Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
An international team of astronomers observed these remarkable objects with the Atacama Large Millimeter/submillimeter Array (ALMA).
When the double asteroid Patroclus-Menoetius passed directly in front of a star on the night of Oct. 20, a team of volunteer astronomers across the U.S. was…
Nanocrystalline Cellulose (NCC) is a green and renewable material that has recently gained huge interests. Due to its interesting properties it has a wide possible application range and can be used as reinforcement material in the construction industry as well as in drug delivery systems and as material for implants. However, at the moment its complicated and expensive manufacturing process represents a significant obstacle to a widespread application of NCC. The present invention is characterized by a neutralization step terminating the acidic hydrolysis of the cellulose fibers during the production procedure. This uncomplicated, but very effective further step enables an ?easy-made-separation? of the NCC by centrifugation. Therefore, this innovative technology will pave the way for a wide range of applications of this fascinating new material.
