TL;DR: Excess volumes of binary liquid mixtures of N,N-dimethylformamide with toluene, ethylbenzene, chlorobenzene, bromobenzenes, nitrobenzenes, and aniline at 303.15 and 313.15 K have been measured with a dilatometer.
Abstract: Excess volumes of binary liquid mixtures of N,N-dimethylformamide with toluene, ethylbenzene, chlorobenzene, bromobenzene, nitrobenzene, and aniline at 303.15 and 313.15 K have been measured with a dilatometer. Excess volumes are negative for the systems of N,N-dimethylformamide with toluene, ethylbenzene, chlorobenzene, bromobenzene, and aniline. The excess volumes are positive for the system N,N-dimethylformamide with nitrobenzene at 303.15 K and show a change in sign at 313.15 K

TL;DR: A flow-through optical absorption detector for HPLC was constructed using a novel deep-UV light-emitting diode as radiation source with a peak emission wavelength of 255 nm and tested with three substances, namely nitrobenzene, benzoic acid and methyl benzoate.
Abstract: A flow-through optical absorption detector for HPLC was constructed using a novel deep-UV light-emitting diode as radiation source with a peak emission wavelength of 255 nm. For measuring the transmitted intensity (a property correlated to Transmittance) a special UV-sensitive photodiode was employed. Besides the power source, no optical or electronic components other than an inexpensive operational amplifier and a few passive components were necessary. The performance of the detector was tested with three substances, namely nitrobenzene, benzoic acid and methyl benzoate, which were separated by gradient elution using an acetonitrile/water mixture and tetrabutylammonium hydrogensulfate as pH-buffer. Calibration curves for concentrations between 1.6 µg·mL−1 and 400 µg·mL−1 (nitrobenzene) and 8 µg·mL−1 and 2.5 mg·mL−1 (benzoic acid and methyl benzoate) were determined and coefficients of determination, r2, of 0.9945, 0.9972 and 0.9996 were obtained for quadratic curve fits for the 3 compounds respectively. Relative standard deviations (n = 7) for peak areas were determined as 0.35% (nitrobenzene, 80 µg·mL−1), 0.27% (benzoic acid, 400 µg·mL−1) and 0.83% (methyl benzoate, 200 µg·mL−1). The lower limits of detection were found to be 750 ng·mL−1, 5.8 µg·mL−1 and 12 µg·mL−1 for nitrobenzene, benzoic acid and methyl benzoate respectively.

TL;DR: A highly luminescent metal-organic framework (MOF) constructed by a rare dendritic multicarboxyl acid with a pyrene chromophore was synthesized successfully.
Abstract: A highly luminescent metal–organic framework (MOF) constructed by a rare dendritic multicarboxyl acid with a pyrene chromophore was synthesized successfully. The fluorescence intensity of the MOF in DMF is obviously stronger than that in other common solvents such as acetone, CH2Cl2, CHCl3, cyclohexane, toluene, pyridine and THF. This particular fluorescence response to DMF is significant in sensing DMF. In addition, this MOF can sense nitrobenzene effectively. Low detection limit and good reproducibility make this material promising for explosive substance detection.
