Microscopy
This type of microscopy uses a pinhole to eliminate out-of-focus light.
What is confocal microscopy?
What is fluorescence?
What is shear stress?
This type of electron is used detected to reveal the surface topography of a specimen with scanning electron microscopy (SEM).
What are backscattered electrons?
For fluorescence correlation spectroscopy (FCS), this type and number of molecules is desired.
What is a low concentration of bright molecules?
This type of microscopy results in a "halo"-like image.
What is phase contrast microscopy?
Using UV-vis spectroscopy, this type of plot can be used to determine the concentration of an unknown sample based on the absorbance or fluorescence of a series of known samples.
What is a standard curve (or calibration curve)?
This measurement is typically given as the stiffness of a material using rheology.
What is the storage modulus or G'?
Samples for scanning electron microscopy (SEM) must undergo what type of preparation to be observable?
What is sputter coating?
This technique could be used to measure the hydrodynamic radius of a sample.
What is dynamic light scattering? (FCS also correct)
This is the diffraction limit using visible light (give answer in nanometers).
What is the Abbe's Diffraction Limit, which is 200 nm.
This region of the electromagnetic spectrum is referred to as the "visible light" portion (give wavelengths).
What is 300-700 nm?
This is a property of a material that exhibits a difference in the amount of energy between a loading and unloading cycle.
What is hysteresis?
This type of electron is used to image samples using transmission electron microscopy (TEM).
What is direct beam or transmitted electrons?
What is the base peak?
Multi-color fluorescence microscopy requires that fluorophores used have this property.
What is a difference in emission spectra?
This region of the electromagnetic spectrum is used in nuclear magnetic resonance.
What is radio frequency?
This measurement refers to the behavior of a sample under constant strain over time.
What is stress relaxation?
This electron microscopy (SEM or TEM) provides higher resolution than the other.
What is TEM?
This type of operation mode for atomic force microscopy (AFM) is most commonly used for very hard samples.
What is contact mode?
This is one example of a super-resolution microscopy technique.
What is stimulated emission depletion (STED), stochastic (STORM), or structure illumination (SIM)?
This range region of an infrared spectrum (such as that obtained via Fourier-transform infrared spectroscopy or FT-IR) is typically used to identify most compounds.
What is the fingerprint region?
This point refers to the strain at which a material evolves from elastic deformation to plastic deformation.
What is the yield stress?
This secondary technique with SEM can be used to determine the elemental composition of a sample?
What is X-ray dispersive spectroscopy (EDS)?
What is shear-thickening?
