Abstract: Disclosed are methods and compounds useful for forming coatings applied to porous and non-porous surfaces to make the surface antimicrobial and to protect against contaminants. The coatings are formed from phenolic compounds present in a solvent either alone or in combination with other compounds, such as metallic salts.

Abstract: A method of preparing a Metal Organic Framework (MOF) with an acoustically-driven microfluidic platform, the method comprising: depositing a liquid comprising MOF precursors on a piezoelectric substrate of an acoustic microfluidic platform, the MOF precursors comprising a metal ion and an organic ligand, applying acoustic irradiation to the liquid to induce azimuthal liquid recirculation, which causes formation of the MOF within the liquid, and isolating the MOF.

Abstract: Detecting physical forensic evidence on a surface includes contacting the surface with a composition, the composition including a rare-earth metal and a chelator. The composition contacting the surface is illuminated with electromagnetic radiation configured to cause the composition to fluoresce in a pattern indicative of physical forensic evidence. The pattern indicative of physical forensic evidence can then be captured. The composition can be made by combining a rare-earth metal, a chelator, and a solvent to form a solution, precipitating the rare-earth metal and the chelator in the solution, and isolating the precipitate of the rare-earth metal and the chelator from a remainder of the solution. The resulting composition includes a porous metal-organic framework of a rare-earth metal and a chelator, where the pores range in diameter from about 0.01 nm to about 50 nm.

Abstract: Play stations or terminals for playing computerized games having at least one game lot, each game lot having a plurality of chances including a finite number of losing chances and a finite number of winning chances. The plurality of chances are provided for random purchase via one of the play stations. The preferred play station including a display that notifies the player of real time status information including: 1) the frequency of game lot chances purchased on the network; 2) the average profit or payout expectancy; 3) the actual profit or payout experience; and/or 4) the number of other players actively purchasing chances from the same game lot on the network. The present invention further includes methods of displaying such real time status of a computerized game on a computer gaming network.

Abstract: A computerized gaming device and method of playing casino-type games of chance wherein a player chooses a game to play from a plurality of games displayed on a video screen. Each game has a finite number of chances per deal and a video display of the chances of winning when a deal is new, the percentage of winning chances remaining, the possible winning symbol combinations, and how many major winning chances remain. In addition, a displayed record is kept of the player's cash credit with a print out of wins and losses when he quits to claim any winnings. A provision is made to retire a deal or game whenever all the major winning chances have been won or when there are no more winning chances remaining. The player can quit at any time or call for a new deal screen after playing at least one chance in a deal.
