MODULAR IMPULSIVE GREEN MONOPROPELLANT PROPULSION SYSTEM (MIMPS-G): SYSTEM ANALYSIS AND PRELIMINARY DESIGN

open access: yes, 2021
Propulsion systems for small-sized spacecraft are trending toward miniaturization and system modularity. Moreover, green propulsion is becoming the norm in space propulsion, particularly in CubeSats, due to the high performance and favorable physi ...

Molecularly Dissipative Liquid Crystal Elastomer Foams for Impact and Vibration Attenuation

open access: yesAdvanced Functional Materials, EarlyView.
Liquid crystal elastomer foams integrate cellular deformation with mesogen reorientation to create a dual‐scale energy dissipation mechanism. Progressive pore collapse absorbs mechanical loads, while stress‐induced mesogen reorientation provides additional damping, resulting in reduced impact transmission and broadband suppression of vibrational ...

Extension of Martian orbits using continuous low-thrust propulsion [PDF]

open access: yes, 2012
There has recently been significant interest in exploration of the Martian surface and atmosphere with a view to future human exploration. Thus missions must be developed which are responsive to these scientific goals.

Magneto‐Ionic Devices With Polymer‐Based Electrolytes

open access: yesAdvanced Functional Materials, EarlyView.
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Unexpected Asymmetric Mn‐Sb Site Mixing and Reentrant Spin‐Glass State of MnSb2Te4

open access: yesAdvanced Functional Materials, EarlyView.
MnSb2Te4 is an intrinsic magnetic topological insulator. Its properties are extraordinarily sensitive to tiny defects, making structural studies essential for understanding how magnetism and topology work together. This work shows that Mn can be unevenly distributed within the crystal and how that disorder is linked to a newly reported spin‐glass state

Remote Activation of Wnt Signaling and Cell Proliferation by E‐Cadherin Magnetomechanical Stimulation

open access: yesAdvanced Functional Materials, EarlyView.
A pioneering magnetogenetic toolkit enables non‐invasive, precise spatiotemporal modulation of intracellular Wnt/β‐catenin signaling. Functionalized magnetic nanoparticles (MNPs@E/EC15) target cellular E‐cadherins to generate localized magnetomechanical forces under low‐intensity magnetic fields.
