On the Role of Dual Active margin Collision for Exhuming the World's Largest Ultrahigh Pressure metamorphic Belt

ABSTRACT： A wide variety of tectonic models have been invoked to explain the exhumation of the world＇s largest ultrahigh pressure （UHP） orogenic belt, the Qinling Dabieshan Sulu belt in China, and its correlatives in Korea. most of these models assume that the orogen contains one main collisional suture between the north and South China cratons that collided in the mesozoic. new field data reveal that this model is too simplistic, and that the collision involved an additional mi- croplate, which initially rifted off the Yangtze craton. This continental microplate was partially sub- ducted beneath an active margin on the north China craton, and subsequently an additional active Andean-style margin developed on the southern margin of the Qinling microplate after collision, leav- ing the near-vertical microplate wedged between the two thickened and thermally softened margins. The thermo-mechanical environment of collision thus left a cold, thick, and buoyant microplate wedged between two easily deformed margins, which acted as power-law creep channels, accommodating rapid buoyancy-driven rise of a 2 000 km long wedge of the subducted microplate, which became intimately involved with the collisional process. An addi- tional segment of the northern Yangtze craton was subducted to ~100 kin, and formed a separate wedge that rose alongside the thermally softened margin of the Qinling mieroeontinent, and was bordered on the south by the recently thermally- softened rift zone where the Qinling mieroeonti- nent broke off the Yangtze eraton between Late Devonian and Permian times. Recognizing the dual active margins in Qinling-Dabieshan-Sulu orogen and the thermally-softened power-law creep channels sheds new light on understanding exhumation of the world＇s largest ultrahigh pressure belt. We propose that this model is generally applicable to other UHP belts worldwide.

THE nEXT InDUSTRIAL REVOLUTIOn:InTEGRATED SERVICES AnD GOODS

Journal of Systems Science and Systems Engineering 2012年第3期21卷 257-296页

作者： James m.TIEn College of Engineering University of MiamiCoral GablesFlorida 33146USA

The outputs or products of an economy can be divided into services products ana gooas products （due to manufacturing, construction, agriculture and mining）. To date, the services and goods products have, for the most part, been separately mass produced. However, in contrast to the first and second industrial revolutions which respectively focused on the development and the mass production of goods, the next - or third - industrial revolution is focused on the integration of services and/or goods; it is beginning in this second decade of the 21st Century. The Third Industrial Revolution （TIR） is based on the confluence of three major technological enablers （i.e., big data analytics, adaptive services and digital manufacturing）; they underpin the integration or mass customization of services and/or goods. As detailed in an earlier paper, we regard mass customization as the simultaneous and real-time management of supply and demand chains, based on a taxonomy that can be defined in terms of its underpinning component and management foci. The benefits of real-time mass customization cannot be over-stated as goods and services become indistinguishable and are co-produced - as ＂servgoods＂ - in real-time, resulting in an overwhelming economic advantage to the industrialized countries where the consuming customers are at the same time the co-producing producers.

Tubular pure copper grain refining by tube cyclic extrusion–compression(TCEC) as a severe plastic deformation technique

引用

Progress in natural Science:materials International 2014年第6期24卷 623-630页

作者： A.Babaei m.m.mashhadi School of mechanical Engineering College of Engineering University of Tehran

Tube Cyclic Extrusion–Compression(TCEC) method is a novel severe plastic deformation technique developed for grain refining of cylindrical tubes to ultrafine grained(UFG)/nanostructured ones. In this method, tubes are fully constrained and deformed between chamber and mandrel with a small neck zone. The principle of TCEC technique which was adopted to impose severe plastic strains to the tubular materials was explained. Also, the deformation and grain fragmentation mechanism during TCEC was analyzed. The material deformation characteristics during TCEC were numerically simulated by FE code of ABAQUS/Explicit. The FEm results demonstrated that TCEC technique was able to impose extremely high plastic strains. The TCEC method was successfully applied to a commercially pure copper(99.99%) and significant grain refinement was achieved. TEm observation demonstrated the refinement of grains from the initial size of 45 μm to 200–350 nm after four processing cycles of TCEC. microhardness measurements were carried out across the thickness of the initial and processed tubes. The results show good homogeneity of hardness distribution and an increase to 102 Hv from initial value of 55 Hv after four TCEC cycles. mechanical properties of the specimens were extracted from tensile tests. The obtained results documented notable increase in the yield and ultimate strengths, whereas the uniform and total elongations decreased. Fracture surfaces after tensile tests were investigated by scanning electron microscopy(SEm), and the observed morphology indicates ductile fracture mode after four cycles of TCEC.

Time-Dependent Zinc Desorption in Some Calcareous Soils of Iran

Pedosphere 2013年第2期23卷 185-193页

作者： m.BARAnImOTLAGH m.GHOLAmI Department of Soil Science College of Water and Soil SciencesGorgan University of Agricultural Sciences and Natural Resources

Desorption of zinc （Zn） from soil is an important factor governing Zn concentration in the soil solution and Zn availability to plants. Batch experiments were performed to study the kinetics of Zn desorption by diethylenetriaminepentaacetic acid （DTPA） from 15 calcareous soil samples taken from Golestan Province in northern Iran. Soils were equilibrated with 0.005 mol L-1 DTPA solutions for 0.25 to 192 h. The results showed that the extraction process consisted of rapid extraction in the first 2 h followed by much slower extraction for the remainder of the experiment. Desorption kinetic data was fitted to pseudo-first-order kinetic model. The experimental data were found to deviate from the straight line of the pseudo-first-order plots after 2 h. The model of two first-order reactions was fitted to the kinetic data and allowed to distinguish two pools for Zn： a labile fraction （Q1）, quickly extracted with a rate constant kl, and a slowly labile fraction （Q2）, more slowly extracted with a rate constant k2. The applicability of pseudo-second-order model in describing the kinetic data of Zn desorntion was also evaluated.

Band structure of monolayer of graphene, silicene and silicon-carbide including a lattice of empty or filled holes

引用

Journal of Semiconductors 2018年第8期39卷 10-19页

作者： n.nouri G.Rashedi Department of Physics Faculty of Sciences University of Isfahan

We have developed a π-orbital tight-binding Hamiltonian model taking into account the nearest neighbors to study the effect of antidot lattices(two dimensional honeycomb lattice of atoms including holes) on the band structure of silicene and silicon carbide(SiC) sheets. We obtained that the band structure of the silicene antidot superlattice strongly depends on the size of embedded holes, and the band gap of the silicene antidot lattice increases by increasing of holes diameter. The band gap of SiC antidot lattice, except for the lattice of the small unit cell, is independent of the holes diameter and also depends on the distance between holes. We obtained that, the band gap of the SiC antidot lattice is the same as the band gap of the corresponding sheet without hole. Also, the electronic properties of the SiC antidot superlattice occupied either by carbon or by silicon atoms are investigated,numerically. Furthermore, we study the effect of occupation of graphene antidot by Si atoms and vice versa. Also,we have calculated the band structure of graphene and silicene antidot lattice filled by Si + C atoms. Finally, we compute the band structure of the SiC antidot lattice including the holes which are filled by C or by Si ***, in this paper we have generalized the method of paperabout graphene antidot with empty holes to the cases of filled holes by different atoms and also to the case of silicene and silicon carbide antidot lattices.

Photovoltaic conversion was enhanced by directly assemble of a network of single-walled carbon nanotubes(SWnTs) onto the surface of n-p junction silicon solar cells. When the density of SWnTs increased from 50 to 400 tubes μm^(-2), an enhancement of 3.92% in energy conversion efficiency was typically obtained. The effect of the SWnTs network is proposed for trapping incident photons and assisting electronic transportation at the interface of silicon solar cells.
