Nanocontainer in der Analytik

Angewandte Chemie, 2019
AbstractNanocontainer, wie mesoporöse Siliciumoxidpartikel und Polymersomen, sind vielseitige Strukturen, die Löcher oder Poren enthalten, die für den Einschluss von niedermolekularen Verbindungen und für die Einführung spezifischer Funktionalitäten verwendet werden. Sie finden weitreichende Anwendungen in Wirkstofftransportsystemen, in der Biomedizin,

pH-Sensitive Nanocontainers

Advanced Materials, 2001
Water-soluble polyelectrolyte nanocapsules can be synthesized by vesicular or emulsion polymerization via core–shell latexes. These particles show a reversible pH- and ionic strength-dependent swelling transition causing a considerable increase (decrease) of their radius.

A nanocontainer for the storage of hydrogen

Carbon, 2007
Molecule hydrogen is known to have a weak van der Waals potential, which makes it difficult to raise its storage efficiency for physisorption based methods. In this report, we explore the other side of such a weak potential, the well-known compressibility of hydrogen. A (20, 0) single wall carbon nanotube based nanocontainer is designed, in which a C60

Viruses and protein cages as nanocontainers and nanoreactors

Journal of Materials Chemistry, 2009
In this highlight, recent studies related to the use of viral capsids and other protein cages as nanocontainers and nanoreactors are discussed. The templating of chemical reactions within these biological hollow scaffolds is an emerging area which has allowed the synthesis of inorganic materials with nanoscale dimensions.

Nanocontainers as Corrosion Inhibitors

2022
Metal corrosion is an electrochemical degradation process whose consequences adversely impact the structural integrities of material structures upon interaction with different environments. To reduce this scourge, recent developments in coating designs have incorporated additives capable of providing stimulus-responsive functionalities toward self ...

Nanocontainer-based corrosion sensing coating

Nanotechnology, 2013
The present paper reports on the development of new sensing active coating on the basis of nanocontainers containing pH-indicating agent. The coating is able to detect active corrosion processes on different metallic substrates. The corrosion detection functionality based on the local colour change in active cathodic zones results from the interaction ...

Active Anticorrosion Coatings with Halloysite Nanocontainers

The Journal of Physical Chemistry C, 2008
This work contributes to the development of a new generation of active corrosion protection coatings composed of hybrid sol−gel films doped with halloysite nanotubes able to release entrapped corrosion inhibitors in a controllable way. A silica-zirconia-based hybrid film was used in this work as an anticorrosion coating deposited on 2024 aluminum alloy.

Silica nanocontainers for active corrosion protection

Nanoscale, 2012
Novel self-healing protective coatings with nanocontainers of corrosion inhibitors open new opportunities for long-term anticorrosion protection of different metallic materials. In this paper a new type of functional nanoreservoir based on silica nanocapsules (SiNC) synthesized and loaded with corrosion inhibitor 2-mercaptobenzothiazole (MBT) in a one ...

Halloysite Tubes as Nanocontainers for Anticorrosion Coating with Benzotriazole

ACS Applied Materials & Interfaces, 2009
Halloysite clay nanotubes were investigated as a tubular container for the corrosion inhibitor benzotriazole. Halloysite is a naturally occurring cylindrical clay mineral with an internal diameter in the nanometer range and a length up to several micrometers, yielding a high-aspect-ratio hollow tube structure.
