Isotopic pattern Isotopic Pattern

The average isotopic distribution of a given chemical compound can be calculated using the isotopic abundances.

We provide a calculation form here, with the help of which this isotope pattern is calculated.

For more information see: Isotopic Composition of a Compound.

Isotopes Updated! Isotopes and Nuclides: Updated!

Internetchemistry presents the data and properties of almost 5000 isotopes and nuclides in a new form.

In addition to a changed layout and improved display on mobile devices, the isotope data has also been rearranged: Tables with the isotopes of an element can be displayed - or the data for individual nuclides can be called up using a search form.

Take a look for yourself: Isotopes.

Ancistrolikokine E Ancistrolikokines

They are a substance class known for about 20 years and come from a liana from the African jungle.

A member of this Ancistrolikokine called natural product class is currently attracting attention: The variant E3 shown above is a promising drug candidate in the fight against certain forms of pancreatic carcinoma.

Atomic Weights Update

Atomic Weights - Update

The IUPAC has updated the standard atomic weights of 14 chemical elements.

The atomic weights of aluminum, cobalt, gold, holmium, manganese, niobium, praseodymium, protactinium, rhodium, terbium, thulium and yttrium have been revised.

Electron rivers

Rivers of Electrons

Usually, the movement of electrons in a real material is rather different from the flow of water in a river. However, in extraordinary materials like the metal oxide palladium cobaltate, "electron rivers" can exist, as predicted theoretically over fifty years ago and now demonstrated by scientists from the MPI CPfS [Image credit: MPI CPfS].

Mechanism for Radiation Damage Identified

Mechanism for Radiation Damage Identified

Heidelberg scientists examine electronic decay processes with the aid of quantum chemistry.

What exactly are the processes when x-ray photons damage biomolecules with a metal centre?
