The undesirable dendrite growth induced by non-planar zinc(Zn)deposition and low Coulombic efficiency resulting from severe side reactions have been long-standing challenges for metallic Zn anodes and substantially impede the practical application of rechargeable aqueous Zn metal batteries(ZMBs).Herein,we present a strategy for achieving a high-rate and long-cycle-life Zn metal anode by patterning Zn foil surfaces and endowing a Zn-Indium(Zn-In)interface in the *** accumulation of electrons in the microchannel and the zincophilicity of the Zn-In interface promote preferential heteroepitaxial Zn deposition in the microchannel region and enhance the tolerance of the electrode at high current ***,electron aggregation accelerates the dissolution of non-(002)plane Zn atoms on the array surface,thereby directing the subsequent homoepitaxial Zn deposition on the array ***,the planar dendrite-free Zn deposition and long-term cycling stability are achieved(5,050 h at 10.0 mA cm^(−2) and 27,000 cycles at 20.0 mA cm^(−2)).Furthermore,a Zn/I_(2) full cell assembled by pairing with such an anode can maintain good stability for 3,500 cycles at 5.0 C,demonstrating the application potential of the as-prepared ZnIn anode for high-performance aqueous ZMBs.

The spin-orbit assisted Mott insulator α-RuCl3is a prime candidate for material realization of the Kitaev quantum spin *** little attention has been paid to charge degrees of freedom, charge effects, such as electric polarization, may arise in this system. Here, we report distortion-induced local electric polarization in α-RuCl3as evidenced by single-crystal X-ray diffraction,second harmonic generation（SHG） and dielectric measurements. The SHG signal appears at room temperature and develops substantially in the Kitaev paramagnetic state when short-range spin correlations come into play. Despite sizable pyroelectric currents in the Kitaev paramagnetic state, the absence of hysteresis in the polarization-electric field（P-e） points to the shortrange nature of electric polarization. This localized electric polarization is likely the result of distortion-induced charge dimerization, achieved through virtual hopping-induced charge redistribution. In addition, the electric polarization is boosted by short-range spin correlations via spin-phonon coupling in the Kitaev paramagnetic state. Our results emphasize the importance of charge degrees of freedom in α-RuCl3, which establish a novel platform to investigate charge effects in Kitaev materials.

Data harmonization and documentation of the data processing are essential prerequisites for enabling Canonical Analysis *** recently revised Terabyte-scale air quality database system,which the Tropospheric Ozone Assessment Report(TOAR)created,contains one of the world's largest collections of near-surface air quality measurements and considers FAIR data principles as an integral part.A special feature of our data service is the on-demand processing and product generation of several air quality metrics directly from the underlying *** this paper,we show that the necessary data harmonization for establishing such online analysis services goes much deeper than the obvious issues of common data formats,variable names,and measurement units,and we explore how the generation of FAIR Digital Objects(FDO)in combination with automatically generateddocumentation may support Canonical Analysis Workflows for airquality and related data.

Canonical Workflows to Make Data FAIR

Data Intelligence 2022年第2期4卷 286-305页

作者： Peter Wittenburg Alex Hardisty Yann Le Franc Amirpasha Mozaffari Limor Peer Nikolay A.Skvortsov Zhiming Zhao Alessandro Spinuso FDO Forum Cardiff University e Science Factory forschungszentrum Jülich GmbH Yale University Russian Academy of Sciences University of Amsterdam Royal Netherlands Meteorological Institute (KNMI)

The FAIR principles have been accepted globally as guidelines for improving data-driven science and data management practices, yet the incentives for researchers to change their practices are presently weak. In addition, data-driven science has been slow to embrace workflow technology despite clear evidence of recurring practices. To overcome these challenges, the Canonical Workflow Frameworks for Research(CWFR) initiative suggests a large-scale introduction of self-documenting workflow scripts to automate recurring processes or fragments thereof. This standardised approach, with FAIR Digital Objects as anchors, will be a significant milestone in the transition to FAIR data without adding additional load onto the researchers who stand to benefit most from it. This paper describes the CWFR approach and the activities of the CWFR initiative over the course of the last year or so, highlights several projects that hold promise for the CWFR approaches, including Galaxy, Jupyter Notebook, and RO Crate, and concludes with an assessment of the state of the field and the challenges ahead.
