Decoding the Epigenetic Language of Life
22 Nov 2016 | Online Presentations | Contributor(s): Jian-Kang Zhu
I will describe work in my lab that has shed light on how DNA methyltransferases and demethylases are guided to specific sequences, and how the antagonistic actions of the enzymes are coordinated to generate proper DNA methylation patterns. I will also describe some of our recent work on how DNA...
Seeing Nano: Using Scanning Electron Microscopy (SEM) to View Nano-size Objects
02 Dec 2016 | Teaching Materials | Contributor(s): Samantha Andrews
Nano-size objects are smaller than the wavelength of light and because of this they cannot be viewed with a light microscope. Special tools are needed to see nanoscale objects, one of which is the scanning electron microscope. This activity will have students explore the types of images...
How Small is That?
02 Dec 2016 | Teaching Materials | Contributor(s): Jamie Ryan
This lab is designed to help students understand the size of nanoparticles compared to the size of other known quantities, such as a human being or a skin cell. After the size of nanoparticles is understood, the students will be challenged to come up with a way to “save”...
Understanding and Optimizing Exploratory Hydrothermal Reactions
22 Jan 2018 | Online Presentations | Contributor(s): Alex Norquist
In this work, an alternative approach that uses machine-learning algorithms trained on reaction data to predict reaction outcomes for the crystallization of templated vanadium selenites is demonstrated. Archived ‘dark’ reactions, both failed and successful attempts at hydrothermal...
Visualizing Crystal Structures: An interactive group classroom activity
11 Nov 2016 | Teaching Materials | Contributor(s): Susan Gentry, Tanya Faltens

Modeling of Inter-ribbon Tunneling in Graphene
11 Nov 2016 | Online Presentations | Contributor(s): Maarten Van de Put, William Gerard Hubert Vandenberghe, Massimo V Fischetti
IWCE presentation. In this paper we investigate the finite-size effect in nano-scaled graphene flakes. Improving on the bulk description, and because the structures are – atomistically speaking – large in size, we use the empirical pseudopotential method.
