Selectivity In The Synthesis Of Cyclic Sulfonamides

The most important outcome is the derivation of explicit relationships between the structure of the grid, the optimal transmission and distribution of energy, and the grid’s collective behavior (namely, the synchronous generation of power).These relationships are extremely relevant for the design of resilient power-grid models. This work tackles the problems of understanding how energy is transmitted and distributed in power-grids as well as in determining how robust this transmission and distribution is when modifications to the grid or power occur.

The work presented here suggests the promise for MAGIS as a viable alternative to the calutrons.This thesis describes a proof-of-principle experiment demonstrating a technique for stable isotope enrichment called Magnetically Activated and Guided Isotope Separation (MAGIS).

Photofunctionalization of Molecular Switch Based on Pyrimidine Ring Rotation in Copper Complexes The finding elucidated here holds promise for handling the photoprocesses of metal complexes, valid for both applications and novel properties. Both the functions and the procedures for proving these phenomena are beneficial for the development of more functionalized systems based on material science, molecular science, nanoscience, nanotechnology, electrochemistry, photochemistry, coordination chemistry, physical chemistry, and related disciplines.

This thesis analyses how supersymmetric (SUSY) extensions of the Standard Model (SM) of particle physics can be constrained using information from Higgs physics, electroweak precision observables and direct searches for new particles..

Despite the enormous amount of work on the tunneling of a single particle through a barrier, we know very little about how a system made of several or of many particles tunnels through a barrier to open space. The present work uses numerically exact solutions of the time-dependent many-boson Schrödinger equation to explore the rich physics of the tunneling to open space process in ultracold bosonic particles that are initially prepared as a Bose-Einstein condensate and subsequently allowed to tunnel through a barrier to open space. Tunneling Dynamics in Open Ultracold Bosonic Systems The many-boson process exhibits exciting collective phenomena: the escaping particles fragment and lose their coherence with the source and among each other, whilst correlations build up within the system..

Controlling Synchronization Patterns in Complex Networks Synchronization is a ubiquitous phenomenon observed in different contexts in physics, chemistry, biology, medicine and engineering.

We discovered an interesting regioselectivity in an intramolecular Heck reaction, which we studied for a series of substrates that are unbiased in terms of the size of the newly formed ring, where very high levels of selectivity in relation to the new carbon-carbon bond are typically observed.

By using a unique combination of iron catalyst and dichloride oxidant, various kind of naphthalene and phenanthrene derivatives were synthesized via annulation reaction with alkynes including direct C–H bond activation process.

Selectivity in the Synthesis of Cyclic Sulfonamides DFT calculations were performed to attempt to shed light on the reaction sequence. We discovered an interesting regioselectivity in an intramolecular Heck reaction, which we studied for a series of substrates that are unbiased in terms of the size of the newly formed ring, where very high levels of selectivity in relation to the new carbon-carbon bond are typically observed.
