Retrieving Telemetry Range From ICESat-2 Data by a No-Prior-Terrain Onboard Filtering Algorithm

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) is widely used in mapping and monitoring the changes of ice sheets and forest vegetation. However, the satellite receives all the photons returning from around 532 nm, including surface signal ...

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management

Advanced Functional Materials, EarlyView.
A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...

Study on SMA driven hopper design for planetary exploration

Nihon Kikai Gakkai ronbunshu, 2018
This paper studies the feasibility of a hopper for planetary exploration rovers. The proposed hopper is designed based on shape memory alloy(SMA) actuators, because SMA actuators are light in mass compared with traditional electric motors.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

Advanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Dual‐Programmable Architected Magnetic Soft Materials: Tuning Mechano–Electric Responses by Inverse Design

Advanced Functional Materials, EarlyView.
ABSTRACT Materials that can deform, sense, and autonomously generate power in response to wireless magnetic fields, through both magnetic‐actuated shape transformation and charge generation, are an emerging focus in advanced functional materials research.
