Flat tip tweezers, pictured at right, have an angled tip which may be used for removing splinters. Some tweezers have a long needle-like tip which ...
By patterning the surface with gold microscopic islands it is possible to have selective and parallel trapping in these islands. The forces of the latter optical tweezers lie in the femtonewton range. [72] The evanescent field can also be used to trap cold atoms and molecules near the surface of an optical waveguide or optical nanofiber. [73] [74]
YouTube has also presented advocacy campaigns through special playlists featured on YouTube Kids, including "#ReadAlong" (a series of videos, primarily featuring kinetic typography) to promote literacy, [12] "#TodayILearned" (which featured a playlist of STEM-oriented programs and videos), [13] and "Make it Healthy, Make it Fun" (a ...

In the 1950’s, the birth of the electronic industry spurred the need for a material that had less magnetism. Precision tweezers began popping up made of AISI 303/304 and AISI 316 Stainless Steel.
