Worcester Polytechnic Institute | Date: 2016-08-12

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.

A dry electrode manufacturing process employed for low cost battery through a dry mixing and formation process. A thermal activation renders the dry fabricated electrode comparable to conventional slurry casted electrodes. The dry electrode mixture results from a combination of a plurality of types of constituent particles, including at least an active charge material and a binder, and typically a conductive material such as carbon. The process heats the deposited mixture to a moderate temperature for activating the binder for adhering the mixture to the substrate; and compresses the deposited mixture to a thickness for achieving an electrical sufficiency of the compressed, deposited mixture as a charge material in a battery.

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.

Patent
Worcester Polytechnic Institute | Date: 2016-11-22

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.

A molecular thermoelectric (M-TE) lipid layer includes a lipid bilayer or monolayer and a dopant, and in particular, the dopant can be an n-type dopant, a p-type dopant, or a hybrid thereof. The dopant can be selected from modified biological molecules, such as lipid, transmembrane protein and oligonucleotides. A molecular thermoelectric (M-TE) lipid device can incorporate the molecular thermoelectric (M-TE) lipid layer.

Embodiments of the innovation relate to, in an access controller, a method for providing access to a network resource. The method includes receiving, by the access controller, a network access request and user interaction information associated with the network access request from the client device, the user access information received with the network access request from the client device. The method includes comparing, by the access controller, the user interaction information with a policy corresponding to the user interaction information. The method includes providing communication, by the access controller, between the client device and the network resource associated with the network access request in response to detecting an association between the user interaction information and the policy.

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.
