A simple method of liquid phase direct precipitation (LPDP) is employed to prepare oxotitanium phthalocyanine (TiOPc) nanoparticles. By encapsulation within casein coating, the TiOPc nanoparticles exhibit uniform and well controlled particle sizes. The results of photoinduced discharge experiment demonstrates that the photoconductivity of the photoreceptors fabricated with TiOPc nanoparticles and fluoronone based azo pigments as composite carrier generation materials was substantially enhanced. The photosensitivity has been improved three times as the TiOPc particle size decreased from 100 nm to 40 nm.

A versatile analytical method(VAM) for calculating the harmonic components of the magnetomotive force(MMF) generated by diverse armature windings in AC machines has been proposed, and the versatility of this method has been established in early literature. However, its practical applications and significance in advancing the analysis of AC machines need further elaboration. This paper aims to complement VAM by augmenting its theory, offering additional insights into its conclusions, as well as demonstrating its utility in assessing armature windings and its application of calculating torque for permanent magnet synchronous machines(PMSM). This work contributes to advancing the analysis of AC machines and underscores the potential for improved design and performance optimization.

A series of amphiphilic thermosensitive poly- phosphazenes (PNIPAm-g-PPP) bearing N-isopropylacryla- mide oligomers (oligo-PNIPAm) and glycine ethyl groups (GlyEt) as co-substituents have been synthesized via polymer substitute reaction. UV-visible spectra indicated that the aqueous solution of PNIPAm-g-PPP exhibited the lower critical solution temperature (LCST). Furthermore, the LCST was seriously influenced by the substitution ratios of PNIPAm to GlyEt in the copolymer. The more GlyEt the copolymer contained, the lower LCST it had. The critical association concentration (cac) of copolymers was deter- mined by fluorescence probe method. It was found that cac was decreased with increasing GlyEt content of polyphos- phazene. Also the formation of self-assembled micelles or nano-particles was confirmed by TEM.

关键词： polyphosphazene thermosensitivity lower critical solu- tion temperature micelle.
