Metallic (Cu, Cn) and intermetallic (Cu-Sn) nanoparticles have been synthesized through a chemical reduction in water solution of corresponding chloride salts with NaBH4 as a reducing agent at...

Scanning electron microscopy and X-ray diffraction were used to identify the microstructure morphology and composition. The spreading area and contact angle of the Sn–20Bi–x (x = 0, 0.1 wt% Al,...

2023年1月12日 · Successful segmentation enables the qualitative as well as quantitative analysis of the individual microstructure components. The current paper deals with the segmentation and classification of four basic microstructure components of the Zn-Al-Mg-Sn alloy system.

Surface plasmon resonance of metallic nanoparticles can be applied to photovoltaic devices. In this report, we propose Tin nanoparticles (Sn NPs) for crystalline silicon solar cells. Sn NPs...

2018年8月28日 · In this paper, we present the first publicly available human-annotated dataset of images obtained by the Scanning Electron Microscopy (SEM). A total of roughly 22,000 SEM images at the...

2023年7月13日 · 利用扫描电镜可以直接研究晶体缺陷及其产生过程，可以观察金属材料内部原子的集结方式和它们的真实边界，也可以观察在不同条件下边界移动的方式，还可以检查晶体在表面机械加工中引起的损伤和辐射损伤等。 最近很多同学跟我反映自己 没有什么实验室科研经历，或者说实验课都在划水，害怕面试的时候问到实验仪器一窍不通，该怎么去准备？ 本期通过一组图给大家介绍扫描电子显微镜（SEM）,觉得图还不够的同学可以点击文末…

2019年11月29日 · To the best of our knowledge, this paper is the first to study the pulse electrodeposition of Ni-Sn alloys from deep eutectic solvents especially since no systematic studies have been reported on the effect of applied pulse frequencies on the morphology and mechanical properties.

扫描电子显微镜（scanning electron microscope，SEM）是一种用于高分辨率微区形貌分析的大型精密仪器 [3]。 具有景深大、分辨率高，成像直观、立体感强、放大倍数范围宽以及待测样品可在三维空间内进行旋转和倾斜等特点。 另外具有可测样品种类丰富，几乎不损伤和污染原始样品以及可同时获得形貌、结构、成分和结晶学信息等优点。 目前，扫描电子显微镜已被广泛应用于 生命科学 、物理学、化学、司法、 地球科学 、材料学以及工业生产等领域的微观研究，仅在地球 …

2018年11月15日 · We report a thorough structural and magnetic study of Fe 3Sn produced either by solid state reaction or by mechanical alloying in order to figure out which of the two techniques is most suitable for obtaining the purest Fe3 Sn alloy. Solid state reaction of Fe and Sn starting powders results in a pure sample (100%) of Fe 3Sn.

A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.
