We report a high-resolution gas-phase UPS spectrum of zinc phthalocyanine (ZnPc) together with a detailed analysis of the vibronic structure of the first ionization band, showing that presents the lowest value of the intramolecular reorganization energy experimentally reported for a molecular organic semiconductor.

Zinc oxide nanorods (ZnO-NR) were prepared on Zn plates with a ratchet structure by hydrothermal processing. Then the Leidenfrost phenomenon of sample was evaluated after coating fluoroalkyl silane. After formation ZnO-NR, temperature decreased approximately 20 °C. The terminal velocity self-propelled droplets depended temperature. dominant mechanism for self-propulsion water without ZnO-NR at ...

Local structures around metal atoms in Hi and Zn substituted 132-hydroxy-bacteriochlorophyll a (Ni-HOB, and Zn-HOB) with and without insertion into the accessory bacteriochlorophyll a (BChla) sites in Rhodobacter sphaeroides photosynthetic reaction centers (RC) are studied using X-ray absorption spectroscopy. The penta-coordination of Ni-HOB and Zn-HOB in the RC is similar to that of BChl a in ...

The crystal structure of a putative dipeptidase (Phdpd) from Pyrococcus horikoshii OT3 was solved using X-ray data at 2.4 A resolution. The protein is folded into two distinct entities. The N-terminal domain consists of the general topology of the alpha/beta fold, and the C-terminal domain consists of five long mixed strands, four helices, and two 3(10) helices. The structure of Phdpd is quite ...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

Methods: To test the possible cytotoxic...

We examined the influence of zinc status on expression of certain transcription factors involved in regulation of apolipoprotein A-I (apoAI) expression in human hepatoblastoma Hep G2 cells. A low zinc basal medium (zinc deficient, ZD) consisting of DMEM and 10% Chelex100-treated fetal bovine serum was used to deplete cellular zinc over one passage. Cells were also cultured for one passage in me...
