The atomic and magnetic structures of the La0.7Sr0.3CoO3 cobaltite are investigated using neutron diffraction at high pressures up to 4.2 GPa in the temperature range 16–300 K. The structural parameters are determined as functions of the pressure. It is revealed that the effect of high pressure leads to a decrease in…
Chlorophenoxyacetic acids are a well known family of herbicides. 4-Chlorophenoxyacetate (4-CPA), 2,4-dichlorophenoxyacetic (2,4-D), 2,4,5-trichlorophenoxyacetate, (2,4,5-T) have been intercalated into [LiAl2(OH)6]Cl·xH2O LDH ([Li–Al–Cl] LDH) by ion-exchange. The kinetics and mechanisms involved in the intercalation of…
The dielectric permittivity tensor components, εII and ε⊥, in the nematic phase of 6CB (4‐n‐hexyl‐4′‐cyanobiphenyl) were measured in the pressure range 0.1–130 MPa and the temperature range 12–58°C. The dielectric anisotropy, Δε(p, V, T) = εII ‐ ε⊥, was analysed in isothermal, isobaric and isochoric conditions taking…
In order to evaluate the efficacy of liposomes as a drug carrier for atherosclerotic therapy, a pharmacokinetic analysis of the uptake of liposomes by macrophages and foam cells in vitro and their distribution to atherosclerotic lesions in mice was carried out. In brief, liposomes of three particle sizes (500, 200 and…
Surface-enhanced resonance Raman scattering (SERRS) of Rhodamine 6G (R6G) adsorbed on colloidal silver clusters has been studied. Based on the great enhancement of the Raman signal and the quench of the fluorescence, the SERRS spectra of R6G were recorded for the samples of dye colloidal solution with different concen…
In the first part of this study, the inhibitor effect of single, binary and  ternary mixture of chromate, molybdate, nitrite, tetraborate, ortophosphate, benzoate, acetate, ascorbic acid on  the corrosion of carbon steel was investigated. Experiments were carried out in  neutral…
This issue of Journal of Materials Chemistry highlights recent progress in molecular magnetic materials. Eugenio Coronado and Dante Gatteschi introduce the issue and the importance of the field.
The development of new and innovative technologies and methods for treating environmental contaminants is a critical step in the effort to protect the environment and its components.The continuing investment of public and private resources in demonstration projects represents a major commitment to promoting the techni…
This paper is focused on the investigation of transformers internal electromagnetic forces caused by external fault. The simulations are based on the finite elements method (FEM) to model a three-phase transformer and also to calculate the forces via traditional mechanical and electrical equations. Normal operation an…
In this work, polyaniline (PANI) nanofibrous networks were prepared using ionic liquid (IL), 1-hexadecyl-3-methylimidazolium chloride (C16MIMCl), as a template through oxidative polymerization of aniline with ammonium persulfate. The resulting PANI was characterized by means of scanning electron microscopy (SEM), tran…
o achieve an attractive and consistent color appearance, cultured pearls are frequently treated by bleaching, dyeing (such as with silver nitrate), or exposure to radiation. A "new" color for cultured pearls was introduced to the market in 2000 (figure The induced brown color reportedly results from the bleaching of "…
The amount of PHB produced at pH 6.9 was 0.8, 0.5, 0.4, and 0.73 (g/mL -1 ) and 1.1, 0.65, 0.55 and 1.0 (g/mL -1 ), respectively in glucose, sago, thippi, molasses substrate based media. The present investigation revealed that bio effluents could be used for the production of PHB so as to decrease the pollution caused…
Acoustically monitored laser-induced optical breakdown (LIOB) has potential as an important tool to diagnose and treat living cells. Laser-induced intracellular microbubbles are readily detectable using high-frequency ultrasound, and LIOB can be controlled to operate within two distinct regimes. In the nondestructive…
Tetranuclear copper(II) complexes were obtained after simply dissolving [Cu(hfac)2] in formamide-methanol mixed solvents (Hhfac=1,1,1,5,5,5-hexafluoropentane-2,4-dione). X-Ray diffraction studies revealed that they possessed a tetranuclear double half-cubane core sandwiched with two trianionic ligands from 2,4,6-tris(…
Abstract Nanobiotechnology is the latest technology to provide disruptive—quantum leap—opportunities in drug development research. Examples of the utility of this approach are found increasingly in the scientific literature and the lay press. Whether for therapeutics, diagnostics, drug delivery, targeting, or some oth…
During the monitoring of the evolution of Au nanoparticles photo-synthesized via a conventional long-wave UV-visible irradiation (200 nm < λ < 600 nm) in an aqueous solution, two independent growth progresses of nanocrystals were observed. The first growth progress of nanoparticles was initiated between 90 and 96 h (D…
Isocyanide-bound model hemes always adopt the (dxz, dyz)4(dxy)1 ground state, however, we have found that the replacement of porphyrin by diazaporphyrin leads to the formation of an unprecedented low-spin bis(tert-butylisocyanide) complex with the (dxy)2(dxz, dyz)3 ground state.
Our understanding of diatom reproduction is limited, especially for marine planktonic centric diatoms. This project aimed to elucidate sexual behavior and gametogenesis in the mediophycean diatom, Thalassiosira angulata , and to determine the fine structure of its reproductive cells. A monoclonal culture of T. angulat…
Impedance matching refers to the suppression of reflected radiation from an interface and is a concept that applies right across the electromagnetic spectrum. In particular it has come to prominence in relation to the propagation of light in metallic structures and associated meta-materials. Whilst established for mic…
This paper describes the functionalization of oxidized boron-doped diamond (BDD) electrodes with N-(3-trimethoxysilylpropyl)pyrrole (TMPP) and the influence of this layer on the electrochemical transfer kinetics as well as on the possibility of forming strongly adhesive polypyrrole films on the BDD interface through e…
