Reconciling Experiment with Quantum Chemical Calculations: Electron Iso-Density Surfaces Represent Atomic and Molecular Surfaces [PDF]
The surface area of atoms and molecules plays a crucial role in shaping many physiochemical properties of materials. Despite its fundamental importance, precisely defining atomic and molecular surfaces has long been a puzzle.

Nonthermal phase transitions in semiconductors induced by a femtosecond extreme ultraviolet laser pulse [PDF]
Part of Focus on High Energy Density Physics. In this paper, we present a novel theoretical approach, which allows the study of nonequilibrium dynamics of both electrons and atoms/ions within free-electron laser excited semiconductors at femtosecond time

The zw -type 32CA reactions of nitrones with ketenes are controlled by the nucleophilic character of the nitrone and the electrophilic character of the ketene. They are chemo- and regio-selective and the use of electrophilic ketenes changes the mechanism from one-step to two-step.

Electronic transport in metal-molecular nanoelectronic networks: A density functional theory study [PDF]
Electronic transport properties of nanoscale networks composed of interconnected molecules/gold nanoclusters are examined via first-principles plane wave scattering density functional theory-based simulations. Au-molecular (benzene/alkanedithiol) junctions and networks, connected in linear chains and Y-, H- and ring-shaped networks were studied ...

Ring closing reaction in diarylethene captured by femtosecond electron crystallography [PDF]
The photoinduced ring closing reaction in diarylethene, which serves as a modelsystem for understanding reactive crossings through conical intersections, was directly observed with atomic resolution using femtosecond electron diffraction.

The electron density: experimental determination and theoretical analysis [PDF]
Two related lines of research in experimental electron density determination are reported in this thesis. In the first case, the well-proven and popular multipole modeling technique is applied to three high resolution, single-crystal X-ray diffraction ...

Ergo: An open-source program for linear-scaling electronic structure calculations
Ergo is a C++ program for all-electron Hartree–Fock and Kohn–Sham density functional theory electronic structure calculations using Gaussian basis sets. The program uses algorithms for which the computational cost increases linearly with system size for ...
