XRD patterns confirmed that the increase in interlayer spacing of

XRD patterns confirmed that the increase in interlayer spacing of Na-montmorillonite (Na-MMT) from 1.21 to 1.64 nm supports the intercalation. Although the width of the intercalated, delaminated montmorillonite aggregates are less than 100 nm (as seen in transmission electron microscopy), the prepared samples

are members of the intercalated composite group. The samples exhibited better thermal stability than the pure polymer. Nitrogen adsorption capacity decreased due to the hindering of molecule diffusion and shielding of the intercalated https://www.selleckchem.com/ALK.html aggregates by the polymer matrix. The decrease in moisture and water uptake of the samples indicated that the hydrophilic nature of montmorillonite changed greatly due to

the hydrophobicity with increasing polymer content. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 123: 3662-3667, 2012″
“Nonlinear optical properties of luminescent multinuclear platinum(II) complex of branched alkynyls in benzene solution are investigated at room temperature by using two-photon fluorescence (TPF) technique. It is found that the material shows unusual nonlinear optical characteristics under the excitation of near infrared femtosecond laser pulses. selleck compound The self-focusing of laser beam energy during propagation of the laser pulses in the sample with large nonlinear coefficient for the refractive index is observed. Based on this phenomenon, a new method for measuring the nonlinear coefficient and two-photon absorption cross section of materials is proposed. (C) 2011 American Institute of Physics.

“Curculigo orchioides rhizome extracts were evaluated for antibacterial activity against pathogenic strains of Gram-positive (Staphylococcus aureus and Staphylococcus epidermidis) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa and Salmonella typhimurium) bacteria. Because the steam distilled selleck kinase inhibitor preparation was found to be the most active amongst the different extracts, its antibacterial activity

against the aforementioned strains was compared to the standard antibiotics gentamycin, ampicillin, doxycycline and erythromycin. Only the clinical isolate of S. aureus showed more sensitivity towards water extracts than the standard strain. Also, the steam distilled fraction was more effective against Gram-positive strains than Gram-negative strains. Therefore, the steam distilled extract from C. orchioides has a potential application as an antiseptic for the prevention and treatment of antibacterial infections, and the present findings support its traditional local uses.”
“Transient suppression of the motor cortex and of the speech areas cause well-described postictal phenomena following seizures involving the respective cortical areas. Pain is a rare symptom in epileptic seizures. We present a patient with painful tonic seizures in the left leg.
