Way, shape and form: Synthesis conditions define the nanostructure of manganese dioxide
Scientists at Tokyo Institute of Technology explore a novel and simplistic method to synthesize manganese dioxide with a specific crystalline structure called β-MnO2. Their study sheds light on how different synthesis conditions can produce manganese dioxide with distinct porous structures, ...
New method for assembling nanomaterials as desired
“Core-shell” clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient. Whether in innovative high-tech materials, more powerful computer chips, pharmaceuticals or in the field ...
By combining a ceramic material with graphene, Brown University engineers have made what they say is the toughest solid electrolyte built to date
A team of Brown University researchers has found a way to double the toughness of a ceramic material used to make solid-state lithium ion batteries. The strategy, described in the journal Matter, could be useful in bringing solid-state batteries to the mass market. "There's huge interest in ...
Risk analyses for nanoparticles
In order to reduce the number of animal experiments in research, alternative methods are being sought. This is a particular challenge if the safety of substances that have hardly been studied is to be ensured, for instance, the completely new class of nanomaterials. To accomplish just that, Empa ...
The choice of a support material may have drastic effects on the structure of the catalyst
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 ...
An unexpected property of nanometer-scale antimony crystals -- the spontaneous formation of hollow structures -- could help give the next generation of lithium ion batteries higher energy density without reducing battery lifetime. The reversibly hollowing structures could allow lithium ion ...
Largest spectral, color-tuning range from an atomically thin quantum system demonstrated
The researchers say their results, using an atomically thin material, hexagonal boron nitride, constitute a significant step forward in understanding light-matter interactions of quantum systems in 2D materials, and the journey towards scalable on-chip devices for quantum technologies. The study ...
Research team produces new nanosheets for near infrared imaging
Egyptian blue is one of the oldest manmade colour pigments. It adorns, for instance, the crown of the world famous bust of Nefertiti. But the pigment can do even more. An international research team led by Dr Sebastian Kruss from the Institute of Physical Chemistry at the University of Göttingen ...
Discovery could mean new uses for the promising nanomaterials
Ten years after producing the first sample of the now widely studied family of nanomaterials, called MXenes, Drexel University researchers have discovered a different way to make the atom-thin material that presents a number of new opportunities for using it. The new discovery removes water from ...
Scientist combine data analysis techniques with molecular dynamics simulations to understand the structure of water on material surfaces.
Understanding the various molecular interactions and structures that arise among surface water molecules would enable scientists and engineers to develop all sorts of novel hydrophobic/hydrophilic materials or improve existing ones. For example, the friction caused by water on ships could be ...
