High brightness far-red light plays a crucial role in enhancing photosynthetic efficiency and crop yield in plant factories. Here, Cr³⁺-activated silicate ceramics with near-unity internal quantum efficiency and negligible thermal quenching were developed through full crystallization of glass precursors. Importantly, Ba²⁺ substitution for Ca²⁺ in Y₂CaAl₄SiO₁₂:Cr³⁺ strengthens the local crystal field, tuning the emission into a narrow far-red band well matched with phytochrome absorption. The optimized ceramics enable 27% wall-plug efficiency in far-red pc-LEDs and record 2.1 W output in laser-driven sources, highlighting their potential as robust all-inorganic color converters for high-power plant-growth lighting.

Facing the increased severely environmental challenges and energy shortages, the development of new green energy systems to replace the traditional fossil fuels has become more urgent for human being. Hydrogen (H₂) is regarded as the environmentally friendly and renewable energy resource for the future. Its unparalleled virtue lies in the fact that its combustion byproduct is exclusively water. Alkaline water electrolysis (AWE) technology is recognized as one of the most promising methods for hydrogen production, while its widespread adoption has been impeded by the high associated costs, its global market share remains negligible, at less than 4%. Reducing the cost of alkaline water electrolysis for the production of green hydrogen is a common challenge for countries around the world. The limited elemental abundance and high cost of noble metal electrocatalysts like Pt and RuO₂ constrain their large-scale application. Therefore, the development of bifunctional non-precious metal electrocatalysts with a high catalytic activity, low cost, and excellent stability is essential to significantly improve the energy efficiencies of AWE.

A study in Forest Ecosystems revealed that Continuous Cover Forestry (CCF) in Europe partly originated in a 17th-century practical agroforestry innovation, and not exclusively in a 19/20th-century academic debate as previously thought. The research into forestry history traced the development of CCF all the way from early agroforestry, through individual-based silviculture, and eventually to the later academic debate, offering historical insights for modern sustainable forest management.

A study in Forest Ecosystems reveals that two closely related evergreen oaks (Quercus aquifolioides and Quercus spinosa) in the Himalayan-Hengduan Mountains adapt to different climates through adjustments in leaf trait integration and modularity, with the high-altitude species having flexible traits for harsh conditions and the lowland one showing tightly coordinated traits for efficiency. It also notes the findings’ value for conservation and understanding species’ responses to climate change.

Inspired by oriented and Bouligand structures in natural organisms with remarkable strength and toughness, this study aims to construct biomimetic HA bioceramics with fine microstructures at nanoscale and microscale to enhance the mechanical properties. An innovative magnetic field-assisted 3D printer was developed to create oriented and Bouligand structural HA ceramics under weak magnetic field strengths (58 mT - 116 mT).

This article has developed an integrated multifunctional composite by combining SiCN ceramics, porous ceramics, and phase change materials via a vacuum impregnation process. The resulting composite achieves an impressive minimum reflection loss of -31.29 dB. Leveraging its phase change property, the PCM effectively buffers temperature fluctuations within the composite. When heated at 90℃ for 42 minutes, the composite maintains a significant temperature difference of 36.6℃ from the external thermal load—this unique thermal buffering capability ensures the material delivers stable thermal insulation and reliable infrared stealth performance. This innovative design offers valuable new insights for advancing the development of multifunctional electromagnetic wave-absorbing materials.

Wind and solar energy are central to China’s pursuit of carbon neutrality and energy transition. From a system-wide perspective, this study examines the future development of wind power, photovoltaic (PV), and concentrated solar power (CSP), covering forecasting methodologies, power system flexibility, energy storage integration, and cross-sector coupling. By 2060, the combined installed capacity of wind and solar is projected to reach 5,496–7,662 GW, accounting for more than 83% of the nation’s total capacity. Despite progress in technological maturity and cost reduction, challenges remain in terms of limited generation efficiency, high storage costs, insufficient grid flexibility, and policy coordination. This paper further proposes a sustainable development roadmap centered on wind–solar synergies.

To achieve carbon neutrality by 2060, China must address the complex challenge of decarbonizing key industrial sectors, including steel, cement, petrochemicals, and non-ferrous metals. This review presents a comprehensive evaluation of major decarbonization technologies across these core sectors, including energy efficiency, clean electrification, hydrogen alternatives, feedstock substitution, recycling, carbon removal, and digitalization. Staged projections highlight the central role of different technologies in achieving industrial decarbonization: energy efficiency improvement (EEI) and feedstock substitution and waste recycling (FSWR) technologies before 2035, the accelerated deployment of clean electricity and green hydrogen between 2035 and 2050, and carbon capture, utilization and storage (CCUS) from 2050 onward. The review further offers policy recommendations to support technological advancement, promote large-scale deployment, and integrate low-carbon solutions into industrial development pathways.

There are many examples of options to tackle various global challenges that have been implemented in ways that only consider the impact on the challenge they are meant to address. Because of this narrow way of thinking, we are missing out on potential synergies that would help us to deliver to multiple challenges simultaneously. Designing options from the outset to co-deliver to multiple challenges would improve efficiency and reduce total cost. It is vital that we progress beyond narrow ways of thinking, and to adopt a “nexus” approach to tackling global challenges.

Scientists have developed a pioneering framework that translates human brain activity into editable visual imagery, opening up new possibilities for creative design and human–computer interaction. Named DreamConnect, the system employs a dual-stream diffusion model to directly interpret functional magnetic resonance imaging (fMRI) signals and refine them with natural language instructions. By progressively aligning brain activity with user-directed prompts, the method allows for manipulation of imagined scenes—such as transforming a mental picture of a lake into a vivid sunset. This breakthrough demonstrates the potential of brain-to-image technologies to actively shape human “dreams,” suggesting future applications in design, therapy, and communication.
