Quantifying vapor transfer into evaporating ethanol drops in humid atmosphere

03.07.2018 | Yutaku Kita; Yuya Okauchi; Yuki Fukatani; Daniel Orejon; Masamichi Kohno; Yasuyuki Takata; Khellil Sefiane, Physical Chemistry Chemical Physics, 2018

The effect of ambient temperature and relative humidity on the dynamics of ethanol drop evaporation is investigated. Although drop evaporation of mixtures and pure fluids has been extensively studied, very little is known about the transition from pure fluid to a binary mixture following transfer ...

Crystalline, room-temperature stable phosphine–SO2 adducts: generation of sulfur monoxide from sulfur dioxide

03.07.2018 | Florenz Buß; Philipp Rotering; Christian Mück-Lichtenfeld; Fabian Dielmann, Dalton Transactions, 2018

The particularly basic phosphines 1a–c readily form isolable, zwitterionic Lewis base adducts with SO2 that were fully characterized including by X-ray diffraction studies. Computational and reactivity studies show that these adducts readily release SO at room temperature driven by the formation ...

High-capacitance Ti3C2Tx MXene enabled by etching submicron Ti3AlC2 grains grown in molten salt

03.07.2018 | Cong Cui; Minmin Hu; Chao Zhang; Renfei Cheng; Jinxing Yang; Xiaohui Wang, Chemical Communication, 2018

Submicron Ti3AlC2 grains are grown in molten salt. Etching the grains gives rise to small-sized Ti3C2Tx MXene particulates with capacitance more than twice the large ones derived from conventional high-temperature synthesis. Detailed electrochemical, structural, and spectroscopic studies ...

A low temperature investigation of the gas-phase N(2D) + NO reaction. Towards a viable source of N(2D) atoms for kinetic studies in astrochemistry

03.07.2018 | Dianailys Nuñez-Reyes; Kevin M. Hickson, Physical Chemistry Chemical Physics, 2018

The gas-phase reaction of metastable atomic nitrogen N(2D) with nitric oxide has been investigated over the 296–50 K temperature range using a supersonic flow reactor. As N(2D) could not be produced photolytically in the present work, these excited state atoms were generated instead through the ...

Unexpected Refacetting of Palladium Nanoparticles under Atmospheric N2 Condition

03.07.2018 | Xun Zhang; Jun Meng; Beien Zhu; Wentao Yuan; Hangsheng Yang; Ze Zhang; Yi Gao; Yong Wang, Chemical Communication, 2018

We demonstrate an unexpected refacetting process of Pd nanoparticles induced by N2 under atmospheric pressure at elevated temperature by in situ TEM observation. The morphology change with a notable increase of Pd {110} facets fraction was visualized by the atomic-scale TEM images and further ...

Palladium catalyzed stereocontrolled synthesis of C-aryl glycosides using glycals and arenediazonium salts at room temperature

03.07.2018 | Jeyakumar Kandasamy; Adesh Kumar Singh, Organic & Biomolecular Chemistry, 2018

A stereocontrolled synthesis of aryl-C-glycosides was achieved using glycals and aryldiazonium salts in the presence of palladium acetate. A wide range of glycals including D-glucal, D-galactal, L-rhamanal, D-xylal and D-ribal underwent C-arylation at the anomeric carbon in the presence of ...

Room Temperature Carbon Monoxide Oxidation over Two-Dimensional Gold-Loaded Mesoporous Iron Oxide Nanoflakes

03.07.2018 | Yusuf Kaneti; Shunsuke Tanaka; Yohei Jikihara; Tsuruo Nakayama; Yoshio Bando; M Haruta; Mohammad Shahriar Hossain; D ..., Chemical Communication, 2018

In this work, we fabricate a highly effective catalyst for carbon monoxide oxidation based on gold-loaded mesoporous maghemite nanoflakes which exhibit nearly 100% CO conversion and a very high specific activity of 8.41 molCO gAu‒1 h‒1 at room temperature. Such excellent catalytic activity is ...
