Quantitative X-Ray Microanalysis of Ultra-Thin Resin-Embedded Biological Samples,itivity restrictions usually indicate microanalysis of thin section (≤ 1 μm) by energy dispersive detectors. Amongst briefly reviewed options for production of thin sections, the merits of low temperature freeze-drying, vacuum resin embedding and dry sectioning are presented, particularly for the lo作者: 種屬關(guān)系 時間: 2025-3-22 22:18 作者: 閑蕩 時間: 2025-3-23 02:00 作者: expository 時間: 2025-3-23 07:45 作者: Dictation 時間: 2025-3-23 15:04
