Well, Nidum and Andy, I`m surprised how much you helped me, with your links I think I got all the theoretical and experimental information to properly interpret my fibres and understand their behaviour...I even found a freeware app, FiberApp, that runs with Matlab and should predict all the...
since the radius of curvature is small, it is possible that the bending can be appreciated only on long fibres, so maybe no different behaviour between short and long fibres...these fibres (short and long) are probably composed of 2-or more entwined filaments...my question is why they bend? and...
Here is a picture...on the right part there is a long fibre, with that constant bending, on the left part few small fibres, straight.
Thank you,
Andrea
Hello,
I`m studying amyloid fibres, which are filamentous proteins that intertwine between them (from 2 to 4 and more) and form fibres (2-20nm thick). I see that when that below a threshold length, the fibre is linear, beyond the threshold length, the fibre bend always with the same, constant...
Hello,
I quote from a paper: "...a solution of CuSO4 (1 mM) and NaAsc (2 mM) in 10 mM Tris buffer with 20% DMSO".
Does the molarities refer to the 80% volume of the Tris buffer or of the total volume (80% v Tris + 20% v DMSO)? For example, if I want to make 100 mL solution, I have to add...
