Dear Colleagues,
We would like to bring to your attention a symposium session and a workshop on Nanogeochemistry that may interest you. Abstract submission to the session is open until February 26, 2025. The deadline for early registration for the workshop is May 21st , 2025.

Session 06J - Innovations in Experimental, Analytical, and Computational Techniques to Investigate the Nanoscale in Geochemistry and Biogeochemistry
Theme 06: Frontiers in Analytical and Computational Techniques.
https://conf.goldschmidt.info/goldschmidt/2025/goldschmidt/2025/meetingapp.cgi/Session/7696

Description: Studying nanoscale particles and environments has become critical to understanding geochemical cycles in terrestrial, aquatic, and atmospheric environments. These studies can only be accomplished by recent advances in instrumentation, experimental methods, and data analysis/computation. Imaging and elemental analyses, notably through microscopy and synchrotron facilities, facilitate examination of nanoscale materials and environmental processes (e.g micro- and nanoscale sites in soil and sediments that influence redox speciation, nutrients, and biogeochemical cycles).Advances in mass spectrometry, especially ICP-MS and field-/flow-based separation, enable accurate measurements of mass and size distribution, as well as elemental, mineralogical, and/or organic composition of nanomaterials. These data are essential to understand the role of particles in (bio)geochemical cycles and the mechanisms underlying those processes. Examples of particle-modulated processes include: dispersal of indicator elements from ore deposits, soil weathering and sediment transport, climate and health impacts of atmospheric particles, and the transport and toxicological effects of anthropogenic contaminants. This session will emphasize recent innovations and adaptations in the design and application of novel methodologies applied to particles, colloids, and the (bio)geochemical processes they influence. Areas of interest include, but are not limited to:
•      state-of-the-art resources available at user facilities or individual labs to characterize and interrogate the interactions involving nanoparticles, colloids, microbes, and minerals;
•      advancements in analytical techniques aimed at accurately measuring the size and composition of geogenic, biogenic, and anthropogenic nanoscale particles including nanominerals;
•      adaptations of established techniques from other fields that advance nano-geochemical research.

Advanced Nanoparticle Analysis: Answering new questions in geochemistry | 1-DAY WORKSHOP
Sunday July 6th,  9:00-16:00
https://conf.goldschmidt.info/goldschmidt/2025/goldschmidt/2025/meetingapp.cgi/Session/7206

Description: Numerous geochemical processes involve nanoparticulate and colloidal particles. Their enumeration, size analysis, and characterization of chemical composition facilitates the study of biogeochemical cycling, contaminant transport, mineral exploration, and a host of other fields. Over the past decade, ICP-based methodologies, including single particle ICP-MS (spICP-MS) and field-flow fractionation (FFF) coupled to ICP-MS, have developed the ability to provide unique insights into these important size fractions. This workshop is directed towards geochemists and environmental scientists who use, or are interested in using these methods in their work. It will provide a forum for FFF-ICP-MS and spICP-MS experts to meet and collaboratively develop new ideas, approaches, and applications. The workshop will provide an opportunity for researchers unfamiliar with these techniques to learn the fundamentals and explore their utility for their areas of interest. Lectures will be presented by leaders in the field, covering basic concepts of the methodologies and current commercial instrumentation. The format will also include case studies of emerging geochemical applications, and advances in data processing and treatment. The workshop will conclude with 30-minute round robins of “meet the experts” for focused small group discussions. Attendees will leave with a thorough knowledge of FFF and spICP-MS that will allow them to utilize the method in their studies. Coffee and lunch will be provided.

We hope you will consider submitting an abstract to the session and hope to see you at both the session and workshop.
Regards
Jim

Liddicoat Postdoctoral Research Fellowships in Mineralogy, Materials Science and Gemology at GIA

GIA (Gemological Institute of America®) invites qualified candidates to apply for the Richard T. Liddicoat Postdoctoral Research Fellowships at its Carlsbad, California, and New York City locations. The one- to two-year fellowships encourage early career scientists to pursue full-time academic research in mineralogy, geology, physics, materials science, and other fields related to gemology – the study of diamonds, colored gemstones, pearls, and their treatment. In-house research tools include FTIR, UV-Vis-NIR absorption, Raman, photoluminescence, and EPR spectrometers, an SEM microscope equipped with EDS and CL spectroscopy and imaging, laser ablation ICP-MS, and a CVD diamond growth lab with laser cutting and polishing facilities. Fellows are expected to conduct creative, independent, publishable research and collaborate with GIA scientists, outside research institutions and universities.
The fellowship includes a competitive annual stipend ($73,000+), research funding and approved travel subsidies. Benefits include health, dental and vision, and potential reimbursement of relocation expenses.
The start date of each fellowship is flexible, but accepted candidates should begin by Jan. 31, 2026. Applicants must have received their Ph.D. in a relevant field by the start date, and preferably within the last three years.
Applications are due by May 31, 2025.
