Fragility and glass transition temperature of polymer confined under isobaric and isochoric conditions
22.05.2013 | Chuan Zhang; Rodney D. Priestley, Soft Matter, 2013
It is now well established that the glass transition temperature (Tg) of polymers can deviate substantially from the bulk with nanoscale confinement. Understanding the impact of confinement on the Tg of polymers is important but it does not provide information about the temperature dependence ...
Silver-catalysed trifluoromethylation of arenes at room temperature
22.05.2013 | Michael Greaney; Sangwon Seo; John B Taylor, Chemical Communication, 2013
A variety of heteroarenes and electron rich arenes can be trifluoromethylated at room temperature with TMSCF3, catalytic silver and ArI(OAc)2.
Supersonic microwave co-assistance (SMC) efficient synthesis of red luminescent Eu3+ activated silver molybdates and their phase-dependent evolution processes
22.05.2013 | Qianming Wang, CrystEngComm, 2013
The chemical effects of high intensity ultrasound and microwave irradiation on the preparation of europium (III) activated silver molybdates were carried out and characteristic red emission was successfully achieved at very low temperature (70 oC) in 40 minutes. X-ray powder diffraction ...
Prediction of the concentration dependence of the surface tension and density of salt solutions: atomistic simulations with polarizable and nonpolarizable models.
22.05.2013 | Jean Claude Neyt; Aurelie Wender; Véronique Lachet; Aziz Ghoufi; Patrice Malfreyt, Physical Chemistry Chemical Physics, 2013
Molecular simulations using polarizable and nonpolarizable models for water and ions are carried out to predict the dependence of the surface tension on salt concentration. The polarizable water and ion models are based on the classical Drude oscillators. The temperature dependence of the ...
A NOVEL LTCC ELECTROCHEMICAL CELL CONSTRUCTION AND CHARACTERIZATION: A DETECTION COMPARTMENT TO PORTABLE DEVICES
22.05.2013 | Naira Canevarolo Pesquero; Mario Ricardo Gongora-Rubio; Hideko Yamanaka, Analyst, 2013
In this work we described for the first time the construction of a 25 µL electrochemical cell from low temperature co-fired ceramic (LTCC) material and carbon screen-printed electrode applicable in portable devices. Firstly, a carbon screen-printed electrode was prepared and characterized by ...
