Phenol biodegradation by Ralstonia eutropha was modeled in different culture modes to assess phenol feeding in biotechnological depollution processes. The substrate-inhibited growth of R. eutropha was described by the Haldane equation with a Ks of 2 mg/L, a Ki of 350 mg/L and a mumax of 0.41 h(-1). Furthermore, growth in several culture modes was characterized by the appearance of a yellow colo...

Bicarbonate enhances the transformation of phenol upon irradiation of hematite, and phenol nitration upon irradiation of both nitrate and nitrite. Hematite under irradiation is able to oxidise the carbonate ion to the CO3-. radical, which in turn oxidises phenol to the phenoxyl radical faster compared to the direct photo-oxidation of phenol by hematite. The formation of CO3-. from hematite and ...

Synthesis of 2-(4-Acetyl-phenyl)-4-nitro-isoindole-1, 3-dione chalcones were performed by fusion 3-nitro phthalic anhydride with p-aminoacetophenone. Then the later was grinded different aromatic aldehydes in presence sodium hydroxide to produce new derivatives A3-10 without using any solvent formation N-arylphthailimide confirmed FTIR,1HNMR, 13CNMR spectroscopy and all final compounds tested f...

Phenol was extracted from sebacic acid wastewater (SAWW) using liquid-liquid extraction in batch as well as serial modes by applying different solvent: SAWW (1:250 5:250, v/v). Alcohols (1-hexanol, 1-heptanol, and 1-octanol), castor oil and Aliquat-336® were used for phenol extraction. In a typical extraction experiment involving shaking and allowing for phase separation, phenol (75-96%) can be...

a series of 2-(4-nitro-1-imidazolylmethyl)-1,3,4-oxadiazole, 1,3,4-triazole and 3-(4-nitro-1-imidazolylmethyl)-1,2,4-triazole derivatives were synthesized and tested for their antimicrobial activity. some of the tested compounds were active against staphylococcus aureus, staphylococcus epidermidis, bacillus subtilis, clostridium difficile, aspergillus niger and cryptococcus neoformans.

Molecular devices are reported utilizing active self-assembled monolayers containing the nitroamine @28-amino-4,48-di~ethynylphenyl!-58-nitro-1-benzenethiolate# or the nitro compound @4,48-di~ethynylphenyl!-28-nitro-1-benzenethiolate# as the active components. Both of these compounds have active redox centers. Current–voltage measurements of the devices exhibited negative differential resistanc...
