Parametrizing GFN1-xTB for hybrid perovskites
Halide perovskites are promising materials for optoelectronic applications in solar cell devices due to their excellent optoelectronic performance. However, they suffer from several dynamical degradation problems, which are difficult to characterize. Atomistic simulations can provide...
Thermal Management: Conductivity of 2D Covalent Organic Frameworks with Nanopores
Managing temperatures is essential for the lifetime and performance of many materials and their devices. Two main applications include electronic devices and spacecraft. Covalent organic frameworks (COFs) are crystalline porous polymers, with tunable properties such...
COSMO-RS Aided Design of New, Natural Deep Eutectic Solvents for CO2 Capture
CO2 capture from power plants is regarded as an effective midterm solution to reduce anthropogenic greenhouse gas emissions. In the case of an integrated gasification combined cycle (IGCC) power plant with precombustion CO2 capture, the...
Systems Inorganics: Finding a Needle in a Haystack
In computational mass spectrometry, one often tackles the problem of correlating a mass spectrometry signal to a viable and chemically sound structure. Although such problems are commonly solved in organic chemistry, sometimes even with simple...
Ultalight aerogels from protein aggregate pyrolysis – experiments and ReaxFF simulations
The integration of two-dimensional (2D)-graphene (G) and one-dimensional (1D) carbon fibers (CF) has excellent potential as a new type of carbon structure. Yet, it remains largely unexplored mainly because of the inability to fabricate such...
Large-scale self-consistent GW-Bethe-Salpeter-Equation calculations in ADF
The GW-Bethe-Salpeter Equation (BSE) (GW-BSE for short) is a state-of-the-art approach to calculate low-lying vertical excited states of molecular systems. Compared to Time-Dependent Density Functional Theory (TDDFT), it offers major improvements in the description of charge-transfer...
A new auxiliary basis set for (almost) all the elements of the periodic table optimized for accurate and fast TDDFT calculations
Recently, a new algorithm, polTDDFT, to solve the TDDFT equations for large systems has been proposed and implemented in ADF [1]. PolTDDFT is a valid alternative to the Casida – Davidson approach when a very...
Fast and accurate correlation energies with RPA + SOSEX
The Random Phase Approximation (RPA) is a state-of-the art method for the accurate description of electron correlation effects, which does not suffer from the divergences of MP2 for large molecules and small HOMO-LUMO gaps. However,...
New high-performance electrolyte for Mg-based batteries
Magnesium-based batteries are being actively researched, with Mg being more abundant and having a higher theoretical energy density than Li. Consequently, suitable electrolytes for magnesium-ion batteries are being actively pursued. A recent publication introduced a...
