Physical activity and cognitively difficulties in adolescents: A cross-sectional study of 13,677 participants.

Background: Physical activity (PA) has been shown to improve cognitive ability in adolescents. However, there is evidence for the impact of different PA characteristics (e.g.

The impact of processing voltage of wire electric discharge machining on the performance of Mo doped V-VO based Archimedean micro-supercapacitors.

Vanadium oxide-based electrode materials have attracted increasing attention owing to their extraordinary capacitance and prolonged lifespan, excellent conductivity and outstanding electrochemical reversibility. However, the development of vanadium oxide-based integrated electrodes with outstanding capacitive performance is an enduring challenge. This research reports a facile method for structuring 3D Archimedean micro-supercapacitors (AMSCs) composed of Mo doped V-VO (Mo@V-VO) based integrated electrodes with designable geometric shape, using computer-aided wire electric discharge machining (WEDM).

Fabrication of Fe-FeO based 3D coplanar microsupercapacitors by electric discharge rusting of pure iron substrates.

Iron oxides with advanced functional properties show great potential for applications in the fields of water splitting, drug delivery, sensors, batteries and supercapacitors. However, it is challenging to develop a simple and efficient strategy for fabricating patterned iron oxide based electrodes for supercapacitor applications. Herein, a facile, simple, scalable, binder-free, surfactant-free and conductive additive-free electric discharge rusting (EDR) technique is proposed to directly synthesize FeO oxide layer on a pure iron substrate.
