The numerical method is applied for qualitative analysis, noting that it represents a simplified model; the dish-like 3D structure and the micro/nanopores of the diatom frustules are not considered.
Although the shape and structure of the frustule vary from one diatom species to another, the frustule itself is a rather complex and well-organized structure capable of withstanding heavy loads.
"The evolutionary success and importance of diatoms to the Earth habitat means that their structure is optimal simultaneously in many respects—photonically, mechanically, biochemically—while ...
The results provided insights into the genome structure and evolution of F. cylindrus, as well as this diatom's role in the Southern Ocean. Diatoms are a common type of photosynthetic ...
which actually prevents the diatoms from breaking. The professor described it as, "[t]he presence of the holes delocalizes the concentrations of stress on the structure." Based from the results of ...
"The cell surface of diatoms is surprisingly diverse in its structure. We hadn't expected the colonisation by the different bacterial species to be so finely tuned to this structure," Simon explained.
and concluded the diatom wasn't using those genes. "But we started seeing very different morphologies," changes in cell structure, Halsey said, in this case related to sexual activity.
However, as Phys.org reports, Greer and her team believe that these holes also strengthen the diatom's structure, by stopping the spread of cracks once the organism comes under pressure.
Oku, 52, is thought to be one of only a few diatom artists in the world. Diatoms are so tiny that he has produced about 600 pieces in the past decade. But with his creations gaining newfound ...
This suggests that spatially- and temporally-variable interactions between climate-induced changes in the physical and chemical structure of lakes may drive diatom community changes, but this is ...
