We report a recent breakthrough to control profile angle for SiO2 Deep Anisotropic Dry Etching (SDADE). Our study reveals that gas residence time is the key parameter to control profile angle. Moreover, we show that it is possible to control profile angle, ...
The energy efficiency of an industrial hydrogen production process using steam methane reforming (SMR) combined with the water gas shift reaction (WGS) is analyzed using process integration techniques based on heat cascade calculation and pinch analysis wi ...
Nowadays, most of the natural gas conversion systems available on the market for bifuel vehicles are based on the venturi principle or on the continuous injection principle for the carburation of the engine. Even if the driveability of these systems is sat ...
The title of this paper, “Against the Odds - Switzerland and the Emergence of NGV’s”, written some time ago reflects an expectation based on test results and considerable market interest. Unfortunately at the time of writing Switzerland is still awaiting t ...
Significant advancements in the experimental analysis of soils and shales have been achieved during the last few decades. Outstanding progress in the field has led to the theoretical development of geomechanical theories and important engineering applicati ...
We empirically test the role of membership rules and voting schemes for climate change coalitions with the STAbility of COalitions model (STACO). The model comprises twelve world regions and captures long-run effects of greenhouse gas accumulation. We appl ...
Zeolites are one class of porous materials that are currently being explored for sepn. applications in the aim of reducing environmentally harmful carbon dioxide (CO2) from the combustion of fossil fuels. The several archetypical zeolites being employed or ...
The European Project for Ice Coring in Antarctica Dome ice core from Dome C (EDC) has allowed for the reconstruction of atmospheric CO2 concentrations for the last 800,000-years. Here we revisit the oldest part of the EDC CO2 record using different air ext ...
The energy efficiency of an industrial hydrogen production process using steam methane reforming (SMR) combined with the water gas shift reaction (WGS) is analyzed using process integration techniques based on heat cascade calculation and pinch analysis wi ...
The analysis of natural hydraulic networks over a wide range of scales,:allowed by modem digital mapping technology, reveals extraordinary diversity of natural forms, and yet deep regularity and symmetry, regardless of geology, climate, vegetation or expos ...
