Abstract: A medical device includes a capacitive micromachined ultrasonic transducer (CMUT) array configured to emit ultrasound to target tissue, and at least one thermoelectric cooler mechanically coupled with the CMUT array and configured to cool non-target tissue heated by the ultrasound. The medical device may be implemented in a catheter together with a solid thermal conductor coupled to the thermoelectric cooler and extending along the catheter, to conduct heat away from the thermoelectric cooler. A catheter or catheter sleeve includes a tubular wall for insertion into a body channel, and at least one thermoelectric cooler coupled to the tubular wall for cooling the body channel wall. A catheter sleeve includes tubular casing for insertion into a body channel and capable of encasing a catheter, and at least one sensor coupled to the tubular casing for sensing one or more properties of the body channel wall, such as temperature and pressure.

Abstract: Herbicidal and pest-control compositions are variously described, including soaps as well as free fatty acids as active ingredients. The disclosed compositions may be constituted in a concentrated form, or the composition may be further diluted for application. Herbicidal compositions of the disclosure may be employed to selectively target unwanted vegetation without a systemic mode of action, and may be used to control a wide variety of unwanted plants, e.g., weeds, woody brush, trees, and/or grasses, in a locus that contains or is susceptible to emergence thereof.

Abstract: A pest-combating composition including sodium lauryl sulfate and one or more of C6-12 fatty acids, preferably lauric and/or capric and/or caprylic acid, soy methyl ester, and 2-undecanone, and methods of combating pests utilizing same, are disclosed. The compositions can include a carrier oil such as silicon oil, soy methyl ester, or a vegetable oil, and can be in the form of an emulsion. The composition may be constituted as a spray composition, an aerosol, a lotion, a paste, or another compositional form. Pests that may be usefully combated with such composition include flying insects, including flies, mosquitoes, and wasps, ants, including arthropods such as fire ants, ticks, fleas, cockroaches, silver fish, thrips, gnats, aphids, Japanese beetles, and agricultural and horticultural arthropods and insects including beetles (potato and bean), flea beetles, fleahoppers, squash bugs, slugs, leaf hoppers, harlequin bugs, milk weed bugs, spiders, mites, lice, rodents, and deer.
