“We found that the valve-based printing is gentle enough to maintain high stem cell viability, accurate enough to produce spheroids of uniform size, and most importantly, the printed hESCs maintained their pluripotency - the ability to differentiate into any other cell type."
A combination of laser parameters resulting in a 2.12 J/mm2 laser energy appeared to be ideal for generating a melt pool necessary for lunar regolith powder deposition without excessive liquid pool spreading and cracking of solidified parts. The results show that LENS™ based laser processing transformed crystalline regolith into nanocrystalline and/or amorphous regolith structures as a result of complete melting followed by resolidification. Laser processing also resulted in marginal changes in the composition of the regolith.
Metamaterials are, by their very definition, awesome. The first sentence of the Metamaterials entry on Wikipedia reads:
Metamaterials are artificial materials engineered to have properties that may not be found in nature.
And as should be expected of materials that are supernatural, they can endow objects with properties that seem uncanny. In recent years, researchers have used metamaterials to create “invisibility cloaks” and “super lenses” capable of focusing light to such a degree that objects on the nanoscale can be imaged.
