Metal–Organic Framework Co-MOF-74-Based Host–Guest Composites for Resistive Gas Sensing
The tetrathiafulvalene (TTF)-infiltrated MOF, Co-MOF-74, has been prepared following the host–guest concept and evaluated in resistive gas sensing and exhibits an increased electrical conductivity which could be used for gas sensing. Expand
Localized Surface Plasmon Resonances of Various Nickel Sulfide Nanostructures and Au-Ni3S2 Core-Shell Nanoparticles
In this work, we investigate the occurrence of localized surface plasmon resonances (LSPRs) in different nickel sulfide nanostructures. Therefore, spherical and anisotropic nickel sulfideExpand
Hypericum perforatum L.-Mediated Green Synthesis of Silver Nanoparticles Exhibiting Antioxidant and Anticancer Activities
The AgNPs prepared in the present study have been shown to exhibit a high antioxidant activity for 2, 2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) radical cation, and super oxide anion radical and 2,2-diphenyl-1-picrylhydrazyl. Expand
Emission color-tunable oxazol(in)yl-substituted excited-state intramolecular proton transfer (ESIPT)-based luminophores.
Oxazolinyl- and arylchalcogenazolyl-substituted hydroxyfluorenes exhibiting excited-state intramolecular proton transfer (ESIPT) are described as potent and highly modular luminophores. EmissionExpand
Patterning of Nanoparticle-Based Aerogels and Xerogels by Inkjet Printing.
First spectro-electrochemical measurements are recorded to investigate the charge-carrier mobility within these 3D semiconductor-based xerogel networks, obtained by simultaneously printing semiconductor nanoparticles and a destabilization agent. Expand
Versatile route to core-shell reinforced network nanostructures.
By analyzing the local elemental distribution, the shells can be shown to be homogeneous over the macroscopic network monolith and can be used to considerably reinforce the mechanical strength of the final core-shell network structure. Expand
Nanocrystal Aerogels with Coupled or Decoupled Building Blocks
By thorough examination of the resulting optical properties of the generated structures, the clear correlation between nanoscopic/microscopic structure and macroscopic optical properties is demonstrated. Expand
Reversible cation exchange on macroscopic CdSe/CdS and CdS nanorod based gel networks.
It is shown that cation exchange reactions can also be transferred to macroscopic objects like aerogels or lyogels, which cannot be synthesized via direct destabilization of the respective colloidal solutions. Expand
A Versatile Route to Assemble Semiconductor Nanoparticles into Functional Aerogels by Means of Trivalent Cations.
The assembled nanoparticle network provides longer exciton lifetimes with retained photoluminescence quantum yields, that make these nanostructured materials a perfect platform for novel multifunctional 3D networks in sensing. Expand
Control over Structure and Properties in Nanocrystal Aerogels at the Nano-, Micro-, and Macroscale
The efforts undertaken in the structuring of nanocrystal-based network materials on different scales, fine-tuning of the individual building blocks on the nanoscale, the network connections on the microscale, and the macroscale structure and shape of the final construct are summarized. Expand
