Cerium-doped Titanium dioxide (TiO(2)) nanoparticles are prepared by sol-gel method. Doping shifts the UV absorption edge of TiO(2) to the visible region, making it efficient for visible light photocatalysis. Incorporation of cerium decreases the effective band gap of TiO(2) and increases the Urbach energy levels. At…
A series of dibromomaleimides have been shown to be very efficacious at insertion into peptidic disulfide bonds. This conjugation proceeds with a stoichiometric balance of reagents in buffered solutions in less than 15 min to give discrete products while maintaining the disulfide bridge and thus peptide conformation.…
Metal Oxide Nanostructures as Gas Sensing Devices explores the development of an integrated micro gas sensor that is based on advanced metal oxide nanostructures and is compatible with modern semiconductor fabrication technology. This sensor can then be used to create a compact, low-power, handheld device for analyzin…
Capsules in capsules: An emulsion–centrifugation method allows polymersomes in polymersomes “PiPs” (see picture) or polymer vesosomes to be prepared. This simple approach to generate biomimetic compartmentalized structures offers a way to encapsulate several different and even mutually incompatible active substances,…
A rapid, clean, and continuous hydrothermal route to the synthesis of ca. 14 nm indium oxide (In(2)O(3)) nanoparticles using a superheated water flow at 400 °C and 24.1 MPa as a crystallizing medium and reagent is described. Powder X-ray diffraction (XRD) of the particles revealed that they were highly crystalline des…
A facile one-step solution-based process to in situ synthesize SnO(2)/graphene (SG) nanocomposites was developed, by using the mixture of dimethyl sulfoxide (DMSO) and H(2)O as both solvent and reactant. The reduction of graphene oxide (GO) and the in situ formation of SnO(2) nanoparticles were realized in one step. T…
Silver nanoplates are introduced as a new photoacoustic contrast agent that can be easily functionalized for molecular photoacoustic imaging in vivo. Methods are described for synthesis, functionalization, and stabilization of silver nanoplates using biocompatible ("green") reagents. Directional antibody conjugation t…
The noncentrosymmetric half Heusler compound YPtBi exhibits superconductivity below a critical temperature ${T}_{c}=0.77$ K with a zero-temperature upper critical field ${H}_{c2}(0)=1.5$ T. Magnetoresistance and Hall measurements support theoretical predictions that this material is a topologically nontrivial semimeta…
Direct oxidation alkaline fuel cells (DOAFCs) possess particular advantages on the possibility of employing low cost non-noble metal catalysts. A wide range of fuels can be used due to superior reaction kinetics in alkaline media. The development of DOAFCs was hindered by the carbonation of electrolyte due to the pres…
Cellulose synthase (CESA) complexes can be observed by live-cell imaging to move with trajectories that parallel the underlying cortical microtubules. Here we report that CESA interactive protein 1 (CSI1) is a microtubule-associated protein that bridges CESA complexes and cortical microtubules. Simultaneous in vivo im…
Abstract Strategic combinations of affordable and scalable post‐synthetic modifications enabled to design a broad family of hierarchical Y and USY zeolites (FAU topology) independent on the Si/Al ratio. Pristine (Y, Si/Al = 2.4), steamed (USY, Si/Al = 2.6), and steamed and dealuminated (USY, Si/Al = 15 and 30) zeolite…
The catalytic activity of zeolitic imidazole framework-8 (ZIF-8) and amine-functionalized ZIF-8 catalysts in the synthesis of chloropropene carbonate from CO 2 and epichlorohydrin is demonstrated. In contrast to hitherto known catalysts, ZIF-8 catalysts displayed high epoxide conversions and moderate to high selectivi…
The mechanical properties of pristine graphene oxide paper and paper-like films of polyvinyl alcohol (PVA)-graphene oxide nanocomposite are investigated in a joint experimental-theoretical and computational study. In combination, these studies reveal a delicate relationship between the stiffness of these papers and th…
Abstract In this work, a novel hydrothermal route is developed to synthesize cobalt carbonate hydroxide, Co(CO 3 ) 0.5 (OH)·0.11H 2 O. In this method, sodium chloride salt is utilized to organize single‐crystalline nanowires into a chrysanthemum‐like hierarchical assembly. The morphological evolution process of this o…
Micrometre-scale polypyrrole (PPy) structures are synthesised for electrochemical supercapacitor applications by a facile electrochemical route. Globular polypyrrole microstructures of size <5 µm are grown on stainless steel (SS-304) substrate by electro-polymerisation of pyrrole on oxygen microbubble templates electr…
A thorough understanding of how electrons pass through point defects in carbon nanotubes is crucial for building carbon nanotube devices. We have generated point defects in the sidewalls of pristine carbon nanotubes via voltage pulses from a conducting atomic force microscope probe and studied the resulting changes in…
A recently developed theory of flag-graphs and k-orbit maps classifies maps according to their symmetry-type graphs.We propose a similar classification for polyhedra showing that Platonic and Archimedean solids with the same vertex pattern have isomorphic symmetry-type graphs and introducing some tools for the determi…
-methacrylic acid (EMAA) ionomers are incorporated into polyelectrolyte complexes and thin films fabricated with the layer-by-layer technique using mixed solvent systems of THF and water. EMAA ionomers have been reported to have self-healing properties. The thin films were optically clear and can be made as a coating…
We offer a novel approach to improve the performance of P3HT/TiO 2 hybrid photovoltaic devices by incorporating either hydroxyl- or amino-functionalized silica nanodots (SND–OH or SND–NH 2 ) into the hole transport layer of the PEDOT:PSS. The SNDs serve as screens between conducting polymer and ionomer PSS to improve…
Abstract The network polysilanes (polysilynes) [RMe2SiCH2CH2Si]n, [R=Ph (1), 2‐Furyl (2)] have been synthesized by room temperature reaction of the corresponding organotrichlorosilane with Na dispersion in tetrahydrofuran (THF) medium. The method allows the formation of high molecular weight polymers [Mw/PDI = 10,504/…
