Production of 89Zr serves as a crucial preliminary step for exploring Zr-chelates, determining their stability constants, and advancing radiolabeling methodologies for monoclonal antibody based theranostics. 89Zr is typically produced by the irradiation of natural yttrium targets, a process extensively documented in scientific literature. Two primary methods are employed: the 89Y(p,n)89Zr...
This paper synthesizes various works Wang tiles up to this point, including: the reduction from the Halting Problem to Wang Tiling Problem and notions around various aspects of periodicity, including minimal period, aperiodicity, and axis-aligned periodicity. Additionally it includes new work, including: a proof that a tiling can be periodic...
The continued long-term use of fossil fuels as a primary energy source has resulted in dramatic increases in greenhouse gas emissions and the associated concerns of climate change and environmental pollution. A key strategy to circumvent these issues is a global shift away from fossil fuels toward renewable energy sources....
Additive manufacturing has become a promising method for the fabrication of inexpensive, green, flexible sensors and electronics. Printed electronics on low- temperature substrates are very appealing for the flexible hybrid electronics market for their use in disposable and biocompatible electronic applications and in areas like packaging, wearables, and consumer electronics....
Heterogeneous catalysis modulates the rate and selectivity of reaction processes by
stabilizing a series of intermediate states on solid surfaces, facilitating the production
of many commodity chemicals modern society relies upon. Conventional, thermal
catalytic processes—conducted at elevated temperatures and pressures—source
thermal, mechanical, and chemical potential energy from carbon-hydrogen bonds—
combustion...
Nickel (Ni)-based alloys with a high chromium (Cr) content are frequently employed in applications where elevated temperatures and/or corrosive environments are present due to their excellent corrosion resistance and mechanical properties. However, a gap exists around the formation, and kinetics of long-range order (LRO) Ni2Cr phase in both model binary...
The monolithic (plate type) Uranium 10 wt.\% Molybdenum (U-10Mo) fuel system is promising for a variety of applications, most notably for the replacement of highly enriched uranium (HEU) fuels with low enriched uranium (LEU) fuel in United State High Performance Research Reactors (U.S. HPRRs).
Phase transformations and secondary phase formation...
Globally rising anthropogenic CO₂ emissions have resulted in the increased prevalence of ocean acidification (OA) which has the potential to impact shell-forming organisms. On geologic timescales, the largest contributor to atmospheric CO₂ was volcanoes, counterbalanced by weathering and erosion, but due to increased anthropogenic emissions, these processes alone can no...
Iterative algorithms are simple yet efficient in solving large-scale optimization problems in practice. With a surge in the amount of data in past decades, these methods have become increasingly important in many application areas including matrix/tensor recovery, deep learning, data mining, and reinforcement learning. To optimize or improve iterative algorithms,...
Metallic glasses (MGs), also called amorphous metals, are metals or metallic alloys trapped in a disordered glassy state. Their amorphous nature and absence of features such as crystal lattices and defects (dislocations, grain boundaries etc.) endows them with a host of properties that far surpass those of common crystalline materials....
