In the surgical treatment of urinary diseases, ureteral stents are commonly used interventional medical devices. Although polymer with polyurethane as main constituent widely in clinic, need for secondary surgery to remove them and their propensity cause bacterial infections greatly limit effectiveness. To satisfy clinical requirements, an electrospinning-based strategy fabricate PLGA silver@graphdiyne is innovated. Silver (Ag) nanoparticles uniformly loaded on surface graphdiyne (GDY)...
Tuning the chemical potential of a solid to vicinity van Hove singularity (vHS) is well-established route discovering emergent quantum phases. In monolayer graphene, use electron-donating metal layers has recently emerged as method dope nearest vHS, evidenced by Angle-Resolved Photoemission Spectroscopy (ARPES) measurements. this work, we study spatial uniformity doping from process using spectroscopic imaging scanning tunneling microscopy (SI-STM).

The interpretation of how superconductivity disappears in cuprates at large hole doping has been controversial. To address this issue, we present an experimental study single-crystal and thin film samples La$_{2-x}$Sr$_x$CuO$_4$ (LSCO) with $x\ge0.25$. In particular, measurements bulk susceptibility on LSCO crystals $x=0.25$ indicate onset diamagnetism $T_{c1}=38.5$ K, a sharp transition to phase full shielding $T_{c2}=18$ independent field direction. Strikingly, the in-plane resistivity...
