An international team of scientist of Peter the Great St.
Petersburg Polytechnic University (SPb PU), Leibniz University Hannover (Leibniz Universität Hannover) and the Ioffe Institute report a way to improve nanocomposite ... By doping alumina crystals with neodymium ions, engineers at the University of California San Diego have developed a new laser material that is capable of emitting ultra-short, high-power pulses—a combination that could ...
Polymer plastic solar cells remain an industry priority because of their light weight, flexibility and cost-effectiveness.
Now scientists from Stony Brook University and the U. Department of Energy's (DOE) Brookhaven National ...
The first version was released in 1988 and then seven next versions have followed: CRYSTAL92, CRYSTAL95, CRYSTAL98, CRYSTAL03, CRYSTAL06, CRYSTAL09 and CRYSTAL14.
The CRYSTAL program computes the electronic structure of periodic systems within Hartree Fock, density functional or various hybrid approximations (global, range-separated and double-hybrids).
In their paper published in the journal Science, the group describes the technique ...The Bloch functions of the periodic systems are expanded as linear combinations of atom centred Gaussian functions.Powerful screening techniques are used to exploit real space locality.A team of researchers at Southeast University in China has found a way to make metal-free perovskites in a useable form. Gladysz has been mixing metals and carbon to create novel molecules, from the world's longest molecular wires to microscopic gyroscopes controllable by cage size, molecular ...In their paper published in the journal Science, the group describes their technique and how well it ... As allergy season intensifies, many people are cursing pollen—the powdery substance released by plants for reproduction.
