Grad student Deniz Yucesoy receives Amazon Catalyst grant

prototype whitening losenge tablet Deniz Yucesoy, a graduate student in MSE's GEMSEC Labs, has been awarded an Amazon Catalyst grant for a project titled "Remineralizing Tooth Whitening Lozenges for Healthy Daily Use."

Current whitening products typically contain hydrogen peroxide as the active ingredient, which remove discoloration by dissolving stained minerals from the surface of teeth. Although this chemical-etching process reveals a fresh surface, it is often at the expense of removing healthy enamel — the fully mineralized crown of teeth which provides protection and cannot regenerate. As a consequence, the inner layer, dentin, becomes exposed — creating complications, such as hypersensitivity and increased susceptibility to caries (cavities), which, taken together, far outweigh the cosmetic benefits.

Newly developed tooth-whitening lozenges dissolve in saliva recruiting calcium and phosphate ions to the surface of teeth and create a new mineral layer through a restorative process thereby eliminating undesirable stains. When fully developed through the Catalyst Project, whitening lozenges will be used, clinically and over-the-counter product worldwide, for both therapeutic (remineralization) and cosmetic (whitening) purposes providing a safer alternative to the existing peroxide-containing corrosive treatments.

The Whitening Lozenge Team members: Sanaz Saadat, Sami Dogan, MSE Professor Mehmet Sarikaya, MSE grad student Deniz Yucesoy, and MSE Research Scientist, Hanson Fong

Xu, team, step closer to nano-lasers

MSE associate professor Xiaodong Xu, along with Arka Majumdar, Assistant Professor of Electrical Engineering and Physics, and their team have discovered an important first step towards building electrically pumped nanolasers (or light-based sources). These lasers are critical in the development of integrated photonic based short-distance optical interconnects and sensors. Short distance optical interconnects can improve the performance of data centers, allowing them to be energy-efficient and support high performance parallel computing. The results were published in a recent edition of Nano Letters.

UW researcher pursues synthetic ‘scaffolds’ for muscle regeneration

Miqin Zhang, a professor in UW MSE, is looking for ways to help the body heal itself when injury, disease or surgery cause large-scale damage to one type of tissue in particular: skeletal muscle. Muscles have a limited ability to regenerate, repair and realign themselves properly after certain types of damage.

Zhang and her team are taking a synthetic approach to muscle regeneration. Their goal is to create a synthetic, porous, biologically compatible "scaffold" that mimics the normal extracellular environment of skeletal muscle &mdash' onto which human cells could migrate and grow new replacement fibers. Their research is published in the Nov. 16 issue of Advanced Materials.

In one-two punch, researchers load ‘nanocarriers’ to deliver cancer-fighting drugs and imaging molecules to tumors
MSE professor Miqin Zhang leads research on a new system to encase chemotherapy drugs within tiny, synthetic “nanocarrier” packages, which could be injected into patients and disassembled at the tumor site to release their toxic cargo. “Our nanocarrier system is really a hybrid addressing two needs — drug delivery and tumor imaging,” said Zhang, senior author on a paper published Sept. 27 in the journal Small. “First, this nanocarrier can deliver chemotherapy drugs and release them in the tumor area, which spares healthy tissue from toxic side effects. Second, we load the nanocarrier with materials to help doctors visualize the tumor, either using a microscope or by MRI scan.”

New protein bridges chemical divide for ‘seamless’ bioelectronics devices

MSE professor Mehmet Sarikaya leads research that has unveiled peptides that could improve results in how we treat disease, repair damaged tissue. and replace lost limbs. While implanted electrodes scar, wires overheat and our bodies struggle against ill-fitting pumps, pipes or valves, a paper published published Sept. 22 in Scientific Reports shows how a genetically engineered peptide can assemble into nanowires atop 2-D, solid surfaces that are just a single layer of atoms thick. These nanowire assemblages are critical because the peptides relay information across the bio/nano interface through molecular recognition — the same principles that underlie biochemical interactions such as an antibody binding to its specific antigen or protein binding to DNA.

UW scientists create ultrathin semiconductor heterostructures for new technological applications
A team led by Boeing Distinguished Associate Professor Xiaodong Xu successfully combined two different ultrathin semiconductors — each just one layer of atoms thick and roughly 100,000 times thinner than a human hair — to make a new two-dimensional heterostructure with potential uses in clean energy and optically-active electronics. The team announced its findings in a paper published Feb. 12 in the journal Science. "What we’re seeing here is distinct from heterostructures made of 3-D semiconductors," said Xu, who has a joint appointment in the Department of Physics. "We've created a system to study the special properties of these atomically thin layers and their potential to answer basic questions about physics and develop new electronic and photonic technologies."

Pauzauskie Team refrigerates liquids with a laser for the first time
UW engineers used an infrared laser to cool water by about 36 degrees Fahrenheit — a major breakthrough in the field. The UW team demonstrated a hydrothermal process to manufacture a well-known laser crystal for laser refrigeration applications in a faster, inexpensive, and scalable way. They also designed an instrument that uses a laser trap to "hold" a single nanocrystal and illuminate it. The instrument projects the particle’s "shadow" to allow observation of minute changes in its motion due to cooling. The team includes MSE assistant professor Paden Roder, PhD, MSE '15, and UW doctoral students Bennett E. Smith (chemistry), Xuezhe Zhou (MSE), and Matthew Crane (chemical engineering). Their study is to be published in the Proceedings of the National Academy of Sciences the week of Nov. 16.

Crystals form through a variety of paths, with implications for biological, materials and environmental research
New research shows a variety of pathways to crystal formation. Crystallization occurs across scientific disciplines; a shift in the picture of how it occurs has far-reaching consequences, says lead author and MSE affiliate professor James De Yoreo. These conclusions, published July 31 in Science with De Yoreo as lead author, have implications for decades-old questions in crystal formation, such as how animals and plants form minerals into shapes that have no relation to their original crystal symmetry or why some contaminants are so difficult to remove from stream sediments and groundwater. De Yoreo is also an affiliate professor in chemistry and a materials scientist and physicist at the Department of Energy’s Pacific Northwest National Laboratory.
