The Materials Genome is in action: the molecular codes for millions of materials have been sequenced, predictive models have been developed, and now the challenge of hydrogen storage is targeted. Renewably generated hydrogen is an attractive transportation fuel with zero carbon emissions, but its storage remains a significant challenge. Nanoporous adsorbents have shown promising physical adsorp...

Ethanol production at Lantmännen Agroetanol AB in Norrköping began in December 2000. The objective of this master’s thesis is to find and optimize factors affecting the yield of the liquefaction, a part of the upstream process. To measure successfulness of liquefaction it is desired that amount of non-solubilized starch is quantified, and hence a method for determination of non-solubilized star...

Earthquakes generate multi-directional ground motions, two components in the horizontal direction and one in the vertical. Nevertheless, the effect of vertical motion on site response analysis has not been the object of extensive research. The 2010/2011 Canterbury sequence of seismic events in New Zealand is a prime example among other earlier field observations strongly corroborating that the ...

The epidermis layer waste (ELW) and the inner layer waste (ILW) were removed from Phyllostachys pubescens bamboo, and the anatomical characteristics and chemical components of these wastes were comparatively investigated. Both the ELW and ILW were subjected to a microwave-assisted liquefaction process to evaluate the relationship between bamboo properties and liquefaction behavior. The results ...

This article reviews a method of hydrogen production based on partial non-catalytic oxidation natural gas in an original synthesis generator. The working principles the unit are similar to those liquid-propellant rocket engines. paper presents description operation and technical characteristics Its application creation small-scaled plants with capacity up 5–7 thousand m3/h is justified. Hydroge...

Abstract Magnetocaloric hydrogen liquefaction could be a ‘game-changer’ for liquid industry. Although heavy rare-earth based magnetocaloric materials show strong effects in the temperature range required by (77–20 K), high resource criticality of elements is major obstacle upscaling this emerging technology. In contrast, higher abundances light make their alloys highly appealing liquefaction. V...

The technological and technical possibility of deep processing coal by its liquefaction using the methods extreme mechanochemical physical effects has been determined; recommendations have developed for applied use obtained materials in heat power engineering. organic part solid mass prepared coal-oil suspension, which turned into a relatively heavy liquid, can be used as boiler or motor fuel, ...

The seismic performance of four pile-supported models is studied for two conditions: (i) transient to full liquefaction condition, i.e. the phase when excess pore pressure gradually increases during the shaking; (ii) full liquefaction condition, i.e. defined as the state where the seismically induced excess pore pressure equalises to the overburden stress. The paper describes two complementary ...

As the demand for eco-friendly energy increases, hydrogen and liquid storage technologies are being developed as an alternative. Hydrogen has a lower liquefaction point higher thermal conductivity than nitrogen or neon used in general cryogenic systems. Therefore, application of to systems can increase efficiency stability. This paper describes design analysis cooling system electric propulsion...
