What are the advantages and disadvantages of a scanning tunneling microscope?
STM AdvantagesSTMs are helpful because they can give researchers a three dimensional profile of a surface, which allows researchers to examine a multitude of characteristics, including roughness, surface defects and determining things about the molecules such as size and conformation. Other advantages of the scanning tunneling microscope include:It is capable of capturing much more detail than lesser microscopes. This helps researchers better understand the subject of their research on a molecular level.STMs are also versatile. They can be used in ultra high vacuum, air, water and other liquids and gasses.They will operate in temperatures as low as zero Kelvin up to a few hundred degrees Celsius.STM DisadvantagesThere are very few disadvantages to using a scanning tunneling microscope. The two major downsides to using STMs are:STMs can be difficult to use effectively. There is a very specific technique that requires a lot of skill and precision. STMs require very stable and clean surfaces, excellent vibration control and sharp tips.STMs use highly specialized equipment that is fragile and expensive.PriceThe electronics required for an STM are extremely sophisticated as well as very expensive. Low cost and relatively low quality STMs start at approximately $8,000 but some people have actually built their own amateur STMs for much less than that amount.However, professional quality STMs can range anywhere from $30,000 to $150,000 depending on the manufacturer and the extra parts included.ManufacturersIf you are interested in buying a scanning tunneling microscope, there are several reputable manufacturers from which you can make a purchase. STM manufacturers include:Nanosurf is a company that specializes in manufacturing both AFM and STMs. The company's primary STM is called the Nanosurf easyScan 2 STM. You can also buy upgrades and customize this STM to your specific needs.RHK Technology is another major manufacturer of scanning probe microscopes, including STMs. RHK Technology was founded in 1981 and has since become a leader in SPM manufacturing.
What is stealth technology?
Stealth technology is special technology to hide from radar which means the plane doesnt exist on a radar but stealth technology is expensive
How does physics affect the development of technology?
Because the physics optimistic the technology without physics there can be technology.
Why physics is the basis of technology?
physics is the basis of technology
Why physics and technology combined?
Physics tells you how to do something and technology does it!
What are problems faced by researchers in developing countries?
poor technology that facilitates saving of the collected data
What form of technology first allowed researchers to confirm that the Mid-Atlantic Ridge exists?
SONAR
Why researchers say that the fpr 3dtv is a new generation 3dtv According to the researchers FPR 3DTV is a new generation 3DTV.Why they say so?
The researchers in question are likely to be LG staff who are paid to support the idea of passive 3D technology. It is hardly a new generation of 3D as it is based on 3D movie technology that has been in use for decades. LG have chosen to use this older technology rather than the latest active 3D adopted by other manufacturers.
Life science based technology in healthcare?
By combining advanced technology with pharmaceutical improvements, researchers believe they can make the diagnosis process even better.
What does the term alkon mean?
Alkon is a family name. The asteroid 11169 was discovered by researchers at the Massachusetts Institute of Technology and named after a student's grandfather.
What is the role of cosmids in recombinent DNA technology?
Cosmids allow you to insert DNA sequences (genes) into the genome of a bacteria, much like a plasmid. Cosmids in recombinant DNA technology, however, utilize phage (bacterial viruses) to enable researchers to insert DNA sequences of genes with up to 44,000 base pairs, while normal plasmids are only able to efficiently carry 10,000 base pairs. This allows researchers to insert more complex genes into bacteria as well as increases the efficiency with which researchers can make genomic libraries of more complex organisms.
How do science and technology offer Africans hope for the future?
Researchers have worked to save the important cassava crop, which was threatened by insects, about (200) two-hundred million Africans depend on cassava as their main source of calories. Also scientist are working with farmers to stop soil erosion. And, researchers have curbed tropical diseases
How has technology helped historians understand the reasons for King Tutankhamen’s death?
MRI technology, cat scans, and a continuing advancement in DNA technology.
Does a company save money by outsourcing technology-bases research?
They can save money that way. They can pay fees for a short time instead of hiring researchers full time.
What is Internet 2?
Internet 2 could mean one of a few things:The actual name of an existing corsortium of technology leaders, researchers, and academics.The concept of a faster better Internet.
Is there other life on other galaxies?
it is not yet decided. many researchers claim there is but no one knows yet. we are increasing today's technology to see if we can get more fuel in the space ships tanks.
What is the connection between computers and early education?
Some researchers claim that children introduced to computers at an early age gives them a head start in a world where technology rules. However, some researchers argue that computers can ruin a child's imagination with mindless games or steal their innocence because of inappropriate adult material on the internet, which is sometimes difficult for even an adult to avoid.
