Electron diffraction pattern of PbS nanoparticles in zeolite X
Optical and structural properties of PbS nanoparticles produced in Zeolite Na-X
The study of semiconductor nanoparticles embedded in a matrix is currently a very active research area. These small particles have physicochemical properties quite different from those in the bulk material. A great variety of semiconductors nanoparticles have been synthesized in different matrix such as polymers, glasses and zeolites with the main purpose to modify their properties by controlling the particle size. Alterations to these properties mean they can be tailored to specific applications in the fields of non-linear optics, photovoltaic conversion, catalysis, optoelectronics, etc.
In this work, published in AZojomo*, by M. Flores-Acosta, R. Pérez-Salas, M. Sotelo-Lerma, F. F. Castillón-Barraza and R. Ramírez-Bon from Unidad Querétaro, Universidad de Sonora and Universidad Nacional Autónoma de México, PbS nanoparticles were synthesized in zeolite Na-X by means of ionic exchange processes in alkaline aqueous solutions. They reported the optical and structural properties of the system PbS-Na-X zeolite.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
