Summary: This study explores the non-equilibrium interfacial behaviors of thermotropic liquid crystals and finds that the reordering of the liquid crystals is mainly caused by interfacial shearing. Simple methods for mapping interfacial velocities and investigating surfactant-driven flows are established, revealing the importance of surface advection and surfactant desorption. The dynamic states adopted by the liquid crystals in the presence of surfactant concentration gradients offer new opportunities for engineering complex fluids beyond equilibrium.

Summary: Rochelle salt, as the initiator of piezoelectrics and ferroelectrics, can greatly increase the construction rate of non-centrosymmetric or even polar materials by using enantiomeric components. The combination of photoisomerization and piezoelectricity may support further exploration of optically-controlled smart devices for multi-channel information encryption and signal detection.

Summary: This article investigates the role of innate lymphoid cells (ILCs) in protective immunity. Using a mouse model specific to ILCs, researchers found that ILC2s have non-redundant functions during steady state and disease, and they interact with adaptive immune cells to organize the immune system.

Summary: The Fermi surface plays a crucial role in material properties. Fermi arcs can be signatures of unusual electronic states and can be obtained by breaking specific symmetries. In this study, experimental evidence is presented showing the emergence of hole- and electron-like Fermi arcs below the Neel temperature in an antiferromagnetic state. This magnetic splitting effect is unique as it creates bands with opposing curvature that change with temperature.

Summary: The potential nonlinear optical material of sulfamic acid (SA) with added europium (Eu3+) was successfully grown using the slow evaporation solution (SEST) and Sankaranarayanan-Ramasamy (SR) techniques. The crystal's structure and morphology were confirmed through single-crystal X-ray diffraction analysis. FTIR studies were used to identify functional groups and determine molecular vibrations. The grown crystals exhibited high transparency, moderate thermal stability, and excellent red light properties, making them suitable for optoelectronic and device applications.

Summary: This paper reviews the linear and non-linear dynamics of an optomechanical system consisting of a two-membrane etalon and a high-finesse Fabry-Perot cavity. This system has the potential to modify the single-photon optomechanical coupling and cool two mechanical oscillators simultaneously. It is a promising platform for realizing cavity optomechanics with multiple resonators. In the non-linear regime, an analytical approach based on slowly varying amplitude equations allows for a truthful detection of membrane displacements beyond the linear sensing limits imposed by the cavity linewidth. Additionally, the system exhibits a pre-synchronization regime.

Summary: The spontaneous crystallization method was used to synthesize two non-centrosymmetric scandium borate crystal materials with wide band gaps and good second harmonic generation (SHG) effects. First-principles calculations revealed that the arrangement of [B5O10](5-) groups and the distortion of ScO6 polyhedra were responsible for the SHG response. The materials may have potential applications in UV nonlinear optical devices.

Summary: This study investigates a new series of Janus 2D structures MM'XX' and finds that they exhibit high dynamical stability, suitable band gaps, strong light absorption in the visible light region, and high energy conversion efficiencies, making them promising candidates for photocatalytic water splitting. Additionally, the in-plane piezoelectric coefficients of these monolayers are comparable to common bulk materials, while the out-of-plane piezoelectric coefficients are higher than those of other Janus monolayers.

Summary: In this work, a theoretical study of magnetically-induced Pekar-Rashba spin splitting in antiferromagnetic monolayers of both layered and nonlayered crystals is presented. A detailed two-step procedure for determining the magnetic layer group of a given monolayer is outlined, and all magnetic layer groups are classified into seven spin splitting prototypes. Based on symmetry arguments, it is possible to determine whether spin splitting is allowed in a given monolayer, with the magnitude of the spin splitting determined through Density Functional Theory calculations if allowed. Illustrative examples using both layered (MnPS3) and nonlayered (MnO2) crystals are provided.
