A novel bio-based superabsorbent polymer material based on a proteinaceous natural polymer is introduced herein. There is further disclosed a method for the manufacture of such a bio-based crosslinked superabsorbent polymer material. The method includes, but not limited to, introducing polymerizable unsaturated groups onto the natural polymer or its derivative so as to yield a macromonomer. The macromonomer can be formed by covalently binding unsaturated carbon-carbon double bonds to a proteinaceous substrate through a reaction of a selected chemical compound and the amino group on the proteinaceous substrate. The macromonomer is then copolymerized with unsaturated co-monomer(s) to form a crosslinked superabsorbent material.

Techniques to improve efficiencies of power amplifiers in wireless communication devices are described herein. In one embodiment, an envelope tracking supply modulator includes a pre-amplifier having an input coupled to an envelope signal and another input coupled to a threshold voltage signal, a de-multiplexer coupled to an output of the pre-amplifier, a pulse frequency modulator having an input coupled to an output of the de-multiplexer, and a pulse width modulator having an input coupled to the output of the de-multiplexer. The de-multiplexer is configured to allow the pulse frequency modulator to modulate a switching frequency to generate a switched signal according to a slew rate of the envelope signal or allow the pulse width modulator to provide the switched signal as a current source with a constant frequency, based on a comparison result between the envelope signal and the threshold voltage signal at the pre-amplifier.

The methods herein provide for analysis of ion populations. Certain aspects include: obtaining a first data set that includes: a first binary On-OFF frequency sweep across a range of frequencies resulting in a first raw data in the time domain and obtaining a second data set that includes: a second binary On-OFF frequency sweep 180 out of phase from the first binary On-OFF frequency sweep so as to result in a second raw data in the time domain from received ion current resulting from the second binary On-OFF frequency sweep. Thereafter the two data sets are combined to provide for raw mobility signals of the ion populations in the time domain for each m/z over a range of selected m/z values. Additional aspects include a hybrid system for performing the methods disclosed herein.

Current Opinion in Plant Biology | Year: 2012
Membrane proteins are essential to move amino acids in or out of plant cells as well as between organelles. While many putative amino acid transporters have been identified, function in nitrogen movement in plants has only been shown for a few proteins. Those studies demonstrate that import systems are fundamental in partitioning of amino acids at cellular and whole plant level. Physiological data further suggest that amino acid transporters are key-regulators in plant metabolism and that their activities affect growth and development. By contrast, knowledge on the molecular mechanisms of cellular export processes as well as on intracellular transport of amino acids is scarce. Similarly, little is known about the regulation of amino acid transporter function and involvement of the transporters in amino acid signaling. Future studies need to identify the missing components to elucidate the importance of amino acid transport processes for whole plant physiology and productivity. © 2012 Elsevier Ltd.

Few-body physics has played a prominent role in atomic, molecular and nuclear physics since the early days of quantum mechanics. It is now possible - thanks to tremendous progress in cooling, trapping and manipulating ultracold samples - to experimentally study few-body phenomena in trapped atomic and molecular systems with unprecedented control. This review summarizes recent studies of few-body phenomena in trapped atomic and molecular gases, with an emphasis on small trapped systems. We start by introducing the free-space scattering properties and then investigate what happens when two particles, bosons or fermions, are placed in an external confinement. Next, various three-body systems are treated analytically in limiting cases. Our current understanding of larger two-component Fermi systems and Bose systems is reviewed, and connections with the corresponding bulk systems are established. Lastly, future prospects and challenges are discussed. Throughout this review, commonalities with other systems such as nuclei or quantum dots are highlighted. © 2012 IOP Publishing Ltd.

Groundwater is an important drinking water source for many communities. Who depends on groundwater for drinking water ? Three of four American cities, 95% of the rural American population, and over half of all Americans. Wide scale contamination of groundwater threatens many of these sources. The state-of-the-science for cleaning up contaminated groundwater is mired in 1950s technology because the pollutants and the flowing groundwaters in which they occur are out of sight and very difficult to monitor. This makes it particularly difficult to design so-called in situ clean-up methods, that rely on injecting mixtures into the subsurface to make chemical reactions underground that convert the contaminants to non-toxic products.
The problem to be studied in this project is how groundwater clean-up happens underground. The project will use a recently discovered method of tracking the moving front between the contaminated (plume) and the non-contaminated groundwater as a basis for predicting the overall rate of chemical transformation in situ. This new method is a recent invention from the theory of turbulence, a field that has challenged human minds since the time of DaVinci, and it promises to provide a much more accurate way of accounting the overall rate of clean-up, even when it is difficult to know exactly the location of the contaminant plume. This project includes both controlled experiments in the laboratory and field site testing to complete the development of this method of designing groundwater clean-up. This innovative and powerful approach does not require the site manager to know exactly where the plume is, like other methods, but it only requires the total surface area of the plume.
The broader significance of this research includes: development of new methods to help federal and state agencies, cities, groundwater contamination responsible parties, and anyone responsible for groundwater quality, to design and manage in situ groundwater remediation strategies all over the United States. This project shares the work with learning people at all levels from Kindergarten to College, in order to achieve broad training goals. The project involves both undergraduate and graduate students in interdisciplinary education, includes classes with approximately 75 K-12 students as well as their teachers per year involved in different aspects of engineering and environmental processes in soils through one-day hands-on field trips to the UC Davis campus, and expansion of two UC Davis graduate courses to include material learned in this project.
