Multifrequency Multiresonance EPR Investigation of Halogen-bonded Complexes Involving Neutral Nitroxide Radicals

, 2017
Halogen-bonded complexes with neutral nitroxide radicals as the Lewis base have been investigated in liquid and frozen solutions by multifrequency CW and pulse EPR spectroscopies, including ENDOR and ELDOR-detected NMR (EDNMR) techniques.

The Efficacy of Feed Restriction Program on Broiler Production: A Review

Ibn Al-Haitham Journal for Pure and Applied Sciences
Poultry often intake energy to meet their energy needs, which is associated with both more fat and protein deposition, which is also conditioned by the presence of adequate other nutritional nutrients.

Estimating the strength of bi-axially loaded track and channel cold formed composite column using different AI-based symbolic regression techniques

Scientific Reports
Steel construction is increasingly using thin-walled profiles to achieve lighter, more cost-effective structures. However, analyzing the behavior of these elements becomes very complex due to the combined effects of local buckling in the thin walls and ...

Sterisch überfrachtete Alken‐Photo‐Redox‐Schalter auf Basis von Chinolinium/Carben Bausteinen

Angewandte Chemie, EarlyView.
Eine modulare Synthese einer neuen Klasse von Photo‐ und Redox‐Schaltern wird beschrieben, die auf der Kombination von Chinoliniumsalzen und Carbenen basiert. Das photochemische Schalten ermöglicht einen selektiven Wechsel zwischen gefalteten E/Z‐Isomeren, während das elektrochemische Schalten den Wechsel zwischen neutralen, radikalkationischen und ...

In vitro analysis of redox status of normal and tumor cells using nitroxide radicals and EPR spectroscopy

, 2014
In present study we describe in vitro imaging analysis of cellular redox status in cancer and noncancer cells, using two redox-sensitive nitroxide derivatives (methoxy-TEMPO and mito-TEMPO) and electron paramagnetic resonance (EPR) spectroscopy.

Asymmetric α‐Alkylation With Activated and Unactivated Electrophiles by a Highly Productive and Recyclable Lewis Acid/Imidazolium Catalyst

Angewandte Chemie International Edition, EarlyView.
An air‐stable, easily prepared, bifunctional Cu(II)/imidazolium complex enables highly enantioselective α‐alkylation of 1,3‐dicarbonyls with outstanding productivity (TON up to 1740). Highlights include broad electrophile scope spanning π‐activated and nonactivated reagents, stereo‐retentive allylation, simple catalyst synthesis, and efficient catalyst
