[Spatiotemporal Dynamics of CO Emissions in Chongqing: An Empirical Analysis at the County Level].

China's CO emissions present obvious temporal and spatial distribution characteristics. Therefore, the study of spatiotemporal dynamics of CO emissions could provide useful information for the government and policy-makers on viable CO emissions mitigation in China. Using Chongqing as a case study, we investigated the spatiotemporal dynamics of CO emissions at the county level (38 counties) from 1997 to 2012.

Possible regulation of genes associated with intracellular signaling cascade in rat liver regeneration.

Objective: The importance of signal transduction in cell activities has been generally accepted. The purpose of this study was to analyze the regulatory effect of intracellular signaling cascade-associated genes on rat liver regeneration (LR) at transcriptional level.

Material And Methods: The associated genes were originally obtained through a search of the databases and related scientific publications; their expression profiles were then checked in rat LR using the Rat Genome 230 2.

[Study on electro-degradation of new conjugated polymer PFO-BT15 light emitting diodes].

In the present paper electroluminescence spectrum and Raman spectrum were used to study electro-degradation of polymer light emitting devices (PLEDs) of PFO-BT15, a new and high-efficiency emitting polymer synthesized by the institute of polymer optoelectronic material & devices (IPOM) in South China University of Technology. The PLEDs with a configuration of ITO glass/PEDOT(120 nm)/PFO-BT15(80 nm)/Ba(4 nm)/Al(200 nm) emitted green light at 550 nm when 5 V dc voltage was applied. Three of those devices were used to study the electro-degradation mechanism of PLEDs.
