The TerrAdapt bit, released by Baker Hughes in an effort to help operators address various drilling dysfunctions, uses self-adjusting depth-of-cut control elements. The bit also changes its aggressiveness based on the formation through which it is drilling, to mitigate vibrations, stick-slip, and impact loading.

The tiny, implantable drug-delivery pump for type 2 diabetes, being developed by Intarcia Therapeutics, works by releasing a drug into a patient's body over time, overcoming the problems that some patients have complying with a schedule of injections. Researchers now are looking to broaden their focus to HIV as well.

Engineers at the University of Colorado Boulder have developed a bio-manufacturing process to turn brewery wastewater into naturally derived lithium-ion battery electrodes. The researchers opine that applying the process on a large scale will dramatically reduce municipal wastewater costs for breweries while creating a cost-effective process for making advanced battery components. A new Boulder-based company, Emergy, seeks to commercialize the patented process, which is detailed in this video.

This story out of the Nanyang Technological University in Singapore details the development of a new type of nanofilter for wastewater treatment. It allows for combining of the typically separate ultra-filtration and reverse osmosis (RO) processes. The secret ingredient to the new nanofilter, as noted in an article on Engineering360: a hollow fiber membrane that, among other attributes, requires only 2 bars of water pressure yet produces water nearly as pure as that resulting from RO. The pressure conventionally required is 10 bars or more. The membrane promises to dramatically reduce the amount of energy needed to power the pumps used in the process.

Dubbed the largest in the western hemisphere, the recently commissioned Claude "Bud" Lewis Carlsbad Desalination Plant in California takes in 100 million gal/day of cooling water from the nearby Encina Power Plant, and produces some 50 million gal/day of potable water. Its pump station features eight multistage vertical turbine pumps; also at work here are three large, vertical seawater-intake pumps. As reported by IHS Engineering360, the high-speed electrical pumps are acoustically attenuated to meet noise ordinances. The intake pumps are constructed from super-duplex stainless steel; the turbine pumps - double-suction, twin-volute models - are constructed from Type 316L stainless steel.
