Various embodiments provide devices, methods, and systems for high throughput biomolecule detection using transducer arrays. In one embodiment, a transducer array made up of transducer elements may be used to detect byproducts from chemical reactions that involve redox genic tags. Each transducer element may include at least a reaction chamber and a fingerprinting region, configured to flow a fluid from the reaction chamber through the fingerprinting region. The reaction chamber can include a molecule attachment region and the fingerprinting region can include at least one set of electrodes separated by a nanogap for conducting redox cycling reactions. In embodiments, by flowing the chamber content obtained from a reaction of a latent redox tagged probe molecule, a catalyst, and a target molecule in the reaction chamber through the fingerprinting region, the redox cycling reactions can be detected to identify redox-tagged biomolecules.

The present invention provides a reactor and gasification process for the continuous controlled production of hydrogen (H2) and a by-product synthesis gas (mixture of CO+H2+CO2), such a process called a hydrogen priority poly-generation process (HPPP). The reactor uses a circulating molten iron process, which is capable of gasifying a variety of carbonaceous materials including low rank coals and biomass. The process employs an iron steam oxidation-reduction cycle in a multi-chamber reactor including a multi-vessel reactor system, where in one compartment or vessel hydrogen is produced by steam oxidation of molten iron; and in a second compartment or vessel the iron is regenerated by carbon reduction of molten iron oxide thereby producing a by-product synthesis gas (CO+H2+CO2), and excess heat which can be used to produce steam, and in a third step the iron is purified before being returned to the steam oxidation step in the process. An embodiment of this process uses low rank coals having high ash levels in a reactor, which is designed to continuously extract ash from the molten iron bath. A second embodiment uses low ash carbon materials such as highly beneficiated coals in a simpler process that produces pure streams of hydrogen and CO.

A discharge-lamp lighting device is provided which decreases arc jumps, suppresses the fluctuation in brightness of the lamp, and prolongs a life of the lamp, by positively accelerating growth of spots even when an inexpensive, small and highly efficient lamp is used. A discharge-lamp controlling portion (101) sets frequencies of drive-controlling signals (A and B) for drive-controlling a commutator (109) within a predetermined frequency range so that spots formed by arc discharge on electrodes composing a high-pressure discharge lamp grow through a cycle of oxidation-reduction of a metal composing the electrodes, and superimposes a triangular wave signal generated on the basis of the drive-controlling signals onto a current-controlling signal (F) over an entire period of the drive-controlling signals so as to make a peak value of the triangular wave constant, thereby adjusting the waveform of current flowing in the high-pressure discharge lamp.
