Systems, devices, and methods employing electrochemical processing of hydrofluoroolefins
Hydrofluoroolefin (HFO) fluid can be transported through an electrochemical device, which has a proton exchange membrane (PEM) disposed between a pair of gas-permeable electrodes that include respective catalysts. At an inlet side, the catalyst facilitates reaction of HFO with hydrogen carrier gas. The resulting cation is transported across PEM in the presence of an electric field applied to the electrodes. At an outlet side, the catalyst of the opposing electrode facilitates dissociation of the cation back into HFO and hydrogen. In some embodiments, the transported HFO has a higher pressure than that before the electrochemical device. In some embodiments, the electrochemical device can be operated in reverse to expand HFO fluid and/or to recapture power. The electrochemical device can thus be used as a compressor or expander for vapor-phase HFO or as a pump or expander for liquid-phase HFO, for example, in power generation or heating/cooling cycles. |

Methods of lowering the error rate of massively parallel DNA sequencing using duplex consensus sequencing
Next Generation DNA sequencing promises to revolutionize clinical medicine and basic research. However, while this technology has the capacity to generate hundreds of billions of nucleotides of DNA sequence in a single experiment, the error rate of approximately 1% results in hundreds of millions of sequencing mistakes. These scattered errors can be tolerated in some applications but become extremely problematic when “deep sequencing” genetically heterogeneous mixtures, such as tumors or mixed microbial populations. To overcome limitations in sequencing accuracy, a method Duplex Consensus Sequencing (DCS) is provided. This approach greatly reduces errors by independently tagging and sequencing each of the two strands of a DNA duplex. As the two strands are complementary, true mutations are found at the same position in both strands. In contrast, PCR or sequencing errors will result in errors in only one strand. This method uniquely capitalizes on the redundant information stored in double-stranded DNA, thus overcoming technical limitations of prior methods utilizing data from only one of the two strands. |

The dispersant includes a polymer having a carboxyl group and having a weight average molecular weight of 5,000 or less, and permeates through the clarification equipment. The polymer having a carboxyl group and having a weight average molecular weight of 5,000 or less permeates through the clarification equipment, and performs as a scale dispersing agent for the RO membrane, preventing precipitation of scale. Since the polymer intrinsically has an anticorrosion effect, it becomes unnecessary to add a phosphoric acid compound to the cooling water system as an anticorrosion agent, or the required amount of the compound to be added can be reduced. |

Flame-retardant antibacterial composite polypropylene filter material and preparation method thereof
A flame-retardant antibacterial composite polypropylene filter material and a preparation method thereof are disclosed. The filter material includes the following components in weight percent: 70-90 wt % of isotactic polypropylene, 3-10 wt % of a functional negative ion-releasing material, 3-10 wt % of a nano-antibacterial agent, 2-5 wt % of graphene oxide, 0.5-5 wt % of a flame retardant and 1-3 wt % of a dispersant. The filter material of the present invention can be prepared into network, fabric and other forms by the melt-blending extrusion, which can be applied for air pollutant removal in different environments. The functional negative ion-releasing material is a piezoelectric material, which can spontaneously produce negative oxygen ions, without consumption of energy or producing secondary pollution such as ozone. The released negative oxygen ions interact with positively charged particles in the air for settling, so as to quickly remove the particles. |

Fuel filter
Embodiments for a fuel filter are provided. In one example, a diesel fuel filter comprises a header having an inlet port, an outlet port, a recirculation inlet port, and a recirculation outlet port; and a filter body made having different material than the header, the filter body coupled with the header and housing a filter membrane. In this way, electrostatic discharge may be reduced. |
