In situ preparation of a Ti³⁺ self-doped TiO₂ film with enhanced activity as photoanode by N₂H₄ reduction.

Abstract: A new synthetic method to fabricate Ti3+-modified, highly stable TiO2 photoanodes for H2O oxidation is reported. With Ti foil as both the conducting substrate and the Ti3+/Ti4+ source, one-dimensional blue Ti3+/TiO2 crystals were grown by a one-step hydrothermal reaction. The concentration of Ti3+ was further tuned by N2H4 reduction, leading to a greater photoelectrocatalytic activity, as evidenced by a high photocurrent density of 0.64 mA cm−2 at 1.0 V vs RHE under simulated AM 1.5 G illumination. Electron paramagnetic resonance and Mott–Schottky plots reveal that higher charge-carrier density owing to N2H4 reduction contributes to the observed improvement. The generality of this synthesis method was demonstrated by its effectiveness in improving the performance of other types of photoanodes. By integrating the advantages of the 1D TiO2 architecture with those of Ti3+ self-doping, this work provides a versatile tool toward the fabrication of efficient TiO2 photoanodes.

Reducing port-related truck emissions: The terminal gate appointment system at the Ports of Los Angeles and Long Beach

Abstract: Growth in international trade and changing patterns of production have resulted in greatly increased volumes of freight traffic in urban areas Metropolitan areas serving as major nodes within the international trade network are particularly affected In California, state regulation was imposed on port operations in an effort to mitigate congestion and air pollution associated with increased port-related trade This paper presents an evaluation of the outcomes of California Assembly Bill (AB) 2650 at the Ports of Los Angeles and Long Beach The legislation permitted terminals to adopt either gate appointments or off-peak operating hours as a means of reducing truck queues at gates There is no evidence of reduced queuing or transaction times, and hence that AB 2650 did not result in reduced truck emissions
