OFF state. In the OFF state, i.e., when no electrical field is applied, the nematic liquid crystal molecules form a twisted configuration (aka helical structure or helix) between the two glass plates, G in the figure, which are separated by several spacers and coated with transparent electrodes, E 1 and E 2.
This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and in-plane switching subsequently remain the dominant LCD designs through 2006. [10]
Binding of biomolecules to the other side of this surface leads to a change in the refractive index which is proportional to the mass added to the sensor surface. In a typical application, one binding partner (the "ligand", often a protein) is immobilized on the biosensor and a solution with potential binding partners (the "analyte") is ...
The crystals may exist in one of two stable orientations ("black" and "white") and power is only required to change the image. ZBD Displays is a spin-off company from QinetiQ who manufactured both grayscale and color ZBD devices. Kent Displays has also developed a "no-power" display that uses polymer stabilized cholesteric liquid crystal (ChLCD ...
A 2017 image of a sneaker that recently resurfaced falsely claims to show which side of your brain is more dominant depending on the color you see.
Ocular dominance, sometimes called eye preference or eyedness, [1] is the tendency to prefer visual input from one eye to the other. [2] It is somewhat analogous to the laterality of right- or left-handedness; however, the side of the dominant eye and the dominant hand do not always match. [3]
For example, Cdk, or cyclin dependent kinase, is a major control switch for the cell cycle and it allows the cell to move from G1 to S or G2 to M by adding phosphate to protein substrates. Such multi-component (involving multiple inter-linked proteins) switches have been shown to generate decisive, robust (and potentially irreversible ...
Many cell types are capable of migration, such as leukocytes and fibroblasts, and in order for these cells to move in one direction, they must have a defined front and rear. At the front of the cell is the leading edge, which is often defined by a flat ruffling of the cell membrane called the lamellipodium or thin protrusions called filopodia.
