Jun 16, 2023 (Nanowerk News) Controlling chemical reactions to generate new products is one of the biggest challenges in chemistry. Developments in this area impact industry, for example, by reducing the waste generated in the manufacture of construction materials or by improving the production of catalysts to accelerate chemical reactions....
Novel approach to fabricating artificial graphene nanoribbons with embedded pentagon carbon
Jun 16, 2023 (Nanowerk News) Graphene nanoribbons (GNRs) have attracted much attention due to their unique electronic structures with high tunability of physical structures. However, the fabrication feasibility of artificially tuned GNRs intrinsically associated with their external properties brings considerable challenges in the synthesis of GNRs and their utilization in...
The unique properites of metal nanoclusters for applications from catalysis to biomedicine
Jun 16, 2023 (Nanowerk News) In a recent comprehensive review article in Nature Reviews Materials ("Understanding ligand-protected noble metal nanoclusters at work"), researchers from the Nanoscience Center at the University of Jyväskylä, Finland, discuss the unique properties of nanometer-size metal clusters that make them suitable for various applications in catalysis,...
Nanopores can contribute to faster identification of diseases
Jun 16, 2023 (Nanowerk News) In a collaboration with Groningen University, Professor Jørgen Kjems and his research group at Aarhus University have achieved a remarkable breakthrough in developing tiny nano-sized pores that can contribute to better possibilities for, among other things, detecting diseases at an earlier stage. Their work, recently...
To boost supply chains, scientists are looking at ways to recover valuable materials from water
Jun 16, 2023 (Nanowerk News) For many materials critical to supply chains that will help enable America’s decarbonization transition, resources are limited. Traditional mining is fraught with challenges, so advancing clean energy depends on finding new ways to reliably access critical materials. Promoting national security and economic competitiveness will...
Revolutionary new method can manipulate the shape and packing of DNA
Jun 16, 2023 (Nanowerk News) A human cell harbors roughly 2 meters of DNA, encompassing the essential genetic information of an individual. If one were to unwind and stretch out all the DNA contained within a single person, it would span a staggering distance – enough to reach the sun...
When materials discovery glitters
Jun 15, 2023 (Nanowerk News) Thomas Edison famously tried hundreds of materials and failed thousands of times before discovering that carbonized cotton thread burned long and bright in an incandescent light bulb. Experiments are often time consuming (Edison’s team spent 14 months) and expensive (the winning combination cost about $850,000...
Discovery of white dwarf pulsar sheds light on stellar evolution
Jun 15, 2023 (Nanowerk News) White dwarfs are extremely dense stellar remnants with the mass of our Sun but the small size of our planet Earth. They are formed when a low-mass star has burned up all its fuel, loses its outer layers and its interior contracts strongly. They are...
