Abstract: A screw holder for holding a screw to be driven by a screwdriver. The screw holder may include a longitudinal holder body with first and second ends. A through-hole may be provided from the first to the second end, with the first end having an opening configured to receive a blade and shank of a screwdriver, and the second end having an opening configured to receive the screw. The second end opening may progressively taper towards the first end. The through-hole may be configured to allow the blade of the screwdriver the engage with the head of the screw within the holder body.

Abstract: A breathable waterproof stretchable multi-layer foam construct includes a stretchable closed-cell foam layer having a first face and a second face. A plurality of vents are dispersed across the foam layer, with each vent extending through the foam layer from a first end at the first face to a second end at the second face. A first breathable waterproof stretchable fabric laminate is bonded by adhesive to the foam layer and covering the first end of each vent at the first face. A second breathable waterproof stretchable fabric laminate is bonded by adhesive to the foam layer and covering the second end of each vent at the second face. The breathable waterproof stretchable multi-layer foam construct can be used to fabricate such articles as floatation-assist devices, sports apparel and water immersion suits.

Abstract: An electrode for a lead-acid voltaic cell comprises a high surface area, high porosity 3-dimensional lattice structure wherein the core elements forming the lattice are substantially contiguous. The core elements are coated with one or more corrosion resistant and conductive materials, and solid active materials are coated on the core elements and retained within the matrix. The lattice structure acts as the current collector.

Abstract: A low temperature method for converting poly(hydrocarbyne) into diamond-like carbon is based on removing pendant hydrogen using chemical or electrochemical means.

Abstract: Poly(hydridocarbyne) (PHC) is synthesized by a hybrid, active-metal/electrochemical method by applying a voltage to the electrodes at least one of which is an active-metal, the electrodes being immersed in a trisubstituted halomethane solution. The active-metal electrode and halomethane solution both partake in the electrochemical reaction.
