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- ...

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: zlati nanodelci;gold nanoparticles;plasma-activated water;tunable synthesis;surfactant-free synthesis;
Plasma-activated water (PAW) enables surfactant-free synthesis of gold nanoparticles (AuNPs) at room temperature and acts as a reaction medium with tuneable reactive oxygen and nitrogen species (ROS and RNS), decoupled from the plasma discharge. Treating deionised water with an argon atmospheric-pre ...

Biofilm-associated contamination represents a persistent and costly challenge across environmental systems, causing reduced efficacy of disinfectants. Recently, nanobubbles (NBs) have shown promise for biofilm decontamination; yet, their underpinning mode of action remains a topic of debate. In this ...

Oznake:
Hexaferrite nanoplatelets exhibit size-dependent structural variations influencing their magnetic properties. Here, we synthesized Mn-substituted barium ferrite nanoplatelets via hydrothermal methods, achieving up to ∼27% Fe substitution. Advanced STEM and Raman analyses revealed depletion of Fe(2b) ...

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 ...
