2Characterization of the Hot Deformation Behavior of Cu–Cr–Zr Alloy by Processing Maps显示文摘Hot deformation behavior of the Cu–Cr–Zr alloy was investigated using hot compressive tests in the temperature range of 650–850 °C and strain rate range of 0.001–10 s-1. The constitutive equation of the alloy based on the hyperbolic-sine equation was established to characterize the flow stress as a function of strain rate and deformation temperature. The critical conditions for the occurrence of dynamic recrystallization were determined based on the alloy strain hardening rate curves. Based on the dynamic material model, the processing maps at the strains of 0.3, 0.4 and 0.5were obtained. When the true strain was 0.5, greater power dissipation efficiency was observed at 800–850 °C and under0.001–0.1 s-1, with the peak efficiency of 47%. The evolution of DRX microstructure strongly depends on the deformation temperature and the strain rate. Based on the processing maps and microstructure evolution, the optimal hot working conditions for the Cu–Cr–Zr alloy are in the temperature range of 800–850 °C and the strain rate range of 0.001–0.1 s-1.Yi Zhang Hui-Li Sun Alex A.Volinsky Bao-Hong Tian Zhe Chai Ping Liu Yong Liu 2016Acta Metallurgica Sinica(English Letters)2016,29,5:3
3Single atom and defect engineering of CuO for efficient electrochemical reduction of CO_(2) to C_(2)H_(4)显示文摘Electrochemical CO_(2) transformation to high‐value ethylene(C_(2)H_(4))at high currents and efficiencies is desired and yet remains a grand challenge.We show for the first time that coupling single Sb atoms and oxygen vacancies of CuO enable synergistic electrocatalytic reduction of CO_(2) to C_(2)H_(4) at low overpotentials.Highly dispersed Sb atoms occupying metal substitutional sites of CuO are synthesized under mild conditions.The overall CO_(2) reduction faradaic efficiency(FE)reaches 89.3±1.1%with an FE toward C_(2)H_(4) exceeding 58.4%at a high‐current density of 500 mA/cm^(2).Addition of the p‐block metal is found to induce transformation of CuO from flakes to nanoribbons rich in nanoholes and oxygen vacancies,greatly enhancing CO_(2) adsorption and activation while suppressing hydrogen evolution.Further density functional theory calculations with in situ X‐ray diffraction reveal that combining Sb sites and oxygen vacancies prominently lessen the dimerization energy of adsorbed CO intermediate,thus boosting the conversion of CO_(2) to produce C_(2)H_(4).This study provides a new perspective for promoting selective C-C coupling for electrochemical CO_(2) reduction.Senlin Chu Changwoo Kang Woonghyeon Park Yu Han Song Hong Leiduan Hao Hao Zhang Tsz Woon Benedict Lo Alex W.Robertson Yousung Jung Buxing Han Zhenyu Sun 2022SmartMat2022,3,1:3
4Imaging pancreatobiliary ductal system with optical coherence tomography: A review显示文摘An accurate, noninvasive and cost-effective method of in situ tissue evaluation during endoscopy would be highly advantageous for the detection of dysplasia or early cancer and for identifying different disease stages. Optical coherence tomography(OCT) is a noninvasive, high-resolution(1-10 μm) emerging optical imaging method with potential for identifying microscopic subsurface features in the pancreatic and biliary ductal system. Tissue microstructure of pancreaticobiliary ductal system has been successfully imaged by inserting an OCT probe through a standard endoscope operative channel. High-resolution OCT images and the technique's endoscopic compatibility have allowed for the microstructural diagnostic of thepancreatobiliary diseases. In this review, we discussed currently available pancreaticobiliary ductal imaging systems to assess the pancreatobiliary tissue microstructure and to evaluate varieties of pancreaticobiliary disorders and diseases. Results show that OCT can improve the quality of images of pancreatobiliary system during endoscopic retrograde cholangiopancheatography procedure, which may be important in distinguishing between the neoplastic and non-neoplastic lesions.Mohammad S Mahmud Gray R May Mohammad M Kamal Ahmed S Khwaja Carry Sun Alex Vitkin Victor XD Yang 2013World Journal of Gastrointestinal Endoscopy2013,5,11:2

7Gastric duplication cyst mimicking large cystic lymphangioma in an adult: A rare case report and review of the literature显示文摘BACKGROUND Gastric duplication cysts(GDCs)are a relatively uncommon congenital developmental abnormality,mainly occurring in infants but very rarely in adults.Because of the variability in clinical presentation,it is often quite challenging to diagnose GDCs in adults.We are presenting a case report of an adult diagnosed operatively as having a GDC with a literature review to summarize clinical and imaging features and the treatment selections of GDCs in adults so that doctors could have a comprehensive understanding of this disease and make a precise diagnosis and a suitable therapeutic decision for patients.CASE SUMMARY A 51-year-old man presented with recurrent epigastric pain and fullness for two years.No significant findings were noted during physical examination and routine blood tests were unremarkable.An abdominal ultrasound revealed a large cyst in the upper left abdominal quadrant.A following contrast-enhanced abdominal computed tomography(CT)scan demonstrated a hypodense cystic lesion between the spleen and stomach.The lesion had scattered calcification in the cyst wall without any significant enhancement.The lesion was initially thought to be a cystic lymphangioma.The patient underwent a surgical resection and intraoperatively it was noted that the lesion was closely adherent to the greater curvature of the stomach.Subsequently,a resection of the gastric mass along with a partial gastrectomy was performed.The patient recovered quickly with a complete symptomatic relief and did not show any further complications during the 8-month follow-up.CONCLUSION GDCs are quite rare in adults,with a multitude of symptoms,which is quite challenging for precise diagnosis before histological examination.Some imaging techniques involving CT,magnetic resonance imaging,and endoscopic ultrasound could provide valuable morphological features for differential diagnosis.Fang-Yi Xv Alex Sun Yi Gan Hong-Jie Hu 2019World Journal of Clinical Cases2019,7,15:1

14Single-atom catalysts for electrochemical N_(2)reduction to NH_(3)显示文摘The increasing demand for clean energy and growing concerns regarding environmental sustainability have led to greater attention devoted toward the production of clean fuels via green chemistry.In this respect,ammonia is a green alternative to fossil fuels and can serve as a clean energy source.There is now great interest in realizing the electrochemical reduction in atmospheric nitrogen(N_(2))for cheap,environmentally friendly and reliable ammonia(NH_(3))production worldwide.However,the robustness of the triple bond in N2 and the low efficiency of candidate catalysts limit the utility of this conversion.Single atom catalysts have been found to be more effective than nanoparticles due to their unique properties,and thus have been studied extensively for the nitrogen reduction reaction.In this review,we have covered the recent advances in design and synthesis of noble metal and non-noble metal single atom catalysts for the electrochemical reduction in nitrogen during the years 2018-2022.The catalyst efficiencies,with reference to coordination preferences and theoretical studies have been discussed.Moreover,we also provide insights into the current challenges and some considerations for further future studies.Muhammad Saqlain lqbal Zhi-Bo Yao Yu-Kun Ruan Ramsha Iftikhar Lei-Duan Hao Alex WRobertson Syed Muhammad Imran Zhen-Yu Sun 2023Rare Metals2023,42,4:1
