A medical device (e.g., an analyte sensor) that may be implanted within a living animal (e.g., a human) and may be used to measure an analyte (e.g., glucose or oxygen) in a medium (e.g., interstitial fluid, blood, or intraperitoneal fluid) within the animal. The medical device may include a polymer covering at least a portion of a surface of the medical device and a plurality of reactive oxygen species (ROS) scavenger molecules covalently linked to the polymer (e.g., to reduce degradation of an analyte indicator including the polymer).

This method is for improving the combustion resistance of a working fluid containing a refrigerator oil and a refrigerant in a refrigerator filled with the working fluid, wherein the refrigerator oil contains 0.1 mass% to 10 mass% of an acid scavenger with respect to the total amount of refrigerator oil.

According to the biological purification device, a generator is connected with a storage battery, and the storage battery is connected with a driving circuit; one end of the drainage pipe is connected with the water pump, the other end of the drainage pipe is arranged above the water tank, the water tank is arranged on the upper right portion of the shell, a drainage plate of the drainage pipe faces the inclined filter screen, the right end of the inclined filter screen is hinged to the right side of the culture pond, the left side of the inclined filter screen is arranged at the upper end of a middle inclined step, and the left end of the inclined filter screen is arranged on the upper right portion of the decomposition pond; the filter plate is arranged in a middle hole of a middle inclined step for separating the shell into the decomposition tank and the culture tank and is communicated with the decomposition tank and the culture tank; the gas-lift filter is arranged at the bottom of the culture pond and connected with the reversing valve through a left gas pipe, a right gas pipe and a middle gas pipe, and the reversing valve is connected with the gas pump through a gas supply pipe. The power generator is uniform in output electric quantity, the gas lift filter can accurately adjust the PH value of a water body, and secondary pollution is avoided; the organic solid waste treatment speed of loaches and scavengers in the decomposition tank is far higher than that of plants, microorganisms, reeds and water hyacinth, inorganic salt is filtered in a three-dimensional mode, and the space utilization rate is high.

A treatment composition includes a scavenger, an amine, and optionally a booster amine. A treatment composition may be contacted with an H2S rich stream by direct addition of the composition to the H2S rich stream, or by bubbling the H2S rich stream through the composition. The H2S rich stream may be e.g. a produced gas, a biogas, a crude oil, or a produced water. The treated streams have a reduced amount of H2S (and / or another sulfhydryl compound) therein, when compared to the amount of H2S in the stream prior to the treatment. The compositions and methods of treating are characterized by a substantial absence of, or reduction in the amount of precipitate formed thereby, when compared to methods and compositions of the prior art.

The current invention pertains to a use of a scavenger in method or protocol for treatment of a plant cell with a mutagen, optionally in a method for random mutagenesis, mutagenized plants obtained using said method or protocol, and a composition or kit for use in said method or protocol.

This invention discloses a carbon dioxide eliminator for drilling fluids, its preparation method, and its application, comprising the following steps: S1, grinding walnut shells into powder; S2, hydrophilically modifying the walnut shell powder to obtain modified walnut shell powder; S3, adding the modified walnut shell powder to water, stirring, and adding calcium chloride and gluconic acid; S4, filtering and drying the mixture from step S3 to obtain a solid powder; S5, granulating the solid powder and drying it to obtain solid particles; S6, coating the surface of the solid particles obtained in step S5 to obtain the carbon dioxide eliminator for drilling fluids. This invention utilizes the porous structure of walnut shells as a support, enabling the storage of calcium ions, the main component for eliminating carbon dioxide, within it, thereby achieving a slow and continuous release of calcium ions in the drilling fluid; simultaneously, the hydrophilically modified walnut shell powder can disperse rapidly in water, increasing the release rate of calcium ions and thus improving the efficiency of carbon dioxide elimination.

The application discloses a multi-scale sucker of a biomimetic scavenger fish for non-destructive adsorption fixation of organ tissues. The sucker comprises a lip disc with a stiffness gradient characteristic, a pre-valve cavity and a post-valve cavity, the lip disc is provided with a biomimetic papilla structure and a mucus secretion flow channel, and a side wall of the sucker is provided with a negative pressure through hole. Through the multi-scale biomimetic mechanism of coupling negative pressure adsorption, chemical adhesion and capillary force adsorption, the sucker can realize high-strength, high-reliability and non-destructive adsorption fixation on the surface of wet and soft organ tissues, can be used for traction and stabilization of tissues in minimally invasive surgery, and can effectively expand and maintain the exposure of an operation field.
