Rapid and Controllable Digital Microfluidic Heating by Surface Acoustic Waves

28.08.2015 | Richie J. Shilton, Virgilio Mattoli, Marco Travagliati, Matteo Agostini, Andrea Desii, Fabio Beltram, Marco Cecchini, Advanced Functional Materials, 2015

Fast and controllable surface acoustic wave (SAW) driven digital microfluidic temperature changes are demonstrated. Within typical operating conditions, the direct acoustic heating effect is shown to lead to a maximum temperature increase of about 10 °C in microliter water droplets. The ...


Coatings with thermally switchable surface energy produced from poly(ethylene oxide)‐poly(dimethylsiloxane) block copolymer films

28.08.2015 | Raleigh L. Davis, Richard A. Register, Journal of Polymer Science Part B: Polymer Physics, 2015

ABSTRACT This work explores coatings with thermally switchable wetting behavior, based on block copolymers that possess both hydrophilic and hydrophobic segments. The amphiphilic block copolymers were synthesized by coupling allyl‐ended poly(ethylene oxide) (PEO) and hydride‐ended ...


IJMS, Vol. 16, Pages 20449-20467: Mechanistic and Kinetic Studies on the Homogeneous Gas-Phase Formation of PCTA/DTs from 2,4-Dichlorothiophenol and 2,4,6-Trichlorothiophenol

28.08.2015 | Xu, Fei ; Shi, Xiangli ; Li, Yunfeng ; Zhang, Qingzhu, International Journal of Molecular Sciences, 2015

Polychlorinated thianthrene/dibenzothiophenes (PCTA/DTs) are sulfur analogues compounds to polychlorinated dibenzo-p-dioxin/dibenzofurans (PCDD/Fs). Chlorothiophenols (CTPs) are key precursors to form PCTA/DTs. 2,4-DCTP has the minimum number of Cl atoms to form 2,4,6,8-tetrachlorinated ...


Effects of Free‐Air Carbon Dioxide Enrichment on Sap Flow and Canopy Microclimate of Maize Grown under Different Water Supply

26.08.2015 | R. Manderscheid, M. Erbs, S. Burkart, K.‐P. Wittich, F.‐J. Löpmeier, H.‐J. Weigel, Journal of Agronomy and Crop Science, 2015

Abstract The rise of atmospheric CO2 concentration ([CO2]) affects stomatal conductance and thus transpiration and leaf temperature. We evaluated the effect of elevated [CO2] levels under different water supply on daily sap flow and canopy microclimate (air temperature (Tc) and vapour pressure ...


Hydrophobicity: Effect of density & order on water’s rotational slowing down

26.08.2015 | John Tatini Titantah; Mikko Karttunen, Soft Matter, 2015

Ab initio Molecular Dynamics (AIMD) simulations of over 4.5 ns were performed in the temperature range of T=260 K-350 K with van der Waals corrections to investigate the relationship between local water density and tetrahedral order in bulk water and in the presence of a hydrophobe, ...


DFT Study of Proton Transfer in Methyl Urocanate and Butyl Urocanate

25.08.2015 | Janchai Yana, Suwabun Chirachanchai, Chatchai Jarumaneeroj, Vannajan Sanghiran Lee, Kanchanok Kodchakorn, Kohji Tash ..., Macromolecular Symposia, 2015

Summary Development of proton conductivity is necessary to improve polymer electrolyte efficiency of proton exchange membrane fuel cell (PEMFC) which is alternative environmentally friendly resource. Modification of polymer electrolyte has been employed using water free polymer instead of ...


Sustainability, Vol. 7, Pages 11401-11417: Temperature Vegetation Dryness Index Estimation of Soil Moisture under Different Tree Species

25.08.2015 | Chen, Shulin ; Wen, Zuomin ; Jiang, Hong ; Zhao, Qingjian ; Zhang, Xiuying ; Chen, Yan, Sustainability, 2015

The Laoshan forest is the largest forest in Nanjing, and it plays an important role in water resource management in Nanjing. The objectives of this study are to determine if the temperature vegetation dryness index (TVDI) is suitable to estimate the soil moisture and if soil moisture is ...


All characteristic Raman markers of tyrosine and tyrosinate originate from phenol ring fundamental vibrations

24.08.2015 | Belén Hernández, Yves‐Marie Coïc, Fernando Pflüger, Sergei G. Kruglik, Mahmoud Ghomi, Journal of Raman Spectroscopy, 2015

Raman data collected from free amino acid and peptide chains permit assignment of the seven markers located at approximately 1616, 1606, 1210, 1178, 850, 830, and 643 cm−1 to tyrosine. The effects induced by labile hydrogen deuteration, temperature, concentration, and protonation–deprotonation ...
