Novel synthesis of crystalline mesoporous tin dioxide doped with nanogold

Kuwait Journal of Science, 2018
We report the successful synthesis of a new material, a crystalline mesoporous tin dioxide (m-SnO2) framework that contains nanogold clusters (m-SnO2-Au), prepared using a direct soft method under ambient pressure.

Multifunctional Crushing and Piezoresistive Self‐Sensing in Conductive Epoxy/CNT‐Coated Polyetherimide TPMS Lattices

Advanced Engineering Materials, EarlyView.
This study reports lightweight polyetherimide triply periodic minimal surfaces lattices coated with carbon nanotube‐reinforced epoxy that combine mechanical robustness with self‐sensing. The conformal coating enhances stiffness, strength and energy absorption while enabling reliable strain monitoring.

Probing ultrafast carrier dynamics and nonlinear absorption and refraction in core-shell silicon nanowires

, 2012
We investigate the relaxation dynamics of photogenerated carriers in silicon nanowires consisting of a crystalline core and a surrounding amorphous shell, using femtosecond time-resolved differential reflectivity and transmission spectroscopy at photon ...

Real-space recipes for general topological crystalline states

, 2020
Topological crystalline states are short-range entangled states jointly protected by onsite and crystalline symmetries. While the non-interacting limit of these states, e.g., the topological crystalline insulators, have been intensively studied in band ...

Second-order topological insulators and superconductors with an order-two crystalline symmetry [PDF]

, 2018
Second-order topological insulators and superconductors have a gapped excitation spectrum in bulk and along boundaries, but protected zero modes at corners of a two-dimensional crystal or protected gapless modes at hinges of a three-dimensional crystal ...

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

Advanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

The Influence of Pressure on the Intrinsic Dissolution Rate of Amorphous Indomethacin

Pharmaceutics, 2014
New drug candidates increasingly tend to be poorly water soluble. One approach to increase their solubility is to convert the crystalline form of a drug into the amorphous form.
