The highest density forms of customized urethane products are solid polyurethane elastomers.
"Most people don't think or realize that memory foam is made from petroleum," Mr. Alexander added, referring to the high-density form of polyurethane foam that has been popular in recent years.
All experiments used only the high-density form of bBR proteins (see the Supporting Information methods and Figures S1 and S2), unless noted otherwise.
At about −50°C, liquid water surpasses itself in strange behaviour and separates into two liquid phases of different density, a high density form and a low density form.
Limestone massifs with a high density of dolines form important karst aquifers in most of the Alps, often with groundwater circulating through deep karst conduits and water coming out of closely spaced springs with flow rates of over some cubic meters per second.
A model is presented for the active surface of Mo2C/Al2O3 and Mo2N/Al2O3 catalysts in which a thin layer of sulfided Mo exposing a high density of sites forms at the surface of the alumina-supported β-Mo2C and γ-Mo2N particles under HDS conditions.
These effects lead to the synthesis of photopolymerizable PEG-based hydrogels that exhibit highly compliant mechanical properties at high density capable of forming self-supporting structures.
Similarly, there exist 200 complexes among 551 known complexes with density value less than 0.1 in PPI Gavin 2. Furthermore, almost all complexes which are complete or have high density are of the form K3, while there are a large number of cliques of size 3 which are not complex.
The σ bonds are represented by lines, and the shaded areas are regions of high π-electron density formed by the overlapping of p orbitals of adjacent carbon atoms.
SEM image in Fig. 2e shows that just one-time printing forms a high density of nanoparticles with size of ~ 100 nm, which are similar as the ZIF-8 crystals prepared by the protein-induced synthesis (Fig. 1h, 2b).
Zones of Ca2+ signaling around and within the nucleus of smooth muscle cells have led some to suggest that clusters of lysosomes with high densities of RyR form in the perinuclear region forming physical junctions with the SR to comprise a trigger zone of Ca2+ [ 53].
