Managing polyglot systems metadata with hypergraphs [PDF]

open access: yes, 2018
A single type of data store can hardly fulfill every end-user requirements in the NoSQL world. Therefore, polyglot systems use different types of NoSQL datastores in combination.

High‐Performance Quasi‐Solid‐State Calcium‐Ion Batteries from Redox‐Active Covalent Organic Framework Electrolytes

open access: yesAdvanced Science, EarlyView.
Quasi‐solid‐state calcium‐ion batteries (QSSCIBs) employing redox‐active covalent organic frameworks (COFs) based electrolytes are developed. The COFs’ crystalline porous structures, featuring aligned carbonyl groups, enabled high Ca2⁺ conductivity, supported by molecular dynamics simulations of the ion transport mechanism.

Support‐Induced Interfacial Effects Steer Methanol Selectivity in CO2 Electroreduction by Immobilized Cobalt Phthalocyanine

open access: yesAngewandte Chemie, EarlyView.
Immobilizing CoPc on a carbon support switches its CO2 reduction selectivity from CO to CH3OH. Multiscale simulations reveal that the support actively modulates the catalytic environment by inducing desolvation of bottom layer of CoPc, which lowers the protonation barrier while leaving CO desorption nearly unaffected.

Enhancing Cycling Stability of Aqueous Aluminum‐Metal Batteries via LaCl3‐Modulated Interfacial Reactions

open access: yesAdvanced Science, EarlyView.
In the aqueous AlCl3 electrolyte of aluminum‐metal batteries, the introduction of LaCl3 adjusts the solvation structure of Al3+ and enhances its diffusion level. The oxide precipitate formed by La3+ covers the aluminum metal anode and effectively alleviates corrosion reactions, thereby improving the cycling stability of the battery.

Libraries and Information Systems Need XML/RDF... but Do They Know It? [PDF]

open access: yes, 2005
This article presents an approach to the uses of XML (eXtensible Markup Language) and Semantic Web technologies in the field of information services, focusing mainly on the creation and management of digital libraries compared to traditional libraries,

Cathode Electrolyte Interphase Engineering by Quaternized Chitosan for Stabilized Li–SPAN Batteries

open access: yesAdvanced Science, EarlyView.
In this work, quaternized chitosan (QCS) is reported as an additive optimizing the sulfurized polyacrylonitrile (SPAN) cathode/electrolyte interphase (CEI). Its high positive charge density adsorbs PF6− anions, enriching the Helmholtz layer with aggregates. This promotes rapid anion desolvation, forming an anion‐derived CEI enriched in LiF.

Trifunctional DOPO‐Engineered Polypropylene Separator With Li⁺‐Concentrating Interfaces for High‐Safety Lithium‐Ion Batteries Under Extreme Conditions

open access: yesAdvanced Science, EarlyView.
A DOPO‐based cross‐linked polymer creates a multifunctional separator for lithium‐ion batteries. It concurrently addresses safety (flame retardancy, thermal stability) and performance (enhanced Li+ transport, capacity retention), pioneering a novel approach to high‐performance battery design. Abstract This study develops a cross‐linked polymer modified

Using LIDO for Evolving Object Documentation into CIDOC CRM

open access: yesHeritage, 2019
Over the last years, many projects and institutions have worked on transforming object documentation from several existing cataloguing systems into a CIDOC Conceptual Reference Model (CIDOC CRM) compliant graph representation, as expressed in RDF.
