| 1 | 7xxx铝合金的应力腐蚀行为综述(英文)显示文摘应力腐蚀是材料在应力和腐蚀环境双重作用下使材料力学性能下降的行为。对于八种系列铝合金,2xxx、5xxx、7xxx铝合金对于应力腐蚀敏感。由于其优越的力学性能,7xxx铝合金广泛应用于航空、军事和结构工业。在这些7xxx铝合金中,应力腐蚀严重影响其力学性能,使其在服役过程中发生灾难性的失效。因此,研究该合金的应力腐蚀行为具有重要意义。本文综述了合金成分对合金在不同热处理条件下的显微组织演变,还综述了改善7xxx合金应力腐蚀性能的形变热处理和表面改性方法。此外,还综述了应力、预应变、合金成分和腐蚀环境对应力腐蚀行为的影响。还综述了焊缝、7xxx金属基复合材料和激光表面处理合金的应力腐蚀行为。 | A.C.UMAMAHESHWER RAO V.VASU M.GOVINDARAJU K.V.SAI SRINADH | 2016 | Transactions of Nonferrous Metals Society of China2016，26，6： | 12 |
| 2 | An automated spring-loaded needle for endoscopic ultrasound-guided abdominal paracentesis in cancer patients显示文摘AIM: To evaluate the feasibility of using an automatedspring-loaded needle device for endoscopic ultrasound(EUS)-guided abdominal paracentesis(EUS-P) to see if this would make it easier to puncture the mobile and lax gastric wall for EUS-P.METHODS: The EUS database and electronic medical records at Fukushima Medical University Hospital were searched from January 2001 to April 2011. Patients with a history of cancer and who underwent EUS-P using an automated spring-loaded needle device with a 22-gauge puncture needle were included. The needle was passed through the instrument channel and advanced through the gastrointestinal wall under EUS guidance into the echo-free space in the abdominal cavity and ascitic fluid was collected. The confirmed diagnosis of malignant ascites included positive cytology and results from careful clinical observation for at least 6 mo in patients with negative cytology. The technical success rate, cytology results and complications were evaluated.RESULTS: We found 11 patients who underwent EUS-P with an automated spring-loaded needle device. In 4 cases, ascites was revealed only with EUS but not in other imaging modalities. EUS-P was done in 7 other cases because there was minimal ascitic fluid and no safe window for percutaneous abdominal aspiration. Ascitic fluid was obtained in all cases by EUS-P. The average amount aspirated was 14.1 mL(range 0.5-38 mL) and that was sent for cytological exam. The etiology of ascitic fluid was benign in 5 patients and malignant in 6. In all cases, ascitic fluid was obtained with the first needle pass. No procedure-related adverse effects occurred.CONCLUSION: EUS-P with an automated springloaded needle device is a feasible and safe method for ascites evaluation. | Rei Suzuki Atsushi Irisawa Manoop S Bhutani Takuto Hikichi Tadayuki Takagi Goro Shibukawa Ai Sato Masaki Sato Tsunehiko Ikeda Ko Watanabe Jun Nakamura Srinadh Annangi Kazuhiro Tasaki Katsutoshi Obara Hiromasa Ohira | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，2： | 3 |

| 5 | Fabrication of Self-cleaning Antireflective Polymer Surfaces by Mimicking Underside Leaf Hierarchical Surface Structures显示文摘In this work, we utilized underside of four different plant leaves with different scale of hierarchical surface roughness to fabricate large area self-cleaning antireflective polymer surfaces. A simple and precise two-step soft-lithography replica molding technique was deployed by using polydimethylsiloxane (PDMS) polymer as a replicating material. In the first step, a negative PDMS replica was fabricated by using the underside of an original leaf as a template material. In the second step, a positive PDMS replica was fabricated through a negative PDMS replica used as a template. In order to study the non-wetting and light trapping properties, as-replicated polymer surfaces were characterized using Scanning Electron Microscopy (SEM), contact angle goniometer, and UV-Vis spectroscopy. SEM images confirmed the successful replication of complex hierarchical structures while contact angle measurement studies established retaining high non-wetting properties in polymer replicas. Optical studies suggest near zero reflection in normal mode and less than 5% diffuse reflection when measured using integrated sphere mode. These results have been correlated and explained with the air-liquid fraction and roughness factor as measured using three-dimensional optical profilometer. | Srinadh Mattaparthi Chandra Shekhar Sharma | 2019 | Journal of Bionic Engineering2019，16，3： | 2 |
