Silk-based Biomaterials for Wound Care and Tissue Regeneration
For most individuals, wound healing is a highly organized, straightforward process. However, there are instances where external intervention becomes necessary to support the body’s innate healing mechanism. In this thesis, ... -
On the creep behaviour of Ni based solid solution alloys from binary to quaternary
On the creep behavior of Ni based solid solution alloys from binary to quaternary A power-law relationship between the steady state strain rate (𝜀̇) and imposed stress (σ) is well established so that the 𝜀̇∝𝜎^𝑛, at a ... -
Structure-Property Correlation in Additively Manufactured High-Temperature Materials: Insights from Nickel-Based Superalloy IN718 & Nickel-Based Eutectic High Entropy Alloy AlCoCrFeNi2.1
High-temperature alloys are technically very important materials that possess higher resistance toward mechanical and chemical degradation at 0.4-0.6 TM for a constant/cyclic load. These attributes make them candidate ... -
A Multiscale Study of the Thermodynamics and Kinetics of Vacancy–grain-boundary Interactions
Grain boundaries (GBs) influence many physical and mechanical properties of crystalline materials. This is primarily because of their interactions with other kinds of defects, such as point and line defects. Such interactions ... -

Study of gas-fine flow in a packed bed with an application to the ironmaking blast furnace
The iron and steelmaking industry uses coal as the primary reducing agent. The carbon that is the major component of coal is finally released into the environment as carbon dioxide. One of the effective ways to reduce the ... -
Enhancement in corrosion resistance of selected high entropy alloys by incorporation of carbon nanotubes
High entropy alloys (HEAs) have attracted considerable interest due to their remarkable structural and functional properties. HEAs generally contain 5–13 principal elements with the concentrations of each component lying ... -
Novel L12 precipitate hardened Co-base alloys
Conventional cobalt base superalloys relied on solid-solution and carbide precipitate based strengthening. They lacked high temperature (more than 800 ˚C) creep strength as compared to Ni-base superalloys which are ... -
Interfacial Engineering of Hierarchical Carbon Fiber Reinforced Epoxy Laminates for Mechanical Property Enhancement and Self-healing Ability
Carbon fiber-reinforced epoxy (CFRE) laminates have become a significant component in aircraft industries over the years due to their superior mechanical and highly tunable properties. However, the interfacial area between ... -
Cerium Oxide-based Degradable Polymer Nanocomposites for Bone Tissue Engineering
The incidences of bone-related disorders is growing steeply worldwide because of acute trauma, diseases related to aging, and obesity. Bone has a natural regenerative capacity to repair and regenerate fractures and small ... -
Correlation Between Microstructure and Corrosion Properties of Electrodeposited Nickel and Zinc Based Coatings
Conventional metallic coatings such as Ni and Zn are extensively used in corrosion protection applications. In most studies on the corrosion behavior of metallic coatings, the emphasis is on correlating morphology and ... -
