Abstract: An intravascular fluid movement device that includes an expandable member having a collapsed, delivery configuration and an expanded, deployed configuration, the expandable member having a proximal end and a distal end, a rotatable member disposed radially and axially within the expandable member, and a conduit coupled to the expandable member, the conduit at least partially defining a blood flow lumen between a distal end of the conduit and a proximal end of the conduit, the conduit disposed solely radially inside of the expandable member in a distal section of the expandable member.

Abstract: The disclosure features novel lipids and compositions involving the same. Nanoparticle compositions include an ionizable lipid, a phospholipid, a first sterol or a tocopherol, and optionally a second sterol different from the first sterol. Nanoparticle compositions further including therapeutic and/or prophylactics such as RNA are useful in the delivery of therapeutic and/or prophylactics to mammalian cells or organs to, for example, regulate polypeptide, protein, or gene expression.

Abstract: An article of ionizing radiation shielding and a method of its manufacture are disclosed. In an example, the method of manufacturing the article of ionizing radiation shielding comprises mixing a first particulate of a first material with TEOS or other suitable alkoxides of silicon to obtain a first powder. The first material comprises a metal, semi-metal, metalloid, or oxide of one or more elements having an atomic number of 50 through 83. The method further comprises hydrolyzing the first powder to obtain first particles comprising the first particulate coated with an exterior layer comprising silica and/or silica oxide. The method further comprises reacting the first particles with TEVS or other suitable silane coupling/adhesion promoting agent to obtain first reacted particles. The method further comprises combining the first reacted particles with an uncured silicone solution to obtain a mixture; and curing the mixture into a cured form.

Abstract: A method can be used to control the operation of one or more non-light-emitting, variable transmission devices. In an embodiment, a method of operating a plurality of non-light-emitting, variable transmission devices can include receiving requests for requested visible transmittance for the non-light-emitting, variable transmission devices; determining operating parameters for the non-light-emitting, variable transmission devices; and operating the non-light-emitting, variable transmission devices at the operating parameters, wherein the operating parameters for the non-light-emitting, variable transmission devices are different.

Abstract: A method of controlling an electroactive device can include operating the electroactive device at an operating parameter for a first period of time, applying a switching voltage having a first magnitude and a first polarity to the electroactive device for a second period of time, and applying a step-wise overshoot voltage having a second magnitude and a second polarity to the electroactive device for a transition period of time. The first magnitude can be greater than the second magnitude, and the first polarity can be the same as the second polarity. The method can also include applying a reverse overshoot voltage having a third magnitude and a third polarity to the electroactive device. The third polarity can be the opposite the second polarity.

Abstract: Radiopaque bismuth particles and methods of making and using the radiopaque bismuth particles are disclosed. The radiopaque bismuth particles include an elemental bismuth core and an outer coating comprising one or more coating agents. Disclosed radiopaque bismuth particles are suitable for use in surgical sponges and plastic objects.

Abstract: The present invention describes a highchair bib and debris catch device. The highchair bib forms a barrier over the upward facing surfaces of the highchair seat and over the child's torso that prevents food and liquids from coming in contact with the highchair seat and the child's torso and legs. It catches any mess that lands on it and prevents it from falling to the floor. The preferred embodiment of the highchair bib is designed such that it can easily be mounted on a wide variety of highchairs with no modification of the highchairs required.
