Humans have changed planetary boundaries; the depletion of virgin minerals and accumulation of urban minerals are occurring. In contrast to geological resources, the scientific classification of anthropogenic resources remains unsolved. Clarifying where, when, how many, and how various urban minerals accumulate and can be extracted is crucial for fostering a circular economy material “closed loop”. To this end, we developed a structural and evidence-based quantifiable classification method to explore the availability (resource) and accessibility (reserve) of urban minerals. Using China’s electric and electronic equipment and automobile industries as a case study, our analysis indicates that the annual urban minerals “formation” in 2023 has reached 27 million tons. Among 42 target metals, eight were mineable, 26 were unmineable, and the remaining eight were swinging between mineable and unmineable across scenarios. Furthermore, we found that enhancing separation and recovery ratios for Fe, Al, Cu, and precious metals can further reduce reliance on natural sources for these minerals by 9%–15% and that optimizing recycling value thresholds for the other 37 metals (e.g., rare earth elements and light metals) can replace the need to mine 7%–42% of these virgin minerals, potentially raising present circularity of electrical and electronic equipment and automobiles from one-third to half. This study reveals the “availability–accessibility” gradient structure of urban minerals and its coupling across policy, technological, and economic dimensions, offering scientific support for building urban mineral databases, formulating urban mining policies, and promoting the implementation of urban mining.
人类已经改变了地球的边界;原生矿物的枯竭和城市矿物的积累正在发生。与地质资源相比,人为资源的科学分类问题尚未解决。明确在何处、何时、有多少以及如何积累和提取各种城市矿物,对于促进循环经济材料“闭环”至关重要。为此,我们开发了一种结构化的、基于证据的量化分类方法来探索城市矿产的可用性(资源)和可及性(储量)。以中国的电气电子设备和汽车行业为例,我们的分析表明,到2023年,每年城市矿产“形成”量将达到2700万吨。在42种目标金属中,8种是可开采的,26种是不可开采的,其余8种在可开采和不可开采之间摇摆。此外,我们发现,提高Fe, Al, Cu和贵金属的分离和回收率可以进一步减少对这些矿物的天然来源的9%-15%的依赖,优化其他37种金属(例如稀土元素和轻金属)的回收价值阈值可以取代开采这些原始矿物的7%-42%的需求,有可能将目前的电气和电子设备和汽车的循环率从三分之一提高到一半。研究揭示了城市矿产资源“可得性-可达性”梯度结构及其在政策、技术和经济三个维度上的耦合关系,为城市矿产资源数据库建设、城市矿业政策制定、城市矿业实施提供科学支撑。

Single-atom catalysts (SACs) challenge conventional multi-site catalysis by enabling oxidative processes like H2 and CO oxidation. However, we herein present that the completely isolated SACs are inactive, while spatially adjacent single-atom pairs (interatomic distance < 4 Å) work cooperatively as the true active sites. Rh atomic densities were precisely tuned between 0.1 wt%–17.5 wt% via graphene quantum dots confinement. Mathematical modeling quantifies the scaling of active pairs versus electrochemical performance, rationalizing activity dependence on atomic proximity. 18O isotope labeling and in situ synchrotron infrared spectroscopy analyses identified a new reaction mechanism, with water bifunctional dissociation enabled on sub-4 Å Rh pairs, and acts as the rate-determining step towards both CO and H2 oxidation. While H2O enters the COOR process as a reactant and enters the HOR process as a molecular catalyst. Our findings redefine bifunctional catalysis, merging single-atom precision with nanoparticle-like cooperativity for efficient energy conversion systems.
单原子催化剂(SACs)通过实现H2和CO氧化等氧化过程,挑战了传统的多位点催化。然而,我们在此发现,完全分离的SACs是无活性的,而空间相邻的单原子对(原子间距离18O同位素标记和原位同步红外光谱分析)发现了一种新的反应机制,在亚4 Å Rh对上实现了水双功能解离,并作为CO和H2氧化的速率决定步骤。而H2O作为反应物进入COOR过程,作为分子催化剂进入HOR过程。我们的发现重新定义了双功能催化,将单原子精度与纳米粒子的协同性结合起来,用于高效的能量转换系统。

Liquid Ga nanodroplet-templated heteroepitaxy of MAPbI3 for high-efficiency printable mesoscopic perovskite solar cells 液态Ga纳米微滴模板MAPbI3异质外延制备高效可印刷介观钙钛矿太阳能电池。

Precise control over microstructure and crystallinity of perovskite films is pivotal for achieving high-performance solar cells. However, realizing large-grained and preferentially oriented perovskite crystals remains particularly challenging in printable mesoscopic architectures. Herein, we present a liquid-metal-enabled heteroepitaxial strategy to regulate MAPbI3 crystallization on Ga2O3 surfaces derived from Ga nanodroplets. Structural modeling and atomic-resolution transmission electron microscope (TEM) analysis reveal an exceptional lattice match between the (1 1 0) planes of MAPbI3 and the exposed Ga2O3 facets, with an ultralow mismatch of merely 0.32%. This near-perfect lattice alignment drives the formation of orientation-controlled MAPbI3 crystals within the mesoporous scaffold. Moreover, the epitaxial interface establishes type-II band alignment that accelerates charge extraction while suppressing interfacial recombination. The resultant printable mesoscopic perovskite solar cells achieve a champion power conversion efficiency (PCE) of 20.2% (AM1.5G), representing a 16% enhancement over conventional non-epitaxial counterparts. Crucially, the devices demonstrate exceptional operational stability, retaining 97% of initial PCE after 3000 h of maximum power point tracking under harsh conditions (55 ± 5 °C, 85% RH).
精确控制钙钛矿薄膜的微观结构和结晶度是实现高性能太阳能电池的关键。然而,在可打印的介观结构中,实现大晶粒和优先取向的钙钛矿晶体仍然是特别具有挑战性的。在此,我们提出了一种液态金属异质外延策略来调节来自Ga纳米液滴的Ga2O3表面上的MAPbI3结晶。结构建模和原子分辨率透射电子显微镜(TEM)分析显示,MAPbI3的(110)面与暴露的Ga2O3面之间的晶格匹配异常,其失配率仅为0.32%。这种近乎完美的晶格排列驱动了介孔支架内取向控制的MAPbI3晶体的形成。此外,外延界面建立了ii型带对准,加速了电荷提取,同时抑制了界面复合。由此产生的可印刷介观钙钛矿太阳能电池的功率转换效率(PCE)达到20.2% (AM1.5G),比传统的非外延型太阳能电池提高了16%。至关重要的是,这些器件表现出卓越的运行稳定性,在恶劣条件下(55±5°C, 85% RH),在最大功率点跟踪3000小时后,保持了97%的初始PCE。

Human-machine intelligent interaction (HMII) technology, which is an advanced iteration of human–machine interaction technology, has garnered widespread attention owing to its significant achievements in healthcare and virtual reality research. Nonetheless, these fields often depend on elaborate multi-sensor integrations and face challenges in achieving precise control over robotic manipulation. Herein, a novel transistor-like iontronics pressure sensor based on an MXene/Bi 2D heterojunction is proposed. This transistor-like, flexible, all-solid-state, self-powered iontronics device exhibited a fast response time (66.59 ms), long lifetime (up to 50,000 cycles), and static/dynamic response with linear sensitivity. A deep-learning-assisted single-device HMII system was further constructed. Crucially, the system is adept at monitoring subtle skin deformations triggered by the median and ulnar nerves, efficient real-time decoding of sophisticated hand gestures (recognition accuracy of 95.83%), and precise control of robotic hands using tactile perception feedback. This approach addresses the inherent redundancy in multi-sensor devices used to decode motion across multiple finger joints, marking a significant step forward for iontronics in enhancing the perceptual interaction between humans and machines.
人机智能交互(HMII)技术作为人机交互技术的高级迭代,因其在医疗保健和虚拟现实研究领域取得的重大成就而受到广泛关注。尽管如此,这些领域往往依赖于复杂的多传感器集成,并且在实现对机器人操作的精确控制方面面临挑战。本文提出了一种基于MXene/Bi二维异质结的新型类晶体管离子电子压力传感器。这种类晶体管、柔性、全固态、自供电的电子器件具有快速响应时间(66.59 ms)、长寿命(高达50000次循环)和具有线性灵敏度的静态/动态响应。进一步构建了深度学习辅助的单设备人机交互系统。最关键的是,该系统擅长监测由正中神经和尺神经引发的细微皮肤变形,能够高效实时解码复杂手势(识别准确率达95.83%),并利用触觉感知反馈精确控制机械手。这种方法解决了用于解码跨多个手指关节运动的多传感器设备的固有冗余,标志着电子技术在增强人与机器之间的感知交互方面向前迈出了重要一步。
