Construction of three-dimensional interleaved protein hetero-superlattices in solution by cooperative electrostatic and aromatic stacking interactions

Hai Chen et al.

Summary: The study successfully fabricated protein assemblies with novel properties through the cooperative use of different types of noncovalent interactions. These assemblies efficiently self-assembled into predesigned interleaved hetero-superlattices, which exhibited high stability. By adjusting external stimuli such as pH and salt concentration, the size of the hetero-superlattices could be finely controlled, suggesting potential applications in biotemplating, light-harvesting, and encapsulation.

Solvent controlled aggregation behavior of peptide bond simulant N-methylacetamide and vibrational coupling splitting theory

Huigang Wang et al.

Summary: The study investigates the intermolecular C = O coupling in N-methylacetamide by analyzing Raman spectra in various binary mixtures. Results show that quantum frequencies and entanglement strength can be tuned by adjusting concentrations or selecting appropriate solvents. Solvents with good solvation properties or capable of forming H-bonds can facilitate the breaking of entangled dimers. The study has implications for structural identification, solvent-controlled processes, quantum communication, and thermodynamics teaching experiments.

The aggregation structure of a methanol/CHCl3 binary mixture investigated by polarized Raman spectroscopy and HNMR

Yufei Han et al.

Summary: The structural evolution of methanol in chloroform solvent was studied and a negative noncoincidence effect was observed. As methanol/CHCl3 was diluted by CHCl3, the vibration frequency of the C-O bond moved to lower wavenumbers, and the absolute value of the frequency difference also changed.

Understanding the self-ordering of amino acids into supramolecular architectures: co-assembly-based modulation of phenylalanine nanofibrils

Prabhjot Singh et al.

Summary: Amino acids are promising for the generation of functional materials due to their bio-compatibility and thermodynamic stability. The self-assembly of all naturally occurring amino acids, with their common zwitterionic motif, demonstrates vast functional diversity. Aliphatic chain amino acids have been discovered as potential candidates for modulating phenylalanine fibril toxicity, paving the way for the design and development of simple organic molecules with inherited self-assembling properties for functional nanomaterials.
