Fe25Co25Ni25Cr25-XMoX High Entropy Alloys were fabricated in mini arc-melter and then cast into 4mm diameter cylinders by injection casting technique and 1cm diameter cylinders by water quenching technique. Heat transfer modeling during solidification of FeCoNiCr HEA was simulated. Combining X-Ray Diffraction, Optical Microscopy, Scanning Electron Microscope, Energy Dispersive X-ray analysis,...
Reverse osmosis (RO) is being increasingly used in treatment of domestic
wastewater secondary effluent for potable and non-potable reuse. Among other
foulants, dissolved biopolymers, i.e., proteins and polysaccharides, can lead to
severe fouling of RO membranes. In this study, the roles of RO membrane surface
properties in membrane fouling by...
Metallic glasses (MGs) have attracted tremendous attention because of their unique properties and potential applications in the future industry. However, it is still a mystery for people to understand the formation mechanism of the bulk MGs (BMGs). To produce BMGs, the specific composition of materials, sufficiently high cooling rate, etc.,...
Metallic glasses are attracting tremendous attention because of their fundamental significance and great potential to be used as structural or functional materials in engineering applications. Significant efforts have been devoted to studying their unique properties as well as their disordered nature. Metallic glasses possess much higher strength and elastic strain...
Spontaneous quasicrystal (QC) formation has not been observed in pure metals either in computation or in experiments (excluding epitaxial growth of thin atomic layers on a QC template). In this thesis work, dodecagonal QC (DDQC) grains are first discovered to spontaneously form during thermal devitrification of pure tantalum (Ta) metallic...
Reasoning about 3D shape of objects is important for successful computer visionapplications in robotics, 3D rendering and modeling. In this thesis, we address twoproblems { First, given an image, we generate 3D shape of the foreground object thatappears in the image. Second, we predict the class label of the input...
A characterization of the antigenic determinants (epitopes) of the glycoprotein (G) of infectious hematopoietic necrosis virus (IHNV) was made with different regions of the G gene expressed in Escherichia coli. A cDNA copy of the G gene was divided into four fragments after Taq I digestion and these fragments were...
Cubic phase Li₇La₃Zr₂O₁₂ (LLZO) is a promising solid electrolyte for all solid-state lithium-ion battery, due to its reasonable ionic conductivity, stable against metallic Li, wide chemical window, and thermal and chemical stability. The main aim of this thesis is to investigate the influences of different synthesis methods on the structure...
The global motivation for this work comes from the desire to fabricate "plastic lumber" with improved mechanical properties (particularly creep resistance) from recycled plastics and wood composites. The present studies have utilized "virgin plastics" of polystyrene (PS), an amorphous, stiff material that exhibits brittle fracture, and high density polyethylene (HDPE),...
Increasingly congested surface transportation network in urban areas and grow-ing land values make underground transportation systems more attractive for high-ways (i.e., tunnels) and metro system compared to other options [1]. An underground transportation system can preserve the land above for recreational parks, commer-cial buildings, residential homes, or other purposes while...
