Various medical devices (such as catheters and guide wires) need hydrophilic coatings to reduce friction for maneuvering through blood vessels. They did so by studying hydrophilic, lipophilic, free-soluble and insoluble-bound phenolic extracts, using a lipoxygenase/4-nitroso-N,N-dimethylaniline (LOX/RNO) technique.
The clock rate typically refers to the frequency at which a chip like a CPU(central processing unit), one core of a multi-core processor, is running and is used as an indicator of the processor's speed. It is measured in the SI unit hertz.
In other words, the clock speed (sometimes referred to as the clock frequency or clock rate) of the processor is a kind of certification telling us how often we can give it instructions and still have failure-free operations.
