Trans-Scale Mechanics: Looking For The Missing Links Between Continuum And Micro/Nanoscopic Reality

Problems involving coupled multiple space and time scales offer a real challenge for conventional frameworks of either particle or continuum mechanics. In this paper, four cases studies (shear band formation in bulk metallic glasses, spallation resulting from stress wave, interaction between a probe tip and sample, the simulation of nanoindentation with molecular statistical thermodynamics) are provided to illustrate the three levels of trans-scale problems (problems due to various physical mechanisms at macro-level, problems due to micro-structural evolution at macro/micro-level, problems due to the coupling of atoms/molecules and a finite size body at micro/nano-level) and their formulations. Accordingly, non-equilibrium statistical mechanics, coupled trans-scale equations and simultaneous solutions, and trans-scale algorithms based on atomic/molecular interaction are suggested as the three possible modes of trans-scale mechanics.

Evolução estrutural das zonas de cisalhamento dúcteis na porção centro-leste do domínio da Zona Transversal na Província Borborema

A área estudada está inserida no Domínio Transversal da Província Borborema. As unidades litoestratigráficas que compõem o embasamento paleoproterozócio (riaciano) são representadas por rochas ortoderivadas dos Complexos Salgadinho e Cabaceiras. Esses complexos foram individualizados de acordo com as suas diferenças composicionais, texturais e/ou geocronológicas. As rochas metassedimentares de idade paleoproterozóica (Orosiriano) foram interpretadas como constituintes do Complexo Sertânia. O magmatismo no estateriano é caracterizado por ortognaisses sienogranítcos da Suíte Carnoió-Caturité e por metanortositos do Complexo Metanortosítico Boqueirão. As unidades litoestratigráficas do Neoproterozóico são representadas por sucessões metassedimentares Criogenianas do Complexo Surubim e ortognaisses granodioríticos e sienograníticos do início do Ediacarano, denominados de Complexo Sumé e Ortognaisse Riacho de Santo Antônio, respectivamente. O magmatismo granítico do Ediacarano foi caracterizado pelo alojamento dos Plutons Inácio Pereira e Marinho. Os dados geocronológicos (U-Pb em zircão) obtidos indicam, no mínimo, o desenvolvimento de três eventos tectono-magmáticos. As idades de 2042 + 11Ma e 1996 + 13Ma obtidas nos ortoanfibolitos do Complexo Cabaceiras foram interpretadas como a idade de cristalização do protólito e metamorfismo, respectivamente. A idade de 1638 + 13Ma proveniente de hornblenda ortognaisse sienogranítico da Suíte Carnoió-Caturité foi interpretada como a idade de cristalização do protólito, marcando um evento magmático Estateriano de afinidade anorogênica. A idade de 550 + 3.1Ma encontrada em monzogranito porfirítico do Pluton Marinho é um registro do último evento magmático no final do Ediacarano, associado ao estágio tardio de desenvolvimento da Zona de Cisalhamento Coxixola. Os dados estruturais permitiram a individualização de três fases de deformação dúcteis, individualizadas como D1, D2 e D3. A fase D1 foi responsável pela geração de uma foliação S1, observada somente na charneira de dobras F2. O evento D2 é assinalado por uma tectônica contracional com transporte para NNW, observado a partir de bandas de cisalhamento assimétricas e dobras de arrasto em cortes paralelos a lineação de estiramento (L2x). Zonas de cisalhamento dúcteis de geometria e cinemática distintas desenvolveram-se durante a fase D3. As zonas de Cisalhamento Boa Vista, Carnoió e Congo estão orientadas na direção NE-SW e exibem cinemática sinistral em cortes paralelos à lineação de estiramento (L3x). As terminações meridionais dessas zonas de cisalhamento estão conectadas com a Zona de Cisalhamento Coxixola. Essa zona de cisalhamento, de direção WSW-ENE e cinemática destral, atravessa toda a área de estudo, com uma espessura média de rochas miloníticas de 300m. A Zona de Cisalhamento Inácio Pereira ocorre na porção leste da área de estudo, orientada na direção WNW-ESE. A análise geométrica e cinemática dessa zona de cisalhamento sugere uma evolução deformacional através de regime transpressivo oblíquo sinistral. O padrão anastomosado final resultante do desenvolvimento de todas as zonas de cisalhamento da área é relacionado à evolução estrutural de um sistema de zonas de cisalhamento dúcteis conjugadas.

Reversible CO2 absorption by the 6H perovskite Ba 4Sb2O9

A novel compound for carbon capture and storage (CCS) applications, the 6H perovskite Ba4Sb2O9, was found to be able to absorb CO2 through a chemical reaction at 873 K to form barium carbonate and BaSb2O6. This absorption was shown to be reversible through the regeneration of the original Ba4Sb 2O9 material upon heating above 1223 K accompanied by the release of CO2. A combined synchrotron X-ray diffraction, thermogravimetric, and microscopy study was carried out to characterize first the physical absorption properties and then to analyze the structural evolution and formation of phases in situ. Importantly, through subsequent carbonation and regeneration of the material over 100 times, it was shown that the combined absorption and regeneration reactions proceed without any significant reduction in the CO2 absorption capacity of the material. After 100 cycles the capacity of Ba4Sb2O9 was ∼0.1 g (CO 2)/g (sorbent), representing 73% of the total molar capacity. This is the first report of a perovskite-type material showing such good properties, opening the way for studies of new classes of inorganic oxide materials with stable and flexible chemical compositions and structures for applications in carbon capture. © 2013 American Chemical Society.

Thermal annealing behaviour of Pt on n-GaN Schottky contacts

The structural evolution and temperature dependence of the Schottky barrier heights of Pt contacts on n-GaN epilayer at various annealing temperatures were investigated extensively by Rutherford backscattering spectrometry, x-ray diffraction measurements, Auger electron spectroscopy, scanning electron microscopy and current-voltage measurements. The temperature dependence of the Schottky barrier heights may be attributed to changes of surface morphology of Pt films on the surface and variation of nonstoichiometric defects at the interface vicinity. Experimental results indicated the degradation of Pt contacts on n-GaN above 600 degreesC.

取向聚烯烃在单轴拉伸下的结构演变 -同步辐射小角X射线散射研究

典型的结晶聚合物在受到单轴拉伸时，其应力-应变曲线都会经历弹性变形、应变软化、应变硬化以及断裂的四个阶段，在这些过程中，聚合物内部经历了非常复杂的变化：从球晶结构转变成纤维结构最后至分子链解取向和断裂。尽管已经有很多的实验研究结晶聚合物的形变过程，但是对其中的形变机理仍然存在很多争论。本论文的主要思路就是采用取向态的聚合物这一简单的结构来模拟聚合物微观结构在受到外力作用时，在各个阶段的所经历的形貌演变，并基于这些实验数据提出结晶聚合物的形变机理。本文的主要内容包括： 1、选取了预取向的聚丙烯将其在三个不同的方向下拉伸，分别是拉伸方向平行于、垂直于片晶组的法线方向以及与片晶组的法线方向成45角，以模拟处于外力场中球晶内具有代表性的三组片晶的形变情况，希望对球晶结构转变成纤维结构这一塑性形变机理提供进一步的理解。三个实验分别表现出了三种不同的样品内部结构演变过程，综合所有的结果我们可以得出结晶聚合物发生屈服是片晶的塑性形变能力与非晶区弹性形变能力相互作用的结果。 2、 观察冷拉取向的聚乙烯样品在单轴拉伸下的形貌演变。这个过程相当于结晶聚合物成纤后的继续拉伸至断裂的过程。这一实验同时用于模拟研究聚乙烯塑料管材中的慢速裂纹扩展问题。因为聚乙烯裂纹前端是银纹结构即由高度取向的纤维连接裂纹的表面。裂纹的扩展是伴随着银纹中的纤维断裂的过程。实验数据表明了取向聚乙烯内部是由纤维组成的，纤维内部包含着几束由取向的片晶组构成的微纤。在拉伸的过程中由片晶组长周期的增加，微纤的滑移，纤维的滑移协同运动完成了外部的宏观形变。 3、 聚合物在生产加工过程中，样品会不可避免地受到剪切流动的作用。而受到剪切作用后的，聚合物分子大分子链或链段、微晶必然要表现出不同程度的取向，最终对聚合物材料力学性能会产生很重要的影响。因此研究剪切场下聚合物晶体结构的演化对于了解聚合物材料的加工和使用性能是非常重要的。等规聚丙烯在剪切过程中会出现新的晶型晶，我们发现虽然在剪切条件下生成的晶的片晶比聚丙烯中正常的晶要厚，但是实际上却表现出了比晶更好的流动行为。晶的稳定性要比晶的差，具有较低的熔点。因此我们认为片晶的塑性形变的能力除了与片晶厚度相关也与晶体的平衡熔点有关。 综上所述，我们利用同步辐射小角X射线散射手段对取向聚烯烃在单轴拉伸下的行为进行了广泛和深入的研究，发现了一些新现象，发展了文献中原有的理论，得到了单轴拉伸下取向聚乙烯和聚丙烯的形变机理。

聚苯乙烯薄膜溶胀/沉淀过程中的微观结构演化

本论文以聚苯乙烯薄膜为研究对象,研究应用溶剂/非溶剂连续处理而改变聚苯乙烯薄膜结构的方法。首先采用旋转涂膜法制备聚苯乙烯薄膜，利用谱学椭圆偏振仪、同步辐射掠入射超小角X射线散射与X射线反射方法来联合测定薄膜性质，进行了以下实验： 一． 离线实验：聚苯乙烯的四氢呋喃溶液在经亲水性预处理的硅片基底上旋转涂膜，退火后，聚苯乙烯薄膜连续浸入其溶剂N,N-二甲基甲酰胺与非溶剂乙醇，经过溶胀和沉淀过程，彻底改变了原来薄膜的表面结构，原子力显微镜和掠入射小角X射线散射在薄膜表面实验结果清晰显示，薄膜表面形成了不同尺度的聚苯乙烯聚集体，。结果表明同步辐射掠入射小角X射线散射是一种新颖，简单易行的观察薄膜表面结构的强有力的手段。溶剂/非溶剂处理聚苯乙烯表面的方法简便易行，是一种非常有潜力的改善聚苯乙烯表面结构的方法。 二． 在线实验：根据离线实验结果，自行设计制造了一个椭圆偏振仪样品池，用椭圆偏振仪上在线跟踪气态溶剂/非溶剂处理聚苯乙烯薄膜，努力追踪溶剂/非溶剂处理聚苯乙烯薄膜过程中，薄膜结构的动态变化规律。结果显示，气态溶剂/非溶剂处理薄膜表面的结果与用液态溶剂/非溶剂处理的结果不同，处理后的薄膜表面性质没有明显改变，而且加入非溶剂后椭偏参数随时间的一级指数衰减与膜厚成线性关系。原因可能是样品池内为混合气体，非溶剂蒸汽压不够，不足以引起聚苯乙烯分子链的沉淀，溶胀的薄膜又回复原态。

Homogeneous Epitaxial Growth of N,N '-di(n-butyl)quinacridone Thin Films on Ag(110)

The structural evolution of the ordered N-N' dibutyl-substituted quinacridone (QA4C) multilayers (3 MLs) has been monitored in situ and in real time at various substrate temperatures using low energy electron diffraction (LEED) during organic molecular beam epitaxy (MBE). Experimental results of LEED patterns clearly reveal that the structure of the multilayer strongly depends on the substrate temperature. Multilayer growth can be achieved at the substrate temperatures below 300 K, while at the higher temperatures we can only get one ordered monolayer of QA4C. Two kinds of structures, the commensurate and incommensurate one, often coexist in the QA4C multilayer. With a method of the two-step substrate temperatures, the incommensurate one can be suppressed, and the commensurate, on the other hand, more similar to the (001) plane of the QA4C bulk crystal, prevails with the layer of QA4C increasing to 3 MLs. The two structures in the multilayers are compressed slightly in comparison to the original ones in the first monolayer.

GIUSAXS and AFM Studies on Surface Reconstruction of Latex Thin Films during Thermal Treatment

The structural evolution of a single-layer latex film during annealing was studied via grazing incidence ultrasmall-angle X-ray scattering (GIUSAXS) and atomic force microscopy (AFM). The latex particles were composed of a low-T-g (-54 degrees C) core (n-butylacrylate, 30 wt %) and a high-T-g (41 degrees C) shell (t-butylacrylate, 70 wt %) and had an overall diameter of about 500 nm. GIUSAXS data indicate that the q(y) scan at q(z) = 0.27 nm(-1) (out-of-plane scan) contains information about both the structure factor and the form factor. The GIUSAXS data on latex films annealed at various temperatures ranging from room temperature to 140 degrees C indicate that the structure of the latex thin film beneath the surface changed significantly. The evolution of the out-of-plane scan plot reveals the surface reconstruction of the film. Furthermore, we also followed the time-dependent behavior of structural evolution when the latex film was annealed at a relatively low temperature (60 degrees C) where restructuring within the film can be followed that cannot be detected by AFM, which detects only surface morphology.

Sol-gel deposition of calcium silicate red-emitting luminescent films doped with Eu3+

Eu3+-activated calcium silicate (CaO-SiO2:Eu3+) luminescent films were prepared by the sol-gel method. The structural evolution of the film was studied by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM), and the luminescence properties of the phosphor films were investigated as a function of heat treatment temperature. The XRD study indicates that a kilchoanite phase forms in the film sintered at 800 degreesC, which is different from that in gel powder treated under the same conditions. The SEM results show that the film thickness decreases and the particles in the film become smaller with increasing heat treatment temperature. The CaO-SiO2:Eu film shows the characteristic emission of Eu3+ under UV excitation, with the Eu3+ D-5(0)-->F-7(2) band (616 nm) being the most prominent. A large difference in the Eu3+ lifetime is observed between the film samples treated at 500 and 700 degreesC (or above). Concentration quenching occurs when the Eu3+ doping concentration is above 6 mol% of Ca2+ in the film.

渤海湾地区前第三系构造特征及其演化研究

Based on fine structural interpretation on seismic profiles of buried-hills in Huanghua depression, structural interpretation and balanced cross-section restoration of regional seismic profiles, drawing structural maps of main seismic interfaces, residual strata distribution of different ages in the Bohai Bay region and structural survey in the western Shandong uplifted area and the intracontinental orogeny of Yanshan mountain, the paper has studied pre-tertiary structural styles and tectonic evolution of the Bohai Bay region. There mainly develop 5 types of pre-tertiary structural style that are extension structure, compression structure, strike-slip structure, negative inversion structure and sliding structure in the Bohai Bay region. Among these 5 types of structural style, extension structure develops detachment fault and its controlling fault terrain structure and fault break slop; compression structure develops reverted fold, fault propagation fold, fault bent fold, imbricate thrust structure and triangle zone; strike-slip structure develops positive flower structure, negative flower structure, en-echelon structure and brush structure; negative reversion structure develops Indosinian compression and Yanshanian extension negative reversion structure, late Yanshanian compression and Cenozoic extension negative reversion structure; sliding structure develops interlayer sliding structure and detachment structure. According to Cangdong fault of SN direction, Zhangjiakou – Penglai fault and Qihe – Guangrao fault of NWW direction, the Bohai Bay region can be divided into 6 sub-regions in which structural direction and style is different from each other. Structural maps of bottom boundary of Cenozoic and upper Paleozoic manifest that main NNE structural direction is formed from late Yanshanian to Himalayan movement and minor NWW structural direction and a string of area more than 8000m are mainly suggest that Indosinian tectonic pattern strongly influence on Yanshanian and Himalayan movement. Residual strata distribution characteristics of middle to upper Neoproterozoic in the Bohai Bay region manifest that middle- to neo- aulacogen position may be corresponding to late Mesozoic uplifted zone. Residual Paleozoic distribution characteristics of main ENN suggest that structural alteration should be resulted from late Yanshanian to Himalayan movement while which of minor NWW structures suggest that deeper structure should restrict shallower structure. Structural patterns of main EW fold direction in the Bohai Bay region and thrust structure in eastern part are formed late Triassic in studied area. Granite magma intrusion of early to middle Jurassic mainly develops Yanshan mountain zone. Late Mesozoic rifting basins of NEE direction are widely distributed in the Bohai Bay region and granite magma intrusions are mainly distributed in Tancheng – Rongcheng zone. Mesozoic structural evolution in the Bohai Bay region is related to scissor convergent from east to west between North China plate and Yangtze plate and gradually reinforcing of the west circum-pacific tectonic tract while basin and range province of late Jurassic and early Cretaceous may be mainly related to lithospheric thinning of North China craton in late Mesozoic.

渤海湾盆地前第三系构造演化与煤成气成藏研究

The disequilibrium between supply and demand the east part of North China accelerated natural gas exploration in Bohai bay basin. Exploration practice showed that coal-derived gas is important resource. In searching of big to middle scaled coal derived gas field, and realize successive gas supply, the paper carried out integrated study on structural evolution of Pre-Tertiary and evaluation of reservoir forming condition of coal-derived gas. Study work of the paper was based on the following condition: available achievement in this field at present, good understanding of multiphase of tectonic movement. Study work was focused on geological evolution, source rock evaluation and dissection key factors controlling reservoir forming. Based on analysis of seismic data, drilling data, tectonic style of Pre-Tertiary was subdivided, with different tectonic style representing different tectonic process. By means of state of the art, such as analysis of balanced cross section, and erosion restoration, the paper reestablished tectonic history and analyzed basin property during different tectonic phase. Dynamic mechanism for tectonic movement and influence of tectonic evolution on tectonic style were discussed. Study made it clear that tectonic movement is intensive since Mesozoic including 2 phase of compressional movement (at the end of Indo-China movement, and Yanshan movement), 2 phase of extensional movement (middle Yanshan movement, and Himalayan movement), 2 phase of strike slip movement, as well as 2 phase of reversal movement (early Yanshan movement, and early Himalayan movement). As a result, three tectonic provinces with different remnant of strata and different tectonic style took shape. Based on afore mentioned study, the paper pointed out that evolution of Bohai bay basin experienced the following steps: basin of rift valley type (Pt2+3)-craton basin at passive continental margin (∈1－2)-craton basin at active continental margin (∈3- O)-convergent craton basin (C-T1+2)-intracontinental basin (J＋K). Superposition of basins in different stage was discussed. Aimed at tectonic feature of multiple phases, the paper put forward concept model of superposition of tectonic unit, and analyzed its significance on reservoir forming. On basis of the difference among 3 tectonic movements in Mesozoic and Cenozoic, superposition of tectonic unit was classified into the following 3 categories and 6 types: continuous subsidence type (I), subsidence in Mesozoic and uplift for erosion in Cenozoic (II1), repeated subsidence and uplift in Mesozoic and subsidence in Cenozoic (II2), repeated subsidence and uplift in Mesozoic and uplift for erosion in Cenozoic (II3), uplift for erosion in Mesozoic and subsidence in Cenozoic (II4), and continuous uplift (III). Take the organic facies analysis as link, the paper established relationship between sedimentary environment and organic facies, as well as organic facies and organic matter abundance. Combined information of sedimentary environment and logging data, the paper estimated distribution of organic matter abundance. Combined with simulation of secondary hydrocarbon generation, dynamic mechanism of hydrocarbon generation, and thermal history, the paper made static and dynamic evaluation of effective source rock, i.e. Taiyuan formation and Shanxi formation. It is also pointed out that superposition of tectonic unit of type II2, type II4, and type I were the most favorable hydrocarbon generation units. Based on dissection of typical primary coal-derived gas reservoir, including reservoir forming condition and reservoir forming process, the paper pointed out key factors controlling reservoir forming for Carboniferous and Permian System: a. remnant thickness and source rock property were precondition; b. secondary hydrocarbon generation during Himalayan period was key factor; c. tectonic evolution history controlling thermal evolution of source rock was main factor that determine reservoir forming; d. inherited positive structural unit was favorable accumulation direction; e. fault activity and regional caprock determined hydrocarbon accumulation horizon. In the end, the paper established reservoir forming model for different superposition of tectonic units, and pointed out promising exploration belts with 11 of the first class, 5 of the second class and 6 of the third class.

天山南北山前盆地中-新生代沉积记录及其动力学分析

It has been long known that intense multiple Mesozoic-Cenozoic intracontinental deformations have controlled the grand scale basin-range structural evolution of the Tianshan and its adjacent basins. So it is important to study the sedimentary records of the piedmont basins along the two sides of the Tianshan synthetically for the continental geodynamic research.We carried out a magnetostratigraphy study on Cretaceous- Tertiary succession and U-Pb dating analysis of detrital zircons from the representative sandstone samples of the Mesozoic-Cenozoic deposits in Kuqa Subbasin, northern Tarim Basin, combining our previous results of multiple depositional records from different profiles including paleocurrent data, conglomerate clast, sandstone framswork grains, detrital heavy minerals and geochemistry analysis, so the multiple intracontinental tectonic processes of Tianshan and their depositional response in the Kuqa Subbasin can be revealed. The results show that the tectonic evolution of the Tianshan Orogen and the sedimentary processes of the Kuqa Subbasin can be divided into four periods: early Triassic(active period), from middle Triassic to late Jurassic(placid period), from early Cretaceous to Tertiary Paleocene(active period) and from Neogene to present (intensely active period). Simultaneously，the depositional records reveal the provenance types and tectonic attributes in different periods. As follows, the lower Triassic with a dominant age ranging from 250 to 290Ma of the Zircons, which were principally derived from alkali feldspar granites and alkaline intrusion obviously, relative to the magma activity in Permian. In middle Triassic-late Jurassic, the two samples collected from the Taliqike formation and the Qiakemake formation respectively show the age peak at 350～450Ma, which was relative to the subduction of the Tarim Block to Yili-Central Tianshan Plate. In this period the provenance of the Kuqa deposits was the Central Tianshan arc orogenic belts distantly with little height predominance.During early Cretaceous-Paleogene, two major zircons age spectra at 240~330Ma and 370~480Ma have been acquired, with some other not dominant age ranges, indicating complicated provenance types. In Neogene, the detrital zircons age dating ranges from 460 to 390 Ma primarily. What’s more, the newer chronology of the stratigraphy and the older source age, indicating that Tianshan was uplifted and exhumated further strongly. Further study on the heavy mineral and the detrital zircons age dating of the Mesozoic-Paleogene representative profiles in southern Junggar Basin, combined with the published results of the sandstone framework grains, we consider that it occurred obvious sedimentary and tectonic changes occurred in the inside of Jurassic, from late Jurassic to early Cretaceous and form early Cretaceous to late Cretaceous. On this faces, there are remarkable changes of the steady minerals and unstable minerals, the sandstone maturity and the age spectra of the detrital zircons. Compared the sedimentary records from the two sides of the Tianshan, We find that they are different obviously since Middle Jurassic. It can be concluded that Tianshan have uplifted highly enough to influence the paleo-climatic. According to the current strata division, the structural activity apparently showed a migration from north to south. That is to say, the South Tianshan uplift later than the north, especially from late Jurassic to early Cretaceous , but it was uplifted and exhumated more strongly. Furthermore, correlating the depositional records and tectonic styles in the Kuqa-South Tianshan basin-range conjugation site in the east with the west, the obvious differentiation between the west and the east from the Cretaceous especially in Tertiary along the Tianshan-Kuqa belt was revealed, probably showing earlier uplifting in the east while greater exhumation depth and sediment rates in the west. In addition, the contacting style of Kuqa subbasin to the Tianshan Orogenic belts and the basement structure are also inconsistent at different basin-range conjugation sites. It is probably controlled by a series of N-S strike adjusting belts within the Kuqa subbasin, or probably correlated with the material difference at the complicated basin-range boundary. The research on the Mesozoic-Cenozoic tectonic-depositional response in the piedmont basins along the two sides of the Tianshan shows that the basin-filling process was controlled by the intracontinental multicyclic basin-range interactions, especially affected by the intense tectonic differentiations of basin-range system, which can’t be illuminated using a single evolutionary model.
