Luminescent ZnO quantum dots (QDs) have been prepared, and the fluorescence intensity of the QDs can be increased greatly with the introduction of carbon nanodots, while the fluorescence lifetime of the QDs decreases significantly. The fluorescence enhancement and lifetime decrement can be attributed to the surface pl…
CaCu <sub>3</sub> Ti <sub>4</sub> O <sub>12</sub> (CCTO)–polyaniline (PANI) nanofiber composites with different ratios of PANI/CCTO were successfully prepared by <italic>in situ</italic> polymerization and were shown to be active photocatalysts under irradiation with visible light.
Graphene oxide (GO) was explored as an atomically-thin transferable seed layer for the atomic layer deposition (ALD) of dielectric materials on any substrate of choice. This approach does not require specific chemical groups on the target surface to initiate ALD. This establishes GO as a unique interface which enables…
New mercaptophosphonic linkers are presented for the attachment of ternary quantum dots to ZnO and TiO2 for photovoltaic applications.
Two new two-dimensional homometallic compounds {[M2(bpm)(ox)2]n·5nH2O} with M = Co(II) (1) and Zn(II) (2) and the mononuclear nickel(II) complex [Ni(bpm)2(ox)]·2H2O (3) [bpm = 2,2'-bipyrimidine and ox = oxalate] have been prepared and structurally characterized. 1 and 2 are isostructural compounds whose structures are…
Highly ordered lamellar grains were produced by thermal treatment of the samples in a rapid thermal processing machine. The processing parameters that maximize the lateral order avoiding any degradation of the macromolecules were identified.
An organic–inorganic hybrid compound comprised of a Zn/Al layered double hydroxide (LDH) intercalated with citric acid (LDH–CA) was dispersed in polyimide (PI) with an <italic>N</italic> -benzonitrile side group, through <italic>in situ</italic> polymerization.
Controlled loading of <italic>in situ</italic> silica in NR/CR blend by solution sol–gel method for enhancing the reinforcement.
Through the bridging effect of CNTs, the fracture toughness of the immiscible PLLA/EVA blend was greatly improved.
A novel flexible alloy substrate (Phynox, 50 μm thick) was used for the synthesis of zinc oxide (ZnO) nanorods <italic>via</italic> a low-temperature solution growth method.
Plug-flow crystallization (PFC) is a promising continuous pharmaceutical crystallization process but is prone to fouling due to uncontrolled crystallization on the reactor surface (encrustation). This results in operational issues such as (1) flow blockage, (2) increased thermal resistance, and (3) reduced supersatura…
Oxidation is a major cause for the degradation of materials including graphene, where epoxidation (forming the C-O-C bond) is very common. In addition, graphene oxide, in which the epoxy group is one of the two major functional groups (the other is hydroxy), is an important precursor material used for the bulk synthes…
In this study, four boron ketoiminate-based conjugated polymers <bold>P1–P4</bold> are designed and synthesized <italic>via</italic> Suzuki polymerization.
Silicon nanocrystals functionalized with tetraphenylporphyrin Zn(II) chromophores at the periphery perform as light harvesting antennae: excitation of the porphyrin units in the visible spectral region yields sensitized emission of the silicon nanocrystal core in the near infrared with a long lifetime (λ(max) = 905 nm…
The integration reliability of mechanically robust, ultra low- <italic>k</italic> spin-on-glass poly(methyl)silsesquioxanes incorporating incompletely condensed methyl-POSS were examined for next generation microelectronics.
Synergy effect of CaCl <sub>2</sub> and Na <sub>2</sub> EDTA on the structure and morphology control of α-HH by regulating G/W.
In this work, we investigated the enhancement of the electro-optic response by introducing electron-rich heteroatoms as additional donors into the donor or bridge of a conventional second-order nonlinear optical chromophore. A series of chromophores C2-C4 based on the same tricyanofuran acceptor (TCF) but with differe…
Three-electron reduction of hexaazatrinaphthylene (HAN) with a magnesium(I) reagent leads to [(HAN){Mg(nacnac)}3] (1), containing a [HAN](3-) ligand with a spin of S = 1/2. Ab initio calculations reveal that the [HAN](3-) ligand in 1 has a ground-state wave function with multiconfigurational properties, and can be des…
First-principles plane-wave pseudopotential calculations have been performed to study the charge states and energetics of intrinsic point defects as vacancies, interstitials and antisite atoms in α-Al2O3, and thus a new perspective on the process of intrinsic point defects has been proposed. Considering the various ch…
The donor doping of Nb <sup>5+</sup> for Ti <sup>4+</sup> in the B sites of BaTiO <sub>3</sub> rapidly shifts the ferroelectric phase transition to a lower temperature and diffuses it, so that the electrocaloric Δ <italic>T</italic> <sub>max</sub> gradually reduces and the temperature window becomes much wider.
