Radiation Surface Science and Engineering Lab

Prof. Allain collaborates with the Planetary Science Institute’s TREX project exploring how radiation impacts the surfaces of moons and asteroids

Posted on by

Professor Allain’s RSSEL group will examine surfaces of fine-grained bodies from asteroids and surrogate materials under simulated radiation exposure conditions created in IGNIS facility to decipher space weathering effects. Prof. Allain will examine lunar samples collected during the U.S. Apollo missions and surrogate minerals such as olivine, as well as samples from an asteroid mission the Japanese conducted in 2007 of the near-earth asteroid Itokawa.

The Planetary Science Institute has been awarded $5.5 million by NASA to be a research node of the Solar System Exploration Research Virtual Institute (SSERVI) to advance basic and applied research for lunar and planetary science, and advance human exploration of the solar system. The node, known as the TREX toolbox emphasizes new areas that have not been well-studied. These include probing the properties of fine-grained particles at ultraviolet (UV) wavelengths.

Share the Vision will preview a pipeline of emerging technologies through research & start-up presentations featuring 24 leading innovators and entrepreneurs from the University of Illinois at Urbana-Champaign and partner institutions.

This year’s event will focus on technologies at the intersection of engineering and medicine in four areas: Emerging Drug Discoveries; Targeted Bio-Tools & Real Time Diagnostics; Intersection of Informatics & Healthcare; and Body Visualization & Engineering.

Simulation of GaSb surface nanopatterning by Directed Irradiation Synthesis (DIS) highlighted in Blue Waters NCSA 2016 Report

Posted on by

RSSEL’s Multi-scale Computational Irradiation Surface Science team was invited to present highlights from their research that leveraged Blue Waters petascale supercomputer at the National Center for Supercomputing Applications (NCSA).

Massive-scale atomistic simulations used while developing directed irradiation synthesis of ordered nanodots and other nanostructures are necessary to address knowledge gaps in existing theories of nanopattern formation and growth.

The work completed involved conducting MD simulations of 3 million atoms for nearly 50 million time steps. On a conventional supercomputing cluster this would take multiple years to complete. Production runs on Blue Waters were able to simulate up to 10 million time steps on 128 nodes in just 48 hours, allowing the majority of the production runs to be completed in less than two months actual time. The 2016 Blue Waters report highlights RSSEL’s work on page 96, and complete research results were published in the journal Nucl. Instrum. Methods Phys. B in April 2017: Massive-scale molecular dynamics of ion-irradiated III–V compound semiconductors at the onset of nanopatterning

Prof. Allain recognized with Dean’s Award for Excellence in Research

Posted on by

Professor Allain has received the 2017 College of Engineering Dean’s Award for Excellence in Research for his work unifying concepts from nanotechnology, nuclear engineering and materials science.

NPRE Department Head Jim Stubbins highlighted Prof. Allain’s research group for its impact forging new fundamental and applied research directions in emergent areas of material surfaces and interfaces exposed to extreme environments, as well as pioneering the use of in-situ and in-operando surface diagnosis and directed irradiation synthesis, complemented with multi-scale modeling developed to support these research themes.
