| 1 | Usefulness of biodegradable stents constructed of poly-l-lactic acid monofilaments in patients with benign esophageal stenosis显示文摘AIM: To report 13 patients with benign esophageal stenosis treated with the biodegradable stent. METHODS: We developed a Ultraflex-type stent by knitting poly-l-lactic acid monofilaments. RESULTS: Two cases were esophageal stenosis caused by drinking of caustic liquid, 4 cases were due to surgical resection of esophageal cancers, and 7 cases were patients with esophageal cancer who received the preventive placement of biodegradable stents for post- endoscopic mucosal dissection (ESD) stenosis. The preventive placement was performed within 2 to 3 d after ESD. In 10 of the 13 cases, spontaneous migration of the stents occurred between 10 to 21 d after placement. In these cases, the migrated stents were excreted with the feces, and no obstructive complications were experienced. In 3 cases, the stents remained at the proper location on d 21 after placement. No symptoms of re-stenosis were observed within the follow-up period of 7 mo to 2 years. Further treatment with balloon dilatation or replacement of the biodegradable stent was not required. CONCLUSION: Biodegradable stents were useful for the treatment of benign esophageal stenosis, particularly for the prevention of post-ESD stenosis. | Yasuharu Saito Toyohiko Tanaka Akira Andoh Hideki Minematsu Kazunori Hata Tomoyuki Tsujikawa Norihisa Nitta Kiyoshi Murata Yoshihide Fujiyama | 2007 | World Journal of Gastroenterology2007，13，29： | 30 |
| 2 | 利用工业废料研制再生陶瓷初探(英文)显示文摘为了材料的充分循环,实现可持续发展,研究人员对回收工业废料用做陶瓷原料的技术进行了探索。本文阐述了再生陶瓷的研发状况,介绍了其粉体制备、坯料、配方、成型和烧成工艺,同时还针对节能环保的要求,研究了降低烧成温度和缩短烧成周期的策略。回收废瓷粉、废玻璃粉、燃烧灰烬、废粘土、废赤泥(氧化铝工业废料)和粉煤灰等工业废渣,配成多种陶瓷坯料,并测试了各种坯料配方的物理特性,确定了每种配方的烧成温度。配方中添加废玻璃可以有效地降低烧成温度。研制出的一种再生陶瓷的可行性坯料配方是:80-20%废瓷粉,20-80%燃烧灰烬,30%废玻璃粉。坯料干压成型,经1100℃烧成后,吸水率为9.9%,体积密度为2.52g/cm3。该坯料配方可采用速烧工艺。 | Nagae Hajime Suzuki Kazuo Sugiyama Toyohiko | 2005 | 陶瓷学报2005，26，1： | 8 |

| 4 | Holographic augmented reality display with conical holographic optical element for wide viewing zone显示文摘In this study, we propose a holographic augmented reality (AR) display with a wide viewing zone realized by using a special-designed reflective optical element. A conical holographic optical element (HOE) is used as such a reflective optical element. This conical HOE was implemented to reconstruct a diverging spherical wave with a wide spread angle. It has a sharp wavelength selectivity by recording it as a volume hologram, enabling augmented reality (AR) representation of real and virtual 3D objects. The quality of the generated spherical wave and the spectral reflectivity of the fabricated conical HOE were investigated. An optical superimposition between real and virtual 3D objects was demonstrated, thereby enhancing the validity of our proposed method. A horizontal viewing zone of 140° and a vertical viewing zone of 30° were experimentally confirmed. The fabrication procedure for the conical HOE is presented, and the calculation method of the computer-generated hologram (CGH) based on Fermat’s principle is explained in detail. | Yusuke Sando Kazuo Satoh Daisuke Barada Toyohiko Yatagai | 2022 | Light(Advanced Manufacturing)2022，3，1： | 4 |

| 6 | Comparative TEM investigation on the precipitation behaviors in Cu-15wt% Sn alloy显示文摘The decomposition and precipitation behaviors of a quenched Cu-15wt%Sn alloy as a function of aging temperature were investigated using transmission electron microscopy (TEM). Focused ion beam The decomposition and precipitation behaviors of a quenched Cu-15wt%Sn alloy as a function of aging temperature were investigated using transmission electron microscopy (TEM). Focused ion beam (FIB) was employed to assist TEM specimen preparation. At 300 °C, the decomposition of the supersaturated α' phase occurred at grain boundaries, displaying a cellular morphology. The lamellae were found with ζ and α phases, rather than with the equilibrium ε and α phases. The ζ and α phases exhibit a welldefined orientation relationship (OR) as (110)α//(0001)ζ; [112]α//[1210]ζ . On the other hand, at 320 °C, only incipient lamellar structures of several micron meters were observed, which were composed of the and α phases. At the same time, abundant intragranular precipitation of the ε phase in the form of platelets was observed, and OR as (111)α//(001)ε ; [110]α //[100]ε exists between ε phase and the a phase. These contrasting precipitation behaviors are discussed from the viewpoint of crystallographic coherency of these phases. | Zeng-Jie Wang Konno J.
