A transparent superhydrophobic TiO2 film, prepared by spin-coating a TiO2 slurry on a glass substrate and modifying the resultant TiO2 film with fluoroalkylsilane molecules, was patterned by illumination with ultraviolet light through a photomask, producing a superhydrophobic/superhydrophilic surface micropattern with very small superhydrophilic areas, which we were able to selectively fill with alginate hydrogel. 相似文献

Indium Tribromide Catalyzed Coupling Reaction of Enol Ethers with Silyl Ketene Imines toward the Synthesis of β,γ‐Unsaturated Nitriles 下载免费PDF全文
Dr. Yoshihiro Nishimoto Takashi Nishimura Prof. Dr. Makoto Yasuda 《Chemistry (Weinheim an der Bergstrasse, Germany)》2015,21(50):18301-18308
Herein, a coupling reaction of enol ethers with silyl ketene imines in the presence of catalytic amounts of InBr3 and Me3SiBr is described. Kinetic studies have revealed that an indium catalyst and Me3SiBr accelerated the coupling process and the regeneration of the catalyst, respectively. Various types of enol ethers and silyl ketene imines are applicable. In addition, a formal synthesis of verapamil was achieved by using this novel coupling reaction. 相似文献

Interaction mode of an inhalation anesthetic halothane with water-soluble globular proteins, myoglobin (Mgb) and lysozyme (Lys), was studied by differential scanning calorimetry (DSC) and viscometry, and the results were compared with those of bovine serum albumin (BSA). The anesthetic sensitivity was markedly different among the proteins: Mgb was destabilized, Lys was slightly destabilized, and BSA was conversely stabilized. Further, the interaction mode was quite different from those of specific binders for the proteins. The anesthetic sensitivity was highly correlated with the hydrophilicity on the protein surface (Mgb?<?Lys?<?BSA) and the rigidity of the protein structure (BSA????Mgb?<?Lys). We showed that the anesthetic sensitivity among globular proteins can be roughly classified into four categories, and proteins with small hydrophilicity and soft structure are suitable as model proteins of anesthesia. By contrast, the binding of the specific binders was characterized by the lower effective concentrations. The molar ratio of the binder to the protein at the effective concentration was well consistent with the binding number determined from the X-ray structural analysis. Moreover, the interaction mode of the binder was not necessarily in accord with the mode expected from the change in the protein structure. Considering the above facts, we can systematically interpret the effect of an anesthetic on globular proteins by four factors: (1) hydrophobicity of an anesthetic, (2) hydrophilicity of a protein surface, (3) rigidity of a protein structure, and (4) molar ratio of an anesthetic to a protein at the effective concentration. 相似文献

The bilayer packing states of a series of diacylphosphatidylcholines (CnPC) containing linear saturated acyl chains were examined by a high-pressure fluorescence method. We revealed from the second derivatives of Prodan fluorescence spectra for all bilayer membranes that the Prodan molecules can be distributed into multiple sites in these bilayer membranes and move around the head-group region, depending on the phase state. The hydrophobicity of the PC molecules markedly affected the distribution quantities of the Prodan molecules between the gel and liquid crystalline phases. The distribution of the Prodan molecules into the gel phase decreased with the increasing acyl chain length while that into the liquid crystalline phase conversely increased. The present study suggests that Prodan can sensitively recognize the packing states and strengths in the bilayer membranes and becomes a good packing indicator. 相似文献

Background
The hematopoietic Granulocyte-Colony Stimulating Factor (G-CSF) plays a crucial role in controlling the number of neutrophil progenitor cells. Its function is mediated via the G-CSF receptor, which was recently found to be expressed also in the central nervous system. In addition, G-CSF provided neuroprotection in models of neuronal cell death. Here we used the retinal ganglion cell (RGC) axotomy model to compare effects of local and systemic application of neuroprotective molecules. 相似文献117.

A deuterated n=1 Ruddlesden-Popper compound, DLnTiO4 (HLnTiO4, Ln=La, Nd and Y), was prepared by an ion-exchange reaction of Na+ ions in NaLnTiO4 with D+ ions, and its structure was analyzed by Rietveld method using powder neutron diffraction data. The structure analyses showed that DLaTiO4 and DNdTiO4 crystallized in the space group P4/nmm with a=3.7232(1) and c=12.3088(1) Å, and a=3.7039(1) and c=12.0883(1) Å, respectively. On the other hand, DYTiO4 crystallized in the space group P21/c with a=11.460(1), b=5.2920(4), c=5.3628(5) Å and β=90.441(9)°. The loaded protons were found to statistically occupy the sites around an apical oxygen of TiO6 octahedron in the interlayer of these compounds, rather than Na atom sites in NaLnTiO4. 相似文献

Cumulative waveform distortion in cascaded optical amplifierrepeaters for multigigabit IM/DD systems
Tomofuji H. Nishimoto H. Horimatsu T. Minami T. Touge T. 《Photonics Technology Letters, IEEE》1990,2(10):756-758
An analysis was conducted of a cumulative pattern-dependent waveform distortion in cascaded semiconductor laser and Er3+-doped fiber amplifiers. At 2.5 Gb/s, cumulative waveform distortion limits the number of cascaded amplifiers to about 20 for the semiconductor amplifiers. The Er3+-doped fiber amplifier is relatively unaffected-over 100 stages can be cascaded. The Er3+ amplifier is seen to be the better choice for long-haul multigigabit systems 相似文献
