Critical parameters of refractory metals

, 2020
A method for calculating the critical point parameters of metals on the basis of a generalised van-der-Waals equation was worked out with data on the liquid phase density and the heats of vaporisation of these metals.

Temperature Dependence of Phonons in Elemental Cubic Metals Studied by Inelastic Scattering of Neutrons and X-Rays [PDF]

, 2009
The vibrations of atoms in a crystal (phonons) make up the majority of its entropy (or heat capacity), and these vibrations are typically modeled by simple harmonic oscillators.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Comparative Studies of Digestion Techniques for the Dissolution of Neodymium-Based Magnets

Metals, 2021
The digestion of neodymium (NdFeB) magnets was investigated in the context of recycling rare earth elements (i.e., Nd, Pr, Dy, and Tb). Among more conventional digestion techniques (microwave digestion, open vessel digestion, and alkaline fusion ...

Quantum criticality at the metal-insulator transition [PDF]

Physical Review B, 2001
We introduce a new method to analysis the many-body problem with disorder. The method is an extension of the real space renormalization group based on the operator product expansion. We consider the problem in the presence of interaction, large elastic mean free path, and finite temperatures.

Impact of Metal and Metal Oxide Nanoparticles on Plant: A Critical Review [PDF]

Frontiers in Chemistry, 2017
Un besoin croissant de nanotechnologies dans diverses industries peut entraîner une énorme dispersion des nanoparticules dans l'environnement dans les années à venir. Une préoccupation concernant l'interaction des nanoparticules avec la flore et la faune est soulevée en raison d'une charge croissante de celles-ci dans l'environnement.

Anodic dissolution of metals in oxide-free cryolite melts [PDF]

, 2005
The anodic behavior of metals in molten cryolite-alumina melts has been investigated mostly for use as inert anodes for the Hall-Héroult process. In the present work, gold, platinum, palladium, copper, tungsten, nickel, cobalt and iron metal electrodes ...
