    摘要: A method and apparatus for locally raising the temperature of a material to facilitate chemical reactions or processes related to growth or removal of the material, utilizes an electrode to apply, in the presence of a growth or removal medium, a controlled succession of thermal spikes or shockwaves (6) of varying energy, on the scale of a few nanometers to several hundred micrometers. The duration of the thermal spikes or shockwaves ranges from a few picoseconds to several hundred nanoseconds. The medium may be a cryogenic liquid. Other growth media, including liquids, solids, gases in critical or non-critical state, and mixtures of liquids/solids, solids/gases, and liquids/gases, may also be employed. The electrode may be an electrode emitter tip (1) with an anode (2) above workpiece (4) on platform (3) in the medium. Circuit (5) includes power source (7) with switch (8) controlling voltage pulse duration applied across tip and anode to produce shockwaves.

    摘要: The present invention provides a method for manufacturing an aerogel blanket, wherein a surface modification process is performed under acid conditions while using a non-toxic catalyst, so that a solvent substitution process or a washing process may be omitted to simplify the manufacturing process, and the collapse of a gel structure due to shrinkage is prevented and the efficiency of surface modification is high even when atmospheric pressure drying is performed, so that an aerogel having excellent thermal conductivity and degree of hydrophobicity may be manufactured, and provides an aerogel blanket manufactured by the method, thereby having low thermal conductivity and a low moisture impregnation rate since a hydrophobic group is uniformly formed inside a substrate.
