The resultant amine-cured thermosets, meanwhile, exhibited enhanced thermal stability, flexural strength, storage modulus, and adhesion strength at the expense of a 5% increase in the coefficient of thermal expansion. Exceeding the stoichiometric quantity of the polyurethane precursor, however, reduced the thermal stability and modulus but further increased the coefficient of thermal expansion.

“The fantastic ferroelectric response to the magnetic field observed in Ca(3)CoMnO(6) compound, where

the ferroelectricity is driven by the collinear magnetism, is investigated by using Monte Carlo simulation based on a one-dimensional elastic Ising model. The microscopic domain structures of spins and ionic displacements are evaluated at different temperatures under different external magnetic fields. It is revealed that the up-up-down-down Cytoskeletal Signaling inhibitor (up arrow up arrow down arrow down arrow) spin domains clamped with the domains of ionic displacement are responsible for the exotic ferroelectric behavior upon different magnetic fields in the low temperature range.”
“For the modification of an electrospun poly (vinylidene

fluoride-co-hexafluoropropylene) (PVDF-HFP) membrane for its potential use as an electrolyte or separator in lithium batteries, poly(ethylene glycol) dimethacrylate (PEGDMA) was introduced into a polymer solution for electrospinning. A post heat treatment of the as-electro-spun membrane at an elevated temperature was performed for PEGDMA polymerization, and this was verified by Fourier transform infrared

spectroscopy. The results showed that no significant variations in the membrane morphology were detected when a small amount of PEGDMA (PVDF-HFP/PEGDMA mass ratio = 4/1) was incorporated. This electrospun membrane after heat treatment at 130 degrees C for 2 h exhibited a significantly higher tensile strength (6.26 +/- 0.22 MPa) than that of an electrospun PVDF-HFP membrane (3.28 +/- 0.35 MPa) without PEGDMA. The porosity Selleckchem CAL 101 and liquid absorption of the electrospun PVDF-HFP/PEGDMA (4/1) membrane were 70.0 +/- 1.6% and 267 +/- 11%, respectively, lower than those of the electrospun PVDF-HFP membrane (76.5 +/- 0.3% and 352 +/- 15%) because of the introduction of PEGDMA.

“The characteristics of decamethylcyclopentasiloxane (DMCPS) and trifluoromethane (CHF(3)) electron cyclotron resonance plasmas for depositing F-SiCOH low dielectric constant films were investigated by quadrupole mass spectrometry and optical emission spectroscopy. The radicals in the plasma come from the dissociation of DMCPS and CHF(3) molecules and the recombination of active radicals.
