Scanning thermal microscopy ( SThM) is a type of scanning probe microscopy that maps the local temperature and thermal conductivity of an interface. The probe in a scanning thermal microscope is sensitive to local temperatures – providing a nano-scale thermometer. Thermal measurements at the nanometer scale are of both scientific and ...
Dating back to the 1940s and continuing today, T-even phages are considered the best studied model organisms. Model organisms are usually required to be simple with as few as five genes . Yet, T-even phages are in fact among the largest and highest complexity virus , in which these phage's genetic information is made up of around 300 genes .
A graphical diagram depicting the in trans template dependant activity of terminal deoxynucleotidyl transferase. Loop1 is highlighted in red. Loop1 is highlighted in red. Polymerase μ and polymerase λ exhibit similar in trans templated dependant synthetic activity to TdT, but without similar dependence on downstream double-stranded DNA. [ 27 ]
v. t. e. Scanning probe microscopy ( SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope, an instrument for imaging surfaces at the atomic level. The first successful scanning tunneling microscope experiment ...
A scanning tunneling microscope ( STM) is a type of scanning probe microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer, then at IBM Zürich, the Nobel Prize in Physics in 1986. [ 1][ 2][ 3] STM senses the surface by using an extremely sharp conducting tip that ...
Type III secretion system. A transmission electron microscope image of isolated T3SS needle complexes from Salmonella typhimurium. The type III secretion system ( T3SS or TTSS) is one of the bacterial secretion systems used by bacteria to secrete their effector proteins into the host's cells to promote virulence and colonisation. [1] [2] While ...
Meteorological instrumentation. Galileo thermometer. Meteorological instruments (or weather instruments ), including meteorological sensors ( weather sensors ), are the equipment used to find the state of the atmosphere at a given time. Each science has its own unique sets of laboratory equipment. Meteorology, however, is a science which does ...
Nucleic acid thermodynamics is the study of how temperature affects the nucleic acid structure of double-stranded DNA (dsDNA). The melting temperature (T m) is defined as the temperature at which half of the DNA strands are in the random coil or single-stranded (ssDNA) state. T m depends on the length of the DNA molecule and its specific ...
