Using Static Culture Method to Increase the Production of Acetobacter Xylinum Bacterial Cellulose
Journal of Natural FibersBacterial cellulose is a natural polymer, usually produced through synthetic (chemically defined) or natural media. However, the current methods of bacterial cellulose production are not ideal because of their low productivity and large number of ...

Nonideal Compressible Fluid Dynamics of Dense Vapors and Supercritical Fluids
Annual Review of Fluid MechanicsThe gas dynamics of single-phase nonreacting fluids whose thermodynamic states are close to vapor-liquid saturation, close to the vapor-liquid critical point, or in supercritical conditions differs quantitatively and qualitatively from the textbook gas ...

Supercritical Fluid Processing of Polymers [PDF]
Polymers, 2019 The use of supercritical fluids instead of organic solvents has attracted the interest of numerous researchers, due to the unique peculiarities of supercritical fluids which are characterized by solvent powers comparable to those of liquid organic solvents, diffusivity comparable to those of gaseous substances and quasi-zero surface tension [...]

Hydrodynamic anomalies in supercritical fluid [PDF]
The Journal of Chemical Physics, 2014 Using the molecular dynamics simulations we investigate properties of velocity autocorrelation function of Lennard-Jones fluid at long and intermediate time scales in wide ranges of temperature and density. We show that the amplitudes of both the leading and the subleading time asymptotic terms of velocity autocorrelation function, a1 and a2, show ...
