Mar 15, 2024 (Nanowerk News) The current theoretical model for the composition of the universe is that it’s made of ‘normal matter,’ ‘dark energy’ and ‘dark matter.’ A new uOttawa study challenges this. A University of Ottawa study (The Astrophysical Journal, "Testing CCC+TL Cosmology with Observed Baryon Acoustic Oscillation Features")...
Scientists develop a new system to record 2D crystal synthesis in real time
Mar 15, 2024 (Nanowerk News) Two-dimensional materials such as graphene and molybdenum disulfide (MoS2) exhibit unique properties that hold immense promise for applications in electronics, sensors, energy storage, biomedicine and more. However, their complex growth mechanisms — inconsistent correlations exist between how the conditions for growth affect the shapes of...
Speaking without vocal cords, thanks to a new AI-assisted wearable device
Mar 15, 2024 (Nanowerk News) People with voice disorders, including those with pathological vocal cord conditions or who are recovering from laryngeal cancer surgeries, can often find it difficult or impossible to speak. That may soon change. A team of UCLA engineers has invented a soft, thin, stretchy device measuring...
Comprehensive model predicts complex dynamics in free-radical photopolymerization
Mar 15, 2024 (Nanowerk Spotlight) The ability to rapidly transform liquid monomers into solid polymers using light has been a transformative technology for over half a century. This process, known as photopolymerization, enables the fast fabrication of coatings, adhesives, dental fillings, and intricate 3D printed structures on demand. In photopolymerization,...
Printed polymer allows researchers to explore chirality and spin interactions at room temperature
Mar 15, 2024 (Nanowerk News) A printable organic polymer that assembles into chiral structures when printed has enabled researchers to reliably measure the amount of charge produced in spin-to-charge conversion within a spintronic material at room temperature. The polymer’s tunable qualities and versatility make it desirable not only for less...
DNA origami-based vaccines toward safe and highly-effective precision cancer immunotherapy
Mar 15, 2024 (Nanowerk News) Therapeutic cancer vaccines are a form of immunotherapy in the making that could not only destroy cancer cells in patients, but keep a cancer from coming back and spreading. Multiple therapeutic cancer vaccines are being studied in clinical trials, but despite their promise, they are...
A new world of 2D material is opening up
Mar 15, 2024 (Nanowerk News) Since the discovery of graphene, the field of research in extremely thin materials, so-called 2D materials, has increased exponentially. The reason is that 2D materials have a large surface area in relation to their volume or weight. This gives rise to a range of physical...
