Atomic layer deposition, formerly called atomic layer epitaxy, was developed in the 1970s to meet the needs of producing high-quality, large-area fl at displays with perfect structure and process controllability. Nowadays, creating nanomaterials and producing nanostructures with structural perfection is an important g…
The ring-opening polymerization of cyclic carbonate monomers derived from biomass feedstocks constitutes an attractive way to prepare polycarbonates that are potentially useful as high-tech materials or commodity “bioplastics”. This process can be catalyzed by inherently different systems ranging from simple basic org…
In this work, we developed a novel flexible nanoporous carbon nanotube film to use as a binder-free and current collector-free anode electrode for lithium ion batteries, providing a new approach to flexible energy devices. The proposed novel anode configuration shows better cycling performance and rate capability than…
Photocatalytic hydrogen evolution with 2-phenyl-4-(1-naphthyl)quinolinium ion (QuPh+–NA) as a photocatalyst and dihydronicotinamide adenine dinucleotide (NADH) as a sacrificial electron donor has been made possible for the first time by using nickel nanoparticles (NiNPs) as a non-precious metal catalyst. The hydrogen…
Metal–organic materials that are constructed from polyhedral supermolecular building blocks, SBBs, can offer exquisite control over structure and afford useful features such as multiple cage types and relatively narrow pores. This contribution describes how a custom-designed porphyrin, tdcpp, self-assembles with M(II)…
Two isostructural 2D → 2D parallel → 3D inclined interpenetrating polycatenane-like metal-organic frameworks were successfully constructed based on length-adjusted tricarboxylate ligands. With the merit of being microporous, IFMC-10 can serve as host for encapsulating lanthanide cations and I(2) to exhibit luminescent…
AgI is instable under light irradiation owing to its photosensitive properties, while a supported Ag-AgI composite has been demonstrated to be a stable photocatalyst. However, seldom investigations have been focused on the photocatalytic activity (including deactivation) and photoinduced stability of the photosensitiv…
A π-conjugated polyazine containing diketopyrrolopyrrole (DPP) moiety, PDBTAZ, is synthesized through a simple condensation polymerization. PDBTAZ is found to be a high-performance ambipolar semiconductor in organic thin film transistors (OTFTs), showing an electron mobility of up to 0.41 cm(2) V(-1) s(-1) and a hole…
CO(2)-switchable gold nanoparticles (AuNPs) were prepared by functionalizing AuNPs with CO(2)-switchable polymers. Their dispersion-re-dispersion in and separation from aqueous solution can be easily and reproducibly adjusted by CO(2) bubbling through and removal from the solution, enabling unique CO(2) controllable,…
Immobilized metal affinity chromatography (IMAC) is a powerful method in phosphopeptide enrichment. However, the achievement of highly specific enrichment and sensitive detection of phosphopeptide by IMAC is still a big challenge because of the lack of high specificity and large binding capacity of conventional IMAC m…
Semiconductor based nanocomposites are quite promising in the areas of photocatalysis and photovoltaics due to their efficient charge separation. Herein, we demonstrated a simple and green one-step method to prepare novel Cd0.5Zn0.5S/TNTs (titanate nanotubes) nanocomposites with low-priced metallic elements. Transmiss…
A new alternating copolymer of fluorene and naphthalene diimide, PF-NDI, was synthesized and characterized. The highest power conversion efficiency of all-polymer solar cells based on P3HT:PF-NDI reached 1.63% with a relatively high fill factor of 0.66 by using 1,8-diiodooctane as a solvent additive to optimize the mi…
Three phosphorescent Ir and Ru complexes containing dicarboxylate functional groups have been doped into the framework of Zr6O4(OH)4(bpdc)6 (UiO-67, bpdc = para-biphenyldicarboxylate) to yield stable metal–organic frameworks (MOFs 1–3) which are highly porous with BET surface areas of 2568, 2292, and 1277 m2 g−1, resp…
We report synthesis of hollow calcium phosphate (CaP) nanospheres with high surface area by using block copolymer micelles as templates. The obtained CaP nanospheres exhibit very high biocompatibility, showing great promise for intracellular bio-applications in future.
A simple and inexpensive method to form a hematite photoanode for efficient water oxidation is reported. A very thin ZnO overlayer was deposited on top of a thin film of hematite and found, compared with non-treated hematite, to increase the photocurrent and reduce the onset potential for generating oxygen from water.…
Uniformly sized superparamagnetic single-shell nonporous (S1) and double-shell mesoporous silica nanocomposite particles with ∼130 nm magnetite cluster cores are synthesised in this study. Mesoporous particles are prepared with two BJH pore sizes (2.44 and 3.76 nm, designated as S2 and S3 particles, respectively). Onc…
Monodispersed silica-coated ZnO nanoparticles were successfully synthesized and modified with hydrophilic amino groups on the surfaces. The emission colour of the as-prepared ZnO nanoparticles could be tuned by adjusting the reactant ratio and the reaction time. The resulting particles were stable in water, phosphate…
Efficient luminescence was realized by suppressing not only excited-state distortion but also C-H vibrational quenching in a Cu complex. Organic light-emitting diodes containing the Cu complex as an emitting dopant exhibited a maximum external quantum efficiency of 7.4%.
CdSe and CdSe/CdS quantum dots (QDs) with narrow size distribution are attached onto TiO2 electrodes by linker-assisted chemical bath deposition (LACBD). Preparation is carried out at 60 °C or 160 °C, which results in the formation of CdSe or CdSe/CdS QDs onto the TiO2 nanoparticles connected by thioglycolic acid (TGA…
The new Al-based metal-organic framework [Al(13)(OH)(27)(H(2)O)(6)(BDC-NH(2))(3)Cl(6)(C(3)H(7)OH)(6)] denoted CAU-6 (CAU = Christian-Albrechts-Universität) was solvothermally synthesized in 2-propanol and was thoroughly characterized. The framework structure exhibits a unique column-shaped inorganic building unit, whi…
