High-quality nanocrystalline BiGaO3 (BGO) films have been prepared by a modified sol-gel method. X-ray diffraction analysis shows that the films are polycrystalline and exhibit an orthorhombic structure. The dispersion functions near infrared-ultraviolet region were extracted by fitting spectroscopic ellipsometry with…
Blends of bloodmeal-based thermoplastic (NTP) and polybutylene succinate (PBS) were prepared to study the effect of compatibilization on mechanical properties. The Taguchi method was used for experimental design and the results were analysed in terms of signal-to-noise (S/N) ratios using analysis of variance (ANOVA).…
A graphene bilayer is known to perfectly reflect normally incident electrons due to their chirality. This is similar to Klein tunneling, which, in a monolayer, is instead responsible for perfect transmission at normal incidence. Stacking defaults turn each parabolic band crossing of a bilayer into pairs of Dirac cones…
We use static as well as time-dependent first-principles computations to study interaction of the CO, NO, and HCN molecules with the Ag8 nanocluster. The many-body based GW correction is applied for accurate description of the highest occupied (HOMO) and the lowest unoccupied (LUMO) molecular orbital levels. It is arg…
Aryl substituted β-alkenol 1-(dimethyl-1,3-thiazol-2-yl)-3,3,3-trifluoropropenol (DMTTFP) was employed as an efficient metal chelator to obtain volatile monomeric precursors containing Fe II and Fe III centers. [Fe(DMTTFP) 2 ] ( 1 ) and [Fe(DMTTFP) 2 (OBu t )] ( 2 ) were synthesized by reacting suitable starting mater…
Synthesis and structural properties of nickel oxide-gadolinium doped ceria (GDC) nanocomposite via sol–gel/electrospinning route were investigated for the first time, and the results were compared with those obtained through gel combustion method. Various analytical techniques, such as XRD, SEM, EDS, TEM and BET, were…
We investigate the temperature induced ferromagnetic to paramagnetic phase transition in Co substituted La(FexCoySi1−x−y)13 with x = 0.9 and low Co content of y = 0.015 (Tc≃200 K) by means of magneto-optical imaging with indicator film and by calorimetry at very low temperature rates. We were able to visualize the mot…
Au@SiO 2 core–shell nanowires have been successfully fabricated by irradiating infrared nanosecond pulses to linearly self-assembled and silica-coated gold nanorods. Gold nanorods have been self-assembled linearly by adding isopropanol in the absence of any assembling agents to form gold nanochains. The end-to-end ass…
Nanoparticles are potential threats to human health and the environment; however, their medical applications as drug carriers targeting cancer cells bring hope to contemporary cancer therapy. As a model drug carrier, gold nanoparticles (GNPs) have been investigated extensively for in vivo toxicity. The effect of GNPs…
Ordered ultrathin titanium oxide films have been produced under ultrahigh vacuum (UHV) conditions by oxidation of a Pt 3 Ti(111) single crystal at elevated temperatures. Depending on substrate temperature, oxygen dosage, and partial pressure, four different titania phases have been observed. All phases have been inves…
High Resolution Image Download MS PowerPoint Slide Dipositive cation substitution in sulfate minerals has been a topic of investigation both experimentally and computationally. Here the possibility of tripositive cation substitution with accompanying vacancy formation is considered, specifically lanthanum ion substitu…
In this study, a magneto-mechano-electric (MME) composite cantilever made of a piezoelectric bimorph and magnets for low-frequency magnetoelectric (ME) coupling was analyzed theoretically and its MME coupling equivalent circuit was developed. Based on equivalent circuit analyses, the dependences of the ME performances…
The pyrazole-based tridentate diol ligand 2-(1-(2-hydroxyethyl)-1H-pyrazol-3-yl)phenol (H2L) forms a cubane-type complex [Co4L4(MeOH)4] (1) that features a {Co4O4} core and four exogenous MeOH ligands. Electrospray ionization mass spectrometry suggests that the MeOH ligands are easily lost, and thermogravimetric analy…
A brief history is given of how X-ray diffraction data from crystals have been recorded. Today there are new possibilities, spawned by the availability of free electron lasers that produce powerful femtosecond long X-ray pulses.
Highly ordered mesoporous TiO 2 modified by CdS, CdSe, and ZnS quantum dots (QDs) was fabricated by successive ionic layer adsorption and reaction (SILAR) method. The quantity of material deposition seems to be affected not only by the employed deposition method but also and mainly by the nature of the underlying laye…
Nanometer‐scale optical waveguides are attractive due to their potential applicability in photonic integration, optoelectronic communication, and optical sensors. Nanoscale white light‐emitting and/or polychromatic optical waveguides are desired for miniature white‐light generators in microphotonic circuits. Here, pol…
In this paper, we describe stimuli-responsive hydrogels prepared from a rigid rod-like polyelectrolyte 'imogolite' and a dicarboxylic acid. The hydrogel exhibited thixotropy in response to mechanical shock within the order of seconds or sub-seconds. Here, using the latest structural/rheological characterisation techni…
Abstract A series of organic dyes were synthesized that contain an o ‐carborane unit in combination with phenanthrene, tolane, and BODIPY moieties. In solution, compound 7 a , which has phenanthrene and tolane units, does not emit as a result of an intramolecular charge transfer (ICT) from the emitters to the C1C2 bo…
In the international community, human dependence on plastic is increasing. Meanwhile, global petroleum reserves are diminishing. The cost of this demand on petroleum use is not only economic; there are also escalating human and animal health concerns, environmental implications, and the inherent obligation to prepare…
Abstract This study reports on the thermo-mechanical synthesis of carbon nano onions from elemental graphite powders. Initially, amorphous carbon was obtained by high energy ball milling technique from graphite powders. X-ray spectra taken from ball milled samples indicated that the hexagonal graphite, composed of lay…
