In the course of combined computational and mass spectrometry-based mechanistic studies, recently we came across rather unusual, if not unprecedented, effects of transition-metal ions and ligands when simple metal oxides or carbides are subjected to thermal gas-phase reactions with methane. Interestingly, Gedankenexperiments demonstrate how these effects can be modeled using oriented external electric fields (OEEFs), thus expanding their predicted role as smart reagents (Shaik et al., Nat. Chem., 2016, 8, 1091), and further suggesting that the OEEFs may be used in controlling the adsorption/desorption behavior of methane as well as serving as a tool to explore mechanistic features.

Mechanistic Insight into Peptidyl-Cysteine Oxidation by the Copper-Dependent Formylglycine-Generating Enzyme

Yao Wu, Cong Zhao, Yanzhuang Su, Sason Shaik, Wenzhen Lai

Summary: The copper-dependent formylglycine-generating enzyme (FGE) catalyzes the oxygen-dependent oxidation of specific peptidyl-cysteine residues to formylglycine. Our QM/MM calculations provide a likely mechanism for this transformation, suggesting the involvement of a triplet Cu-II-superoxide complex and a Cu-I-alkylperoxo intermediate. The results also indicate that the aldehyde oxygen of the final product originates from O-2.

Micelle-mediated multicomponent cross-coupling in water: general construction of 3-chalcogenylindoles

Xi He, Weili Song, Xuemin Liu, Jiamin Huang, Ruilong Feng, Shaodong Zhou, Jianquan Hong, Xin Ge

Summary: A sustainable and general multicomponent cross-coupling method for the synthesis of 3-chalcogenylindoles from indoles using aryl iodides and elemental sulfur under aqueous micellar conditions is developed. Elemental sulfur serves as an eco-friendly and easy-handling sulfur source, generating thiyl radicals. The synergic effect between Cu catalysts and micelles formed by the sugar-based surfactant GluM stabilizes thiyl radicals, enabling C-S coupling with readily available indoles through single-electron transfer. The aqueous micellar system can be recycled and reused with good yields and can also be extended to the conversion of elemental selenium.

How Can Static and Oscillating Electric Fields Serve in Decomposing Alzheimer's and Other Senile Plaques?

Surajit Kalita, Hagai Bergman, Kshatresh Dutta Dubey, Sason Shaik

Summary: Alzheimer's disease and other neurodegenerative diseases characterized by senile plaques are caused by the accumulation of s-amyloid peptides. This study investigates the behavior of these plaques in the presence of static and oscillating oriented external electric fields using molecular dynamics simulations. The results show that long-term disintegration of the plaques is desirable for therapeutic treatments. Furthermore, the use of oscillating oriented external electric fields leads to irreversible disintegration of the aggregated s-amyloid peptides.

[4Fe-4S]-Mediated Proton-Coupled Electron Transfer Enables the Efficient Degradation of Chloroalkenes by Reductive Dehalogenases

Xuan Zhang, Zikuan Wang, Zhen Li, Sason Shaik, Binju Wang

Summary: This study reveals that the proximal [4Fe-4S] cluster in the reductive dehalogenase PceA can facilitate a proton-coupled electron transfer process to quench the substrate radical. The participation of [4Fe-4S] in mediating a PCET process in RDases is unexpected, although it is well known in reducing Co(II). The Arg305 residue acts as an efficient proton donor for the PCET reactions in RDases.

Oxygen-coordinated low-nucleus cluster catalysts for enhanced electrocatalytic water oxidation

Jiapeng Ji, Yunpeng Hou, Shiyu Zhou, Tong Qiu, Liang Zhang, Lu Ma, Chao Qian, Shaodong Zhou, Chengdu Liang, Min Ling

Summary: This study investigates the oxygen evolution reaction (OER) activity of single-atom catalysts (SACs) and reveals that oxygen-coordinated atomic metal species exhibit unique catalytic properties due to the weaker M-O bond compared to the M-N bond. A series of metal-oxygen-carbon structured low-nucleus clusters (LNCs) were successfully anchored on the surface of multiwalled carbon nanotubes (M-MWCNTs) using a low-temperature gas transfer method. The synthesized Ni-MWCNTs electrocatalyst demonstrates excellent OER activity and stability under alkaline conditions, surpassing the performances of Co-MWCNTs, Fe-MWCNTs, and RuO2. Density functional theory calculations reveal that the oxidation of low-nucleus Ni clusters lowers the energy barrier of the OER rate-limiting step, making the OER process more energy-efficient. This study presents a novel versatile platform for large-scale manufacturing of oxygen-coordinated LNC catalysts.

Aryl selenonium vs. aryl sulfonium counterions in polyoxometalate chemistry: the impact of Se+ cationic centers on the photocatalytic reduction of dichromate

Mahender Singh, Aakash Yadav, Ranjit Singh, Chullikkattil P. Pradeep

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
