Abstract:: ... Biochar is used as a soil amendment to improve soil quality and fertility. The performance of biochar changes as it ages in fields. Artificial biochar aging methods (i.e. chemical oxidation) are considered proxies for natural biochar aging and help to evaluate the long-term effects of biochar amendment in soil. However, few studies have focused on how close artificial biochar aging methods are to ...

Abstract:: ... Despite the rapid development of polymer light-emitting diodes (PLEDs), the overall device efficiency is still limited because ∼80% of the generated light is trapped in a conventional device architecture by the high refractive index of organic materials and the optical confinement and internal reflection. The implementation of the energy dissipation compensation techniques is urgently required for ...

Abstract:: ... A new type of capacitance-coupled contactless conductivity detection (C⁴D) system with sidewall electrodes was proposed for integration on a silicon-on-isolator-poly(dimethylsiloxane) (SOI-PDMS) hybrid low-voltage-driven electrophoresis microchip. By a microelectromechanical system process, the sidewall electrodes were fabricated precisely at either side of the separation channel. The area of the ...

Abstract:: ... In this paper, we briefly review international Good Agricultural Practice (GAP) regulations related to traditional Chinese medicine herbs (TCM herbs) and the background of the drafting process and the implementation of GAP for TCM herbs in China. We also have summarized progress and achievements since the implementation of GAP for TCM herbs in 2002. Up to 2010, a total of 99 GAP bases were formall ...

Subject:: carbon nanotubes; electrophoresis; nanopores; polymerase chain reaction; single-stranded DNA
Abstract:: ... We report the fabrication of devices in which one single-walled carbon nanotube spans a barrier between two fluid reservoirs, enabling direct electrical measurement of ion transport through the tube. A fraction of the tubes pass anomalously high ionic currents. Electrophoretic transport of small single-stranded DNA oligomers through these tubes is marked by large transient increases in ion current ...
