Strengthening and Sintering of Silica Nanoparticles — Presentation Detail — Celebration of Scholars

Instructions

Student presentations must have a faculty sponsor.

Abstracts must include a title and a description of the research, scholarship, or creative work. The description should be 150-225 words in length and constructed in a format or style appropriate for the presenter’s discipline.

The following points should be addressed within the selected format or style for the abstract:

A clear statement of the problem or question you pursued, or the scholarly goal or creative theme achieved in your work.
A brief comment about the significance or uniqueness of the work.
A clear description of the methods used to achieve the purpose or goals for the work.
A statement of the conclusions, results, outcomes, or recommendations, or if the work is still in progress, the results you expect to report at the event.

Presenter photographs should be head and shoulder shots comparable to passport photos.

Abstract

The use of crystals made from silica nanoparticles can be used as a stationary phase for chemical separations. Silica colloidal crystals are loosely held together, and unless treated properly with high temperature sintering they will disperse when exposed to aqueous solutions. The goal of this work is to form these crystals and increase their strength without the use of high temperatures. The silica nanoparticles were deposited via vertical evaporative deposition from an ethanol solution. One of the problems encountered was the formation of a well-ordered crystal. The issues included horizontal drying lines as well as vertical cracks in the crystals. To mitigate these problems, a miniature deposition table was fabricated from aluminum. Following the formation of the colloidal crystals, various treatments were applied to achieve higher strength.
