxygen oxida...
After the immersion experiment with a liquid, the cantilever was washed with flowing 70% ethanol and deionized water for 1 min, and then gently dried with a nitrogen gun. inside a gas chamber (70 × 65 × 30 mm3; Figure 2a) which was composed of two throttle valves and a pressure ...

The reaction product was purified by dialysis, and the degree of aminoacetalization was estimated from the nitrogen content as given by the semimicro Kjeldahl method. The PVA was used unfractionated and its degree of polymerization, as determined by the viscosity method, was found to be between ...
The viscosity-dependent fluor- escence increase of 1 is mainly attributed to the inhibition of the PET process from the aniline nitrogen to 1,8-naphthalimide; the intro- duction of the PET mechanism in addition to the conventional TICT rotor design in 1 greatly improves its sensitivity on ...
