This paper reports an efficient, odorless and one-pot procedure for the synthesis of benzyl alkyl disulfides using mixtures thiourea, halides, thiocyanates. The reactions carried out in water with assistance microwave enable a time-saving process.
In continuation of our program aimed at the discovery and development natural product-based insecticidal agents, a series novel nereistoxin derivatives containing phosphonate were synthesized characterized by 31 P, 1 H, 13 C NMR HRMS.
Nerve agents (NAs) are notorious chemical warfare that pose a serious threat to national security and public health. The total number of theoretical chemicals NAs their degradation products (DPs) exceeds 410 000, according 1.A.01–1.A.03 in the Schedules Chemicals Chemical Weapons Convention, which poses great challenges for identification verification. A three-step integrated untargeted screening strategy was developed based on high-resolution mass spectrometry. First, an extensible homemade...
The threshold for the transition between Autler–Townes splitting (ATS) and electromagnetically induced transparency (EIT) is studied through examining dynamics of decaying dressed states, which are derived from effective Hamiltonian. It found that corresponds to suppression Rabi oscillation populations by relaxation as coupling field becomes weak. Moreover, ATS EIT belong two different regimes, former being in non-perturbation regime, where there coherent states coupled field. By contrast,...
In2O3/C3N4 composites were prepared with In(OH)3 and C3N4 by ball-milling calcination. The samples characterized TG, XRD, TEM, XPS, FT-IR, DRS, EIS, Photocurrent Photoluminescence measurements. Photocatalytic performance of the catalyst was measured degradation test methyl orange (MO). photocatalytic is higher than that In2O3 C3N4. photocurrent response to In2O3/C3 N4 (17.3%) 11.3 times 183.1 as high pure C3N4, respectively. enhanced activity attributed separation migration efficiency...
Based on our experimental observations of the resonant stimulated Raman gain and loss spectra in Rb atomic vapor, we propose an alternative interpretation electromagnetically induced transparency (EIT). We find that, presence a coupling field, probe beam can exhibit both depending frequencies incident beams. The coexist Doppler-broadened system, leading to polarization interference between atoms different velocities, with sharp transition from as probe-field frequency is scanned. use concept...
Generalized quartic dispersion Kerr solitons (GQKSs) represent a unique soliton family, which are solutions to the generalized Schrödinger equation with interplay between nonlinearity and combination of quadratic dispersions. The well-known pure (PQSs) exactly within special case this occurring in presence negative quartic-only dispersion. Here, we report on first experimental generation GQKSs from fiber laser investigate their temporal spectral characteristics. We find that features closely...
Novel nereistoxin derivatives containing phosphonate were synthesized and characterized via 31P, 1H 13C NMR HRMS. The anticholinesterase activity of the compounds was evaluated on human acetylcholinesterase (AChE) using in vitro Ellman method. Most exhibited good inhibition acetylcholinesterase. All these selected to assess their insecticidal (in vivo) against Mythimna separata Walker, Myzus persicae Sulzer Rhopalosiphum padi. tested displayed potent three species. Compound 7f all insect...
Rationale Organophosphorus nerve agents are highly toxic because they inhibit acetylcholinesterase activity, thereby causing a series of symptomatic poisoning. Upon entering the body, bind active amino acid residues to form phosphonylated adducts. A potentially beneficial method for specific verification exposure is based on albumin adducts, which have half‐life 18 days. This appears be more effective than fluoride reactivation method, acetylcholinesterase. Methods After human serum nine...
The effects of Doppler broadening on Autler-Townes (AT) splitting in six-wave mixing (SWM) are investigated by the dressed-state model. We analyze velocities at which atoms resonance with dressed states through frequency shifting and find that, depending wave-number ratio, there may be two resonant can originate from one or different states. Based this model, we discuss a novel type AT doublet SWM spectrum, where macroscopic play an important role. Specifically, existence peaks requires...
GRAPHICAL ABSTRACT
We measure the absorption and dispersion in a Doppler-broadened Λ-type three level system by resonant stimulated Raman spectroscopy with homodyne detection. Through studying dressed state energies of system, it is found that satisfy Kramers–Kronig relation. The spectra calculated employing this relation agree well our experimental observations.
Based on Akaike's information criterion (AIC) for a coherently driven ensemble of cold rubidium atoms, we study the crossover between electromagnetically induced transparency (EIT) and Autler–Townes (AT) splitting from dispersion as well absorption viewpoint. We find that signal is more sensitive than signal, showing pronounced features in Akaike per-point weights spectrum, which provides cleaner way discerning EIT AT splitting.
The developed synthetic procedure is economical and environmentally friendly. It also avoids using toxic organic solvents, an oxidant or a reductant.
