This article presents the results of technical and technological studies of the oil painting by the artist of German origin Werner Tübke “Hiroshima I" (1958). The creative heritage of the author has been little studied and represents scattered data on the technology of painting and artistic techniques. The aim of the work was to determine the artistic materials and painting technolo-gy described in his diaries, using the example of his only painting in Russia – “Hiroshima I". For this purpose, an integrated approach was used using non–invasive control methods - photo in the light of visible luminescence, infrared reflectography (IRR), radiography, portable X-ray fluorescence (XRF), as well as infrared-Fourier spectroscopy (FT-IR) and polarizing microsco-py using microprobes. As a result, the pigment composition of the painting layers was deter-mined, the painting technology was refined, and a previously unknown hidden portrait of Werner Tübke's father was revealed.

Supramolecular hydrogels have been extensively studied for environmental applications owing to their biocompatible, nontoxic, and cost-effective properties. Herein, a polydopamine-β-cyclodextrin-epichlorohydrin (PDA-β-CD-EP) supramolecular hydrogel was facilely prepared through one-pot polymerization using a molar ratio of dopamine (DA)/β-cyclodextrin (β-CD)/epichlorohydrin (EP) of 1/2/50. Compared with other hydrogels, the (PDA-β-CD-EP) supramolecular hydrogel can selectively adsorb malachite green from mixed dyes. The structure, surface morphology, and thermostability of the PDAβ-CD-EP supramolecular hydrogels were illustrated by FT-IR, SEM−EDX, and TGA-DTG, respectively. Interestingly, the PDA-β-CD-EP-2 supramolecular hydrogel exhibited excellent pH-responsive swelling behavior. The influences of the pH, adsorption time, dosage, and initial concentration were systematically studied. Under optimal conditions, the maximum adsorption capacity of the PDA-β-CD-EP-2 supramolecular hydrogel was 652.1 mg/g for MG according to the Langmuir fitting results, much higher than those of the other adsorbents. More importantly, the PDA-β-CD-EP-2 supramolecular hydrogel possessed good reproducibility, reusability, and biodegradability. Besides, the selective adsorption mechanism was proposed and proved, such as hole size and shape effect, electrostatic force, and host−guest interaction. Overall, this study could provide a method to prepare a PDA-β-CD-EP-2 supramolecular hydrogel as a biosorbent for wastewater remediation.

“…On the other side, the noninvasive detection of organic pigments by spectroscopic techniques is possible but hard to achieve when the original pigment has degraded or is present at a very low concentration. Mass spectrometry (MS) has contributed significantly not only to the identification of historical and modern organic pigments in artworks − but also to the characterization of the waxes, lipids, varnishes, and protein paint binders . However, it usually requires small samples of the artifacts to be consumed.…”
