Professor Yuyang Hou's research lab specializes in advanced energy storage materials and sustainable materials engineering, with a focus on rechargeable batteries, including lithium–carbon dioxide and aqueous rechargeable lithium batteries. The lab develops novel functional materials such as Mo₂C/carbon nanotube composites and three-dimensionally macroporous cathodes to enhance energy efficiency, cycle stability, and energy density. Additionally, the lab investigates structural materials, particularly ferritic stainless steels with dual stabilization, to improve solidification behavior and microstructural compactness. The integration of green building concepts with consumer behavior in fitness services reflects an emerging interdisciplinary interest in sustainable urban development.

The rechargeable Li–CO 2 battery is a novel and promising energy storage system with the capability of CO 2 capture due to the reversible reaction between lithium ions and carbon dioxide. Carbon materials as the cathode, however, limit both the cycling performance and the energy efficiency of the rechargeable Li–CO 2 battery, due to the insulating Li 2 CO 3 formed in the discharge process, which is difficult to decompose in the charge process. Here, a Mo 2 C/carbon nanotube composite material is
Our former research found that lithium metal coated with a gel polymer electrolyte and LISICON film can be stable in aqueous electrolytes to carry out lithium plating and dissolution, and is a good anode for high energy density aqueous rechargeable lithium batteries (ARLBs). Here we prepared three-dimensionally macroporous LiFePO4 and used it as the cathode to build another ARLB in 0.5 mol l−1 Li2SO4 aqueous solution. Its stable output voltage is 3.32 V with excellent cycling performance and goo
The effect of Nb on the as-cast structure and compactness degree of ferritic stainless steel (FSS) dual stabilized by Ti and Nb are investigated. In this study, the as-cast structure of experimental ingots were almost composed of equiaxed grains and Ti-Mg-Al-oxide enveloped by Ti(C,N) or (Ti,Nb)x(N,C)y, namely complex nucleus, was found in the interior of FSS grain. When Nb was added to FSS, the as-cast grain size became smaller and the grain boundary precipitates (BP) became smaller and more di
Green buildings play a pivotal role in advancing ecological civilization and promoting green, low-carbon development. Numerous studies have delved into the construction techniques, process attributes, economic benefits, risk management, and benefit assessments associated with green buildings. Concurrently, research on the profitability models, marketing strategies, and public purchasing intentions of commercial fitness clubs has also yielded extensive findings. Yet, there is a noticeable gap: li
