Enhancing the Chemical Reactivity of Graphene through Substrate Engineering

Small, EarlyView.
This review highlights methods to enhance the reactivity of graphene through substrate engineering, focusing on strain and charge doping. Strains induced by nanoparticles, metal crystal orientations, or stretchable polymers increase the reactivity of graphene.

160 GHz Schottky Diodes from Solution‐Processed IGZO

Small, EarlyView.
A simple, scalable method for contact engineering of planar asymmetric nanogap electrodes enables the development of Schottky diodes with a cut‐off frequency of 160 GHz. Applying these diodes to radio‐frequency rectifying circuits yields output voltages in the range of 0.3–0.74 volts.

Unravelling Electronic Structure and Molecular Vibrations of Proteins in Virus Using Novel Correlated Plasmon‐Enhanced Raman Spectroscopy With Machine Learning

Small, EarlyView.
A novel, non‐destructive, stable, direct technique, named correlated plasmon‐enhanced Raman spectroscopy (CP‐ERS), which is based on a newly‐developed highly oriented single crystalline gold quantum dots (HOSG‐QDs) chip, is developed to measure and quantify molecular vibrations and electronic structure of analytes.

Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

Small, EarlyView.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Ultrathin Freestanding MoSiN Nanocomposite Membranes as Efficient High‐Temperature Mid‐Infrared Thermal Emitters

Small, EarlyView.
Ultrathin freestanding MoSiN nanocomposite membranes are developed as stable and efficient mid‐infrared emitters for gas sensing under extreme thermal conditions. A 12 nm‐thick membrane combines intermetallic phases for enhanced IR absorption with a dielectric phase for mechanical stability.

Guiding the Formation of Surface‐Confined 2D Metal–Organic Coordination Networks by Variation of Constituent Landing Energy in Electrospray Deposition of an Iron(II) Grid Complex

Small Methods, EarlyView.
Electrospray ion beam deposition (ES‐IBD) of an Fe(II) [2 × 2] grid complex onto Ag(111) reveals landing energy‐dependent fragmentation and self‐assembly. At higher landing energies, novel coordination networks emerge. This study highlights the unique potential of ES‐IBD in creating diverse metal–organic architectures on surfaces.
