Small-angle X-ray scattering (SAXS) was performed on dispersions of ultrasmall (d < 10 nm) fluorescent organic-inorganic hybrid core-shell silica nanoparticles synthesized in aqueous solutions (C′ dots) by using an oscillating flow cell to overcome

We report a method for tuning the domain spacing (Dsp) of self-assembled block copolymer thin films of poly(styrene-block-methyl methacrylate) (PS-b-PMMA) over a large range of lamellar periods. By modifying the molecular weight distribution (MWD) sh

While patterning the nucleation of crystalline inorganics at the nanometer length scale via low temperature, aqueous growth methods is highly desirable, it remains synthetically challenging. We report a generalizable approach for fabricating crystall

Despite advances in nanomaterials synthesis, the bottom-up preparation of nanopatterned films as templates for spatially confined surface reactions remains a challenge. We report an approach to fabricating nanoscale thin film surface structures with

We report herein the modular synthesis and nanolithographic potential of poly(dimethylsiloxane-block-methyl methacrylate) (PDMS-b-PMMA) with self-assembled domains approaching sub-10 nm periods. A straightforward and modular coupling strategy, optimi

A new family of polymer electrolytes based on a poly(allyl glycidyl ether) (PAGE) platform has been developed that overcomes many of the limitations of poly(ethylene oxide) (PEO) for battery electrolyte applications. PAGE was shown to have peak condu

UV–visible spectra of heteropolyacids (HPAs) in solution were measured as a simple method of correlating and predicting the redox properties of HPAs. The range of Keggin-type HPAs included H3PMo12O40, H3PW12O40, and variations of cations, heteroato

UV-visible spectroscopic studies of solid H3PMo12O40were carried out to elucidate the effect of crystalline water molecules, and in turn, to provide a guideline for utilizing UV-visible spectra of solids to probe reduction potentials of HPA catalysts

UV–vis spectra of solid state H 3 PMo 12− x W x O 40 ( x = 0, 3, 6, 9, 12) catalysts were obtained to elucidate the effect of crystalline water molecules and to explore the reduction potentials of the heteropolyacid (HPA) catalysts. The UV–vis
