Inhibitors of the BfrB-Bfd Complex for Killing Biofilm Bacteria

BACKGROUND Biofilms are communities of microbes adhering to a surface and often embedded in an extracellular matrix. As a result of this structure, biofilms exhibit resistance to both host immune responses and antibiotics. Approximately 80% of human bacterial infections involve biofilms; this can take the form of chronic wound infections, chronic...

3D Printing System for Vertical Construction

BACKGROUND Most 3D printing systems sequentially apply their layers from above. Such systems have distinct challenges when creating vertically reinforced concrete structures such as walls or columns. Most vertical reinforced concrete structures contain reinforcing bars that give the structure strength after the concrete has cracked. It is possible...

Additive Manufacturing Using Ionized Particles

BACKGROUND Modern 3D printers can print intricate shapes at fine detail, but their low print speed enables them to only be used for prototyping or, at best, limited batch manufacturing. As an example, the fasted current metal printers can print a volume of about 60 cm³/hr. per nozzle or laser. This equivalent to about 8 grams/minute for a...

Method and Implementation of Dispersion Compensation in Terahertz Wireless Signals

BACKGROUND A broadband, wireless terahertz signal is comprised of a multitude of individual frequency components. These frequencies travel at different speeds through the atmosphere, which causes the composite signal to spread out in time, as some frequency components arrive later than others. This is an undesirable effect known as “group delay...

TFT-less IR-driven OLED Display

BACKGROUND TV screen sizes are getting bigger and bigger every year. However, manufacturers using organic light-emitting diode (OLED) technology face a big challenge in fabricating TV screens over 100 inches at reasonable cost. Unlike the OLED process which is compatible with low-cost, low-temperature, and large area processing methods including...
