Stretching-Induced 2D-to-3D Shape Transformation of an Elastic Composite for Sensitivity-Tailorable Soft Electronics.

The shapes of rubbers and elastomers are challenging to alter, and current methods relying on permanent plasticity and dynamic cross-linking strategies are usually laborious and can inevitably compromise the network elasticity. Here, we report a photoresponsive elastic composite that can be programmed into 3D shapes by first UV light irradiation and then stretching. The composite comprises ethylene propylene rubber as the elastic substrate and photoliquefiable azobenzene small molecules as the responsive filler.

Emissions of Formamide and Ammonia from Foam Mats: Online Measurement Based on Dopant-Assisted Photoionization TOFMS and Assessment of Their Exposure for Children.

Formamide has been classified as a Class 1B reproductive toxicant to children by the European Union (EU) Chemicals Agency. Foam mats are a potential source of formamide and ammonia. Online dopant-assisted atmospheric pressure photoionization time-of-flight mass spectrometry (DA-APPI-TOFMS) coupled with a Teflon environmental chamber was developed to assess the exposure risk of formamide and ammonia from foam mats to children.

Helical carbon nanofibers modified with FeO as a high performance anode material for lithium-ion batteries.

Helical carbon nanofibers (HCNFs) modified with Fe2O3 (Fe2O3/HCNFs) with a particle size of about 10-20 nm were first introduced for potential use as a novel anode material for lithium-ion batteries (LIBs). Fe2O3/HCNFs were successfully prepared via a chemical liquid deposition (CLPD) method in this study. HCNFs with a special three-dimensional helical structure improve the conductivity and also provide a strong supporting network space for stress and strain during the volume expansion of Fe2O3 nanoparticles.

The Interaction Between Phonological and Semantic Processing in Reading Chinese Characters.

The contemporary models of visual word recognition reached a consensus on a cooperative division of labor between phonological and semantic processing. We examine how reading is influenced by the interaction of two processing in Chinese character reading since the ideographic property of the Chinese writing system is perfectly suitable to address this issue. The current study investigated whether Chinese character reading requires the interaction between orthography-to-phonology consistency and semantic processing of the whole character (imageability, Experiment 1) or the semantic radical (transparency, Experiment 2).
