Which of the following examples are in the nanometre scale (more than one answer apply):
-
A red blood cell
-
Carbon nanotube
-
DNA molecule
-
Virus
-
A pollen grain
-
An atom
Correct Answer(s)
A. Carbon nanotube
A. DNA molecule
A. Virus
A. An atomExplanation
The examples that are in the nanometre scale are carbon nanotube, DNA molecule, virus, and an atom. These entities are all extremely small and can be measured in nanometers. A red blood cell and a pollen grain, on the other hand, are larger in size and cannot be considered to be in the nanometre scale.Rate this question:

Using nanotechnology, can we make new structures that nature doesn’t have? Do you agree?
-
Yes, I agree
-
I disagree
-
I don't know
-
Maybe..sometimes.
Correct Answer
A. Yes, I agreeExplanation
Yes, I agree that using nanotechnology, we can make new structures that nature doesn't have. Nanotechnology allows us to manipulate matter at the atomic and molecular level, enabling us to create materials and structures with unique properties and functionalities that are not found in nature. By designing and engineering at such a small scale, we can create novel materials, devices, and systems that have applications in various fields such as electronics, medicine, energy, and more.Rate this question:

At the nanoscale, a material can have different properties compared to its bulk form. State true or false.
-
True
-
False
Correct Answer
A. TrueExplanation
At the nanoscale, materials can exhibit different properties compared to their bulk form. This is due to the unique characteristics that arise at the nanoscale, such as increased surface area, quantum effects, and size-dependent properties. These differences can result in altered physical, chemical, electrical, and optical properties, making nanomaterials highly desirable for various applications in fields like electronics, medicine, and energy. Therefore, the statement "At the nanoscale, a material can have different properties compared to its bulk form" is true.Rate this question:

A ring of gold is yellow. Is this statement correct?
-
Yes
-
No
-
Depends on its alloy
-
I'm not sure.
Correct Answer
A. Depends on its alloyExplanation
The statement "A ring of gold is yellow" depends on the alloy of the ring. Gold in its pure form is a yellow metal, but when it is used to make jewelry like rings, it is often mixed with other metals to increase its durability. These alloys can change the color of the gold, resulting in variations such as white gold or rose gold. Therefore, the color of a gold ring can vary depending on the specific alloy used in its composition.Rate this question:

Materials we currently use have some limitations, e.g. they can easily break. Using nanotechnology, can we create more flexible materials?
-
Yes
-
No
-
I don’t know
-
Sometimes this can happen.
Correct Answer
A. YesExplanation
Using nanotechnology, it is possible to create more flexible materials. Nanotechnology involves manipulating materials at the nanoscale level, which allows for the creation of materials with enhanced properties. By engineering materials at the nanoscale, it is possible to enhance their flexibility and durability, overcoming the limitations of traditional materials. Therefore, nanotechnology offers the potential to create more flexible materials that are less prone to breaking.Rate this question:

Nanomaterials are:
-
Very promising in many applications and toxicology studies are now underway in very promising in many applications and toxicology studies are now underway to assess their safety.
-
Have same properties than normal materials and do not require toxicology studies
-
Totally new materials with unique properties so we cannot test their safety
-
None of the above.
Correct Answer
A. Very promising in many applications and toxicology studies are now underway in very promising in many applications and toxicology studies are now underway to assess their safety.Explanation
Nanomaterials are considered to be very promising in many applications. However, due to their unique properties and potential risks, toxicology studies are currently being conducted to assess their safety. This suggests that although nanomaterials have great potential, their safety is still being evaluated to ensure their suitability for various applications.Rate this question:

There are some questions regarding the ethical and social implications of nanotechnologies. What do you think?
-
Technology development should not be influenced by ethical and ethical questions.
-
Technology development should take into consideration social and ethical questions.
-
I don’t know
Correct Answer
A. Technology development should take into consideration social and ethical questions.Explanation
The correct answer states that technology development should take into consideration social and ethical questions. This means that when developing new technologies, it is important to consider the potential ethical and social implications that may arise. This is because technology can have a significant impact on society and individuals, and it is necessary to ensure that these impacts are positive and do not cause harm. Considering social and ethical questions helps to promote responsible and sustainable technology development.Rate this question:
