Atomic-Resolution Imaging of Small Organic Molecules on Graphene

Priti Kharel et al.

Summary: Here, we demonstrate atomic-resolution scanning transmission electron microscopy (STEM) imaging of light elements in small organic molecules on graphene. Our approach involves low-dose, room-temperature, aberration-corrected STEM to create high-quality composite images, with sufficient resolution to distinguish individual carbon and nitrogen atoms.

Atomic-number (Z)-correlated atomic sizes for deciphering electron microscopic molecular images

Junfei Xing et al.

Summary: With the development of atomic resolution transmission electron microscopy (AR-TEM), chemists can visually study the temporal evolution of molecular motions and reactions at the atomic level. However, experimental TEM images often differ from conventional molecular models, making them difficult to interpret. By introducing correlated atomic radii models, researchers can more easily estimate molecular structures from TEM images.

Ionization and electron excitation of C60 in a carbon nanotube: A variable temperature/voltage transmission electron microscopic study

Dongxin Liu et al.

Summary: There is increasing attention to the chemical applications of transmission electron microscopy, but it is often hindered by radiation damage. This study focuses on the radiolysis damage in organic matter and aims to provide fundamental information on the product structure, electron energy influence, and reaction kinetics. By studying the [2 + 2] dimerization of a van der Waals dimer [60]fullerene in a carbon nanotube, the researchers identify five reaction pathways that serve as mechanistic models of radiolysis damage. The results highlight the importance of variable-temperature and variable-voltage kinetic analysis in understanding radiation damage mechanisms.

Time-Resolved Atomistic Imaging and Statistical Analysis of Daptomycin Oligomers with and without Calcium Ions

Takayuki Nakamuro et al.

Summary: The study shows that the DP molecule has an intrinsic property of forming tetramers in water, which is enhanced by the presence of calcium ions. The dimer remains as the major species, and a face-to-face stacked structure based on dynamic imaging has been proposed.

Time-Resolved Atomistic Imaging and Statistical Analysis of Daptomycin Oligomers with and without Calcium Ions

Takayuki Nakamuro et al.

Summary: The study demonstrates that Daptomycin molecules have the ability to self-aggregate in water, with stronger aggregation in the presence of calcium ions. By using structural analysis and dynamic imaging techniques, it was found that DP molecules primarily form dimers and tetramers, with a proposed structure model.

Capturing the Moment of Emergence of Crystal Nucleus from Disorder

Takayuki Nakamuro et al.

Summary: Crystallization is the process of forming an organized solid through nucleation and growth of atoms or molecules, which is inherently stochastic. Experimental observation of NaCl nanocrystal nucleation and growth revealed both random fluctuations and controlled crystal formation at different temperatures. The role of graphitic surface and mechanical vibration in the process was experimentally highlighted.

Robust Cobalt Catalyst for Nitrile/Alkyne [2+2+2] Cycloaddition: Synthesis of Polyarylpyridines and Their Mechanochemical Cyclodehydrogenation to Nitrogen-Containing Polyaromatics**

Chang-Sheng Wang et al.

Summary: The study presents a simple and inexpensive catalytic system based on cobalt(II) iodide, 1,3-bis(diphenylphosphino)propane, and Zn for the [2+2+2] cycloaddition of various nitriles and diarylacetylenes to synthesize a broad range of polyarylated pyridines. DFT studies support a reaction pathway involving oxidative coupling of two alkynes, insertion of the nitrile into a cobaltacyclopentadiene, and C-N reductive elimination, leading to the synthesis of tetra- and pentaarylpyridines that can be used as precursors for nitrogen-containing polycyclic aromatic hydrocarbons.
