The search for new techniques to increase boiling heat transfer has been driven by more efficient and compact heat exchangers, especially in microelectronics and equipment with high thermal loads. Two-phase cooling systems ...

Upon exposure to liquid water or to aqueous solutions, the surfaces of metal oxide particles or films undergo a series of chemical reactions that are dictated to a large extent by the chemistry of the metal ions involved. ...

Depending on the environmental conditions, surface sediments can retain all the contaminants present and provide a record of the anthropic activities affecting the aquatic environment. In order to analyze the impacts on ...

We present a theoretical study of the diffusion of Li, Na and K on a Cu(111) surface. Various diffusional paths are identified and characterized in terms of kinetic parameters such as diffusion constants and activation ...

Methanol oxidation over metal oxide catalysts is industrially important for the production of formaldehyde, but knowledge about the intrinsic catalysis taking place is often obscured by a lack of knowledge as to the number ...

Faced with more and more stringent regulations, nowadays heavy metals are the environmental priority pollutants and are becoming one of the most serious environmental problems. A variety of remediation technologies are ...

Purpose: This study evaluated the effect of three metal conditioners [Metal Photo Primer (R) (MPP), Cesead II Opaque Primer (R) (OP), Targis Link (R) (TL)], and one surface modification system [Siloc (R) (S)] on the shear ...

Limited stability of metal nanoparticles hinders their long-term uses and applications. For metal nanoclusters, this is even more critical, as physicochemical properties rely on the structure of only a few hundred atoms. ...
