Our world is ever growing, there will be higher demands on electricity, and fossil fuels cannot satisfy this demand without further harming the environment. Likewise, renewable energy sources such as solar and winds are still in their infancy and, when used alone, are not realistic solutions to meet this demand. Westi…
A strategy is presented for the synthesis of dual-modality and theranostic silica (SiO2) nanohybrids that exert excellent properties for drug delivery vehicles as well as optical and magnetic resonance imaging. SiO2 nanohybrids are composed of CuInS2/ZnS quantum dots and magnetite nanocrystals, with an outside SiO2 sh…
This paper presents a novel approach for de-agglomeration and surface functionalization of detonation nanodiamond at the same time in one pot. Various kinds of polymer chains (e.g., polystyrene, polymethyl methacrylate and polyglycidyl methacrylate) can be chemically grafted onto the de-agglomerated nanodiamond by the…
A series of unsymmetrical silicon(IV) phthalocyanines with a permethylated β-cyclodextrin unit and a sugar or a diamino moiety as the axial substituents have been prepared. These compounds are highly photocytotoxic with IC(50) values as low as 21 nM, which is ca. sevenfold lower than those of the symmetrical bis(cyclo…
Three polyoxometalate-based inorganic–organic hybrid compounds constructed from silver(I)-L (L = N,N′-bis-pyridin-2-ylmethylene-hydrazine) species and saturated Keggin type polyoxoanions, {[Ag3L3](PW12O40)(CH3CN)(DMF)2.5}n (1), [Ag4L3(CH3CN)4][Ag2L(CH3CN)3](PMo12O40)2·CH3CN (2) and [(SiMo12O40){Ag2L(CH3CN)3}2]·(CH3CN)…
Cathodoluminescence (CL) characteristics and electron-beam induced surface chemical changes in nanocrystalline Tb3+ doped LiAl5O8 powder phosphors are presented. Bluish-white CL with a maximum at ∼543 nm was observed when the powders were irradiated with a 2 keV electron beam. The emissions in the green and the blue r…
Electrodeposition has been shown to be a promising method for the manufacturing of 3D current collectors and the coating of these with active electrode material as well as electrolytes usable for microbatteries. Within the next few years more work on the electrodeposition of cathode materials onto 3D current collector…
Structure tailoring of hybrid nanoparticles is highly desirable for a number of applications, due to their controllable physical properties. Here, a family of Ag–Fe3O4 nanohybrids is synthesized via a simple one-step reaction of silver acetate and iron acetylacetonate in the presence of 1,2-dodecanediol, oleylamine an…
There are very few methods to investigate how nanoparticles (NPs) are taken up and processed by cells in the organism in the short and long terms. We propose a nanomagnetism approach, in combination with electron microscopy, to document the magnetic outcome of iron oxide-based P904 NPs injected intravenously into mice…
The stoichiometric reactions of 2-(2,6-R-phenylimino)quinolin-8-ol (L1-L5, L1: R = Me, L2: R = Et, L3: R = (i)Pr, L4: R = Cl, L5: R = F) with Me(3)Al afforded the dimeric aluminium complexes [Me(2)AlL](2) (1-5) in good yields. By contrast, stoichiometric reactions of 2-(1-(2,6-R-phenylimino)propyl) quinolin-8-ol (L6-L…
We report the synthesis and characterization of a self-organized graphene–carbon nanotube (CNT) hybrid film consisting of multilayer graphene (MLG) supported by vertical CNTs on a Si substrate. The hybrid film shows an interesting structure of graphene in connecting to vertical CNTs while maintaining ohmic contact at…
The effect of Pt metal thickness on the hydrogen sensing sensitivity of Pt-coated, multi-layered graphene grown by chemical vapor deposition on Si-polar 4H-SiC, was investigated. As-grown graphene samples and graphene samples coated with 1 or 4 nm thick Pt films were used in this study. Compared to graphene without pl…
Non-close packed two-dimensional arrays of hydrogel microspheres with exceptional long range order are fabricated by exploiting the remarkable properties of hydrogels such as tunable solubility and self-healing. By addition of alcohol hydrogel microspheres self-assemble at the air/liquid interface into highly crystall…
Armchair graphene nanoribbons and their derived structures containing Stone-Wales defects are investigated using a self-consistent field crystal orbital method based on density functional theory. The investigation indicates that both the nanoribbons and the defective structures are semiconductors. A low concentration…
Mixtures containing ammonia-borane and sec-butylamine-borane remain liquid throughout the hydrogen release process that affords tri(N-sec-butyl)borazine and polyborazylene. Concentrated solutions with metal catalysts afford >5 wt% H(2) in 1 h at 80 °C and addition of (EMIM)EtSO(4) ionic liquid co-solvent eliminates co…
A novel, ultrasensitive, selective and flexible sensor strip based on polyaniline/polyamide-6 (PANI/PA-6) nano-fiber/net (NFN) membranes for naked-eye colorimetric detection of Cu2+ ions in water is successfully prepared by a facile electro-spinning/netting (ESN) process. The sensing mechanism involves the transformat…
Single-walled carbon nanotubes (SWCNTs) and inorganic fullerene-like WS2 nanoparticles were successfully dispersed in poly(ether ether ketone) (PEEK) by advantageously traditional melt processing techniques. This strategy offers an attractive way to combine the merits of organic and inorganic materials into novel hybr…
Cadmium selenide quantum dots (QDs) have been dispersed in a discotic liquid crystal columnar matrix. Thermophysical properties of these liquid crystal nanocomposites were investigated by UV-Vis spectroscopy, photoluminescence spectroscopy, differential scanning calorimetry, polarizing optical microscopy, DC conductiv…
Slow relaxation of the magnetization and hysteresis loop were observed in the antiferromagnetic ordered phase of a two-dimensional framework based on one-dimensional Co(II) magnetic chains.
We report, for the first time, colloidal synthesis of quinary CuIn1−xGax(SySe1−y)2 (CIGSSe) nanocrystals across the entire composition range (x,y) = 0 to 1 with band gaps tunable in the range of 0.98 to 2.40 eV by facile chemical synthesis. As a proof-of-concept, thin-film solar cells made by using the CIGSSe nanocrys…
