Studies of Crystalline Aggregates of Pheophorbide and Bacteriopheophorbide by Electro-Absorption (Stark Effect) Spectroscopy and Powder X-ray Diffraction
GYROTRON 2ND HARMONIC SUBMILLIMETER WAVE
2016/5/23
Absorption and electro-absorption (Stark effect) spectra of polycrystalline and lyophillized samples of pheophorbides and bacteriopheophorbides have been measured in order to obtain information on the...
X-ray Diffraction Study of the Changes Induced During the Thermal Degradation of Poly (Methyl Methacrylate) and Poly (Methacryloyl Chloride)
X-raythe Changes Induced During Thermal Degradation Poly
2010/4/20
Poly (methyl methacrylate) -- PMMA -- and poly (methacryloyl chloride) -- PMACl -- were synthesized by free radical solution polymerization. The thermal stabilities of these polymers were determined w...
X-Ray Diffraction Study of Heat-Treated Graphitized and Ungraphitized Carbon
Graphitized and ungraphitized carbons Heat treatment XRD
2010/6/28
Heat treatment of graphitized and ungraphitized carbon samples was carried out in air and argon atmosphere from ambient temperature to 700\circC. The changes in degree of amorphousness, mean crystalli...
Time-resolved X-ray diffraction patterns can be inverted to obtain photoinduced dynamics without resorting to additional and often unknown information (e.g., potential energy surfaces), as required in...
