Hjelm Presents at 13th Fall Rubber Colloquium

Rex Hjelm, an NMC Research Scientist, presented his work on "Interrelation of Molecule Scale Polymer Melt Response to Shear and Rheology in the Non-linear Rheological Domain” at the 2018 Fall Rubber Colloquium in Hanover, Germany.

This year marked the 13th Fall Rubber Colloquium, held from November 6-9, 2018. The conference highlights the latest scientific concepts and advanced processing techniques in rubber and polymer science and technology. Conference topics included materials, reinforcement, vulcanization, processing, aging, analyzsis, environment, tires, physics and simulation.

Hjelm's work looks at the problem of understanding the relationship between the bulk rheological properties of entangled polymeric liquids and the polymer molecular architecuure, which is one of the most interesting and important problems in polymer science. This paper focuses on the non-linear phenomenon of shear thinning and the molecular level response of polymers.

Corcoran Presents at Advanced Bioeconomy Leadership Conference

Dr. Alina Corcoran, NMC Researcher and LANL Guest Scientist, presented at the Advanced Bioeconomy Leadership Conference (ABLC) Global 2018 last week. This conference was held November 6-9, 2018 in San Francisco, CA. The ABLC Global is a connected series of 17 conferences and forums on the most important issues in the bioeconomy right now.

Corcoran's presentation was on Transforming Challenges into Yield: Variability and the Role of Synthetic Ecology, which focused on algae's role in sustainable development, green chemistry and clean technology. See the presentation here: https://prezi.com/view/Nv9tqWe2QhinqstOzaQT/


Research at NMC to Convert Algae to Affordable Fuel

Molecular biologist Amanda Barry and a team at Los Alamos National Laboratory's Bio-energy and biome Sciences group are conducting research on a specific strain of algae in order to determine if it can be produced quickly and at low cost. If so, this algae hold potential to be a source of renewable fuel that can economically compete with fossil fuels.

This research takes place at the New Mexico Consortium's Biolab in Los Alamos. Here researchers are really focusing on algae due tot their ability to produce refinery-compatible diesel and jet fuel precursors.

If successful, this new source of renewable biofuels will reduce our dependence on fossil fuels, contribute towards clean energy solutions, and contribute to domestic job growth.

NASA Grant Awarded to Michael Denton

Michael Denton, an NMC researcher, and Lauren Blum, a scientist with NASA's Goddard Space Flight Center, have been awarded a NASA grant to study plasma structure and composition as a driver of wave growth in the inner magnetosphere.

Why is this important in space science research? Electromagnetic (EM ) waves accelerate electron particles to high energies which can cause damage to satellites. Electromagnetic Ion-Cyclotron (EMIC) waves are a specific type of EM wave that is known to cause the loss of electrons. Scientists don't fully understand this phenomenon, but are working to understand where EMIC waves occur in order to know where electrons may be lost and predict this loss in the future.

Thus, understanding EM waves is important for the prediction and mitigation of the potentially damaging environment that satellites operate in.

Recent studies of EMIC waves reveal a dependence of the waves' spatial extent on magnetic local time (MLT), wave frequency, and L shell around Earth.  Various hypotheses have been proposed to explain some of these patterns, including different sources (and spatial extents) of ion anisotropy on the day versus night side, compositional variations throughout the inner magnetosphere, or cold plasma density structure.

Denton and colleagues seek to understand how these things all tie in together. Composition, or the density of the hydrogen/oxygen/helium ions, is predicted to play a big role in growth of the waves. This work aims to link the composition changes up with the patterns seen in the waves, and subsequently in the electron distributions. This is something that has not been explored yet.

Multipoint measurements in the inner magnetosphere, such as from satellite missions like the NASA Van Allen Probes, can allow the spatial and temporal evolution of various particle populations and wave modes to be better understood.


Panagiotis Lymperopoulos: Phytochrome and Phytohormones: Working in Tandem for Plant Growth and Development

July 28, 2018.  New Mexico Consortium Biolab researchers, Panagiotis Lymperopoulos, Joseph Msanne and  Roel Rabara, have recently published their work "Phytochrome and Phytohormones: Working in Tandem for Plant Growth and Development" in the July 2018 issues of Frontiers in Plant Science, section Plant Physiology.

This publication is a review that presents a representative regulatory model, highlights the successes achieved in employing novel strategies to dissect the levels of interaction and provide perspective for future research on phytochrome-phytohormones relationships toward facilitating plant growth, development, and function under abiotic-biotic stresses.
