Paper Rolls Art By Anastassia Elias

Anastassia Elias is an assistant Professor with the Department of Chemical and Materials Engineering at the University of Alberta. As a PhD student in Electrical and Computer Engineering she developed techniques for patterning a variety of materials on the micro and nanoscale to create thermally and chemically-responsive microactuator devices. During this degree she spent nearly 2 years in the Netherlands undertaking collaborative research with the Technische Universiteit Eindhoven and Philips Research. She also worked together with researchers from Brown University to study the alignment of liquid crystals in porous templates.
After completing her thesis work she lived in the US for 6 months before returning to Edmonton in August 2007 as a postdoctoral fellow under the supervision of Dr. Jillian Buriak of the NRC National Institute for Nanotechnology and the Department of Chemistry. During this appointment she designed and fabricated microfluidic devices for culturing human cortical neurons, as a part of a collaboration between our group and the group of Dr. Fabrizio Giuliani in the Department of Medicine. She also completed a study to investigate the stability of gold nanoparticles in human blood products.
Toilet paper is a soft paper product (tissue paper) used to maintain personal hygiene after human defecation or urination. However, it can also be used for other purposes such as absorbing spillages or craft projects. It differs in composition somewhat from facial tissue, and is designed to decompose in septic tanks, whereas some other bathroom and facial tissues do not. Most septic tank manufacturers advise against using paper products that are non-septic tank safe. Different names and slang terms are used for toilet paper in countries around the world, including "loo roll/paper," "toilet roll," "dunny roll/paper," "bathroom/toilet tissue," "TP," or just "tissue." Toilet paper can be one, two, three, even more -ply, meaning that it's either a single sheet or two, three sheets placed back-to-back to make it thicker, softer, stronger and more absorbent. Color, scents, and embossing may also be added, but fragrances sometimes cause problems for consumers who are allergic to perfumes. The biggest difference between toilet papers is the distinction between virgin paper products, which are formed directly from chipped wood, and those made from recycled paper. Most toilet paper, however, whether virgin or recycled, is wrapped around recycled cardboard cylinders.
