Fluctuations and stochastic noise in systems with hyperbolic mass transport

Jou, David; Galenko, Peter - In: Physica A: Statistical Mechanics and its Applications 366 (2006) C, pp. 149-158

fluctuations of the solute density and the solute diffusion flux. The role of the diffusion flux is analyzed in two descriptions …A binary system in which the diffusion flux has a nonvanishing relaxation time is considered. We study the spectra of …. First, the shortest observable time interval is shorter than the flux relaxation time, and the diffusion flux behaves as …

Witten's lectures on crumpling

Wood, A.J. - In: Physica A: Statistical Mechanics and its Applications 313 (2002) 1, pp. 83-109

Crumpling is a distortion brought about by a strong compression of a surface in which energy condenses in extremely small regions rather than being stored uniformly. Scaling laws describe how much energy goes into how little space. As crumpling of a sheet proceeds, a network of ridges and...

Membrane curvature induced by polymers and colloids

Lipowsky, Reinhard; Döbereiner, Hans-Günther; … - In: Physica A: Statistical Mechanics and its Applications 249 (1998) 1, pp. 536-543

Polymers and colloids change the ‘spontaneous’ curvature of flexible membranes such as lipid bilayers. Two general … cases will be discussed: (i) The effect of single polymers or colloids which are anchored or adsorbed to the membranes and …

Atomistic simulation of matter under stress: crossover from hard to soft materials

Romano, Antonino; Li, Ju; Yip, Sidney - In: Physica A: Statistical Mechanics and its Applications 304 (2002) 1, pp. 11-22

Atomistic simulation can give insights to the mechanical behavior of stressed crystalline hard materials. Theoretical strength, defined in the long wavelength limit through elastic stability criteria, or more generally in terms of soft vibrational modes in the deformed lattice, can be studied by...

Sol–gel preparation of polymethylsilsesquioxane aerogel membranes for CO2 absorption fluxes in membrane contactors

Lin, Yi-Feng; Ko, Chia-Chieh; Chen, Chien-Hua; Tung, Kuo-Lun - In: Applied Energy 129 (2014) C, pp. 25-31

investigated the CO2 absorption fluxes obtained using these aerogel membranes. The PMSQ aerogel membranes prepared with 17% NH4OH …-prepared PMSQ aerogel membranes can be used continuously to absorb CO2 for at least 4days, and they can be reused in three … consecutive cycles of CO2 absorption. The results of this study demonstrated that these as-prepared PMSQ aerogel membranes are not …
