Summary: A new strategy is presented to reconfigure self-recordable photonic crystal (PC) patterns by printing local patterns into chameleon-inspired PC papers using phase change material (PCM) as ink and erasing the patterns in ethanol. This method allows for efficient and repeated reconfiguration of multicolor and high-resolution patterns, and also demonstrates the mechanochromic characteristics of photonic patterns based on the PC paper and PCM combinations.

Summary: This study synthesizes a photonic material of topological Floquet time crystals and experimentally observes its indicative period-2T beating. A single-particle picture is explicitly reconstructed of discrete time-crystalline phase and is revealed using an appropriately-designed photonic Floquet simulator the rigid period-doubling as a signature of the breakage of the discrete time-translational symmetry. The photonic Floquet time crystal is derived from a newly defined single-particle topological phase that can be extensively accessed by many pertinent nonequilibrium and periodically-driven platforms.

Summary: Surface deposition of FeOx nanoclusters on TiO2 photonic crystals was investigated to explore the interplay of slow-photon amplification, visible light absorption, and charge separation in FeOx-TiO2 photocatalytic films. The study found that low amounts of FeOx nanoclusters improved photocatalytic performance under visible light, but higher loading resulted in performance deterioration, particularly under UV-Vis light.

Summary: Eliminating benzene and formaldehyde pollution is crucial in today's society of colorful home decoration. This study demonstrates the possibility and advantages of using vividly colorful amorphous photonic crystals (APCs) as catalytic pigments. By introducing oxygen vacancies through thermal vacuum de-oxygenation, SiO2@TiO2-x APCs with angle-independent structural colors and enhanced photocatalytic performance were successfully synthesized. The presence of oxygen vacancies in TiO2-x promotes electron activation and synergistically improves the degradation of formaldehyde, effectively protecting the beautiful living environment of human beings.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

Summary: In this study, a new spin-gapless semiconductor material CoFeMnSn is reported, and its stable structure and spin-polarized band structure are determined through experimental realization and theoretical calculations. The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
