Saybolt Universal Seconds (orSUS) is an alternative unit for measuring viscosity. The efflux time is Saybolt UniversalSeconds(SUS) required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Universal viscometer - under a carefully controlled temperature and...
2.1 Fluids: properties and composition of displacing and displaced fluids used in the experiment The experiments were carried out at standard room temperature. Dyed methanol was injected as the displacing fluid into the porous medium saturated with a glycerol-water solution. Three glycerol-water solutio...
The fluorescence of the dyes crystal violet, auramine-O and eosin-Y has been studied as a function of pressure in glycerol and polyvinylalcohol at room temperature. The strong pressure sensitivity observed for the substituted methane dyes is related to the viscosity change of the fluid medium....
Inset: the linearity between log(I540/I415) and temperature. (d) Fluorescence lifetime of 10 mM 1 at 540 nm in ethylene glycol-glycerol mixtures with varied solvent viscosity. Inset: the linearity between logt and logg. indicated that the fluorescence increase and ratiometric responses of 1 ...
Fig. 1: Viscosity enhances cell migration and promotes an ARP2/3-mediated dense actin network at the leading edge. a,b, Speeds of MDA-MB-231 cells (a) and other indicated cell types (b) inside confining channels at prescribed viscosities. The red lines represent the median of ≥69 cells...
We controlled the temperature of the bottom surface using a temperature controller (S100 Blast Co.) and kept the top surface free. The room temperature is set to 22.1 by a standard air conditioner. We used glycerol 99% manufactured by SIGMA-ALDRICH and ethanol 99% purchased from Wako Pure ...
we performed a meta-analysis of the impact of water content and temperature on the viscosities of four deep eutectic solvents (glyceline, reline,N,N-diethylethanol ammonium chloride-glycerol,N,N-diethylethanol ammonium chloride-ethylene glycol), their components (choline chloride, urea, glycerol, et...
A microwave power of 0.24 mW was used to avoid signal saturation at low temperature. Rotational correlation time (τc) of T4L-S90R1 and T4L-S117R1 with different glycerol concentrations was estimated (S. A. Goldman 1972) (Oppenheim et al., 1996)). Briefly, EPR spectra of the label...
a mixture of 769.5 g of acrylonitrile and 92.3 g of vinylidene chloride was added over two hours while the reaction temperature was maintained between 70° and 75° C. After being heated at 70° C. for one hour, the reaction mixture was stirred overnight at room temperature. The viscosity...
(i.e., formulations in which fatty acid soap comprises >50%, preferably >50 to 80%, more preferably 55 to 80% by wt. and, more preferably, 60 to 80% by wt. of the formulation) typically have a solid or thick gel-like rheology at room temperature. Because of this rheology, such ...
