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.

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.

High‐Power Performance of Textured Piezoelectric Ceramics Through Synergistic A‐Site Donor and B‐Site Acceptor Doping

Small Methods, EarlyView.
A/B‐site co‐doping combined with templated grain growth enables synergistic defect and domain engineering in textured PIN–PMN–PT ceramics. The approach simultaneously enhances piezoelectric response and mechanical quality factor, achieving a balanced soft–hard characteristic.

Shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
For adaptive X‐ray optics on high‐performance beamline optical systems, we describe an approach to mirror figure and slope control using patterned, shaped electrodes to control the local curvature on a lithium niobate substrate from a single applied voltage. Longitudinally continuous electrode patterns achieve target shapes without discontinuities, and

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.

Spin Defects in Hexagonal Boron Nitride as 2D Strain Sensors

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
We demonstrate that boron‐vacancy (VB${\rm V}_{\rm B}$) centers in hexagonal boron nitride (hBN) enable quantitative strain sensing with sub‐micrometer resolution. Using this approach under continuously tunable in‐plane stress, we precisely quantify strain‐induced shifts of the E2g${\rm E}_{2{\rm g}}$ Raman mode in multilayer hBN, establishing VB${\rm ...
