Examples of ChLCs range from scarab beetle shells to liquid crystal displays. [2] Many natural molecules and polymers spontaneously form the cholesteric phase. ChLCs have been used to manufacture products ranging from smart paints to textiles to and sensors. Scientists often employ biomimicry to develop ChLC-based materials inspired by natural ...
In AmigaOS one can use the i2c.resource component [24] for AmigaOS 4.x and MorphOS 3.x or the shared library i2c.library by Wilhelm Noeker for older systems. Arduino developers can use the "Wire" library. CircuitPython and MicroPython developers can use the busio.I2C or machine.I2C classes respectively.
Monolayers of elongated cells have also been described to exhibit liquid-crystal behavior, and the associated topological defects have been associated with biological consequences, including cell death and extrusion. [53] Together, these biological applications of liquid crystals form an important part of current academic research.

A liquid-crystal display (LCD) in a smartphone Layers of a color TFT LCD. 1: Glass plates. 2+3: Horizontal and vertical polarizers. 4: RGB color mask. 5+6: Horizontal and vertical command lines. 7: polymer layer. 8: spacers. 9: thin film transistors. 10: front electrode. 11: rear electrode.
To focus on the reaction at the working electrode, the reference electrode is standardized with constant (buffered or saturated) concentrations of each participant of the redox reaction. [1] There are many ways reference electrodes are used. The simplest is when the reference electrode is used as a half-cell to build an electrochemical cell.
The only variable in this equation is the activity (or concentration) of the chloride anion. But since the inner solution is saturated with potassium chloride, this activity is fixed by the solubility of potassium chloride, which is: 342 g/L / 74.5513 g/mol = 4.587 M @ 20 °C.
First, an infected tissue sample is taken from the patient. Then an oligonucleotide complementary to the suspected pathogen's genetic code is chemically tagged with a fluorescent probe. The tissue sample is chemically treated in order to make the cell membranes permeable to the fluorescently tagged oligonucleotide.
