Materials, Vol. 8, Pages 5452-5466: X-Ray Spectroscopy of Ultra-Thin Oxide/Oxide Heteroepitaxial Films: A Case Study of Single-Nanometer VO2/TiO2

21.08.2015 | Quackenbush, Nicholas F.; Paik, Hanjong ; Woicik, Joseph C.; Arena, Dario A.; Schlom, Darrell G.; Piper, Louis F. J., Materials, 2015

Epitaxial ultra-thin oxide films can support large percent level strains well beyond their bulk counterparts, thereby enabling strain-engineering in oxides that can tailor various phenomena. At these reduced dimensions (typically < 10 nm), contributions from the substrate can dwarf the signal ...

Molecules, Vol. 20, Pages 15273-15286: Ultrasound-Assisted Aqueous Two-Phase System for Extraction and Enrichment of Zanthoxylum armatum Lignans

20.08.2015 | Guo, Tao ; Su, Dan ; Huang, Yan ; Wang, Ya ; Li, Yong-Hui, Molecules, 2015

In the study, an aqueous two phase system (ATPS) coupled with ultrasound was employed to extract lignans from Zanthoxylum armatum. Three standard lignans, namely (−)-fargesin, sesamin and L-asarinin, were used as marker compounds, and extraction was optimized and projected by response surface ...

IJMS, Vol. 16, Pages 19752-19768: Polymer/Iron Oxide Nanoparticle Composites—A Straight Forward and Scalable Synthesis Approach

20.08.2015 | Sommertune, Jens ; Sugunan, Abhilash ; Ahniyaz, Anwar ; Bejhed, Rebecca Stjernberg; Sarwe, Anna ; Johansson, Christe ..., International Journal of Molecular Sciences, 2015

Magnetic nanoparticle systems can be divided into single-core nanoparticles (with only one magnetic core per particle) and magnetic multi-core nanoparticles (with several magnetic cores per particle). Here, we report multi-core nanoparticle synthesis based on a controlled precipitation process ...

Energies, Vol. 8, Pages 8814-8834: Novel Method for Measuring the Heat Collection Rate and Heat Loss Coefficient of Water-in-Glass Evacuated Tube Solar Water Heaters Based on Artificial Neural Networks and Support Vector Machine

20.08.2015 | Liu, Zhijian ; Li, Hao ; Zhang, Xinyu ; Jin, Guangya ; Cheng, Kewei, Energies, 2015

The determinations of heat collection rate and heat loss coefficient are crucial for the evaluation of in service water-in-glass evacuated tube solar water heaters. However, the direct determination requires complex detection devices and a series of standard experiments, which also wastes too ...

Sensors, Vol. 15, Pages 20659-20677: Ultrahigh-Temperature Regeneration of Long Period Gratings (LPGs) in Boron-Codoped Germanosilicate Optical Fibre

20.08.2015 | Liu, Wen ; Cook, Kevin ; Canning, John, Sensors, 2015

The regeneration of UV-written long period gratings (LPG) in boron-codoped germanosilicate “W” fibre is demonstrated and studied. They survive temperatures over 1000 °C. Compared with regenerated FBGs fabricated in the same type of fibre, the evolution curves of LPGs during regeneration and ...

Molecules, Vol. 20, Pages 15175-15191: Characterization of the Sublimation and Vapor Pressure of 2-(2-Nitrovinyl) Furan (G-0) Using Thermogravimetric Analysis: Effects of Complexation with Cyclodextrins

19.08.2015 | Ruz, Vivian ; González, Mirtha Mayra; Winant, Danny ; Rodríguez, Zenaida ; Van den Mooter, Guy, Molecules, 2015

In the present work, the sublimation of crystalline solid 2-(2-nitrovinyl) furan (G-0) in the temperature range of 35 to 60 °C (below the melting point of the drug) was studied using thermogravimetric analysis (TGA). The sublimated product was characterized using Fourier-transformed-infrared ...

Energies, Vol. 8, Pages 8775-8797: Analysis of Unit Process Cost for an Engineering-Scale Pyroprocess Facility Using a Process Costing Method in Korea

18.08.2015 | Kim, Sungki ; Ko, Wonil ; Bang, Sungsig, Energies, 2015

Pyroprocessing, which is a dry recycling method, converts spent nuclear fuel into U (Uranium)/TRU (TRansUranium) metal ingots in a high-temperature molten salt phase. This paper provides the unit process cost of a pyroprocess facility that can process up to 10 tons of pyroprocessing product per ...

Materials, Vol. 8, Pages 5313-5320: Capacitive Behavior of Single Gallium Oxide Nanobelt

17.08.2015 | Cai, Haitao ; Liu, Hang ; Zhu, Huichao ; Shao, Pai ; Hou, Changmin, Materials, 2015

In this research, monocrystalline gallium oxide (Ga2O3) nanobelts were synthesized through oxidation of metal gallium at high temperature. An electronic device, based on an individual Ga2O3 nanobelt on Pt interdigital electrodes (IDEs), was fabricated to investigate the electrical characteristics ...
