Photo-degradation of organic pollutants plays an important role in their removal from the environment.
Fire suppression with water mist is widely considered to be an alternative gaseous fire agents. Much commercial activity has occurred in the last 5 years develop technology for systems based on mist. Although researchers 1950's recognized dominant mechanisms of extinguishment, recent experimental work improved understanding extinguishing properties This paper proposes a classification terminology mists facilitate discussion systems. It describes primary namely heat extraction, oxygen...
This study presents a detailed mechanistic and kinetic investigation that explains the experimentally observed high yields of formation polybrominated dibenzo-p-dioxins dibenzofurans (PBDD/Fs) from diphenyl ethers (PBDEs), commonly deployed in brominated flame retardants (BFRs). Theoretical calculations involved accurate meta hybrid functional M05-2X. The previously suggested pathways debromination generation bromophenols/bromophenoxys/bromobenzenes were found to be unimportant corridors for...
Guided by recent experimental measurements, this study theoretically investigates the initial steps operating in interactions of ceria surface CeO<sub>2</sub>(111) with three CVOC model compounds, namely chloroethene (CE), chloroethane (CA) and chlorobenzene (CB).
This contribution presents pathways for the formation of three nitrogenated dioxin-like species, carbazole, phenoxazine, and phenazine via unimolecular rearrangements diphenylamine (DPA) its nitro substituents (NDPA). The latter represent major structural entities appearing in formulations explosives propellants. Intramolecular H transfer from amine group to one two O atoms denotes most accessible route decomposition NDPA. Further afford carbazole. A loss an ortho substituent DPA, followed...
This study presents a detailed investigation into the gas-phase thermal decomposition of tetrabromobisphenol A (TBBA), that is, most widely used brominated flame retardant (BFR). Elimination one methyl groups characterizes sole dominant channel in self-decomposition TBBA molecule at all temperatures. high-pressure rate constant for this reaction is fitted to k(T) = 2.09 × 10(10)T(1.93) exp(-37000/T) s(-1). The high factor and low activation energy arise from formation delocalized radical...
Catalysts of iron oxide on γ-alumina and silica which were prepared by an incipient wetness impregnation technique have been investigated in effort to understand how the surface chemical properties are influenced nature supports. Surprisingly, this is first study compare depth influence supports physicochemical parameters such as acidity, site nuclearity, reducibility. In study, characterisation techniques including N2 physisorption at -196 °C, ammonia temperature-programmed desorption,...
The International Association of Fire Safety Science (IAFSS) is comprised members from some 40 countries. This paper presents the Association's thinking, developed by Management Committee, concerning pressing research needs for coming 10 years presented as IAFSS Agenda 2030 a Safe World. are couched in terms two broad Societal Grand Challenges: (1) climate change, resiliency and sustainability (2) population growth, urbanization globalization. Challenges include significant fire safety...
Oxidation of a bituminous coal has been studied using an isothermal flow reactor operated at temperatures between 60 and 90 °C, packed with particles smaller than 853 μm in diameter. The time-dependent rates production CO2 CO during experiments were obtained simultaneously from the measurement concentration reactor's exit, just after onset oxidation coal, dual-column micro gas chromatograph. ratio was high beginning experiment, but decreased to reach steady state 10 hours or so. Experimental...
We present an ab initio procedure for accurately calculating aqueous-phase pKa values and apply it to study the acidity of nitrous acid (HNO2, or HONO). The was obtained from calculated gas-phase acidities solvation free energies via a thermodynamic cycle model chemistry Barone et al. (J. Chem. Phys. 1997, 107, 3210). Solvation were at HF/6-31G(d) level using dielectric-polarizable continuum integral equation formalism-polarizable solvent models (D-PCM IEF-PCM, respectively), with D-PCM...
Density functional theory (DFT) calculations have been used to obtain thermochemical parameters for formation of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDF) from the oxidation 2-chlorophenol. Formation mechanisms PCDD through radical-radical coupling investigated in detail. The sequence 2-chlorophenoxy radical has studied. chlorinated bis keto dimers which results cross at ortho carbon bearing hydrogen (a known direct route PCDF formation) passes a tight transition...
