Influence of Thermal Cycling on Friction, Wear, and Damage Evolution of Fused Deposition Modeling of 3D‐Printed Glass Fiber Reinforced Polylactic Acid Composites

open access: yesPolymer Composites, EarlyView.
Schematic illustration of the experimental procedure of the specimens. ABSTRACT This research work investigated the effect of the cyclic thermo‐hygrometric aging regime between −20°C and +40°C with 0–400 cycles on the reciprocating tribological properties of fused deposition modeling (FDM) printed polylactic acid (PLA) and the same material reinforced ...

Petrography and shock-metamorphic features of impact breccias from the Xiuyan impact crater

open access: yes, 2022
Impact breccia is a unique rock type that formed during the meteorite impact process and it is an ideal sample for the studies on the formation process of impact crater, dating impact craters, and shock effects in minerals and rocks.

On the detection of the Wilkes Land impact crater

open access: yesEarth, Planets and Space, 2018
The definitive existence of a giant impact crater, two times larger than the Chixulub crater in the Yucatan peninsula, from an extraterrestrial origin, 1.6 km beneath Wilkes Land, East Antarctica, remain controversial.

Erosion Resistance Enhancement in Epoxy Composites by Recycled Rubber: Effect of Rubber Type

open access: yesPolymer Engineering &Science, EarlyView.
Erosion resistance enhancement in epoxy composites by recycled rubber. ABSTRACT Epoxy‐based materials have low erosion resistance due to their brittle nature, and toughness modification stands out for enhancing it. At this stage, the use of waste rubber as a reinforcement component in the composite system is of interest due to its role in providing ...

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Numerical modelling of large impact crater collapse

open access: yes, 2002
This thesis addresses the important geologic question of how large impact craters are formed. The approach of the research described in this thesis has been to study impact crater formation using the only feasible method of simulating such a rarely ...

Identifying and Interpreting Stratification in Sedimentary Rocks on Mars: Insight from Rover and Orbital Observations and Terrestrial Field Analogs [PDF]

open access: yes, 2013
Sedimentary rocks on Mars provide insight into past aqueous and atmospheric processes, climate regimes, and potential habitability. The stratigraphic architecture of sedimentary rocks on Mars is similar to that of Earth, indicating that the processes ...
