A reparameterization of the torsional parameters for the glycosidic dihedral angle, chi, for the AMBER99 force field in RNA nucleosides is used to provide a modified force field, AMBER99chi. Molecular dynamics simulations of cytidine, uridine, adenosine, and guanosine in aqueous solution using the AMBER99 and AMBER99chi force fields are compared with NMR results. For each nucleoside and force f...

Materials performance is central to the satisfactory operation of current and future nuclear energy systems due to the severe irradiation environment in reactors. Searching for structural materials with excellent irradiation tolerance is crucial for developing the next generation nuclear reactors. Here, we report the irradiation responses of a novel multi-component alloy system, high entropy al...

Interest in tritium toxicity stems from concern not only with 3H from small sources-its widespread use in research, for example, and in luminous paints (there have already been deaths from tritium exposure in the luminous paint industry)-but from the large source: nuclear energy. Tritium is a prominent by-product of nuclear fission, difficult and costly to contain, and impressive quantities fin...
