  Asphalt production technology. Recent history and old problems

  摘要：

  The study of the history of engineering is not. only due to purely cognitive interest in the past but also to the realization of a fact which has finally become inarguable to us: "one who does not know the past will not see the future. " This article is dedicated to the development of domestic asphalt production technology in rite final third of the century. The subject and time were selected for both subjective and objective reasons. On one hand, we have not only been witnesses to but also participants in the events that rook place in this area in the indicated period of time. On the other hand, the properties of the initial feedstock changed significantly during this period (mixed West Siberian crudes became the fundamental feedstock), which exacerbated the existing process problems and stimulated attempts to solve thr,ll. Data from monographs and reviews published in the central press and articles from the journals Khimiya i Tekhnologiya Topliv i Masel [Chemistry and Technology of Fuels and Oils] and Neftepererabotka i Neftekhimiya [Petroleum Refining and Petrochemistry] were used, since the most important events and findings must have been included in these publications. Great attention is focused on the developments which significantly affected the subsequent evolution of asphalt production technology.

• Electrochemically Prepared Pore Arrays for Photonic-Crystal Applications

  In the last few years, photonic crystals have gained considerable interest due to their ability to “mold the flow of light.” Photonic crystals are physically based on Bragg reflections of electromagnetic waves. In simple terms, a one-dimensional (1D) photonic crystal is a periodic stack of thin dielectric films with two different refractive indices, n₁ and n₂. The two important geometrical parameters determining the wavelength of the photonic bandgap are the lattice constant, a = d₁(n₁) + d₂(n₂), and the ratio of d₁ to a (where d₁ is the thickness of the layer with refractive index n₁, and d₂ is the thickness of layer n₂). For a simple quarter-wavelength stack, the center wavelength λ of the 1D photonic crystal would be simply λ = 2n₁d₁ + 2n₂d₂. In the case of 2D photonic crystals, the concept is extended to either airholes in a dielectric medium or dielectric rods in air. Therefore, ordered porous dielectric materials like porous silicon or porous alumina are intrinsically 2D photonic crystals.

  在过去几年中，光子晶体因其能够“塑造光的流动”而引起了相当大的兴趣。光子晶体在物理上基于电磁波的布拉格反射。简单来说，一维（1D）光子晶体是由两种不同折射率的薄介质膜周期堆叠而成，这两种折射率分别为n₁和n₂。确定光子带隙波长的两个重要几何参数是晶格常数a = d₁(n₁) + d₂(n₂)，以及d₁与a的比值（其中d₁是具有折射率n₁的层的厚度，d₂是具有折射率n₂的层的厚度）。对于简单的四分之一波长堆叠，一维光子晶体的中心波长λ简单地为λ = 2n₁d₁ + 2n₂d₂。在二维光子晶体的情况下，这个概念扩展到介质中的气孔或空气中的介电棒。因此，有序多孔介质材料如多孔硅或多孔氧化铝本质上是二维光子晶体。
