摘要： A method for forming mesophase pitch can include applying a stimulus to a first amount of coal tar to form a first amount of mesophase pitch. The stimulus can include one or more of an electromagnetic field (“EMF”) or a magnetic field. The method can further include evaluating a characteristic of the first amount of mesophase pitch, changing a parameter of the stimulus in response to evaluating the characteristic of the first amount of mesophase pitch, and applying the stimulus exhibiting the changed parameters to a second amount of coal tar to form mesophase pitch.

摘要： A method of forming high molecular weight (“HMW”) coal tar can include combining supercritical carbon dioxide (sCO2) and an amount of coal tar, and fractionating the amount of coal tar to form the HMW coal tar. The method can further include forming the amount of coal tar from coal. Forming the amount of coal tar from coal can include extracting the coal tar from an amount of coal using sCO2.

摘要： A system for analyzing biological specimens by spectral imaging includes a biosensor comprising at least one graphene layer on a substrate and a memory in communication with a processor. The biosensor is configured to acquire a biological specimen sample. The memory and the processor are configured to conduct Raman spectroscopy to obtain spectral data for the sample, transmit the spectral data to a hub for direct or indirect transmission to one or more servers, perform multivariate analysis on the spectral data, and deliver a report based on the multivariate analysis of the spectral data.

摘要： An example method includes providing coal and extracting the graphene from the coal. The graphene may be extracted using any suitable technique, such as the Hummers method, a modified Hummers method, or exfoliation of graphite. The graphene may include impurities or other electrical properties that depend at least partially on the composition of the coal. The method may further include forming a life science device from the graphene. The life science device may include, for example, a biosensor or a drug delivery system.

摘要： A method and apparatus are provided for processing hydrocarbon coal slurry feeds. The method and apparatus enhance the conversion of the coal feeds into useful conversion products, such as high melting and high carbon containing pitch products. In particular, the present techniques utilize a specially designed “self-cleaning” and “wall-catalyzed” preheater-reactor systems.

摘要： Systems and methods of processing coal to form mesophase pitch include performing a low-severity direct coal liquefaction (LSDCL) process on a coal feedstock to produce a coal tar pitch therefrom. The systems and methods can include contacting coal directly with a catalyst in the presence of a solvent, pressurizing the coal in direct contact with the catalyst in the presence of the solvent to a predetermined pressure of about 1000 psia or less, heating the coal in direct contact with the catalyst in the presence of the solvent to a predetermined temperature of about 380° C. or less, and liquefying the coal to form a coal tar pitch. The coal tar pitch can be thermally treated to a liquid crystal phase exhibiting anisotropic spheres of mesophase and spun to form carbon fibers.
