In recent years, the oil and gas industry has prioritized the remediation of residual and historical soil and groundwater contamination due In part to increased public awareness and media attention on the subject. As a result, in an effort to demonstrate social accountability and environmental sustainability, there has been a significant increase In the exploration and implementation of cost-effective and environmentally-friendly approaches for remediation of contaminated sites.
Solar energy is one of the best sources of environmentally friendly reliable energy. Metamaterials is one of the subjects of nanotechnology, which applies scientific and engineering principles to make and utilize very small things things at the nanometer scale, where unique phenomena enable novel applications. How to improve the efficiency and reduce the cost of power collected by crystalline silicon solar cells with Metamaterials is a subject of great interest and also the objective of this project.
The current survival times for breast cancer patients with brain metastasis range from 2 to 16 months suggesting a strong need for improvements in their therapeutic care. Although radiation therapy is the standard of care for these patients, combination with chemotherapy has demonstrated promising therapeutic benefits. The hypothesis of this research program is based on the belief that optimizing combination of radiation and chemotherapy has the potential to significantly improve the treatment outcome for patients with breast cancers that have metastasized to the brain.
Motivated by the urgent need for clean and sustainable source of energy we propose to develop structurally and chemically controllable fuel cell catalyst layers based on ultrafine nanocomposite carbon fibre catalyst support. Manufacturing parameters will be controlled and optimized to investigate the effect of microstructure on key performance factors. Ultimately, the knowledge gained from this study will pave the way to building more efficient fuel cells. Current phase of the project involves validating our design by in-situ testing.
Most colors in nature are due to the presence of pigments or dyes. Artificial colors on different materials are produced by incorporating dyes in them. However, the brightest colors in nature, e.g. the colors of butterfly wings and peacock feathers, are generated because of the micro/nano-features on their surface. Unlike the added dyes or pigments in a material, the colors produced by surface features, also called structural colors, do not fade with sunshine and this colors are non-toxic. Laser irradiation can create structural colors on metals by an easy one-step process.
Blending carbon fillers with thermoplastic materials can lead to a significant improvement of the resulting electrical, mechanical, thermal, and gas barrier properties compared with the unfilled polymer. Graphene, the name given to a material consisting of two-dimension layers of carbon atoms arranged in a hexagonal lattice, has extraordinary properties which make possible to produce a new class of polymer nanocomposites with significantly improved properties.
Transparent electrodes (TEs) combine high optical transparency and electrical conductivity, useful in different devices such as light-emitting diodes, displays and solar cells. A highly competitive market of electronic devices, such as phones and flexible touch screens as well as a worldwide increasing demand for energy, drives research to improve the performance of TEs. However, mass production of high-performance TEs is expensive due to costly materials and fabrication techniques.
Solar cells which convert solar energy directly into electricity are among one of the most viable solutions to the worlds foreseeable energy crisis and global environmental issues. One key strategy to improve the efficiency of solar cells is to enhance the overlap between their absorption spectra and the solar spectrum. When two or more subcells with distinct and complementary absorption spectra are stacked, the tandem solar cells are created and a broader range of the solar spectrum can be absorbed and more solar energy can be harvested.
Patients who suffer from severe burns require immediate wound closure to ensure survival and facilitate healing. The current gold standard in surgical practice is the use of split-surface autographs, allographs, or skin substitutes, but limitation range from the lack of layered tissue organization, the potential for immunological rejection, and the need for high quantities of donated tissue.
Using surface characterization techniques, the relationship between the surface hydrophilicity level of the positive electrode and the electrochemical performance of a rechargeable aqueous battery system will be investigated. Oxygen is generated during the battery operation due to the decomposing of water, the solvent for the electrolyte, and may cover the surface of the positive electrode, thus hinder the battery operation.
