The Advent of Nanomedicine

Image
  The advent of nanomedicine represents a significant step forward in healthcare. It offers novel approaches to the diagnosis and treatment of a wide range of diseases. Nanomedicines are already transforming healthcare, and new nanomedicines that emerge in the coming years will continue to transform future possibilities in the sector. The concept of leveraging nanoparticles in medicine originated in the 1960s, although it was not until the 1990s that significant progress in this field began, thanks to the advent of nanotechnology. Nanomedicine has already helped develop improved drug delivery systems that enhance therapeutic impact while minimizing side effects. Nanotechnology has also been leveraged in designing and developing novel diagnostic platforms that are more sensitive than traditional approaches and allow for more accurate disease monitoring. The emergence of nanomedicines has helped advance targeted therapies, theranostics, personalized medicine, imaging, and cancer trea...

Plasma treatment enhances electrode material for fuel cells in industry, homes and vehicles

Image
  Researchers from Skoltech and their colleagues have improved the properties of a carbon-based electrode material by exposing it to air plasma. Such treatment turned out to enhance electrode performance, which is the limiting factor for high-tech energy sources—particularly fuel cells. These are a promising technology for cleaner and more efficient electrical power generation. Published in the Journal of Electroanalytical Chemistry, the study even shows that the cheaper-to-make air plasma is better-suited for processing the carbon material than pure nitrogen or oxygen plasma. One way to make burning natural gas cleaner is to use fuel cells. These are devices that technically do not burn the fuel but rather oxidize it in a different manner. That process is friendlier to the environment, because it produces more useful power, less greenhouse gases and emits no pollutants such as nitrogen oxides, sulfur dioxide, and aerosol particles. Fuel cells are used to power industrial facilitie...

  Tribology is the study of interacting surfaces in motion and the measurement of properties such as friction, wear and abrasion. When designing nanoscale devices the consideration of tribology is particularly important because the high surface area ratio enhances problems with friction and wear. Understanding nanoscale surface changes of tribological properties will also allow for either increased or decreased friction at a greater scale than currently provided by macroscopic lubrication and adhesion. Scanning probe microscopy techniques such as the atomic force microscope are being utilized to assess tribological properties at the nanoscale. The tip of the atomic force microscope provides contact with a solid or lubricated surface in order to study properties such as adhesion, friction and wear. The information provided can be used to further the understanding of nanotribology and predict how this affects nanomaterial surface interactions. Current nanotechnology applications of ...

Nanotechnology promises improved energy storage, solar conversion

  The emergent field of nanotechnology offers “extraordinary possibilities in the area of sustainable energy, providing innovative solutions for improving green energy,” says the World Nano Foundation. The Foundation is a globally recognised not-for-profit membership organisation at the forefront of nanoscale technology advancement. Its recently released white paper, Unleashing the Potential of Nanotechnology for Superior Energy Storage and Solar Conversion Solutions delves into the possibilities of nanotechnology in reshaping energy storage and solar conversion. The Foundation said this field offers “innovative solutions to drive sustainable energy practices.” The white paper investigates the most recent breakthroughs in nanotechnology that pave the way for more effective and efficient energy storage and solar conversion. “The global challenge of transitioning from fossil fuels to sustainable energy sources necessitates advanced technology, and nanotechnology offers a promising so...

'Stunning' discovery: Metals can heal themselves

Image
Scientists for the first time have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process. If the newly discovered phenomenon can be harnessed, it could usher in an engineering revolution—one in which self-healing engines, bridges and airplanes could reverse damage caused by wear and tear, making them safer and longer-lasting. The research team from Sandia National Laboratories and Texas A&M University described their findings today in the journal Nature. "This was absolutely stunning to watch first-hand," said Sandia materials scientist Brad Boyce. "What we have confirmed is that metals have their own intrinsic, natural ability to heal themselves, at least in the case of fatigue damage at the nanoscale," Boyce said. Fatigue damage is one way machines wear out and eventually break. Repeated stress or motion causes microscopic cracks to form. Over time, these cracks grow ...

Plasmonics

Plasmonics A plasmon is defined as a quantum oscillation of the free electron cloud with respect to the fixed positive ions in a metal and those that are confined on surfaces and strongly interacting with light are called surface plasmons.
