FY13 LDRD Annual Report About the Cover Theoretical studies of improvised explosives are rare, and their experimental study is expensive and technically challenging, but a necessary part of countering today’s threats to national and international security. Principal investigator Sorin Bastea and his team developed important experimental data and simulations for characterizing and modeling the detonation behavior of explosives in the Laboratory Directed Research and Development project, “Detonation Performance of Improvised Explosives via Reactive Flow Simulations and Diamond Anvil Experiments” (11-ERD- 067). Project results may enable development of ultrafast methods for assessing sensitivity and perhaps even performance in energetic formulations, and could additionally open new avenues for the shock synthesis of materials. Researchers determined that shock wave excitation enables the observation of chemical kinetics in a very small volume, where the rate of heating is limited only by the transit time of the shock wave through the volume. Eectively, this is in situ chemistry in a very small beaker. The research was recently featured as the cover story in the scientic journal, Journal of Physical Chemistry A. The simulation of ultrafast shock initiation of exothermic chemistry in hydrogen peroxide shown here was provided by Liam Krauss of the Livermore Computing visualization team, which specializes in multimedia presentation of scientic results obtained through high-performance computing.

Our ongoing investments in LDRD continue to deliver long-term rewards for the Laboratory and the nation, supporting the full spectrum of national security interests encompassed by the missions of the Laboratory, the Department of Energy, and the National Nuclear Security Administration. Many of Livermore’s programs trace their roots to research thrusts that began under LDRD sponsorship. By keeping the Laboratory at the forefront of science and technology, maintaining our core competencies, building new capabilities, and reaching beyond the immediate challenges toward the future, the LDRD Program enables us to fulll our national security mission in an evolving global context. The LDRD Program is the largest single source of internal investment in our future, and for scal year 2013, the LDRD budget of $83.2 million supported 152 projects. These William H. Goldstein, Director projects were selected through an extensive peer-review process to ensure the highest scientic quality and mission relevance. The LDRD projects are consistent with the Laboratory’s strategic plan and have impact on the Laboratory in four distinct ways: • Attracting and retaining the best and the brightest workforce by conducting world-class science, technology, and engineering • Maintaining our competency in those core areas where our missions mandate that we must be the best, and evolving these competencies as our missions change • These core competency areas are consistent with the science, technology, and engineering foundations as dened in the strategic plan • Developing programs in strategic focus areas, guided by the strategic plan, where we have chosen to build or expand our inuence • Looking beyond the immediate challenges to future opportunities The LDRD Program is a success story. Our projects continue to win national recognition for excellence through prestigious awards, papers published in peer-reviewed journals, and patents granted. With its reputation for sponsoring innovative projects, the LDRD Program is not only a major vehicle for attracting and retaining the best and the brightest technical sta, but for establishing collaborations with universities, industry, and other scientic and research institutions. By keeping the Laboratory at the forefront of science and technology, the LDRD Program enables us to meet our mission challenges, especially those of national security in an evolving global context. ii LAWRENCE LIVERMORE NATIONAL LABORATORY Contents Overview About Lawrence Livermore National Laboratory .................................................................................................................................................................2 About Laboratory Directed Research and Development...................................................................................................................................................2 About the FY2012 Laboratory Directed Research and Development Annual Report..................................................................................................3 Highlights of Accomplishments for the Fiscal Year...............................................................................................................................................................4 Awards and Recognition.............................................................................................................................................................................................................. 15 Program Mission............................................................................................................................................................................................................................. 26 Program Structure.......................................................................................................................................................................................................................... 28 Program Metrics.............................................................................................................................................................................................................................. 34 Advanced Sensors and Instrumentation Quantication of Carbon-14 by Optical Spectrometry, Ted Ognibene (11-ERD-044)........................................................................................... 38 Ultrafast, Sensitive Gamma and Neutron Detectors, Corey Bennett (11-ERD-052) ............................................................................................... 39 Resonantly Detected Photo-Acoustic Raman Spectroscopy as a New Analytical Method and Micro-Volume Probe, Jerry Carter (11-ERD-061)............................................................................................................................................................................................................ 41 A New Approach for Reducing Uncertainty in Biospheric Carbon Dioxide Flux, Sonia Wharton (12-ERD-043) ......................................... 43 Sub-Wavelength Plasmon Laser, Tiziana Bond (12-ERD-065)......................................................................................................................................... 46 High-Precision Test of the Gravitational Inverse-Square Law with an Atom Interferometer, Stephen Libby (12-LW-009).....................

  • Part I: Introduction
    Part I: Introduction “Perhaps the sentiments contained in the following pages are not yet sufficiently fashionable to procure them general favor; a long habit of not thinking a thing wrong gives it a superficial appearance of being right, and raises at first a formidable outcry in defense of custom. But the tumult soon subsides. Time makes more converts than reason.” -Thomas Paine, Common Sense (1776) “For my part, whatever anguish of spirit it may cost, I am willing to know the whole truth; to know the worst and provide for it.” -Patrick Henry (1776) “I am aware that many object to the severity of my language; but is there not cause for severity? I will be as harsh as truth. On this subject I do not wish to think, or speak, or write, with moderation. No! No! Tell a man whose house is on fire to give a moderate alarm; tell him to moderately rescue his wife from the hands of the ravisher; tell the mother to gradually extricate her babe from the fire into which it has fallen -- but urge me not to use moderation in a cause like the present. The apathy of the people is enough to make every statue leap from its pedestal, and to hasten the resurrection of the dead.” -William Lloyd Garrison, The Liberator (1831) “Gas is running low . .” -Amelia Earhart (July 2, 1937) 1 2 Dear Reader, Civilization as we know it is coming to an end soon. This is not the wacky proclamation of a doomsday cult, apocalypse bible prophecy sect, or conspiracy theory society.

An organic acid (acetic acid, CH3COOH) has been chosen as the catalyst. The study has three objectives: first, using three different weights of MgH2 react with aqueous solution of acid for the hydrogen generation experiments. Secondly, utilizing acetic acid as the catalyst accelerates hydrogen generation. Third, emphasizing the combination of the three operating conditions (the weight of MgH2, the concentration of acetic acid, and the varying temperature) influence the amount of hydrogen generation.

There is compelling evidence to conclude that SCC is assisted, at least in part, by hydrogen embrittlement. This paper reviews the thermodynamics of the Mg-H system and the kinetics of hydrogen transport. Aspects of magnesium corrosion relevant to hydrogen absorption are also discussed. Crack growth mechanisms based on delayed hydride cracking, hydrogen adsorption dislocation emission, hydrogen enhanced decohesion, and hydrogen enhanced localized plasticity have been proposed and evidence for each of them is reviewed herein. © 2013 The Electrochemical Society.

The present article deals with the electrochemical and optical properties of Mg alloy hydrides. Electrochemical hydrogenation, compared to conventional gas phase hydrogen loading, provides precise control with only moderate reaction conditions. Interestingly, the alloy composition determines the crystallographic nature of the metal- hydride: a structural change is induced from rutile to fluorite at 80 at.% of Mg in Mg-TM alloy, with ensuing improved hydrogen mobility and storage capacity. So far, 6 wt.% (equivalent to 1600 mAh/g) of reversibly stored hydrogen in MgyTM(1-y)Hx (TM: Sc, Ti) has been reported. Thin film forms of these metal-hydrides reveal interesting electrochromic properties as a function of hydrogen content.
