Focus: New Spaceship Sail Self-Facilities

December 13, 2019• Physics 12, 143 A know-how for propelling spacecraft utilizing a “sail” pushed by gentle has handed an preliminary check, with the prototype system staying centered in a laser beam. M. Martin/Rochester Inst. of Tech. Fly by gentle. A lightweight sail utilizing diffractive gratings, as depicted on this artist’s conception, generates sideways forces that might preserve it aligned with a laser beam or permit it to be steered in direction of a goal.…

Surprise Materials Grows on Bushes

December 12, 2019• Physics 12, 142 A fabric that mixes graphite with cellulose from wooden pulp is lighter and stronger than structural supplies like steels, titanium alloys, and carbon fibers. A graphite-cellulose composite with a “brick-and-mortar” construction is stronger than metal. Nanocellulose fibers (in inexperienced) function the “mortar” that holds collectively the “bricks,” that are 100-𝜇m-sized graphite flakes (in grey). A graphite-cellulose composite with a “brick-and-mortar” construction is stronger than metal. Nanocellulose fibers (in inexperienced)…
