Trends in today’s building society seem to lead towards a more sustainable society where energy efficiency and sustainability are seen as real parameters to take into consideration at both community planning and villa projects. Now that concepts like zero energy and passive houses will be part of the construction industry’s mainstream, the authors hope that the construction industry will take this
The aim of this work is to study the performance of nanoporous carbon membrane for hydrogen recovery from off-gas streams. The study is based on a rigorous mathematical model which can predict the performance of nanoporous selective surface flow (SSF) carbon membrane. Basically, the developed model is based on two transport mechanisms: the dusty gas flow through porous media and the surface adsorp
The DAΦNE electron-positron collider of the Laboratori Nazionali di Frascati of INFN is a worldwide unique low-energy kaon source, which is being used to produce and to study kaonic atoms by the SIDDHARTA collaboration. The X-ray measurements of kaonic atoms play an important role for understanding the low-energy QCD in the strangeness sector. Significant achievements have been obtained by the SID
We have performed a systematic computational study of the relative energies of possible protonation states of the FeMo cluster in nitrogenase in the E0-E4 states, i.e., the resting state and states with 1-4 electrons and protons added but before N2 binds. We use the combined quantum mechanics and molecular mechanics (QM/MM) approach, including the complete solvated heterotetrameric enzyme in the c
Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen avaiable for other organisms. It contains a complicated MoFe7S9C(homocitrate) cluster in its active site. Many computational studies with density-functional theory (DFT) of the nitrogenase enzyme have been presented, but they do not show any consensus-they do not even agree where the first four protons should be
selected photographs Dreams and creativity was the topic for the third category. Dreams can be individual and collective and shared by a whole generation, and they are often shaped by socio-economic realities of different times and places. Cities can be sites of dreams for migrants who move there but their dreams might not be fulfilled. Cities are also often seen as creative places as they attract

Popular Abstract in English Proteins are a big biological molecules that help cells to function. Proteins play important roles in all vital processes of the living cell, transporting molecules, speeding up chemical reactions, supporting structure of other proteins and the cell, helping the cell to move. Various disease-causing agents (e.g. bacteria and viruses) are constant threat to us. It is thMost drugs act on biomacromolecules. The Cost of developing new drugs is very high. A method to accurately predict binding affinities would be very useful. We have studied molecular mechanics with generalised Born and surface--area solvation (MM/GBSA) and alchemical free energy perturbation methods (FEP) for use in calculations of ligand binding energies. For the MM/GBSA method we have tested: Ca
The Philippines is an island nation in South East Asia consisting of more than 7 000 separate islands. The Philippines is the country in the world that is most often struck by tropical storm; every year between 6 and 9 typhoons hit land in the Philippines. In November 2013 the super typhoon Haiyan hit the nation, killing 10 000 people and causing massive destruction to parts of the infrastructure
What to do with CO2 ? Gadi Rothenberg Van 't Hoff Institute for Molecular Sciences, University of Amsterdam. CO2 emissions are a serious global problem. Hence the Paris Agreement and the COP meetings, where 118 countries agreed on reducing emissions and fighting climate change. Their main goals are keeping global warming below 2 °C, and reaching net-zero GHG emissions by 2050.[1] But is this reali

In this study, the use of energy carriers based on renewable energy sources in battery-powered electric vehicles (BPEVs), fuel-cell electric vehicles (FCEVs), hybrid electric vehicles (HEVs) and internal combustion engine vehicles (ICEVs) is compared regarding energy efficiency, emission and cost. There is the potential to double the primary energy compared with the current level by utilising vehi
In this paper we present an investigation of to perform simultaneous measurements of the D/H-ratio by coincidence measurements using proton-proton scattering and proton-deuteron scattering or deuteron-deuteron scattering and deuteron-proton scattering. This is performed with the use of a double sided silicon strip detector (DSSSD), which provides both position information and energy information. T
This chapter reviews methanol's properties as a fuel for marine use in general terms and then specifically for combustion engines and fuel cells. It discusses the different engine technologies being either investigated or demonstrated that allow methanol to be used in marine engines. Their potential in terms of power density, emissions, and efficiency, as well as their maturity are reviewed. The e
Heterogeneous catalysts based on Single Atom Alloys (SAA) play a significant role in numerous technical processes. The fundamental working principles of these systems, however, remain poorly understood, especially the aspects related to the nanoscopic nature of bimetallic particles and the associated structure-reactivity relationships. In this study, we developed for the first time well-defined SA
In order to contribute to reaching the climate goals of the future, power-to-heat (P2H) technologies are a possible solution. A heat pump (HP) or an electric boiler (EB) can be used to produce warm water by utilising cheap electricity from photovoltaic (PV) parks in the summer when there are many hours of sunlight. The warm water can then be stored until winter for use in district heating (DH) whe
We have succeeded in direct atomic scale imaging of the exterior surfaces of III-V nanowires by scanning tunneling microscopy (STM). By using atomic hydrogen, we expose the crystalline surfaces of InAs nanowires with regular InP segments in vacuum while retaining the wire morphology. We show images with atomic resolution of the two major types of InAs wurtzite nanowire surface facets and scanning
