Abstract Transition metal oxides (TMOs) are considered as promising anode materials for lithium-ion batteries in comparison with conventional graphite anode. However, TMO anodes suffer severe volume expansion during charge/discharge process. In this respect, a porous Fe 2 O 3 nanorod-decorated hollow carbon nanofiber (HNF) is designed via combined electrospinning and hydrothermal method followe...

Potassium (K) is one of the main and most hazardous trace species released to gas-phase during thermochemical conversion biomass. Accurate experimental data models K release are needed better understand chemistry involved. Tunable diode laser absorption spectroscopy (TDLAS) used for simultaneous real-time in situ measurements atomic K, water (H2O) gas temperature vicinity (boundary layer) bioma...

Journal: :International Journal of Thermophysics 2022

Abstract In our previous work (J Chem Eng Data 2021, 66(3):1385–1398), a residual entropy scaling (RES) approach was developed to link viscosity [a thermodynamic property calculated with an equation of state (EoS)] using simple polynomial for refrigerants. Here, we present extension this much wider range fluids: all pure fluids and their mixtures whose reference EoS experimental data are availa...
