New Battery Technology to Increase EV Range by 10 or More

Nanotechnology Article
With local sales hitting 108,000 units and global sales topping $1 trillion (approximate KRW 1,283 trillion) in 2022, the market for electric vehicles has been expanding rapidly. Clearly, there is a rising need for large-capacity batteries that can increase the range of electric vehicles. A functional polymeric binder for stability, a team of researchers from POSTECH and Sogang University recently created high-capacity anode material, and it has the potential to at least 10-fold enhance the current EV range. A research team led by POSTECH professors Soojin Park (Department of Chemistry) and Youn Soo Kim (Department of Materials Science and Engineering)

Nanoparticles Stimulate Immune Responses against Tumors while Avoiding Side Effects

Nanotechnology News
Nanoparticles have been extensively researched for their potential in cancer treatment, particularly for directly delivering therapeutic agents to tumors. Nanoparticles have the advantage of being able to be engineered to specifically target cancer cells while avoiding healthy cells, lowering the risk of side effects. Certain nanoparticles have also been shown in recent research to stimulate an immune response against tumors. This is due to the fact that nanoparticles can act as adjuvants. Researchers discovered that when immunostimulatory drugs known as imidazoquinolines are delivered using specialized bottlebrush nanoparticles, the drugs stimulate the immune system to attack tumors while avoiding the side

Maximizing extracellular vesicles: A new procedure for separation and measurement to improve patient care

Nanotechnology Article
It's a major forward-moving step in utilizing extracellular vesicles (EVs) as a demonstrative device. J. Nathaniel Diehl, Ph.D., the lead author of the study, led research at the UNC School of Medicine that demonstrated how a new method for handling extracellular vesicles can significantly enhance the diagnostic and therapeutic potential of disease development. Cell fragments break off and travel throughout the body as extracellular vesicles (EVs). The significance of their part in the body has come into more clear focus over the most recent couple of years, while already analysts had no clue in the event that these vesicles had

Nano-networks are created by self-integrating atomic quantum wires.

Nanotechnology Article
Quantum propellers depend on the creation of nanoscale wires that depend on a few cutting-edge nanolithographic innovations to foster wires by means of base-up union. However, creating network structures and uniform atomic crystalline wires for the construction of nanocircuits is a significant obstacle. A straightforward method for creating atomic-scale wires in the shapes of nano-rings, stripes, and X-Y junctions was discovered by Tomoya Asaba and a group of physicists and materials scientists from the Institute of Theoretical Physics in Germany, the University of Tokyo in Japan, and Kyoto University. The physicists and materials scientists grew single-crystalline, atomic-scale wires of a

Bond resonance hypothesis in flat boron materials is proposed by scientists.

Nanotechnology Article
Due to their similarity to graphene, two-dimensional (2D) boron sheets known as borophenes have recently piqued the interest of material scientists. Be that as it may, comprehension of how the material can be steady in the 2D structure is as yet missing, chiefly because of boron's extraordinary electron-lacking nature. In science, molecules in a steady material by and large submit to the octet rule. A carbon atom typically shares eight electrons with its neighbors through four chemical bonds, specifically 3 and 1 bonds for carbon atoms in graphene. While a boron molecule has just 3 valence electrons, its solidity, or

In a nanomagnetic array, magnetic energy strings bend, wriggle, and reattach.

Nanotechnology Article
A model nanomagnetic array, whose behavior can be best described as that of a collection of jiggling strings, has been developed and measured by a multi-institutional team investigating the physics of collective behavior. The lattice's strings are made up of connected, high-energy points that can expand and contract while also coming together. These strings are unique because they can only connect to certain endpoints and must do so in particular ways. Topological behavior, which physicists refer to as "constraints on the behavior of strings," is related to a wide range of topics, including the shape of a donut and the

Researchers have discovered severely compressed directional THz waves in thin semiconductor crystals.

Nanotechnology Article
THz waves that travel along thin anisotropic semiconductor platelets in the form of plasmon polaritons have been imaged and analyzed by a global team of researchers at wavelengths that are up to 65 times shorter than those of THz waves in free space. Even more fascinating is the fact that the wavelengths change in response to the propagation direction. These THz waves can be used to investigate fundamental nanometer-scale material properties and pave the way for the creation of ultra-compact on-chip THz devices. Nature Materials has published the work. The coupling of light and matter excitations results in the formation

Atomically precise design of graphene-based quantum circuits

Nanotechnology Article
Imagine having a structure made of heaps of blocks associated with versatile scaffolds. You pull a handle that adjusts the extensions, and the structure changes its usefulness. Wouldn't that be awesome? A group of scientists led by Prof. Aitor Mugarza, from the Catalan Organization of Nanoscience and Nanotechnology (ICN2) and ICREA, along with Prof. Diego Pea from the Middle for Exploration in Organic Science and Atomic Materials of the College of Santiago de Campostela (CiQUS-USC), Dr. Cesar Moreno, previously a colleague and presently a scientist at the College of Cantabria, and Dr. Aran Garcia-Lekue, from the Donostia Worldwide Physical Science

High-frequency light is generated via a new nanoparticle source.

Nanotechnology Article
Light with a high frequency is useful. The shorter the wavelength of light, the smaller the objects and details it can see—the higher the frequency, the shorter the wavelength. So violet light can show you more modest subtleties than red light, for instance, since it has a more limited frequency. However, to see minuscule things — down to the size of billionths of a meter, a great many times not exactly the width of a human hair — to see those things, you want outrageously bright light (and a decent magnifying instrument). With wavelengths ranging from 10 to 120 nanometers,

Light emission from black phosphorus research suggests new possibilities.

Nanotechnology Article
Numerous types of lighting, both indoors and outdoors, are beginning to be replaced by energy-efficient LEDs (light-emitting diodes). Materials research, which significantly improved the quality and intensity of light that can be achieved with these devices, has been a major contributor to the rise of LEDs. However, these materials need to be handled with extreme precision, including surfaces that are as free of imperfections as possible. Ali Javey, a senior faculty scientist at the Lawrence Berkeley National Laboratory (Berkeley Lab), said of the materials used in today's LED devices, "They're more efficient and last longer." However, "to get good efficiencies,
