Core‐passivation: A concept for stable core‐shell nanoparticles in aqueous electrocatalysis

open access: yesNano Select, 2023
The stability of nanoparticles is a major challenge in thermal and electrocatalysis. This is especially true for core‐shell nanoparticles where only a few monolayers of noble metal protect the usually non‐noble core material. In this work, we utilize the

Development of paclitaxel-loaded poly(lactic acid)/hydroxyapatite core–shell nanoparticles as a stimuli-responsive drug delivery system [PDF]

open access: yesRoyal Society Open Science, 2021
Biodegradable nanoparticles have been well studied as biocompatible delivery systems. Nanoparticles of less than 200 nm in size can facilitate the passive targeting of drugs to tumour tissues and their accumulation therein via the enhanced permeability ...

Magnetic core nanoparticles coated by titania and alumina for water and wastewater remediation from metal contaminants [PDF]

open access: yes, 2017
Nanomaterials have been widely used for remediation of contaminated streams. However, using nanomaterials within water and wastewater might be dangerous since fate and health impact of nanoparticles is still unknown.

Single-shot 3D coherent diffractive imaging of core-shell nanoparticles with elemental specificity. [PDF]

open access: yes, 2018
We report 3D coherent diffractive imaging (CDI) of Au/Pd core-shell nanoparticles with 6.1 nm spatial resolution with elemental specificity. We measured single-shot diffraction patterns of the nanoparticles using intense x-ray free electron laser pulses.
