Characteristic speciation of airborne volatile organics in Kaohsiung, the largest industrial city in Taiwan, is present in this paper. Hourly concentration of airborne volatile organic compounds (VOCs) was monitored by on-line GC/FID and 3 hours-averaged sample was parallel conducted by canister during rush hour. Field sampling works were conducted at a traffic station (Qian-Jin) and an industr...

The focus of the present study is liquid-phase oxidation alkylaromatic hydrocarbons, particularly that ethylbenzene, in presence cobalt-based polymer complexes tuned to ethylbenzene and obtained based on cobalt salts a copolymer diethyl ether phenylphosphonic acid with acrylic acid. reaction was carried out without solvent at atmospheric pressure 900C temperature glass temperature-controlled eq...

The cytochromes P450 are versatile enzymes involved in various catalytic oxidation reactions, such as hydroxylation, epoxidation and dehydrogenation. In this work, we present combined experimental and theoretical studies on the change of regioselectivity in cyclohexadiene oxidation (i.e., epoxidation vs dehydrogenation) by oxoiron(IV) porphyrin complexes bearing different porphyrin ligands. Our...

Ammonia borane (AB) has high hydrogen density (19.6 wt%), and can, in principle, release up to 3 equivalents of H2 under mild catalytic conditions. A limited number of catalysts are capable of non-hydrolytic dehydrogenation of AB beyond 2 equivalents of H2 under mild conditions, but none of these is shown directly to derivatise borazine, the product formed after 2 equivalents of H2 are released...

background: the removal of ethylbenzene and xylene at a concentration of 10 mg/l from aqueous solutions by single- and multi-walled carbon nanotubes (swcnt and mwcnt, respectively) and hybrid carbon nanotubes (hcnt) was evaluated at a nanomaterials dose of 1 g/l, a contact time of 10 minutes, and a ph 7. methods: synthetic samples were analyzed by gas chromatography/mass spectrometry (gc/ms). i...
