A series transformation formula and related polynomials

International Journal of Mathematics and Mathematical Sciences, 2005
We present a formula that turns power series into series of functions. This formula serves two purposes: first, it helps to evaluate some power series in a closed form; second, it transforms certain power series into asymptotic series.

Mesenchymal Stem Cell‐Inspired Microneedle Platform for NIR‐responsive Immunomodulation and Accelerated Chronic Wound Healing

Advanced Materials, EarlyView.
The research demonstrates a Mesenchymal Stem Cell‐inspired microneedle platform (MSCi@MN) that addresses chronic diabetic wounds by combining MSC‐derived extracellular nanovesicles (NV)–DNA conjugates in microneedle tips with photothermal MXene in the patch layer.

The Exact Density of the Eigenvalues of the Wishart and Matrix-Variate Gamma and Beta Random Variables

Mathematics
The determination of the distributions of the eigenvalues associated with matrix-variate gamma and beta random variables of either type proves to be a challenging problem. Several of the approaches utilized so far yield unwieldy representations that, for

Structural Exploration of Zirconium Metal–Organic Frameworks Through Linker Desymmetrization and Modulator Compensation

Advanced Materials, EarlyView.
A linker‐desymmetrization‐modulator‐compensation (LDMC) strategy for constructing structurally diverse Zr‐MOFs is reported. This approach reduces linker symmetry to create defects in Zr‐clusters, which can be compensated for by modulator coordination. Using this approach, we synthesized PCN‐1005 and PCN‐1006, featuring unprecedented Zr‐clusters. In PCN‐

From Thin Films to Nanodots: Bottom‐Up Integration of Fe3O4 on Nb:STO for Functional Oxide Nanostructures

Advanced Materials, EarlyView.
Scalable bottom‐up fabrication of Fe3O4 nanodots on Nb:SrTiO3 using anodic alumina templates enables long‐range ordered arrays with diameters down to 30 nm. STEM highlights the epitaxial growth of Fe3O4 films on Nb:SrTiO3. Complementary polarized neutron reflectometry (PNR) and X‐ray magnetic circular dichroism (XMCD) measurements on continuous films ...

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Meissner Effect and Nonreciprocal Charge Transport in Non‐Topological 1T‐CrTe2/FeTe Heterostructures

Advanced Materials, EarlyView.
This work demonstrates interface‐induced superconductivity (Tc ∼12 K) with a robust Meissner effect and pronounced nonreciprocal transport in epitaxial 1T‐CrTe2/FeTe heterostructures, where 1T‐CrTe2 is a 2D ferromagnet, and FeTe is an antiferromagnetic metal.

Serotonergic System‐Targeted Nucleic Acid Hydrogel Coordinates Excitability Restoration and Circuit Reconstruction for Spinal Cord Injury Therapy

Advanced Materials, EarlyView.
The study reports a DNA/RNA heteroduplex hydrogel (SeroPTEN‐CG) that undergoes DNase‐mediated hydrogel‐to‐nanogel transition for spinal cord injury therapy by targeting the serotonergic system, combining 5‐hydroxytryptamine (5‐HT)‐mediated excitability restoration to reactivate dormant interneurons with phosphatase and tensin homolog (PTEN)‐targeted ...
