As the installed capacity of renewable energy such as wind and solar power continues to increase, energy storage technology is becoming increasingly crucial. It could effectively balance power demand and supply, enhance allocation flexibility, and improve power quality. Among various energy storage technologies, liquid CO₂ energy storage (LCES) stands out as one of the most promising options due to its advantages such as high round-trip efficiency (RTE), high energy storage density (ESD), safety, stability, and longevity. Within the system, the cold and heat storage units play a critical role in determining the overall performance of the system and are particularly important among its various components. In this paper, a novel LCES system is proposed and the heat transfer characteristics are analyzed in detail. Then, the impact of key parameters on the liquefaction ratio and RTE is discussed. The results indicate that the RTE, ESD, and exergy efficiency of the system are 56.12%, 29.46 kWh/m³, and 93.73% under specified design conditions, respectively. During the gas–liquid phase change process of carbon dioxide or when it is in a supercritical state, the related heat transfer processes become more complex, leading to increased energy loss. The analysis of key parameters of the Linde-Hampson liquefaction unit reveals that as the liquefaction temperature decreases, both the liquefaction ratio and RTE increase. While the liquefaction pressure has a minimal impact on the liquefaction ratio, it significantly affects RTE, with an optimal liquefaction pressure identified.

Electromagnetic radiation interferes with the operation of electronic devices and poses a threat to human health, while traditional microwave absorbing materials are difficult to meet the core requirements of being "thin, light, wide and strong". Inspired by the structure of coral reefs, a Chinese research team has designed a ZnNiCo-LDH/MXene composite material. Through biomimetic porous structures and high-density heterojunction engineering, it achieves an electromagnetic reflection loss of -49.6 dB at a thickness of 1.35 mm and a radar cross-section suppression of -39.57 dB · m². This breakthrough provides a brand-new approach to solving the problems of electromagnetic pollution and military stealth technology.

Thermal stability and environmental sustainability are paramount to the practical deployment of perovskite solar cells (PSCs), which are designed to harness solar energy through high-efficiency and low-cost photovoltaic technology. Pseudo-halide thiocyanate anions (SCN⁻), employed as a crystallization modulator, have emerged as an ideal candidate for tailoring the formation of high-quality mixed-cation perovskite films, paving the way for a new era of efficient and high-quality PSCs.

Researchers at Graz University of Technology are using virtual reality and large language models to support people with autism spectrum disorder in training social skills. The system is intended to make treatment options more widely accessible.

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching sensors to the inspection target. By enabling remote ultrasonic excitation and reception, the technology is expected to help prevent industrial accidents and eliminate inspection blind spots in high-risk industrial facilities where direct sensor installation has been challenging due to heat, toxic gases, or other hazardous environmental conditions.
