In this study highly pure carbons synthesized using resorcinol furaldehyde catalyzed with hexamethylenetetramine (an amine base) are tested for supercapacitor electrodes. This synthesis is not only from all-organic renewable sources, but can also significantly increase the performance of the...

A simple molecular thermodynamic approach is applied to the study of the adsorption of gases of chain molecules on solid surfaces. We use a model based on the Statistical Associating Fluid Theory for Variable Range (SAFT-VR) potentials [A. Gil-Villegas, A. Galindo, P.J. Whitehead, S.J. Mills,...

This study provides a systematic approach to understand the water tolerance of a newly developed non-catalytic biodiesel conversion process. The influence of water on the non-catalytic biodiesel conversion process was compared directly with the conventional transesterification reaction, which...

Based on random-walk diffusion, a microscopic model for drying is proposed to explain the characteristic features of the drying-rate curve of porous materials. The constant drying-rate period is considered as a normal diffusion process. The transition to the falling-rate regime is attributed to...

Power grids, road maps, and river streams are examples of infrastructural networks which are highly vulnerable to external perturbations. An abrupt local change of load (voltage, traffic density, or water level) might propagate in a cascading way and affect a significant fraction of the network....

The nonlinear theory of two-dimensional ion-acoustic (IA) solitary waves and shocks (SWS) is revisited in a dissipative quantum plasma. The effects of dispersion, caused by the charge separation of electrons and ions and the quantum force associated with the Bohm potential for degenerate...

Diffusers play a vital role in the supersonic separator to convert kinetic energy into pressure energy. The natural gas flows in diffusers were numerically calculated using the navier-stokes equations with the RSM (reynolds stress model). The behavior of gas dynamic parameters was analyzed under...

An existing curvilinear finite-volume code with robust shock-capturing scheme was modified to allow for simulations of supersonic flow for axisymmetric cone geometries. It is shown how for an axisymmetric coordinate system the convective and viscous flux derivatives in the circumferential...
