The objectives of this study were to 1) measure and compare the compositional differences of essential oil among three hop cultivars ('Centennial’, 'Citra' and 'Nelson Sauvin'), 2) identify the odor-active aroma compounds in three varieties of hops and 3) investigate the behavior of hop-derived aroma compounds in beers prepared by...
Significant challenges remain before lithium-ion batteries can support the decarbonization of the transportation and power sectors required to avert catastrophic climate change. The energy density of these batteries must be increased, while decreasing the price, and maintaining or increasing their lifespan. To improve the practical energy density of existing materials,...
Oxides are a versatile class of materials with a wide range of electronic, optical, and magnetic properties. This makes them ideal for use in a multitude of functional devices for oxide electronics, electrochemical conversion, and storage. The overall performance of these devices is governed by atomic scale charge and mass...
Water scarcity and extreme weather present substantial risks for agricultural production on the U.S. West Coast. Farmers adapt to water supply uncertainties and climate risks by changing water application rates, adjusting irrigated acres, adopting more efficient irrigation technology, and altering crop mix. Many policy options are available to attain sustainable...
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death in the United States. Patients with cirrhosis are more likely to develop HCC. More than 80% of HCC patients are found have preexisting cirrhosis. The prevalence of cirrhosis increased from 0.26% to 0.3.% between 1999 to 2010 and...
Cell division, arguably the most important event during the life cycle of the eukaryotic cell, is achieved through a complicated yet beautiful machinery. The mitotic spindle — a microtubule-based bipolar structure—is the cellular machinery responsible for the correct segregation of the genetic material, chromosomes. The protein-based nanomachines termed molecular motors...
High vegetative growth of Pinot Noir vine is a common problem in most vineyards of Oregon's Willamette Valley, where sunlight exposure and heat accumulation are limited. Consequently, growers in this region commonly use vineyard management strategies to regulate vine vigor and improve grape and wine quality. Wine quality is greatly...
Metallic glasses are attracting tremendous attention because of their fundamental significance and great potential to be used as structural or functional materials in engineering applications. Significant efforts have been devoted to studying their unique properties as well as their disordered nature. Metallic glasses possess much higher strength and elastic strain...
Heterogeneous catalysis modulates the rate and selectivity of reaction processes by
stabilizing a series of intermediate states on solid surfaces, facilitating the production
of many commodity chemicals modern society relies upon. Conventional, thermal
catalytic processes—conducted at elevated temperatures and pressures—source
thermal, mechanical, and chemical potential energy from carbon-hydrogen bonds—
combustion...
It is desirable for complex engineered systems to perform missions efficiently and economically, even when these missions' complex, variable, long-term operational profiles make it likely for hazards to arise. It is thus important to design these systems to be resilient so that they will actively prevent and recover from hazards...
Although geodetic measurements of interseismic deformation in interior Tibet suggest slow
strain accumulation, active slip along the right-lateral Gyaring Co Fault is suggested to be between 8
and 21 mm/yr. Reliable geologic constraints on the slip rate along this fault are sparse. Here we document
12 ± 2 m of...

Quality safety traceability system has adopted by most fishery enterprises as an important part of the strategic management. As the consequence, the end product is supposed to be higher. That consumers whether to accept has a direct impact on system successful implementation. This paper proposes a framework to research consumer...
There is an emerging interest in developing wearable electronics as a platform, which
provides the flexibility of a wearable while maintaining its promising functionality as smart textiles. Metal-halide semiconductors are attractive materials with tunable optical and electrical properties. Researchers have widely studied and applied it for advanced
photonics and optoelectronic...
Resistance against Bean common mosaic virus (BCMV) in Phaseolus vulgaris is governed by six recessive resistance alleles at four loci. One of these alleles, bc-3, is able to protect P. vulgaris against all BCMV strains and against other potyviruses; bc-3 was identified as the eIF4E allele carrying mutated eukaryotic translation...
Grid-scale energy storage systems are urgently needed to increase the flexibility and rigidity of the grid for modern society and take full advantage of the renewable green energy resources such as solar energy and wind energy. Na-ion batteries (NIBs) and K-ion batteries (KIBs) have been emerged as one of the...
The development of nanomaterials and the potential enhancement of their chemical, mechanical, electrical, and optical properties have led to the investigation of methods for their synthesis at lower cost with enhanced performance for next generation devices. Along with the pursuit of new materials that exhibit properties of interest, industry requires...
The continued long-term use of fossil fuels as a primary energy source has resulted in dramatic increases in greenhouse gas emissions and the associated concerns of climate change and environmental pollution. A key strategy to circumvent these issues is a global shift away from fossil fuels toward renewable energy sources....
The grand plan of carbon neutralization and COP26 in Glasgow require a quick shift of energy sources from conventional fossil fuel to a more renewable substitute such as wind, or solar energy. However, the intermittency of those renewable energy sources does not meet the demand of the energy, which requires...
Water electrolysis plays a pivotal role in achieving a green hydrogen economy by sourcing electricity from intermittent renewable sources. However, the efficiency of the electrolysis process is limited by the sluggish oxygen evolution reaction (OER) kinetics, whereas the kinetics of the hydrogen evolution reaction (HER) are more facile. This thesis...
Widespread installation of renewable energy sources, such as wind and solar, has been delayed by the lack of suitable stationary energy storage solutions. Current large-scale technologies, such as pumped hydro and compressed air, are geographically restricted. This is where electrochemical energy storage - batteries or hybrid capacitors can play a...
