Topochemical transformations of crystalline Na5P3O10 · 6H2O, Li5P3O10 · 5H2O, and NaLi4P3O10 · 4H2O, amorphous Na2Li3O10 · 4.3H2O and mixed amorphous-crystalline Nao.9Li4.1O10 · 4.4H2O were studied by DTA, TG, DTG, 1RS, XRD, and TLC methods in the temperature range 20–950°C. In all cases,...
Placer gold particles derived from epithermal deposits display distinct morphological and compositional features compared with particles from mesothermal systems. Here, it is hypothesized that the chemical composition of primary gold derived from different deposit types is a principle factor aff...
A new strategy is developed for construction of the mixed molecular nanostructures from folic acid (FOA), a targeting agent, and deferrioxamoine-Ga(III), (DFO-Ga(III)), a theranostic agent, on gold-mercaptopropionic acid surface, Au-MPA. The strategy is focused to achieve a system in which all t...
Cellulose acetyl derivatives were examined for the selective recovery of Au(III) from acidic chloride solutions as an adsorbent, and cellulose acetate fibers (CAF) were found to be effective for the separation of Au(III) from other metal ions, including the precious metal ions Pt(IV) and Pd(II)....
A fluorescent probe for gold ion, Au(III), is developed based on Au(III)-induced disaggregation of AIEgen for the first time. Although many contributions have been made to develop fluorescent probes for sensing Au(III), many of them were faced with limitations such as complex mechanism, slow res...
Gold(III) compounds have long been investigated for anti-cancer treatment. However, clinical use has often been hampered by their poor stability in solution. In the design of physiologically stable anticancer gold (III) complexes, promising tetrapyrrole derivatives such as phthalocyanines are ra...
Colorectal cancer (CRC) is the third most common cancer diagnosed worldwide. The limitations of cisplatin-based chemotherapy have prompted intense interest among scientists to search for alternative metal-based anticancer medicines. Gold(III) complexes have been among the most widely investigate...
An efficient heterogeneous gold-catalyzed oxidative cross-coupling of propargylic acetates with arylboronic acids has been developed that proceeds smoothly in the presence of Selectfluor and provides a general and powerful tool for the preparation of various valuable α-arylenones with moderate ...
Detection of trace level gold (Au(III)) ion with rapid and cheaper colorimetric detections was performed. Herein, the organic ligand of 4-aminoantipyrine (AAP) was facilely supported onto the mesoporous silica nanospheres as a scaffold. The 4-aminoantipyrine (AAP) was used as a reducing and capp...
The solid state molecular structure of 2,3-dihydroxyquinoxaline (DHQ) has been studied using X-ray single crystallography. The equilibrium geometry of six possible DHQ isomers have been calculated using the B3LYP/6-311++G(d,p) method in order to predict the most stable gas-phase isomer. The effe...
Isobaric vapor-liquid equilibria for the binary systems tert-butyl alcohol + water, and tert-butyl alcohol + 1-ethyl-3-methylimidazolium dicyanamide ([emim][DCA]), as well as the vapor-liquid equilibria for the tert-butyl alcohol + water + [emim][DCA] ternary system, have been obtained at 100 kP...
A general preparation of 2-substituted indoles starting from functionalized 2-alkynylanilines has been developed. This base mediated reaction has also been used to synthesize the heterocyclic core of the marine alkaloid hinckdentine A. Furthermore the reaction was successfully adapted to the sol...
A facile and efficient base-mediated protocol for debromination of vic-dibromides in perfluoroalkyl(aryl) compounds in aqueous medium has been demonstrated. With mild reaction conditions, the developed strategy has a good substrate scope and electron-deficient olefin products were obtained in go...
We provide the first causal evidence on whether e-cigarette advertising on television and in magazines encourages adult smokers to quit. We find the answer to be yes for TV advertising but no for magazine advertising. Our results indicate that a policy banning TV advertising of e-cigs would have...
BackgroundJUUL e-cigarettes are popular among youth. However, it is unknown whether adolescents understand that 5% JUUL pods contain a high nicotine concentration or consider JUULs to be e-cigarettes.
A new rigid tetraaryl-substituted benzene, 1,2,4,5-tetra(p-hydroxyphenyl)benzene (C30H22O4, TetHPB), has been synthesized. Its crystalline hydrate C30H22O4·2H2O (1) and the inclusion compound of its anions with the tetrapropylammonium cations, [(C30H21O4)2H]−·(n-C3H7)4N+ (2), have been prepare...
We have explored the synthesis of compounds that have good affinity for both μ- and δ-opioid receptors from the (αR,2S,5S) class of diaryldimethylpiperazines. These non-selective compounds were related to opioids that have been found to interact selectively with μ- or δ-opioid receptors as ...
Benzene, a ubiquitous human carcinogen, forms DNA adducts through its metabolites such as p-benzoquinone (p-BQ) and hydroquinone (HQ). N2-(4-Hydroxyphenyl)-2′-deoxyguanosine (N2-4-HOPh-dG) is the principal adduct identified in vivo by 32P-postlabeling in cells or animals treated with p-BQ or HQ...
The vibrational spectra and corresponding vibrational assignments of 2-(3-methoxy-4-hydroxyphenyl)benzothiazole is reported. Single crystal XRD data of the title compound is reported and the orientation of methoxy group is cis to nitrogen atom of the thiazole ring. The phenyl ring breathing mode...
It was the first report that the concentrated hydrolyzates from the enzymatic hydrolysis of dilute NaOH (3 wt%)-soaking rice straw at 30 °C was used to form [Bmim]PF6-hydrolyzate (50:50, v/v) media for bioconverting ethyl 4-chloro-3-oxobutanoate (COBE) into ethyl (R)-4-chloro-3-hydroxybutanoate...
