Morphology and electrochemical properties of a gel blend polymer electrolyte based on PVDF-HFP/PEO blend
No full textHypothesis: In recent years, gel polymer electrolytes (quasi-solid state electrolytes) have attracted great attention as a suitable substitute for liquid electrolytes. On the other hand, ionic liquids could dramatically enhance the ionic conductivity of electrolytes. In this work, gel polymer electrolytes based on poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)/poly(ethylene oxide) (PEO) blends (for application in dye-sensitized solar cells (DSSCs)) and imidazoliumbased ionic liquids were prepared. It is supposed that blending these two polymers could reduce the degree of crystallization and increase the porosity of the electrolyte blend to yield a higher electrolyte uptake and ionic conductivity. Methods: Polymer blend electrolytes were prepared in different blend ratios and in the presence of either one of the ionic liquids including BMII or BMIMBF4 through phase inversion method and their properties were investigated by differential scanning calorimetry (DSC), mercury porosimetry, electrolyte uptake, and morphology to optimize the blend ratio. Findings: It was found that the blend ratio of 60/40 (w/w) PVDF-HFP/PEO has the highest porosity and electrolyte uptake. Crystallization investigations by DSC showed that there is a direct relationship between the decrease of crystallinity of two polymers and the increment of electrolyte ionic conductivity. Electrolyte uptake gradually increased with increasing PEO component concentration up to 40 wt%, and reached a maximum of 98.49% and 89.48% for BMIMBF4 and BMII, respectively. Beyond this concentration, a decrease in electrolyte uptake was seen, which is an undesirable feature for the produced samples. In this blend ratio ionic conductivity was measured as 2.07 mS/cm and 1.78 mS/cm for PVDF-HFP/PEO/BMIMBF4 and PVDF-HFP/ PEO/BMII electrolytes, respectively

Muhyiddin Abdul Qodir Al-Manafi ini sebagian besar jamaah memperhatikan dengan baik materi yang disampaikan K.H. M. Muhyiddin Abdul Qodir Al-Manafi. Selain itu jamaah menyatakan senang dengan diadakannya pengajian rutin. Pengertian jamaah terhadap pengajian ini, sebagian besar jamaah dapat mengert dan memahami materi yang disampaikan oleh K.H. M. Muhyiddin Abdul Qodir Al-Manafi. Penerimaan jamaah terhadap pengajian ini, menunjukan bahwa lebih dari setengahnya jamaah dapat menerima materi pengajian dengan baik. Menurut responden materi yang disampaikan sesuai dengan apa yang dibutuhkan oleh responden sehingga menimbulkan dampak yang sangat positif untuk lebih rajin beribadah, dan mengamalkannya dalam kehidupan sehari-hari.Peningkatan ibadah mahdoh jamaah sebagian besar mengalami peningkatan. Dari hasil angket, harga koefesien korelasi hasil perhitungan adalah 0,69 ini berarti menunjukan bahwa koefesien tersebut termasuk kategori korelasi sedang, karena terletak pada interval anatara 0,41-0,70.
ternyata antara variabel X (pengajian KH M Muyyddin) dan variabel Y peningkatan ibadah mahdoh terdapat pengaruh sebesar 28% dipengaruhi oleh adanya pengajian rutin KH M Muhyiddin, sementara 72% dipengaruhi oleh faktor lain
Thermal expansion anomalies of R(Fe, M)(12) (R=Y, Nd; M=Mo and Si)
No full textStructural and thermal-expansion anomaly studies on R(Fe,M)(12) (R=Nd and and Y, M=Mo and Si) compounds were performed by x-ray diffraction. Mo atoms occupy the 8i site. While Si atoms occupy the 8f and 8j sites but not the 8i site. Thermal-expansion anomaly shows only in ab plane in the Mo compounds, while becomes very weak and along with only the c axis in the Si compounds. The anomaly was attributed to the contribution of the interactions of short Fe-Fe distances similar to the previous explanation on other R-Fe intermetallics and that of other strongly positive interactions such as 8j-8j.

A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
