Abstract: Methods for analyzing DNA-containing samples are provided. The methods can comprise isolating a single genomic equivalent of DNA from the DNA-containing sample to provide a single isolated DNA molecule. The single isolated DNA molecule can be subjected to amplification conditions in the presence of one or more sets of unique molecularly tagged primers to provide one or more amplicons. Any spurious allelic sequences generated during the amplification process are tagged with an identical molecular tag. The methods can also include a step of determining the sequence of the one or more amplicons, in which the majority sequence for each code is selected as the sequence of the single original encapsulated target. The DNA-containing sample can be a forensic sample (e.g., mixed contributor sample), a fetal genetic screening sample, or a biological cell.

Abstract: A hydrogen canister fuel cell battery including a base having at least one hydrogen distribution channel communicating with a hydrogen canister for passage of hydrogen to a fuel cell on the base. An air supply is disposed in front of the fuel cell for sending air into the fuel cell, so that oxygen and hydrogen may react electrochemically in the fuel cell to generate electricity. The present invention also provides an arrangement that utilizes fuel cells to have a larger area of contact with the ambient air so as to eliminate use of fans and starting power devices and thus achieve a compact hydrogen canister fuel cell battery for use in products such as notebook computers and cellular phones.

Abstract: An electrode membrane assembly structure comprises a substrate, two active catalytic layers, each active catalytic layer consisting of micro-particle metal layer(s) and porous conducting layer(s) arranged alternately, and a solid polymer membrane layer being sandwiched in said two active catalytic layers and having protonic conductivity. And a method for manufacturing an electrode membrane assembly comprises the steps of forming an active catalytic layer comprising micro-particle metal layers and porous conducting layers on a substrate by plasma sputtering deposition and chemical vapor deposition (CVD), respectively; then forming a solid polymer membrane layer having protonic conductivity on said active catalytic layer by chemical vapor deposition; and followed by further forming another active catalytic layer on said solid polymer membrane layer, all under the condition of vacuum environment, to obtain the electrode membrane assembly.
