Development of coating formulation with silica–titania core–shell nanoparticles against pathogenic fungus [PDF]

Royal Society Open Science, 2018
In the present study, we developed an antifungal coating formulation using silica, titania and silica–titania core–shell nanoparticles individually. The idea behind the synthesis of core–shell nanoparticles was to use the mechanical strength of silica ...

Role of Surface Defects on Photoinduced Reactivity in SiO₂ Nanoparticles

Inorganics, 2023
Silica nanostructured materials find application in different fields, since they are cheap, versatile, and easy to functionalize as materials. However, silica reactivity has not been deeply investigated yet, mainly due to a poor understanding of how it ...

The size and polydispersity of silica nanoparticles under simulated hot spring conditions [PDF]

, 2008
The nucleation and growth of silica nanoparticles in supersaturated geothermal waters was simulated using a flow-through geothermal simulator system. The effect of silica concentration ([SiO2]), ionic strength (IS), temperature (T) and organic additives ...

Mesoporous silica nanoparticles as nanocarriers

Chemical Communications, 2011
Modern nanomedicine aims at delivering drugs or cells specifically to defective cells; therefore, this calls for developing multifunctional nanocarriers for drug delivery and cell-tracking. Mesoporous silica nanoparticles (MSNs) are well suited for this task. In this feature article, we highlight the strategies in the synthesis and functionalization of

Aggregation of silica nanoparticles in concentrated suspensions under turbulent, shear and extensional flows. [PDF]

, 2013
The production of nanoparticles in concentrated suspensions requires strict control of the stability of the systems which are strongly influenced by the physico-chemical properties and the hydrodynamic conditions they are placed in. This study deals with

Toxicology of silica nanoparticles: an update [PDF]

Archives of Toxicology, 2017
Large-scale production and use of amorphous silica nanoparticles (SiNPs) have increased the risk of human exposure to SiNPs, while their health effects remain unclear. In this review, scientific papers from 2010 to 2016 were systematically selected and sorted based on in vitro and in vivo studies: to provide an update on SiNPs toxicity and to address ...

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

Advanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

Advanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...
