Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

Advanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

3D Bioprinted Glioblastoma Multiforme Models: How the Extracellular Matrix Glycosignature Influences Drug Response

Advanced Functional Materials, EarlyView.
Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

High-temperature ferrimagnetic order triggered metal-to-insulator transition in CaCu3Ni2Os2O12

Nature Communications
Ferromagnetic order-induced insulator-to-metal transitions via the double exchange mechanism have been studied widely. In contrast, ferromagnetic or ferrimagnetic spontaneous magnetization induced metal-to-insulator transitions (MITs), especially ...

Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

Advanced Functional Materials, EarlyView.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Study on correlation between exothermic risk of coal gangue and microscopic groups

Meikuang Anquan
In order to explore the exothermic hazard of coal gangue in the process of spontaneous combustion and its correlation with microscopic groups, the microstructure and exothermic characteristics of four kinds of coal gangue(CG1、CG2、CG3、CG4) were tested by ...

Spontaneous Hemopneumothorax: An Overlooked Life-Threatening Condition

, 2009
Spontaneous hemopneumothorax is a rare clinical entity. A large spontaneous hemopneumothorax is life-threatening, and mortality increases with delayed recognition and intervention.

Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks

Advanced Functional Materials, EarlyView.
This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.

Can We Design Spontaneity? Hayek, Design, and the Normative Appeal of Spontaneous Orders

Erasmus Journal for Philosophy and Economics
Spontaneous orders are an essential concept in political theory and political economy. Such orders entail the impossibility of predicting outcomes in detail and hence controlling and directing social processes. Many phenomena characterizing contemporary
