Bibliography: leaves 124-131.<br>Photochemical smog is the name given to a complex sequence of chemical reactions that occurs in the presence of sunlight. These reactions comprise a mix of organic and inorganic compounds, including a number of toxic secondary pollutants such as ozone (O3) and peroxyacetyl nitrate. These substances are commonly referred to as oxidants and are the result of numerous reactions of primary pollutants or precursors (including nitrogen oxides (NOx) and non- methane hydrocarbons (NHHC)) emitted from vehicle exhausts and to some extent industry, O3 is the major constit

Abstract:

The rapid rising anthropogenic emissions driven by economic growth over China documented by satellite observations and bottom-up inventories have led to severely degraded air quality, and also have been suggested to be linked to the recent upward trends of tropospheric O₃ over the regions downwind of China. Multi-scale modeling analyses facilitated by ground-level, aircraft and satellite observations have been conducted to understand the atmospheric chemistry over China. Analyses using a 1-D photochemical model constrained by measurements at Beijing in August of 2007 suggest that reactive arom

Abstract:

This work investigates the computer modelling of the photochemical formation of smog products such as ozone and aerosol, in a system containing toluene, NOx and water vapour. In particular, the problem of modelling this process in the Commonwealth Scientific and Industrial Research Organization (CSIRO) smog chambers, which utilize outdoor exposure, is addressed. The primary requirement for such modelling is a knowledge of the photolytic rate coefficients. Photolytic rate coefficients of species other than N02 are often related to JNo2 (rate coefficient for the photolysis ofN02) by a simple f

Abstract:

In urban environments, a significant portion of atmospheric aerosols are of organic composition with the secondary organic aerosol (SOA) fraction being one of the most important but least understood. This work examines SOA production in a smog chamber using a-pinene and isoprene as biogenic precursors and particle-free ambient urban air as anthropogenic emissions. The observations revealed that the SOA formation is controlled by the components present in the matrix and a-pinene or isoprene affect the reaction processes in such a way that the SOA concentration is either increased or decreased.

However, LCD still needs improvement, such as power consumption, contrast, motion blur, etc. To achieve better image quality and energy saving, nanoparticles were added into the liquid crystal, reducing the elastic constants and increasing the dielectric constants to shorten the response time and lower the threshold voltage. In this research, firstly, we used polyvinylpyrrolidone (PVP) and 4-cyano-4''-pen

Abstract:

abstract: Banded iron formations (BIFs) are among the earliest possible indicators for oxidation of the Archean biosphere. However, the origin of BIFs remains debated. Proposed formation mechanisms include oxidation of Fe(II) by O2 (Cloud, 1973), photoferrotrophy (Konhauser et al., 2002), and abiotic UV photooxidation (Braterman et al., 1983; Konhauser et al., 2007). Resolving this debate could help determine whether BIFs are really indicators of O2, biological activity, or neither. To examine the viability of abiotic UV photooxidation of Fe, laboratory experiments were conducted in which Fe-

Abstract:

碩士<br>國立成功大學<br>環境工程學系<br>105<br>Abstract Silver nanoparticles (AgNPs) are a commonly used nanoparticle and have useful characteristics such as excellent antibacterial property. A recent survey indicates that AgNPs are one of the most frequently used (24%) nanomaterials in the consumer products available on the markets across 32 countries. AgNPs once released into the environment could be oxidized to form silver ions which could be bound to dissolved organic matter (DOM). It has been shown that silver ions can be photoreduced to form AgNPs by natural organic matter (NOM) under sunlight condit
