What is the most sensitive type of spectroscopy? Among instrumental techniques, fluorescence spectroscopy is recognized as one of the more sensitive. In fluorescence, the intensity of the emission of the sample is measured. The reason for the high sensitivity of fluorescence techniques is that the emission signal is measured above a low background level. What […]
Can transmission electron microscopes see DNA?
Can transmission electron microscopes see DNA? High-resolution transmission electron microscopy is combined with a novel preparation method, based on superhydrophobic sample control, to achieve a spatial resolution of down to 1.5Å. What are the advantages of transmission electron microscope? TEMs offer the most powerful magnification, potentially over one million times or more. TEMs have a […]
How do you test piezoelectric effect?
How do you test piezoelectric effect? To measure the effect of the piezoelectric effect on your systems, first make a baseline noise measurement in a stable environment (AC VRMS), and then make a baseline noise measurement in your testing environment. The difference in measurements will be due to both EMI and the piezoelectric effect. Where […]
Are oil stains permanent?
Are oil stains permanent? The problem with oil stains is that instead of leaving a brightly stained area, they tend to leave a slightly darkened area that may be difficult to notice right away. This area darkens with age unless it is removed quickly. And if the piece of clothing and oil stain dry, the […]
Is angular momentum is scalar?
Is angular momentum is scalar? Angular momentum is a vector quantity that represents the product of a body’s rotational inertia and rotational velocity about a particular axis. What is the value of angular momentum for F Orbital? The orbital angular momentum of f orbital electron is equal to (1)√3h/π What is the value of angular […]
How do you find the centrifugal force?
Where is critical listening used?
Where is critical listening used? We can be said to be engaged in critical listening when the goal is to evaluate or scrutinise what is being said. Critical listening is a much more active behaviour than informational listening and usually involves some sort of problem solving or decision making. What is critical listening Where do […]

Is there no noise in space?
Is there no noise in space? Unlike light, sound requires a medium to travel through. This simply means that in order to hear sound there has to be something for sound to travel through. In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this […]
