Abstract:
The freezing kinetics of binary nitric acid/water aerosols is of fundamental importance to the modelling of polar stratospheric clouds and the role they in ozone depletion over the Arctic/Antarctic regions. Cirrus clouds are also often composed of nitric acid solutions, hence an understanding of freezing process in these aerosols also aids in modelling the earth's radiation budget and global warming. This thesis explores the kinetic phase diagram of nitric acid/water aerosols with sizes ranging between 0. 2 and 1. 5 mm in radius and concentrations ranging between pure water and 0. 45

A solid powder was obtained which was calcinated at 700℃ 1hr to get Ni-Cu-Zn ferrite powder. From the XRD patterns, the crystalline structure of Ni-Cu-Zn ferrite powder was only spinel cubic structure. The particle size of Ni-Cu-

Abstract:
Les acides organiques (principalement l'acide formique (HCOOH) et l'acide acétique (CH3COOH) jouent un rôle clef dans la chimie de la troposphère. L'archivage glaciaire représente un moyen privilégié pour obtenir des informations permettant une meilleure compréhension globale du cycle de ces acides carboxyliques. Cependant, la méconnaissance des mécanismes d'incorporation de ces gaz dans la précipitation limite encore l'interprétation de ces archives en terme de variabilité de l'atmosphère passée. Cette étude a montré qu'il était possible d'utiliser la technique de la chambre à nébuliser pour

碩士<br>國立臺灣科技大學<br>材料科技研究所<br>95<br>In this research, Chemical Beam Epitaxy system using hydrozoic acid (HN3) as nitrogen source was used to grow InN on ITO/Glass and C-plane sapphire substrates. And the optical property of InN was carefully characterized. Poly-crystalline InN thin film was successfully grown on ITO/Glass substrate. The effect of III/V ratio, substrate temperature and growth time were carefully investigated by XRD and SEM. The absorption spectrum shows that the band gap of crystalline InN grown on ITO/Glass was 1.5 eV. From the PL spectrum, an emission from 0.5 to 0.8 eV was ob

Abstract:
We have previously shown that the arcuate organization of cell fates within the ventral midbrain critically depends upon the morphogen, Sonic Hedgehog (SHH), which is secreted from a signaling center located along the ventral midline, called the floor plate (FP). Thus, it is ultimately the specification of the FP that is responsible for the patterning and specification of ventral midbrain cell fates. Interestingly, we have found that the chick midbrain FP can be divided into medial (MFP) and lateral (LFP) regions on the basis of gene expression, mode of induction and function. Overexpression o
