Abstract: Ultrasonic through metal communication systems are an effective solution for transmitting data across a metal barrier when the structural integrity of the barrier cannot be compromised by physically penetrating it. Substantial improvements in through metal communication systems have been made in recent years, enabling high speed communications of up to 15 Mbps, as well as power transmission up to 30 W across flat walls. A system is described that allows for ultrasonic through metal communication across the wall of a steel tube. Primary challenges of 1) transducer contact, 2) curvature effect on echoes, and 3) alignment are analyzed and addressed through the use of radial mode piezoelectric transducers, transducer “horns”, and Electromagnetic Acoustic Transducers (EMATs). The resulting system shows no significant loss due to changes in alignment, allows for the use of either piezoelectric transducers or EMATs externally, and achieves max data rates of approximately 600 kbps without echo equalization.

Abstract: An aqueous approach to synthesize capped SnS quantum dots (QDs) followed by optional capping molecule extension by attaching one or more extending molecules to the capping molecule via peptide bond formation at elevated temperature. The capped SnS QDs may have a capping molecule:Sn:S molar ratio of 16:3:1 to 16:12:1. A suspension of SnS QDs was heat-treated at 200° C. for 0.5-4 hrs. The obtained SnS QDs showed an NIR emission peak at 820-835 nm with an excitation wavelength at 690 nm. The as synthesized SnS QDs were found to have high positive zeta potential of ˜30 mV and thus were toxic to cells. By neutralizing the SnS QDs the cytotoxicity was reduced to an accepted level. The heat-treatment step can be obviated by adding a glycerol solution containing S2? anions and capping molecule to a glycerol solution of Sn2+ ions.
