Seasonal trends and temperature dependence of the snowfall/precipitation-day ratio in Switzerland

This paper analyzes the proportion of snowfall days relative to precipitation days, in order to assess the impact of changing temperatures on snowfall, while minimizing the impact of variations in precipitation frequency and intensity. We analyzed the rati ...

Capturing a DNA duplex under near-physiological conditions

Francesco Stellacci, Wei Xu

We report in situ trapping of a thiolated DNA duplex with eight base pairs into a polymer-protected gold nanogap device under near-physiological conditions. The double-stranded DNA was captured by electrophoresis and covalently attached to the nanogap elec ...

A novel time strip flow visualisation technique for investigation of intermittent dewetting and dryout in elongated bubble flow in a microchannel evaporator

John Richard Thome, Navid Borhani, Bruno Agostini

A flow visualisation study of flow boiling of R245fa in silicon multi-microchannels at low mass flux and moderate heat flux has been carried out with a high speed digital camera. The micro-evaporator had 67 channels of length 20 mm, width 223 mu m, and hei ...

Study and simulation of different scanning strategies in SLM

Rémy Glardon, Jamasp Jhabvala, Eric Boillat, Thibaud Antignac

In the SLM process, one has to balance between power and scan speed. When small scan speed is used, thermal gradients are important and local solidification can lead to cracks. On the other hand, when high speed is used, the power has to be huge and phenom ...

Improvement of elevated temperature mechanical properties of Cu–Ni–Sn–Pb alloys

Andreas Mortensen, Vincent Laporte, Doris Empl

Cu-Ni-Sn alloys with Pb additions exhibit high mechanical strength at room temperature coupled with good machinability but experience a significant ductility loss above the melting point of lead. We explore here the influence of minor additions of Al, Mn, ...

Metallocene Catalyzed Polyolefins For Improving Thermal And Mechanical Properties Of Bitumen Blends

John Christopher Plummer, Chiara Spadaro

Bitumen is a complex viscoelastic material used as a binder in applications ranging from road paving to waterproof membranes for roofing [1]. In such applications, bitumen is often blended with a polymer in order to improve its elasticity. The resulting po ...

simple physical model for the simultaneous rationalisation of melting points and heat capacities of ionic liquids

Paul Joseph Dyson

The anal. of potential energy surfaces of ion pairs within the framework of an anharmonic oscillator model allows rationalization and prediction of m.ps. (Tmp) and heat capacities (Cp) of ionic liqs. (ILs) comprising di- and trialkylimidazolium or tetraalk ...

BH4- Self-Diffusion in Liquid LiBH4

Philippe Mauron, Pascal Martelli

The hydrogen dynamics in solid and in liquid LiBH4 was studied by means of incoherent quasielastic neutron scattering. Rotational jump diffusion of the BH4 - subunits on the picosecond scale was observed in solid LiBH4. The characteristic time constant is ...

Melting of Two-Dimensional Adatom Superlattices Stabilized by Long-Range Electronic Interactions

Wolf-Dieter Schneider, François Patthey, Marina Pivetta, Markus Ternes

The melting transition of Ce adatom superlattices stabilized by long-range substrate-mediated electronic interactions on Cu(111) and Ag(111) noble metal surfaces has been investigated by low-temperature scanning tunneling microscopy, density functional the ...

Climate change and natural hazards in the Grisons

Michael Lehning

On account of the current global warming, climate researchers warn of a possible increase in the frequency and magnitude of extreme weather conditions in the future. As an alpine canton, the Grisons are particularly exposed to such events. In the article, ...
