Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

open access: yesAdvanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...

Autonomous Machine Learning‐Based Classification and Arrangement of Submillimeter Objects Using a Capillary Force Gripper

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study presents an automated system integrating a capillary force gripper and machine learning‐based object detection for sorting and placing submillimeter objects. The system achieved stable and simultaneous manipulation of four object types, with an average task time of 86.0 seconds and a positioning error of 157 ± 84 µm, highlighting its ...

Post-magmatic hydrothermal origin of late Jurassic Liwu copper polymetallic deposits, western China: Direct chalcopyrite Re-Os dating and Pb-B isotopic constraints

open access: yesOre Geology Reviews, 2017
Abstract The Liwu copper polymetallic deposits are located in the Jianglang Tectonic Dome in the southeastern Songpan-Ganzi Fold Belt. The deposits contain more than 0.8 million tonnes (Mt) of Cu, 0.5 Mt of Zn, 133 t of Ag and 1300 t of Co. However, the detailed geologic features, formation ages and metallogeny of these deposits remain poorly ...

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...

CSF‐Compartmentalized Antibody Glycoprofiles in NMDAR Encephalitis Associate with Etiology and Functional Recovery

open access: yesAnnals of Neurology, EarlyView.
Objective To characterize Fc‐glycosylation profiles in patients with anti‐N‐methyl‐D‐aspartate receptor encephalitis (NMDARe) and assess their association with antibody compartmentalization (cerebrospinal fluid [CSF] vs serum), disease triggers (viral, tumor‐related or idiopathic), and 1‐year outcomes.

Tectonic setting and metallogenic chronology of the Ashele Cu–Zn deposit in Xinjiang, NW China: Constraints from Re-Os dating of pyrite, U-Pb dating of zircon and Hf isotopes

open access: yesOre Geology Reviews, 2019
Abstract The Ashele Cu-Zn deposit, an important volcanogenic massive sulfide (VMS) deposit, is located in the centre of the Ashele volcano-sedimentary basin of the Altay metallogenic belt, North Xinjiang, NW China. The No. 1 orebody is located between the roof basalt and the base tuff. The roof basalt yielded a zircon U-Pb age of 342 ± 4.6 Ma (MSWD =

A new precision measurement of the {\alpha}-decay half-life of 190Pt

open access: yes, 2017
A laboratory measurement of the $\alpha$-decay half-life of $^{190}$Pt has been performed using a low background Frisch grid ionisation chamber. A total amount of 216.60(17) mg of natural platinum has been measured for 75.9 days.

Ore-formation mechanism of the Weilasituo tin–polymetallic deposit, NE China: Constraints from bulk-rock and mica chemistry, He–Ar isotopes, and Re–Os dating

open access: yesOre Geology Reviews, 2019
Abstract China’s W–Sn resources are dominant on a global scale. A series of Sn–polymetallic deposits has been found in recent years at depth on the flanks of known volcanic–subvolcanic Cu–Pb–Zn–Ag deposits in the Southern Great Xing’an Range, NE China.
