Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

open access: yesAdvanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

Burnout and associated occupational stresses among Chinese nurses: A cross-sectional study in three hospitals

open access: yesPLoS ONE, 2020
Background There is literature scarcity relating to burnout and other work stresses in relation to Chinese nursing-workforce performance. Objectives To assess the relationship between self-esteem versus burnout; and effort-reward ratio versus ...

Breaking Bottlenecks in Solid Electrolyte Discovery With Large Artificial Intelligence Models

open access: yesAdvanced Materials, EarlyView.
Large AI models are presented as a route to break key bottlenecks in solid electrolyte discovery by linking materials databases, machine‐learning interatomic potentials, large language models, and autonomous experiments. This perspective highlights how AI can accelerate the identification of solid electrolytes with fast ion transport, stable interfaces,

Coordination Bridges in Confined‐Water Domains Enable Partially Desolvated Zn2+ Transport in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
A multifunctional polymer layer with amide and imidazolium groups simultaneously suppresses dendrite growth and hydrogen evolution in Zn‐ion batteries. By providing Zn2+ binding sites and forming a confined‐water domain that acts as a coordination bridge, it boosts single‐ion conductivity and stability, enabling 4000 stable cycles in Zn‐I2 full cells ...

“Activation‐Resistance Elimination” Regulation by Lanthanide/Transition Metal Ion‐Coordinated Nanostructures Intensifies Cuproptosis and Tumor Immunotherapy

open access: yesAdvanced Materials, EarlyView.
The lanthanide/transition metal ion coordination nanoparticles, La‐Cu@Lap/IWR‐1, with optimized coordination, have been proven to achieve remarkable results in realizing comprehensive tumor cuproptosis through efficient cuproptosis activation and multidimensional resistance elimination, thereby synchronously realizing the synergistic antitumor effects ...

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

open access: yesAdvanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Diurnal cortisol decline by Effort-Reward-Imbalance (ERI) status.

open access: yes, 2013
Figure 1. Diurnal cortisol decline (adjusted means including 95% CI) by ERI status, adjusted for age, gender, ethnicity, time of waking and time since waking. ERI: effort-reward-imbalance ratio; SD: standard deviation.

A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration

open access: yesAdvanced Materials Interfaces, EarlyView.
The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

open access: yesAdvanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.
