Article Abstract

Replacing a single carbon atom in C with a boron atom allows the functionalization of one additional carbon atom. Such a process involves little energy cost with regard to the structure of the fullerene. Two such replacements are required if the fullerenes are to act as "pearls on a string". This work shows trends for increasingly higher levels of carbon replacement with boron as well as hydrogenation, methylation, and ethylation of a subsequent carbon atom in such a boron-doped small fullerene. Additionally, dimers are shown to be stable, and the linking ethyl groups actually stabilize the overall structure more than when the ethyl groups are on the surface of the structure and are not serving as linkers. Such stringed fullerenes would certainly have applications to materials science if polymers could be made from these stringed pearls and would be suitable for neutron radiation shielding in spacecraft or spacesuits.

With the trend of heavy and inferior crude oil, the design of hydrodesulfurization (HDS) catalysts with excellent activity and high active metal utilization is an inevitable trend for the upgrading of refining technology. In this study, a highly dispersed Mo catalyst confined within nitrogen-doped porous carbon (xMo@NC) was prepared using an in situ encapsulation-pyrolysis approach and used in the HDS reaction of dibenzothiophene (DBT). The methods of XRD, HRTEM, HAADF-STEM, N physisorption, FT-IR, Raman, and XPS were used to carry out thorough microstructural characterization.

Gastric cancer (GC) is a malignant tumor originating from the epithelial cells of the gastric mucosa. The 5-methylcytosine (mC) modification refers to the addition of a methyl group to the fifth carbon atom of cytosine in RNA molecules. This study aimed to investigate the role of NOL1/NOP2/SUN domain (NSUN)6 in GC and its underlying molecular mechanisms.

Developing the efficient C─H bond activation carboxylation processes for furoic acid (FA) represents a critical technological challenge in achieving atom-economical synthesis of 2,5-furandicarboxylic acid (FDCA). Despite notable advancements in this field, the inherent contradiction between the high reactivity of furan rings and the chemical inertness of C─H bonds poses substantial technical bottleneck for achieving controllable C─H carboxylation under mild conditions. Herein, we report a high lattice-distorted MnOx catalyst with surface trench-like structures, wherein the Mn-O-conjugated configurations and electron-rich Mn cooperatively drive FA dehydrogenation and carbon radical reduction, inducing the free radical evolution process (FA→carbon-centered FA radical→FA carbanion), then coupled with solvent-polarized CO to accelerate the carboxylation process.

Multifunctional materials that simultaneously possess intrinsic magnetic and superhard properties, particularly those composed of light elements, have a wide range of applications in advanced sensors, shielding, durable devices, and other fields. However, research on the development and understanding of such materials remains limited. In this study, a series of 3D C covalent networks derived from the C fullerene precursor were theoretically designed.

Reaction of LZnI [L = BuC(N-DIPP), DIPP = 2,6-Pr-CH] with KC in the presence of cyclic (alkyl)(amino)carbene (cAAC) affords a stable radical complex [LZn(cAAC)] (3). Single-crystal structural analysis of 3 shows a short Zn─C bond and concomitant elongation of C─N bond within the cAAC ligand, indicating a significant π-backbonding from the metal to the cAAC ligand. EPR spectroscopy and DFT calculations reveal that the spin density is mainly localized on the carbenic carbon atom, with a small portion on the zinc center.
