    摘要： The invention relates to the field of strand displacement, and provides a color image encryption method based on a DNA strand displacement analog circuit. Firstly, a reaction module with a light-emitting group and a quenching group is designed through Visual DSD software, and by utilizing the equivalence of a DNA strand displacement reaction module and an ideal reaction module, an analog circuit formed by the DNA strand displacement reaction module can perform analog on the dynamics characteristics of an ideal reaction network formed by the ideal reaction module, wherein the Rössler chaotic system can be described by the idealized reaction network. Secondly, data generated by the DNA strand displacement analog circuit is converted into a chaotic sequence matched with a plaintext image in size after being extended, and finally, the color image encryption effect is achieved through scrambling and diffusion operations.

    摘要： A carbonaceous particulate material is provided that is characterized by having a reversible volumetric expansion/contraction in fluid media (“VR”) of greater than or equal to (≧)3% between 4,000 psi and 10,000 psi. The porous carbonaceous particulate material of the present disclosure is also characterized by having a true density, (“PT”), of 1.2 g/cc≦PT≦2.0 g/cc, when milled to−-200 mesh and has a d50 particle size distribution of about 15 μm. This is the consequence of the instant material exhibiting a high level of closed porosity with very small pores, in contrast with prior art materials that would have a wider range pore sizes for the closed pores.

    摘要翻译： 提供了一种碳质颗粒材料，其特征在于在4000psi至10,000psi之间具有大于或等于（≥3％）的流体介质（“VR”）的可逆容积膨胀/收缩。 本公开的多孔碳质颗粒材料的特征还在于，当研磨至200目并具有d50粒径时，其真密度（“PT”）为1.2g / cc和nlE; 2.0g / cc 分布约15μm。 这是现有材料表现出具有非常小孔隙的高水平闭孔率的结果，与现有技术的材料相比，该材料对于闭孔具有更宽的孔径。
