EU Nanotech mission Japan: 14-16 February

See ADF in Action at Nanotech 2018 in Tokyo’s Big Sight! Fedor joins the EU Nanotech/SME cluster mission at the International Nanotechnology Exhibition & Conference. Come and discuss your research challenges and find out how...

Charge transport through single molecule conductors

Tetraphenylmethane tripod is a promising platform to support functional moieties considered for the fabrication of working elements in future molecular electronic devices. In this work, charge transport (conductance G) in molecular conductors supported by tetraphenylmethane...

Single material transistor from 2D PdS2

Thomas Heine and coworkers computationally designed a logical junction made from a single material, PdS2. Uniquely, 2D transition metal dichalcogenide PdS2 is semiconducting as a monolayer (ML) while it is semimetallic as a bilayer (BL). By exploiting...

Cysteine nanodroplet on a titania surface

Molecular Dynamic simulations based on a reactive force field (ReaxFF) have been shown to be the most appropriate method to characterize the adsorption of droplets of cysteine molecules on TiO2 rutile (110) slabs producing results...

Growth Mechanism of Small Endohedral Metallofullerenes

In two recent combined experimental and computational studies, the optimal cage for each endohedral metallofullerene within the families Ti@C2n and Ca@C2n has been identified and key aspects of the intriguing growth mechanisms of fullerenes were unravelled....

Relativistic and dispersion effects on O2 activation by metallic nanoparticles

In a recent study from KAUST, the effects of relativity and dispersion interactions were quantified for O2 adsorption and dissociation on Cu38, Ag38 and Au38 nanoparticles (NPs).The results indicate that the barrier for O2 dissociation almost...

Surface-enhanced Raman optical activity

Raman optical activity has proven to be a powerful tool for probing the geometry of small organic and biomolecules, but the fledgling technique of surface-enhanced Raman optical activity (SEROA) remains an experimental challenge. SEROA of...

Optical Properties of Silver and Gold Nanoparticles

In two recent papers, researchers from Trieste and Pisa studied the optical properties of silver and gold nanoparticles. The fundamental study on silver nanoshells showed that plasmonic features emerge at shells as small as 92 atoms....

Resonance hyper-Rayleigh scattering of molecules and metal clusters

Simulations of resonance hyper-Rayleigh scattering (HRS) for molecules and metal clusters in both resonance and off-resonance regions have been studied using TDDFT, with a new implementation by the ADF development groups of Lasse Jensen and...
