Dye-sensitized solar cells (DSSCs) are one of the most promising organic photovoltaics. The optimized efficiency of a tandem cell combined with both n- and p-type DSSCs was theoretically predicted to be 43%. The bottleneck for reaching the optimized performance is limited by the p-type half-cell...
We synthesized two highly efficient red phosphorescent Ir(III) complexes, bis[2,3-diphenylquinoxalinato-N,C2′]iridium(III) pyrazinate (dpq)2Ir(prz) (1) and bis[2,3-diphenylquinoxalinato- N,C2′]iridium(III) 5-methylpyrazinate (dpq)2Ir(mprz) (2), which are both based on the use of 2,3-diphenylqu...
2,3-diphenylquinoxaline (DPQ) and 2,3-diphenylquinoxaline N,N′-dioxide (DPQDO) (also known as 2,3-diphenylquinoxaline 1,4-dioxide) were synthesized, and their infrared and Raman spectra were measured. The structural stability and the vibrational spectra of the two quinoxaline molecules were inv...
Alzheimer’s disease (AD) is a neurodegenerative disease characterized by a progressive loss in memory and cognitive abilities. One of the key pathologic features of AD is the accumulation of beta amyloid (Aβ). Somatostatin has been shown to regulate neuronal neprilysin activity, a key enzyme i...
6-Oxo and 6-thio analogs of purine were prepared based on the initial activity screening of a small, diverse purine library against Mycobacterium tuberculosis (Mtb). Certain 6-oxo and 6-thio-substituted purine analogs described herein showed moderate to good inhibitory activity. N9-substitution ...
Synthesis of a series of 2-(arylmethylthio)-6-ethyl-7H-pyrrolo[2,3-d]pyrimidin-4-ol and their cytotoxic activity on HCT-116 and A-549 cell lines using MTT assay is reported. The 6-ethyl-2-((4-fluorobenzyl)thio)-7H-pyrrolo[2,3-d]pyrimidin-4-ol 3d is the most active compound on HCT-116 with IC50 o...
An up-to-date review of the range of methods available for the synthetic manipulation of carbon and heteroatom-based substituents on the heterocyclic and/or carbocyclic rings of pyridines, quinolines, and isoquinolines is presented in this chapter. The preparation and reactions of organometallic...
Reactions of model sulfur centred nucleophiles with 4-nitro-, 4-phenylsulfonyl- and 4-cyano-tetrafluoropyridine gave products arising from substitution of the nitro- and sulfonyl substituent or ring fluorine respectively. Ring fused products are formed upon reaction of 4-cyano-tetrafluoropyridin...
Dehydrobutyrine is an amino acid that is present in a range of peptide natural products. Reaction of pentafluoropyridine with threonine and subsequent E1cb-type elimination allowed the preparation of novel dehydrobutyrine-containing amino acids under mild conditions.
2,3,5,6-Tetrafluoro-4-nitrosopyridine has been synthesised via oxidation of 4-amino-2,3,5,6-tetrafluoropyridine with peroxytrifluoroacetic acid in dichloromethane. It reacts with diphenyldiazomethane in light petroleum to give, inter alia, C,C-diphenyl-N-(tetrafluoro-4-pyridyl)nitrone.
Publisher SummaryThis chapter describes the assay method, purification procedure, and properties of N5-formyltetrahydrofolic acid glutamic acid transformylase from hog liver. The method is based on the measurement of the tetrahydrofolic acid formed. The assay employed for tetrahydrofolic acid de...
A 1,2-dicarba-closo-dodecaboranyl derivative (8) and its disodium salt (9) were prepared from 4-aminobenzoic acid (1). The water solubility and the biological data (toxicity and cell-uptake) of the disodium salt (9) were identified to be enough for clinical trial.

In this paper we analyze informativeness of Z-numbers in terms of measures of specificity. We introduce a human-like concept of specificity measure of Z-number as a generalization of specificity measure of a fuzzy set. According to this concept, a human being assigns weights to measure importanc...
A Z-scheme g-C3N4/V2O5 heterostructure was freshly applied to the removal of indoor noxious gases. In addition, to continuously remove noxious organic gases with minimal photocatalyst loss in a steady-flow chamber, the Z-scheme g-C3N4/V2O5 photocatalytic system having a three-dimensional monolit...
Developing highly active photocatalysts towards effective microorganism inactivation is a green and energy-smart strategy in response to the growing demands to water quality under the background of the water crisis. Here, a vertical face-to-face heterojunction is fabricated by horizontally assem...
Rationale and ObjectivesTo show that water and iodine two-material decomposition images from dual-layer dual-energy spectral X-ray computed tomography (DECT) can be used to separate intravascular iodine contrast from simultaneously administered oral tantalum, tungsten, or rhenium contrast in an ...
Aluminum foam sandwich (AFS) structures are suitable for impact protection in lightweight structural components due to their specific energy absorption capability under compression. However, tailoring the deformation patterns of the foam cells is a difficult task due to the randomness of their i...
In this study, an efficient and durable photocatalyst composed of Bi12GeO20 and γ-Bi2MoO6 through like Z-scheme mechanism was successfully obtained by heat treatment. The as-prepared Z-scheme 40γ-Bi2MoO6/Bi12GeO20 heterostructure presents the superior photocatalytic performance for degrading M...
Levofloxacin—a fluoroquinolone antibiotic—is a potential wastewater contaminant generated by pharmaceutical industries. Novel one-dimensional disilver dimolybdate (Ag2Mo2O7) structures were developed to form a heterojunction with thin nanosheets of MoS2 on the surface of Ag2Mo2O7. A photocatal...
