To obtain synthesis of MIP, (+) catechin (and caffeine) was employed as the template, AM (and MAA) as the monomer, EGDMA as the crosslinker, and AIBN as the initiator. A solution of (+) catechin (and caffeine) (0.2mg/mL in methanol) was utilized in the solid extraction cartridges following loading, washing, and elution procedures with acetonitrile, methanol, and methanol/acetic acid (90/10, %v/v) as the solvents, respectively. This multi-solid-phase extraction protocol was applied for the extraction of caffeine and some catechin compounds from green tea. A comparison was made between the results obtained with the caffeine and (+) catechin MIP cartridges, blank polymer, and a traditional C18 reversed-phase cartridge. It was thereupon found that the recovery of caffeine by the caffeine-MIP-based sorbent used in this work was almost two and four times greater than that by a commercially available C Number of references:27 Main heading:Phenols Controlled terms:Acetonitrile - Bioelectric phenomena - Chemical sensors - Extraction - Methanol - Organic solvents - Plasma waves - Polymers - Projectiles - Sorption Uncontrolled terms:caffeine - Catechin compounds - Green tea - HPLC - Molecular imprinted polymers - multi-solid-phase extraction Classification code:932.3 Plasma Physics - 815.1 Polymeric Materials - 804.1 Organic Compounds - 802.3 Chemical Operations - 801 Chemistry - 701.1 Electricity: Basic Concepts and Phenomena - 654 Rockets and Rocket Propulsion DOI:10.1080/10826076.2011.576296 Database:Compendex Compilation and indexing terms, Copyright 2011 Elsevier Inc.

Phonon transmission across multiple defects behaves as a cascade scattering based with the random phase approximation. We elucidate that phonon scattering by structural defects is related to the spatial fluctuations of local vibrational density of states (LVDOS). An effective method of tuning thermal transport in low-dimensional systems through the modulation of LVDOS has been proposed. Our findings provide insights into experimentally controlling thermal transport in nanoscale devices. © 2011 American Institute of Physics.

Box 1331, Piscataway, NJ 08855-1331, United States Abstract:The continuous effort to improve efficiency, reduce particle, and greenhouse gase emissions leads to the emergence of the concept more electric. This concept helps to boost the performance as well as the flexibility of the domestic and vehicular applications; however, on the other hand, it excessively burdens current power networks (including vehicle power systems). In order to remedy this problem, simultaneous usage of renewable sources and energy storages is encouraged. A multiconverter system is commonly adopted to process the renewable power in form of distributed generation. However, due to the discrete structure of such systems, power flow and load regulation are coordinated via communication channel, which inevitably reduces the reliability and dynamic response of the system. This paper presents the concept of multiport power electronic interface (MPEI) for renewable energy sources and storages. With a unified modular topology and highly integrated digital control system, controlled quasi-current source is achieved for each input port in both steady-state and transient power-sharing modes. MPEI analysis, modeling, design, and system operation are treated in a systematic manner in this paper. Both power stages and digital control system are implemented for a five-port MPEI. Experiments are conducted under meaningful operation scenarios. The results are presented to prove the feasibility of MPEI concept and system design methodology. © 2011 IEEE.

Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract:A novel strategy was proposed to fabricate carbon fiber microelectrodes (CFMEs). The resultant CFMEs were characterized using scan electron microscopy (SEM) and cyclic voltammetry (CV). Compared to the conventional method, the proposed method only needs a simple heating step for achieving CFMEs without additional pulled, sealed and back-filled procedure. The electrochemical behaviors of 2,4-Dichlorophenol (2,4-DCP) at fabricated CFMEs in pH (2.0-9.0) was for the first time studied and demonstrated a two-charge and two-proton transference process. © (2011) Trans Tech Publications.
