Abstract: A binder-free, self-supporting electrode including an electrochemically active material in the absence of a binder and a current collector is claimed. The electrochemically active material is a self-supporting transition metal oxide. A method of regenerating the electrode to restore capacity of the electrode is also claimed.

Abstract: Disclosed are RNA constructs which function to activate or inactivate a biological process, e.g., may be designed for attachment to a polypeptide coding region. Such RNA constructs modulate translation of a polypeptide from the coding region in response to the presence of a target polynucleotide in an expression environment. Such RNA constructs include a weakened stem-loop structure which, when bound to the target polynucleotide, assumes stem-loop secondary structure and associates with an RNA binding protein. Association with the RNA binding protein modulates translation of the polypeptide coding region. Such RNA constructs also have three-way junction joining regions 3? and 5? of the stem-loop structure.

Abstract: A method of stabilizing a fluorine-containing acid amplifier.

Abstract: Reliable, fast and inexpensive breath gas detector systems for medical diagnostics, including personal, handheld monitoring devices for a variety of diseases and conditions, including, for example, asthma, diabetes, blood cholesterol, and lung cancer. A sensor device (100) for detecting gases includes a sensing element (109) having an electrical resistance that changes in the presence of a target gas; a readout circuit, electrically coupled to the sensing element due to the presence of the target gas and converts the measurement to a digital signal; and a feedback loop (203) from a digital unit (205) to the readout circuit to compensate for variations in a baseline resistance of the sensing element.

Abstract: Methods of reducing NO.sub.x to nitrogen without using a reducing gas. The NO.sub.x is absorbed in a heteropoly compound to concentrate it and then heated to reverse the fixation reaction(s) and decompose the NO.sub.x into nitrogen.
