Cement stands as a dominant contributor to global energy consumption and carbon emissions in the construction industry. With the upgrading of infrastructure and the improvement of building standards, traditional cement fails to reconcile ecological responsibility with advanced functional performance. By incorporating tailored fillers into cement matrices, the resulting composites achieve enhanced thermoelectric (TE) conversion capabilities. These materials can harness solar radiation from building envelopes and recover waste heat from indoor thermal gradients, facilitating bidirectional energy conversion. This review offers a comprehensive and timely overview of cement-based thermoelectric materials (CTEMs), integrating material design, device fabrication, and diverse applications into a holistic perspective. It summarizes recent advancements in TE performance enhancement, encompassing fillers optimization and matrices innovation. Additionally, the review consolidates fabrication strategies and performance evaluations of cement-based thermoelectric devices (CTEDs), providing detailed discussions on their roles in monitoring and protection, energy harvesting, and smart building. We also address sustainability, durability, and lifecycle considerations of CTEMs, which are essential for real-world deployment. Finally, we outline future research directions in materials design, device engineering, and scalable manufacturing to foster the practical application of CTEMs in sustainable and intelligent infrastructure.

Aqueous alkali metal-ion batteries (AAMIBs) have been recognized as emerging electrochemical energy storage technologies for grid-scale applications owning to their intrinsic safety, cost-effectiveness, and environmental sustainability. However, the practical application of AAMIBs is still severely constrained by the tendency of aqueous electrolytes to freeze at low temperatures and decompose at high temperatures, limiting their operational temperature range. Considering the urgent need for energy systems with higher adaptability and resilience at various application scenarios, designing novel electrolytes via structure modulation has increasingly emerged as a feasible and economical strategy for the performance optimization of wide-temperature AAMIBs. In this review, the latest advancement of wide-temperature electrolytes for AAMIBs is systematically and comprehensively summarized. Specifically, the key challenges, failure mechanisms, correlations between hydrogen bond behaviors and physicochemical properties, and thermodynamic and kinetic interpretations in aqueous electrolytes are discussed firstly. Additionally, we offer forward-looking insights and innovative design principles for developing aqueous electrolytes capable of operating across a broad temperature range. This review is expected to provide some guidance and reference for the rational design and regulation of wide-temperature electrolytes for AAMIBs and promote their future development.

While desalination is a key solution for global freshwater scarcity, its implementation faces environmental challenges due to concentrated brine byproducts mainly disposed of via coastal discharge systems. Solar interfacial evaporation offers sustainable management potential, yet inevitable salt nucleation at evaporation interfaces degrades photothermal conversion and operational stability via light scattering and pathway blockage. Inspired by the mangrove leaf, we propose a photothermal 3D polydopamine and polypyrrole polymerized spacer fabric (PPSF)-based upward hanging model evaporation configuration with a reverse water feeding mechanism. This design enables zero-liquid-discharge (ZLD) desalination through phase-separation crystallization. The interconnected porous architecture and the rough surface of the PPSF enable superior water transport, achieving excellent solar-absorbing efficiency of 97.8%. By adjusting the tilt angle (θ), the evaporator separates the evaporation and salt crystallization zones via controlled capillary-driven brine transport, minimizing heat dissipation from brine discharge. At an optimal tilt angle of 52°, the evaporator reaches an evaporation rate of 2.81 kg m-2 h-1 with minimal heat loss (0.366 W) under 1-sun illumination while treating a 7 wt% waste brine solution. Furthermore, it sustains an evaporation rate of 2.71 kg m-2 h-1 over 72 h while ensuring efficient salt recovery. These results highlight a scalable, energy-efficient approach for sustainable ZLD desalination.
虽然海水淡化是全球淡水短缺的关键解决方案，但由于集中的盐水副产品主要通过沿海排放系统处理，其实施面临环境挑战。太阳界面蒸发提供了可持续的管理潜力，但蒸发界面上不可避免的盐成核会通过光散射和路径阻塞降低光热转换和操作稳定性。受红树林叶片的启发，我们提出了一种基于光热3D聚多巴胺和聚吡咯聚合空间织物（PPSF）的上吊模型蒸发配置，具有反向给水机制。该设计通过相分离结晶实现了零液体排放（ZLD）海水淡化。相互连接的多孔结构和粗糙的表面使PPSF具有优越的水输送能力，实现了97.8%的优异太阳能吸收效率。通过调节倾斜角度（θ），蒸发器通过控制毛细管驱动的盐水输送将蒸发区和盐结晶区分开，最大限度地减少了盐水排放的散热。在最佳倾角为52°时，蒸发器在1个太阳光照下的蒸发速率为2.81 kg m-2 h-1，热损失最小（0.366 W），同时处理7 wt%的废盐水溶液。此外，它在72 h内保持2.71 kg m-2 h-1的蒸发速率，同时确保有效的盐回收。这些结果突出了可持续ZLD脱盐的可扩展、节能方法。

MXene-based smart contact lenses demonstrate a cutting-edge advancement in wearable ophthalmic technology, combining real-time biosensing, therapeutic capabilities, and user comfort in a single platform. These devices take the advantage of the exceptional electrical conductivity, mechanical flexibility, and biocompatibility of two-dimensional MXenes to enable noninvasive, tear-based monitoring of key physiological markers such as intraocular pressure and glucose levels. Recent developments focus on the integration of transparent MXene films into the conventional lens materials, allowing multifunctional performance including photothermal therapy, antimicrobial and anti-inflammation protection, and dehydration resistance. These innovations offer promising strategies for ocular disease management and eye protection. In addition to their multifunctionality, improvements in MXene synthesis and device engineering have enhanced the stability, transparency, and wearability of these lenses. Despite these advances, challenges remain in long-term biostability, scalable production, and integration with wireless communication systems.

Cellulose frameworks have emerged as promising materials for light management due to their exceptional light-scattering capabilities and sustainable nature. Conventional biomass-derived cellulose frameworks face a fundamental trade-off between haze and transparency, coupled with impractical thicknesses (≥ 1 mm). Inspired by squid's skin-peeling mechanism, this work develops a peroxyformic acid (HCOOOH)-enabled precision peeling strategy to isolate intact 10-µm-thick bamboo green (BG) frameworks-100 × thinner than wood-based counterparts while achieving an unprecedented optical performance (88% haze with 80% transparency). This performance surpasses delignified biomass (transparency < 40% at 1 mm) and matches engineered cellulose composites, yet requires no energy-intensive nanofibrillation. The preserved native cellulose I crystalline structure (64.76% crystallinity) and wax-coated uniaxial fibril alignment (Hermans factor: 0.23) contribute to high mechanical strength (903 MPa modulus) and broadband light scattering. As a light-management layer in polycrystalline silicon solar cells, the BG framework boosts photoelectric conversion efficiency by 0.41% absolute (18.74% → 19.15%), outperforming synthetic anti-reflective coatings. The work establishes a scalable, waste-to-wealth route for optical-grade cellulose materials in next-generation optoelectronics.
