Pool boiling heat transfer of HFE-7100 on metal foams
(Elsevier, 2019-12-26)
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 ...
The interaction of metal oxide surfaces with complexing agents dissolved in water
(Elsevier Science Sa, 2000-01)
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. ...
Spatial distribution, bioavailability, and toxicity of metals in surface sediments of tropical reservoirs, Brazil
(2018-04-01)
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 ...
Theoretical study of the diffusion of alkali metals on a Cu(111) surface
(Elsevier, 1997)
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 ...
Quantification of active sites for the determination of methanol oxidation turn-over frequencies using methanol chemisorption and in situ infrared techniques. 1: Supported metal oxide catalysts
(American Chemical Society, 2001-10)
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 ...
Application of surface-active compounds of microbial origin to clean up soils contaminated with heavy metals
(CRC Press - Taylor & Francis Group, 2017)
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 ...
Adhesive Bonding of Resin Composite to Various Ni-Cr Alloy Surfaces Using Different Metal Conditioners and a Surface Modification System
(Wiley-Blackwell, 2009-12-01)
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 ...
Dynamics of RS-(Au-SR)x staple motifs on metal surfaces: From nanoclusters to 2D surfaces
(American Chemical Society, 2020-02-06)
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. ...
