Tumor‐tropic human mesenchymal stem cells (hMSCs) were used as delivery vehicles for magnetotheranostic gold–iron oxide nanoflowers. Magnetic particle imaging of the iron component demonstrated widespread intratumoral distribution and sustained retention in contrast to injection of naked nanoflowers.

By applying Mawhin's continuation theorem, we study the existence of positive periodic solutions for a second-order neutral functional differential equation $$ ((x(t)-cx(t-\sigma)))''+f(x(t)) x'(t)+g(t,x(t-\delta))=e(t), $$ where g has a strong ...

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

In this article, we first establish some results on composition of Stepanov-like weighted pseudo almost automorphic functions so called class r and class infinity under a uniform continuity condition with respect to L^p-norm.

Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

Boundary value problems and differentiability for neutral functional differential equations
This paper is concerned with the existence of solutions of a boundary value problem for neutral differential equations. Specifically, we consider the problem \[ (*)\quad (d/dt)(Dx_ t-g(t,x_ t))=Lx_ t+f(t,x_ t),t\in (0,\tau],Mx_ 0+\int^{\tau}_{0}[d\mu (t)]x_ t=\gamma, \] where M and \(\mu\) (t) are linear operators and \(\gamma\) is a fixed element of a

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified
