Sesame: A Generic Architecture for Storing and Querying RDF and RDF Schema [PDF]
, 2002 RDF and RDF Schema are two W3C standards aimed at enriching the Web with machine-processable semantic data. We have developed Sesame, an architecture for efficient storage and expressive querying of large quantities of metadata in RDF and RDF Schema. Sesame's design and implementation are independent from any specific storage device.

Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse
Advanced Science, EarlyView.An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...

Angewandte Chemie, EarlyView.We introduce a new class of single‐atom electrocatalysts based on oxygen‐coordinated metal sites embedded in oxocarbon networks (M–O–C), alternative to traditional M–N–C materials. A Cu–O–C catalyst derived from oxocarbon precursors exhibits highly dispersed Cu single atoms and delivers faster glycerol oxidation kinetics and higher formate selectivity ...

Advanced Science, EarlyView.Construction of metal–flavonoid functionalized coatings on conventional bone repair materials. A one‐pot method is used to directly construct multifunctional metal–flavonoid coatings on the surface of traditional bone repair materials by selecting metal ions with osteogenic/angiogenic properties and flavonoids with reactive oxygen species scavenging ...

Angewandte Chemie, EarlyView.A low‐density, nonfluorinated moderately solvating electrolyte (MSE) composed of methyl tert–butyl ether concurrently tunes Li+ and polysulfide solvation, lowering desolvation barrier and mitigating polysulfide shuttling. It effectively stabilizes both electrodes and enables stable cycling of Li–S batteries under practical parameters at room ...

Advanced Energy Materials, EarlyView.A dual lattice‐surface strategy employing NaTi2(PO4)3 is adopted to enhance the performance of P3‐type Na0.67[Zn0.3Mn0.7]O2, whereby Ti stabilizes the bulk lattice and surface P species mitigate degradation, collectively improving high‐voltage cycling stability, Na+ diffusion, and oxygen redox reversibility through synergistic structural and ...

Raising Semantics-Awareness in Geospatial Metadata Management
ISPRS International Journal of Geo-Information, 2018 Geospatial metadata are often encoded in formats that either are not aimed at efficient retrieval of resources or are plainly outdated. Particularly, the quantum leap represented by the Semantic Web did not induce so far a consistent, interlinked ...

Advanced Energy Materials, EarlyView.A weakly solvating ether solvent, 1,2‐dimethoxypropane (DMP), is proposed for use in localized high‐concentration electrolytes (LHCEs) for lithium metal batteries (LMBs). These DMP‐based LHCEs simultaneously suppress lithium metal corrosion and cathode degradation—two interrelated processes that accelerate calendar aging of LMBs.
