AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

The thesis is divided into three parts. In part one, a rapid and facile synthesis route to synthesize mesoporous silica MCM-48 with the cubic Ia3d mesostructure has been developed using Gemini surfactant as a template with the aid of ultrasonic irradiation. The present synthesis route effectively reduces the total synthesis time from several days to only one day, which is much shorter than the conventional MCM-48 synthesis methods. We try to investigate the structural property as a function of ultrasonic time or hydrothermal time. The MCM-48 materials were characterized by a variety of techniques including powder X-ray diffraction (XRD), 29Si magic angle spinning (MAS) NMR, transmission electron microscopy (TEM), and scanning electron microscopy (SEM).

In part two, we use the optimal condition we have found in the previous part, and we have incorporated aluminum into the MCM-48 silica framework successfully up to a Si/Al ratio of 25.

In part three, the mesoporous silica SBA-15 materials containing carboxylic acid groups were used as a support to synthesize Pt nanoparticles. Various Pt loading levels from 3% to 10% on SBA-15 produced Pt nanoparticles with an average particle size of 3 to 4 nm.
