Photothermal catalytic CO2 hydrogenation to methanol on Au/In2O3 nanowires
AbstractConverting CO2 into energy-rich fuels and high-value chemicals using solar energy is one of the sustainable solutions to mitigate reliance on fossil fuels, yet attaining the required conversion efficiency and selectivity to products such as methanol remains challenging. Here, we present In2O3 nanowires decorated with plasmonic Au nanoparticles with improved activity

What a Difference an Electron Makes: Structural Response of Saddle-Shaped Tetraphenylene to One and Two Electron Uptake
AbstractCyclooctatetraene (COT) and COT2− dianion are well-known as archetypical non-aromatic and aromatic systems, respectively. However, despite a wealth of studies the effect of one electron addition to the eight-membered ring remains equivocal. Herein, we report the first stepwise electron addition to tetrabenzo[a,c,e,g]cyclooctatetraene (TBCOT or tetraphenylene), accompanied

N2 Dissociation vs Reversible 1,2-Methyl Migration in PCNHCP Cobalt(I) Complexes in the Stereoselective Isomerization (E/Z) of Allyl Ethers
AbstractWith growing efforts pushing toward sustainable catalysis, using earth-abundant metals has become increasingly important. Here, we present the first examples of cobalt PCNHCP pincer complexes that demonstrate dual stereoselectivity for allyl ether isomerization. While the cationic cobalt complex [((PCNHCP)Co)2-μ-N2][BAr4F]2 (3) mainly favors the Z-isomer of the enol

Constraining Violating Nucleon-Nucleon Long-Range Interactions in Diatomic eEDM Searches
AbstractThe searches for violating effects in diatomic molecules, such as and ThO, are typically interpreted as a probe of the electron’s electric dipole moment ( ), a new electron-nucleon interaction, and a new electron-electron interaction. However, in the

Suspension Bead Loading (SBL): An Economical Protein Delivery Platform to Study URM1’s Behavior in Live Cells
AbstractUniquely modified synthetic proteins are difficult to produce in large quantities, which could limit their use in various in vitro settings and in cellular studies. In this study, we developed a method named “suspension bead loading” (SBL), to deliver protein molecules into suspended living cells using glass beads, which significantly reduces the amount of protein

Nitrogen-Terminated Milled Nanodiamond Surfaces by Plasma Exposure
AbstractThis study investigates surface modifications of hydrogen-terminated milled nanodiamond (H-MND) drop-cast films by microwave (MW) and radio frequency (RF) nitrogen plasma exposures. The RF(N2) damaging plasma treatment results in the highest nitrogen adsorption (∼7.5 at. %) followed by MW(N2) (∼4.2 at. %) and RF(N2) nondamaging (∼3.8 at. %) plasma treatments. Upon MW(N2)

Carbon Dioxide Sequestration Through Mineralization from Seawater: The Interplay of Alkalinity, Ph, and Dissolved Inorganic Carbon
AbstractMarine carbon dioxide removal technologies rely on the equilibration of the seawater with atmospheric CO2, where a pH increase can facilitate carbon dioxide removal either through increased absorption capacity of CO2, or precipitation of minerals. Here, we focus on explicitly defining the governing factors that influence seawater alkalinity with respect to

Identifying band structure changes of FePS3 across the antiferromagnetic phase transition
AbstractMagnetic 2D materials enable novel tuning options of magnetism. As an example, the van der Waals material FePS3, a zigzag-type intralayer antiferromagnet, exhibits very strong magnetoelastic coupling due to the different bond lengths along different ferromagnetic and antiferromagnetic coupling directions enabling elastic tuning of magnetic properties. The likely cause

Correlative in situ analysis of the role of oxygen on ammonia electrooxidation selectivity on NiOOH surfaces
AbstractThe electrochemical ammonia oxidation reaction (AOR) offers a promising pathway for environmental remediation, energy conversion, and the production of value-added chemicals. Although NiOOH shows potential as an efficient catalyst for AOR, the underlying mechanism and the influence of the concurrent oxygen evolution reaction (OER) are not yet fully understood. Here, the

Towards Catalytic Fluoroquinolones: From Metal-Catalyzed to Metal-Free DNA Cleavage
AbstractA library of eight new fluoroquinolone-nuclease conjugates containing a guanidinoethyl or aminoethyl auxiliary pendant on the 1,4,7-triazacyclononane (TACN) moiety was designed and synthesized to investigate their potential as catalytic antibiotics. The Cu(II) complexes of the designer structures showed significant in vitro hydrolytic and oxidative DNase activity and
