Summary: The fine control of chiral light-matter interaction at the nanoscale using designed metamaterial architecture is a cutting-edge craft with applications in biosensing, quantum, and classic nanophotonics. A novel concept of a 3D chiral metacrystal is proposed, where chiroptical properties are finely tuned by in-plane and out-of-plane diffractive coupling, showing potential for enantiomeric detection and integration with quantum emitters.

Summary: In this study, a photonic Dirac-Weyl semimetal is proposed by introducing screw rotation symmetries into a spatial inversion symmetry-lacking system. A realistic metacrystal structure is designed for experimental consideration. The screw rotation symmetries are crucial for the existence of Dirac points, whose Z2 topology is revealed by the (010) surface states. Meanwhile, two pairs of ideal Weyl points at the same frequency are protected by D2d point group symmetries. The Dirac points and Weyl points reside in a clean frequency interval. The proposed photonic Dirac-Weyl semimetal provides a versatile platform for exploring the interaction between Dirac and Weyl semimetals and exploiting possible photonic topological devices.

Summary: By adjusting the relative weight of photonic and plasmonic components, the emergence of chiral surface lattice resonances (c-SLRs) in arrays of nanohelices has been achieved. This finding provides a new approach for engineering chiral plasmonic systems for sensing applications.

Summary: In this article, a novel electromagnetic metacrystal was designed, fabricated, and characterized, which topologically carries nontrivial nodal surface degeneracies compensated by charge-2 Weyl points. Experimental observations demonstrated the robust unidirectional transport supported by node surfaces, offering more degrees of freedom to engineer the dispersion of surface states. This system provides a platform to explore a new class of gapless topological electromagnetic wave systems.

Summary: Research has shown that liquid gallium oriented towards the direction of the substrate rubbing exhibits anisotropic reflection at 120 degrees Celsius, which increases on cooling and persists down to room temperature or below. Additionally, mechanical shear force induces anisotropic reflection, which relaxes after a few seconds.

Summary: In this study, the liquid-liquid equilibrium (LLE) and liquid-liquid-solid equilibrium (LLSE) data were determined for aqueous biphasic systems (ABS) composed of PEG, inorganic salts, and an ionic liquid (IL). The effects of the IL on the phase diagrams were investigated. The results showed that the IL had a small effect on the phase separation. The compositions and densities of the phases were determined, and the affinity of the IL for different phases was studied.

Summary: Liquid-phase microextraction (LPME) is an important technique for sample preparation that is widely used to extract various organic, inorganic, and pharmaceutical compounds from different environmental and biological matrices. LPME has three configurations - single drop microextraction, hollow-fiber liquid-phase microextraction, and dispersive liquid-liquid microextraction - each with different applications and advantages.

Summary: This study using molecular dynamics simulations found that water molecules form four adsorbed layers near the wall in quartz nanopores, exhibiting greater viscosity than bulk water. In the interface regions between n-alkanes and water, n-alkanes tend to align parallel to the pore wall, with longer n-alkanes showing a more pronounced alignment. Ignoring slip velocity can lead to an underestimation of n-alkanes flow rate by over 20%.

Summary: A pH-responsive hydrophobic deep eutectic solvent was utilized to develop a simple and efficient liquid-liquid microextraction method for the extraction of three parabens from personal care product samples. The separation of the solvent was achieved by changing the acidity of the sample solution. The optimal experimental conditions were determined using a central composite design, and the thermodynamic model of the solvent was investigated.
