International Journal of Chemical Kinetics, EarlyView.ABSTRACT Recent experiments by Nunes et al. have demonstrated that unprecedented control of chemical reactions is possible by narrowband infrared vibrational photo‐excitation at low temperatures in inert matrices. The generated higher energy level conformers may then undergo rotamerisation and tautomerisation reactions which provide extremely useful ...

Hyperbolic Rotations With Hybrid Numbers
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper presents a geometric and algebraic analysis of hyperbolic hybrid numbers, which combine structural features of the complex, dual, and hyperbolic number systems. Based on the algebraic properties of the hybrid number set, hyperbolic rotations in both the plane and space are investigated.

Cambios y Permanencias, 2017 The practiced Marxism, in its Leninist version (and many similar), has not actually represented the doctrine of the revolutionary proletariat, but the legitimating ideology of intellectual sectors which try to impose

[Au4(dppb)3]2+ – A Planar Gold Cluster with Bright Excitation Wavelength Dependent Emission
Small, EarlyView.The first planar [Au4]2+ cluster with a deltoid geometry displays red to near‐infrared emission tunable from 700 to 918 nm. A quantum yield of 17% is observed at 770 nm upon 375 nm excitation. Excitation‐wavelength‐dependent shifts in emission reveal the involvement of multiple excited states, highlighting unprecedented photophysical versatility in ...

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3
Small, EarlyView.Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...

, 2007 : Moral relativism comes in many varieties. One is a moral doctrine, according to which we ought to respect other cultures, and allow them to solve moral problems as they see fit.

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Diorganotelluride···N Chalcogen Bonds: Analysis and Tuning of Two σ‐Holes
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Two new chalcogen bond aggregates were analyzed using single crystal X‐ray diffraction: an oligomeric ChB aggregate between bis(pentafluorophenyl) telluride and DABCO, and a monoadduct between (pentafluorophenyl)(phenyl) telluride and quinuclidine. In addition to some of the shortest intermolecular Te···N contacts reported, these structures provide ...

Relativism and Tolerance Revisited [PDF]
This paper reviews arguments concerning the relation between relativism and tolerance, both whether tolerance entails relativism, and whether relativism entails tolerance. Two new arguments are offered to support the contention that there is no necessary

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The complete series of all nine variations of complexes (DPP)MX2 (DPP = 2,5‐di(pyridin‐2‐yl)pyrrolide; M = Al, Ga, In; X = Cl, Br, I) reveals that the heavy atom effect of both the metal ion and the halide ligands promote ISC, giving rise to dual fluorescence and phosphorescence emission at 77 K. We report on the synthesis, structural characterization,
