Abstract:

The structuring of porous silica materials at the nanometer scale and their surface functionalization are important issues of current materials research. Many innovations in chromatography, catalysis and electronic devices benefit from this knowledge. The work at hand is dedicated to the targeted design of functional organosilica materials. In this context a new precursor concept based on boron-silanes is presented. These precursors combine the properties of a structure directing group and a silica source by covalent borane linkage. Formation of the precursor is easily realized by a sequential

Abstract:

In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different oxidation number. Only a single metallic phase catalyst could be prepared successfully by using ion exchange.

Abstract:

Polymer-based carbide-derived carbons (CDCs) with combined micro- and mesopores are prepared by an advantageous sacrificial templating approach using poly(methylmethacrylate) (PMMA) spheres as the pore forming material. Resulting CDCs reveal uniform pore size and pore shape with a specific surface area of 2434 m2 g−1 and a total pore volume as high as 2.64 cm3 g−1. The bimodal CDC material is a highly attractive host structure for the active material in lithium–sulfur (Li–S) battery cathodes. It facilitates the utilization of high molarity electrolytes and therefore the cells exhibit good rate

For this report, the ordered mesoporous carbon CMK-3 was taken as a support for LiAlH₄ realized by a solution impregnation method to improve the hydrogen desorption behavior of LiAlH₄ by nanoconfinement effects.

碩士<br>國立成功大學<br>化學工程學系碩博士班<br>95<br>In this study, cadmium sulfide quantum dots (CdS QDs) were used as a sensitizer of dye-sensitized Solar Cells (DSSCs). CdS QDs were deposited on the titania photoelectrodes using chemical bath deposition (CBD). Here, we focused on the discussion of cell efficiency for different structure titania photoelectrodes with micro/nano mutilayer porous structure made by spin coating method.From the experimental results, the assembly of the larger size titania particles (PT-501-A, 100nm) on the outer layer was not only with larger holes and scattering effect, but also

Preparation of hierarchical zeolites for fine chemical synthesis Author: Bc. Ondřej Veselý Supervisor: Mgr. Pavla Eliášová, Ph.D. Prague, 2019 Abstract (in english): The thesis is focused on synthesis of hierarchical (micro-mesoporous) zeolites by several different methods and their application in catalytic reactions. Performance of hierarchical materials prepared by different approaches has been investigated, as well as the effect of framework topology and type of acidity on the outcome of the reactions. The work was elaborated in the Department of Physical and Macromolecular Chemistry of Cha

Abstract:

Cancer is a major health care problem with growing incidence, not only at a national level but also worldwide. Due to this urgency in reducing cancer prevalence, the scientific community has put forward a great attention in the search for novel anti-cancer treatments, particularly, in the development of nanocarriers capable to control and promote drug delivery to target cells. These drug delivery systems are capable to overcome the limitations presented by the conventional chemotherapeutic treatments. Among the various types of nanocarriers developed so far, mesoporous silica nanoparticles (MS
