Impact compression properties of artificial cemented sand ...

In order to explore the mechanical properties of rock with deep in-situ stress under explosive impact, cemented sand material (artificial material) instead of rock was used to carry out impact dynamics test under the condition of confining pressure. The experimental results show that the stress-strain curve of cemented sand specimens tested by triaxial impact compression changes significantly ...

Sandstone Formation. Formation of the sandstones are cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays, and silica. Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to 2 mm (0.0025–0.08 inches).

Artificial Photosynthesis - an overview ScienceDirect Topics

Artificial photosynthesis is a process that mimics a very famous biochemical reaction: natural photosynthesis. The artificial photosynthesis system includes an enzyme bed reactor to fix CO 2 in the air (or any other source needing CO 2 to be removed). This reactor is fueled by hydrogen energy and bioelectric transducers.
