Energies, Vol. 7, Pages 8201-8216: Thermal Performance Evaluation of Two Thermal Energy Storage Tank Design Concepts for Use with a Solid Particle Receiver-Based Solar Power Tower

09.12.2014 | El-Leathy, Abdelrahman ; Jeter, Sheldon ; Al-Ansary, Hany ; Abdel-Khalik, Said ; Roop, Jonathan ; Golob, Matthew ; D ..., Energies, 2014

This paper presents the results of an extensive study of two thermal energy storage (TES) systems. The goal of the research is to make solar energy cost-competitive with other forms of electricity. A small-scale TES system was first built. The inner to outer layers were made of firebrick (FB), ...


Rational design and synthesis of an orally bioavailable peptide guided by NMR amide temperature coefficients [Biophysics and Computational Biology]

09.12.2014 | Conan K. Wang; Susan E. Northfield; Barbara Colless; Stephanie Chaousis; Ingrid Hamernig; Rink-Jan Lohman; Daniel S. ..., Proceedings of the National Academy of Sciences current issue, 2014

Enhancing the oral bioavailability of peptide drug leads is a major challenge in drug design. As such, methods to address this challenge are highly sought after by the pharmaceutical industry. Here, we propose a strategy to identify appropriate amides for N-methylation using temperature ...


[Report] Multidecadal warming of Antarctic waters

05.12.2014 | Sunke Schmidtko; Karen J. Heywood; Andrew F. Thompson; Shigeru Aoki, Science , 2014

Seawater temperature around Antarctica is rising as more warmer, deeper water moves toward the surface. [Also see Perspective by Gille] Authors: Sunke Schmidtko, Karen J. Heywood, Andrew F. Thompson, Shigeru Aoki


Force distribution affects vibrational properties in hard-sphere glasses [Physics]

02.12.2014 | Eric DeGiuli; Edan Lerner; Carolina Brito; Matthieu Wyart, Proceedings of the National Academy of Sciences current issue, 2014

We theoretically and numerically study the elastic properties of hard-sphere glasses and provide a real-space description of their mechanical stability. In contrast to repulsive particles at zero temperature, we argue that the presence of certain pairs of particles interacting with a small force ...


Charging-free electrochemical system for harvesting low-grade thermal energy [Applied Physical Sciences]

02.12.2014 | Yuan Yang; Seok Woo Lee; Hadi Ghasemi; James Loomis; Xiaobo Li; Daniel Kraemer; Guangyuan Zheng; Yi Cui; Gang Chen, Proceedings of the National Academy of Sciences current issue, 2014

Efficient and low-cost systems are needed to harvest the tremendous amount of energy stored in low-grade heat sources ...


Functional Activity of Plasmid DNA after Entry into the Atmosphere of Earth Investigated by a New Biomarker Stability Assay for Ballistic Spaceflight Experiments

26.11.2014 | Cora S. Thiel et al., PLoS ONE, 2014

by Cora S. Thiel, Svantje Tauber, Andreas Schütte, Burkhard Schmitz, Harald Nuesse, Ralf Moeller, Oliver Ullrich Sounding rockets represent an excellent platform for testing the influence of space conditions during the passage of Earth's atmosphere and re-entry on biological, physical and ...


Effects of temperature and precipitation variability on the risk of violence in sub-Saharan Africa, 1980-2012 [Social Sciences]

25.11.2014 | John O’Loughlin; Andrew M. Linke; Frank D. W. Witmer, Proceedings of the National Academy of Sciences current issue, 2014

Ongoing debates in the academic community and in the public policy arena continue without clear resolution about the significance of global climate change for the risk of increased conflict. Sub-Saharan Africa is generally agreed to be the region most vulnerable to such climate impacts. Using a ...


Ocean surface temperature variability: Large model-data differences at decadal and longer periods [Earth, Atmospheric, and Planetary Sciences]

25.11.2014 | Thomas Laepple; Peter Huybers, Proceedings of the National Academy of Sciences current issue, 2014

The variability of sea surface temperatures (SSTs) at multidecadal and longer timescales is poorly constrained, primarily because instrumental records are short and proxy records are noisy. Through applying a new noise filtering technique to a global network of late Holocene SST proxies, we ...


Energies, Vol. 7, Pages 7847-7856: Isolation and Characterization of New Temperature Tolerant Microalgal Strains for Biomass Production

25.11.2014 | Bleeke, Franziska ; Rwehumbiza, Vincent M.; Winckelmann, Dominik ; Klöck, Gerd, Energies, 2014

Microalgae exhibit great potential for biomass production. Although microalgae display an enormous biodiversity, surprisingly only 15 species are used for large scale production processes worldwide. The implementation of new production strains with good process-oriented properties, especially ...


Energies, Vol. 7, Pages 7816-7846: Performance Analyses of Renewable and Fuel Power Supply Systems for Different Base Station Sites

25.11.2014 | Lorincz, Josip ; Bule, Ivana ; Kapov, Milutin, Energies, 2014

Base station sites (BSSs) powered with renewable energy sources have gained the attention of cellular operators during the last few years. This is because such “green” BSSs impose significant reductions in the operational expenditures (OPEX) of telecom operators due to the possibility of on-site ...
