Facile synthesis route for bulk production of complex fullerene-like MoS[sub]2 nanostructures with enhanced tribological properties
Aljaž Drnovšek, Damjan Vengust, Patrik Šumandl, Domen Korbar, Aleš Mrzel, Mojca Vilfan
Izvirni znanstveni članek
Oznake: nanocevke;sinteza;nanodelci;nanotubes;nanoparticles;synthesis;
Molybdenum-based nanoparticles are often used as oil additives to enhance a material’s tribological performance. Here, we present a highly efficient synthetic route for the bulk production of two types of MoS2 nanostructures: multi-wall nanotubes and fullerene-like nanostructures. The presented two- ...

Efficient decoration of graphene oxide with a narrow size distribution of noble metal nanoparticles
Daniele Vella, Damjan Vengust, Polona Umek, Ali Rezaei, Matija Jezeršek, Aleš Mrzel
Izvirni znanstveni članek
Oznake: grafenov oksid;nanodelci;nanokompoziti;graphene oxide;decoration;nanoparticles;nanocomposites;
We have developed a significantly enhanced method for the effective and homogeneous decoration of graphene oxide (GO) and reduced graphene oxide (r-GO) flakes with gold (Au) and platinum (Pt) nanoparticles. This method involves the direct nucleation of nanoparticles on the surface of dispersed GO th ...

Plasma-tunable metasurfaces for SERS nanosensing of hazardous chemicals
Vasyl Shvalya, Andrii Breus, Oleg Baranov, Damjan Vengust, Janez Zavašnik, Uroš Cvelbar
Izvirni znanstveni članek
Oznake: plasmonic sensors;surface enhanced Raman scattering;
The demand for rapid, field-deployable detection of hazardous substances has intensified the search for plasmonic sensors with both high sensitivity and fabrication simplicity. Conventional approaches to plasmonic substrates, however, often rely on lithographic precision or complex chemistries limit ...

Oznake: DNA genomic ration;plasma electrochemical reduction;coupled plasmonic nanogold;DNA Raman fingerprints;
It is shown that surface-enhanced Raman spectroscopy (SERS) can identify bacteria based on their genomic DNA composition, acting as a “sample-distinguishing marker”. Successful spectral differentiation of bacterial species was accomplished with nanogold aggregates synthesized through single-step pla ...

Nanoplastics, an increasingly concerning environmental pollutant, are extremely difficult to detect using conventional analytical techniques. Many methods fail in this regard, but surface-enhanced Raman scattering (SERS) offers a promising solution by utilising specialised nanostructures that amplif ...
