Abstract: Platinum films can be obtained by aerosol assisted chemical vapor deposition (AACVD) using one or more Pt-dialkyldithiocarbamate complexes of formula Pt(S2CNR2), wherein R is independently alkyl, aryl, or alkaryl, particularly as single source precursors. Such methods may include heating a substrate to a deposition temperature above 150° C. in a reactor; and introducing into the reactor, at the deposition temperature, an aerosol including a platinum dithiocarbamate compound, salt, and/or solvate thereof, to thereby deposit the platinum layer on the substrate. The Pt(S2CNR2)-derived films have well-connected and defect-free surface topography and better catalytic performance, likely due to their high conductivity and reflectivity.

Abstract: A method and system are disclosed for a network node or wireless device (WD) to communicate with another WD or network node. The node or WD is configured to perform at least one timing measurement over a measurement period (T1) on signals transmitted between the node or WD and another node or WD and, during T1, determine if there is any change in a fixed time offset (FTO) used by the nodes for transmitting a reference signal. If there is a change in the FTO over T1, the network nodes or WDs are configured to perform an operational task and, if not, continue performing the timing measurement over T1. The operational tasks may include discarding the timing measurement, restarting the timing measurement, extending the measurement time, informing another node about a change in the FTO or informing another node about an action taken by the network node or WD.

Abstract: Techniques for increasing security for pre-authenticated links are disclosed herein. Computing systems that generate pre-authenticated links are configured to assign an entity identifier to pre-authenticated links to specify an entity permitted to access respective data through the pre-authenticated link. When activating a respective pre-authenticated link, an entity attaches an entity token to the request to prove an identity of the requesting entity. If the identity from the entity token matches the entity identifier, the computing system may grant access to the respective data.

Abstract: A method of making a nanostructured palladium thin film electrode is described. The method involves contacting a substrate with an aerosol comprising a solvent and a Pd(II) compound.

The nanostructured palladium thin film electrode is capable of detecting compounds such as hydrazine in an aqueous sample with a 10 nM limit of detection.

Abstract: A synthetic methodology for robust, nanostructured films of cobalt oxide over metal evaporated gold or similar material layer of, e.g., 50 nm, directly onto glass or other substrates via aerosol assisted chemical vapor deposition (AACVD). This approach allows film growth rates in the range of, e.g., 0.8 nm/s, using a commercially available precursor, which is ˜10-fold the rate of electrochemical synthetic routes. Thus, 250 nm thick cobalt oxide films may be generated in only 5 minutes of deposition time. The water oxidation reaction for such films may start at ˜0.6 V vs Ag/AgCl with current density of 10 mA/cm2 and is achieved at ˜0.75 V corresponding to an overpotential of 484 mV. This current density is further increased to 60 mA/cm2 at ˜1.5 V (vs Ag/AgCl). Electrochemically active surface area (ECSA) calculations indicate that the synergy between a Au-film, acting as electron sink, and the cobalt oxide film(s), acting as catalytic layer(s), are more pronounced than the surface area effects.

Abstract: A vehicle dash cam may be configured to execute one or more neural networks (and/or other artificial intelligence), such as based on input from one or more of the cameras and/or other sensors associated with the dash cam, to intelligently detect safety events in real-time. Detection of a safety event may trigger an in-cab alert to make the driver aware of the safety risk. The dash cam may include logic for determining which asset data to transmit to a backend server in response to detection of a safety event, as well as which asset data to transmit to the backend server in response to analysis of sensor data that did not trigger a safety event. The asset data transmitted to the backend server may be further analyzed to determine if further alerts should be provided to the driver and/or to a safety manager.
