TL;DR: In this paper , a comprehensive extinction risk assessment of reptiles is presented, which shows that at least 1,829 out of 10,196 species (21.1%) are threatened and represents 15.6 billion years of phylogenetic diversity.
Journal ArticleDOI
Combinatorial doping of TiO2 with platinum (Pt), chromium (Cr), vanadium (V), and nickel (Ni) to achieve enhanced photocatalytic activity with visible light irradiation
TL;DR: In this paper, the authors used a combination of several metal ions including platinum (Pt), chromium (Cr), vanadium (V), and nickel (Ni) to synthesize TiO_2 materials.
Journal ArticleDOI
Metal ion-sulfur(IV) chemistry. 2. Kinetic studies of the redox chemistry of copper(II)-sulfur(IV) complexes
TL;DR: Results are interpreted in terms of the initial formation of an inner-sphere complex, which is followed by a rate-limiting electron-transfer step, and are discussed in light of previously accepted mechanisms for the trace metal catalysis of the autoxidation of SO_3^(2-).
Journal ArticleDOI
Catalytic autoxidation of hydrogen sulfide in wastewater
TL;DR: In this paper, the catalytic effectiveness of cobalt (II)-4,4 4,4, 4',4',4'',4' 4'', 4''4' -tetrasulfophthalocyanine (Con^(II)TSP) for hydrogen sulfide autoxidation in wastewater was investigated.
Journal ArticleDOI
Chemical characterization of stratus cloudwater and its role as a vector for pollutant deposition in a Los Angeles pine forest
TL;DR: In this paper, high-concentrated, acidic stratus cloudwater was monitored as it intercepted a pine forest (Henninger Flats) 25 km northeast of Los Angeles.
