Abstract: A solar cell including a quantum dot, an electron conductor, and a rigid bridge molecule disposed between the quantum dot and the electron conductor. The rigid bridge molecule may include a first anchor group that bonds to the quantum dot and a second anchor group that bonds to the electron conductor. The solar cell may include a hole conductor that is configured to reduce the quantum dot once the quantum dot absorbs a photon and ejects an electron through the rigid bridge molecule and into the electron conductor.

Abstract: A method of creating a metal nanoparticle hydrogel biological array comprises placing a plurality of metal nanoparticles in each of a plurality of wells on a substrate, and placing a biomolecular probe material into the plurality of wells. Hydrogel precursors are placed in each of the plurality of wells; and are polymerized to form hydrogel such that the metal nanoparticles are embedded in the hydrogel.

Abstract: A fuel for splitting water into hydrogen and an oxide component comprises a substantially solid pellet formed from a solid-like mixture of a solid-state source material capable of oxidizing in water to form hydrogen and a passivation surface layer of the oxide component, and a passivation preventing agent that is substantially inert to water in an effective amount to prevent passivation of the solid-state material during oxidation. The pellets may be introduced into water or other suitable oxidizer in a controlled rate to control the rate of reaction of the source material with the oxidizer, and thereby control the rate of formation of hydrogen. Methods are described for producing the solid-like mixture in varying weight percent of source material to passivation preventing agent.

Abstract: A method for demodulating a focusing error signal in an optical disc system, comprising the steps of (A) generating a beam strength signal and the focusing error signal, (B) sampling the beam strength signal and the focusing error signal at an appropriate sampling rate, (C) removing a static offset from the beam strength signal and the focusing error signal, (D) calibrating a peak-to-peak value of the beam strength signal and the focusing error signal, and (E) determining an appropriate phase to (i) demodulate the focusing error signal and (ii) calculate a vertical position of a lens in relation to a disc.

Abstract: A part recycle device of a document file includes two spaced first through holes formed in a clamping member, two spaced second through holes formed in a side wall of an outer plate, two screw members, a press plate, and two nuts. Each of the two screw members extends through one of the two spaced first through holes and one of the two spaced second through holes. The press plate has a first end face formed with two spaced third through holes, and a second end face provided with two spaced protruding rings each formed with a polygonal recess aligning with one of the two spaced third through holes. Each of the two nuts is received in the polygonal recess of one of the two spaced protruding rings of the press plate, and may be engaged with one of the two screw members.

Abstract: A sucker-type suspension structure includes a sucker, a sucker cover, and a suspension hook. The sucker has an outer wall provided with a pull plate which has a distal end formed with a rod passage hole for passage of a pivot rod. The sucker cover is mounted on the outer wall of the sucker, and has a center formed with a plate passage hole for passage of the pull plate of the sucker. The suspension hook has a top formed with a U-shaped plate receiving space for receiving the pull plate of the sucker. The plate receiving space of the suspension hook has two side walls each having a first section formed with a rod passage hole for passage of the pivot rod, and a second section formed with a cover press lug rested on an outer wall of the sucker cover.
