Nanotechnology is one of the important new technologies in the 21st century. Nanotechnology is an applied science that aims to study the design methods, composition, properties, and applications of matter and devices at the nanoscale. The magic of nanotechnology lies in the quantum and surface phenomena that matter possesses at the nanoscale, which allows many important applications and interesting materials to be made.
In this article, InnovationForever aims to introduce you to some recent new developments in nanomaterials science around the world for your paper.
1 Fluorine-containing nanostructures for desalination of seawater
Desalination is one way to produce drinking water, but it often comes with significant energy costs. In May of this year, Japanese researchers successfully filtered salt from water for the first time using fluorine-based nanostructures. Compared to the main current desalination methods (thermal and reverse osmosis membrane methods), the fluorine ion nanochannels work faster, require less pressure and energy, and are more efficient filters.
Fluorine is a naturally water-repellent or hydrophobic lightweight element. Fluorine is electronegative and it repels negative ions, such as chlorine in salt. This has the advantage of breaking up the water molecule groups (water clusters) that are essentially loosely bound, so they can pass through the channel faster. The team's fluorine-based water desalination membrane is more efficient, faster, requires less energy to operate, and is very easy to use.
2 Improving lithium battery performance
To improve electrical performance in extreme cold conditions, researchers at the American Chemical Society (ACS) announced that they have replaced conventional graphite anodes in lithium-ion batteries with a dimpled carbon-based material that can maintain its rechargeable storage capacity at -35°C.
The researchers heated the cobalt-containing zeolite imidazolium ester structured material (ZIF-67) at high temperatures. The resulting 12-sided carbon nanospheres have a bumpy surface and exhibit excellent charge transfer capabilities. By incorporating the uneven nanosphere material into lithium-ion batteries, the researchers say, these batteries will have the potential to be applied at very low temperatures.
3 Möbius carbon nanoribbons
Building structurally homogeneous carbon nanoribbons is critical to the development of functional materials for nanotechnology, electronics, optics and biomedical applications. It was recently reported that a team of researchers at Nagoya University in Japan has synthesized a ribbon-like molecular nanocarbon with a distorted Möbius band topology, known as Möbius carbon nanoribbons.
Researchers show that new forms of carbon and nanocarbon continue to open the door to new technologies and lead to the discovery of unpredictable and extraordinary properties, functions and applications. This work paves the way for the development of carbon nanomaterials with complex topologies and the birth of innovative materials science using Möbius topology.
4 Intelligent temperature-controlled nanotextiles
Researchers at Yunnan University in China recently developed a washable, breathable, and flexible wearable fabric that combines outdoor human temperature regulation, coded message transmission, and self-powered sensing.
The team recently developed a polyacrylonitrile bionic nanofabric (hereinafter referred to as nanofabric) that blends carbon black nanoparticles with barium titanate nanoparticles and has temperature-regulating functions.
By modulating the structural and optical properties of nanomaterials, this nanofabric possesses the function of outdoor human thermal management. This research result demonstrates the potential of cross-application of nanomaterials and material science and technology in the future.
