Morphogenic Growth 3D Printing

Advanced Materials, EarlyView.
I additive manufacturing process exploits the spatial propagation of a polymerization reaction front to produce 3D polymer parts 10× faster and 1000× more energy efficient than the fastest stereolithography. In contrast with existing 3D printing, this morphogenic process is inspired by biological “growth and form” due to the self‐directed propagation ...

A Quantitative Scaling Theory for Meridional Heat Transport in Planetary Atmospheres and Oceans

AGU Advances, 2021
The meridional temperature profile of the upper layers of planetary atmospheres is set through a balance between differential radiative heating by a nearby star, or by intrinsic heat fluxes emanating from the deep interior, and the redistribution of that

The Interplay of Surface Composition, Mineralogy, and Physical Conditions That Affect the Surface Release Processes and Particle Environment of Mercury

The Planetary Science Journal
Mercury has a very tenuous atmosphere starting at the surface, which is referred to as a surface-bound exosphere, where there are no collisions between exospheric particles.

Planetary Core Formation with Collisional Fragmentation and Atmosphere to Form Gas Giant Planets

, 2011
Massive planetary cores ($\sim 10$ Earth masses) trigger rapid gas accretion to form gas giant planets \rev{such as} Jupiter and Saturn. We investigate the core growth and the possibilities for cores to reach such a critical core mass. At the late stage,
