A number of fluorescent benzothiadiazole dyes have been synthesised and their optical properties, when dispersed in a liquid crystal host phase, examined. These dyes have five linearly π-conjugated aromatic ring systems (both with and without ethene and 1,3-butadiene spacers). The liquid crystalline host medium, used…

A series of donor-acceptor substituted stilbene and diphenylacetylene derivatives and their octupolar analogues have been synthesized and the linear and nonlinear optical properties (beta) studied by both experiments and theoretical calculation. The lambda(max) of the dipoles increases with the conjugation length and…

Texture engineering using reactive-templated grain growth (RTGG) is reviewed as a key processing technique for lead free piezoelectric ceramics. Bismuth layer structured ferroelectric ABi4Ti4O15 (A=Na0·5Bi0·5, Ca, Sr) ceramics with a highly preferred {001} orientation were fabricated with enhanced piezoelectric proper…

We theoretically propose that the optical analog of a Lorentz force acting on a ray of light is realized in multiferroic materials such as ${\mathrm{GaFeO}}_{3}$ showing the magnetoelectric effect. The toroidal moment $\stackrel{\ensuremath{\rightarrow}}{T}=\ensuremath{\sum}_{j}{\stackrel{\ensuremath{\rightarrow}}{r}}…

Abstract Poly(lactide) (PLA) polymers have garnered increased attention in the last few years as food packaging materials because they are environmentally friendly polymers. As the production of PLA increases and price per pound drops, PLA is becoming a growing alternative as a green food packaging material. In this r…

In this study, selective cancer cell targeting of biodegradable poly(lactic acid) (PLA) nanoparticles (NPs) has been investigated in vitro. SKOV-3 (HER2 positive) ovarian cancer and Daudi (CD20 positive) lymphoma cell targeting was mediated by anti-HER2 (trastuzumab, Herceptin) and anti-CD20 (rituximab, Mabthera) mono…

We have synthesized the solid solution, Sr_2Fe_1+xMo_1-xO_6 with -1 <= x <= 0.25, the composition x = 0 corresponding to the well-known double perovskite system Sr2FeMoO6. We report structural and magnetic properties of the above system, exhibiting systematic variations across the series. These results restrict the ra…

Remarkable selectivity (88 % in the steady-state reaction and 94 % in the pulse reaction) is observed in the direct synthesis of phenol from benzene with molecular oxygen over a Re/zeolite catalyst prepared by chemical-vapor deposition. The novel interstitial-N/Re clusters are formed with NH3 and are essential for the…

BACKGROUND: Although there is a well-documented risk of acute renal failure (ARF) with the iodinated contrast agents, intravenous gadolinium-based contrast agents are considered non-nephrotoxic and have been widely used for magnetic resonance imaging (MRI). However, debate continues regarding the safety issue of gadol…

The ion-bombardment induced evolution of intermixing is studied by molecular dynamics simulations and by Auger electron spectroscopy depth profiling analysis (AESD) in Cu/Co multilayer. It has been shown that from AESD we can derive the low-energy mixing rate and which can be compared with the simulated values obtaine…

The phenomena of exchange anisotropy is well known in terms of static magnetization properties such as enhanced coercivity and magnetization loop shifts. These effects are primarily associated with effective anisotropies introduced into the ferromagnet by exchange coupling with a strongly anisotropic antiferromagnet.…

Good cholesterol: Oligo(p-phenylenevinylene)s (OPVs) that are mono- or disubstituted with cholesterol moieties form pseudo-J and pseudo-H aggregates, respectively (see picture), which lead to coiled and twisted helical structures with distinct optical, chiroptical, and morphological properties.

One of the most spectacular phenomena in physics in terms of dynamical range is the glass transition and the associated slowing down of flow and relaxation with decreasing temperature. That it occurs in many different liquids seems to call for a ‘universal’ theory. In this article, we review one such theoretical appro…

The thermal quenching of Eu 2+ 5d–4f emission on Ba, Sr, or Ca sites in compounds is often attributed to a large displacement between the ground state and excited state in the configuration coordinate diagram. This work will demonstrate that the ionization of the 5d electron to conduction band states is the genuine qu…

OBJECTIVE: This study evaluates a novel photon radiation detector system for in vitro biokinetic measurements. METHODS: A cell-culture well can be considered to consist of two different compartments: the cells and the medium. By placing the well on a lead-collimated scintillation (NaI(T1)) detector, changes in activit…
