Photochemical machining can satisfy the large demand coming from the microproducts market. The metal etching technologies lack however a precise control over the micro-geometry of surfaces. Metal etching results from diffusive and kinetic phenomena whose relative importance depends on process parameters. The effects of the chemical kinetics on...

We propose a method for the estimation of the overall heat transfer coefficient to/from a fluid in a cylindrical pipe at high Peclet numbers from/to a medium with unknown temperature profile in the axial direction. The method uses an analytical solution of the heat equation in cylindrical coordinates subject to a Robin boundary condition and a...

We propose a method for the estimation of time dependent distributions of pressure head, water content, and fluid flow in homogeneous unsaturated soils with unknown lower boundary conditions using surface measurements only. The unknown boundary condition is replaced by a piecewise constant temporal function and the resulting discontinuity is...

Many successful methods for nanoparticle synthesis are based on a comminution of the phases containing the precursors prior to the chemical reactions. The beneficial effects of such techniques are well-known in terms of small dimensions and narrow distributions of diameters of the nanoparticles thereby produced. According to specific methods,...
