Ultra-high temperature geothermal wells (>450 °C) have a large potential for increased energy yield as compared to conventional high-temperature geothermal wells (200-300 °C), but several research challenges must be resolved before robust operation in this temperature range can be achieved. In this study, yield- and tensile strength data for...

In the present work, the potential of polyPOSS-imide membranes designed for the purification of H2 from a coke gas (utilized in the steelmaking industry) is investigated. Aiming at upscaling the membrane fabrication, tubular single-channel and multi-channel membranes were prepared, using polyhedral oligomeric silsesquioxane (POSS) nanostructures...

A self-supporting sandwich panel facade system under fire is studied. First, a thermomechanical FE model, which comprises the complete facade system, and incorporates material degradation and geometrical nonlinear behaviour except for the insulation material and connections, is loaded by a fire temperature curve. Eurocode design rules then...

In this paper, we present a method to create a highly sensitive piezoelectric quasi 1–3 composite using a thermoplastic material filled with a piezoelectric powder. An up-scalable high-temperature dielectrophoresis (DEP) process is used to manufacture the quasi 1–3 piezoelectric polymer-ceramic composites. For this work, thermoplastic cyclic...

High temperature aquifer thermal energy storage (HT-ATES) can contribute to the integration of renewable energy sources in the energy system, the replacement of fossil fuel-based heat supply and the utilization of surplus heat from industrial sources. However, there is limited understanding on the drivers, barriers and conditions of HT-ATES...

We present a thin-film dual-layer bottom barrier on PI that is compatible with 350°C backplane processing for OLED displays. We demonstrate OLEDs that survive bending over 0.5 mm radius for 10.000x. Furthermore, we show compatibility of the bottom barrier with the backplane process by fabricating AMOLED displays on GEN1-sized substrates.

We present a thin-film dual-layer bottom barrier on polyimide that is compatible with 350°C backplane processing for organic light-emitting diode displays and that can facilitate foldable active-matrix organic light-emitting diode devices with a bending radius of <2 mm. We demonstrate organic light-emitting diodes that survive bending over 0.5...

High temperature ferroelectrics for thermally stable devices that can detect pressure and temperature are of great industrial interest. Here we describe composites of lead titanate (PT) particle-polyetherimide (PEI) polymers with stable dielectric and piezoelectric properties over a broad range of temperature and frequency. The reported...

This paper describes the gelation of highly concentrated graphene/polymer dispersions triggered by mild heating. The gel formation is only dependent on the concentration of graphene with 3.25 mg mL-1 as the minimum value for graphene network formation. The graphene gel is then utilized for the preparation of colloidally stable and highly...

Dimensional and phase changes of four candidate oxygen carrier materials for chemical looping combustion are investigated by dilatometry and high-temperature X-ray diffraction during four redox cycles. NiO/Ni2AlO4 does not exhibit significant dimensional changes during cycling, and it is shown that the support material also contributes to the...

The hot summer of 2007 in southeast Europe has been studied using two regional atmospheric chemistry models; WRF-Chem and EMEP MSC-W. The region was struck by three heat waves and a number of forest fire episodes, greatly affecting air pollution levels. We have focused on ozone and its precursors using state-of-the-art inventories for...

Solar cookers supply clean and sustainable energy for cooking and so limit the use of wood or charcoal. A new type of solar cooker is developed with a hot plate. The hot plate offers comfortable access to the food under preparation. The hot plate opens up the opportunity to generate small amounts of electricity with the help of a thermo electric...

The current paper determines whether the rate of the metal dusting reaction is kinetically or thermodynamically controlled at 600 degrees Celsius. This is done by varying the gas composition, specifically the CO partial pressure and the carbon activity, and comparing the degradation rates of alloy 800H samples. ©2011 by NACE International.
