Ultrasonic Technologies, Inc. (UST) is a small R&D and manufacturing company located in Wesley Chapel, Florida, specializing in ultrasonic quality and process control equipment for solar cells, fuel cells, health and defense industries (www.ultrasonictech.com). Dr. Sergei Ostapenko, President and CEO of the company will serve as a Principal Investigator of the Incubator 11 project. He has many years of experience in technology development, and previously served as PI in NSF and DOE funded…

2.1. Biocellulose definition Cellulose is the main component of plant cell wall. Some bacteria produce cellulose (called biocellulose or bacterial cellulose). Plant cellulose and bacterial cellulose have the same chemical structure (Fig.2.1), but different chemical and physical properties (Lin et al., 2016). The molecular formula of bacterial cellulose (C6H10O5)n is the same as that of plant cellulose, but their chemical and physical features are different. Biocellulose is preferred over the…

PERIODONTOLOGY LLLT stimulates fibroblasts for faster regeneration of soft tissue, while providing analgesia and a modulation of the inflammatory chemicals that cause pain and discomfort. LLLT when used in conjunction with surgical lasers for treatment such as gingivectomy, periodontitis and periodontal surgery, have shown great promise in achieving improved clinical outcomes. A 2006 study12 showed a statistically significant decrease in pocket depth at 21 and 28 days postsurgery. Moreover,…

1. Introduction Silicified wood is normally formed close to the surface due to the infiltration of buried wood with mineral-rich water and the associated deposition of minerals (Kim et al., 2009). Two typical geological environments have been reported, 1) trees transported by streams and rivers then buried in the fluvial sediments (e.g., Weibel, 1996; Fielding and Alexander, 2001; Parrish and Falcon-Lang, 2007; Hartmann et al., 2010), and 2) ash from volcanic eruptions buries trees while felled…

The carbohydrates present on the cells surface can act as a receptor for many pathogens to facilitate cell-cell adhesion through which humans can be infected, for example, mannose binds pathogenic bacteria E. coli and sialic acid binds influenza virus. Therefore, cell surface can be mimicked by preparing SAMs of carbohydrates to study and understand different types of binding and inhibition studies in vitro. SAMs of carbohydrates are also used for detecting disease biomarkers and carrying drugs.…

procedures, including large amounts of chlorinated solvents. Current efforts are directed toward fabrication of a fast, reliable and inexpensive toxin detection device. I am currently analyzing chlorinated toxins in coastal samples using portable Raman Spectroscopy method. Since Korea is a peninsula they also are surrounded by water which is being contaminated by these toxins because it comes from polluted runoff from industries to households. While doing that I also can be a representative for…

CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…
