Diphenyl （4-hydroxyphenyl） hexadecyl phosphonium bromide （POH） -modified montmorillonite （POHMMT） was used to prepare a novel TiC14/MgC12.POHMMT compound catalyst and exfoliated iPP/POHMMT nanocomposites were prepared by the in situ intercalative polymerization of propylene with the TiC14/MgC12.POHMMT compound catalyst. The POH surfactants don＇t change the catalytic characteristic of the Z-N catalyst and the obtained PP presents high isotacticity, normal molecular weight and molecular weight distribution. The WAXD, SAXS and TEM results demonstrate the highly exfoliated iPP/POHMMT nanocomposites were produced by the in situ polymerization with this novel catalyst, while the intercalated iPP/Na＋MMT nanocomposites were produced with the TiC14/MgC12.Na＋MMT compound catalyst. Through this approach, in situ propylene polymerization can actually take place between the silicate layers and lead not only to PP with high isotacticity and molecular weight, but also to highly exfoliated PP nanocomposites.

Limestone calcined clay cement(LC3)is an environment-friendly and sustainable cementitious *** has recently gained considerable attention for the stabilization/solidification(S/S)of soils contaminated by heavy ***,the existing studies on S/S of Zn-contaminated soils using LC3 in terms of hydraulic conductivity and microstructural properties as compared to ordinary Portland cement(OPC)are *** study focuses on the evaluation of the mechanical,leaching,and microstructural characteristics of Zn-contaminated soils treated with different contents(0%,4%,6%,8%,and 10%)of low-carbon *** engineering performance of the treated Zn-contaminated soils is assessed over time using unconfined compressive strength(UCS),hydraulic conductivity(k),toxicity characteristic leaching procedure(TCLP),and synthetic precipitation leaching procedure(SPLP)*** results show that the UCS of Zn-contaminated soils treated with LC3 ranged from 1.47 to 2.49 MPa,which is higher than 1.63%–13.07%for those treated with *** k of Zn-contaminated soils treated with LC3 ranged from 1.16×10^(−8)to 5.18×10^(−8)cm/s as compared to the OPC treated *** the leaching properties,the leached Zn from TCLP and SPLP is 1.58–32..10 mg/L and 0.52.2.4.65 mg/L as the LC3 contents ranged from 4%to 10%.further,the corresponding pH modeling results indicate that LC3 promotes a relatively suitable dynamic equilibrium condition to immobilize the higher-level Zn *** addition,microscopic analyses demonstrate that the formations of hydration products,i.e.,Zn(OH)_(2.,Zn_(2.SiO_(4),calcium silicate hydrate(C–S–H),calcium silicate aluminate hydrate(C–A–S–H)gel,ettringite,and CaZn(SiO_(4))(H_(2.O),are the primary mechanisms for the immobilization of *** study also provides an empirical formula between the UCS and k to support the application of LC3-solidified Zn-contaminated soils in practical engineering in the field.

Two-dimensional(2.)WSe_(2.has received increasing attention due to its unique optical properties and bipolar *** WSe_(2.-based heterojunctions exhibit bidirectional rectification characteristics,but most devices have a lower rectification *** this work,the bi_(2.O_(2.Se/WSe_(2.heterojunction prepared by us has a typeⅡband alignment,which can vastly suppress the channel current through the interface barrier so that the bi_(2.O_(2.Se/WSe_(2.heterojunction device has a large rectification ratio of about 10^(5).Meanwhile,under different gate voltage modulation,the current on/off ratio of the device changes by nearly five orders of magnitude,and the maximum current on/off ratio is expected to be achieved *** photocurrent measurement reveals the behavior of recombination and space charge confinement,further verifying the bidirectional rectification behavior of heterojunctions,and it also exhibits excellent performance in light *** the future,bi_(2.O_(2.Se/WSe_(2.heterojunction field-effect transistors have great potential to reduce the volume of integrated circuits as a bidirectional controlled switching device.

文化建筑作为文化重要的物质化显现结果,承载着诸多非物质意涵。“本土性”则是阐述文化建筑各类意涵属性的根本,其多元化的特质决定了文化建筑对空间和形制的多样性要求。因此,文化建筑内装配式应用的范围十分有限。本文以“本土设计”策略为触媒,以酉阳四馆、徐州儿童友好中心为例,讨论装配建造模式下文化建筑的“本土性”建构过程。
