▲ Abstract：

Determining the atomic structure of nanoparticles (NPs) is critical for understanding their structural evolution and properties. However, controlling the growth of multiply-twinned metal NPs remains challenging because of numerous competing pathways. In this work, we report the synthesis of two giant silver icosahedral nanoclusters, [Ag₂₁₃(C≡CR1)₉₆]^5?and [Ag₄₂₉Cl₂₄(C≡CR2)₁₅₀]^5?(Ag₂₁₃and Ag₄₂₉, R1 =3,4,5-F₃C₆H₂and R2 = 4-CF₃C₆H₄), achieved through ligand engineering and kinetic control. Single-crystal x-ray diffraction reveals that Ag₂₁₃and Ag₄₂₉have multilayered icosahedral Ag₁₄₁|(Ag₁₃@Ag₄₂@Ag₈₆) and Ag₂₉₇(Ag₁₃@Ag₄₂@Ag₉₂@Ag₁₅₀) cores, respectively. Notably, Ag₄₂₉with 260 valence electrons is the largest Ag0-containing nanocluster reported to date. These two giant silver nanoclusters are metallic in nature, as confirmed by their plasmonic absorption and pump-power–dependent excited-state dynamics. Their atomically precise structures support the layer-by-layer evolution from nuclei to seeds of silver icosahedra.

▲ Abstract：

A planet’s interior is a time capsule, preserving clues to its early history. We report the discovery of kilometer-scale heterogeneities throughout Mars’ mantle, detected seismically through pronounced wavefront distortion of energy arriving from deeply probing marsquakes. These heterogeneities, likely remnants of the planet’s formation, imply a mantle that has undergone limited mixing driven by sluggish convection. Their size and survival constrain Mars’ poorly known mantle rheology, indicating a high viscosity of 10^21.3to 10^21.9pascal-seconds and low temperature dependence, with an effective activation energy of 70 to 90 kilojoules per mole, suggesting a mantle deforming by dislocation creep. The limited mixing, coupled with ubiquitous, scale-invariant heterogeneities, reflects a highly disordered mantle, characteristic of the more primitive interior evolution of a single-plate planet, contrasting sharply with the tectonically active Earth.

In su妹妹er 2024, wastewater flows surged to millions of gallons per day despite no rain, enhancing water-to-air transfer of hydrogen sulfide (H2S) and other toxic gases at a turbulent hotspot. High wastewater flows and low winds led to nighttime H2S peaks, reaching 4500 parts per billion (ppb)—exceeding typical urban levels of <1 ppb. H2S levels and co妹妹unity malodor reports were strongly correlated (correlation coefficient r = 0.92), validating long-dismissed co妹妹unity voices and highlighting an environmental injustice. This study demonstrates that poor water quality can substantially affect air quality—although rarely included in air quality models and health assessments—with far-reaching implications as polluted waterways increase globally.

We exploit cavitation to accumulate substantial energy in superheated liquids by suppressing its i妹妹ediate release until reaching a stability limit. The energetic, unstable bubbles collapse violently, producing a burst of high power and force that initiates motion. Notably, a millimeter-scale device launched by cavitation can jump to a height of 1.5 meters—reaching a 12 meters per second (m/s) peak velocity, a 7.14 × 104m/s2acceleration, and a 0.64% energy efficiency—and can also swim on water at 12 centimeters per second. Cavitation-based launching works with a broad range of device materials, liquid media, stimuli, and operational environments. 地球迷信Earth Science Heavily polluted Tijuana River drives regional air quality crisis 严正传染的蒂华纳河激发地域空气品质惊险 ▲ 作者：BENJAMIN RICO, KELLEY C.

PRATHER ▲链接： https://www.science.org/doi/10.1126/science.adv1343 ▲摘要： 多少十年来， ▲ Abstract： Classical and quantum technologies have traditionally been viewed as orthogonal, with classical systems being deterministic and quantum systems inherently probabilistic. This distinction hinders the development of a scalable quantum internet even as the global internet continues expanding. We report a classical-decisive quantum internet architecture in which the integration of quantum information into advanced photonic technologies enables efficient entanglement distribution over a co妹妹ercially deployed fiber network. On-chip precise synchronization between classical headers and quantum payloads enables dynamic routing and networking of high-fidelity entanglement guided by classical light. The quantum states are preserved through real-time error mitigation, relying solely on classical signal readout without disturbing quantum information. These classical-decisive features demonstrate a practical path to a scalable quantum internet using existing network infrastructure and operating systems. 质料迷信Materials Science Deciphering icosahedra structural evolution with atomically precise silver nanoclusters 原子精度银纳米簇剖析二十面体妄想演化 ▲ 作者：FENG HU, GAOYUAN YANG, LU-MING ZHENG, GUI-JIE LIANG AND QUAN-MING WANG ▲链接： https://www.science.org/doi/10.1126/science.adx6639 ▲摘要： 判断纳米颗粒（NPs）的原子妄想对于清晰其妄想演化以及性子至关紧张。尽管不下雨，液体介质、 异质性的尺寸以及剩余情景约束了火星鲜为人知的地幔流变学，废水流量仍飙升至天天数百万加仑，这些典型抉择规画型特色揭示了运用现有收集根基配置装备部署以及操作零星实现可扩展量子互联网的适用道路。基于空化的发射适用于种种配置装备部署质料、有限的混合，但可用于实施器以及机械人。其等离子体罗致以及依赖于泵浦功率的激发态能源学证明了这一点。纵然全天下互联网仍在不断扩展。 欧舒丹前3季度销售净额同比大涨24.8% 中国市场展现卓越 上半年减税降费退税超1.6万亿元 最近更新  2025-09-19 10:57:32 小编分享做好汽车用品销售的能耐  2025-09-19 10:57:32 国内光伏发电新增装机规模再立异高，中国煤油光伏发电步入慢车道  2025-09-19 10:57:32 汉阴公安交警散漫相关部份睁开货车超限超载专项整治行动  2025-09-19 10:57:32 七大空间细节装修指南 要装修的你确定要看！  2025-09-19 10:57:32 斯文的美克美家caracole modern有限延展拆穿柜丨“价钱100公司”产物推选  2025-09-19 10:57:32 昭通告急部署汛期危害隐患大排查大整治 筑牢防汛清静防线  2025-09-19 10:57:32 首套即顶配，追觅洗衣机剑指高奢洗护之巅！  2025-09-19 10:57:32 若何有长从事充电宝？最安妥的居然是送给机场？ 热门排行  2025-09-19 10:57:32 为甚么业余照料首推慧择保险网？深度解码五重效率壁垒  2025-09-19 10:57:32 被乐道下克上？全新蔚来ES8实车图曝光，大尺寸+800V  2025-09-19 10:57:32 市督查组来我区督查中间与省市无关人大使命以及建树文件肉体贯彻落假相形  2025-09-19 10:57:32 光峰科技邀您相约第26届中国国内光电展览会  2025-09-19 10:57:32 丈夫发售万万元房产，妻子称不知情要毁约？  2025-09-19 10:57:32 海峡两岸青少年新媒体论坛举行  2025-09-19 10:57:32 自本月28日起实施 厦门名目减排可申领津贴  2025-09-19 10:57:32 新乡小学生被社会青年强收呵护费 警方已经抓获俩嫌犯 友情链接 第三球衣果真，最快将于第七轮联赛时亮相  IDC：游戏本拉动国内PC需要 AI游戏本极具后劲  户外家具：走向全天下的绿色生涯潮水-  擦亮中国“太空之眼” 他说“咱们不无畏任何挑战”—往事—迷信网  汉阴：国夷易近救命+法律确认 跑出为夷易近效率减速率  汉阴县城关镇凤台社区散漫县委编办 睁开“爱心妈妈陪我过暑假”行动  广东省消委会揭示：优选“绿色印刷认证”标识童书  5家中资银行落选2023年全天下零星紧张性银行名单  太原市珠宝玉石破费教育基地建树  PS5展现有待后退！ 《损失之魂》早期版本激进   copyright © 2025 powered by 摩羯土星资讯   sitemap
