A new expert commentary in ENGINEERING Energy （formerly Frontiers in Energy）underscores a revolutionary "self-supplied hydrogen" strategy that achieves 99% selectivity in upcycling polyethylene into high-value fuel without external hydrogen sources.

With the upcoming Milano Cortina 2026 Winter Paralympic Games, national and international media attention is once again turning to Paralympic sport. But how is it presented to the public? The study “It should just be about sport!”: exploring Italian athletes' perspectives in paralympic media coverage – conducted by Athanasios Pappous and Pablo Iniesta at the University of Bologna’s Department for Life Quality Studies and published in the international journal Frontiers in Sports and Active Living – collected the direct testimonies of 17 high-level Italian Paralympic athletes to investigate how they perceive their representation in the media.

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.

The regulation of electron transfer is crucial for enhancing the catalytic efficiency of catalysts. Currently, CO selective reduction of NO_x (CO-SCR) catalysts with surface synergistic oxygen vacancies (SSOVs) or alloyed components exhibit superior performance but face challenges of reduced activity and stability in oxygen-rich environments. Here, we demonstrate a strategy that combines PtCo alloys (0.01% Pt; 0.04% Co) with SSOVs in cerium zirconium oxide solid solution to interactively modulate the electronic structure, resulting in a significant enhancement of both the activity and stability of the catalyst under oxygen-rich conditions. This catalyst achieved over 85% NO conversion at 300 ℃ and 5% O₂, while maintaining approximately 100% N₂ selectivity during 20 h-stability testing, surpassing the performance of the monometallic catalysts. This enhancement arises from the synergistic electronic effects of alloying and SSOVs, which generate negatively charged Pt that facilitates NO adsorption and dissociation, while concurrently producing electron-deficient SSOVs that weaken O₂ chemisorption and promote the formation of moderate reactive oxygen species. Moreover, the preferential adsorption of CO on Co sites alleviates competitive adsorption.
