Helical organic micro- and nanostructures are formed by a charge-transfer complex, cinchonidine-TCNQ. These unusual forms result from the chirality, the steric structure and specific interactions of cinchonidine molecules. These materials are semicon

Protons behave like electrons. This similarity leads to the concept of proton semiconductors, where water is treated as an intrinsic semiconductor. Water doped with acid becomes a protonic analog of an n-type semiconductor (with excess protons), whil

Water doped with H+ and HO− enables the formation of a protonic p–n junction, which works similarly to a typical, electron-based p–n junction, including light emission when electrically powered. In the model examined, polymer scaffolding mainta

Polyaniline doped with p-toluenesulfonic acid (PANI/PTSA) emits light in two different ranges owing to electron and proton excitations. The protons effectively compete with the electrons in the wet PANI/PTSA in capturing the electrical energy.

Experiments with the chemically generated proton gradient, have lead to fabricate the system which emits the light, when electrically powered, owing to proton current flow. A polymeric scaffold preserves the stability of the system and, at the same t

Contextualisation of the Early Iron Age hoard of bronze objects discovered in Gdynia-Karwiny, site 1
After the amateur discovery of a hoard of bronze ornaments (a kidney bracelet and two hollow ankle rings) in 2014 in a forest near Gdynia (Pomerania, northern Poland), the place was subjected to excavation. It turned out that in the nearest context o
