Diiron dithiolate complexes have received special attention because of their structural similarity to the active site [FeFe]-hydrogenases, which are most efficient and fastest catalysts for generation dihydrogen in nature. Recently, we established a novel way prepare phosphine-substituted diiron aza- oxadithiolate complexes. Reaction Fe2(μ-SCH2OH)2(CO)6 several phosphine ligands L (L = PPh3, PPh2(2-C5H4N), P(C6H4-4-CH3)3) affords intermediate Fe2(μ-SCH2OH)2(CO)5L, while situ reacts with...
Zinc or swim: Arylation of benzyl trifluoroacetates with arylzinc reagents in the presence β-hydrogen atoms were realized under mild conditions. Both electron-rich and electron-deficient arene substrates successfully arylated. This arylation method could offer a very versatile synthetic route to access series diversity-oriented diarylalkane motifs. TFA = trifluoroacetyl. Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but...
Vacuum freeze drying (VFD) combined with thermal can solve the defects of vacuum freeze-dried chives, such as faint flavor, unpleasant color, and taste. However, mechanisms for enhancing reducing lightness, improving taste through remain to be explored. In this study, effects hot air drying, infrared catalytic (VFD-CIRD) on flavor quality characteristics chive leaves stems were investigated. The results demonstrated that VFD-CIRD had richest attributed key aromas hydroxyacetone...
We derive an analytical propagation expression of the finite energy Airy-Hermite-Gaussian beam propagating in a uniaxial crystal orthogonal to optical axis, and calculate numerical examples investigate influences distance ratio extraordinary refractive index ordinary on profile. In addition, we also examine intensity distribution crystals at different observation sections. Our research shows that initial profile remains nearly invariant for short crystal. However, as continues increase,...
Acylhydrazones formation has been widely applied in materials science and biolabeling. However, their sluggish condensation rate under neutral conditions limits its application. Herein, indolines with electron-donating groups are reported as a new catalyst scaffold, which can catalyze acylhydrazone, hydrazone, oxime via an iminium ion intermediate. This type of showed up to 15-fold enhancement over the traditional aniline-catalyzed reaction at conditions. The identified indoline was...
ABSTRACT The selective binding of some drug to DNA has been explored in this study elucidate the structure-function relationship anticancer agent. In case behavior dacarbazine [5-(3,3-dimethy-1-triazenyl)imidazole-4-carboxamide; DTIC], it was found that causes significant decrease absorption intensity DTIC without any shift peak position. Besides, nuclear magnetic resonance (NMR) shows only slight upfield observed upon addition DNA. These results as well our nanostructural by atomic force...
With the grid-connected ratio of renewable energy growing up, development storage technology has received widespread attention. Gravity storage, as one new physical technologies, outstanding strengths in environmental protection and economy. Based on working principle gravity through extensive surveys, this paper summarizes various types technologies existing world their status. The advantages shortcomings different are compared depth , so to provide reference for technology.
In this paper, we introduce a new method to calibrate the absolute sensitivity of soft X-ray streak camera (SXRSC). The calibrations are done in static mode by using small laser-produced source. A calibrated CCD is used as secondary standard detector monitor source intensity. addition, two sets holographic flat-field grating spectrometers chosen spectral discrimination systems SXRSC and CCD. obtained comparing signal counts output Results show that spectrum covers range from 200 eV 1040 eV....
A polarization point diffraction interferometry (PPDI) system, adopting a specially designed even aspheric quarter-wave plate (EAQWP) in the test path, is proposed for low-reflectivity and high-numerical-aperture spherical surface testing. In terms of mirror measurement, obtained poor fringes contrast, which can significantly affect measurement accuracy, be improved by characteristic EAQWP. Simultaneously, wavefront distortion, especially larger high-numerical apperture (NA) greatly reduced...
