“…AlCuFe is a Dirac semimetal that can tune its Fermi energy (E f ) through doping and other means to change conductivity, making tunable optoelectronic devices [55,56]. Figure 7(a) shows the absorption spectrum at 313 K. It can be seen that as E f increases from 75 to 95 meV, the absorption spectrum undergoes a blue shift and exhibits a strong multiband absorption response.…”

This study introduces an innovative dual-tunable absorption film with the capability to switch between ultra-wideband and narrowband absorption. By manipulating the temperature, the film can achieve multi-band absorption within the 30-45 THz range or ultra-wideband absorption spanning 30-130 THz, with an absorption rate exceeding 0.9. Furthermore, the structural parameters of the absorption film are optimized using the particle swarm optimization (PSO) algorithm to ensure optimal absorption response. The absorption response of the film is primarily attributed to the coupling of guided mode resonance and local surface plasmon resonance effects. The film's symmetric structure enables polarization incoherence and allows for tuning through various means such as doping/voltage, temperature, and structural parameters. In the case of multi-band absorption response, the film exhibits good sensitivity to refractive index changes in multiple absorption modes. Additionally, the absorption spectrum of the film remains effective even at large incidence angles, making it highly promising for applications in fields like biosensing and infrared stealth.

“…The volume of fluid-continuum surface force (VOF-CSF) model has been developed to capture the interface motions with good mass conservation property, − in which the construction of phase interfaces is realized by calculating the volume fraction of phases in the control volume, and the sum of the volume fractions of all phases in each control volume is equal to 1. If the volume fraction of q th fluid in the cell is denoted as α q , the α q = 0 means that the cell is empty without q th fluid; α q = 1 means that the cell is filled with all q th fluids; while 0 < α q < 1 means that the cell contains q th fluid interface between the cell and one or more other fluids.…”

Effects of the rheological properties of non-Newtonian middle fluids on the formation dynamics of double emulsions in coflowing microfluidic emulsification are systematically ascertained by both experimental investigation and numerical simulation with a volume of fluid-continuum surface force model. In the experiments, with non-Newtonian fluids as the middle fluids for the generation of double emulsions, six various flow regimes, including dripping, jetting, transition, nonbreakup, parallel, and multicore regimes, are distinguished, and the corresponding formation mechanisms of such distinct flow regimes are further comprehensively revealed by analyzing the flow field structures and viscosity distributions inside the double emulsions. Particularly, a large flow velocity of the outer fluid only contributes to the generation of a transition regime but not a jetting regime because of the shear-thinning property of the non-Newtonian middle fluid. The regimes in the flow pattern diagrams dependent on the capillary number of the outer fluid, the Weisenberg number of the middle fluid, and the Reynolds number of the inner fluid are obtained. Besides, the size variation laws of double emulsions under various operation conditions are also illustrated. As the flow velocity of the middle fluid increases, the inner diameter of the resultant double emulsions remains constant within a specific range because the increase of the flow velocity always results in the decrease of the middle fluid viscosity, thus determining the nearly invariant viscous shearing force acting on the inner fluid. Finally, the prediction correlations for the dimensionless inner and outer diameters of double emulsions with several key dimensionless numbers are established, and the prediction errors are within ±10%. The results of this study provide valuable guidance for the preparation of monodisperse double emulsions with non-Newtonian fluids as the middle fluids in a controllable and precise manner.
