A micro-oxygen-bomb calorimeter with a bomb of 4.8 cm3 internal volume was constructed in our laboratory. About 10 mg of sample was needed for each combustion experiment. The energy equivalent of this calorimeter was determined with electric energy. The standard diviation of mean from 5 measurements was 0.02 %.The enthalpies of combustion of pure C60 and C70 were determined, △cUm0(C60,cr)=-(25947.1±8.5)kJ•mol-1, △cUm0(C70,cr)=-(29956.1±8.9)kJ•mol. The enthalpies of formation of the two compounds were derived. Using the Laidler-type bond parameters for aromatic hydrocarbons, the estimated strain energies in C60 and C70 molecules were close each other and close to the estimated value from the model compound, corannulene.

 The etching resolution of electrochemical fabrication technique is influenced significantly by the diffusion layer of the etchant. It has been shown that a fast etching rate can achieve higher etching resolution due to so-called heterogeneous scavenging effect, while a lower etching rate will result in rather lower etching resolution. For the latter case, the confined etchant layer technique(CELT) has been employed to improve the etching resolution. i. e., a certain redox couple which can consume the etchant homogeneously and rapidly was added to the solution. The homogeneous scavenging effect confined the etchant within a narrow layer around the electrode surface and much improved etching resolution was achieved. Using the CELT and a needle-shaped microelectrode, an etching spot of several micro-meters was obtained at silicon wafer surface.

The heat properties of porcine brain tubulin polymerization and the interaction of the tubulin with taxol were studied with an MS-80 Calvet Microcalorimeter .The heat vibration occured within 1.5h when tubulin solution was diluted from a highe r concentration to a lower one. The thermodynamic parameters of tubulin polymerization at 303.15K and 298. 15K were measured in 10μmol•L-1 tubulin solution, its △H's were 22kJ•mol-1 and 29.3kJ•mol-1，respectively.Adding different concentration of taxol in the course of polymerization of tubulin give rise to a great change in △H. The time of taxol combining to polymerized microtubule was about one minute after the beginning of the reaction. The mechanism of tubulin polymerization under different conditions was discussed.

The colloid of pure copper was prepared from the solution of copper sulfate with hydrazine by controlling the condition of reductive reaction. The effect of the concentration of surfactant, sodium dodecyl on the size, shape and agglomeration was studied by using UV-Vis, spectrum. It's Shown that the surfactant can effectively prevent the agglomeration of particles and favor the formation of spherical particles smaller than 4nm when the concentration of surfactant is high enough.

Equilibrium adsorption of five substituted azobenzenes with pKa=1.5-5.0 from nonpolar organic solvents on 1:1 and 2:1 type layer silicates without layer charge (kaolinite, lizardite, pyrophyllite, and talc) was studied. It was shown that the shape of each adsorption isotherm belongs to L type, and, the color of the substituted azobenzene molecules adsorbed changed from basic type (yellowish) to acidic type (reddish or purplish). The higher the basicity (pKa) of the substituted azobenzene, the greater the adsorptive capacity. Moreover, the weak organic bases were more strongly adsorbed from n-hexane and carbon disulfide solutions than from benzene solution. From these facts, it was concluded that the adsorption mechanism of the weak organic bases on the minerals without layer charge is an acid-base interaction. It was also shown that the amount of acid sites of kaolinite saturated with Na, Ca, and Mg is almost identical, while that of montmorillonite shows strong dependence on exchangeable cation species. The decrease of the amount of acid sites due to the increase of RH also has quite different pattern for the minerals. These indicate that the origin of the acidity on kaolinite can not attributed to the hydrolysis of water molecules around exchangeable cations, as in the case of montmorillonite.

Intramolecular energy transfer and electron transfer of porphyrin-phthalocyanine heterodimers, linked by oxygen atom or piperazine in different solvents were investigated by fluorescence spectroscopy. The energy transfer and electron transfer efficiency were calculated. It has been found that energy transfer occurred in competition with electron transfer process depending on the polarity of the solvents. In polar solvents, electron transfer prevails while the energy transfer is favored in nonpolar solvents. The driving force(△GET0)of the electron transfer reaction in different solvents was estimated using Rehm-Weller equation. The results indicated that the conformations of the heterodimers as well as the ability of the solvent to stablize the charge-seperated state affect the photophysical process greatly. od correlations of φEnT and φET with solvent polarity f have been obtained.

The photoinduced electron transfer process of the TiO2 porous film in the electrolytes containing different redox couples was investigated using photoelectrochemical techniques. The photocurrent action spectra, the potential dependence of photocurrent and the photocurrent transients indicate that the TiO2 porous film shows characteristics of semiconductor of n-type with an optical gap of 3.26eV.
After adding Fe（CN）63-／4- quinhydrone (BQ/HQ) in the electrolyte, the photocurrent action spectrum is similar to that without redox couple and the photocurrent tail in the visible region is due to the injection of electron of excited state of p-benzoquinone to the conduction band of TiO2 porous film.
After adding Fe（CN）63-／4- in the electrolyte, the photocurrent action spectrum is obviously different from that without redox couple. In addition to the photocurrent peak in the region of wavelength less that 380nm, a wide peak is observed in the visible region of 400-600nm which increases the efficiency of light-electric conversion. The photocurrent is anodic at the potential more negative than 0.2V, becomes cathodic at the potential of -0.2~0.3V and is anodic again but weak at potential more positive than 0.3V. At the potential more positive than -0.2V, a cathodic spike is observed on the photocurrent transients plot at the moment of light-on, and later transforms into anodic steady state photocurrent, which can be interpreted that the rapid injection of the photoinduced electron of the charge-transfer complex of [Fe（CN）64-]TiO2 in the conduction band of TiO2 porous film, and then reduces Fe（CN）63- in the electrolyte. 

The reaction of CH4+O(3P)→CH3+OH was studied with the quasiclassical trajectory calculation. Both CH4(v=0, j=0) and CH4(v=1, j=1) were used. The results showed that the reaction of CH4(v=0, j=0) + O(3P) → CH3+OH is a direct reaction at lower or larger impact parameters with the preferentially backward scattered OH, and the product OH is rotationally cold and in the vibrationally ground state. The reaction of CH4(v=1, j=1) + O(3P)→CH3+ OH is a peripheral dynamical reaction with the preferentially forward scattered OH. This reaction was found to proceed with two distinct mechanism: for trajectories with a large impact parameter, a very short lived complex is formed with a rotationally cold OH, which is in vibrationally excited state(v=1) and scattered into the forward direction; at smaller impact parameters, the reaction proceeds via a direct mechanism with a rotationally hot OH, which has little vibrational excitation and is scatted backward.

The Chemisorption of Co on the Zn(Ⅱ) and Cu(Ⅰ) sites presenting on the Cu/ZnO(0001) surface has been studied with DFT method and HF method. While HF calculations underestimate the M-CO bonding, and give a wrong order of the M-CO(M=Zn(Ⅱ), Cu(Ⅰ)) bond strength, MP2 and DFT calculations give a rather realistic description for the chemisorption systems. Our theoretical prediction of IR spectroscopy of the Co/Cu/ZnO system is in od accordance with the experimental outcome.

 By the arc-discharge of carbon composite rods and graphite rods doped with other substances, fullerene mixture of containing about 10% of higher fullerenes was obtained. This provides the base for the separation, purification and further study of higher fullerenes. Moreover, it was found that the existence of perfect graphite structure in the anode rod is the necessary condition for the fullerene formation. Also, It was considered that other substance doped in the anode plays a role as the hot supports in the fullerenes' growing process, which is the reason of the high yield of higher fullerenes.

The influence of the fractal structure of Eu(DBM)3 non-crystalline solids on low frequency scattering was studied. It was found that vibrational excitations on the fractal are localized and can be described in terms of fractions. It was shown that reduced Raman scattering intensity is of a power law dependence of the vibrational frequencies for all samples. The fractal and spectral dimension were also determined, we found that our experimental value was in fair agreement with the theoretical one.

The 1H NMR spectra of CTAB, SDS and Triton x-100 aqueous micellar solutions containing dimethyl phthalate have been determined. The results indicate that dimethyl phthalate in CTAB, SDS and Triton x-100 micellar solutions at a low solubilizing concentration is adsorbed on the micelle-water interface. With the increase of solubilizing concentration, it is preferentially solubilised in both the palisade layer and hardly solubilised in the centre of the micellar core in CTAB micellar solution, and it is preferentially solubilised in both the palisade layer and the micellar core in SDS micellar solution while it is solubilised and uniformly distributed along the hydrocarbon chain of the surfactant in Triton X-100 micellar solution.

The solvation of the system of C60-toluene is studied by determining UV-Vis absorption spectrum, it is found that the maximum absorption wavelength of C60 exhibits red-shift in toluene medium. Viscosity measurement gives the thickness of the solvation layer as 0.85 nm. At temperature 30℃, the value of the diffusion coefficient is 3.12× 10-10m2•s-1 which is an order of magnitude less than that of small molecules. The results above indicate that C60 is solvated in toluene medium.

 Conducting Langmuir-Blodgett (LB) films based on a new asymmetrical tetrathiafulvalene (TTF) and its charge transfer complex with TCNQ were prepared by admixing with arachidic acid. The LB films were characterized by surface pressure-area isotherms, UV spectra, and X-ray diffraction. Conductivity of the LB films relating to the number of layers was studied. After doped with iodine the highest conductivity for the asymmetrical TTF and its TCNQ complex LB film reached 0.23 and 4.7×10-5 S•cm- 1 ，respectively.

 Cu-based H2S sorbents were studied by Temperature-Programmed Sulfiding(TPS) method. The effects of CuO contents, calcining temperature and supports on desulfurization performance were investigated. At low CuO content, CuO could be self assembled as monolayer on supports because of the interaction between CuO and support. With the increment of CuO content, CuO phase appeared. At higher calcinting temperature the interaction CuO with Al2O3 made the sulfiding temperature higher. The supports such as Al2O3, ZrO2, TiO2 and 13X zeolite play different roles in TPS process sulfiding temperature changed with various sopports.
