Researchers from Southeast University have developed a novel amplifying and filtering reconfigurable intelligent surface (AF-RIS) that enhances wireless communication for 6G networks. The AF-RIS achieves significant signal amplification, frequency selectivity, and beam-steering capabilities while reducing hardware costs and power consumption. This innovation could revolutionize wireless relay systems in next-generation networks.

Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G millimeter-wave communication. The array integrates four independent beamforming systems on a single printed circuit board, supporting concurrent operations at 28 GHz and 38 GHz. It features scalable architecture, broad bandwidth, and high spectral efficiency, making it ideal for future high-speed wireless applications.

Recently, micro/nanosatellites have become a significant trend in space with the rapid development of space technology, microelectromechanical systems, and commercial off-the-shelf components. However, most traditional micro/nanosatellites have poor reliability and real-time performance. The implementation of a real-time operating system (RTOS) can effectively prevent system crashes due to untimely responses, thereby enhancing the real-time performance and reliability of the micro/nanosatellite attitude determination system. The Dalian-1 Lianli satellite, a 17-kg 12U high-resolution remote sensing CubeSat, was developed to validate a series of innovative technologies, including submeter high-resolution remote sensing imaging, the high-reliability OpenHarmony real-time operating system (RTOS), and the nontoxic hydroxylamine nitrate propulsion system. The satellite first uses the free, high-reliability OpenHarmony RTOS in the world. Launched on 2023 May 10, aboard the Tianzhou-VI cargo spacecraft, the satellite was successfully deployed into orbit on 2024 January 18, following 253 d of in-orbit storage at the China Space Station.

The positioning, navigation, and timing (PNT) information is fundamental to modern information systems. Over the years, people have invented many navigation systems to get PNT information, whereas each single navigation system has its flaws. As far as radio navigation is concerned, besides global navigation satellite systems (GNSS), exploiting non-navigation signals of opportunity for navigation under complex environments has attracted more and more interest in recent years. Satellite signals of opportunity positioning (SSOOP) attempts to work out a navigation solution with many non-GNSS satellite signals, such the many low-earth-orbit direct-to-cell and broadband satellite communications signals, when GNSS signals are not available. It is promising in addressing GNSS vulnerability by using an overwhelming quantity of satellites with diverse signal formats, multiple radio bands, and global availability. However, existing work on SSOOP is still quite preliminary. No work on identifying the passing satellite has been done when a receiver powers on without a rough guess on its location.

An Osaka Metropolitan University-led research team investigated Escherichia albertii, what is known about this bacterium, and directions of future research to fill the knowledge gap. 

High-temperature stealth is vital for enhancing the concealment, survivability, and longevity of critical assets. However, achieving stealth across multiple infrared bands—particularly in the short-wave infrared (SWIR) band—along with microwave stealth and efficient thermal management at high temperatures, remains a significant challenge. Here, we propose a strategy that integrates an IR-selective emitter (Mo/Si multilayer films) and a microwave metasurface (TiB₂–Al₂O₃–TiB₂) to enable multi-infrared band stealth, encompassing mid-wave infrared (MWIR), long-wave infrared (LWIR), and SWIR bands, and microwave (X-band) stealth at 700 °C, with simultaneous radiative cooling in non-atmospheric window (5–8 μm). At 700 °C, the device exhibits low emissivity of 0.38/0.44/0.60 in the MWIR/LWIR/SWIR bands, reflection loss below − 3 dB in the X-band (9.6–12 GHz), and high emissivity of 0.82 in 5–8 μm range—corresponding to a cooling power of 9.57 kW m⁻². Moreover, under an input power of 17.3 kW m⁻²—equivalent to the aerodynamic heating at Mach 2.2—the device demonstrates a temperature reduction of 72.4 °C compared to a conventional low-emissivity molybdenum surface at high temperatures. This work provides comprehensive guidance on high-temperature stealth design, with far-reaching implications for multispectral information processing and thermal management in extreme high-temperature environments.
