We construct strongly anisotropic quantum droplets with embedded vorticity in the 3D space, with mutually perpendicular vortex axis and polarization of atomic magnetic moments. Stability of these anisotropic vortex quantum droplets (AVQDs) is verified by means of systematic simulations. Their stability area is identified in the parametric plane of the total atom number and scattering length of the contact interactions. We also construct vortex-antivortex-vortex bound states and find their stability region in the parameter space. The application of a torque perpendicular to the vorticity axis gives rise to robust intrinsic oscillations or rotation of the AVQDs. The effect of three-body losses on the AVQD stability is considered too. The results show that the AVQDs can retain the topological structure (vorticity) for a sufficiently long time if the scattering length exceeds a critical value.

Droplet generation has been utilized in various applications, including drug delivery, the fabrication of functional particles, and material synthesis. Achieving the goals of these applications requires droplet generation of a desired size. Microfluidic droplet generation offers precise control of droplet dimensions.

Quantitative imaging of alpha-emitting radionuclides is essential for accurate dosimetry in radiopharmaceutical therapy (RPT). This study evaluates the performance of inkjet-deposited Am sources imaged with the ionizing-radiation Quantum Imaging Detector (iQID), focusing on spatial resolution, substrate effects, and activity recovery. Line and areal phantom patterns were printed onto stainless steel, nickel, and gold-coated nickel substrates.

The "abnormal" properties of ice and liquid water can be explained by a hybrid quantum/classical framework based on objective facts. Internal decoherence due to the low dissociation energy of the H-bond and the strong electric dipole moment lead to a quantum condensate of O atoms dressed with classical oscillators and a degenerate electric field. These classical oscillators are either subject to equipartition in the liquid or enslaved to the field interference in the ice.

Site selectivity is fundamental to fabricating complex nanostructures. Herein, we introduce "In-Ex site selectivity," a novel mechanism for regulating deposition on a liquid template containing internal solid particles. The selectivity dictates whether deposition occurs on the interior (In) solid surface or the exterior (Ex) surface of the liquid template.

Organic/quantum dot light-emitting diode displays have recently been manufactured using inkjet printers, which require stable ink drops and strict control during the printing process. Combining Ansys Fluent and Ansys Mechanical simulations, this research establishes the conditions that stabilize the ink droplets. The feasibility of this approach is verified through a jetting simulation of Newtonian fluids with almost constant viscosity and a comparison of the simulation and experimental results.
