Electron and Scanning Probe Microscopies (EM and SPM) are critical techniques for researchers involved in materials science. Scanning electron and atomic force microscopes, which allow the surfaces of materials to be probed, are more widely available both in academia and industry due to their lower operational costs. Transmission electron microscopes (TEM), which allow the imaging of both the external and internal structure of materials at resolutions at least an order of magnitude better than SEMs, are generally more expensive and hence less widely available. TEMs are available in numerous configurations dependent on the specific nature of the materials under investigation. Recent advances in instrument and detector design have dramatically improved the analytical capabilities of TEMs such that they are essential instruments to support pioneering studies on nanostructured materials.Understanding how chemically derived processes control the construction and organization of matter across nanoscopic length scales is of critical importance in diverse areas of materials research. Although many areas of nanoscience are burgeoning, there remains an urgent need to develop coherent and robust strategies towards the synthetic construction of functional nano-objects and nanostructures. In particular, the systematic design of nanoscale architectures from programmable components that collectively produce integrated functions has great transformative potential in key emerging fields such as bioelectronics, energy storage, sensing, nanoplasmonics, drug delivery and high performance green catalysis. The requested field emission gun analytical transmission electron microscope [FEG-ATEM] will provide the sub nm resolution demanded to fill our current analytical information gap so that scientific ambitions in these research areas are not constrained. The instrument forms part of a strategic investment in advanced microscopy provision at Bristol, and is the centrepiece of ambitions for an internationally competitive materials characterization facility befitting the world-leading research it underpins.

电子和扫描探针显微镜（EM和SPM）是材料科学研究人员的关键技术。扫描电子显微镜和原子力显微镜允许探测材料表面，由于其较低的运营成本，在学术界和工业界都更广泛地使用。透射电子显微镜（TEM）允许以比SEM好至少一个数量级的分辨率对材料的外部和内部结构进行成像，其通常更昂贵，因此不太广泛可用。TEM有多种配置，这取决于所研究材料的具体性质。在仪器和检测器设计的最新进展显着提高了TEM的分析能力，使他们成为必不可少的工具，以支持开拓性的研究nanostructured materials.Understanding化学衍生过程如何控制建设和组织的物质在纳米尺度的长度尺度是至关重要的，在不同领域的材料研究。虽然纳米科学的许多领域正在蓬勃发展，但仍然迫切需要制定一致和强大的战略，以合成功能纳米物体和纳米结构。特别是，从可编程组件，共同产生集成功能的纳米级架构的系统设计，在关键的新兴领域，如生物电子学，能量存储，传感，纳米等离子体，药物输送和高性能绿色催化具有巨大的变革潜力。所要求的场发射枪分析透射电子显微镜[FEG-ATEM]将提供所需的亚纳米分辨率，以填补我们目前的分析信息空白，使这些研究领域的科学野心不受限制。该仪器是布里斯托先进显微镜供应战略投资的一部分，是具有国际竞争力的材料表征设施的核心，适合其所支持的世界领先的研究。
