Hace 4 días · Since chemist Robert Bunsen and physicist Gustav Kirchhoff established the first instrumental analysis based on flame emission spectroscopy, spectrometry has played an important role in analyzing atoms and molecules (Casasanta, 2023; Davidson, 2011; Hennig, 2022).
Hace 3 días · Kirchhoff's circuit laws are two equalities that deal with the conservation of charge and energy in electrical circuits, and were first described in 1845 by Gustav Kirchhoff.
Hace 6 días · Gustav Kirchhoff (left) and Robert Bunsen (right) Theory: Photoelectric flame photometry, a branch of atomic spectroscopy is used for inorganic chemical analysis for determining the concentration of certain metal ions such as sodium, potassium, lithium, calcium, Cesium, etc.
Hace 4 días · Kirchhoff’s First Law, also known as the Current Law or Kirchhoff’s Junction Rule, states that the total current entering a junction in an electrical circuit is equal to the total current leaving the junction. This principle is a fundamental aspect of circuit analysis and is based on the conservation of electric charge.
Hace 3 días · Figure chiave nella storia dell’astrofisica includono scienziati come Gustav Kirchhoff e Robert Bunsen, che hanno gettato le basi dell’analisi spettrale, e Margherita Hack, una delle più famose astrofisiche italiane, nota per le sue scoperte sulle Cefeidi e per il suo ruolo nella divulgazione scientifica.

Hace 3 días · Rubidium was first discovered by the German chemists Robert Bunsen and Gustav Kirchhoff in 1861 through spectroscopic analysis of mineral samples. It is a relatively rare element in the Earth’s crust, occurring in trace amounts in minerals such as lepidolite, pollucite, and carnallite.
