Of single-filament

Although intermediate filaments are not universally associated with the cytoskeleton, neutrophils possess intermediate filaments of the vimentin type. Vimentin is a rod-shaped molecule of relative molecular mass 57 kDa that readily polymerises under physiological conditions to produce stable filaments 10-12 nm in diameter. Intermediate filaments are more robust than microfilaments and microtubules, and in neutrophils they form an open network of single filaments in the perinuclear space.

Fig. 3. In vitro TIRF microscopy can also be employed to visualize complex protein-actin interactions. By attaching F-actin elongating proteins on beads (e.g., VASP, left) or on coverslips (e.g., formins, middle, processive elongation of single filaments can be visualized and analyzed. In these cases, filament buckling (white arrowdf can be observed due to the insertional assembly of actin monomers at the anchored filament barbed end (white circied). Moreover, the dynamic formation of complex structures such as filament bundles induced by VASP, fascin, or other actin-binding proteins in solution can be monitored in real time.

BS 4029, 1978, specifies a method of test for the measurement of tensile elastic recovery of all types of single filaments or fibers when subjected to tensile strain applied by a CRE type machine. No special pretreatments such as mechanical cycling or relaxation of internal stresses by immersion in boiling water are specified, although it is acknowledged that they may be required for some special purposes. The determination of elastic recovery from a given stress (specific stress) is not included. 

Figure 3 presents the superconducting transition temperatures for this series of single filament wires as a function of the applied tensile strain. The data in Fig. 3 are for a 15-hr heat treatment at 998 K. The Tc values represent the temperatures corresponding to 80% of the total inductive change to the normal state. Each...

Tedious measurements of the Weibull statistics of single-filament strengths are necessary for the determination of an accurate value of the fibre strength at the critical length afoft).

It has also been observed that the surface of the fibres influences the intensity of the hydration products deposition. The difference between alkali resistant glass fibres and CemFIL 2 fibres provided with a special coating has been observed, which resulted in different cementation of single filaments in a strand. 

Force generation by polymerization of single filaments is fairly well understood. However, our knowledge is much less complete concerning how forces are generated during assembly and...

Different kinds of porosity can be present and measured in polymer nanofiber samples. Porosity can be a bulk property of a sample, namely a collective feature of polymer nanofibers assembly, non-woven, etc., or an internal property of individual nanofibers, or a surface property of either nanofiber-based coatings or of single filaments. These features impact on many properties of nanomaterials, ranging from fluid diffusion into and out of non-wovens or single nanofibers, to wettability, ability of drug delivery, of effectively exchanging bio-chemical signals, and so on.
