Abstract: Novel 2D organic-inorganic hybrid perovskites, including (4-CF3—PMA)2PbI4, that emit in the blue spectral region, and methods for making same. The CF3-substituted material exhibits a ˜0.16 eV larger bandgap than corresponding halogen-substituted materials. This family of materials offers a degree of freedom in tuning 2D perovskites to specific bandgaps for optoelectronic applications. These materials are highly stable, easily synthesized, and do not suffer from phase separation.

Abstract: A method, apparatus and system for medium access control is provided. Time slots configured to include mini slots at the beginnings thereof. Devices are assigned time slot, mini slot combinations as transmission opportunities. A device can attempt to use a transmission opportunity when it has a packet to send, by beginning data transmission in its assigned slot and mini slot and potentially continuing the transmission up until the end of the assigned slot. If another device is already transmitting in the assigned slot, the device refrains from using its transmission opportunity. Higher priority devices can be assigned transmission opportunities corresponding to earlier mini slots within a slot. In some embodiments, multiple devices can be assigned the same transmission opportunity and a collision detection mechanism can be employed. In some embodiments, all devices detect if a slot is idle and advance the beginning of the next slot upon such detection.

Abstract: Methods and devices are described that enable a device to generate a message including a multimodal composition, and to output the message on a device. The multimodal composition is generated by first selecting a first element belonging to a first output modality. The multimodal composition is further generated by selecting at least one second element belonging to a second output modality to associate with the first element, the combination of the first element and the second element being the multimodal composition.

Abstract: A method for fabricating a Bismuth-doped silica-based optical composition. The method has the steps of: depositing SiO2 to obtain a silica material, soaking the silica material into an aqueous Bismuth solution, incorporating GeO2 into the silica material, and vitrifying the silica material at a temperature greater than 1500° C. to obtain the Bismuth-doped silica-based optical composition. In some embodiments, the fabricated Bismuth-doped silica-based optical composition has GeO2 of greater than 12 mol % (such as 19 mol %) and is suitable for transmitting therethrough optical signals of one or more of E and S bands.
