Transfer of metals in the liquids of electronic cigarettes

open access: yesInhalation Toxicology, 2020
Objectives: E-cigarettes are electronic devices containing a liquid that usually consists of a mixture of glycerol, propylene glycol and nicotine, with or without flavorings, in various concentrations. A vapor or aerosol is produced, and inhaled from the user, when this liquid is heated by a heating coil.

Phase-transfer photolysis of metal hexacarbonyls [PDF]

open access: yesOrganometallics, 1992
The photochemical conversion of M(CO)6 (M = Cr, Mo, W) to M(CO)5X- (X= halogen) across a hexam/ water interface leads to a separation of the reactant and product. This process may be of general lmportence for synthetic applications. Under suitable conditions inner- filter and secondary photolysis can be avoided.

Coulomb Drag and Heat Transfer in Strange Metals

open access: yesPhysical Review Letters, 2023
We address Coulomb drag and near-field heat transfer in a double-layer system of incoherent metals. Each layer is modeled by an array of tunnel-coupled SYK dots with random inter-layer interactions. Depending on the strength of intra-dot interactions and inter-dot tunneling, this model captures the crossover from the Fermi liquid to a strange metal ...

Thermal and exergetic analysis of Metal Foam-enhanced Cascaded Thermal Energy Storage (MF-CTES) [PDF]

open access: yes, 2013
Metal Foam-enhanced Cascaded Thermal Energy Storage (MF-CTES) has been proposed to solve the problem of poor heat transfer during heat exchange process, which is caused by unavoidable decrease of temperature differences. This paper conducts a theoretical
