▲ Abstract ：
Molecules with heavy, radioactive nuclei promise extreme sensitivity to fundamental nuclear and particle physics. However, these nuclei are available in limited quantities, which challenges their use in precision measurements. Here we demonstrate the gas-phase synthesis, cryogenic cooling, and high-resolution laser spectroscopy of radium monohydroxide, monodeuteroxide, and monofluoride molecules (226RaOH, 226RaOD, and226RaF) in a tabletop apparatus by combining trace radioactive target production protocols, optically driven chemistry in a cryogenic buffer gas, and low-background spectroscopic detection methods. The molecules are cooled in the lab frame, creating conditions that are the same starting points as those for many current molecular precision measurement and quantum information experiments. This approach can be readily applied to a wide range of species and establishes key capabilities for molecular quantum sensing of exotic nuclei.

▲ Abstract ：
The ultimate goal of information storage is single-electron memory. Quantum mechanics predicts that two distinguishable quantum states can be realized by confining a single electron within an ultrasmall space. However, scaling down such devices paradoxically amplifies fringe capacitance effects, which hinders the experimental observation of single-electron memory. We report a two-dimensional single-electron memory device based on a coplanar drain-channel-source structure that suppressed fringe capacitance, exhibiting a nonvolatile threshold voltage shift of 0.5 volts after the change of a single electron. Two intriguing quantum behaviors have also been verified regarding the programming voltage. Additionally, we have predicted and observed a distinctive quantum memory effect: A quantum state is cut off by density of states scissors.

▲ Abstract ：
Ongoing demands for smaller and more energy-efficient electronic devices necessitate alternative interconnect materials with lower electrical resistivity at reduced dimensions. We report the synthesis of Weyl semimetal niobium arsenide (NbAs) nanowires through thermomechanical nanomolding with single crystallinity and controlled diameters down to 40 nanometers. The resistivity of NbAs nanowires decreases with decreasing diameter, and 40-nanometer-diameter nanowires exhibited a room-temperature resistivity of 10.5 ± 1.9 microhm·centimeters, which is ~70% lower than their bulk counterpart. Calculations attribute this resistivity reduction to su***ce-dominant conduction with a long carrier lifetime at finite temperatures. Further characterization of nanowires and bulk crystals revealed high breakdown current density, stability, and thermal conductivity. These properties highlight the potential of NbAs nanowires as next-generation interconnects that could surpass the limitations of current copper-based interconnects.

钙钛矿太阳能电池（PSCs）的贸易化需求在气候前提下可扩大年夜大年夜大年夜大年夜聚积平均的钙钛矿薄膜。可是 ，在长时分涂覆过程中 ，亚稳钙钛矿的空间非平均退步会招致薄膜不平均性 。
研究组展示了经由过程锁相计策完成的α相FAPbI3（个中FA为甲脒）时空平均结晶 ，该计策在除夜面积涂覆过程中创建了一个静态演变 、具有湿度缓冲感染的晶间群集 。该编制阻拦了气候湿度激起的过迟到化 ，消弭标的方针不平均性 。

▲ Abstract ：
Commercializing perovskite solar cells (PSCs) will likely require the scalable deposition of homogeneous perovskite films under ambient conditions. However, the spatially heterogeneous degradation of metastable perovskites during prolonged coating leads to nonuniformity. Here, we demonstrate spatiotemporally homogeneous crystallization of α-phase FAPbI3(where FA is formamidinium) enabled by a phase-locking strategy that establishes a dynamically evolving, moisture-buffering intergranular network during large-area printing. This method prevents the premature degradation caused by ambient humidity, eliminating directional inhomogeneity. Blade-coated PSCs achieved a 26.7% power conversion efficiency (PCE; 26.1% certified), and rigid and flexible 100-square-centimeter modules reached 21.5 and 19.5%, respectively. Improved morphological homogeneity mitigated localized degradation and suppressed self-amplifying aging pathways. Encapsulated devices retained more than 90% of their initial PCE after 1500 hours of 85°C maximum power point tracking in ambient air.

▲摘要 ：
湖泊在聚积物中储存除夜量碳 ，对气候笼统调剂具有次要感染 。可是 ，湖泊开放后这些碳的回宿尚不了然 。
研究组采取时空更调编制 ，连络聚积物岩芯 、二氧化碳通量测量和远感数据，量化了全国上最除夜的开放湖泊（咸海）的无机碳丧损掉落踪落。自1960年以来 ，泄漏的湖床聚积物已释放204±53太克碳（Tg C） ，而植被展开抵消的碳窘蹙1% 。
纳进这些碳排放会改削区域碳预算 ，使咸海盆地从假定的地盘独霸改削碳汇改削成净碳源。若湖泊水位恢复 ，则可阻拦出格165±13 Tg C的释放 ，这使得湖泊恢复不成是一项生态和人道主义要务 ，也是一次气候笼统减缓的机会 。
▲ Abstract ：
Lakes store large quantities of carbon in their sediments, contributing to climate regulation. Yet the fate of this carbon after lake desiccation remains unclear. Using a space-for-time substitution approach, combining sediment cores, carbon dioxide flux measurements, and remote sensing, we quantified organic carbon losses from the world’s largest desiccated lake, the Aral Sea. Since 1960, exposed lake bed sediments have released 204 ± 53 teragrams of carbon (Tg C), with vegetation growth offsetting less than 1%. Incorporating these emissions alters the regional carbon budget, transforming the Aral Sea basin from a presumed land-use-change carbon sink into a net source. Reflooding the sea could prevent an additional 165 ± 13 Tg C release, reframing restoration not only as an ecological and humanitarian imperative but also as a climate mitigation opportunity.

▲ Abstract：
Oceanic transform faults have been considered conservative, shear-dominated boundaries, yet their proximity to magmatic systems implies fluid involvement. In this work, we discovered tidally modulated tremor at the Gofar transform fault along the East Pacific Rise. Tremor amplitude correlates with semidiurnal tides during periods of sparse seismicity and low in situ compressional to shear wave velocity ratio (Vp/Vs), but this correlation weakens following earthquake swarms accompanied by high Vp/Vs. We propose a valve-like sealing-drainage dynamic process where sealing traps volatiles and boosts tidal sensitivity, sustaining tremor activity until rupture opens high porosity and permeability pathways, which silences tremors, triggers microseismicity, and resets the system through hydrothermal resealing. Thus, transform faults are likely permeable and tide critical, with energy release oscillating between tremors and rupture, paced by magmatic volatile supply and healing.
