NMR signals are often too weak for many chemical and biomedical applications such as reaction monitoring or the real time investigation of metabolism in-vivo. A new method has been developed to enhance NMR signals: parahydrogen-induced...
COSMO-based model for gas solubility in polymer ionic liquids (2021 paper) Gas solubility in polymers plays an important role in processing advanced polymer materials. An important and relatively unexplored class of polymers is polymer ionic...
All biological systems are three-dimensional and determining the exact configuration of the system is important for pharmaceutical applications and drug design. However, determining 3D-structures is complicated and difficult. Vibrational circular dichroism is a method using...
Come and talk to Nick about your chemical engineering challenges at the annual AIChE meeting mid-November in Orlando. At the SCM booth (#143) he’ll be happy to discuss how the COSMO-RS module in the Amsterdam...
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...
In a recent publication Yunhan Chu et al. have presented an automated computational framework for the prediction of cellulose solubilities in ionic liquids based on COSMO-RS. The logarithmic activity coefficients and excess enthalpies were calculated...
Fast estimation of sigma profiles for high-throughput screening Thermodynamic properties of liquids and solutions can now be very quickly predicted, through fast approximations of sigma profiles through SMILES strings or xyz coordinates. These new fast...
In a recent Science paper the Gaunt group reports facile access to β-lactams via palladium-catalyzed coupling of aliphatic amines and carbon monoxide. The scope of the reaction is remarkably broad; over 40 substrates are illustrated, bearing a...
Reactive molecular dynamics simulations (ReaxFF) and X-ray photoelectron spectroscopy were used to investigate both the bulk and the surface distribution of cysteine species in aqueous solution. Experimentally, the protonation state of cysteine, which in water...
The recent cover story of Chemistry Open pursues the origin of the strong hydrogen bonds in Watson-Crick base pairs. While the commonly held theory of resonance-assisted hydrogen bonding underlying this hydrogen bond strengthening has been...
