Engineered nanoparticles (NPs) are materials with unique properties that originate from having at least one spatial dimension less than 100 nm. NPs are incorporated into manufactured products and have various applications in daily life including personal care products, textiles,…
We investigated the mechanical properties, such as fracture toughness (KIc), fracture energy (GIc), ultimate tensile strength (UTS), Young¡¦s modulus (E), and fatigue crack propagation rate (FCPR) of epoxy-matrix composites with different weight fractions of carbon-based fillers…
I performed a systematic study on Co/Sb superlattices varying Antimony (Sb) thickness keeping Cobalt (Co) thickness constant at 1 nm. Here I studied the decay of resistivity of those samples. To make those samples I deposited 10 bilayers of Co and Sb at 500° C on <100> face of s…
The band structure and carrier dynamics of GaAs, GaAs/GaP and InP semiconductor nanowires is explored using a variety of optical spectroscopy techniques including two newly developed techniques called Photomodulated and Transient Rayleigh scattering spectroscopy. The stress and …
When an atomic/molecular system controlled by an external field (to imprint information on it, such as preparing a qubit), is brought near a plasmonic nanostructure, the control problem changes. On one hand, the field experienced by the atom is modified due to the plasmon effect…
The tri-gate FET has been hailed as the biggest breakthrough in transistor technology in the last 20 years. The increase in device performance (faster switching, less delay, improved short channel effects, etc.) coupled with the reduction in device size, would allow for huge gai…
Using equilibrium molecular dynamics simulations, an analysis of the key thermophysical properties critical to heat transfer processes is performed. Replication of thermal conductivity and shear viscosity observations found in experimental investigations were performed using a t…
Layered materials like graphite, tungsten disulfide (WS2 ) and molybdenum disulfide (MoS2 ) are known for their ability to reduce friction and wear either as a pure solid lubricant or as additive for liquid lubricants. The synthesis of closed-cage inorganic nanostructures, made …
Resonant coupling of localized surface plasmon resonances (LSPRs) in noble metallic nanostructures to incident radiation and the related subject of localized behavior of electromagnetic waves are currently of great interest due to their potential application to sensors, biochemi…
Sustained stimulation of sensory organs results in adaptation of the neuronal response along the sensory pathway. Whether or not cortical adaptation affects equally excitatory and inhibitory inputs is poorly understood. This question was examined using patch recordings of neuron…
Carbon nanotubes have unique electronic, mechanical, optical and thermal properties, which make them ideal candidates as building blocks in nano-electronic and electromechanical systems. However, their organization into well-defined geometries and arrays on surfaces remains a cr…
This research work explored the growth of silicon nanowires with titanium catalysts and atmospheric pressure chemical vapor deposition (APCVD). A silicon nanowire is a one-dimensional structure having a diameter on the order of a few nanometers to hundreds of nanometers. Dependi…
The theoretical calculation of the electronic structure of any constituent materials is the first step towards the interpretation and understanding of the experimental data and reliable device design. This is essentially true for nanoscale devices where the atomistic granularity…
Lithium – Sulfur (Li-S) batteries have received much attention and considered as a promising candidate for next generation energy storage devices because of their high theoretical energy density (≈2600 Wh kg‒1) and environmental friendliness. However, the uncontrollable growth o…
In this work, the radiation dose enhancement is studied using a novel method and material that has not been widely investigated, at the time of this publication. Radiation dose enhancement is a useful technique in the field of radiation therapy, especially when dealing with radi…
Topological photonics is the study of how the geometries and topologies of devices can be used to manipulate the behavior of photons. Many topological models exhibit edge states, a defining feature of these models, which travel around the perimeter of the lattice and are not aff…
Rapid development of wireless and internet communications requires development of new generation high frequency electronics based on new device concepts and new materials. The very high intrinsic velocity of charge carriers in graphene makes it promising new channel material for…
Since their discovery, tight oil and gas reservoirs have been plagued by low ultimate production numbers that rarely surpass 10%. One of the major factors contributing to this is the incomprehension of fluid phase behavior in these reservoirs. Indeed, operators only account for …
