MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

open access: yesAdvanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Radial Symmetry of Self-Similar Solutions for Semilinear Heat Equations

open access: yes, 2000
The symmetry properties of positive solutions of the equationΔu+12x·∇u+1p−1u+up=0inRn,where n⩾2, p>(n+2)/n, was studied. It was proved that u must be radially symmetric about the origin provided u(x)=o(|x|−2/(p−1)) as |x|→∞, and that there exist non ...

Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...

Anion‐Exchange‐Enabled Hydrogel Electrolytes With High Zn2+ Transference for Dendrite‐Free Flexible Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A high‐Zn2+‐transference hydrogel electrolyte of ex‐PDADAM is developed via anion exchange at quaternary ammonium sites, achieving high Zn2+ transference number (0.86), ionic conductivity (8.10 mS cm−1), and toughness (51.25 MJ m−3). Symmetric cells are operated stably for over 2000 h, while flexible pouch cells retain 90.9% capacity after 300 cycles ...

Development of a Three‐Axis Planar Hall Magnetoresistance Sensor Using a Superparamagnetic Nanoparticle‐Based Flux Guide

open access: yesAdvanced Functional Materials, EarlyView.
A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.

Weighted eigenvalue problems for the p-Laplacian with weights in weak Lebesgue spaces

open access: yesElectronic Journal of Differential Equations, 2011
We consider the nonlinear eigenvalue problem $$ -Delta_p u= lambda g |u|^{p-2}u,quad uin mathcal{D}^{1,p}_0(Omega) $$ where $Delta_p$ is the p-Laplacian operator, $Omega$ is a connected domain in $mathbb{R}^N$ with $N>p$ and the weight function $g$

Symmetries and covering maps for the minimal tension string on AdS 3 × S 3 × T 4

open access: yesJournal of High Energy Physics
This paper considers a recently-proposed string theory on AdS 3 × S 3 × T 4 with one unit of NS-NS flux (k = 1). We discuss interpretations of the target space, including connections to twistor geometry and a more conventional spacetime interpretation ...
