- B.
  
  Adhesion decreases friction
- C.
  
  Adhesion has no effect on friction
- D.
  
  Adhesion varies depending on the material
Correct Answer
A. Adhesion increases friction

Explanation
Adhesion between surfaces increases friction at the nanoscale. Strong adhesion forces between atoms or molecules lead to higher resistance to sliding motion. This adhesion-induced friction can be particularly significant at the nanoscale, where surface interactions dominate and adhesion forces become more pronounced. Therefore, adhesion plays a role in increasing friction in nanofriction systems.

Rate this question:
6.

Which factor has a significant influence on nanofriction in dry environments?
- A.
  
  Humidity
- B.
  
  Temperature
- C.
  
  Pressure
- D.
  
  Chemical composition
Correct Answer
A. Humidity

Explanation
Humidity has a significant influence on nanofriction in dry environments. Changes in moisture content can affect the interaction between surfaces and alter friction properties. When there is low humidity, surfaces may become drier and exhibit higher friction due to reduced lubrication and increased adhesion between contacting surfaces. Conversely, in more humid conditions, the presence of moisture can act as a lubricant, reducing friction and wear between nanoscale surfaces.

Correct Answer
C. To reduce power consumption in robots

Explanation
Understanding nanofriction is important for the field of robotics primarily because it can help reduce power consumption in robots. While improving robotic manipulations and enabling robots to operate in extreme environments are also important goals in robotics, the reduction of power consumption through the understanding of nanofriction directly contributes to achieving these objectives by allowing robots to operate efficiently and for longer durations on a single power source.

- A.
  
  Hydrodynamic lubrication
- B.
  
  Boundary lubrication
- C.
  
  Mixed lubrication
- D.
  
  Elastohydrodynamic lubrication
Correct Answer
B. Boundary lubrication

Explanation
Boundary lubrication involves the formation of a protective boundary layer of lubricant molecules or additives on the surfaces in contact, reducing friction and wear. This mechanism is particularly relevant in situations where the load and sliding speed are relatively low, such as at the nanoscale.

Explanation
Self-assembled monolayers (SAMs) are commonly used in nanofriction studies for modifying surface roughness. SAMs can be used to control and manipulate the surface properties of materials at the nanoscale. By altering the chemical composition and structure of SAMs, researchers can tailor the roughness and interactions of surfaces, which in turn can influence friction and adhesion behavior in nanoscale systems. SAMs are valuable tools for studying and controlling nanofriction by providing a means to engineer the properties of surfaces and interfaces.
