Abstract: Durable antibacterial coatings are prepared by inter-diffusing zwitterionic polyurethane in acrylic polyurethane. Bacterial attachment is substantially eliminated from the surface of the coatings due to the hydrophilicity of the zwitterionic polyurethane. Long-term antibacterial properties were observed for both Gram-negative and Gram-positive bacteria even when the coatings were constantly challenged by mechanical abrasion.

Abstract: Nano-sized zeolites may be prepared using germanium oxide (GeO2) as a component of the overall synthesis composition. This is accomplished by the addition of GeO2 as an inexpensive reagent for the synthesis gel. Most of the Ge is retained in the synthesis mixture and the small amount incorporated in the zeolite solid (Si/Ge>100) does not have an appreciable impact on zeolite acidity or other physicochemical properties. The methods disclosed herein circumvent challenges to prepare nano-sized zeolites having dimensions less than 100 nm.

Abstract: Methods and systems for providing depth-resolved real-time visual feedback to a physician during cosmetic dermal filler injections with micrometer spatial resolution utilizing a noninvasive optical coherence tomography/elastography, 2D-3D virtual and real time system. This system can be automated to direct proper volumes and viscosity of the necessary injection substances. The methods and systems allow for assessment of the elasticity of the tissue before and after the injection to evaluate the efficacy of the injection, with predetermined virtual results before and matched post injection images. The elasticity assessment method preferably utilizes a focused air-pulse to induce a micrometer scale displacement in the skin and the optical coherence tomography system to image this displacement. By utilizing a model-based reconstruction method, the viscoelasticity of the tissue at a specific measurement position can be obtained and virtual and post injection real time projections can be imaged.

Abstract: A method including capturing carbon dioxide (CO2) from air (e.g., atmosphere) in an absorber in which the air contacts a base (e.g., a hydroxide, such as potassium hydroxide KOH and/or sodium hydroxide (NaOH)) to produce a carbonate (e.g., potassium carbonate (K2CO3) and/or sodium carbonate (Na2CO3)); precipitating one or more (e.g., carbonate) salt from an aqueous solution comprising salt (a brine) to provide an aqueous solution comprising a chloride (e.g., potassium chloride (KCl) and/or sodium chloride (NaCl)); using electrochemical regeneration to convert the chloride to electrochemically regenerated product comprising the base (e.g., KOH and/or NaOH); and recycling at least a portion of the electrochemically regenerated product comprising the base to the capturing of the CO2 from the air. A system for carrying out the method is also provided.

Abstract: A method and system for quench detection in high temperature superconductors, such as REBCO (rare-earth barium copper oxide), before thermal runaway. A REBCO superconducting tape is excited as a transmission line forming standing waves. A quench may then be detected in response to detecting a disturbance of the standing waves. In this manner, quench in high temperature superconductors, such as REBCO, is rapidly detected before thermal runaway.

Abstract: Discussed herein are methods of orienting one-dimensional and two-dimensional materials via the application of stationary and rotating magnetic fields. The oriented one-dimensional and two-dimensional materials may exhibit macroscopic properties, and may be employed in various measurement devices as well as thermal and electrical shielding applications or battery devices. A single 1D or 2D material may be suspended in another material such as dionized water, polymer(s), or other materials during the orientation, and the suspension may remain as a liquid or may be solidified or partially solidified to secure the oriented material(s) into place. The 1D and 2D materials that respond to the magnetic orientation may further cause other elements of the suspension to be oriented in a similar manner.

Abstract: Ultra near-field index modulated plasmonic nano-aperture label-free imaging methods and techniques are useful for imaging and detection of biological microparticles and nanoparticles such as circulating tumor exosomes (CTEs), bacteria and vimses. The methods and techniques utilize a high-density array of gold, silver, or gold/silver alloy nanodisks, in some cases on an undercut or invisible substrate. Given the relatively large nanodisk dimensions, the nanodisk array may feature a significantly blue-shifted LSPR extinction peak due to both far-field plasmonic coupling and substrate undercut. The ultra near-field imaging methods have the ability to image nanoparticles as small as 25 nm.

The MR film may be positioned on a substrate, where the edges of the MR film are in contact with leads. Additionally, the leads may be in contact with pads. The sensors may provide quasi-digital readout that enable greatly enhanced sensitivity. In some embodiments, biosensors may be arranged as array of sensors. The array of sensors may be arranged as a symmetric or asymmetric N1×N2 array, where N1 and N2 are integers, N1 represents the number of sensors linked together in series, and N2 represents the number of sensor sets in parallel, where each sensor set may comprise one or more sensors. Further, the array of sensors may be coupled to a voltmeter, which may be a single voltmeter in some cases that allows the sensors to all be probed simultaneously.

Abstract: Embodiments of the present disclosure pertain to methods of treating or preventing a cancer in a subject by administering to the subject an immunogenic peptide and/or a nucleotide sequence that expresses the immunogenic peptide. Thereafter, the administered or expressed immunogenic peptide elicits an immune response against cells associated with the cancer. The immunogenic peptides contain a neoantigenic region and are expressed by chimeric nucleotide sequences derived from cells associated with the cancer. The chimeric nucleotide sequences have a higher prevalence in cancer cells when compared to non-cancer cells. Further embodiments pertain to compositions that include the immunogenic peptides of the present disclosure and/or a nucleotide sequences that express them.
