    Abstract: Electrowetting-actuated optical shutters based on total internal reflection or beam steering. An electrowetting cell contains a conducting liquid and a non-conducting liquid configured to form a liquid-liquid interface extending to the inner walls of the cell. A beam of light is directed to the liquid-liquid interface at an angle near the total internal reflection angle of the interface. Voltage changes the shape of the liquid-liquid interface, without separating it from the inner walls of the cell. Thus, when depending on the voltage applied, the beam is either transmitted in part or substantially totally internal reflected.

    Abstract: Various embodiments of the present technology generally relate to reflection suppressors. More specifically, some embodiments use elastomeric materials doped with optical absorbers for temporary suppression of Fresnel reflections for multiple substrates spanning wide spectral and angular bandwidth. The refractive index of the elastomer can be tuned to match a substrate and thereby minimize reflection. Some embodiments can use the addition of different absorptive dopants to allow for either broadband or wavelength-selective reflection suppression. As performance is limited only by index mismatch, both spectral and angular performance significantly exceed that of anti-reflection coatings. After use, these light traps may be removed and reused without damaging the substrate. These films have uses in spectroscopic ellipsometry, holography, and lithography.

    Abstract: A method for securing a first interacting element to a second interacting element is provided. The first interacting element includes a lateral surface established by a first surface and a second surface and at least a portion of the lateral surface includes a thread receipt. The second interacting element includes a distal end and a proximal end that establishes a body therebetween. The body has a thread that is configured to at least partially engage with the thread receipt of the first interacting element. The second interacting element is then inserted at least partially through the surface of an object. The thread receipt of the first interacting element is then abutted adjacent to the thread of the second interacting element. Upon rotation of the second interacting element the thread of the second interacting element at least partially engaged with the thread receipt of the fist interacting element.

    Abstract: Antimicrobial agents, including antimicrobial peptides (AMPs) and uses thereof. Compositions and methods of using dermaseptin-type and piscidin-type antimicrobial peptide variants that demonstrate activity and improved therapeutic indices against microbial pathogens. The peptide compositions demonstrate the ability to not only maintain or improve antimicrobial activity against bacterial pathogens including Gram-negative microorganisms Acinetobacter baumannii and Pseudomonas aeruginosa, but also significantly decrease hemolytic activity against human red blood cells. Specificity determinants within the AMPs change selectivity from broad spectrum antimicrobial activity to Gram-negative selectivity.
