Hydrogen-bonded photomobile liquid-crystalline polymer fibers with chemically modified single-walled carbon nanotubes were prepared and their photomobile properties were investigated.
The role of samarium (Sm) 4f states and Sm-perturbed O 2p states in determining the sulfur tolerance of Sm-doped CeO2 was elucidated by using the density functional theory (DFT) + U calculation. We find that the sulfur tolerance of Sm-doped CeO2 is closely related to the modification of O 2p states by the strong inter…
We report that the decoration of metallic single-walled carbon nanotube (m-SWCNT) networks with cobalt(ii) oxide (CoO) can improve the electrical conductivity of the networks. To measure the electrical conductivity, we prepared m-SWCNT networks between the source and drain electrodes of field-effect transistors (FETs)…
We determined the onset of thixotropy in hydrogels when two homologues of low-molecular-weight hydrogelators, <italic>N</italic> -alkyl- <sc>d</sc> -glucamides (CnNG), were mixed.
Polycarbazole chains form loops which extend into spirals within the clay galleries. These spirals reorganize into spheres, when extracted from clay galleries.
A 1D chain-like Ag(I)-substituted Keggin polyoxotungstophosphate, K3[H3Ag(I)PW11O39]·12H2O, has been synthesized in a high yield and characterized by single-crystal X-ray diffraction, XRD, IR, TG/DTA and elemental analysis. When the polyoxotungstophosphate is dissolved in aqueous solutions, (31)P NMR, MS and conductiv…
The aim of this study is to develop degradable core-cross-linked polymeric micelles based on two water soluble methoxy-poly(ethylene glycol)-block-poly(aspartamide) (mPEG-PA) copolymers using the pH-sensitive imine bond. The ring opening polymerization of N-carboxyanhydride (NCA) was utilized to prepare the diblock co…
Treatment of [Mn(dpop)(H2O)2]Cl2 (dpop = 2,13-dimethyl-3,6,9,12,18-pentaazabicyclo-[12.3.1]octadeca-1(18),2,12,14,16-pentaene) with K4[Mo(CN)7]·2H2O under varied synthetic conditions afforded four different compounds: {[Mn(dpop)]4[(dpop)Mn(H2O)]2[Mo(III)(CN)7]3·27H2O}n (1), {[(dpop)Mn(H2O)][Mo(III)(CN)7][Mn(dpop)]3[Mo…
Monodispersed hollow magnetite nanospheres with diameter of about 462 nm and a shell thickness of approximately 90 nm were successfully synthesized through a simple solvothermal process in ethylene glycol (EG) in the presence of urea. The electron and transmission microscopy images showed that the obtained magnetite s…
Remarkably fast photoinduced charge separation in well-ordered self-assemblies of perylenediimide-graphene oxide (TAIPDI-GO) hybrid layers was observed in aqueous environments. Slow charge recombination indicates an effective charge migration between the self-assembled layers of PDI-GO hybrids following the charge sep…
Porous microspheres of iron oxide (Fe2O3) are synthesized using a double hydrophilic block copolymer of poly(ethylene oxide)-block-poly(acrylic acid) (PEO-b-PAA). The PAA block with negative charge strongly interacts with ferric ions. The assembly of primary nanoparticles at elevated temperature forms the porous micro…
In this paper, a facile, template-free, one-step solvothermal method to synthesize size- and shape-controllable α-GaOOH with hierarchical nanoarchitectures has been developed. Hyperbranched α-GaOOH nanocrystals with a sheaf-like morphology has been prepared via the alcoholysis process with GaCl3 and methanol as the re…
We report a facile graphene/graphite sheet assisted CVD process for the synthesis of high-areal-density HACNT arrays. Besides, some metal nanoparticles could eat the graphene/graphite sheets, forming serpentine holes on the sheets in the early stage, and finally leading to the precipitation of CNTs without an addition…
Bismuth nanocrystals were embedded in amorphous Bi 2 O 3 thin films grown under a nitrogen atmosphere at room temperature using pulsed laser deposition. As-grown Bi 2 O 3 -Bi thin films showed a high electrical conductivity of approximately 769 S/cm at 320 K, and the samples annealed in two steps at 200 and 300°C cons…
π-Conjugated alternating copolymers containing a tetramethylbithiophene unit show a strong tendency to form well-defined, sub- to several-micrometer-sized spheres.
We reported the synthesis of highly water-stable iron oxide nanoparticles by a simple one-pot reaction. Non-toxic polyethylene glycol MW 600 (PEG) acted as a solvent, capping agent and reducing agent in the synthesis of iron oxide nanoparticles. As a result of the synthesis, PEGylated small-size (4.2 ± 0.39 nm average…
Introducing multiple reactive functional groups at the periphery of dendrimer materials presents considerable challenges if the functionality is able to self-react. An efficient and facile approach to introducing masked thiols at the surface of polyester dendrimers is presented. One-pot, deprotection/thiol-acrylate Mi…
We provide a comprehensive picture of magnetotransport in graphene monolayers in the limit of nonquantizing magnetic fields. We discuss the effects of two-carrier transport, weak localization, weak antilocalization, and strong localization for graphene devices of various mobilities, through theory, experiments, and nu…
The biferrocene-based salt [Bifc]2[Ni(mnt)2]3 (Bifc = bis(isopropylthio)biferrocene; mnt = maleonitriledithiolate) contains a biferrocenium monocation and dication within the same crystal. The coexistence of Fe(3+) and mixed-valence Fe(2.5+), which resembles the valence state of magnetite, was confirmed by Mössbauer s…
The purpose of this study was to prepare composite microparticles of poly(3-hydroxybutyrate) (PHB) containing the drug ketoprofen (KET) coated with a layer of crosslinked chitosan (CHI) for application as a controlled drug-release system. Microparticles of PHB containing KET as a model drug were prepared using the emu…
