One‐Step and Universal Strategy for the Synthesis of Hypermodified Uracil Phosphoramidites acp3U and cmnm5U

Chemistry – A European Journal, EarlyView.
One‐step, highly efficient, and scalable synthesis of acp3U phosphoramidite is described, as well as a new alternative synthesis of cmnm5U phosphoramidite from a highly versatile intermediate. Latter could be scaled‐up, split, and aliquots turned simultaneously into cmnm5U, nm5U, and mnm5U.

الفلسفة الايكولوجية عند هانز يوناس "نحو أخلاق جديدة لمستقبل الطبيعة والإنسانية"

مجلة الآداب و العلوم الإجتماعية, 2018
تنتقد الفلسفة الايكولوجية عند هانز يوناس الفلسفات التقليدية لأنها كَرَّسَت فكرة "المركزية البشرية" من خلال تمييزها بين الإنسان والطبيعة وأعطته حق السيطرة عليها.كما تنتقد الفعل الإنساني المعاصر الذي زاد تدخله في الطبيعة مُستَعِينًا في ذلك بالتقدم العلمي ...

Structural Aspects of Lithium‐Ion Conduction in the Phosphidotitanate Li8TiP4 and Its Comparison With Li7+5xTa1−xP4 and Li8−xTi1−xTaxP4

Chemistry – A European Journal, EarlyView.
ABSTRACT The chemical system Li/Ti/P has previously been subject to intensive investigation. However, reliable structural data for the reported phases have remained elusive. Motivated by the growing interest in phosphorus‐based lithium‐ion conductors, we have reinvestigated the synthesis, crystal structure, and physical properties of Li8TiP4.

Phonon-induced resistance oscillations of two-dimensional electron systems drifting with supersonic velocities

, 2010
We present a theory of the phonon-assisted nonlinear dc transport of 2D electrons in high Landau levels. The nonlinear dissipative resistivity displays quantum magneto-oscillations governed by two parameters which are proportional to the Hall drift ...
