We confine a nematic liquid crystal with homeotropic anchoring to stable toroidal droplets and study how geometry affects the equilibrium director configuration.
In contrast to the case of cylindrical confinement, we find that the equilibrium state is chiral—a twisted and escaped radial director configuration.
Furthermore, we find that the magnitude of the twist distortion increases as the ratio of the ring radius to the tube radius decreases; we confirm this with computer simulations of optically polarized microscopy textures.
In addition, numerical calculations also indicate that the local geometry indeed affects the magnitude of the twist distortion.
We further confirm this curvature-induced twisting using bent cylindrical capillaries.
All I make is fruit smoothies and this hunk can’t liquifie my fruit without me constsnatly removing the top to shake the contents around or adding extra water.
Food needs to be cut up extra small to prevent it all sitting above the blades as they spin. This replaced an old Breville that was way past its good days. Th Is is so powerful in comparison and really liquifies fruit as opposed to mushifying. I really love everything that this company produces, all of very good quality.
Very effective machine and easy to clean once it has done its work - good choice We have had this for years now and it has given perfect service. The blender, which I use now is very practical, very strong. It’s ok, not the sturdiest thing, really not the best with blending things, things really need to be broken down already for it to just finish the job.
Its fast, it instantly blitzes whatever we throw at it and its easy to clean. The most convenient for me, the blender has many functions that are very convenient to use . Buy some thing better, unless u just want to blend soup.
Its well made and just always works the same every time i reach for it - good deal! This Is a great blender in lots of ways with just one downfall.
Have been using this blender/mixer for a month now and we are quite happy with it. First up, I love the solid industrial style construction. I am taking one star off for the noise but other than that this is great This is a sold blender.
Its solid metal and feels way better than your average blender. The motor is powerful and it can easily puree veges.
