Abstract: Engines operating using multiple, different types of fuel are described. The engines may include components that control the introduction of fuels and/or reduce premature pre-ignition of fuels, such as a fuel comprising a percentage of hydrogen. The described hydrogen-fueled engines have a reduced carbon footprint.

Abstract: This present disclosure provides pharmaceutical compositions for delivering recombinant adeno-associated virus (rAAV) particles, generally comprising a buffer, a monovalent salt, a poly hydric alcohol, and a triblock copolymer surfactant.

Abstract: Provided are methods of separating full capsid particles and empty capsid particles in a viral capsid preparation using an anion exchange medium. Methods may involve using a wash solution comprising a quaternary ammonium salt. Methods include applying a viral capsid preparation to an anion exchange medium, combined with multiple quaternary ammonium salt wash solutions.

Abstract: A four-stroke opposed-piston engine contains a cylinder having a periphery and a combustion chamber and an ignition system, wherein the ignition system is fixed to the cylinder periphery and at least partially contained within the combustion chamber. During combustion, the ignition system is adapted to locate a spark within a fuel-rich predetermined region of the combustion chamber.

Abstract: An inventive opposed piston engine is provided. The inventive engine includes an inventive mechanism that enables adjustment of a compression ratio of the engine.

Abstract: A combined heat, cooling and power system is configured to generate energy as well capture a large percentage of energy that would otherwise be lost using components, including heat transfer components, embedded within a vessel to transfer energy in the form of heat to liquid within the vessel.

Abstract: Pressurized air may be generated within a lightweight opposed piston engine without the need to make use of a supercharger. The lightweight engine may be combined with one or more lightweight micro-generators.

Abstract: An opposed piston engine includes an engine housing (20), at least one cylinder housing (300) coupled to the engine housing, and a cylinder (210) supported by the at least one cylinder housing (300). The cylinder has a first end and a second end opposite the first end. Each of the first and second cylinder ends is directly supported by the engine housing (20).

Abstract: An opposed-piston engine optionally contains an ignition system that is at least partially contained within the combustion chamber to enhance the combustion efficiency of a fuel-air mixture within the combustion system. More specifically, the ignition system contains at least one spark plug having an elongated center electrical delivery electrode, and, an elongated ground electrode. Accordingly, the elongated electrodes extend from an area adjacent to the inner periphery of the cylinder to a radially central area within the combustion chamber. Yet further, a cooling jacket is incorporated to provide cooling of the spark plug.

Abstract: A four-stroke opposed piston engine contains a drive train containing two outer crank shaft gears, and two inner synchro gears, wherein the inner synchro gears are twice the diameter of the outer crank shaft gears. Additionally, novel piston faces are presented that when fixed on opposed pistons, create annular cavities that form advantageous combustion chambers when the pistons are at top dead center.

Abstract: An opposed-piston engine contains opposed pistons wherein each piston has a piston face containing a recess. The recesses formed in the piston faces define a combustion chamber when contained within a cylinder. An ignition system is at least partially contained within the combustion chamber to enhance the combustion efficiency of a fuel-air mixture within the combustion system.
