Coastal-based high-frequency (HF) radar systems are an increasingly used tool for measuring surface currents in the coastal ocean. These systems provide a spatial and temporal resolution not achievable with other methods. Standard-range sites typically generate hourly maps of surface currents on a 2km grid extending approximately 50km from shore while...
Metallic glasses (also referred to as amorphous metals) have been gaining interest in the materials science community in recent years. These amorphous materials demonstrate promising properties compared to their crystalline counterparts that include much higher strength and elastic strain limit, better corrosion and wear resistance, superior soft magnetism, and an...
Metabolic improvements and changes in gene expression were measured in mice fed polyphenol-rich extracts derived from apples and sweet cherries, and the common phytochemicals, quercetin and ellagic acid. Polyphenol-rich extracts were produced by solid phase extraction and column chromatography. Extracts and purified compounds were mixed into a high-fat (HF, 60%...
Radiogenic isotopes of hafnium (Hf) and neodymium (Nd) are powerful tracers for water mass transport and trace metal cycling in the present and past oceans. However, due to the scarcity of available data the processes governing their distribution are not well understood. Here we present the first combined dissolved Hf...
An estimated total of 30.3 million people have diabetes in the United States, a disease characterized by chronic elevation in blood glucose which over time, can lead to a host of health problems. Currently the most common types of diabetes are type 1, type 2, and gestational. The principal hormone...
Aqueous hydroxo Hf nanoclusters enable studies to identify and codify steps in the deposition of Hf-based oxide thin films from solution precursors. HfOCl2 reacts with combinations of H2O2(aq), acids, and TMAH to produce polymetal species at high pH and low pH. X-ray scattering and spectroscopic methods reveal the nature of...
BACKGROUND: Consumption of raspberry products have been observed to produce healthful effects and reduce weight gain and positively shift metabolism in mice fed obesigenic diets. In the past, our lab has successfully shown a reduction in weight gain for mice consuming RPC+HF vs. mice fed HF alone. Currently, there is...
Metallic glasses (MGs), also called amorphous metals, are metals or metallic alloys trapped in a disordered glassy state. Their amorphous nature and absence of features such as crystal lattices and defects (dislocations, grain boundaries etc.) endows them with a host of properties that far surpass those of common crystalline materials....
Health benefits obtained from consumption of fruits and vegetables have the potential to improve the lifestyle of individuals. The walnut is a polyunsaturated fatty acid (PUFA)-rich whole food that is readily available in the U.S and has been shown to potentially reduce risk of Metabolic Syndrome. Furthermore, consumption of polyphenol...
A series of TiNbHf alloys ranging from 0-40 atomic %
Nb and 0-15 atomic % Hf were evaluated to investigate
low-elastic modulus phenomena which occur in this ternary
system. The desirability of utilizing corrosion-resistant, biocompatible alloys with elastic modulus values
approaching that of human bone for medical prosthetic
implants provides...
