A facile method to fabricate copper oxide functionalized silver nanowires with high sensitivity to biomolecules is reported for the first time. The enhanced surface roughness of silver nanowire and the molecule capture capability of copper oxide nanoparticles account for the high sensitivity of this nanocomposite.
We experimentally study the shear flow of oil-in-water emulsion droplets in a thin sample chamber with a hopper shape. In this thin chamber, the droplets are quasi-2D in shape. The sample is at an area fraction above jamming and forced to flow with a constant flux rate. Stresses applied to a droplet from its neighbors…
Guided tissue regeneration (GTR) is a widely used method in periodontal therapy, which involves the placement of a barrier membrane to exclude migration of epithelium and ensure repopulation of periodontal ligament cells. The objective of this study is to prepare and evaluate a new type of soluble eggshell membrane pr…
Active species, product distributions and a suggested catalytic cycle are reported for the dehydrocoupling of the phosphine-borane H(3)B·P(t)Bu(2)H to give HP(t)Bu(2)BH(2)P(t)Bu(2)BH(3) using the [Rh(COD)(2)][BAr(F)(4)] pre-catalyst.
In this study, gold-nanoparticle-crosslinked Pluronic micelles were synthesized and used as a carrier for paclitaxel (PTX). The resultant PTX-loaded gold-nanoparticle-crosslinked Pluronic micelles were about 69 nm in diameter. Physical stability and in vivo pharmacokinetic studies revealed that these micelles were mor…
In the present work, we show that metallic Ti thin films on FTO glass can be completely anodized to a mesoporous oxide layer using a glycerol–K2HPO4 electrolyte at elevated temperatures (∼180 °C). This results in highly transparent mesoporous oxide coated electrodes that provide a significantly enhanced transparency c…
A series of novel 1-D double-chain organic–inorganic hybrid polyoxotungstates [Cu(dap)2(H2O)]2{Cu(dap)2[α-H2SiW11O39Ln(H2O)3]2}·xH2O [Ln = CeIII, x = 9 (1); Ln = PrIII, x = 10 (2), Ln = NdIII, x = 10 (3), Ln = SmIII, x = 10 (4), Ln = EuIII, x = 10 (5), Ln = GdIII, x = 9 (6), Ln = TbIII, x = 8 (7), Ln = DyIII, x = 8 (8…
Organocatalytic ring opening polymerization (OROP) is used to effect the rapid, scalable, room temperature formation of size-controlled, highly uniform, polyvalent, nanogel star polymer nanoparticles of biodegradable composition.
We report large-scale synthesis of high surface area nano-oxides of Ce0.8M0.2O2/Al2O3 (M = Tb and Hf) possessing cuboctahedral shape of 3–5 nm size, which exhibit excellent oxygen storage capacity (OSC) and superior CO oxidation activity in comparison to the most advanced ceria–zirconia/alumina catalyst supports emplo…
Ligand exchange reactions on size-selected Au(38)(2-PET)(24) and Au(40)(2-PET)(24) clusters (2-PET: 2-phenylethylthiol) with mono- and bi-dentate chiral thiols were performed. The reactions were monitored with MALDI mass spectrometry and the arising chiroptical properties were compared to the number of incorporated ch…
By taking anodic aluminum oxide membranes as the starting materials and selectively removing the outer layers from the unit cells of anodic aluminum oxide membranes after a proper hydrothermal treatment, highly ordered porous α-alumina ceramic membranes are fabricated successfully. This fabrication method might be a n…
Fluorescent core–shell nanohybrids with the shells derived from carbon dots and cores differing in the chemical nature and morphology were synthesized. Hybrid nanoparticles combine fluorescence with other functionalities such as magnetic response on a single platform. These hybrids can be used in various bioapplicatio…
A facile synthesis of polymer-inorganic hybrid hollow mesoporous nanospheres was developed based on the entrapment of a dissolved polymer core template in the framework during the assembly process of the hybrid hollow nanospheres for efficient and size-selective enrichment of target peptides/proteins from complex bios…
Here we demonstrated a simple low-cost approach to dramatically increase the power density of solid oxide fuel cells (SOFCs) using an improved anode functional layer (AFL) structure. By infiltrating a very small amount (∼2 wt%) of Ni and Gd0.1Ce0.9O1.95(GDC) precursor solution into a submicron-sized, colloidally depos…
A diagram of energies between the HOMO of donor (D) and LUMO of acceptor (A) vs.ΔE(1/2)(DA) (= E(1/2)(D) - E(1/2)(A): E(1/2) = first-redox potential) clearly demonstrates the ionicity in the series of D/A assemblies, [{Ru(2)(CF(3)CO(2))(4)}(2)(TCNQR(x))]·n(solv) (TCNQR(x) = 2,5- or 2,3,5,6-R-substituted 7,7,8,8-tetrac…
Polymer electrolytes comprised of silicotungstic acid (SiWA) in cross-linked polyvinyl alcohol have been developed and characterized for ultra-high rate electrochemical capacitors (ECs). The solid polymer electrolytes outperformed liquid H2SO4 electrolytes in a similar cell setup. The polymer electrolyte enabled thin…
The fabrication of black and electrically conducting films on glass substrate derived from covalently functionalized reduced graphene oxide (FRGO) has been reported in this work. Graphene oxide (GO) was first prepared following the Hummers method and then functionalized using an organically modified silicon alkoxide,…
Adamantane-based microporous polymers were prepared by Friedel–Crafts reaction of 1-bromoadamantane with benzene, biphenyl and terphenyl and then post-functionalized with 4-nitrobenzoyl chloride. At 298 K, the CO2 uptake capacity of the functionalized polymers was increased by 18–25%, owing to the interaction between…
Phthalazinone rigid-rod networks with excellent thermostability have been prepared by the polyaddition of an unsymmetrical phthalonitrile-functional phthalazinone, namely 4-(4-(4-(3,4-dicyanophenoxy)phenyl)-1-oxophthalazin-2(1H)-yl)phthalonitrile (5) in the presence of promoting agents. 5 was readily prepared via nucl…
