Precious metals recovery from aqueous solutions using a new adsorbent material

Scientific Reports, 2021
Platinum group metals (PGMs) palladium, platinum, and ruthenium represent the key materials for automotive exhaust gas treatment. Since there are no adequate alternatives, the importance of these metals for the automotive industry is steadily rising. The

Tunning the tensile deformation behavior and mechanism of nickel-based superalloy CM247LC by adjusting ageing treatment

Materials Research Letters, 2023
We investigate the tensile deformation behavior and mechanism of nickel-based superalloy CM247LC, which has been subjected to various ageing treatment schemes, but possesses almost the same γ′ particle size, at 600°C.

Comparison of thermally and chemically reduced graphene oxides by thermal analysis and Raman spectroscopy

Journal of Thermal Analysis and Calorimetry, 2020
Graphene oxide (GO) is not only an intermediate in top-down graphene preparation, but it is also acknowledged for its convenient application when the hydrophobicity of graphene is a drawback.

Nonlinear analysis of spacecraft thermal models [PDF]

, 2010
We study the differential equations of lumped-parameter models of spacecraft thermal control. Firstly, we consider a satellite model consisting of two isothermal parts (nodes): an outer part that absorbs heat from the environment as radiation of various ...

Experimental study on the overall cooling effectiveness of nozzle guide vane under high temperature and high pressure

Case Studies in Thermal Engineering, 2022
This study presents the overall cooling effectiveness of a nozzle guide vane with impingement-effusion in the conditions of the high temperature and high pressure at the mass flow ratios from KG = 0.09 to KG = 0.14. The temperature ratios change from KT =

Thermal analysis of halotrichites [PDF]

Thermochimica Acta, 2007
Abstract Four halotrichites from different origins were analysed by thermogravimetric and differential thermogravimetric analysis. The halotrichites were analysed by powder X-ray diffraction and were phase pure. The chemical composition was analysed using EDX techniques.
