Electrochemical Method for Removing Pollutants from Water

This method removes even extremely low levels of organic contaminants such as pesticides, chemical waste products, and pharmaceuticals.

When removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy- and chemical-intensive. A new method was developed that could provide a selective alternative for removing even extremely low levels of unwanted compounds. The method relies on an electrochemical process to selectively remove organic contaminants such as pesticides, chemical waste products, and pharmaceuticals, even when these are present in small, yet dangerous concentrations. The approach also addresses key limitations of conventional electrochemical separation methods such as acidity fluctuations and losses in performance that can happen as a result of competing surface reactions.

Structural Health Monitoring System/Method Using Electroactive Polymer Fibers

Potential applications include impact, delamination, and fatigue crack sensing.

NASA's Langley Research Center has developed a novel polymer material that can be utilized as a real-time structural health monitoring sensor. The material is electroactive and generates a signal in response to a mechanical force. The material is also highly elastic, which allows for a large range of measurable strain levels, and is highly durable.

Product of the Month: August 2017

Harwin, Salem, NH, announced the SYCAMORE surface-mount socket that provides pin retention and durability for high-volume applications manufactured using automated systems. The capacitor's design features three points of contact, providing continuity and robustness. Key markets include gas detection systems, metering systems, and other applications that require modules and devices such as field-replaceable parts or temperature-sensitive components to be mounted to a printed circuit board. The single-part SMT socket design features a profile of 0.3 mm above the PCB. Available in top and bottom entry versions, it accepts 1.0 or 1.50 mm-diameter pins, and is open-ended for unlimited mating pin depth. It is manufactured from beryllium copper, and contacts are gold-plated to ensure high conductivity over a temperature range of -50 to +125 °C.

Algorithm Enables Five-Dimensional Imaging in Living Organisms

This technique is faster, less expensive, and more accurate than current methods, and works with cellphone images.

Researchers use fluorescent imaging to locate proteins and other molecules in cells and tissues by tagging the molecules with dyes that glow under certain kinds of light — the same principle behind “black light” images. Fluorescent imaging can help scientists and researchers understand which molecules are produced in large amounts in cancer or other diseases. This information may be useful in diagnosis or in identifying possible targets for therapeutic drugs.

Do you see augmented reality as a way of improving design processes?

A report last week concluded that the augmented reality (AR) market is expected to grow from $2.39 billion in 2016 to $61.39 billion by 2023. The research from the Hadapsar, India-based analyst firm MarketsandMarkets cites increasing demand for AR devices and applications in healthcare, retail, and e-commerce sectors.

AR plays a potential role for design engineers looking to model a product directly into an environment. What do you think? Do you see augmented reality as a way of improving design processes?
