Abstract: Perovskite films are known to be useful in many different technologies, including solar panels and memristors. Most perovskites contain lead which is undesirable for many reasons. It has been found that bismuth can be used in place of lead in preparing perovskite thin films. Additionally, when chemical vapor deposition is used to prepare the films instead of traditional solution phase methods, the films show greatly improved performance in electronic applications. Additionally, the present disclosure is directed to the use of perovskites in memory devices.

Abstract: A method of producing submicrometer- to micrometer-sized spherical particles, the method comprising dissolving a lithium salt and a metal salt in water or alcohol forming a precursor solution, spraying the precursor solution to form fine aerosolized droplets, flowing the aerosolized droplets into a pyro lysis flame producing submicrometer- to micrometer-sized spherical particles. The submicrometer- to micrometer-sized spherical lithium-metal oxide powders produced are cathode materials for Li-ion batteries.
Abstract: A system detects a covert timing channel on a combinational structure or a memory structure. The system identifies the events behind conflicts, and constructs an event train based on those events. For combinational structures, the system detects recurrent burst patterns in the event train. The system determines that a covert timing channel exists on the combinational structure if a recurrent burst pattern is detected. For memory structures, the system detects oscillatory patterns in the event train. The system determines that a covert timing channel exists on the memory structure if an oscillatory pattern is detected.

The methods comprise determining binding of each polypeptide with respect to each binding pool of a plurality of binding pools, wherein each binding pool comprises one or more probes which bind a structure comprised by a protein or polypeptide. In some aspects, polypeptides can be denatured and separated into individual polypeptide strands and immobilized on a solid support prior to determining binding of the binding pools. A protein, polypeptide or polypeptide strand can be identified by searching, in at least one database, for a protein or polypeptide sequence comprising binding pool targets either identical to or most similar to the binding pool targets comprised by the protein, polypeptide or polypeptide strand to be identified. Kits for identifying proteins, polypeptides and polypeptide strands are also disclosed.

Abstract: A sensor system includes a sensor module that is embedded in a target environment and a signal system. The sensor module includes an active sensor of a first type that detects a target element in the target environment and a reference sensor of the first type that prevents detection of target elements by the reference sensor. The active sensor and the reference sensor receive an ultrasonic signal and respectively generate a first response signal and a second response signal. The first response signal is at least partially as a function of the detected target element. The signal system includes an ultrasonic transducer that generates the ultrasonic signal and receives the first and second response signals, and a controller communicatively coupled to the ultrasonic transducer. The controller identifies the detected target element based at least partially on the first and second response signals.
