Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1

Small, EarlyView.
A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

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.
