Recently, a research team at the Charles Sutton Institute of the National Academy of Sciences in France assembled thousands of nanomachines to produce a coordinated contraction and relaxation movement like muscle fibers with an extension of about 10 microns. Related papers are published on the Applied Chemistry website.
In the past few years, synthetic chemists have made dazzling progress in the field of artificial nanomachines. More and more research has begun to turn to their mechanical properties, but how can we make many nanomachines coordinate in time and space yet? solve.
Now, the research team led by Professor Nicholas Giuseppeni of the University of Strasbourg, France, has successfully synthesized a long polymer chain that combines thousands of nanomachines through supramolecular bonds. Nanomachines can produce linear stretching motions of about 1 nanometer. Under the influence of pH, their simulated motion can cause 10 micron contraction or relaxation of the entire polymer chain, so the various movements are correspondingly magnified 10,000 times, just like in muscle tissue.
The researchers point out that this result will open up broad prospects for many applications, such as micro- robots , nano-information storage, synthetic muscles, etc. These assembleable nanomachines can also be used to design other materials with novel mechanical properties.
This product is a currently popular flexible retractable multi-functional solar energy charger, the main functions are: solar energy charging storage system, mobile power, SOS signal and flashlight functions. It USES a high-performance lithium battery as a storage battery to charge the phone while receiving sunlight, and can use a strong flashlight at the same time. The product itself can be directly charged by the charging power adapter, or can be charged through the solar energy charging plate, which is very convenient to use. It is a good choice for your friends who love outdoor sports to solve the problem that the device does not have electricity at any time and place.
The FIZZ GLOBAL has developed one of the most compact solar energy rechargeables on the market. It is very portable, and its solar panels can be folded like an old-fashioned camera roll.
FIZZ GLOBAL said it hoped the product would reduce carbon emissions during charging and that people would focus on clean energy.
