Crystal structure of (2E)-1-(5-bromothiophen-2-yl)-3-(2-chlorophenyl)prop-2-en-1-one
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title compound, C13H8BrClOS, the thienyl ring is not coplanar with the benzene ring, their planes forming a dihedral angle of 13.2 (4)°. In the crystal, molecules stack along the a axis, with the interplanar separation between thienyl rings and ...

, 2002 Biological cells in soft materials can be modeled as anisotropic force contraction dipoles. The corresponding elastic interaction potentials are long-ranged ($\sim 1/r^3$ with distance $r$) and depend sensitively on elastic constants, geometry and ...

Crystal structure of dichlorido{2,6-bis[(3-phenyl-1H-pyrazol-1-yl)methyl]pyridine}cobalt(II)
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title complex, [CoCl2(C25H21N5)], the CoII atom is coordinated by two Cl atoms and two N atoms, provided by a tridentate pyrazolylpyridyl ligand, forming a slightly distorted tetrahedral geometry [range of angles: 96.51 (10) (chelate ring) to 118 ...

Island formation without attractive interactions [PDF]
, 2008 We show that adsorbates on surfaces can form islands even if there are no attractive interactions. Instead strong repulsion between adsorbates at short distances can lead to islands, because such islands increase the entropy of the adsorbates that are ...

Constraining anomalous Higgs interactions
, 2012 The recently announced Higgs discovery marks the dawn of the direct probing of the electroweak symmetry breaking sector. Sorting out the dynamics responsible for electroweak symmetry breaking now requires probing the Higgs interactions and searching for ...

CP, T and fundamental interactions [PDF]
, 2012 We discuss the importance of the CP (simultaneous particle-antiparticle and left-right permutation) and T (time reversal) symmetries in the context of fundamental interactions.

Journal of ChemistryThe propensity of halogen-bearing molecules (XF3) in a T-shaped geometry to interact with Lewis bases (LBs) and thereby engage in π-hole interactions in the fashion of F3X⋯LBs (where X = Cl, Br, and I; LB = NH3, N2H2, and N2) complexes was studied using ...

Crystal structure of 1-methoxypyrene
Acta Crystallographica Section E: Crystallographic Communications, 2015 The title compound, C17H12O, crystallized with three independent molecules (A, B and C) in the asymmetric unit. In the crystal, the three independent molecules are linked by π–π interactions [centroid–centroid distances = 3.551 (3)–3.977 (2) Å], which ...

Phenomenological Lambda-Nuclear Interactions
, 2002 Variational Monte Carlo calculations for ${_{\Lambda}^4}H$ (ground and excited states) and ${_{\Lambda}^5}He$ are performed to decipher information on ${\Lambda}$-nuclear interactions.
