Core Insights - The Chinese Academy of Sciences' Hefei Institute of Material Science has announced multiple government procurement intentions, with a total budget exceeding 528 million yuan for various instruments and equipment [2][3]. Procurement Overview - The procurement includes 27 items such as scanning electron microscopes, focused ion beam microscopes, transmission electron microscope analysis platforms, X-ray photoelectron spectroscopy, positron annihilation lifetime spectrometers, X-ray diffractometers, and CT non-destructive testing equipment, with an expected procurement date of December 2025 [3][4]. - The total procurement demand from the Hefei Institute this year has surpassed 1 billion yuan, indicating its status as a significant buyer in the market [4]. Instrument Details - **Focused Ion Beam Microscope (FIB)**: Utilizes a focused gallium ion beam for nanoscale processing and high-resolution imaging, with ion beam resolution of approximately 4-7 nm and electron beam resolution of up to 0.9 nm. It is widely used in materials science, semiconductor industry, biomedical applications, and geological archaeology [4]. - **X-ray Photoelectron Spectroscopy (XPS)**: A surface analysis technique that uses X-rays to excite photoelectrons, allowing for the identification of elemental composition, chemical states, and valence states with high sensitivity and non-destructive analysis. It is applicable in materials science, chemical engineering, energy sectors, and biomedical fields [5]. - **Positron Annihilation Lifetime Spectrometer**: A non-destructive characterization technique that measures the lifetime of positrons before annihilation, reflecting microstructural information such as vacancies and defects. It is used in materials science, energy sectors, and biomedical applications [6]. Detailed Procurement List - The procurement list includes various high-tech equipment with specific budget allocations, such as: - **Scanning Electron Microscope**: Budget of 600 million yuan [10] - **Focused Ion Beam Microscope**: Budget of 1.2 billion yuan [10] - **Transmission Electron Microscope**: Budget of 3.004 billion yuan [10] - **X-ray Photoelectron Spectroscopy**: Budget of 520 million yuan [11] - **CT Non-destructive Testing Equipment**: Budget of 195 million yuan [10] Research Institute Overview - The Hefei Institute of Material Science is located in Hefei, Anhui Province, covering an area of 2.65 square kilometers. It is known for its modern research facilities and beautiful natural scenery, housing multiple research units and recognized as one of China's top ten science tourism bases [14].
