Industrial CT Helps Research into Green Energy Solutions

DTU Energy是丹麦技术大学的能源转换和存储系，已从2020欧洲杯下注官网尼康计量学to investigate energy-related materials non-destructively, such as those found in batteries, electrolysis cells and fuel cells.

Non-renewables generate approximately 85 per cent of the world’s energy today, but the issues with these finite resources have been known for a long time. Fossil fuels will one day be depleted but in the meantime, greenhouse gases such as carbon dioxide created by burning them are contributing to global warming.

In the search to find alternative resources to power the world, DTU Energy’s primary objective is to develop technologies for conversion and storage of energy derived from fluctuating sources such as wind and solar power generation.

Wind power, for example, may be stored by converting the electricity produced into a fuel such as hydrogen or a hydrocarbon.

CT provides insight that cannot be obtained from 2D images. The department’s pre-existing imaging methods include electron microscopy (SEM, TEM), FIB-tomography, TOF-SIMS, XPS, neutron imaging, scanning probe microscopy and diffraction tomography.

但是，对于物质研究，DTU需要一个CT系统，能够深入了解大多数能量转换和存储设备的复杂3D结构的特征。

电池和电化学细胞的结构可能很难单独从2D图像中分析。对于大多数表征方法，有必要打破或切割材料以调查内部零件。欧洲杯足球竞彩

With the CT facility, it is possible to investigate the devices in 3D non-destructively, giving information on internal surfaces and material structure such as the connectivity of pores, data that cannot be obtained from 2D images.

XT H 225 ST是尼康计量学的扩展模型，它允许扫描重量最高50千克的样品，直径300毫米。额外的尺寸和重量能力是DTU能量检查大型重型样品（例如太阳能，燃料和电解细胞）所需的。

CT扫描仪还配备了生成特定X射线光谱的多金属目标。除了标准的钨靶外，操作员还可以选择其他三种材料 - 银，钼和铜 - 使较低能量处的X射线排放能够改善某些材料的分析。欧洲杯足球竞彩

The wide scope of options with the Nikon Metrology system makes it a flexible tool for use across quality laboratories, production facilities and research departments, which is useful as other departments at the university will use the equipment, including DTU Compute, DTU Mechanics and DTU Physics.

到目前为止，该系统已经提供了有关细胞中孔隙分数，孔形和连通性以及材料和粒径之间的界面区域的有用信息。欧洲杯足球竞彩它也已用于研究电池的内部3D结构，并跟踪衰老周期期间和之后可能的变化。

Motorised FID enables fast scans for in-situ measurements.

With over 25 years of expertise, CT specialists at Nikon Metrology have developed and manufactured complete systems incorporating proprietary microfocus X-ray sources, high precision manipulators programmable in five axes, and fast acquisition and reconstruction software.

XT H 225 ST带有电动FID（焦点到成像器距离），这意味着检测器可以更接近源。较短的FID意味着X射线通量增加，减少成像暴露和扫描时间。DTU Energy利用了ST模型的高通量来促进更快的扫描，以进行原位测量。

购买尼康系统的动机是225 kV的微量源，最小斑点大小为3 µm，能够扫描包含重元素和较大样品的密集材料，例如电池，太阳能电池和燃料 /电气电池。欧洲杯足球竞彩
