Abstract: A method is provided for determining the surface viscosity of a liquid in which a thread is formed from a drop of the liquid. The thread is lengthened and its minimum radius h0 is determined at multiple times between the thread formation and thread pinch-off. The minimum radius and associated time values are used to determine a linear relationship of minimum radius and time, with the coefficient of the linear relationship, or the slope X of the line in the linear relationship, corresponding to the surface viscosity μs of the liquid according to one of the following equations:

Abstract: A metal-ion deposition regulator to regulate the flux and deposition of metal ions in an electrochemical cell. The regulator containing two membranes made of a polymer and a plurality of two-dimensional porous nanosheets sandwiched between the two membranes. The regulator is capable of distributing flux of metal ions passing through the metal-ion deposition regulator and regulating the deposition of the metal ions onto the cathode or anode thereby suppressing dendrite growth in the electrochemical cell. An electrochemical cell containing an anode, a cathode, a liquid electrolyte, and a metal-ion deposition regulator. A method of making a metal-ion deposition regulator. The method includes fabricating two-dimensional porous nanosheets utilizing graphene oxide as an expendable template, and sandwiching the porous nanosheets between two membranes made of a polymer such that the nanosheets are in contact with the two membranes.

Abstract: A method for predicting yield and composition changes during urea inclusion fractionation to select a fatty acid methyl ester source for biofuel. The method can include heating a solid urea inclusion compound to a decomposition temperature, allowing the solid urea inclusion compound to decompose, heating again to a melting temperature, allowing the solid urea to melt, cooling to the decomposition temperature, and cooling again to a temperature below the decomposition temperature. Each heating, cooling, decomposing, and melting step can have its change in enthalpy and entropy recorded. A thermodynamic model can be calculated using the recorded changes in enthalpy and entropy. The thermodynamic model can predict a yield and composition of the solid urea inclusion compound and can be used to select a fatty acid methyl ester source using the predicted yield and composition.
