Vibrational assignments of cyclic dimers and inter-monomers of adenine relating FT-IR, FT-Raman and UV spectra with SQMFF and DFT calculations [PDF]
In this work, three different cyclic dimers and a tetramer of adenine taken from the experimental structure determined by X-ray diffraction have been studied by combination of experimental FT-IR, FT-Raman and UV–Visible spectra with hybrid B3LYP/6–311++G*

Evidence For An Unusual Kinetic Phenomenon In The Metallation Of Porphyrins [PDF]
, 1991 Reaction of copper(II) with water soluble porphyrins (H₂porph) in the presence of ethylenediamine shows an unusual and so far unreported kinetic phenomenon that can be explained in terms of supramolecular assembly formation apparently involving all ...

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization
Advanced Healthcare Materials, EarlyView.A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Self‐Cooling Molecular Spin Qudits
Advanced Materials, EarlyView.A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.
