Spinning around in Transition-Metal Chemistry.
The great diversity and richness of transition metal chemistry, such as the features of an open d-shell, opened a way to numerous areas of scientific research and technological applications. Depending on the nature of the metal and its environment, there are often several energetically accessible spin states, and the progress in accurate theoretical treatment of this complicated phenomenon is p...
متن کاملLaser-assisted metal spinning for an efficient and flexible processing of challenging materials
The demand for components made from high performance materials like titanium or nickel-based alloys as well as strain-hardening stainless steel is steadily increasing. However, conventional forming operations conducted on these materials are generally very laborious and time-consuming. This is where the limitations of metal spinning also become apparent. Using a laser to apply heat localized to...
متن کاملKnot spinning
This exposition is intended to provide some introduction to higher-dimensional knots embeddings of Sn−2 in S through spinning constructions. Once our shoe laces, those archetypical hand tools of knot theory, have been turned into spheres, how can we construct and visualize concrete examples of such knots? There are many important ways to construct higher-dimensional knots. If we are interested ...
متن کاملEnergy Spectra of spinning particles around spinning strings in
Riemannian Killing conserved currents are used to find the energy spectra of classical spinning particles moving around a spinning string in Einstein-Cartan (EC) theory of gravity. It is shown that a continuos spectrum is obtained for planar open orbits while a discrete spectrum is obtained for circular planar orbits. A spin-spin effect between the spin of the test particle and the spin of the ...
متن کاملModified Linear Theory for Spinning or Non-Spinning Projectiles
Static and dynamic stability are the most important phenomena for stable flight atmospheric motion of spin and fin stabilized projectiles. If the aerodynamic forces and moments and the initial conditions are accurately known, an essentially exact simulation of the projectile’s synthesized pitching and yawing motion can be readily obtained by numerical methods. A modified trajectory linear theor...
