Enhanced thermal transport analysis of electromagnetic hybrid nanofluid flow in a variable Darcy porous medium with mixed convection and Thompson–Troian slip

Journal of Taibah University for Science
This work examines thermal transport of electrohydromagnetic (EMHD) hybrid nanofluid flow (HNF) through a variable Darcy regime. The flow is affected by suction and blowing effects when flowing on the surface of a sheet in combination of mixed convective

Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide

Advanced Materials, EarlyView.
An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...
