A short and simple synthesis of tetrahydropyrimidine derivatives were accomplished in good to excellect yields at room temperature by the reaction of dimethylacetalynedicarboxylate, aniline, and formaldehyde in the presence of 5 mol% of molecular iodine at room temperature in ethanol for 5 min.关键...
The weight of ideal UiO-66 at 350 °C is 220.2% which agrees with the chemical formula of Zr6O6(BDC)6, In contrast, the weight of defective UiO-66 at 350 °C is below 220.2% suggesting the deficiency of BDC linkers. The defective UiO-66 takes the formula of Zr6O6+x(BDC)6-...
the addition of diluents, the temperature of the battery rises sharply during the puncture test to damage the battery structure due to the enhanced reactivity of anions in LHCE. The reaction between Li salts and Li metal anode in concentrated electrolytes could potentially release a large amount o...
The hyperpolarizability of this molecule is much bigger than that which could be deduced by combining results for nitrobenzene and aniline (see Table 1). This enhancement of the second-order nonlinearity is generally interpreted in terms of internal charge transfer in a molecule containing both ...

Newly growing evidence highlights the essential role that epitranscriptomic marks play in the development of many cancers; however, little is known about the role and implications of altered epitranscriptome deposition in prostate cancer. Here, we show t
Phase Transitions in Mesomorphic BenzylideneanilinesWe have synthesized(1) 35 compounds of structural formula where n and m take on values from 1 to 7 and 4 to 8 respectively. (2) We have studied the phase behavior and identified many of the mesomorphic phases of these compounds by means of...
Furthermore, the activity, cytotoxicity, apoptosis, and angiogenic potential of PMVECs were assessed to gauge cell injury. The interaction between Elk1 and Fcgr2b was also examined to confirm their regulatory relationship. Results In the context of LPS-induced ARDS and PMVEC injury, Fcgr2b ...
At the end of crystallization, the hydrolysis of DMF stops together with the stabilization of pH. The main non-crystalline by-product of MIL-53 synthesis is a mixture of soluble dimethylammonium salts with brutto-formula [((CH3)2NH2)x(NO3)x-1]+[NO3]−. Method development and outlook ...
2a, iii). Also note that symmetric azoxy compound shows two peaks with different UV/vis spectra according to HPLC, due to the spontaneous mutual E/Z isomerization of the N = N bond1,5). Given that 1 had mutual C4 E/Z isomerization and that 3′ had the same molecular formula as...
