Atomically thin nanopore membranes are considered to be a promising approach to achieve single base resolution with the ultimate aim of rapid and cheap DNA sequencing. Molybdenum disulfide (MoS2) is newly emerging as a material complementary to graphene du ...
Pt is the state-of-the-art anode catalyst in direct methanol fuel cells. Here we report that Ni2P promotes the activity and stability of Pt in electrochemical methanol oxidation. Nanoparticles of Ni2P and Pt were co-deposited on a carbon support and their ...
The limited fossil fuel resources and the increasing levels of greenhouse gases in the atmosphere are the driving forces in the research of alternative ways of energy production and storage. The use of solar energy is expected to grow as our society claims ...
The aim of this work was to provide a comprehensive surface characterization of rhodium and molybdenum mirrors exposed on the main chamber wall of JET during campaigns with carbon plasma-facing components. As determined using X-ray photoelectron spectrosco ...
The properties of single site-controlled InGaAsN quantum wires (QWRs)-both untreated and irradiated with atomic hydrogen-are probed by micro-magnetophotoluminescence spectroscopy. The strong anisotropy of the diamagnetic shift measured for different orient ...
A point defect relaxation peak has been observed in a ternary 18-carat gold alloy with the composition Au62.5Pd32.5In5. It shows a Curie Weiss dependence on the temperature, as is commonly observed for a Zener peak. However, the peak is absent in the binar ...
Bio synthetic natural gas (Bio-SNG) is being proposed as an alternative to the natural gas of fossil origin (NG) [1]. Bio-SNG consists mainly of CH4 (at least 95%mol), has a high heating value (e.g. 10 kWh/m3N), and respects the quality standards of the NG ...
Tantalum and hafnium carbides are classified as Ultra High Temperature Ceramics (UHTC) because of their extreme melting temperatures (above 3900 degrees C). Therefore, these materials can safely operate in the range of temperature that any other materials ...
Speciation analyses of an element allow obtaining information on the concentrations of its chemical forms present in specific environments. Chromium is largely distributed in industrial effluents often at acid pH, with the relevant oxidation states Cr (III ...
