MXene 3D‐AJP: Three‐Dimensional Well‐Oriented Freeform Networks of 2D MXene Nanosheets via Aerosol‐Based 3D Printing

Small, EarlyView.
This study presents an additive‐free aerosol jet 3D printing technique for assembling 2D MXene nanosheets into complex, customizable, high‐aspect‐ratio 3D microarchitectures without binders. By leveraging real‐time ink thickening, the authors also fabricate 3D microsupercapacitors with interdigitated electrodes that holds breakthrough device areal ...

Nanoscale Ripples at the Surface of SrTiO3 Irradiated by a Broad Low‐Energy Ar+ (7 keV) Ion Beam

Small, EarlyView.
Broad Ar ion beam irradiation creates self‐organized ripple nanostructures on oxide surfaces. A schematic illustrates the process, while cross‐sectional STEM imaging captures the ripple morphology. Complementary elemental mapping by EELS highlights nanoscale chemical variations, linking ion‐beam nanostructuring with structural and compositional ...

Additive‐Free Edge‐Functionalized Graphene Dough

Small, EarlyView.
An edge‐functionalized, few‐layer graphene dough, synthesised directly from graphite, provides an additive‐free, processable graphene for moldable and printed electronic and magnetic applications. ABSTRACT The exploitation of graphene's extraordinary properties depends on finding new ways to synthesize and process it without disrupting its fundamental ...

Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene

Small, EarlyView.
Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

Single‐Particle Insights Into the Electronic Structure and Enhanced Stability of CsPbBr3/FAPbBr3 Core/Crown Nanoplatelets at the Nanometer Scale

Small, EarlyView.
Single‐particle‐level investigation using scanning tunneling spectroscopy reveals electronic structure and type‐I band alignment of individual CsPbBr3@FAPbBr3 core‐crown nanoplatelet. Crown passivation suppresses deep trap states by 47% and markedly improves electrical stability under repeated bias sweeps.

SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications

Small, EarlyView.
This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.
