Buffering of H+ and OHions in pure water probably represent the most primal physicochemical buffering phenomena, and their quantitative description is of great interest. In this context, “pure water” shall mean water without any solutes that could act as H+ buffers. In the following, it is understood that addition of H+ ions to pure water, or removal of H+ ions from it is carried out in the for...

The fabrication process of ceramic yttria-stabilized zirconia (YSZ) and nickel oxide nanofibers by electrospinning is reported. The preparation of hollow YSZ nanofibers and aligned nanofiber arrays is also demonstrated. The influence of the process parameters of the electrospinning process, the physicochemical properties of the spinning solutions, and the thermal treatment procedure on spinnabi...

Steep, short-crested waves, as well as a large variety of three-dimensional propagating wave patterns have been created in laboratory, utilizing a plunging half-cone. Monochromatic waves, over a range of frequencies and amplitudes through breaking and including soliton wave groups near resonance, have been observed and studied in a small wave flume. This monochromatic wavemaker creates complex ...

Monte Carlo (MC) and kinetic (kMC) models are widely used for studying the physicochemical surface phenomena encountered in most deposition processes. This spans from physical chemical vapor to atomic layer electrochemical deposition. MC kMC, comparison popular molecular methods, such as Molecular Mechanics/Dynamics, have ability address much larger time spatial scales. They also offer a far mo...

The transport of the antineoplastic drug doxorubicin (Adriamycin) in human red blood cells was investigated by measuring the net efflux from loaded cells. Previous data indicated that doxorubicin transport was a Fickian diffusion transport process of the electrically neutral molecule through the lipid domain of the cell membrane (Dalmark, 1981 [In press]). However, doxorubicin transport showed ...

During the last few years an increasing number of data bearing on certain gross biological processes have been interpreted in terms of definite physicochemical laws. Robertson, 1 for instance/has shown that the growth of human infants may be represented by the curve of an autocatalytic monomolecular reaction. The growth of animals as well as the growth of plants has also been shown to conform t...

The understanding of electrokinetic transport of fluid or particles in microchannel plays an important role in the design and the optimization of microand nanofluidic devices. Two important electrokinetic phenomena are electro-osmosis and electrophoresis. In order to study these phenomena, the lattice Boltzmann solver is coupled with the iteration solver for the Poisson equation. Using these nu...

The galvanic couple AA2024/Carbon Fiber Reinforced Polymer (CFRP) has been studied numerically and experimentally in a dynamic electrolyte droplet. As an electrolyte, NaCl droplet (0.6 M initial concentration) was used at controlled temperature (24.5°C) relative humidity (83.5%). evaporation of the monitored for 24 hours using Scanning Kelvin Probe (SKP), simulating atmospheric corrosion phenom...
