In situ sol-gel polymerization is demonstrated for fabricating transparent poly(methyl methacrylate) (PMMA)-ZnO quantum dot (QD)- hybrid materials in bulk dimension. The transparent PMMA-ZnO QD hybrid materials exhibit enhanced UV-shielding effects in the entire UV range, even at concentrations as low as 0.02 wt %.
Abstract Acene werden wegen ihrer einzigartigen elektronischen Eigenschaften, die auf der Topologie ihrer π‐Systeme beruhen, seit langem untersucht. Berichte über die bemerkenswerten Halbleitereigenschaften höherer Homologe haben in letzter Zeit zu verstärkten Forschungsaktivitäten geführt. Es wurden neue Verfahren zu…
The structure of the smut film and underlying surface morphology of aluminum AA1050 electrograined in hydrochloric acid with additions of acetic acid, citric acid, or disodium phenyl phosphate dihydrate was studied. In addition, a series of titration experiments was undertaken to determine changes to the buffering eff…
Abstract Poly(dimethyl trimethylene carbonate) (PDTC) and poly(trimethylene carbonate) (PTMC) were synthesized by ring‐opening polymerization (ROP) of dimethly trimethylene carbonate (DTC) and trimethylene carbonate (TMC) in the presence of five kinds of natural amino acids ( L ‐alanine, L ‐valine, L ‐leucine, L ‐prol…
Abstract Star‐shaped, star‐ block ‐linear, and hyperbranched poly(1,3‐cyclohexadiene) (PCHD) (co)polymers were synthesized through a convergent living anionic polymerization process or via addition of divinylbenzene. Chemical modification of star‐shaped PCHDs, including aromatization, hydrogenation, fluorination, and…
This paper presents a study on electrochemical lithiation of CoMnSb with a half-Heusler structure as anode material for Li-ion batteries. During the first electrochemical lithiation, the CoMnSb electrode showed , which corresponds to a large volumetric capacity of . Combined first principles and X-ray diffraction stud…
Abstract Luminescent mononuclear bipyridine platinum(II) complexes bearing linear alkyl chains, [Pt(CN)2(dCnbpy)] (n=9 and 11) have been prepared and characterized. These complexes are soluble in various organic solvents and exhibit remarkable solvent dependence and concentration dependence of the luminescence at room…
The dumbbell-shaped aromatic amphiphilic molecules consisting of hexa- p -phenylene-conjugated carbazole moieties on both ends as a rigid rod segment and oligoether chains with different cross-sections (i.e., linear branch ( 1 ), dibranch ( 2 ), and tetrabranch ( 3 )) attached to a carbazole as flexible chains were sy…
The electrical properties of Nb-doped ceramics with and without excess were investigated for anodes and interconnects of SOFCs by a dc four-probe conductivity measurement. The microstructures and the grain boundary properties were revealed by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy, SE…
A protocol for ultrathin nanoprecise coating of individual multiwall carbon nanotubes with amorphous europium hydroxide was developed. The nanocoated carbon nanotubes were successfully prepared by in situ deposition of europium hydroxide in the aqueous suspension by means of dative bonds to oxygen containing groups on…
Abstract A series of copolymers have been synthesized by the ring‐opening polymerization of glycolide, L ‐lactide, and ϵ‐caprolactone with zirconium(IV) acetylacetonate [Zr(Acac) 4 ] or stannous octoate [Sn(Oct) 2 ] as the catalyst. The resulting terpolymers have been characterized by analytical techniques such as pro…
Effective targeting of drugs to cells requires that the drug reach the target cell and interact specifically with it. In this study, we synthesized a biomacromolecular, multivalent construct intended to target glioblastoma tumors. The construct was created by linking three dodecapeptides, reported to bind the alpha 6b…
Quantum dot (QD) solubilization, conjugation with biomolecules, column purification, and labeling of human HepG2 cells with transferrin-QD (Tf-QD) conjugates are reported in detail in this article. Water-soluble QDs (WQDs) were obtained using sodium thiolycolate to replace the surface ligand tri-n-octylphosphine oxide…
The authors describe how a commercially available test set has been used to make preliminary determinations of condition of medium voltage underground power cables with extended cross-linked polyethylene cable insulation at remote sites in north-east Queensland. Polarisation and depolarisation currents are measured wi…
Abstract Novel 2‐aminopyrimidines substituted with two electron‐donor dialkylamino groups and either one dicyanovinyl ( 4a – d ) or one tricyanovinyl ( 7a – d ) electron‐acceptor group have been synthesized, and the balance between their push–pull character and their aromatic behaviour has been studied by experimental…
Abstract It is well known that gadolinium doped ceria (10 GDC) undergoes significant compositional expansion when exposed to low oxygen partial pressures. When constrained, such expansion results in mechanical stresses in the ionic solid. Although significant work has been done in evaluating the magnitudes of this exp…
Abstract A new copper(I) carboxylate complex with 3,5‐bis(trifluoromethyl)benzoate ligands, [Cu(O 2 C(3,5‐CF 3 ) 2 C 6 H 3 )] ( 1 ), has been prepared in high yield and fully characterized. An X‐ray diffraction study revealed a remarkable infinite double‐helical chain motif held together by cuprophilic interactions ra…
It is known that within the interacting electron model Hamiltonian for the one-dimensional $\frac{1}{4}$-filled band, the singlet ground state is a Wigner crystal only if the nearest-neighbor electron-electron repulsion is larger than a critical value. We show that this critical nearest-neighbor Coulomb interaction is…
Within a general theoretical framework, we study the effective, deformation-induced interaction between two colloidal particles trapped at a fluid interface in the regime of small deformations. In many studies, this interaction has been computed with the ansatz that the actual interface configuration for the pair is g…
Effects of electric field-frequency, electric field-amplitude, mechanical stress, and temperature on the hysteresis area, especially the scaling form, were investigated in soft lead zirconate titanate (PZT) bulk ceramics. The hysteresis area was found to depend on the frequency and field-amplitude with the same set of…
