Single crystals of elemental or simple binary or ternary materials, such as Si, GaN or Nb3Sn, have been the basis of many past and current electronic, optoelectronic and energy technologies. However, there has been a recognition that in order to meet demanding future performance requirements and to enable realization of multiple functionalities in new application environments we need to explore...

Multidimensional solid-state NMR spectroscopy is used to refine the identification and abundance determination of functional groups in insoluble organic matter (IOM) isolated from a carbonaceous chondrite (Murchison, CM2). It is shown that IOM is composed primarily of highly substituted single ring aromatics, substituted furan/pyran moieties, highly branched oxygenated aliphatics, and carbonyl ...

Cloning of the Rabbit Organic Cation Transporter, rbOCT2, and Functional Comparisons with rbOCT1. Am J. Physiol. Renal Physiol. Multiple organic cation (OC) transporters are present in rabbit kidney and may play different functional roles. We cloned rbOCT2 and compared its function with that of rbOCT1. In transiently transfected COS-7 cells, rbOCT1 and rbOCT2 mediated uptake of [ 3 H]tetraethyl...

This communication demonstrates a method of transferring unreacted low molecular weight (LMW) siloxane oligomers from freshly prepared "dry" PDMS stamps for patterning organic semiconductors and conducting polymers into functional devices via selective wetting. The semiconductors were patterned onto the modified surfaces via dip-coating with well-resolved feature sizes as small as 1 mum. Functi...

BACKGROUND Conversion disorder (CD) is a psychiatric disorder, yet the diagnosis cannot be established without the expertise of a neurologist, as distinguishing a functional from an organic symptom relies on careful bedside examination. Joseph Babinski considered the absence of pronator drift as a 'positive sign' for hysterical paresis but the validity of this sign has never been evaluated. The...

Submicron atmospheric aerosol particles were collected during the Megacity Initiative: Local and Global Research Observation (MILAGRO) in March 2006 at three platforms located in the Mexico City urban area (at the Mexico City Atmospheric Monitoring System building – SIMAT), at about 60 km south-east of the metropolitan area (Altzomoni in the Cortes Pass), and on board the NCAR C130 aircraft. Or...

The organic cation/carnitine transporter OCTN2 transports carnitine in a sodium-dependent manner, whereas it transports organic cations sodium-independently. To elucidate the functional domain in OCTN2, we constructed chimeric proteins of human OCTN2 (hOCTN2) and mouse OCTN3 (mOCTN3) and introduced mutations at several amino acids conserved among human, rat and mouse OCTN2. We found that transm...

Biochar, as an high efficiency, environmental friendly, and low-cost adsorbent, is usually used as soil conditioner, bio-fuel, and carbon sequestration regent. Recently, biochar has attracted much attention in wastewater treatment field. There are plenty of studies about application of biochar to adsorb pollutants in wastewater, because of its low-cost preparation, high surface area, large pore...

Phytoremediation uses living higher plants for the removal and biochemical decomposition of environmental pollutants. In this paper Phase I metabolic pathways in the biotransformation reactions of organic pollutants in plants are reviewed. These reactions result in the introduction of functional groups in the xenobiotic molecule or the exposure of preexisting functional groups and lead to the f...
