Introduction to the Workshop (Room CAS 213, Boston University)

Coffee served from 7:30am to 9:00am in the lobby area of the College of Arts and Science

8:00-8:15 Registration, informal meet and greet

8:15-8:30 Welcome! Workshop Goals. Introductory Slides

  • Introduce the geoscience community to new advances and opportunities to do research in nanoscience.
  • Help participants stay current with data, tools, services, and research related to nanogeoscience and nanoenvironmental science.
  • Showcase modern instruments, software, and related methods used to sample, analyze, and characterize nanomaterials in Earth and Environmental Sciences.
  • Address the "big science questions" related to nanoscience: nanomaterials in the Earth system, impacts on biogeochemical processes, characterization of nanomaterials and their chemical properties at the nanoscale, impacts of nanomaterials (natural and incidental) on the environment and human health.
  • Consider ways to effectively teach about "what can't be seen" on the nano-scale; how can we introduce nanoscience across the geoscience curriculum? How can we best train future geoscientists to be prepared to do this exciting new research?
  • Build collaborations; develop research networks to facilitate nanoscience research in the Earth and Environmental Sciences.

Part III: A Focus on Application of Nanoscience in the Earth and Environmental Sciences

(Bring your own coffee/tea from local coffee shops, or there is service later in the morning from vendors in the Union)

8:00-8:15 Informal "Networking" Set Up Demonstrations (George Sherman Union, small ballroom, upstairs)

8:15-8:30 Welcome Day 2; Reflection and Overview

8:30-11:30 "Share Fair" Demonstrations

This session is designed to provide maximum opportunities for participants to interact with experts in a variety of sub-disciplines of nanoscience. Think of this as a computer-enabled poster session. At the start of this session, we will assemble into small groups in order to distribute the workshop attendees among the demonstrations made by our presenters, which include a number of invited corporate vendors. Then, participants will a) have the opportunity to talk about their own methodologies to get feedback on their research and to build collaborations; or, b) attend additional demonstrations of particular interest to get first hand, practical advice on how to engage a particular line of research. We will "platoon" the demonstrations half way through the morning so that presenters will have the chance to interact with other presenters or corporate vendors at their demonstration sites. The goal is to optimize interactions among the participants and corporate vendors, and to be sure that all participants leave the workshop with practical advice about how to continue their nanoscience research.

Demonstrations will include:
  • TOFWERK, Olga Borovinskaya-- Time-of-flight ICP-MS, single particle NP analysis
  • Perkin Elmer, Chady Stephan -- Q-ICP-MS, single NP/cell analysis
  • Cameca Nu--Phil Shaw, will be demonstrating the Cameca Atomic Probe Tomography and the Nu ICP-MS instruments.
  • Manuel Caraballo (University of Chile); TBD
  • Cynthia Hall (West Chester University, PA)TBD
  • Thilo Hofmann (University of Vienna/Duke Univ)--Pitfalls on Nanoparticle Characterisation -- a discussion of practical tips of "do's" and "dont's" in working with nanoparticles.
  • Bojeong Kim (Temple Univ.)--The majority of metal and metal oxide nanoparticles in use today are already present in nature as naturally-occurring nanoparticles. Therefore, in this presentation, the application and method development of analytical transmission electron microscopy and laser scanning confocal microscopy to study the environmental behavior and fate of engineered nanoparticles that have natural analogs will be discussed in depth by using both field- and laboratory-scale studies with examples of aluminum oxide, titanium dioxide, zinc oxide and silver nanoparticles.
  • Amy Gartner, (USGS)--Nanoparticles and colloids in hydrothermal black smoke. The rapid mixing of hydrothermal fluids and seawater results in the formation of 'black smoke,' or the precipitation of minerals that range in size from nano- to macro-scale. Controls on this precipitation constrain mineral emplacement, whether in hydrothermal chimneys, metalliferous sediments, or the distal hydrothermal vent plume. Although broad similarities exist, and sulfides are the most important component of hydrothermal 'black smoke,' the specific mineralogy, size and therefore reactivity of particles emitted varies between hydrothermal sites in the global ocean, and even at different sites within the same vent field. A comparison among and between sites will be presented.
  • Emily Estes, (University of Delaware)--Sampling the diversity of marine hydrothermal nanoparticles
  • Mitsu Murayama (Virginia Tech)
  • Alberto Perez-Huerta (Univ. of Alabama): Demonstration on how the analysis of Atomic Prove Tomography (APT) data is conducted from the "software point of view." Most of the data analysis is dependent on "user's choices" for peak identifications; I will have a set of blank mass spectra (m/z) and participants will have to identify peaks to find out the mineral analyzed. This is not just useful for the APT data analysis but also for any type of TOF mass spectrometry results.
  • Michael Schindler (Laurentian University, Canada )--How do you identify the best location for a focused ion beam extraction of a section in geological material?I will give tips and tricks how to identify the best and most representative location for a focused ion beam extraction of a section in geological material. For this purpose, I will show how I selected locations for FIB section extractions in two very distinct geological materials: Section I: Extraction of FIB sections from alteration rims on volcanic glass in order to understand the formation of Fe-hydroxide nanoparticles in volcanic soils. Section 2: Extraction of FIB sections from a gold-bearing hydrothermal vein in order to determine whether gold has been transported via gold nanoparticles.
  • Marc Michel (Virginia Tech)--Determining Nanoparticle Sizes Using Powder Diffraction and Small-Angle X-ray Scattering Methods
