Snow on the Tibetan Plateau (TP) is an important signal for prediction of East Asian climate. In this study, relationship between TP spring snowmelt and summer precipitation in Northwest China (NWC) was investigated, along with possible mechanisms linked to impacts precipitation. The results showed that had significant NWC. For example, when there a large central- eastern TP, Hexi Corridor sout...

Abstract The Western Tibetan Vortex (WTV) is a large-scale circulation pattern identified from year-to-year variability, which was used to understand the causal mechanisms for slowdown of glacier melting over western Plateau (TP). A recent argument has suggested WTV set wind field anomalies resulting variability in near-surface air temperatures TP (above 1500 m), which, turn, likely driven by s...

A novel PMR polyimides (TMBZ-15) based on substituted benzidines is examined and compared to state-of-the-art PMR-15. The mechanism for the thermal decomposition of two specific PMR polyimides is obtained using TG/FTIR/MS techniques. In order to verify the pathway of polyimide degradation, a pyrolysis/GC-MS technique was employed to evaluate the organic degradation products, particularly the la...

Well-defined ferrocene-containing triblock copolymers were synthesized by atom transfer radical polymerization and self-assembled into highly ordered hexagonal arrays of cylinders via solvent annealing. The thin films were further used as a template and converted into highly ordered iron oxide nanoparticles (α-Fe2O3) by UV/ozonolysis and thermal pyrolysis.

Nitrogen-doped graphene materials with abundant pyridinic and quaternary nitrogen species were selectively synthesized by thermal surface polymerization of nitrogen-containing aromatic molecules. Catalytic studies revealed that the oxygen reduction by nitrogen-doped graphene, containing pyridinic and quaternary nitrogen species, proceeds via a four- and two-electron reduction pathway, respectiv...

This paper reports the synthesis of polypyrrole coated SnO2/ZnOelectrospunnanofibers via vapor phase polymerization method. In order to prepare one dimensional (SnO2- ZnO)/polypyrrole with the core sheath structure, first SnO2-ZnO composite nanofibers were synthesized via electrospinning method followed by adsorption of Fe 3+  on the surface of the SnO2-ZnO nanofibers and finally pyrrole w...

Poly(N-isopropylacrylamide) was labelled using a fluorogen with an aggregation-induced emission feature by direct polymerization; the label served as a fluorogenic probe that reveals fine details in the thermal transitions in the aqueous solution of the polymer; the working mode was readily tuned between non-monotonic and monotonic by changing the labelling degree of the polymer.
