PES-C/PTFE composite was implanted with 110 keV protons in four doses of 1×10~14 ions/cm2, 5×10~14 ions/cm2, 2.5×10~15 ions/cm2 and 1.25×10~16 ions/cm2, and the frictional and wear properties of the implanted composites were studied.
The effects of solvent polarity and protonic solvent on the fluorescent properties of hydroxyethyl cellulose(HEC)/Eu(Ⅲ),methyl cellulose(MC)/Eu(Ⅲ) and carboxymethyl cellulose(CMC)/Eu(Ⅲ) complexes were investigated by fluorescent spectroscopy to reveal the interaction between the fluorescent substance and the solvent on the microcosmic level.
When catalyzed by the compound catalyst of zinc lactate and taurine,the intrinsic viscosity ranged between 01068 dL/g and 01357 dL/g,higher than that catalyzed by taurine (01036 dL/g) and lower than that by zinc lactate (01507 dL/g). No obvious synergistic effect was found between metal Lewis acid catalyst and protonic acid catalyst.
The structure of the titled compound is determined by infrared spectrum(IR), proton nuclear magnetic resonance (HNMR), and mass spectrum (MS) and elemental analysis (EA).
It was suggested that the mechanism for the eruption of heat was that La3+ ion damages the outer cell membrane and increases its permeability and the proton-electron potential energy across the cell membrane was reduced or couldn't even be initiated.
We systematically calculate the ground state properties of superheavy even-even nuclei with proton number Z=94-118.
Fabrication and performance of PEN SOFCs with proton-conducting electrolyte
It also increased the proton-conducting rate and improved the performance of SOFCs due to the reduction of membrane thickness and good contact between electrolyte and electrodes.
The nonselective, selective and double-selective spin-lattice relaxation rates of some protons in huperzine E were acquired in the absence and presence of AchE at a concentration ratio of [ligand]/[protein] = 1: 0.005.
The enhancements of selective relaxation rates of these protons were obvious after adding AchE.
The molecular motional correlation times of two pairs of protons, H-1a/H-1b and H-2/H-3, in the bound state at T = 298 K were 11.7 and 9.46 ns respectively, while they were 27.7 and 35.2 ps in the free state.
Nonexponential Diffusion Extinction of Spin Echo from Water Protons in Wheat Root
The function of bacteriorhodopsin in Halobacterium salinarum is to pump protons from the internal side of the plasma membrane to the external after light excitation, thereby building up electrochemical energy.
Zinc presumably blocks the entrance of the D-protonic channel opening into the inner aqueous phase.
Effect of the Structure of a Proton-Hydrate System of Hydrogen Bonds on the Protonic Conductivity in Crystals of the Flavianic A
It is shown that the introduction of 20-25 mol % PbF2 leads to a crossover from the protonic conductivity to the unipolar fluorine ionic conductivity ().
Influence of the order of introduction of protonic acids on the formation of active complexes in the Ni(PPh3)4/BF3 · OEt2 cataly
The influence of the order of introduction of promoters (complex protonic acids) on the formation of active complexes in the Ni(PPh3)4/BF3 · OEt2 catalytic system and the activity of these systems in ethylene oligomerization have been studied.
