Transfer of Inorganic-Capped Nanocrystals into Aqueous Media.

The journal of physical chemistry letters

Guhrenz C, Sayevich V, Weigert F, Hollinger E, Reichhelm A, Resch-Genger U, Gaponik N, Eychmüller A.
PMID: 29083902
J Phys Chem Lett. 2017 Nov 16;8(22):5573-5578. doi: 10.1021/acs.jpclett.7b02319. Epub 2017 Nov 02.

We report on a novel and simple approach to surface ligand design of CdSe-based nanocrystals (NCs) with biocompatible, heterobifunctional polyethylene glycol (PEG) molecules. This method provides high transfer yields of the NCs into aqueous media with preservation of the...

Unusual ultra-hydrophilic, porous carbon cuboids for atmospheric-water capture.

Angewandte Chemie (International ed. in English)

Hao GP, Mondin G, Zheng Z, Biemelt T, Klosz S, Schubel R, Eychmüller A, Kaskel S.
PMID: 25522081

There is significant interest in high-performance materials that can directly and efficiently capture water vapor, particularly from air. Herein, we report a class of novel porous carbon cuboids with unusual ultra-hydrophilic properties, over which the synergistic effects between surface...

Colloidal Nanocrystals Embedded in Macrocrystals: Methods and Applications.

The journal of physical chemistry letters

Adam M, Gaponik N, Eychmüller A, Erdem T, Soran-Erdem Z, Demir HV.

J Phys Chem Lett. 2016 Oct 20;7(20):4117-4123. doi: 10.1021/acs.jpclett.6b01699. Epub 2016 Oct 04.

Colloidal semiconductor nanocrystals have gained substantial interest as spectrally tunable and bright fluorophores for color conversion and enrichment solids. However, they suffer from limitations in processing their solutions as well as efficiency degradation in solid films. As a remedy,...

Quantum-Dot-Based (Aero)gels: Control of the Optical Properties.

The journal of physical chemistry letters

Wolf A, Lesnyak V, Gaponik N, Eychmüller A.
PMID: 26295769
J Phys Chem Lett. 2012 Aug 16;3(16):2188-93. doi: 10.1021/jz300726n. Epub 2012 Jul 31.

In this work, we have developed novel hybrid quantum dot gels based on the controllable and reversible assembly of nanoparticles via metal-tetrazole complexation. Combining in one hybrid network nanocrystals of different semiconductors (ZnSe and CdTe) as well as quantum...

Nickel cobalt oxide hollow nanosponges as advanced electrocatalysts for the oxygen evolution reaction.

Chemical communications (Cambridge, England)

Zhu C, Wen D, Leubner S, Oschatz M, Liu W, Holzschuh M, Simon F, Kaskel S, Eychmüller A.
PMID: 25855058
Chem Commun (Camb). 2015 May 07;51(37):7851-4. doi: 10.1039/c5cc01558h.

A class of novel nickel cobalt oxide hollow nanosponges were synthesized through a sodium borohydride reduction strategy. Due to their porous and hollow nanostructures, and synergetic effects between their components, the optimized nickel cobalt oxide nanosponges exhibited excellent catalytic...

Designed fabrication of ordered porous au/ag nanostructured films for surface-enhanced Raman scattering substrates.

Langmuir. 2006 Mar 14;22(6):2605-9. doi: 10.1021/la052659u.

This article reports the designed preparation of two different kinds of novel porous metal nanostructured films, namely, an ordered macroporous Au/Ag nanostructured film and an ordered hollow Au/Ag nanostructured film. Different from previous reports, the presently proposed method can...

Essentially, the term aerogel describes a special geometric structure of matter. It is neither limited to any material nor to any synthesis procedure. Hence, the possible variety of materials and therefore the multitude of their applications are almost unbounded....
