Nickel Intercalation in Epitaxial Graphene on SiC(0001): A Novel Platform for Engineering Two‐Dimensional Heterostructures

Advanced Science, EarlyView.
Ni‐intercalated graphene on SiC is achieved through a scalable colloidal nanoparticle deposition route. 2D heterostructures show preserved graphene band structure, stable under ambient conditions, and robust interfacial magnetism. Intercalated 2D Ni represents a promising candidate for next‐generation spintronic devices and is a scalable pathway to ...

Pressure‐Tuned Superconducting Dome and Persistent Charge‐Density‐Wave Order in NdSeTe2

Advanced Science, EarlyView.
NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

Engineering Borophene Band Structure Through Thickness

Advanced Science, EarlyView.
Borophene grown on W(110) shows a thickness‐dependent evolution of its structural and electronic properties. Surface microscopy, diffraction, XPS, and ARPES reveal distinct monolayer and bilayer phases. The formation of the second layer is accompanied by structural reconstruction, changes in chemical properties, and new ARPES features, demonstrating ...

Smartphone‐Guided Visible Light Modulation of RSNOs for Antimicrobial Activity via Controlled Nitric Oxide Release

Advanced Science, EarlyView.
A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...
