A co-block carbon nanofiber (CNF) is synthesized by using methylpropiolate and 2-pentyne. In order to achieve a patterned growth, the acetylenes are alternated, such that an A-B-A-B co-block CNF is produced. The distinct blocks are attributed to the type of acetylene used.关键词:carbon...
ZnO film,as a multi-use semiconductor material, has long attracted much attention.Since the discovery of UV luminescence of ZnO films in 1997,their preparation and the investigation of their photo-electronic properties have become a new hotspot.The strong self-compensation mechanism in ZnO makes it...
1. It consists of the thin superconducting film deposited on the magnetic insulator which creates spin splitting of the conduction electron subbands in the superconductor due to the effective exchange interaction heff. In addition there is a magnetic field B directed perpendicular to the film plane ...
The signal intensities were measured with a BAS 2000 (Fuji Photo Film, Tokyo). Table I. Kinetics of type I PIP5K isoenzymes The relative Vmax for PtdIns(4)P kinase were obtained after normalization of the Vmax values with protein amounts estimated by Western blotting. The normalizedVmax ...
;CONSTITUTION: This liquid crystal/high polymer composite film type display device is constituted by clamping the liquid crystal/high polymer composite films 6 between a pair of substrates. These liquid crystal/high polymer composite films 6 are formed within the plural block chambers segmented by ...
The effects of grinding (medium-coarse) and extraction time (14–22 h) on the physicochemical and sensorial properties of cold brew coffee produced using two types of Colombian specialty coffees (Huila and Nariño) were evaluated. Cold coffee brewed under coarse grinding and 22 h of extra...
The PHI film showed excellent transparency to UV light. The photosensitive polyimide containing 70 wt % PHI, 20 wt % BHMP, and 10 wt % DIAS showed a sensitivity of 70 mJ/cm2 and a contrast of 3.8 when it was exposed to 365 nm light and postbaked at 120 °C, followed by developing...
The realization of a quantum spin Hall (QSH) insulator working at high temperature is of both scientific and technical interest since it supports spin-polarized and dssipationless edge states. Based on first-principle calculations, we predicted that the two-dimensional (2D) binary compound of lea...
The fatty acids analysis was carried out in a gas chromatograph 6890 N (Agilent Technologies, Santa Clara, CA, USA) with a flame ionization detector (FID) and capillary column HP-88 122-88A7 of 100 m, 0.25 mm i.d, and 0.2 μm film thickness from Agilent Technologies. Helium was used...
