A magnetic field can be used to switch nanolasers on and off, shows new research from Aalto University. The physics underlying this discovery paves the way for the development of optical signals that cannot be disturbed by external disruptions, leading to unprecedented robustness in signal processing.
Ever since graphene – a thin carbon sheet just one-atom thick – was discovered more than 15 years ago, the wonder material became a workhorse in materials science research.
Researchers have incorporated phosphorene nanoribbons into new types of solar cells, dramatically improving their efficiency.
The increasing concentration of organic and inorganic pollutants could effectively be controlled by a combination of bioremediation and nanotechnology, according to the latest research in the Journal of Hazardous Materials.
Nanodiamonds may be tiny, but they can help with one of the biggest problems facing humanity today: Climate change.
In a recent study published in the journal Nano-Micro Letters, researchers from China developed a polymer-based hierarchically multifunctional polyimide composite film comprising of layers of 61.0 weight% graphene oxide/expanded graphite, 23.8 weight% ferric oxide/polyimide, and polyimide fibers to be used as a flexible, heat-dissipating, and electromagnetic interference (EMI) shielding film for electronic devices.
A group of researchers from Spain developed a quasi-3D photonic crystal-based encapsulation for cesium lead halide (CsPbX3) perovskite nanocrystals for use in optoelectronic devices.
In a recent study published in the journal ACS Sustainable Chemistry & Engineering, researchers replaced organic semiconductor materials like graphene oxide substrates with metal-free cellulose nanofiber-based polymer substrate in surface-enhanced Raman spectroscopy (SERS) to analyze organic porphyrin-type molecules.
The COVID-19 pandemic has prompted scientific collaborations and advances in the fabrication of antimicrobial and antiviral surface coatings; a key tool in minimizing and ideally mitigating viral and bacterial transmission to, from, and between human beings.
A novel study published in Diamond and Related Materials is focused on a novel technique that utilizes fast combustion to synthesize carbon nanostructures. A simple technique for the rapid and autothermal creation of several forms of nanocarbon, including a 3D graphene-like nanosystem, has been demonstrated using combustion formulation.
