Electrohydrodynamics of a pair of leaky dielectric droplets on the solid substrate: A lattice Boltzmann study
In this work, the electrohydrodynamics of a pair of leaky dielectric droplets on a solid substrate is investigated by the phase-field-based lattice Boltzmann method. Different from a pair of suspended droplets that may coalesce or separate, two leaky dielectric droplets on the substrate exhibit more complex modes due to the effects of wettability and electric force. The results show that when a horizontal electric field is applied, five different modes with electrostatic attractive force are ob…

Suppression of capillary instability in a confined quantum liquid filament
Quantum Bose-Bose mixtures with strong attraction can form self-bound, liquid-like droplets stabilized by quantum fluctuations. Despite equilibrium densities much lower than those of classical liquids, these droplets exhibit finite surface tension and liquid-like behaviors. Recent experiments have demonstrated Rayleigh-Plateau instability in elongated droplets confined in an optical waveguide. Here we consider the case of an infinite filament and extend the theoretical description to include tr…

Weekend #Plankton Factoid 🦠🦐
When most people think about algal blooms, they envision bright green water. However, blooms can also be dark red, invoking the colour of blood. A number of groups can generate red pigment blooms including flagellates like red-tide species Karenia brevis and Heterosigma akashiwo, Alexandrium spp. (Shellfish poisoning), the green algae Botryococcus braunii turning…

Das #Leckerli zum Probieren:
Bei #Möhrenkuchen denke ich immer: Boah, voll gesund. 🤣 Wenn es witzig sein soll, könnt ihr zusätzlich Dekomöhren drauflegen. 🥕🍰 Ein köstlicher Kuchen, der nicht nur #Osterhasen

Pump-driven droplet electrohydrodynamics: deformation, pinch-off and recoalescence
We investigate pump-driven droplet electrohydrodynamics with an emphasis on deformation, pinch-off, and recoalescence. A thermodynamically consistent phase-field framework is developed that couples Nernst--Planck--Poisson electrodiffusion with incompressible Navier--Stokes--Cahn--Hilliard flow, and incorporates interfacial ionic pumps as prescribed surface fluxes. In the pump-free baseline, applied fields merely polarise the droplet and deformation is negligible. By contrast, surface-localised …

Optical tweezers assisted coupling of nematic droplets to gold nanoparticle cluster: Effect on whispering gallery modes
Dye doped liquid crystal (LC) microdroplets exhibit tunable optical resonances modulated by size, shape, temperature, and external perturbations. When a dye-doped nematic microdroplet is coupled to a gold nanoparticle cluster, near-field interactions enhance local electric fields, boosting fluorescence emission. Optical tweezers serve as a tool for the parking of dye doped nematic microdroplets on gold nanoparticle clusters, enabling the dynamic coupling and excitation of whispering-gallery mod…

To spur the construction of affordable, resilient homes, the future is concrete
When most Americans imagine a home, they picture a wood-framed house. But in an era of high housing costs and extreme weather events, precast concrete offers a mix of durability and efficiency.

GlobDB: A comprehensive species-dereplicated microbial genome resource
Over the past years, substantial numbers of microbial species' genomes have been deposited outside of conventional INSDC databases. The GlobDB aggregates 14 independent genomic catalogues to provide a comprehensive database of species-dereplicated microbial genomes, with consistent taxonomy, annotations, and additional analysis resources. The GlobDB is available at https://globdb.org/.

Stable hopfions in trapped quantum droplets
Hopfions are a class of three-dimensional (3D) solitons which are built as vortex tori carrying intrinsic twist of the toroidal core. They are characterized by two independent topological charges, \textit{viz}., vorticity $S$ and winding number $M$ of the intrinsic twist, whose product determines the \textit{Hopf number}, $Q_{H}=MS$, which is the basic characteristic of the hopfions. We construct hopfions as solutions of the 3D Gross-Pitaevskii equations (GPEs) for Bose-Einstein condensates in …
