Pyrazine- N,N ′-dioxide (pzdo) was used as a linker in the design and synthesis of hybrid octacyanometalate-based networks. Four new compounds Na 6 [W V (CN) 8 ] 2 (pzdo) 7 ·5H 2 O ( 1 ), K 3 [W V (CN) 8 ](pzdo) 2 ·4H 2 O ( 2 ), {Mn II 6 (pzdo) 4 (MeOH) 10 [W V (CN) 8 ] 4 }·4MeOH ( 3 ), and {Mn II 2 (pzdo)(H 2 O) 4 [W…
Novel platinum(IV)–texaphyrin conjugates were designed and synthesized in order to target cancer cells preferentially and to deliver platinum. Protected from light, these compounds are inert in aqueous environments and do not interact with DNA. However, following exposure to ambient light, a reduced, active PtII speci…
The water insoluble complex Rb4[Ru(II)(bpy)3]5[{Ru(III)4O4(OH)2(H2O)4}(γ-SiW10O36)2], ([Ru(II)bpy]5[Ru(III)4POM]), was synthesized from Rb8K2[{Ru(IV)4O4(OH)2(H2O)4}(γ-SiW10O36)2] and used for electrocatalytic water oxidation under both thin- and thick-film electrode conditions. Results demonstrate that the [Ru(II)bpy]…
Human umbilical cord blood-derived mesenchymal stem cells (hUC-MSCs) have been widely used in tissue engineering. The aim of this study is to evaluate the ability of poly (3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) scaffolds coated with polyhydroxyalkanoate binding protein fused with arginyl-glycyl-aspartic aci…
The electromechanical response of a 3 nm thick amorphous LaAlO3 layer obtained by molecular beam epitaxy has been studied using scanning probe microscopies. Although this kind of sample is not ferroelectric due to its amorphous nature, the resulting images are identical to what is generally obtained on truly ferroelec…
ZnO thin films fabricated by a low-temperature sol–gel conversion method (L-ZnO) were employed as n-type electron-transporting layers (ETLs) in depleted-heterojunction quantum dot solar cells (DH-QDSCs). Thin films of PbS (∼200 nm) fabricated by spin-coating a colloidal PbS QD solution layer by layer were used as the…
The reactions of trivalent lanthanides and actinides with molten boric acid in high chloride concentrations result in the formation of M4[B16O26(OH)4(H2O)3Cl4] (M = Sm, Eu, Gd, Pu, Am, Cm, Cf). This cubic structure type is remarkably complex and displays both chirality and polarity. The polymeric borate network forms…
Two new hexanuclear symmetric dysprosium wheels, namely, [Dy6(L1)6(L')6(OCH3)6(2CH3OH)] and [Dy6(L2)6(L')6(OCH3)6(2CH3OH)] (L1H = pivalic acid and L2H = 3,5-dinitrobenzoic acid, L'H= 2,6-dimethoxyphenol) were isolated employing a mixed-ligand strategy. The strategic introduction of two different auxiliary groups with…
Polyoxometalates are robust and versatile multidentate oxygen-donor ligands, eminently suitable for coordination to trivalent lanthanoid ions. To date, 10 very different structural families of such complexes have been found to exhibit slow magnetic relaxation due to single-molecule magnet (SMM) behaviour associated wi…
We report the enhancement of hole injection and electroluminescence (EL) in an organic light emitting diode (OLED) with an ordered Ag nanodot array on indium-tin-oxide (ITO) anode. Until now, most researches have focused on the improved performance of OLEDs by plasmonic effects of metal nanoparticles due to the diffic…
Abstract Iso‐selective initiators for the ring‐opening polymerization (ROP) of rac‐lactide are rare outside of Group 13. We describe the first examples of highly iso‐selective lutetium initiators. The phosphasalen lutetium ethoxide complex shows excellent iso‐selectivity, with a Pi value of 0.81–0.84 at 298 K, excelle…
Double-decker complexes based on single-molecule magnets (SMMs) are a class of highly promising molecules for applications in molecular spintronics, wherein control of both the ligand oxidative states and the 2D supramolecular structure on carbon materials is of great importance. This study focuses on the synthesis an…
In this paper, the nonlocal Reddy beam model is employed to study the vibration characteristics of armchair and zigzag single-walled carbon nanotubes (SWCNTs) subjected to a uniform temperature rise. The equivalent Young's modulus and shear modulus for armchair and zigzag SWCNT are derived using an energy-equivalent m…
Although solvent is the major component of the gel, it still remains unclear how the solvent molecules take part in the formation of the gel nanostructures in many gels. In this study it was observed that the vicinal effect on gel formation as well as their nanostructures, that is, the vicinal solvent molecules to the…
A comparison of static and dynamic cushioning properties of polyethylene foam is discussed in this paper. A dynamic factor function is defined and obtained from the analysis on the experimental data from compression and cushion tests. The deformation energy per unit volume is taken into consideration to make an estima…
The design and fabrication of oxygen barrier films is important for both fundamental and industrial applications. We prepared three different thin films composed of graphene oxide (GO) and laponite (LN), a typical low cost inorganic clay, with the GO/LN volume ratios of 1.9/0.1, 1.7/0.3 and 1.5/0.5 together with a dou…
1,3,5,7,9,11,13-heptaphenyl-15-vinyl cage half siloxane (Phenyl-Vinyl-POSS) was synthesized via the corner capping reaction of incompletely condensed silsesquioxane, [(C6H5)7Si7O9(OH)3], with trichlorovinylsilane. The chemical structure of Phenyl-Vinyl-POSS was characterized by FT-IR, 1H-NMR, mass spectrometry and ele…
The performance of a simple multiscale approach to rapidly screen the second‐order nonlinear optical (NLO) susceptibilities [χ(2)] as well as the refractive indices of organic crystals solely from the knowledge of their crystal structure is demonstrated. The method combines first principles calculations of the molecul…
Structural phase separation in AxFe2-ySe2 system has been studied by different experimental techniques, however, it should be important to know how the electronic uniformity is influenced, on which length scale the electronic phases coexist, and what is their spatial distribution. Here, we have used novel scanning pho…
Optical polarimetry measurements of the orientational order of a discotic liquid crystal based on a pyrene derivative confined in parallelly aligned nanochannels of monolithic, mesoporous alumina, silica, and silicon as a function of temperature, channel radius (3-22 nm) and surface chemistry reveal a competition of r…
