Nanometer-sized thin films of small organic molecules are widely used in applications ranging from organic electronics and pharmaceuticals to coatings and nano-imprint lithography. Studies show that properties of these nanometer-sized thin films deviate strongly from their bulk counterparts, possibly due to enhanced s…
Amyloid fibrils spontaneously formed by the aggregation of a diverse class of polypeptides and proteins are the hallmarks of numerous neurodegenerative diseases (e.g. Alzheimer’s disease and Parkinson’s disease) and nonneuropathic localized diseases (e.g. Type II diabetes). Among those proteins, amyloid-beta (Aβ) pept…
Dentre as atividades realizadas pelas indústrias metalúrgicas, destaca-se o forjamento, onde o aço é processado em prensas sob altas temperaturas, resultando na conformação do mesmo no formato desejado. Durante o forjamento, é necessária a aplicação de um lubrificante sobre a peça a fim de reduzir o atrito metal-metal…
This work comprises three novel applications of in situ- and meteoric-produced beryllium-10 (Be-10) in East Antarctica. Sampled deposits cover a wide spatiotemporal transect through the Dry Valleys, from an inland, middle elevation location of Quaternary age, to a mid-valley, high elevation location of Miocene age, an…

The chemical looping partial oxidation process is developed for the efficient conversion of gaseous and solid fuels into syngas via partial oxidation.The chemical looping partial oxidation process converts the fuels into high purity syngas with flexible H2:CO ratio that is suitable for downstream fuel or chemical synt…
Nuclear power has been an important part of the electricity generatingin Sweden in almost half a century. However, the use of nuclear powerraises many complex issues such as economy, accident risks, andradioactive waste management and storage. Nuclear power has thereforebeen debated intensively in Sweden as in many ot…

In this study, a detailed chemical kinetic database of NO/ CO/ O2 surface reaction on Rh/ Al2O3 has been constructed based on the measurements of gaseous / surface species. The gaseous species at the upstream and downstream of the monolithic catalyst were identified by FTIR, while the surface species on the powder cat…
The spin Hamiltonian parameters (SHPs) (g factors and zero-field splittings (ZFSs) D and E) and the local structure for Cr3+ in K2PdCl4 single crystal are theoretically investigated from the perturbation calculations of the SHPs for an orthorhombically distorted octahedral 3d3 cluster. The impurity Cr3+ is found not t…
The invention of pseudopotential-density functional theory to solve for the electronic structure of materials is one of the major successes of modern computational physics. A code based on this formalism was used to solve for the electronic structure of systems with limited dimensionality. The code solves for the elec…
Extracellular matrix is the microenvironment which interacts with cells to regulate their activities. Understanding the complexity and the function of cell niche is crucial for future development of cell therapy and regenerative medicines. The extracellular matrix contains a lot of signals, such as the biological and…
Miniaturization and performance improvements are driving the electronic industry to shrink the feature size of superconductor devices. Several important questions arise from this development. For example, how small can some devices be fabricated? How will it affect the device performance? Can new operating principles…
In the recent Correspondence, Professor Henrik Grönbeck made several comments on the recently developed grand unified model (GUM), in particular using the ligand-protected gold cluster [Au25(SR)18]1− as an example. We noted that the latter cluster can be viewed as belonging to a special group of ligand-protected gold…
A variety of room temperature ionic liquids have been synthesized and applied to various \nreactions. Four of these ionic liquids were prepared in a chiral manner: [1-butyl-3- \nmethylimidazolium][L-lactate], [1-butyl-3-methylimidazolium][D-lactate], [1-butyl-3- \nmethylimidazolium][(1S)(+)-10-camphorsulfonate], and […
En el presente trabajo, evaluamos la prefactibilidad de la implementación de una fábrica \nproductora de envases termoformados de tereftalato de polietileno PET, estableciendo su \nviabilidad técnica, económica y de mercado, considerando un crecimiento del mercado de \nenvases rígidos y empresas competidoras que tiene…

Background. In the article the possibilities of CMAS (Coupled Multielectrode Array Sensors) method for corrosion control are considered and the results of 24-day comparative experiment, in which along with this method there were used method LPR, gravimetry and laser microscopy of the sample surface are presented. The…
Mechatronics is an interdisciplinary area of engineering that combines mechanical engineering, electrical engineering and information technology. The development methodology for mechatronic systems supports the creation of innovative solutions, improving the reliability and ability of products and reducing their costs…
