2. 1. Hydrogen Storage Materials : Design, Catalysis, Thermodynamics, Structure and Optics

   Author : Carlos Moysés Graça Araújo; Rajeev Ahuja; Ole Martin Løvvik; Uppsala universitet; []
   Keywords : Materials science; Hydrogen-storage materials; Density functional theory; Molecular dynamics; Catalysis; Thermodynamics; Optics; Materialvetenskap;

   Abstract : Hydrogen is abundant, uniformly distributed throughout the Earth's surface and its oxidation product (water) is environmentally benign. Owing to these features, it is considered as an ideal synthetic fuel for a new world energetic matrix (renewable, secure and environmentally friendly) that could allow a sustainable future development.

4. 2. Energy Storage Materials: Insights From ab Initio Theory : Diffusion, Structure, Thermodynamics and Design

   Author : Rafael Barros Neves de Araújo; Rajeev Ahuja; Graeme Henkelman; Uppsala universitet; []
   Keywords : Density Functional Theory; Defects Diffusion; Thermodynamics and Batteries.;

   Abstract : The development of science and technology have provided a lifestyle completely dependent on energy consumption. Devices such as computers and mobile phones are good examples of how our daily life depends on electric energy. READ MORE

5. 3. Computational Insights on Functional Materials for Clean Energy Storage : Modeling, Structure and Thermodynamics

   Author : Tanveer Hussain; Rajeev Ahuja; Caetano R. Miranda; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Molecular dynamics; Hydrogen storage; Chemisorption; Physisorption; Functionalization; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : The exponential increase in the demands of world’s energy and the devastating effects of current fossil fuels based sources has forced us to reduce our dependence on the current sources as well as finding cleaner, cheaper and renewable alternates. Being abundant, efficient and renewable, hydrogen can be opted as the best possible replacement of the diminishing and harmful fossil fuels. READ MORE

6. 4. Novel approaches in modeling of soil carbon : Upscaling theories and energetics

   Author : Arjun Chakrawal; Stefano Manzoni; Hyun-Seob Song; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Microorganisms; soil C cycling; spatial heterogeneity; energetics; thermodynamics; microbial metabolism; calorespirometric ratio; microbial traits; heat dissipation; microscale; Physical Geography; naturgeografi;

   Abstract : Soils contain more carbon (C) than terrestrial (above ground) and atmospheric carbon combined. Mismanagement of soil C could lead to increased greenhouse gas emissions, whereas practices leading to increased C storage would help mitigate climate change while improving soil fertility and ecological functions.

7. 5. Thermodynamics of Hydrogen in Confined Lattice

   Author : Xin Xiao; Hjörvarsson Björgvin; Max Wolff; Astrid Pundt; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermodynamics hydrogen superlattice;

   Abstract : Three of the most important questions concerning hydrogen storage in metals are how much hydrogen can be absorbed, how fast it can be absorbed (or released) and finally how strongly the hydrogen is bonded. In transition metals hydrogen occupies interstitial sites and the absorption as well as desorption of hydrogen can be fast. READ MORE
