Thermal stimulation is an important method to promote gas production and avoid secondary hydrate formation during exploitation, but low thermal efficiency hinders its application. In this work, dissociation was carried out in synthesized hydrate-bearing sediments with 30% saturation at 6.9 MPa 9 °C. Ionic liquids, such as 1-butyl-3-methylimidazolium chloride (BMIM-Cl) tetramethylammonium (TMACl...

BACKGROUND Ionic liquid (IL) pretreatment has emerged as a promising technique that enables complete utilization of lignocellulosic biomass for biofuel production. However, imidazolium IL has recently been shown to exhibit inhibitory effect on cell growth and product formation of industrial microbes, such as oleaginous microorganisms. To date, the mechanism of this inhibition remains largely un...

The best known element of the Kobayashi-Maskawa quark mixing matrix is U„d. It is determined' by comparing the vector coupling constant Gz of nuclear beta decay to the Fermi coupling constant Gz determined from muon decay, after correcting Gz for "inner" radiative effects' that depend upon the assumed substructure of the nucleon. An accurate determination of U„d is necessary to test the unitari...

The effectiveness of BR-16A, a herbal psychotropic preparation, was investigated in shortterm memory paradigms in mice. The passive avoidance task consisted of an electric grid with a centrally located shock-free zone (SFZ). BR-16A (50-500 mg/kg) improved passive avoidance acquisition as well as retrieval in mice. BR-16A reversed scopolamine (0.3 mg/kg)-induced disruption of learning and memory...

In the microwave-assisted alcoholysis of dialkyl phenylphosphonates performed in presence suitable ionic liquids, such as [bmim][BF<sub>4</sub>] or [bmim][PF<sub>6</sub>], affording phosphonate with mixed alkoxy groups and fully transesterified product, fission function to ester-acid diacid moiety was inevitable. Moreover, [emim][HSO<sub>4</sub>], reaction co...

The quantity To is of the order of a lattice vibration period, that is, -10 1 2 sec. (Steiner 1 and Gyftopoulos have recently reported theoretical estimates of the desorption energies of halogen atoms on (110) tungsten, the values being 4. 49 eV for F, 3. 53 eV for Cl, 2.94 eV for Br, and 2.45 eV for I.) Equation 1 is plotted in Fig. IX-l for T = X 10 1 2 se and several values of E d . It can b...
