Summary: Image steganography based on intelligent devices is an effective way to transfer secret information safely and quickly. Optical image steganography, however, has received less attention compared to digital steganography due to the limitations in high-resolution optical imaging technology. Optical metasurfaces, made up of ultrathin subwavelength meta-atoms, are considered as competitive candidates for next-generation miniaturized devices. In this study, a strategy using multiplex imaging metasurfaces composed of single nanorods is proposed to achieve optical image steganography.

Summary: Based on the Jones matrix, independent control of both amplitude and phase of light has been achieved by combining meta-atoms into a metasurface supercell. However, the inherent limitation of a planar achiral structure restricts the maximum number of independent elements in one Jones matrix to three, limiting the amplitude and phase control. To overcome this limitation, this study proposes incorporating more Jones matrices corresponding to different angles of incidence to increase the degrees of freedom for control. By realizing four- or even eight-channel amplitude and phase control, the generation of multiple structured light patterns is demonstrated numerically, showcasing the potential impact on optical applications such as communications and encryption.

Summary: Metasurfaces consisting of planar subwavelength structures are used in emerging technologies for their small size and compatibility with nanofabrication techniques. However, the reduced dimensionality of metasurfaces poses challenges for adapting methods used in conventional optics. This work demonstrates the experimental realization of phase-coded multiplexing using a metasurface, and also achieves code-based all-optical routing. These findings have important implications for integrated optics and photonic data processing.

It enables single-channel/multichannel/color nanoprinting in a holography way, with unique characteristics such as incoherent light illumination, arbitrary brightness modulation, polarization insensitivity, and zero-dispersion. The holographic interference pattern generation further enhances the safety of information delivery.

Summary: The research team has developed an electrochemically inert and catalytic sp2c-COF separator to stabilize Li plating/stripping and accommodate high mass loadings of cathode in future high energy-density rechargeable batteries with Li metal anodes (LMAs). The nano-pores of sp2c-COF enable homogeneous Li+ flux and its electrochemical inertness prevents side reactions. The cyano-groups on sp2c-COF are critical for generating an inorganic-rich solid electrolyte interphase. Li symmetrical cells demonstrate excellent Li plating/stripping behaviors, and full batteries assembled with LiCoO2 and LiNi0.8Co0.1Mn0.1O2 cathodes show impressive areal capacities. This work provides an important strategy for the stabilization of LMA in rechargeable batteries.

Summary: This study used CFD to investigate turbulent flow heat transfer in a high-speed turbine rotor shaft cooling passage using supercritical CO2 as the coolant. The study examined coolant temperature, heat transfer coefficient, convection and frictional heat transfer, as well as the effects of clearance, mass flow rate, shaft rotational speed, and shaft temperature. The results showed that coolant temperature and heat transfer coefficient were not affected by radial clearance, while mass flow rate had a significant effect on coolant temperature. The study also found that convection heat transfer was significantly higher than frictional heat transfer, indicating the dominance of convection heat transfer in achieving effective cooling using supercritical CO2 fluid in the annulus passage. There was some disparity between the predicted heat transfer quantity using correlation and the CFD results.

Summary: This study aimed to investigate the global, regional, and national burden and temporal trends in MS incidence, deaths, and DALYs from 1990 to 2019. The results indicated that the global cases of incidence, deaths, and DALYs of MS have all increased, whereas age-standardized rates have declined. High SDI regions such as European countries have a substantial burden of MS. Age, period, and cohort effects were found to be significant factors in MS burden.

Summary: In this study, an eco-friendly and highly efficient biohybrid photocatalyst, carbonized rape pollen confined Cu2O nanoparticles (Cu2O/BC), was fabricated for the photodegradation of tetracycline under visible-light illumination. The Cu2O/BC exhibited excellent photocatalytic activity, with a degradation rate roughly 6.0 and 3.2 times higher than BC and Cu2O, respectively. The enhanced performance was attributed to the construction of a heterojunction, promoting the effective separation of photogenerated carriers, and the three-dimensional hollow BC providing structural stability for Cu2O. This work provides crucial insights into the utilization of nature-based biological materials in efficient antibiotic removal and environmental remediation.

Summary: This study aimed to assess the global burden and economic inequalities in the distribution of blindness and vision loss between 1990 and 2019. The results showed that countries with middle and low-middle socio-demographic index (SDI) were the most successful in decreasing the burden of blindness and vision loss. However, a high level of cross-national health inequality persisted over the past three decades. More attention must be paid to eliminating avoidable blindness and vision loss in low-income and middle-income countries.

Summary: Traditional holographic encryption methods based on the combination of gratings and liquid crystals (LCs) cannot provide full security due to the lack of strict requirements for decoding methods. In this paper, a simple but effective encryption method is proposed, and a four-in-one hologram based on photopatterned LCs is designed. The most important encrypted image can only be displayed when the four LC holograms in the same group are spliced into a whole according to the designed order. Our encryption scheme has the advantages of simple design, high security, and low crosstalk, with great potential in the fields of information hiding and image encryption.
