Effects of water safety knowledge on high-risk swimming behaviours among Chinese secondary school students: a moderated mediation model

open access: yesFrontiers in Psychology
BackgroundThe dangers of drowning as a major global public health problem continue to receive international attention. Current literature lacks to describe the mechanism of action of water safety knowledge on high-risk behaviours in swimming.

Block Copolymers: Emerging Building Blocks for Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
This review addresses how block copolymer (BCP) physics and rheology have led to the widespread use of BCPs in advanced additive manufacturing techniques, with particular emphasis on the untapped potential of these nanostructured materials toward achieving multi‐scale architected materials with unique, programmable material properties.

Coherent Control of Nitrogen Nuclear Spins via the VB−${\rm V}_B^-$‐Center in Hexagonal Boron Nitride

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates coherent control of 15N nuclear spins coupled to VB−${\text{V}}_{\text{B}}^{-}$ centers in isotope‐enriched hexagonal boron nitride. Selective addressing via spin‐state mixing enables Rabi driving, quantum gates, and coherence times exceeding 10 μs$\umu{\rm s}$.

Humor appreciation and sensation seeking: Invariance of findings across culture and assessment instrument? [PDF]

open access: yes, 2017
It was hypothesized that sensation seeking (SS) is able to predict both the structure and content of jokes and cartoons. Five hypotheses were derived and tested in two samples from Spain and Germany comprising a total of 434 participants.

Suppression of Photo‐Mediated Traps in Integrated Organic Photovoltaic–Photodetector Devices via N‐Type Self‐Assembly‐Driven Interfacial Engineering

open access: yesAdvanced Functional Materials, EarlyView.
Conventional unstable electron transport layers (ETLs) limit self‐powered organic sensors. This work resolves this by developing a n‐type self‐assembled monolayer (SAM), “3‐PAPh”. This SAM forms a chemically stable and structurally ordered interface that fundamentally suppresses defect formation.

Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges

open access: yesAdvanced Functional Materials, EarlyView.
Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).

La práctica de actividad físico-deportiva de riesgo como herramienta preventiva de conductas desajustadas psicosocialmente [PDF]

open access: yes, 2001
La Teoría de Búsqueda de Sensaciones elaborada por Zuckerman y colaboradores plantea como algunas personas, con alta búsqueda de sensaciones, les resultan placenteras las actividades excitantes, buscando experiencias nuevas y poco usuales, o asumiendo ...

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

open access: yesAdvanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

The Developmental Mismatch in Structural Brain Maturation during Adolescence [PDF]

open access: yes, 2014
Regions of the human brain develop at different rates across the first two decades of life, with some maturing before others. It has been hypothesized that a mismatch in the timing of maturation between subcortical regions (involved in affect and reward ...
