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…
The electro-deposition and dissolution of MnO 2 is studied for its potential utilization in hybrid supercapacitors.A commercially available graphene powder is used as high surface area substrate and capacitive type electrode.An aqueous electrolyte composed of 0.5 M H 2 SO 4 + 0.5 M MnSO 4 is used.The deposition-dissol…
A new method is introduced to facilely and greenly prepared a coating with functional groups on the surface of aramide fibers through a polymerization using horseradish peroxidase as the catalyst. The chemical and morphological structures of the poly(glycidyl methacrylate) (PGMA) coated aramide fibers (PGMA@KF) were s…

Poor water-solubility and biocompatibility are the biggest obstacles for the bioapplications of upconversion nanophosphors (UCNPs). In this work, a facile solvothermal approach was developed for the one-pot synthesis of monodisperse and water-soluble β-NaYF4 UCNPs by employing poly(acrylic acid, sodium salt) (PAAs) as…
The properties of atactic short-chain polystyrene films confined between two parallel gold surfaces at a temperature of 503 K are investigated using a combination of density functional theory calculations and classical atomistic simulations. A classical Morse-type potential, used to describe the interaction between th…
To explore the synergistic effects of polyoxometalate and noble metal nanoparticles on the photovoltaic performance of titanium dioxide (TiO2), multilayer film photoanodes consisting of TiO2 nanoparticles, gold nanoparticles (Au) and Dawson-type polyoxometalate K6P2W18O62 (abbr. as P2W18) have been prepared by the lay…
The room-temperature solid-state chemical reaction technique has been used to synthesize the silver nanoparticle-loaded semiconductor silver@silver chloride for the first time. It has the advantages of convenient operation, lower cost, less pollution, and mass production. This simple technique created a wide array of…
Upon UV irradiation of a bent-core liquid crystal (LC) bearing an azo linkage doped with chiral molecules, a photo-induced transition takes place from BPI to BPIII. BPIII is stabilised over 20 °C, while the widening of the BPI range is not so remarkable. The mechanism of photo-induced BPI–BPIII transition is also disc…
4–5 nm nanodiamonds tend to self-assemble into 100–200 nm nanodiamond aggregations and furthermore nanodiamonds in the early stages of the detonation process present fantastic twinned morphologies, indicating that there are strong interactions among these nanodiamonds. Herein, electrostatic interactions and van der Wa…
