Abstract Superior thermal insulating and fire-retardant ceramic membranes are urgently demanded in the aerospace, construction and chemical engineering industries. However, the generic characteristics of ceramic membranes, such as brittleness, structural collapse and crystallization-induced pulverization behavior, present a great plague to their practical applications. Herein, we report a highly flexible, mechanically stable, fire retardant and high-temperature-resistant ceramic membrane based on the interlocked Si₃N₄ nanowires formed by the precursor pyrolysis method. The Si₃N₄ nanowires membrane (SNM) has excellent high temperature resistance under alcohol lamp and butane spray lance. The thermal insulation with a thermal conductivity as low as 0.056… More >

Abstract Ultra-deep reservoirs play an important role at present in fossil energy exploitation. Due to the related high temperature, high pressure, and high formation fracture pressure, however, methods for oil well stimulation do not produce satisfactory results when conventional fracturing fluids with a low pumping rate are used. In response to the above problem, a fracturing fluid with a density of 1.2~1.4 g/cm was developed by using Potassium formatted, hydroxypropyl guanidine gum and zirconium crosslinking agents. The fracturing fluid was tested and its ability to maintain a viscosity of 100 mPa.s over more than 60 min More >
