The structure, morphology, mechanical

The structure, morphology, mechanical NVP-LDE225 manufacturer properties, and thermal stability of these hybrid materials were investigated by FTIR, SEM, tensile shear test (TSS), and TG. FTIR spectra indicated that the multiple reactive functional silanol group Si-OH on the surface of SiO(2) particles reacted with PVA and PF. Compared with pure PF, the composite 50-50-3% exhibited the maximum shear strength which increased by 158%, whereas the elongation at break increased by 63%. Morphological results agreed well with the mechanical properties. The TG results suggested that the composite material 50-50-3% and pure PF had almost the same thermal stability because silica sol and PVA had opposite effects

on the heat resistance of the hybrid materials. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 744-751, 2011″
“Microscopic two-level systems (TLSs) are known to contribute to loss in resonant superconducting microwave circuits. This loss increases at low power and temperatures as the TLSs become unsaturated. We find that the loss is dependent on both the substrate-superconductor interface and the roughness of the surfaces. A native, oxide-free interface reduced the loss due to TLSs. However, a rough

surface in the CPW gap did not cause more TLS loss, but the overall loss was significantly increased for the roughest IWR-1-endo surfaces. [doi:10.1063/1.3499608]“
“Humoral hypercalcemia of malignancy is an important cause of hypercalcemia associated with malignancies and has been rarely reported because of vulvar cancer.

A 65-year-old woman performed modified radical BTK inhibitor molecular weight vulvectomy and bilateral lymph node dissection because of vulvar cancer was referred to our clinic with fatigue and somnolence 4 months after her operation. Calcium level was 15.9 mg/dL. There was no bone metastasis,

and hypercalcemia was thought as paraneoplastic syndrome because of distant recurrence of the primary vulvar cancer.

Vulvar cancer and hypercalcemia can be seen together very rarely. However, recurrence should be kept in mind in patients with symptoms and signs of hypercalcemia.”
“This work investigates the effect of polycarbonate (PC) and montmorillonite (MMT) content on the properties and morphology of epoxy resin (EP). Izod impact strength (IS), flexural strength and critical stress intensity factor (KC) were estimated as function of modifiers content. The values of IS and KC parameters increased by respectively 150% and 90% with the addition of 5 wt % PC. Hybrid compositions containing 1 wt % MMT and 5 wt % PC exhibited the best mechanical properties. Indeed, the addition of 1 wt % MMT to EP modified with 5 wt % PC caused enhancement of IS values by 100% in comparison with neat EP. SEM micrographs revealed that the enhancement mechanism of mechanical properties might be due to extensive yielding of EP associated with the formation of stratified elongated structures.
