A shadow-mask evaporated pyroMEMS igniter

Nico de Rooij, Danick Briand, David de Koninck

A reliable pyroMEMS igniter was successfully demonstrated based on shadow-mask evaporation of metal directly onto solid propellant drops. In this way, intimate contact between the fuel and the igniter was guaranteed. No visible degradation of the fuel was ...

Insights into the Origin of Cooperative Effects in the Spin Transition of [Fe(NH(2)trz)(3)](NO3)(2): the Role of Supramolecular Interactions Evidenced in the Crystal Structure of [Cu(NH(2)trz)(3)](NO3)(2)center dot H2O

Christine Neuhausen

The thermally induced hysteretic spin transition (ST) that occurs in the polymeric chain compound Fe(NH(2)trz)(3)(2) (1) above room temperature (T-c(sic) = 347 K, T-c(sic) = 314 K) has been tracked by Fe-57 Mossbauer spectroscopy, SQUID magnetometry ...

Kinetic Control in the Chiral Recognition of Three-Bladed Propellers

Natalie Renuka Banerji, Jérôme Lacour

The ion pair of the stereolabile C3-symmetric, i+o proton complex [1⋅H]+ of diaza-macropentacycle 1 and the configurationally stable Δ-TRISPHAT ([Δ-3]−) anion exists in the form of two diastereomers, namely, [Δ-(1⋅H)][Δ-3] and [Λ-(1⋅H)][Δ-3], the ratio of ...

Two-Phase Pressure Drops in Adiabatic Horizontal Circular Smooth U-Bends and Contiguous Straight Pipes (RP-1444)

John Richard Thome, Ricardo Lima

Curved channels in the form of bends are encountered in many industrial two-phase flow applications, such as U-bends in air-conditioning and refrigeration evaporators and condensers. For engineering design purposes, the evaluation of the pressure loss in t ...

Stenciled conducting bismuth nanowires

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Oscar Vazquez Mena, Katrin Sidler Arnet, Sam Neuser

Stencil lithography is used here for the fabrication of bismuth nanowires using thermal evaporation. This technique provides good electrical contact resistance by having the nanowire structure and the contact pads deposited at the same time. It has also th ...

Pore scale analyses of evaporation from porous media

Nima Shokri

Evaporation from porous media is a key process in the hydrologic cycles, waste isolation, biological and food processes and other engineering application. Drying rate and patterns in porous media are strongly influenced by transport properties of the mediu ...

Decomposition of copper concentrates at high-temperatures: An efficient method to remove volatile impurities

Christian Ludwig

The thermal decomposition of three synthetic copper sulfides (chalcocite (Cu2S), chalcopyrite (CuFeS2), and enargite (Cu3AsS4)) and two commercial copper concentrates has been studied on a thermobalance (T = 1173-1773 K) and an imaging furnace (T approxima ...

Characteristic lengths affecting evaporative drying of porous media

Dani Or

Evaporation from porous media involves mass and energy transport including phase change, vapor diffusion, and liquid flow, resulting in complex displacement patterns affecting drying rates. Force balance considering media properties yields characteristic l ...

Drying front and water content dynamics during evaporation from sand delineated by neutron radiography

Dani Or, Nima Shokri

Evaporative drying of porous media is jointly controlled by external ( atmospheric) conditions and by media internal transport properties. Effects of different atmospheric potential evaporative demand on observed drying rates were studied in a series of la ...
