Highlights with ‘nanoscience’

Fast Intrinsic Emission Quenching in Cs4PbBr6 Nanocrystals

Cs4PbBr6  belongs to the family of 0D metal halides, with separated and isolated [PbBr6]4- octahedra. These systems, in both nanocrystal and bulk forms, have been reported as being either non-emissive or green-emissive at room temperature...

Optical and photoluminescence properties of gold and silver nanoclusters

Silver and gold nanoclusters (NCs) have proven to be efficient and stable, with optical and emissive properties that can be tuned by changing the cluster’s geometric and electronic parameters. Due to the dependence of size,...

Transformable Polyoxometalates, Sustainable Nanoelectronics

Molecular metal oxides, or more notably polyoxometalates (POMs) are being researched for over a century. Their structure benefits from very high stability, whose inherent connectivity relies predominantly on metal-oxygen bonds. Theoretical insights into the bonding...

Unraveling the stability of ThO2 nanoclusters

In the field of nanotechnology, the ultimate goal is to produce nanostructures with specially tailored properties that contrast with those in the bulk. Actinide dioxide nanomaterials play an increasingly important role in the design of...

Fast & efficient plasmonic excitations in metallic nanoparticles

The great potential of employing tight-binding approximations after a regular DFT ground state calculation has been demonstrated in a recent paper. With the TD-DFT+TB approach (see thesis by Robert Rüger), plasmon resonances in large silver, gold,...

SCM at 9th China International OLEDs Summit

Fedor will be presenting at the Emerging Technologies 2020 conference in Shanghai. If you’re there, check out his talk in the OLEDs Summit track on January 15th. Learn how using simulations can accelerate new material...

A mechanically and electronically robust graphene-based molecular junction

A molecular device, which is both mechanically and electronically stable under operating conditions at room temperature has recently been developed. In the report in Nature Nanotechnology, researchers from Switzerland, the Netherlands, the UK, and Israel...

ReaxFF strikes back: the return of the gold nanoparticles

Their delivery power awakens In a recent combined experimental and computational study, it was shown that ReaxFF can realistically describe functonalized gold nanoparticles to understand and predict antibiotic release. This proves great promise for simulations...

Plasmon Enhanced Two Photon Absorption: Paper & Tutorial

The DIM/QM method for modeling plasmon-enhanced photochemical properties has recently been extended to several non-linear optical properties with damped cubic response theory. A recent paper by Zhongwei Hu and Lasse Jensen discusses the methods to...

Boron Nitride Nucleation through Chemical Vapor Depostion

Researchers from the University of Newcastle, Australia have used non-equilibrium ReaxFF molecular dynamics simulations to provide the first glimpse showing how boron nitride (BN) nanostructures form during boron oxide chemical vapor deposition (BOCVD) at the...
