Multielectron redox chemistry of lanthanide Schiff-base complexes

Multielectron redox chemistry, which is essential in metal catalysed chemical transformations, is not easily accessible in lanthanide complexes. Here we explored the reductive chemistry of lanthanide complexes with tetradentate Schiff bases acting as redox ...

The influence of sodium and potassium hydroxide on volume changes in cementitious materials

Karen Scrivener, Aditya Kumar

This research investigates the influence of alkali hydroxides on unrestrained volume changes. A detailed multi-method approach is used to characterize the progress of cement hydration, autogenous and drying volume changes (i.e., shrinkage), autogenous RH d ...

Stereoselectivity and electrostatics in charge-transfer Mn- and Cs-TCNQ(4) networks on Ag(100)

Klaus Kern, Andrea Floris, Sebastian Stepanow, Tzu-Chun Tseng, Nasiba Abdurakhmanova

Controlling supramolecular self-assembly is a fundamental step towards molecular nanofabrication, which involves a formidable reverse engineering problem. It is known that a variety of structures are efficiently obtained by assembling appropriate organic m ...

Plasmon evolution and charge-density wave suppression in potassium intercalated 2H-TaSe2

Helmuth Berger

We have investigated the influence of potassium intercalation on the formation of the charge-density wave (CDW) instability in 2H-TaSe2 by means of electron energy-loss spectroscopy and density functional theory. Our observations are consistent with a fill ...

Dispensing and Hermetic Sealing Rb in a Miniature Reference Cell for Integrated Atomic Clocks

Herbert Shea, Peter Ryser, Thomas Maeder, Fabrizio Vecchio, Vinu Lalgudi Venkatraman

An innovative method for filling and sealing the reference cell for a Rubidium (Rb) integrated atomic clock is presented. We used a simple, low-temperature solder sealing technique for producing mini-cells of the size of 12 x 10 x 2 mm, suitable for Rb min ...

Doping of Alkali, Alkaline-Earth, and Transition Metals in Covalent-Organic Frameworks for Enhancing CO2 Capture by First-Principles Calculations and Molecular Simulations

Berend Smit

We use the multiscale simulation approach, which combines the first-principles calculations and grand canonical Monte Carlo simulations, to comprehensively study the doping of a series of alkali (Li, Na, and K), alkaline-earth (Be, Mg, and Ca), and transit ...

Development of low-firing lead-free thick-film materials on steel alloys for piezoresistive sensor applications

Peter Ryser, Thomas Maeder, Caroline Jacq

Piezoresistive sensors based on steel and other metallic substrates provide higher strain response than on standard ceramic substrates and are more easily packaged. But exposing high-strength steels to the standard high- temperature 850°C thick-film firing ...
