A bio-based epoxy derived from dehydroabietylamine was synthesized. In comparison, its petrochemical counterpart based on benzylamine was also prepared. Their chemical structures were confirmed in detail by Fourier Transform Infrared Spectra (FT-IR) and Nuclear Magnetic Resonance (1H-NMR and HSQC). The curing reaction…
The discharge of oily wastewaters in the environment is steadily increasing, causing serious damages. Among various treatment methods, adsorption is generally considered the most appropriate, since it can remove both organic and inorganic pollutants. Adsorption using low-cost alternative biopolymers for removal of con…
We report the direct synthesis of highly luminescent Cu–Zn–In–S (CZIS) quaternary nanocrystals (NCs) in the non-coordinating solvent 1-octadecene (ODE) using chloride salts of Cu, In, and Zn as metal precursors in the presence of oleic acid and dodecanethiol. The resulting CZIS NCs had a narrow size distribution with…
Metallic nanoparticles have diverse applications in biomedicine, as diagnostics, image contrast agents, nanosensors and drug delivery systems. Anisotropic metallic nanoparticles possess potential applications in cell imaging and therapy + diagnostics (theranostics), but controlled synthesis and growth of these anisotr…
Through the discovery of ligand protected metal clusters with cores of a precise number of atoms, the exploration of the third dimension of the periodic table for fundamental research and also for applications has become less remote. So far, the exact number of metal atoms in the core has been determined unambiguously…
Carbon nanoparticle supported Au nanoparticles could be synthesized starting with a Au nanoparticle-chitosan composite. The composite nanoparticles efficiently converted phenylboronic acid to biphenyl through homocoupling.
Earth‐abundant iron pyrite (FeS 2 ) nanocrystals show great potential in broad photosensing applications due to their high photoabsorption coefficient (>10 5 cm −1 ) and ideal bandgap (0.95 eV). However, broad spectral photodetectors using the FeS 2 nanojunctions and external stimuli‐driven photoresponse have not b…
The identification of physicochemical factors that govern toxic effects of nanomaterials (NMs) is important for the safe design and synthesis of NMs. The release of metal cations from NMs in cell culture medium and the role of the metal cations in cytotoxicity are still under dispute. Here, we report that removal of N…
Water-glycerol solutions confined in 21 Å pores of the silica matrix MCM-41 C10 have been studied using differential scanning calorimetry (DSC) and broadband dielectric spectroscopy (BDS). The results suggest a micro-phase separation caused by the confinement. Likely the water molecules coordinate to the hydroxyl surf…
This study describes the use of mixtures of the ionic liquid (IL) trimethyl-sulfonium bis[(trifluoromethyl)sulfonyl]imide (Me3STFSI) and propylene carbonate (PC) as electrolytes for carbon-based electrochemical double layer capacitors (EDLCs). Two different mixtures have been investigated. The first one contained the…
Herein we report on the synthesis, characterization and catalytic application of metallasiloxanes of group 13-15. Reactions of R(Me)Si(OH)2 (R = N(SiMe3)-2,6-iPr2C6H3) (A) with Bi(NEt2)3, Sb(NEt2)3, Ge[N(SiMe3)2]2 and AlMe3 afforded [R(Me)SiO2BiNEt2]2 (1), [R(Me)SiO2SbOSi(OH)(Me)R]2 (2), [R(Me)SiO2]3(GeH)2 (3), and [R…
A large and diverse library of trans-A2B2 and A2BC-porphyrins possessing two arylethynyl substituents at the meso positions has been efficiently synthesized and tested for their two-photon absorption (2PA) behavior. All compounds fall into three general types A–π–A, D–π–D or D–π–A, where A is an electron-acceptor and…
Superparamagnetic iron oxide nanoparticles (SPION) are potential drug carriers and a magnetic resonance imaging (MRI) contrast agent for cancer therapy and diagnosis. In this study, dechlorinated cisplatin (CMDP) is tethered to maghemite nanoparticles modified with 4-oxo-4-(3-(triethoxysilyl)propylamino)butanoic acid…
Ti is introduced as a dopant during the atomic layer deposition (ALD) growth of ZnO for use as a transparent electrode. ALD-grown Ti-doped ZnO (TZO) films are deposited via alternate stacking of ZnO and TiOx atomic-doping layers. Their growth behavior, structural, electrical and optical properties are investigated. Ma…
Magnetic amphiphilic nanocomposites (MANCs) based on nanoalumina and carbon nanostructures were produced and applied as catalysts for biphasic reactions. These amphiphilic composites (MANCs) exhibit an excellent interaction at the interface of systems composed of immiscible liquids and can form stable emulsions betwee…
The first examples of lanthanide corroles are prepared by two synthetic routes. (Mes2(p-OMePh)corrole)La·4.5DME (1·4.5DME) and (Mes2(p-OMePh)corrole)Tb·4DME (2·4DME) are prepared from the free base corrole and Ln((NSiMe3)2)3, while (Mes2(p-OMePh)corrole)Gd·TACNMe3 (3·TACNMe3) is prepared by metathesis of the recently…
Transient bridges of DNA have been used to direct the self assembly of microscopic spherical particles into a variety of crystal structures. Here, by selectively reprogramming the strength of the DNA interactions within such crystals we form colloidal clusters with well-defined valence and symmetry at high yield. We f…
A cholesterol-functionalized gold(i)-isocyanide complex exhibiting mechanochromic luminescence properties was self-organized into distinct microscopic structures with different photoluminescence properties through vapor-diffusion of a poor solvent into its dichloromethane solution. The structure-optical property relat…
Hollow microcapsules capable of disintegrating in response to dual biological stimuli have been synthesized from two FDA approved drug molecules. The capsules fabricated from protamine and chondroitin sulphate disintegrate in the presence of either trypsin or hyaluronidase enzymes, which are documented to be simultane…
A novel selenadiazole-fused pyrene derivative PySe was successfully synthesized and characterized. Its single structure is almost planar and adopts a sandwich-herringbone packing model. The self-assembly behaviors based on compound PySe and its analogue thiadiazole-fused pyrene derivative PyS were studied in detail an…
