Electrostatic Dust Analyzer for Dust Transport Measurements on the Lunar Surface

open access: yesThe Planetary Science Journal
Lunar dust charging and transport is a more than five-decade-old problem. A high-fidelity and flight-qualified Electrostatic Dust Analyzer (EDA) has been developed to measure the charge, velocity, mass (size), and flux of electrostatically lofted dust ...

Moisture‐Adaptive Triboelectric Materials and Platforms: Design Strategies, Performance Enhancement, and Applications in Energy Harvesting and Wearable Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
This review summarizes moisture‐adaptive strategies that enable triboelectric nanogenerators (TENGs) to operate across diverse moisture conditions. It examines moisture‐management methods, including exclusion, directional transport, removal, and utilization, with charge‐regulation approaches based on interfacial, dielectric, and structural engineering.

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

open access: yesAdvanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

Vertical Gate‐All‐Around SiGeSn/GeSn/SiGeSn Nanowire Transistors for Energy‐Efficient Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
Band‐engineered SiGeSn/GeSn/SiGeSn heterostructures enable complementary vertical nanowire MOSFETs and steep slope tunnel FETs (TFETs) within a unified Group‐IV platform. Leakage suppression and tunnelling‐path engineering demonstrate an effective strategy for future low‐power and energy‐efficient integrated electronics.

Dusty space plasma diagnosis using temporal behavior of polar mesospheric summer echoes during active modification [PDF]

open access: yes, 2011
The objective of this paper is to study the effect of different plasma and dust parameters on Polar Mesospheric Summer Echoes (PMSE) temporal behavior after turn-on and turn-off of radio wave heating and to use these responses to diagnose the properties ...

Self‐Sealing Microneedles Improve Precision and Reduce Reflux in Subretinal Cell Transplantation

open access: yesAdvanced Materials Technologies, EarlyView.
Ultrafine 49G microneedles enable subretinal delivery of induced pluripotent stem cell‐derived retinal pigment epithelial cells through a 50 µm outer diameter tip. Compared with conventional 38G microcannulas, these microneedles reduce cell suspension reflux in a rabbit model, highlighting the potential of microinvasive delivery instruments to improve ...

Dust-induced instability in a rotating plasma

open access: yes, 2008
The effect of immobile dust on stability of a magnetized rotating plasma is analyzed. In the presence of dust, a term containing an electric field appears in the one-fluid equation of plasma motion.

Nonthermal effects on the resonant instability of the dust-acoustic wave in a semi-bounded Lorentzian dusty plasma

open access: yes, 2011
The nonthermal effects on the resonant instability of the surface dust-acoustic wave are investigated in a semi-bounded Lorentzian dusty plasma containing elongated rotating dust grains. It is found that the nonthermal effects reduce the frequency domain
