A precursor film has been fabricated from TGA (thiolglycolic acid)-stabilized CdTe nanoparticles and NDR (nitro-containing diazoresin) using electrostatic interactions and the standard layer-by-layer assembly method; covalent bonds are formed under ultraviolet irradiation. XPS provided evidence for the presence of CdTe nanoparticles within the polymer ultrathin films. UV-visible spectroscopy an...
In situ synchrotron x-ray diffraction studies of the nucleation of barium fluoride from supersaturated solutions, at fatty-acid monolayer templates, reveal a commensurate relationship between the interfacial lattices of the organic molecules and the inorganic atoms. At the onset of growth, the barium fluoride layer is very thin and the lateral unit cell is contracted by as much as 4%; at the sa...
The use of an inorganic perrhenate ligand in the structure of early-transition-metal alkoxide precursors permits to achieve uniform self-assembly of the primary nanoparticles produced by their hydrolysis. The latter has been carried out in a hydrocarbon reaction medium by the addition of water with vigorous stirring, either in the pure form or in solutions in parent alcohols. The self-assembly ...
A series of novel Si-O-Si crosslinked organic/inorganic hybrid semi-crystalline polymers with shape memory properties was prepared from alkoxysilane-terminated poly(butylene succinate) (PBS) by water-induced silane crosslinking under organic solvent-free and catalyst-free conditions. The hydrolyzation and condensation of alkoxysilane end groups allowed for the generation of silica-like crosslin...
A conventional and general route has been exploited to the high yield synthesis of many kinds of highly crystalline metal oxide and mixed oxide nanocrystals with different morphologies including belt, rod, truncated-octahedron, cubic, sphere, sheet via the hydrothermal reaction of inorganic precursors in aqueous solution in the presence of bifunctional 6-aminohexanoic acid (AHA) molecules as a ...
Vacuum-deposited perovskites provide a more direct path to manufacturing large area solar cells because of ready compatibility with multilayered architectures and historic use in the electronics industry. However, vacuum compatible co-deposition organic-inorganic remains difficult due issues precisely controlling organic precursor flux. Here, we demonstrate prototype specifically designed for c...
Current methods of estimating the public health effects of emissions are computationally too expensive or do not fully address complex atmospheric processes, frequently limiting their applications to policy research. Using a reduced-form model derived from tagged chemical transport model (CTM) simulations, we present PM2.5 mortality costs per tonne of inorganic air pollutants with the 36 km × 3...
Highlights 21 • Method brings results from detailed chemical transport models to policy analysis. 22 • Method estimates marginal social cost and intake fraction accurately and quickly. 23 • Reduced-form models produce errors comparable to state-of-the-art models' 24 errors. Abstract 26 It is challenging to estimate the public health costs of fine particulate matter (PM 2.5) and 27 its precursor...
New organic-inorganic polyurethane-based hybrids with enhanced mechanical properties and thermal insulation are reported. Polyurethane-based characterized by the intimate interactions of their inorganic organic co-networks prepared sol-gel approach, have exhibited exceeding those polyurethane foams, e.g. stability, durability insulating effectiveness. However, previously been poor. Here, new po...
