    Abstract: A dispersing agent or dispersant formed as a block copolymer for use in surface coating compositions, such as architectural paint compositions, that can alter its properties as a result of changes in environmental conditions is provided. These stimuli-responsive copolymers are synthesized with properties that can be controlled based on number of blocks and block length and/or as a function of pH and temperature. The addition or these copolymers to coating compositions including other additives, such as pigments and/or fillers, can decrease settling rate, control viscosity, and control interfacial activity of the additives in the compositions.

    Abstract: An improved chemical probe for the detection of the amino acid citrulline combines: 1) a reactive head formed of 1,3-dicarbonyl moiety that reacts with a citrulline side chain in an improved manner compared to currently used 1,2-dicarbonyl moieties; and 2) a modular action of the probe where citrulline side chains are labeled first using reactive heads described above, and attachment of a read-out subunit or tag, be it a fluorophore, a nanoparticle, or an antigen is performed separately. The modular nature of the chemical probe increases the sensitivity of the probes due to their smaller size. Additionally, the chemical probes of the present disclosure allow the same sample to be analyzed using a variety of read-out methods.

    Abstract: The present invention provides a system of wind turbines connected to a single unit electric generator to produce electrical power whereby the wind turbine blades rotate coaxially with a main rotor shaft instead of perpendicular to the shaft axis. In this respect, the wind turbine rotor can face the wind from any direction and does not need to be pointed into the wind to be effective, thus, eliminating the need for a yaw system. Moreover, translation of mechanical to torque of the main rotor drive allows the drive components such as the gearbox and generator to be placed near the ground of each wind turbine improving accessibility for maintenance.
