The scientific and engineering investigations and understanding of ultra-small objects, known as nano-materials, is not only revolutionizing critical fields such as medicine, personal electronics, and national security, but it is also sharpening the understanding of how the Earth works. The air one breaths, the soil in which crops are planted, the metals from minerals that build industries, and the contaminants that can profoundly harm one (from arsenic to dangerous bacteria), are all related to and/or influenced by the vast store of nano-materials that make up key portions of the planet. These nano-materials must be studied and understood, despite great difficulty due to their minute size, to safely and efficiently clean the air, purify water, and allow the responsible use of Earth's vast store of life-sustaining resources. The Virginia Tech National Center for Earth and Environmental Nanotechnology Infrastructure (VT NCE2NI) will greatly accelerate the progress that Earth scientists and engineers have made in studying, understanding, explaining, and utilizing Earth for the well-being of all. In addition, new types of environmental sensors and detectors based on rapidly emerging nanotechnologies, for example to detect harmful living and non-living contaminants in air, water, and soil, will clearly be a major benefit to society. VT NCE2NI users will consist of far more than professional academics and their advanced research students. Users will also come from private and publicly-held companies, as well as students from high schools, community colleges, liberal arts colleges, and key minority-serving universities. VT NCE2NI provides an NNCI site to specifically support researchers who work with nanoscience- and nanotechnology-related aspects of the Earth and environmental sciences/engineering at local, regional, and global scales, including the land, atmospheric, water, and biological components of these fields. The national presence of VT NCE2NI is significantly enhanced by a close partnership with the Environmental Molecular Sciences Laboratory (EMSL) at Pacific Northwest National Laboratory (PNNL). NNCI geo- and environmental science/engineering users have access to both the Virginia Tech and EMSL/PNNL sites depending on specific technical needs and geographic considerations. VT NCE2NI consists of (i) the 15,000 sq. ft. Nanoscale Characterization and Fabrication Laboratory (NCFL) that houses a broad array of high-end, state-of-the-art electron-, ion-, and X-ray-based characterization tools, sample preparation laboratories, as well as meeting space and ample office space for visitors; and (ii) the 6,300 sq. ft. Virginia Tech Center for Sustainable Nanotechnology (VT SuN) which contains extensive nanomaterials synthesis facilities and knowhow (in aqueous, soil/solid media, and atmospheric environments), characterization tools, and experimentation/reactor systems, plus meeting rooms and additional office space for visitors. VT NCE2NI also provides broader impact initiatives including substantial funding for students from key minority-serving institutions, and outreach programs with community colleges and four-year liberal arts colleges. The overall contribution of this NNCI site will be to accelerate the growth of a field that is revolutionizing the understanding of several broad aspects of Earth and environmental sciences and engineering.

对超小物体（即纳米材料）的科学和工程研究和理解不仅正在彻底改变医学、个人电子产品和国家安全等关键领域，而且还加深了对地球如何运作的理解。 人们呼吸的空气、种植农作物的土壤、工业矿物中的金属，以及对人造成严重伤害的污染物（从砷到危险细菌），都与构成地球关键部分的大量纳米材料有关和/或受其影响。 尽管由于尺寸微小而存在很大困难，但必须研究和理解这些纳米材料，以安全有效地清洁空气、净化水并负责任地使用地球上蕴藏的大量生命维持资源。 弗吉尼亚理工大学国家地球与环境纳米技术基础设施中心（VT NCE2NI）将极大地加速地球科学家和工程师在研究、理解、解释和利用地球以造福所有人方面所取得的进展。 此外，基于快速新兴的纳米技术的新型环境传感器和探测器，例如用于检测空气、水和土壤中有害的生物和非生物污染物，显然将为社会带来重大利益。 VT NCE2NI 用户将不仅仅包括专业学者及其高级研究生。 用户还将来自私营和上市公司，以及来自高中、社区学院、文理学院和重点少数族裔大学的学生。 VT NCE2NI 提供了一个 NNCI 网站，专门支持在地方、区域和全球范围内研究地球和环境科学/工程的纳米科学和纳米技术相关方面的研究人员，包括这些领域的土地、大气、水和生物组成部分。 通过与西北太平洋国家实验室 (PNNL) 环境分子科学实验室 (EMSL) 的密切合作，VT NCE2NI 在全国的影响力得到显着增强。 NNCI 地理和环境科学/工程用户可以根据特定的技术需求和地理考虑因素访问弗吉尼亚理工大学和 EMSL/PNNL 站点。 VT NCE2NI 包括 (i) 15,000 平方英尺的纳米表征和制造实验室 (NCFL)，该实验室拥有各种高端、最先进的基于电子、离子和 X 射线的表征工具、样品制备实验室以及供访客使用的会议空间和充足的办公空间； (ii) 占地 6,300 平方英尺的弗吉尼亚理工大学可持续纳米技术中心 (VT SuN)，其中包含广泛的纳米材料合成设施和专业知识（在水、土壤/固体介质和大气环境中）、表征工具和实验/反应器系统，以及供访客使用的会议室和额外办公空间。 VT NCE2NI 还提供更广泛的影响力举措，包括为来自主要少数族裔服务机构的学生提供大量资金，以及与社区学院和四年制文理学院的外展计划。 该 NNCI 网站的总体贡献将是加速这一领域的发展，该领域正在彻底改变对地球和环境科学与工程几个广泛方面的理解。
