An atomic spectrum is a graph depicting the intensity of photons absorbed or emitted (luminescence and fluorescence) by atoms in relation to photon energy (typically expressed in terms of wavelength), which can offer relevant information regarding the chemical composition of samples. ...
The flexibility of sputter-sectioning, in combination with the principal advantages of SIMS technique, such as large dynamic range both in the mass separation and detection systems, enables the SIMS technique to be extremely sensitive for the quantitative analysis of solid surfaces and thin films. With optimized experimental conditions, like extremely low primary beam current (down to ~ 10 nA) ...
The iGEM (International Genetically Engineered Machine) Competition is an annual event in synthetic biology. Teams participating in iGEM typically spend several months conducting research, designing their projects, and building their biological systems. These projects can range from addressing real-world problems in areas such as healthcare, environmental sustainability, and manufacturing, to ...
