In certain embodiments, a power generator has a rotor, a stator, a bridge rectifier, and one or more capacitors. The stator has one or more inductors that generate phased AC power when the rotor moves relative to the stator. The bridge rectifier, which is connected between the inductors and two output terminals of the power generator, converts the phased AC power into a DC output current at the two output terminals. The capacitors are connected to the inductors to electro-magnetically resonate when the rotor moves relative to the stator to increase peak amplitudes of the phased AC power and thereby increase the level of the DC output current. In certain applications, the increased. DC output current enables the power generator to charge a battery faster and more efficiently.

Polymer compositions for coating of metal surfaces including moieties that interact with a metal atom in the metal surface and optionally containing antifoulant moieties. These polymer compositions provide lubricious coatings for medical devices, anticorrosion coatings for metal components, and antifoulant coatings for marine components such as propellers. The polymer composition is synthesized in a safe manner in which the synthesis components are added to a synthesis vat and there is no need for filtration or removal of waste materials in any step including the consumer use. As such this invention provides an environmentally sound approach to composition synthesis, formulation development, and consumer use.

Waste reduction, including hazardous waste reduction in photoimaging processes can be accomplished by improving diffusional resolution of cationic curable compositions. The addition of fluorinated polymers including fluorinated surfactants provides improved diffusional resolution in cationic and/or radical based photoimaging formulations allowing for image accuracy improvements, and reduced product and process waste quantity and disposal cost. These fluorinated surfactants also allow for increased cure speed, and non-hazardous constituent formulations that result in less wasted material and time.

Method and composition for reducing waste in photo-imaging applications

A composition comprising a cationically-polymerizable compound, an iodonium-based cationic initiator, a sensitizer for said cationic initiator and an antioxidant selected from the group consisting of phenol antioxidants, lactone antioxidants, and combinations of these antioxidants is provided. The addition of this antioxidant to this composition contributes to the reduction of potential run-away reaction when it is exposed in-bulk to actinic radiation.

Solid objects are formed in an imagewise layering process in which components of a dispersion are homogenized to form an alloy. Imagewise exposure of the layers to radiation to form an alloy permits separation of the exposed, homogenized regions from non-exposed, non-homogenized regions. As each layer is formed and imagewise homogenized, contiguous layer regions are bonded together to form a homogenized, three-dimensional object which may be separated from surrounding dispersion.
