Combined in situ synchrotron micro X-ray diffraction and high-speed imaging on rapidly heated and solidified Ti-48Al under additive manufacturing conditions

Helena Van Swygenhoven, Steven Van Petegem, Christian Leinenbach

An in situ method to study the behavior of alloys during rapid heating and cooling combining laser heating with synchrotron micro X-ray diffraction and high-speed imaging is presented. Near-spherical Ti-48Al specimens were melted using a laser-based heatin ...

Light trapping in hematite-coated transparent particles for solar fuel generation

Ali Dabirian

Hematite (alpha-Fe2O3), due to its abundance and low-cost, is an attractive compound for photoelectrochemical splitting of water to produce hydrogen. However, one major obstacle preventing hematite from achieving the target efficiencies comprises its signi ...

Fast-moving dislocations trigger flash weakening in carbonate-bearing faults during earthquakes

Marie Estelle Solange Violay, Andrea Cavallo

Rupture fronts can cause fault displacement, reaching speeds up to several ms(-1) within a few milliseconds, at any distance away from the earthquake nucleation area. In the case of silicate-bearing rocks the abrupt slip acceleration results in melting at ...

Long-term pan evaporation observations as a resource to understand the water cycle trend: case studies from Australia

Jed Oliver Kaplan

Acceleration of the global water cycle over recent decades remains uncertain because of the high inter-annual variability of its components. Observations of pan evaporation (E-pan), a proxy of potential evapotranspiration (ETp), may help to identify trends ...

Design Exploration of Energy-Performance Trade-offs for Wireless Sensor Networks

David Atienza Alonso, Francisco Javier Rincon Vallejos, Nadia Khaled, Ivan Beretta

Wireless sensor networks (WNSs) are gradually evolving from a promising technology to a well-established reality in a large set of different domains. In order to fulfill the requirements of the specific scenario, a WSN must provide the right tradeoffs betw ...

Adaptive Carrier Tracking for Mars to Earth Communications During Entry, Descent, and Landing

Ali H. Sayed

We propose a robust and low complexity scheme to estimate and track carrier frequency from signals traveling under low signal-to-noise ratio (SNR) conditions in highly nonstationary channels. These scenarios arise in planetary exploration missions subject ...
