Abstract: Aspects of the present disclosure configure a memory sub-system controller to receive information from a host about invalidated memory addresses. The controller receives, from a host, data identifying a set of storage locations associated with invalidated data stored in a set of memory components and, in response to receiving the data, performs staging activity for the invalidated data stored in the set of storage locations. The controller receives, from the host, a trim command for one or more storage locations in the set of storage locations and performs trim operations for the one or more storage locations for which the staging activity has already been performed.

Abstract: Ruggedized luminescent nanoparticle tracers have luminescent nanoparticle cores coupled to a luminescent substrate. The substrate is a large-particle size phosphor, while the nanoparticles are photoluminescent quantum dots (QDs) whose emission spectra can be tuned based on their chemical composition, size, and fabrication (e.g., dopants). The QDs are encapsulated by a protective layer to form a nanoparticle core. The protective layer can shield the QDs from external environments that would otherwise damage the delicate QDs. The substrate is also encapsulated by a protective layer, and the protective layer of the nanoparticle core is coupled to the protective layer of the substrate via a molecular linker to form a tracer particle complex. The tracer particle complexes can be disposed in a silicate suspension for subsequent use.

Abstract: A beta-voltaic device made up of silica covered scintillating particles incorporated within an isotope absorbing layer to produce an improved power source. Lost beta particles are converted to UV light which is also converted to power in a beta-voltaic converter. The addition of the scintillating particles effectively increases the power efficiency of a BV device while maintaining the slim profile and smaller size of the power source. This arrangement makes possible implementation in space, defense, intelligence, medical implants, marine biology and other applications.

Abstract: Methods for forming thin, pinhole-free conformal metal layers on both conducting and non-conducting surfaces, where the morphology and properties of the metal layers are tuned to meet desired parameters by adjusting the concentration of ionic liquids during the deposition process. The formed metal films contain tunable properties for solar and electronic use and provide specific advantages for non-conducting surfaces, which are otherwise unsuitable for electroplating without the presence of the formed metal films. The disclosed methods do not require the presence of a voltage or external electric field but form the metal films through an electroless technique using electrostatic interactions between negatively charged nanoparticles. In addition, the disclosed methods are compatible with solution phase processing and eliminate the need to transfer the surfaces into a vacuum chamber for a chemical or physical vapor deposition to form a metal layer.

Abstract: Methods and apparatus for controlling landing gear retract braking are described. A controller determines wheel speed data corresponding to a speed of a wheel of a landing gear. The controller determines wheel deceleration data corresponding to a rate of change of the wheel speed data. The controller generates a first control signal in response to the wheel deceleration data being greater than a wheel deceleration threshold. The first control signal initiates a wheel deceleration regulation process, the wheel deceleration regulation process to cycle an antiskid valve between a first valve position to release brake pressure from the wheel and a second valve position to cease releasing the brake pressure from the wheel. The controller generates a second control signal in response to the wheel speed data being less than a wheel speed threshold. The second control signal terminates the wheel deceleration regulation process.
