The concentrations of bioaerosols near pretreatment facilities are often higher than those near activated-sludge aeration tanks in wastewater treatment plants (WWTP). The reason for this difference is not yet clear and the differences between the cha

Volatile organic compounds (VOCs) emitted from smoldering mosquito coils containing various atomic hydrogen/carbon (H/C) ratios in different relative humidity were examined. The concentrations of individual VOCs were determined using a preconcentrato

The substituent effect on azo-hydrazone tautomerization of 1-arylazonaphthen-ols is studied by means of NMR analysis. Among the 13C chemical shifts, the C(2) of this series compound is the most sensitive to the variation in the nature of substituent

An electron-ionization (EI) mass spectra of a series of 1-arylazonaphthalen-2-ols was obtained for studying the substituent effect on the fragmentation. The correlation between the ratio, molecular ion and fragment ion, and Hammett’s constants is a

A series of arylmethylene-malononitriles and malonates were prepared from the condensation of arylaldehydes and malononitriles and malonates, respectively. The function of substituents on the carbon-13 chemical shifts of the Cα and Cβ was studied.

The treatment of a series of 1-aryl-2,2-dihalocyclopropanes with t-BuOK at −10 °C produces the corresponding 1-aryl-2-halocyclopropenes, which react with cyclopentadiene to produce fairly good yield of [4+2]-cycloaddition products with more than 9

The electrophilic substitution of 3-aryl-4- phenylsydnones, 3-arylmethylsydnones and 3-phenylethyl- sydnone are studied in order to understand extend of dual nature of the sydnone ring. In the reaction, the nitronium cation is more reactive toward to

Incense was burned in a controlled environment, in order to understand the effect of relative humidity on polycyclic aromatic hydrocarbons (PAHs) emissions from smoldering incense. The concentrations of individual PAHs were determined using the GC/MS
