Formation and UV-laser induced desorption of Cl-containing species on/from GaAs(100) surface

引用

Progress in Natural Science:Materials International 1996年第1期 77-85页

作者：宋真,吕日昌,Satoshi Shogen,Masahiro kawasaki,ikuo Suemune State Key Laboratory of Molecular Reaction Dynamics Dalian Institute of Chemical Physics Chinese Academy of Sciences Dalian 116023 China State Key Laboratory of Molecular Reaction Dynamics Dalian Institute of Chemical Physics Chinese Academy of Sciences Dalian 116023 China Research Institute for Electonic Science Hokkaido University Sapporo 060 Japan Research Institute for Electonic Science Hokkaido University Sapporo 060 Japan Research Institute for Electonic Science Hokkaido University Sapporo 060 Japan

XPS was used to analyse the GaAs(100) substrate before and after concentrated HO treatment. The untreated RTO GaAs(100) surface has a 0.17nm thick oxide overlayer on it. HC1 treatment canremove this oxide layer and form a layer of Cl-contaimng species——GaClx. The 355 nm and 193 nm laserwas tried to study the 'laser induced desorption of GaCl,. XPS was also used to monitor the change of Cl quantity by laser irradiation. The results show that the 355 nm laser induces a thermal desorption of GaClx. By the behavior of the thermal desorption, we conclude that the GaClx on the HC1 treated GaAs(100) surface may be GaCl. The 193 nm laser can dissociate GaCl and induce a photo dissociation desorption of Cl.

Preparation and Evaluation of Poly-γ-Glutamic Acid Hydrogel Mixtures with Basic Drugs or Acidic Drugs: Effect on Ease of Swallowing and Taste Masking

引用

Pharmacology & Pharmacy 2019年第10期10卷 427-444页

作者： Honami Kojima Saeri Ikegami Shiho Nakamura Haruka Nishikawa Tamami Haraguchi Miyako Yoshida Minoru Ozeki ikuo kawasaki Takahiro Uchida Faculty of Pharmaceutical Sciences Mukogawa Women’s University Nishinomiya Japan

The purpose of this study was to prepare a poly-γ-glutamic acid hydrogel (PGA gel), to examine its ease of swallowing using texture profile analysis (TPA) and to evaluate its taste-masking effects on basic or acidic drugs using the artificial taste sensor. Using TPA, 0.5% and 1.0% PGA gels, 0.5% and 1.0% agar and 1.0% ι-carrageenan in the absence of drug was examined the hardness, adhesiveness and cohesiveness, ranked according to permission criteria published by the Japanese Consumers Affairs Agency. 0.5% PGA gel and 1.0% agar were classified into grade II. In the taste sensor measurement, the bitterness suppressions by 0.5% PGA gel were larger than that by 1.0% agar in all drugs and the bitterness suppressions of basic drugs in 0.5% PGA gel were more potent than those of acidic drugs in 0.5% PGA gel. 1H-nuclear magnetic resonance spectroscopic analysis was carried out to examine the difference in mechanism of bitterness suppression between basic drugs and acidic drugs mixed with PGA gel. The signals of the proton nearest to the nitrogen atom of basic drugs shifted clearly upfield, suggesting an interaction between the amino group of basic drugs and the carboxyl group of PGA gel. In conclusion, PGA gel is expected to be a useful excipient in formulations contained various drugs, especially basic drugs;it also has advantage for not only increasing ease of swallowing but also masking the bitterness of drugs even though a small amount of a single drug dose might be preferred.
