Three new POM-based compounds, with formulae [Na0.63Ag3(Htba)2.37(tba)0.63(H2O)2(PMo12O40)]·4H2O (Ag3PMo), [Ag4(Htba)4(H2O)2(PMo12O40)](NO3)·H2O (Ag4PMo), and [Ag3(Htba)2(tba)(PW12O40)0.5](NO3)0.5·13H2O (Ag3PW), were prepared a 3-(4H-1,2,4-triazol-4-yl)benzoic acid (Htba) ligand, Keggin-type anions ([PMo12O40]3–/[PW12O40]3–), silver ion (Ag+). The structural features of these compounds are particularly different from the multinuclear subunits, which [Ag3(tba)3] clusters in Ag3PMo,...
The introduction of transition metal (TM) ions into polyoxometalates (POMs) cannot only bring about interesting structural diversities but also enable changes in properties. However, TM-containing Silverton-type polyoxomolybdates are still lacking terms diversity and application development. Herein, two Zn(II)-containing {UMo12O42}-based polyoxomolybdates, H1.89Na4.11(H2O)9Zn[UMo12O42]·4.5H2O (Zn-1) H1.8Na4.2(H2O)12Zn[UMo12O42] (Zn-2) were hydrothermally synthesized, demonstrating a...
N-heterocycle compounds are the crucial scaffolds present in natural products, synthetic molecules, agricultural chemicals, and pharmaceuticals. Hence, development of green catalytic systems for constructing N-heterocycles has been a focused topic organic synthesis industrial catalysis. Polyoxometalates (POMs) polynuclear metal–oxygen clusters with structural diversity physicochemical properties. POMs possess advantageous properties such as adjustable acidity, redox properties, high thermal...

An optical wireless underwater communication simulation model is proposed, which serves as the theoretical of simulator for AUVs. Various parameters that will influence light distribution and performance are explored. As a preliminary result, this paper focuses on propagation in water, channel characteristics. Given transmitter water turbidity, provides received power every position. With calculation noise receiver, an estimation data rate capacity provided. This research aims at building...
Two Mn(II)-bridged Silverton-type {UMo12O42}-based polyoxomolybdates with different three-dimensional structures, Na6(H2O)12[Mn(UMo12O42)] (NaMn) and (NH4)2[K2Na6(μ4-O)2(H2O)1.2Mn(UMo12O42)]·4.6H2O (KMn), were hydrothermally synthesized further characterized, demonstrating a feasible strategy for the assembly of polyoxomolybdates. Additionally, NaMn is demonstrated to be good heterogeneous catalyst in condensation cyclization reaction hydrazines 1,3-diketones, range valuable pyrazoles...

We report the first highly enantio- and diastereoselective three-component Povarov reaction between anilines aldehydes catalyzed by a chiral amine catalyst. A wide variety of substituted tetrahydroquinolines were obtained with moderate to good yields excellent enantioselectivity diastereoselectivity (up 99% ee >95:5 dr) under conditions. Furthermore, intermediates could be efficiently converted other valuable building blocks.
Efficient Pd-catalyzed <italic>ortho</italic>-olefination of Tyr residues by employing silanol as a directing group with high chemo- and site-selectivity was developed. Orthogonal protection strategies were also successfully applied to SPPS.
Peptide modification provides opportunities to afford peptides with designed functions. Among the proteogenic amino acids, tryptophan represents an ideal and attractive target for peptide because of exclusive chemical reactivity its unique indole structure. Herein, we reported C2 position-selective transition-metal-free approach derivatives tryptophan-containing by triazine via triflic acid activation that incorporated functional group could act as orthogonal handle further bioconjugation...
To investigate the effect of stereotactic body radiation therapy (SBRT) on pulmonary oligometastases and to analyze clinical factors dose parameters affecting local recurrence-free survival (LRFS) overall (OS).This study retrospectively enrolled a total 84 patients (148 lesions) treated in our department from May 2015 November 2018. Pulmonary was defined as up 5 metastatic lesions lung with both primary tumor any extra-thoracic metastases being controlled. Patients receiving BED10...
A convenient strategy for the diastereoselective synthesis of α,β-diamino diacid derivatives bearing congested vicinal acyclic tetrasubstituted stereocenters via catalytic Mannich-type reactions azlactones and 2-aminoacrylates was established. diverse set were synthesized in good to excellent yields diastereoselectivities.

Methionine (Met) offers a valuable handle to achieve peptide chemical modification owing its unique thioether functional group. In contrast with cysteine, the site-selective functionalization of hydrophobic and redox-sensitive motif on peptides is still challenging, strategies for diversification Met residue are rarely disclosed. Herein we report transition-metal-free redox-neutral approach substrate diversity, which could be applied synthesize cyclic peptides.

Abstract Staphylococcal food poisoning is one of the most common foodborne diseases worldwide; it results from ingestion staphylococcal enterotoxins (SEs) in food, mainly Staphylococcus aureus. This study investigated statistical relationships among morphological enumerations food-derived S. aureus and production SEs using different methodologies. Food samples naturally contaminated with coagulase-positive were submitted for enumeration on Baird-Parker (BP) agar, Rabbit Plasma Fibrinogen...
