Elastic polyurethane foams containing graphene nanoplatelets

21-Mar-2017 | Łukasz Piszczyk, Paulina Kosmela, Michał Strankowski, Advances in Polymer Technology, 2017

Abstract Elastic polyurethane foams were produced from two‐component polyurethane systems (SPECFLEX NE 113 izocyjanian/NR 816 poliol system—SPC and Elastic MBMarket company system POLYOL ET MB 500/ISO ET MB 800—ET) by using a one‐step method. The foams were a graphene nanoplatelets (GNP) in ...

Effects of Preferential Solvation Revealed by Time-Resolved Magnetic Field Effects

17-Mar-2017 | Van Thi Bich Pham; Hao Minh Hoang; Günter Grampp; Daniel R. Kattnig, The Journal of Physical Chemistry B, 2017

External magnetic fields can impact recombination yields of photoinduced electron transfer reactions by affecting the spin dynamics in transient, spin-correlated radical pair intermediates. For exciplex-forming donor–acceptor systems, this magnetic field effect (MFE) can be investigated ...

Investigation of the reaction of ozone with isoprene, methacrolein and methyl vinyl ketone using the HELIOS Chamber

09-Mar-2017 | Yangang Ren; Benoit Grosselin; Véronique Daële; Abdelwahid Mellouki, Faraday Discussions, 2017

The rate constants for the ozonolysis of isoprene (ISO), methacrolein (MACR) and methyl vinyl ketone (MVK) have been measured using the newly built large volume atmospheric simulation chamber at CNRS-Orleans (France), HELIOS (cHambrE de simuLation atmosphérique à Irradiation naturelle d’OrléanS). ...

Synthesis, structural characterization and magnetic behaviour of a family of [CoIII2LnIII2] butterfly compounds

09-Mar-2017 | Alejandro V. Funes; Luca Carrella; Yvonne Rechkemmer; Joris van Slageren; Eva Rentschler; Pablo Alborés, Dalton Transactions, 2017

We have successfully prepared and structurally characterized a family of butterfly-like [CoIII2LnIII2] complexes where all magnetic properties are due to the Ln(iii) ions. The complexes with Ln = Tb(1), Dy(2), Ho(3), Er(4) and Yb(5) are iso-structural. An exception is the complex with Ln = Gd(6) ...

A Pyridine Alkoxide Chelate Ligand That Promotes Both Unusually High Oxidation States and Water-Oxidation Catalysis

08-Mar-2017 | Thoe K. Michaelos; Dimitar Y. Shopov; Shashi Bhushan Sinha; Liam S. Sharninghausen; Katherine J. Fisher; Hannah M. C ..., Accounts of Chemical Research, 2017

ConspectusWater-oxidation catalysis is a critical bottleneck in the direct generation of solar fuels by artificial photosynthesis. Catalytic oxidation of difficult substrates such as water requires harsh conditions, so the ligand must be designed both to stabilize high oxidation states of the ...

Yb14MgBi11: Structure, Thermoelectric Properties and the Effect of Structure on Low Lattice Thermal Conductivity

05-Mar-2017 | Yufei Hu; Susan M Kauzlarich, Dalton Transactions, 2017

Zintl phases Yb14MnSb11 and Yb14MgSb11, which share the same complex structure type, have been demonstrated as the best p-type thermoelectric materials for the high temperature region (800-1200K). A new iso-structural compound, Yb14MgBi11, was synthesized in order to investigate the structure and ...

Computationally Guided Discovery of Metal-Decorated Metal–Organic Frameworks Active for Catalysis

04-Mar-2017 | Dong Yang; Mohammad R. Momeni; Hakan Demir; Dale R. Pahls; Martino Rimoldi; Timothy C Wang; Omar Farha; J T Hupp; ..., Faraday Discussions, 2017

The metal-organic framework NU-1000, with Zr6-oxo, hydroxo, and aqua nodes, was modified by incorporation of hydroxylated Al(III) ions by ALD-like chemistry with [Al(CH3)2(iso-propoxide)]2 followed by steam (ALD = atomic layer deposition). Al ions were installed to the extent of approximately 7 ...
