After that, we mold the carrier and fragile functional materials into whatever particles we want and gently wash them off the molds with buffer solutions into vials or other containers to concentrate them.

Climatologists discover deep-sea secret

...t global warming could cause part of the Greenland ice sheet to melt, giving rise to increased levels of freshwater in the Atlantic Ocean. This could reduce the strength of the gulf stream, creating a cooler, dryer climate in Europe and North America. However, according to the authors of this latest stu...

NASA probe could reveal comet life, scientists claim

...omerate of ices, but a porous mass of organics and ice under the black asphalt crust." Comets are thought to have accumulated from a mixture of ices and organic interstellar dust at the time the solar system was formed some 4.6 billion years ago. "This material is quite porous, so it is daring again to...
