Superflimsy graphene turned ultrastiff by optical forging
Stiffened graphene opens up avenues for novel applications
28-May-2021
Graphene is an ultrathin material characterized by its ultrasmall bending modulus, superflimsiness. Now the researchers at the Nanoscience Center of the University of Jyväskylä have demonstrated how an experimental technique called optical forging can make graphene ultrastiff, increase its ...
Researchers analyzed circulating currents inside gold nanoparticles
A new method facilitates accurate analysis of magnetic field effects inside complex nanostructures
04-May-2021
Researchers in the Nanoscience Center of University of Jyvaskyla, in Finland and in the Guadalajara University in Mexico developed a method that allows for simulation and visualization of magnetic-field-induced electron currents inside gold nanoparticles. The method facilitates accurate analysis ...
Choosing the right partner: Synthesis of a rare metal complex of nitrous oxide opens new vistas for the degradation of a potent greenhouse gas
25-Feb-2021
Like its chemical relative carbon dioxide (CO2), nitrous oxide (N2O) is an important greenhouse gas and the dominant ozone-depleting substance emitted in the 21st Century. Consequently, strategies for limiting its emissions and its catalytic decomposition with metals are being developed. A recent ...
Pancake bonding as a new tool to construct novel metal based magnetic materials
Study paves the way for new design strategy for novel multinuclear single-molecule magnets
17-Aug-2020
A Canadian-Finnish collaboration has led to the discovery of a novel magnetic compound in which two magnetic dysprosium metal ions are bridged by two aromatic organic radicals forming a pancake bond. The results of this study can be utilized to improve the magnetic properties of similar ...
Support drives fate of protected gold nanoclusters as catalysts
The choice of a support material may have drastic effects on the structure of the catalyst
17-Jun-2020
In collaboration with experimentalists from Ghent University, Belgium and Utrecht University, Netherlands, researchers at the Nanoscience Center (NSC) at the University of Jyväskylä, have recently discovered that the choice of a support material for model catalysts, made from gold nanoclusters ...
Researchers have discovered how a nanocatalyst works at the atomic level
31-May-2019
The researchers of the Nanoscience Center (NSC) at the University of Jyväskylä, Finland, and in the Xiamen University, China, have discovered how copper particles at the nanometre scale operate in modifying a carbon-oxygen bond when ketone molecules turn into alcohol molecules. Modification of ...
High-resolution imaging of nanoparticle surface structures is now possible
06-Aug-2018
Using scanning tunnelling microscopy (STM), extremely high resolution imaging of the molecule-covered surface structures of silver nanoparticles is possible, even down to the recognition of individual parts of the molecules protecting the surface. This was the finding of joint research between ...
Graphene forged into three-dimensional shapes
28-Sep-2017
Researchers from Finland and Taiwan have discovered how graphene, a single-atom-thin layer of carbon, can be forged into three-dimensional objects by using laser light. A striking illustration was provided when the researchers fabricated a pyramid with a height of 60 nm, which is about 200 times ...
Researchers develop DNA-based single-electron electronic devices
18-Oct-2016
Nature has inspired generations of people, offering a plethora of different materials for innovations. One such material is the molecule of the heritage, or DNA, thanks to its unique self-assembling properties. Researchers at the Nanoscience Center (NSC) of the University of Jyväskylä and ...
Researchers synthesize atomically precise diamond-shaped nanoclusters of silver
13-Sep-2016
A wide international collaboration involving researchers from four countries - China, Australia, Germany and Finland - have managed to synthesize and characterize two previously unknown, record-large silver nanoclusters of 136 and 374 silver atoms. These diamond-shaped nanoclusters (see Figure), ...
