Summary: The study investigates the shear flow of active filaments in a thin channel for both extensile and contractile fibers, analyzing the stability properties under different parameters. Extensile fibers transition to unstable frequencies at a positive threshold value of the activity parameter, while contractile fibers exhibit complex behavior at low absolute values of the activity number. Flow behaviors of contractile fibers are also highly sensitive to the Reynolds number compared to extensile fibers.

Summary: Building photonic crystals on flexible textiles can create structural color fabrics, but there are challenges with fabric properties, stability, and application scenarios. This study successfully immobilized polystyrene photonic crystals on cotton fabric, providing bright colors and high mechanical stability. The fabric could also be used for adhesive tapes with good adhesive properties to different materials.

Summary: By studying quasi two-dimensional, monodisperse systems of active Brownian particles, the researchers developed an analytical method for predicting dense phase structures and found that formulating macroscopic pressure as interparticle pressure can lead to consistent pressure predictions. The research also showed that both interface width and surface tension are intrinsic characteristics of the system, and excluding the body force induced by activity results in linearly dependent surface tension values.

Summary: We investigated a family of free-standing quasi-two-dimensional silicon structures based on a planar square bilayer with adatom decorations. The geometry significantly contributes to the stability of structures, with some squared bilayers energetically more stable than honeycomb bilayers. The most interesting phases characterized were all found to be metallic, and we suggest the [100] surface of ZrO2 as the most suitable substrate for the synthesis of these two-dimensional phases.

Summary: This study investigates the factors contributing to the formation of polymorphs, hydrates, solvates, and solvate hydrates in three hydantoin-based active pharmaceutical ingredients-nitrofurantoin, furazidin, and dantrolene. Crystallographic and computational analysis of the crystal structures of these compounds reveals differences in their hydrogen bonding patterns and packing features, which correlate with their propensity to form solvates and solvate hydrates. The stability of the hydrate phases also plays a role in the differences observed.

Summary: Understanding how order emerges in active matter can help control microscopic objects on a macroscopic scale. This study demonstrates the control of passive microscopic particles in the presence of motile algae and boundary-induced accumulation of microswimmers, and the experimental realization of de-mixing of an active-passive suspension, providing a way to manipulate colloidal objects through controlled activity fields.

Summary: This study investigates the mechanical and electronic properties of bilayer borophene using first-principles calculations. The results reveal that the interlayer interactions in bilayer borophene involve both van der Waals and covalent bonding. The study also shows that the substrate and stacking method significantly affect the stability and mechanical properties of bilayer borophene.

Summary: This study demonstrates the achievement of a complete photonic band gap in cubic blue phase by doping with high refractive index nanoparticles, resulting in increased PBG width and self-collimation and negative refraction of light. This finding is of great significance for the control of light propagation.

Summary: Non-fullerene electron acceptors (NFAs) have gained significant attention in the organic solar cells (OSCs) field, showing remarkable development but facing stability challenges. This review highlights recent advances in understanding the stability of NFAs and their corresponding OSCs, focusing on chemical-, photon-, and thermal-induced degradations and approaches to enhance stability, with a vision of achieving over 20 years operational lifetime in real world applications.

Summary: In this paper, morphodynamic equations governing the behavior of active nematic fluids on deformable curved surfaces are constructed in the large deformation limit. Objective rates are formulated to account for normal deformations while ensuring that tangential flows are Eulerian, and the surface derivative is used in the nematic free energy to couple local order to out-of-plane bending of the surface. Several illustrative instabilities are characterized by focusing on surface geometry and its dynamical interplay with hydrodynamics.

Summary: We describe a mixed organic cationic hybrid nitrate, [C(NH2)2NHNO2][C(NH2)3](NO3)2 (1), which was synthesized by combining three different planar groups: [(C(NH2)2NHNO2]+, C(NH2)3+, and NO3-. First-principles calculations demonstrate that the [(C(NH2)2NHNO2]+ group is an excellent cationic nonlinear-optical (NLO)-active unit. The compound exhibits a moderate second-harmonic-generation (SHG) response (1.5 x KDP), a wide band gap (3.58 eV), and a suitable birefringence of 0.071 at 550 nm. Theoretical calculations indicate that the synergy effect between the [(C(NH2)2NHNO2]+ and C(NH2)3+ groups dominates the SHG process.

Summary: We study the behavior of quasi-2D gels comprised of a colloidal network doped with light-activated Janus particles. The gel ages slowly before the activation, and during the activation, the mobility of passive particles shows a scale-dependent response while the colloidal network remains connected. After activation, the gel retains its structure and becomes a softer gel with frozen dynamics and more space for thermal fluctuations. These conclusions remain valid long after the activity period.

Summary: This study investigated the active constituents in cabbage that interact with thyroid peroxidase (TPO) and their stability under cooking temperatures. The compound gamma-Terpinene was found to have the highest binding free energy, but it was susceptible to degradation at cooking temperature. Therefore, consuming cooked cabbage may be more beneficial for maintaining normal thyroid function.
