Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

When does category spanning hurt or help producers?

Strategic Management Journal, EarlyView.
Abstract Research Summary Scholars have theorized many factors shaping whether category spanning helps or hurts producers. We first synthesize evidence by meta‐analyzing 25 years of empirical research, which reveals a null effect of spanning on average, yet with significant subsample heterogeneity. To unpack it, we theorize and find that spanning hurts

Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

Small, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

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 ...

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.

COMPUTATIONAL BALLISTIC IMPACT ANALYSIS OF AIRCRAFT ARMORS

Havacılık ve Uzay Teknolojileri Dergisi, 2017
Lightweight and ballistic resistance are significant parameters in the design of aircraft armors. Aircraft should not compromise the payload or its maneuverability due to the armors added to the system.

Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...
