Study on the Influence of Rigid Wheel Surface Structure on the Trafficability of Planetary Rover on Soft Ground

open access: yesAerospace
In order to explore the influence of wheel surface structure on the trafficability of planetary rovers on soft ground, three kinds of wheels with different rigid wheel surface structures were selected for research. The basic performance parameters of the

Shaping Carbon Nitrides for Advanced Macrostructures

open access: yesAdvanced Materials Technologies, EarlyView.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

Low-ionization structures in planetary nebulae

open access: yes, 1999
We present new results of a program aimed at studying the physical properties, origin and evolution of those phenomena which go under the somewhat generic definition of "low-ionization, small-scale structures in PNe". We have obtained morphological and kinematical data for 10 PNe, finding low-ionization structures with very different properties ...

Wet Ball Milling Synthesis of Iron Oxide Nanoparticles for High‐Efficiency, Controllable Magnetic Hyperthermia in Ovarian Cancer

open access: yesAdvanced Materials Technologies, EarlyView.
A wet ball‐milling method is presented to synthesize iron magnetic nanoparticles and evaluate their magnetic hyperthermia performance. Optimized particles (∼270 nm, Ms ∼114 emu/g) achieve ∼50°C heating under clinically safe alternating magnetic fields, while pulsed‐field operation enables controlled temperature regulation (∼30°C).

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
