    摘要: A system and process for producing biofuel from spent coffee grounds (SCGs) comprises the steps of performing a first operation comprising the steps of obtaining spent SCGs from a source, washing the SCGs, mixing the washed SCGs with an inorganic acid and heating and stirring the washed SCGs to form a SCG slurry without separating coffee oil, drying the SCG slurry, mixing the dried slurry with a solvent and heating the dried slurry and solvent mixture to create a reaction to produce biofuel and residual grounds, and separating the biofuel from the solvent and the residual grounds. The process further includes the step of using an activation agent and heating the residual grounds and the activation agent to create activated residual grounds. Biochar is also produced without activation and heating de-oiled SCGs at lower temperatures without oxygen.

    摘要: An indoor unit of an air conditioner includes a casing (1) defining a receiving cavity (10), a heat exchanger (2) and a fan (3) disposed in the receiving cavity (10) respectively, and a panel (4) disposed on a bottom of the casing (1). The panel (4) is movable between a close position in which both an air inlet (11) and an air outlet (12) of the receiving cavity (10) are closed and an open position in which both the air inlet (11) and the air outlet (12) are open. In the open position, the panel (4) at least partially separates the air entering via the air inlet (11) from the air exiting via the air outlet (12).

    摘要: Systems and methods that facilitate analysis of superficial tissue based at least in part on a depth-selective fiber optic probe are discussed herein. The depth-selective fiber optic probe can include an illumination fiber for providing light to the superficial tissue, a collection fiber for collected reflected light, a ball lens that couples the fibers, and a protective overtube that houses the ball lens and fibers. The distances between the ball lens and fibers and between the fibers can be optimized based on several factors, such as by minimizing the illumination spot size, maximizing the overlap between the illumination and collection spots, and based on the angle between the illumination and collection beams.

    摘要: Described is a method for preparation of stable fatty alcohol emulsion, wherein, fatty acid esters are introduced into an antifoaming agent emulsion system, and an anionic surfactant is added in the late stage of emulsification process in order to further improve the stability of the emulsion. The anionic surfactant is absorbed to the surface of fatty alcohol particles to make the fatty alcohol emulsion more stable under the action of ionic mutual repulsion. The prepared fatty alcohol emulsion has favorable foam elimination and suppression performance in the paper making procedure, and is stable during storage.
