MORPHOLOGICAL TYPES OF 254 RICH PF GALAXY CLUSTERS
We determined the morphological types for 254 rich galaxy clusters from the PF Catalogue of Galaxy Clusters and Groups. The data set contains the PF galaxy clusters, which have no ACO coinciding ones.

BST1047+1156: A (Failing) Ultradiffuse Tidal Dwarf in the Leo I Group
We use deep Hubble Space Telescope imaging to study the resolved stellar populations in BST1047+1156, a gas-rich, ultradiffuse dwarf galaxy found in the intragroup environment of the Leo I galaxy group.

X-RAY EMISSION AND ORIENTATION OF SELECTED PF GALAXY CLUSTERS
X-ray counterparts for 35 galaxy clusters contained in the PF catalogue of galaxy clusters and groups were found in XMM-Newton archive. 22 ones (all from ACO catalogue) have extended elliptic X-ray haloes appropriate for determination of orientation ...

Homochiral Self‐Sorting During Macrocycle Formation and their Chiroptical Properties
Imine condensation of C2‐symmetric chiral aldehydes with aliphatic amines results in 2 : 2 macrocycles lacking self‐sorting, whereas aromatic amines yield macrocycles with complete homochiral self‐sorting. These macrocycles exhibit unique chiroptical properties attributed to rigidification compared to the starting aldehydes.
