广西百色盆地油气勘探潜力分析

根据圈闭成因分类法,将盆地油气藏类型划分为构造油气藏、地层-岩性油气藏和复合油气藏三大类型及七种亚类型.油气藏类型受盆地不同的含油气结构层系控制,油藏主要围绕盆地主力生油凹陷呈环带分布,盆地不同构造带发育不同的油气藏类型.盆地资源探明率仅16.8%,还有可观的油气勘探潜力.盆地可划分为六个聚油单元,按各个单元的剩余资源潜力的分析,东部坳陷中央断凹-南部斜坡和西部坳陷是盆地今后勘探主要接替区带.

Study of the dimensional instabilities of laminated polypropylene films during heating treatments

Ensuring the geometrical stability of organic coatings is a key challenge for steel/polymer composites produced by the automotive industry to reduce the cars' weight. During the thermal treatment of painting, which exceeds the melting temperature of the organic part of the laminated film, polymer shrinkage may occur. It induces uncovered parts of the steel sheet which would present negative corrosion behavior in use. Two original and innovative experiments were presented. They enable to measure the deformation induced by the shrinkage and then to identify the microstructural mechanisms responsible for its appearance. Main results show strong influences of the macromolecular chains orientation induced by the film extrusion process and of the postheating parameters used to perform the painting curing. Raman spectroscopy and differential scanning calorimetry are used both to perform analysis of the microstructure evolution during heating treatments in terms of crystals melting, crystalline macromolecular chains disorientation, and volume damage healing. © 2012 Wiley Periodicals, Inc.

Combined Effects of Confinement and Macromolecular Crowding on Protein Stability

Confinement and crowding have been shown to affect protein fates, including folding, functional stability, and their interactions with self and other proteins. Using both theoretical and experimental studies, researchers have established the independent effects of confinement or crowding, but only a few studies have explored their effects in combination; therefore, their combined impact on protein fates is still relatively unknown. Here, we investigated the combined effects of confinement and crowding on protein stability using the pores of agarose hydrogels as a confining agent and the biopolymer, dextran, as a crowding agent. The addition of dextran further stabilized the enzymes encapsulated in agarose; moreover, the observed increases in enhancements (due to the addition of dextran) exceeded the sum of the individual enhancements due to confinement and crowding. These results suggest that even though confinement and crowding may behave differently in how they influence protein fates, these conditions may be combined to provide synergistic benefits for protein stabilization. In summary, our study demonstrated the successful use of polymer-based platforms to advance our understanding of how in vivo like environments impact protein function and structure.

Model of a polymer chain twisted inside a statistical segment. Poly(3‐hexylthiophene) in chloroform solutions

A set of hydrodynamic methods in extremely dilute solutions (determination of intrinsic viscosity [η ], translational diffusion D and flotation in a centrifugal field s ) was used in the studies of conformational properties, dimensions and equilibrium rigidity of individual molecules of a series of samples of poly(3‐hexylthiophene). Absolute molecular masses M _sD were determined. The Mark–Kuhn–Houwink equations for the range of M _sD from 2240 to 15 300 g mol^?1 are given. For the first time, an analysis of conformational properties and equilibrium flexibility of poly(3‐hexylthiophene) molecules was carried out using the model of a statistical segment containing a twisted polymer chain. © 2017 Society of Chemical Industry     

含硅阻燃大分子相容剂的制备及其在无卤阻燃聚乙烯复合材料中的协效作用

为验证含硅大分子相容剂在无卤阻燃体系中的协效阻燃作用,首先,以马来酸酐、硅橡胶与聚乙烯为原料,通过熔融接枝共聚制备了新型含硅阻燃大分子相容剂;然后,利用氢氧化铝、氢氧化镁和含硅大分子相容剂复配协同阻燃聚乙烯复合材料;最后,探讨了含硅大分子相容剂对复合材料极限氧指数、锥形量热参数、拉伸性能以及微观结构的影响。结果表明:与聚乙烯接枝马来酸酐相比,含硅大分子相容剂含量为10wt%时可使无机阻燃剂在基体树脂中分散较好;随着大分子相容剂含量的增加,复合材料的拉伸强度上升而断裂伸长率下降,极限氧指数提高至34.0%,燃烧时的热释放速率峰值和热释放总量均明显下降,说明含硅大分子相容剂除了能够在该复合材料中起到良好的相容作用外,还可以发挥较好的协效阻燃作用。
