Implementations described herein are directed to leveraging odor sensor(s) of client device(s) in responding to user request(s) and/or in generating notification(s). Processor(s) of a given client device can receive a request to identify an odor in an environment of the given client device, process an odor data instance generated by the odor sensor(s) of the given client device, identify the odor based on processing the odor data instance, generate a response that identifies the odor and/or a source of the odor, and cause the response to the request to be rendered via the given client device. Processor(s) of the given client device can additionally, or alternatively, establish baseline odor(s) in the environment and generate a notification when an odor is detected that does not correspond to the baseline odor(s) and/or exclude the baseline odor(s) in generating the response to the request.

A chemical pre-concentrator includes a conduit defining a flow path between two ends and having a heating element disposed within the conduit, such that the heating element has at least one sorbent material deposited directly on at least a portion of a conductive surface of the heating element. Some such heating elements are in the form of electrically conductive strips defining both a plurality of apertures through the strip and a series of undulations spaced along the flow path.

A method and apparatus for determining content of adsorbed gas in a deep shale, and a server, wherein experimental tests are combined with molecular dynamics models. Firstly, tests are performed on a core sample of a target area at various temperatures in a first-class pressure environment with low pressure to obtain shale gas adsorption data of the core sample; next, a first shale molecule dynamics model of the core sample is established, and a fitting adjustment is performed on the first shale molecule dynamics model using the shale gas adsorption data to obtain a second shale molecule dynamics model. Further, the second shale molecular dynamics model is used to obtain, by analogue simulation, shale gas adsorption data of the core sample corresponding to the various temperatures in a second-class pressure environment with high pressure, so as to obtain an accurate and comprehensive adsorption characteristic curve in a full pressure range.

The present invention discloses an apparatus and process for measuring the maximum gas adsorption/desorption capacity of a powdered solid sample, particularly coal/shale, by volumetric method. It is innovative in a way that it can perform adsorption/desorption isotherm measurements for a set of four samples simultaneously, where four separate channel has been fabricated through a single gas injection point. As the natural adsorbent samples may be from different burial depths, the apparatus is capable of carrying out adsorption/desorption measurements simultaneously on four samples at different temperatures corresponding to their depth through a compartmentalized water bath system. Apart from that, the apparatus can measure adsorbed gas capacity up to a very high pressure of 40 MPa replicating the reservoir depth up to 4000 m. Moreover, sample vessels are also able resist 6000 Psi pressure. The apparatus is also enabling to handle the toxic, reactive and highly flammable gases. Mentioning high temperature with an accuracy of 0.1 C. is another unique feature of the present invention. The apparatus finds its application for the gas storage capacity and recoverable reserve estimation for CBM, Shale gas and CO.sub.2 geo-sequestration projects.

A measurement apparatus for hydrogen solubility and competitive dissolution of multi-component gases includes a gas dissolution mechanism, and the gas dissolution mechanism includes a heat-insulated box. A first piston plate and a second piston plate are slidably connected in a dissolution cylinder and a gas cylinder, respectively, a middle part of the first piston plate is connected to a gas transport pipe, and the gas transport pipe can connect upper and lower spaces of the first piston plate. The apparatus can clearly determine partial pressure generated by conversion of the formation water into the water vapor, and maintains preset partial pressure of hydrogen through dynamic adjustment by the second piston plate to eliminate an error caused by the change in a volume of the formation water. The first piston plate isolates a gas from the formation water to prevent the backflow of the formation water during gas replacement and vacuumizing.
