Pressure effects on fluorescence and photodimerization of anthracene and 9-methylanthracene in solution

The relative values of photodimerization yields Φ. and fluorescence yields Φ_f with anthracene and 9-methylanthracene were measured in n-hexane at room temperature under pressures up to 3, 000kg/cm^2. In anthracene where Φ_f has a slight pressure dependence, the apparent first order rate constant k_o_b_s for photodimerization yield was approximately inversely proportinal to the viscosity of the solvent. On the other hand, in 9-methylanthrareae where Φ_f increases steeply with increasing pressure, k_o_b_s did not decrease with pressure so much as predicted from the increase of the viscosity of the solvent. Considering the changes of Φ_f as the changes of lifetime. τ_f of the lowest excited singlet state S_1, the pressure dependences of photodimerization rate constants k_r were obtained according to the relation k_o_b_s = k_r.τ_f. In 9-methylanthracene as well as anthracene k_r were nearly inversely proportional to the viscosity of the solvent. The remarkable effects of pressure on fluorescence yields also were discussed in view of the intersystem crossing from the S_1 state to the second triplet state T_2

Micrometer-scale Imprinting Process for Ceramic Sheet from Powder Compound Material

AbstractA micro patterning process for thin ceramic sheets is proposed and developed in this paper. Thin sheets with a micro pattern have been expected to improve performance of solid oxide fuel cell. The authors focused on imprinting and powder metallurgy processes, and have developed the combined process, which has been named micro powder imprinting process. In this process, ceramic powder and polymer binder materials are mixed with pure water by milling machine. After drying out the water from the slurry, a thin compound sheet was obtained. Subsequently, the sheet was pressed using a fine patterned mold with heating to transcribe a micro pattern on the sheet. Finally, the imprinted sheet was heated for removing the polymer binder and for sintering. As further improvement of the process, a compound sheet was stacked on a pure polymer sheet during the imprint process to transcribe a micro pattern on the both sides of the sintered sample. The technique is useful for improved solid oxide fuel cell

Caveolae-Specific CaMKII Signaling in the Regulation of Voltage-Dependent Calcium Channel and Cardiac Hypertrophy

Cardiac hypertrophy is a major risk for the progression of heart failure; however, the underlying molecular mechanisms contributing to this process remain elusive. The caveolae microdomain plays pivotal roles in various cellular processes such as lipid homeostasis, signal transduction, and endocytosis, and also serves as a signaling platform. Although the caveolae microdomain has been postulated to have a major contribution to the development of cardiac pathologies, including cardiac hypertrophy, recent evidence has placed this role into question. Lack of direct evidence and appropriate methods for determining activation of caveolae-specific signaling has thus far limited the ability to obtain a definite answer to the question. In this review, we focus on the potential physiological and pathological roles of the multifunctional kinase Ca2+/calmodulin-dependent kinase II and voltage-dependent L-type calcium channel in the caveolae, toward gaining a better understanding of the contribution of caveolae-based signaling in cardiac hypertrophy
