Article Synopsis
- Multiple sclerosis is a serious disease where the immune system attacks the central nervous system, causing inflammation.
- Scientists found that a substance made by gut bacteria, called indole-3-carboxaldehyde (3-IAld), seems to help with this disease by affecting how the body uses a chemical called tryptophan.
- This process could protect the body and might even lead to new treatments for autoimmune diseases like multiple sclerosis.
In this paper, an investigation of the properties of Cu and Cu/MgO nanoparticles (NPs) is presented. The NPs were obtained with gas-phase synthesis, and the MgO shells or matrices were formed via the co-deposition method on inert substrates. SEM and AFM were used to investigate the NP morphology on Si/SiO, quartz, and HOPG.

Nevertheless, the application of graphene is known to modulate frictional dissipation by inducing local strain. This work reports on the nanomechanics of graphene conformed on different textured silicon surfaces that mimic the cogs of a nanoscale gear.

- The study focuses on using magnetron-sputtering to create controlled metal nanoparticles, specifically Ag/MgO, for improved perovskite solar cells.
- The Ag nanoparticles are deposited on a glass/FTO/TiO substrate, which is essential for the solar cell's front electrode, and their structural and oxidation resistance is thoroughly examined.
- Optimizing the nanoparticle coverage leads to a significant 5% increase in power conversion efficiency, achieving a total efficiency of 17.8% for the engineered solar cells.
The piezoelectric response of ZnO thin films in heterostructure-based devices is strictly related to their structure and morphology. We optimize the fabrication of piezoelectric ZnO to reduce its surface roughness, improving the crystalline quality, taking into consideration the role of the metal electrode underneath. The role of thermal treatments, as well as sputtering gas composition, is investigated by means of atomic force microscopy and x-ray diffraction.
