Abstract Two MnII coordination polymers based on the flexible bis(benzimidazole) and dicarboxylic acids, namely, [Mn(L1)(bpdc)(H2O)0.5]n (1) and [Mn(L2)(Htbi)2]n (2) [L1 = 1,4‐bis(5,6‐dimethylbenzimidazol‐1‐ylmethyl)benzene, H2bpdc = 4,4′‐biphenyldicarboxylic acid, L2 = 1,4‐bis(5,6‐dimethylbenzimidazole)butane, H2tbi…
Abstract The sulfide La4Cd4In2S13 in the quaternary RE/M/N/Q (RE = rare‐earth metal; M = Zn, Cd; N = Ga, In; Q = chalcogenides) system was prepared from stoichiometric mixtures of the elements by solid‐state reactions at 1223 K in an evacuated silica tube. The La4Cd4In2S13, crystallizing in the Pbam space group, is is…
We investigate the effect of topology on the equilibrium behavior of singly tethered ring polymers adsorbed on an attractive surface. We focus on the change of square radius of gyration Rg(2), the perpendicular component Rg⊥(2) and the parallel component Rg‖(2) to the adsorbing surface, the mean contacting number of m…
The study aims to determine the influence of coating and composition of raw materials to physical and mechanical properties of composite board from singkong trunk and plastic waste and to know the best treatment . C omposite board size was 30 cm x 30 cm x 1 cm. The plastic waste function as an adhesive and mix in thre…
Two structurally different copper(II) complexes of the compositions [{Cu(9dhx)(H2O)3}2(µ-SO4)2] (1) and [Cu(9dhx)2(H2O)2(NO3)2]·H2O (2), involving 9-deazahypoxanthine (9dhx; 6-oxo-9-deazapurine; 9-deazahypoxanthine), have been prepared and characterized by elemental analysis, infrared and electronic spectroscopy, elec…
In this paper, a simple, one-step chemical synthesis of Au@poly(m-phenylenediamine) (PMPD) core-shell nanoparticles by direct dropping aqueous chloroauric acid aqueous solution to m-phenylenediamine aqueous solution was reported, which is a facile and green method. We further evaluate the use of the obtained Au@PMPD t…
The ab-initio molecular dynamics simulations were conducted to etude the microscopic atomic and electronic structures of Co 54 Ta 11 B 35 bulk metallic glasses in the surface composition. The structure properties such as partial pair correlation function, bond pairs and Voronoi tessellation analysis were analyzed. The…
The reaction of Eu2O3 with fuming nitric acid, trifluormethanesulfonic acid, and its anhydride in torch-sealed glass ampoules at 120 °C gave the europium compound (NO)5[Eu(O3SCF3)8] (orthorhombic, Fddd, Z = 16, a = 1932.69(4), b = 2878.44(7), c = 2955.12(7) pm, V = 16439.7(7) Å(3)). The compound exhibits the [Eu(O3SCF…
Abstract Wir berichten über die Synthesen, Kristallstrukturen und physikalischen Eigenschaften von [HFe19O14(OEt)30] und [{Fe11(OEt)24}∞]. Das oktaederförmige Molekül [HFe19O14(OEt)30] kann als dreidimensionaler Ausschnitt aus dem Natriumchloridgitter aufgefasst werden, wobei das zentrale Eisenion von sechs μ6‐Oxo‐Gru…
Phospholipids, dendrimers, and polymers are each able to assemble to form vesicles, but each has limitations such as leakiness and multistep syntheses. A new class of versatile amphiphilic block copolymers is reported containing hyperbranched polyglycerol (HPG) and polystyrene (PS) units. These compounds self-assemble…
This paper presents a methodology to directly investigate on the nanometer scale electrical properties of the nucleation layer of grown diamond films, which are important when the film is used as an electrode with the current flow across the nucleation layer. The diamond films are grown on Si substrates. In this metho…
The authors demonstrate a high performance electrically controlled birefringence (ECB) mode with solution-derived La2O3 films at various molar concentrations. Uniform and homogeneous liquid crystal (LC) alignment was spontaneously achieved on the La2O3 films for lanthanum concentrations at ratios greater than and equa…
Abstract Ternary liquid-liquid equilibria for four systems containing ionic liquids {1-ethyl-3-methylimidazolium ethylsulphate ([EMIM][EtSO 4 ]) and 1-ethyl-3-methylpyridinium ethylsulphate ([EMPY][EtSO 4 ])} (1)+pyrrole/pyridine(2)+isododecane (3) have been determined at 298.15 K. The solute distribution coefficient…
The Fe(III) ions in the hybrid title salt, (C7H11N2)[Fe(C2O4)2(H2O)2]·0.5H2O, show a distorted octa-hedral coordination environment, with four O atoms from two chelating oxalate dianions and two O atoms from two cis aqua ligands. The average Fe-O(oxalate) bond length [2.00 (2) Å] is shorter than the average Fe-O(water…
The paper focuses on the analysis of the multicaloric effect in solids. In particular, the presented approach is applicable to thin films as well. For the piezoelectric material, the multicaloric phenomenon includes two well-known effects: electro and elastocaloric; and two new ones - piezoelectocaloric and flexocalor…
Abstract Mesoporous C and N codoped anatase nanocrystal–carbon composites have been synthesized by chelation‐assisted coassembly of urea, TiCl4, resols, and triblock copolymer. The composite catalysts have biphasic constituents in the pore walls of amorphous carbon and C,N‐codoped anatase nanoparticles (≈4.0 nm) that…
Diamond lateral p–n junctions were fabricated on (111) substrates by selective growth of n‐type diamond around a p‐type layer. We investigated the effects of both the step‐flow growth direction of n‐type diamond and the crystal face of the p‐type sidewalls on the structure and electrical properties of the lateral p–n…
Titanium (Ti)-wear particles, formed at the bone-implant interface, are responsible for aseptic loosening, which is a main cause of total joint replacement failure. There have been many studies on Ti particle-induced function changes in mono-cultured osteoblasts and synovial cells. However, little is known on extracel…
A novel series of imidazolium quaternized polymers based on poly(chloromethyl styrene) has been designed and synthesized, using nitroxide mediated polymerization and post-polymerization functionalization. They are characterized by ATR-FTIR (attenuated total reflectance-Fourier transform infrared spectra) and 1H NMR in…
Colloidal CdSe quantum dot (QD) core ensembles were photodimmed and allowed to recover in the dark using ambient thermal energy at a range of temperatures. Nonlinear thermal recovery is well described by a stretched exponential function, and further analysis yields an underlying probability distribution of rate consta…
