The results reveal that two energy transfer paths (i. e.β-PEB→α/β-PCB and β-PEB→α/βPCB′) with time constants of 50ps and 200ps, respectively, exist in R-PC monomers, and that α/β-PCB′chromophores are the terminal emitting acceptors with fluorescence lifetimes of 1150 ps. The experimental results of time-resolved fluorescence spectroscopy in case of R-PC trimers exhibit that the corresponding energy transfer processes are faster in R-PC trimers than in R-PC monomers, with time constants being 45ps, 165 ps and 920ps.

For the case of pH-induced micellization, as pH of the solutions decreases to below 4.6, micellar structure having insoluble complexes of PAA/PNiPAAm as the core and solvated HEC chains as the shell can be obtained due to hydrogen-bonding complexation between the proton-acceptors in PNiPAAm and the proton-donors in PAA.

首先发现pH诱导胶束形成的临界pH值在4.6附近，证实了胶束化机理是由于低pH下PAA接枝链上的质子给体与PNiPAAm支链上的质子受体间的氢键络合形成胶束的&核&，HEC不参与络合形成胶束的&壳&。

The paper involved two parts: Part 1: A two-chambered microbial fuel cell was constructed with high-concentration sodium acetate as fuel in the anode. The influence of different electron acceptors in the cathode, external resistance value, pH value and concentration of sodium acetate on electricity generation in MFC was investigated. The result showed that the maximum power density of 294.72 mW/m2 and the coulombic efficiency of 25.87% was achieved at sodium acetate concentration of 6.46 g/L, pH 7.0, external resistance 500Ωin the anode and when using potassium permanganate as electron acceptor in the cathode.
