Abstract: In order to inhibit the growth of fungi, such as Madurella mycetomatis, gold nanoparticles are synthesized and capped with an extract of Reseda arabica. The gold nanoparticles capped with the extract of Reseda arabica are made by adding the extract of Reseda arabica to an aqueous sodium tetrachloroaurate (NaAuCl4) solution to reduce the sodium tetrachloroaurate and form a suspension of gold nanoparticles capped with the extract of Reseda arabica. The extract of Reseda arabica acts as a reducing and stabilizing agent while also functionalizing the surfaces of the gold nanoparticles to cap the surfaces. The suspension may be boiled, followed by removal of the gold nanoparticles capped with the extract of Reseda arabica from the suspension. To treat a Madurella mycetomatis infection, an effective dose of the gold nanoparticles capped with Reseda arabica extract may be administered to a patient in need thereof.

Abstract: Methods, systems, and devices for wireless communication are described. Aspects of the disclosure describe narrow beam-based channel access that enables a device to communicate in a shared radio frequency spectrum band without performing channel access procedures. Specifically, aspects of the disclosure describe techniques for defining one or more directional beams as a narrow beam, where the relative narrowness of the beam may be determined in the context of interference (e.g., as opposed to being defined from a geometric perspective). For example, a particular beam may be determined to be a narrow beam, and therefore associated with communications in shared radio frequency spectrum bands without channel access procedures, based on one or more metrics and a number of spatial streams associated with the beam. A device may use such narrow beams for communications without channel access procedures in shared radio frequency spectrum bands.
