This paper addresses the problem of consistent energy-based coupling of atomistic and continuum models of materials, limited to zero-temperature statics of simple crystals. It has been widely recognized that the most practical coupled methods exhibit large ...
Cross coupling of non-activated alkyl halides is a potentially transformative methodology in organic synthesis. Herein we review the recent development of nickel-catalyzed coupling of non-activated alkyl halides. The current understanding of the mechanism ...
Brillouin scattering is particularly efficient and attractive for the implementation of strain and temperature distributed sensing in optical fibres. Recently a trend has been observed that modern advanced applications require a substantial step towards be ...
Ni-catalyzed Sonogashira coupling of nonactivated, β-H- containing alkyl halides, including chlorides, is reported. The coupling is tolerant to a wide range of functional groups, including ether, ester, amide, nitrile, keto, heterocycle, acetal, and aryl h ...
Two new aminophosphines, benzyl-N(Ph2P)(2) and 2-picolyl-N(Ph2P)(2), have been synthesized. Oxidation of the aminophosphines with either hydrogen peroxide, elemental sulfur and selenium gave the corresponding oxides, sulfides and selenides benzyl-N(Ph2P=E) ...
An investigation is performed of the possibility of achieving simultaneous distributed strain and temperature sensing based on hybrid Raman–Brillouin scattering with the use of multi-wavelength optical sources such as common Fabry–Perot (FP) lasers. By emp ...
Non-activated alkyl halides are challenging substrates for cross-coupling reactions because they are reluctant to undergo oxidative addition and because metal alkyl intermediates are prone to β-H elimination. Despite recent progress, well-defined catalysts ...
A general and straightforward protocol for the cross-coupling of non-activated alkyl halides with heterocyclic CH bonds has been developed. The transformation is chemo- and regioselective and many functional groups on both coupling partners are tolerated. ...
The nickel pincer complex 1 catalyzes the cross-coupling of the title compounds with remarkable substrate scope and functional group tolerance. A nickel/alkynyl species was isolated and shown to be catalytically competent. THF=tetrahydrofuran, O-TMEDA=bis[ ...
The electro-mechanical coupling and resonance characteristics of a piezoelectric modulated thin film bulk acoustic wave resonator (PMBAR) is described quantitatively. The derived 1-D analytical model is in agreement with 2-D finite element modeling (FEM). ...
