Uniaxial Stress Enhanced Anisotropic Magnetoresistance and Superconductivity in the Kagome Superconductor LaRu3Si2

open access: yesAdvanced Materials, EarlyView.
We identify strong anisotropy in the upper critical field and magnetoresistance in the kagome superconductor LaRu3Si2, revealing pronounced electronic anisotropy. Uniaxial stress enhances magnetoresistance and Tc, with a positive correlation suggesting an electronic pairing mechanism.

Aloe vera gel mediated green synthesis of ruthenium nanoparticles and their potential anticancer activity

open access: yesNext Nanotechnology
Metal nanoparticles have a noteworthy future in cancer treatment research because of their smaller size and large active surface area. Though gold, silver, platinum, palladium, copper, zinc, iron and several other metal nanoparticles have been explored ...

Ruthenium and Osmium Metalloradicals [PDF]

open access: yesAngewandte Chemie International Edition, 2010
Radical design: Unprecedented stability of ruthenium(I) and osmium(I) complexes with metalloradical character has been achieved by use of judiciously chosen supporting ligands based on the tris(o‐phosphinophenyl)silyl motif. The pronounced radical character on the ruthenium(I) center is also enforced by non‐innocent ligands of the diiminopyridine type.

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

Hydrodeoxygenation of lignin-derived guaiacol using ruthenium‑titanium-oxide aerogel catalysts

open access: yesApplied Catalysis O: Open
Catalytic hydrodeoxygenation of biomass-derived oxygenates to deoxygenated chemicals and fuels is a major research area, but selective production of aromatic compounds remains challenging, because complete deoxygenation favors formation of saturated ...

Operando X‐Ray Absorption Spectroscopy Reveals Dynamic Interfacial Metal–Metal Coordination Governing CO2 Reduction Selectivity in PdAg Alloys

open access: yesAdvanced Materials Interfaces, EarlyView.
Operando X‐ray absorption spectroscopy uncovers dynamic Ag–Pd coordination in PdxAg1−x electrocatalysts during CO2 reduction. Partial oxidation of Ag and composition‐dependent metal–metal bonding synergistically regulate intermediate binding, enabling ∼91% CO selectivity.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

open access: yesAdvanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.
