Worcester Polytechnic Institute is a private research university in Worcester, Massachusetts, focusing on the instruction and research of technical arts and applied science.Founded in 1865 in Worcester, WPI was one of the United States' first engineering and technology universities and now has 14 academic departments with over 50 undergraduate and graduate degree programs in science, engineering, technology, management, the social science, and the humanities and arts, leading to bachelor's, master's and PhD degrees. WPI's faculty works with students in a number of research areas, including biotechnology, fuel cells, information security, materials processing, and nanotechnology. Wikipedia.

A noncontact temperature sensing device receives radiative emissions from a sensed object to measure radiant heat flux and computes a temperature using multiple photodiode sensors, or elements, each sensitive to a different bandwidth of near IR light. The device samples a fluctuating heat source such as a flame or explosion at a fast sampling frequency, and compares corresponding or simultaneous readings in each bandwidth for computing a ratio of the respective bands and determining a temperature via ratio pyrometry. Multiple sensors of adjacent bands each receive corresponding readings of near IR emissions, perform fast, concurrent sampling to mitigate inconsistencies of heat source fluctuations, and compute a temperature based on a ratio between the sampled readings of the different bands. Near IR detection allows common and inexpensive photodiodes to be employed, and the photoelectric rather than thermoelectric sensing allows faster sampling and at a greater distance from the sensed heat source.

An electrohydrodynamic (EHD) pump increases refrigerant flow rate and the resulting pressure in a vapor compression based cooling system for permitting reduced compressor sizes and power demands. The EHD pump disposes electrodes in a liquid path of the refrigerant flow, and increases fluid flow and resulting pressure by an induced liquid flow between a pair of asymmetric electrodes. Voltage applied to these electrodes results in a conduction pumping mechanism associated with heterocharge layers in the vicinity of the electrodes based on disassociation of a neutral electrolyte species in the refrigerant fluid and recombination of the generated ions. The induced flow draws the liquid due to a net fluid flow toward one of the electrodes based on the asymmetry of the electrode pair. Electrodes are disposed on an inner surface of a refrigerant vessel, in communication with an annular liquid film that forms around the inner circumference in two-phase fluid systems.

Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

Compositions and methods for coating medical devices are provided. A coating composition may comprise a tether covalently attached to an anti-microbial peptide, the tether having sufficient length to permit the anti-microbial peptide to at least partially penetrate a membrane of a bacteria, upon contact of the anti-microbial peptide with the bacteria.

A self-healing coating for reinforcing steel embedded in concrete includes emulsion derived microcapsules having a healing agent and adapted for dispersion through a liquid coating medium for application on a structural steel surface to form a coating for corrosion prevention. The microcapsule particles are dispersed in the coating medium for being disposed on the surface and are configured to rupture and release the healing agent onto the surface in response to a compromise of the coating, such as being dropped or dragged on a construction site. The self-healing agent, such as Tung oil, complements the protective properties of the coating medium by flowing into regions where the coating medium has been scraped off, flaked off, or otherwise undergone compromise. Alternatively, post-installation corrosive influences, such as rust and oxidation, can also cause rupture of the particles to abate corrosion in the concrete-encased steel members.

Massive data collection by businesses and governments calls into question traditional methods for protecting privacy, underpinned by two core principles: (i) notice, that there should be no data collection system whose existence is secret, and (ii) consent, that data collected for one purpose not be used for another without user permission. But notice, designated as a fundamental privacy principle in a different era, makes little sense in situations where collection consists of lots and lots of small amounts of information, whereas consent is no longer realistic, given the complexity and number of decisions that must be made. Thus, efforts to protect privacy by controlling use of data are gaining more attention. I discuss relevant technology, policy, and law, as well as some examples that can illuminate the way.
