The ulrathin foil with a thickness of 200 nm provided by Nano Membrane was investigated. However, it was found not to be strong enough physically for confining hydrogen in the vacuum. A MICTRON foil(TORAY) with the thickness of 3.6μm was tested, which was the thinnest nonmetallic foil commercially available. The mictron window bulged out at the certain values of the inner pressure ; however, it withstood pressure difference up to 2 atmosphere. Below the temperature of 18K, hydrogen at the pressure of 423 hPa was confined to the cell and fully liquefied successfully. The physical strength is almost equivalent to 12μm luminor foil, whose young's modulus is 4GPa.

研究了由纳米膜提供的厚度为200 nm的超薄薄膜。然而，人们发现它的物理强度不足以将氢限制在真空中。测试了一种厚度为3.6MICTRONμm的微金属箔(TORAY)，这是市面上可获得的最薄的非金属箔。在一定的内压力值下，微中子窗口会鼓起，但它可以承受2个大气压的压差。在18K以下，氢气在423百帕的压力下被限制在电池内，并成功地完全液化。其物理强度几乎相当于12μm发光箔，其杨氏模数为4 Gpa。
