Global warming and depletion of resources have fueled research towards innovative building materials low environmental impact high performance engineering properties. Porous glass-ceramics were synthesized using municipal solid waste incinerator (MSWI) bottom ash (BA) as a starting material. BA was initially milled then vitrified, purification step, by direct microwave heating, characterized gl...

Evaporation of saline solutions from a porous medium often leads to the precipitation of salt at the surface of the porous medium. It is commonly observed that the crystallized salt does not form everywhere at the porous medium surface but only at some specific locations. To explain this phenomenon, we consider efflorescence formation at the surface of a saturated heterogeneous porous column (f...

Bottom-Up Designed Porous Coaxial Twin-Electrodes In article number 2210638, Alexander Kuhn, and co-workers describe the redox cycling of molecules between two macroporous electrodes having a co-axial architecture. The bottom-up designed device, with easily tunable parameters, such as gap, thickness pore size individual electrodes, allows significant signal enhancement, opening interesting pers...

An electrically conducting nanofluid saturated with a uniform porous media has been tested to determine how rotation affects thermal convection. Utilizing the Oldroydian model, which incorporates specific effects of electric field, Brownian motion, thermophoresis, and rheological factors for distribution nanoparticles that are top- bottom-heavy, one may use linear stability theory ensure stabil...

Steady-state evaporation of a saturated liquid droplet and its levitation over a solid surface due to momentum-induced pressure in the vapor film is studied by solving the axisymmetric governing equation numerically. A previous on~ime~onal analysis shows that the distance (or gap) between the solid surface and the droplet decreases when the vapor can penetrate the solid. For porous layers, this...

We have studied the effect of oxidation on the propagation loss and surface roughness of silicon-on-oxidized-porous-silicon strip waveguides fabricated using proton-beam irradiation and electrochemical etching. A thin thermal oxide is formed around the core of the waveguide, enabling the symmetric reduction of core size and roughness on all sides. Significant loss reduction from about 10 dB/cm ...

in this paper, we have tried to find a solution for quick transfer of nuclear wastes from pools of cool water to dry stores to reduce the environmental concerns and financial cost of burying atomic waste. therefore, the rate of heat transfer from atomic waste materials to the outer surface of the container should be increased. this can be achieved by covering the bottom of the pool space with c...
