The Method of Manufactured Solutions (MMS) is used to evaluate the Material Point Method (MPM) implemented in CTH, i.e. Markers. MMS is a verification approach in which a desired deformation field is prescribed and the required forcing function to achieve the prescribed deformation is determined analytically. The calc…
Significance and Use 5.1 These test methods are suitable for quality control, as specification tests, and for research. The acid and alkalinity numbers indicate the extent of a reaction with acids. The results are measures of batch-to-batch uniformity an
Significance and Use 4.1 Composite materials consist by definition of a reinforcement phase in a matrix phase. In addition, carbon-carbon composites often contain measurable porosity which interacts with the reinforcement and matrix. The composition and
Das ansteigende Anforderungsprofil an Schneidwerkzeuge macht die Entwicklung von neuartigen Hartstoffschichten bezüglich Härte, thermischer Stabilität, Zähigkeit, tribologischer Eigenschaften, Verschleiß-, Korrosions- und Oxidationsbeständigkeit erforderlich. CrN ist für seine große Härte, Verschleiß- und Oxidationsbe…
This work developed the capability for pre-compressing targets for Hugoniot measurements utilizing gas gun driven flyer plates. Initial condition control, such as pre-compression, allows access to states off the principal Hugoniot and in the case of highly compressible materials, the locus of shock states may be well…
Abstract : The US Army Research Laboratory evaluated the ballistic performance of aluminum alloys (AAs) 7056-T761, 7056-T751, and 7056-T721 produced by Constellium. Ballistic evaluation was performed using armor-piercing and fragment-simulating projectiles to determine the V50 ballistic-protection limit (V50) for vari…
Palm Oil Mill Effluent (POME) generated as by-product during clarification and purification process to produce Crude Palm Oil (CPO), contains harmful heavy metals, high Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD) and mineral contents such as Nitrogen, Phosphorous which can cause severe pollution to t…
The International Atomic Energy Agency (IAEA) continues to expand its use of unattended measurement systems. An increasing number of systems and an expanding family of instruments create challenges in terms of deployment efficiency and the implementation of data authentication measures. In collaboration with the IAEA,…
Modified polysaccharides such as starch and cellulose play important role in the polymer research because they are from natural resources and biodegradable. The main objective of this study was to prepare the hydrogels from modified sago starch and chitosan which were then applied as metal scavenger for lead (Pb), cop…
Telah dilakukan pembuatan komposit Al/SiO2 melalui metode metalurgi serbuk dengan menggunakan Aluminium komersial produk Merk-Germany sebagai matrik yang digabungkan dengan nano silika (SiO2) yang diperoleh dari hasil sintesis pasir Bancar Tuban melalui metode koopresipitasi. Fabrikasi komposit dilakukan dengan metode…
The objective of this experimental project is to demonstrate that waste streams generated during the production of Mo99 by the SHINE Medical Technologies (SHINE) process can be immobilized in cement-based grouted waste forms having physical, chemical, and radiological stabilities that meet regulatory requirements for…
There are increasing interests to alternate the microstructure and hence the properties of steels that are applied in various environment conditions using a work-efficient and energy-saving manner. The desirable microstructure evolution is often not achievable by means of conventional thermo-mechanical processing and…
Η εργασία στοχεύει στην υπολογιστική και πειραματική διερεύνηση της επίδρασης της κυκλικής διακύμανσης της καύσης σε κινητήρες, στο σχηματισμό ρύπων. Έμφαση δίνεται στις εκπομπές οξειδίων του αζώτου (NOx). Στο πλαίσιο αυτό, η παρούσα διδακτορική διατριβή συμβάλλει σε μια ερευνητική περιοχή που λίγο έχει μελετηθεί, μέσ…

This report represents the culmination of a four-year research project that was part of the Instrumentation and Control and Human Machine Interface subprogram of the DOE Advanced Reactor Technologies program.
Rattlesnake is a MOOSE-based radiation transport application developed at INL to support modern multi-physics simulations. At the beginning of the last year, Rattlesnake was able to perform steady-state, transient and eigenvalue calculations for the multigroup radiation transport equations. Various discretization sche…
In this work, cellulose-based electro and ionic conductive composites were developed for application in cellulose based printed electronics. Electroconductive inks were successfully formulated for screen-printing using carbon fibers (CFs) and multi-walled carbon nanotubes (MWCNTs) as conductive functional material and…
For this Exploratory Express LDRD we investigated the use photoelectrochemical etching to demonstrate GaN quantum wires with a diameter of less than 10 nm.Although GaN nanowires with much larger sizes (200 nm -2 microns) have been demonstrated by a number of techniques, quantum wires are much more difficult to realize…
The Organization for Economic Cooperation and Development /Nuclear Energy Agency (OECD/NEA) Nuclear Science Committee approved the formation of an Expert Group on Accident Tolerant Fuel (ATF) for LWRs (EGATFL) in 2014. Chaired by Kemal Pasamehmetoglu, INL Associate Laboratory Director for Nuclear Science and Technolog…
BISON and MARMOT are two codes under development at the Idaho National Laboratory for engineering scale and lower length scale fuel performance modeling. It is desired to add capabilities for fast reactor applications to these codes. The fast reactor fuel types under consideration are metal (U-Pu-Zr) and oxide (MOX).…
