72. Three dimensional aspects of droplet coalescence during dropwise condensation on superhydrophobic surfaces
Topic: Chemistry
Published: 8/24/2011
Authors: Konrad Rykaczewski, John Henry Scott, Sukumar Rajauria, W Robert Ashurst, Jeff Chinn, Amy Chinn, Wanda Jones
Abstract: We report formation of nano-to-microscale satellite droplets in the geometrical shadow of high contact angle primary drops during dropwise water condensation on a nanostructured superhydrophobic surface. The primary drops contribute to the heat tran ...

75. Effect of sample conditioning on the water absorption of concrete
Topic: Chemistry
Published: 8/1/2011
Authors: Javier Castro, Dale P Bentz, Jason Weiss
Abstract: ASTM C1585 is commonly used to determine the absorption and rate of absorption of water in unsaturated hydraulic cement concretes. ASTM C1585 preconditions the samples for a total of 18 days. Unfortunately however, the range of relative humidities th ...

77. Optimization of Cement and Fly Ash Particles to Produce Sustainable Concretes
Topic: Chemistry
Published: 8/1/2011
Authors: Dale P Bentz, Andrew Hansen, John Guynn
Abstract: In the drive to produce more sustainable concretes, considerable emphasis has been placed on replacing cement in concrete mixtures with more sustainable materials, both from a raw materials cost and a CO2 footprint perspective. High volume fly ash c ...

Topic: Chemistry
Published: 7/23/2011
Authors: Tara M Lovestead, Thomas J Bruno
Abstract: Victims of crimes are often buried in clandestine graves. There are several techniques for finding buried bodies or the scattered remains of a victim; however, none of these methods are very reliable or work in all scenarios. One way to detect grav ...
