Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Changes in drinking as predictors of changes in sickness absence: a case-crossover study [PDF]

open access: yes, 2012
BACKGROUND: We investigated whether changes in alcohol use predict changes in the risk of sickness absence in a case-crossover design. METHODS: Finnish public sector employees were surveyed in 2000, 2004 and 2008 on alcohol use and covariates.

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

open access: yesAdvanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

Economic incentives and long-term sickness absence: The indirect effect of replacement rates on absence behavior [PDF]

open access: yes, 2015
Reductions in SI replacement levels has been a widely used instrument to lower sickness absence rates. The idea is that increasing the direct cost of absence would lower the absence rate.

A Bespoke Programmable Interpenetrating Elastomer Network Composite Laryngeal Stent for Expedited Paediatric Laryngotracheal Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
A programmable interpenetrating double‐network architecture, created via 3D‐TIPS printing and resin infusion, synergistically combines thermoplastic and thermosetting elastomers to balance structural rigidity and surface softness—crucial for paediatric laryngeal stents.

Sickness Absence and Local Cultures [PDF]

open access: yes
Sickness absence has been found to vary substantially across geographical areas. There are large differences between different countries but also between different regions within a particular country.

Spatially Resolved Click Patterning of Dyes on Graphene for 2D Hybrids with Regiotunable Fluorescence

open access: yesAdvanced Functional Materials, EarlyView.
Well‐structured graphene hybrid architectures featuring spatially resolved fluorescent properties represent a promising but so‐far elusive synthetic target. A robust and straightforward method for fabricating well‐organized graphene‐dye hybrid nanoassemblies through a combination of reductive patterning and conventional click chemistry is presented ...

Risk factors of sickness absence

open access: yesطب کار, 2016
Introduction: Absenteeism is one of the challenging issues in managing human resources. Many social, economic and personal factors may affect sickness absence. We studied effects of some personal factors on sickness absence in a governmental organization.
