Bioplastic Made from Shrimp Shells Breaks Down in Compost

Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering have introduced a new bioplastic isolated from shrimp shells. It’s made from chitosan, a form of chitin — the second-most abundant organic material on Earth. Chitin, a tough polysaccharide, is the main ingredient in the hardy shells of crustaceans, the armorlike cuticles of insects, and even the flexible wings of butterflies.

DBD Device Offers Transdermal Medicine Delivery

DBD Innovations Iontophoresis is a well-researched technique for delivering medicines and cosmetic agents through the skin. Current techniques, however, are inefficient, and existing devices are often expensive, bulky, and awkward. A Dielectric Barrier Discharge Iontophoresis (DBDI) solution enhances the efficacy of existing remedies by applying a small electronic device to the treated area.

Dispensing Closure Technology Seals and Separates Ingredients

StarOne Group The Drop-Top™, a container closure and delivery system, features an internal, multi-cavity design that stores up to three separate doses of ingredients, including liquids, powders, gases, granules, or tablets. The dispensing closure technology increases the shelf life of products that are not stable in oxygen or aqueous solutions, and stores highly sensitive products that cannot have any contact with the environment or specific ingredients.

Extended-Wear Patches for Skin Hydration

Moisturizers and active ingredients must be held against human skin in a patch format. To enhance uptake, a new material needs to be designed for extended wear from 1-10 hours. Comfort and physical flexibility are two chief requirements. Ideally, the patch will also reduce the appearance of wrinkles. Proposed materials must cover large or small areas of skin, and conform to the shapes of those areas. Possible solution areas include natural and synthetic yarns or materials, wovens and nonwovens, and extruded or film materials. The materials may be held against the skin by a suitable adhesive.

Monitoring Battery Health in Solar-Charged Systems

In solar-powered, battery-run systems, each unit’s battery stores electricity generated by the solar panel during the day and provides electricity to a load when required. The systems currently are networked, but no method is in place to determine or report battery health. A client seeks ways to pre-emptively warn the customer when a battery is about to reach the end of its useful life. Possible solution areas include algorithmic technologies based on time-varying voltage, current, and other metrics during charge/discharge cycles.

Product of the Month: July 2014

The iQ-200™ instrument from Advanced Thermal Solutions, Norwood, MA, measures the temperatures of solid materials and surrounding air, while also tracking air velocity and air pressure. Measurements are taken simultaneously at multiple points to profile heat sinks, PCBs, and card racks for testing and characterization. The instrument simultaneously captures thermal data from up to 12 thermocouples that can be J, K, T, and E types. Surface temperature data is recorded from -40 to 750 °C. At the same time, air temperature is measured via 16 hot wire anemometer ports using single-sensor technology; there is no need to change sensors when measuring different velocity ranges. The standard range for air velocity measurement is 0-6 m/s; for custom calibrations, the range is from 0 to 50 m/s. Four additional ports support differential or absolute pressure transducers to capture pressure drop data along circuit cards, assemblies, and orifice plates. Pressure measurements are taken from 0 to 1,034 Pa (0 to 0.15 psi).
