Heat transfer enhancement for thermal energy storage using metal foams embedded within phase change materials (PCMs) [PDF]

, 2010
In this paper the experimental investigation on the solid/liquid phase change (melting and solidification) processes have been carried out. Paraffin wax RT58 is used as phase change material (PCM), in which metal foams are embedded to enhance the heat ...

Direct numerical simulations of mass transfer in square microchannels for liquid-liquid slug flow [PDF]

, 2008
Microreactors for the development of liquid-liquid processes are promising technologies since they are supposed to offer an enhancement of mass transfer compared to conventional devices due to the increase of the surface/volume ratio.

Influence of impeller top clearance structure on the wear characteristics of the impeller of an axial flow lead-bismuth pump

He jishu, 2023
BackgroundThe high-temperature liquid lead-bismuth metal has a scouring and wear effect on the head of the axial flow lead-bismuth pump impeller blades in a lead-cooled fast reactor system, causing the protective layer on the blade surface to break down ...

Suppression mechanism of weld appearance defects in tandem TIG welding by numerical modeling

Journal of Materials Research and Technology, 2021
In high-speed tungsten inert gas (TIG) welding, the premature solidification of liquid metal in low-temperature zone of molten pool results in the formation of weld appearance defects (WADs) such as undercut and humping weld.

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.
