Challenges of II‐VI and III‐V Blue Quantum Dot Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
Blue‐emitting electroluminescent quantum dot light‐emitting diodes (QD‐LEDs) face critical challenges that limit their practical application, including short operational lifetimes, low color purity, broad spectral linewidths, and unpredictable transient effects like blinking and positive aging.

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

open access: yesAdvanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Lithium‐Charged Gold Nanoparticles: A New Powerful Tool for Lithium Delivery and Modulation of Glycogen Synthase Kinase 3 Activity

open access: yesAdvanced Materials, EarlyView.
This study introduces glutathione‐stabilized gold nanoparticles for targeted lithium delivery (LiG‐AuNPs), enabling the controlled modulation of Glycogen Synthase Kinase‐3 (GSK‐3β). These non‐toxic, 2‐nm particles release lithium intracellularly, effectively inhibiting GSK‐3β in the brain without significant plasma lithium alterations.

Control of Covalent Bond Enables Efficient Magnetic Cooling

open access: yesAdvanced Materials, EarlyView.
Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...

Advanced Porous Materials for Maritime Carbon Capture

open access: yesAdvanced Materials, EarlyView.
Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.

Acoustic misalignment mechanism for axion dark matter

open access: yesJournal of High Energy Physics
A rotation in the field space of a complex scalar field corresponds to a Bose-Einstein condensation of U(1) charges. We point out that fluctuations in this rotating condensate exhibit sound-wave modes, which can be excited by cosmic perturbations and ...

Multi‐scale Engineered Vasculature and Hierarchical Porosity via Volumetric Bioprinting‐Guided Photopolymerization‐Induced Phase Separation

open access: yesAdvanced Materials, EarlyView.
Vascularization in bioprinted hydrogels is limited by nanoscale porosity in hydrogel bionks. Volumetric bioprinting of gelatin–norbornene phase‐separating hydrogels permits to create centimeter‐scale constructs featuring interconnected multi‐scale porosity. Light dose gradients result in spatially controlled pore dimensions. Capillary‐scale vessels are

Antibody‐Functionalized DNA Hydrogels Recognize and Isolate Living Tumor Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
We present a novel strategy using DNA Y‐motif nanostar hydrogels and DNA‐functionalized antibodies for precise live‐cell manipulation. Target cells are labeled with DNA sticky ends that hybridize with DNA Y‐motifs, enabling their incorporation and capture within the hydrogel during self‐assembly.
