The properties of the d-band structure of the transition metal atom in cubic LaBO(3) and SrBO(3) perovskites (where B = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) and their dependence on strain, d-band filling, and oxidation state were investigated using density functional theory calculations and atom-projected density of…
We report the synthesis and characterization of a series of boronsubphthalocyanine ( BsubPc ) dyes which have organic solubility >10 –2 M while being amenable to doping into polymeric films. To achieve high solubility we have placed the 3-pentadecylphenoxy molecular fragment in a variety of positions within the BsubPc…
Abstract Poly(aniline‐co‐ethyl 3‐aminobenzoate) (3EABPANI) copolymer was blended with poly(lactic acid) (PLA) and co‐electrospun into nanofibers to investigate its potential in biomedical applications. The relationship between electrospinning parameters and fiber diameter has been investigated. The mechanical and elec…
Cyano-bridged transition metal compounds, represented as Na x Mn[Fe(CN) 6 ] y · z H 2 O, are promising cathode materials for Li ion secondary batteries. Here, we systematically investigated their structure against temperature ( T ) and cation concentration ( x ). We observed successive changes in their structure from…
Two groups of polymer nanocomposite samples were synthesized. One of them was Poly(vinyl chloride) (PVC) loaded with different concentrations of carbon nanopowder (CNP), while the other was PVC loaded with different concentrations of carbon nanotubes (CNTs). The dependence of the tensile mechanical parameters, rheolog…
Hydrothermal method, which provides an effective approach to produce pure‐phase BiFeO 3 ‐based solid solution was used to synthesize BiFeO 3 –BaTiO 3 powders. The phase evolution was found to be connected with reaction temperature, initial KOH concentration, and duration time. The results show that perovskite cubic 0.…
Silver nanoparticles (AgNP) confined within porous starch have been prepared in a simple, green and efficient manner, utilising the nanoporous structure of predominantly mesoporous starch (MS) to act as nanoparticle stabiliser, support and reducing surface. MS/AgNP materials present high surface areas (S(BET) > 150 m(…
Abstract The well‐defined azoindazole‐containing homopolymer, poly(6‐{6‐[(4‐dimethylamino) phenylazo]‐indazole}‐hexyl methacrylate) (PDHMA), and amphiphilic diblock copolymer, poly({6‐[6‐(4‐dimethylamino)phenylazo]‐indazole}‐hexyl methacrylate)‐ b ‐poly(2‐(dimethylamino)ethylmethacrylate) (PDHMA m ‐ b ‐PDMAEMA n ), we…
This study investigates the effects of fiber type, fiber loading, and coupling agent on the performance of oil palm biomass (OPB) fiber composites. Fiber composition and fiber morphology were evaluated by scanning electron microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDAX). Grinded fiber was compounded i…
In this study, fibrin, which is superior to fibrinogen in both structural and functional properties, has for the first time been electrospun successfully into uniform nano fibers resembling the extracellular matrix (ECM). The methods of fabrication and characterization of this unique scaffold are presented. Using poly…
Schlafende Riesen: Ein hoch effizienter, lichtresponsiver, reversibler und stabiler Aggregationsprozess wurde entwickelt, der die Zellagglomeration in der Gewebebildung nachahmt. Als Bausteine wurden hyperverzweigte Riesenpolymervesikel (5–10 μm) verwendet (siehe Schema), und die Vesikelaggregate können durch abwechse…
Castration-resistant prostate cancer remains incurable and a major cause of mortality worldwide. The absence of effective therapeutic approaches for advanced prostate cancer has led to an intensive search for novel treatments. Emerging nanomedical approaches have shown promising results, in vitro and in vivo, in impro…
The incorporation of dendrimer into three lyotropic liquid crystalline (LLCs) mesophases is demonstrated for the first time. A second generation (G2) of poly(propylene imine) dendrimer (PPI) was solubilized into lamellar, diamond reverse cubic, and reverse hexagonal LLCs composed of glycerol monooleate (GMO), and wate…
The microstructure and electrical properties of Er 2 O 3 ‐doped ZnO – V 2 O 5 – MnO 2 – Nb 2 O 5 varistor ceramics were investigated with different contents of Er 2 O 3 . Increasing content of Er 2 O 3 increased the sintered density (5.51–5.61 g/cm 3 for Er 2 O 3 ‐doped samples) and reduced the average grain size (5.2…
Large aspect ratio 3D microstructures (arrays of square posts and linear rectangular gratings) fabricated in a number of azobenzene-containing materials by soft lithography were manipulated by a single beam of polarized light. The materials exhibited different response to the beam orientation and the direction of ligh…
In this work, osmotic second virial coefficients (B(22)) were determined and correlated with the measured solubilities for the proteins, α-amylase, ovalbumin, and lysozyme. The B(22) values and solubilities were determined in similar solution conditions using two salts, sodium chloride and ammonium sulfate in an acidi…
The effect of the partial substitution of Mn by Cr on the structural and magnetic properties of Ni–Mn–In metamagnetic shape memory alloys is investigated. It is found that a Cr-rich second phase appears for quite low Cr concentrations, pointing out a very low solubility of Cr in Ni–Mn–In. Nevertheless, the martensitic…
A convenient one‐step solvothermal route has been developed to synthesize monodispersed barium titanate with narrow size distributions. The key point of this method is the controlling of hydrolysis of Ti(OC 4 H 9 ) 4 with Diethylene glycol. The as‐prepared BaTiO 3 nanoparticles were characterized by X‐ray diffraction,…
Hoch besetzt: Eine hoch poröse Form von Mg(BH4)2 (siehe Bild; Mg grün, BH4 blau, Elementarzellen rot) adsorbiert H2, N2 und CH2Cl2 reversibel. Bei hohen Drücken wandelt sich das Material in ein verschachteltes Gerüst um, das eine um 79 % höhere Dichte als die anderen Polymorphe aufweist. Mg(BH4)2 kann als ein Koordina…
Die Morphologie von Gold-Nanopartikeln (GNPs) auf CeO2-Trägern und unter verschiedenen CO- und O2-Partialdrücken wird beschrieben; ihre Morphologie korreliert gut mit ihrer katalytischen Aktivität. Adsorbierte CO-Moleküle stabilisieren die {111}- und {100}-Flächen von GNP-Polyedern; O2-Moleküle dissoziieren an den GNP…
