Cellular and polyhedral instabilities can exist individually or appear simultaneously in the inner flame.
However, controversy remains regarding the microstructure of anatase and rutile: do they interwoven forming heterojunction structure or exist individually?
Since rutile presents much higher resistances towards dissolution by LiOH than anatase, it is reasonable to find during hydrothermal reaction that the ratio of anatase to rutile (A/R) gradually decrease if they exist individually.
While other reviews exist individually for webs, silk, and spider evolution, we hope that the synthetic nature of this review will facilitate a more integrated approach by future investigators.
To date there is no gene delivery vehicle that contains all the desirable characteristics but they do exist individually in a variety of non-viral carriers, e.g. degradable, low toxicity, cell specific, relatively efficient and capable of delivering multiple genes.
Although wet silica gels and bacterial cellulose gels seriously crack and shrink, respectively, when they exist individually, synergic effects between the fragile silica gel skeleton and soft bacterial cellulose gel skeleton ensure structural integrity of the composite gels during ultrafast evaporative drying.
They might all be combined, or they can exist individually, making it fairly easy in the end to succeed in a macho world!
While it is not known whether they exist individually or as a complex in the native state, however, it is likely that in the native state this could be present as a complex and this is indeed apparent from solubility, at least in E. coli, of the complex.
In a control midgut, stem cells exist individually or (rarely) as doublets, together with their daughter EB cell.
However, although a certain global correlation exists, individually, it has not been observed to be linear and, in some cases, it can even be inverse [ 3].
