Recently, the adsorption behavior of protein on solid substrate has attracted much attention for the reason that adsorption on a substrate is the first key step for other further electrochemical investigation1. Meanwhile the free adsorption could provide a relative well-ordered structure, with which some fundamental study could be carried out conveniently2. As we know, the electrochemical impedance spectroscopy (EIS) method has become one of the powerful techniques to detect the change of i… 相似文献

Today, batteries with high capacity, good cyclability, long life and environmental goodness are much required to meet some pressing demands of our modern society. In principle, lithium ion cells can satisfy these requirements1. But the properties of the cathode materials have limited the further development of the lithium ion cells. The studied cathode materials before were mainly LiCoO2, LiMn2O4, LiNiO2. The LiCoO2 has disadvantages including cost and environmental risk although it is… 相似文献

The interaction between ethyl orange (Eto, guest) and β-cyclodextrin dimers (1a~d, host) bridged with 2-t-butoxycarbonyl(Boc)-amino diacid was investigated. A remarkable synergic complexation of two cavities in host molecule was observed. 相似文献

The chemistry of samarium (II) iodide (SmI2) is of current interest in organic synthesis. SmI2 has been developed as a powerful, versatile and ether-soluble single-electron reductant and many examples have been reported of its use in the reduction of various functional groups1. Though SmI2 is a useful reagent, storage is difficult because it is very sensitive to air oxidation. On the other hand, metallic samarium is stable in air and has strong reducing power (Sm3+/Sm=-2.41 V). These pr… 相似文献

Helicia nilagirica Beed. belongs to the plant of Proteaceae family. The seeds of the plant is for treatment of insomnia and neurasthenia in Jingpo nationality in Yunnan Province1. Helicid and helicidol were isolated from the seeds of the plant2,3, and the helicid was recorded in the Yunnan Pharmacopoea at the 1987 edition. The chemical constituents of the leaves of this plant has not been reported yet in the literature. This paper is concerning the study of the chemical component of the… 相似文献

1. INTRODUCTION The partial oxidation of alkenes (forming acids, aldehydes and alcohols) is of considerable interest to the chemical industry. In most cases, more than one oxygenated product is formed from a given starting material and all products are susceptible to complete oxidation to carbon dioxide and water [1]. As mimetic oxygen carrier or oxidation catalyst, metalloporphyrins have been widly studied [2~7]. Among the non-porphyrin systems, the manganese complexes of Schiff base are… 相似文献

Cucurbit[n]urils (CB [n]),macropolycyclic compounds self-assembled from an acid-catalyzed condensation of glycoluril and formaldehyde1, can form inclusion complexes with a number of organic substrates in water2. Usually, CB [6] is used in the studies because of its easy synthesis, and the driving forces for its binding are considered to be the hydrophobic effect and dipole-dipole interactions. CB[n] 1Very recently, Kim et al reported the synthesis of CB [5], CB [7], and CB [8]3. They fou… 相似文献
