Polychiral Multi-Walled Carbon Nanotube Solar Cells

As research on physical and electronic properties of graphene and carbon nanotubes (CNTs) continues, their possible applications expand. CNTs can possess different chiralities, one family of which forms semiconductors that exhibit the photovoltaic properties of silicon and gallium arsenide. These properties demonstrate the viability of CNTs as candidate for solar cells; however, unlike other semiconductors, the differing chiralities of semiconductor CNTs also have different absorption spectra, allowing each chirality to absorb a specific wavelength of light. Combining this property with the concentric layering of single walled carbon nanotubes(SWCNTs) to form multiwalled carbon nanotubes (MWCNTs) permits the creation of polychiral MWCNTs, in which each layer has a different chirality. Each nanotube in a solar cell created from these polychiral MWCNTs would have the combined absorption spectrum of its constituent SWCNTs. MWCNTs whose combined absorption spectra most closely resembles solar emissions will form solar cells whose efficiency surpasses silicon based cells.

The Regeneration of Limbs Using Induced Multipotent Stem Cells

Prosthetics have been in use for thousands of years, but have advanced exponentially in recent years. Modern technologies implemented in various prosthetics are able to send signals from the brain to the artificial limb, allowing it to be controlled like a natural limb. This new technology uses nerve signals to control a regrown limb of induced multipotent stem cells. The stem cells come from adult bone marrow and are inserted into biodegradable hyperelastic bone. This is the prosthetic “bone” base prompts tissue, muscle, nerve, and bone cells to regrow. After the regeneration occurs, the hyperelastic bone will dissolve within the body. The result is a natural, fully functioning limb that gives amputees more confidence in their own appearance and attitudes, and allows them to return to their normal lives as if they had never lost a limb.

MelaNOMORE is a noninvasive scanner and cooling lotion kit that uses inrared technology to detect small changes in skin temperature to diagnose melanoma. Using infrared technology, the scanner will then detect the subtle differences in temperature hoping to identify areas of the skin with possible cancerous cells as cancer cells heat up faster than healthy body cells.

D.A.I.S.Y. (Depression Assistance In Senior Years)

Many older adults suffer from depression due to the changes that accompany growing older. Taking care of a dog can negate feelings of isolation and loneliness, which are a trigger for geriatric depression. Studies show that older adults who own pets have lower blood pressure, higher levels of serotonin and dopamine, decreased risk of heart attacks and don’t need to see their doctors as often. Despite these benefits, many older adults worry that they will not be able to take care of a pet, and this deters them from adopting a dog. We propose a robotic pet, named D.A.I.S.Y, which stands for Depression Assistance In Senior Years, that will simulate the companionship of a live pet by responding to human emotions and independently interacting with its owner. Our robotic pet will benefit the mental and physical health of elderly people without the cost and care of a living pet.

Using Isolated Extracellular Matrices for Creating Vascular Scaffolds for Organ Replication and Transplantation

In the United States there is a growing problem. As lifestyle factors evolve to a contemporary society full of high fructose corn syrup, one-dollar cheeseburgers, soda with every meal, and sedentary lifestyles, an ever-growing number of people face chronic diseases. Diabetes, Cardiovascular disease, and Cirrhosis (live disease) are the most common conditions. The problem lies in the fact that each of these diseases involves, fully or partially, with organ failure. On average chronic conditions, along with old age and other factors, cause one person to be added to the organ list every 10 minutes. Of these people 20 die daily while waiting for a transplant (UNOS). This experiment is intended to provide an alternate method for producing viable organs for those in need by using Extracellular Matrices to enhance 3d printed organs or even become organs themselves.

Targeted Two-Drug Combo Therapy for Lupus

Systemic Lupus Erythematosus (SLE) is an autoimmune disease that affects millions of people worldwide. The fact that there is no cure for the disease is mostly due to the cause of lupus being unknown. However, in a recent study, attention was directed towards T cells, which play active roles in the onset of autoantibody production in lupus. The study involved the combination of two drugs for the normalization of T cell metabolism. We chose to design a future technology that would enhance the effects of this two-drug combo. Our targeted therapy involving monoclonal antibodies aids in the targeting and killing of malignant cells. The addition of monoclonal antibodies with the two-drug combo would target T cells and provide more effective access for the two-drug combo therapy to normalize T cell metabolism and potentially cure lupus.
