Small, EarlyView.Pulse‐duration‐controlled ultra‐short laser processing is shown to directly create binder‐free Fe‐enriched NiOx electrodes with tunable porosity, active‐site density, and oxygen‐evolution kinetics. Shorter pulses generate defect‐rich nanostructures that accelerate charge transfer, promote highly active NiFeOOH formation, and deliver durable alkaline ...

Earth and Space ScienceNear‐surface wind fields on Mars are profoundly modulated by complex topography, yet fine‐scale wind field characteristics remain poorly resolved for key geomorphological units such as deltas, valleys, and impact craters, due to the spatial constraints ...

steel research international, EarlyView.Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Minimal impact of spotted hyenas on livestock and endangered species in a prey‐rich ecosystem
Wildlife Biology, EarlyView.The diet of large carnivores is of great interest to conservation managers, as it can reveal the extent of human–carnivore conflict and the impact of carnivores on species of high conservation priority. Metabarcoding of environmental DNA can identify species and is often more reliable than observational or morphological methods, particularly when it ...

Pseudotachylite samples from the Charlevoix impact crater
Samples and their associated thin-section scans from the Charlevoix impact crater (Devonian aged). The samples were collected from the central point of the impact crater (Mont des Éboulements) up to 20 km from the central point.

Theoretical Research Progress in High-Velocity/Hypervelocity Impact on Semi-Infinite Targets
Shock and Vibration, 2015 With the hypervelocity kinetic weapon and hypersonic cruise missiles research projects being carried out, the damage mechanism for high-velocity/hypervelocity projectile impact on semi-infinite targets has become the research keystone in impact dynamics.

Journal of Animal Ecology, EarlyView.Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Global Policy, EarlyView.ABSTRACT The European Union's proposed Space Law aims to establish a unified approach for sustainable space activities across the EU. While the EU's satellite constellations contribute to sustainability efforts, they can also have negative environmental impacts.

Laboratory Studies of Hypervelocity Impacts on Solar System Analogues [PDF]
, 2015 Impact cratering and asteroid collisions are major processes throughout the Solar System. Although previous collision-related impact investigations exist (Flynn et al. 2015, Holsapple et al. 2002 and Burchell et al.
