Research ArticleOpen accessEvery word in the titleSynchrotron Powder Diffraction Study of Radiation Damage in Langmuir Blodgett Nanotemplate Crystallised ProteinJonathan P. Wright, Eugenia Pechkova, Claudio NicoliniPolycrystalline samples of lysozyme were prepared with and without a Langmuir-Blodgett (LB) thin film template via both the hanging drop method and batch crystallisation. Powder diffraction methods are used to compare these samples and to measure their resistance to radiation damage at room temperature. The X-ray induced amorphisation of the samples was followed as a function of time and it … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 12 Nov 2014 · 8,175 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModern Propulsions for Aerospace-Part IIRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Speaking about a new engine ionic means to speak about a new aircraft. The paper presents in a short time the actual engines ion chambers (called the ion thrusters) and other new ionic motors proposed by the authors. The engine (ionic propulsion unit of ions, that accelerates the positive ions through a potential difference) is approximately ten times more efficient … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 25 Apr 2017 · 8,118 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLANGMUIR-BLODGETT NANOTEMPLATE CRYSTALLIZATION COMBINED TO LASER-MICROFRAGMENTATION UNIQUELY CHARACTERIZE PROTEINS CRYSTALS BY SYNCHROTRON MICRODIFFRACTIONClaudio Nicolini, Luca Belmonte, Christian Riekel et al.Laser-induced microfragmentation of LB nanotemplate-induced protein crystals in glycerol solution results in distinct, coherently diffracting domains. Only crystals produced according to the Langmuir-Blodgett (LB) nanotemplate technique reveal in all four proteins being tested (lysozyme, insulin, thaumatin and ribonuclease) domains highly radiation resistant, while the crystals produced by the standard hanging drop crystallization method do not. Actually the very same laser … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 11 Feb 2014 · 7,984 accessesView PDF Cite
