Comprehensive Summary Monolithic perovskite/organic tandem solar cells (TSCs) have gained significant attention due to their easy device integration and the potential surpass Shockley–Queisser limit of single‐junction cells. However, surfaces wide‐bandgap perovskite films are densely populated with defects, leading severe non‐radiative recombination energy loss. As a consequence, power conversion efficiency (PCE) TSCs lags behind that other TSC counterparts. To address these issues, we...
Thermosetting blends of 4-aminophenoxyphthalonitrile (APN)/epoxy resin (ER) were investigated by differential scanning calorimetry (DSC), dynamic rheological analysis and thermogravimetric (TGA). The self-promoted curing behaviors processing properties the APN/ER prepolymers studied DSC under isothermal conditions. exhibited two-step polymerization reactions in absence any other additives. had large windows with low melt viscosity, size was dependent on APN monomer concentration. thermal...
Steel bridges are extremely damaged by fatigue subjected to cycling load. Therefore, it is often necessary put forward effective reinforcement strengthen steel structures during the daily maintenance. In this study, two repairing methods of high‐strength bolts and high‐modulus CFRP strips on basis stop‐hole repair method were introduced, respectively, investigate improvement cracked plates. First all, numerical analysis was conducted predict efficiency optimal parameters each method....
Abstract The use of precast pier segments is an integral part many accelerated bridge construction efforts. To effectively compensate for the adverse effect caused by concrete discontinuity between segments, replacing conventional rebar with high-strength steel (HSS) can be alternative to this issue. However, primary interest in design practice how evaluate seismic performance piers different strength. end, a evaluation method based on four characterized resilience parameters was developed,...
A constitutive equation formerly proposed by Okubo et al for one- and two-dimensional analysis was extended to the three-dimensional. The developed on basis of non-linear visco-elastic theory, it successfully applied problems such as long-term stability circular tunnel. In three-dimensional analysis, a constant volume-modulus assumed, analogy with equations Levy-Mises Prantl-Reuss discussed theoretically. Comprehensive FEM simulating constant-strain compression tests carried out tetrahedron,...
The development of laser melting deposition (LMD) technology has dramatically improved the processing efficiency complex components titanium alloys, allowing them to be widely used in aerospace and military equipment fields. In this work, study shear properties fracture mechanism LMD TC11 alloy scanning directions, compression tests double specimens at different temperatures extensive strain-rate ranges were carried out. Optical microscopy (OM) electron (SEM) employed observe metallographic...
Ni-20Cr-Eu2O3 composites were designed as new control rod materials and synthesized from Ni, Cr, Eu2O3 mixture powders via ball milling vacuum hot pressing. During milling, was fined, nano-crystallized, amorphized, then dissolved into matrix. The effect of content on the microstructure mechanics researched, corresponding mechanism discussed. relative densities, grain sizes, microhardness increased when increased. According to TEM observations, particles showed a semi-coherent relationship...
蘇通長江公路大橋(以下,蘇通大橋と略す)は,中国江蘇省の蘇州市と南通市の間を流れる長江(揚子江)に架かった斜張橋であり,2008年6月30日に正式に開通した.蘇通大橋は,最大支間長・杭基礎深さ・主塔高さ・メインケーブル長さの4項目において世界最大斜張橋となっており,本橋の建設プロジェクトは21世紀の中国における橋梁建設技術の集大成と言われている. 本稿では,蘇通大橋の設計,施工,維持管理の各段階における技術的な検討課題や対策,そして,新たに行われた研究開発課題などについて取りまとめた.特に,本橋の特徴でもある大規模で大深度の杭基礎,高い主塔部,中央径間およびケーブルの設計や施工について詳述した.また,本橋の維持管理においては,加速度計や腐食センサといった多種のセンサと性能評価モジュールを連動させた構造ヘルスモニタリング(SHM)システムが採用され,目視点検と組み合わせた維持管理システムが構築されているため,本稿ではセンサ配置や維持管理システムの構成等についても紹介することにした.
The devastating Wenchuan earthquake caused substantial flexural failure to Huilan flyover, located in Mianzhu of Sichuan, China. Based on the investigation bridge damage, three-dimensional mathematical models suitable for eigenvalue analysis and non-linear time-history dynamic are presented. In nonlinear analysis, elasto-plastic model, effect pounding slippage bearing studied by sensitivity analysis. Finally, causations seismic concluded. flyover is at Avenue city crosses several railway...
Orthotropic bridge deck is the main structural form of steel box girder deck. Due to dense U-rib weld and complex structure, it easy produce large deformation during welding. At present, determination amount mainly based on empirical value trial error method. It great significance for welding control study influence process orthotropic clarify parameters sequence. Based Marc software, finite element thermoelastic analysis method used simulate post-weld residual The sequence analyzed,...
In order to make clear the bond splitting behavior of reinforced concrete members with high strength concrete, eighteen simply supported beam tests were carried out. But comparing results existing design equation, following remarks obtained : (1) Bond is inversely proportional length for case having no transverse reinforcements. (2) The use reinforcements, especially supplement ties more effective concrete. (3) greater is, smaller difference between top bar and bottom is. Furthermore, new...
<p>The stop-hole method has been used widely to retard the fatigue crack growth of steel component in field bridge engineering. However, repaired by single without any additional reinforcement is liable again because drilling defects and new stress concentration region around hole. In this paper, two kinds strengthened methods, high strength bolt reinforced CFRP patched method, were investigated compared. Finite element analysis was conducted predict repair efficiency investigate...
