We study the processes e+e−→π+π−π0π0π0π0γ and π+π−π0π0π0ηγ in which an energetic photon is radiated from initial state. The data were collected with BABAR detector at SLAC National Accelerator Laboratory. About 7300 870 events, respectively, are selected a sample corresponding to integrated luminosity of 469 fb−1. invariant mass hadronic final state defines effective e+e− center-of-mass energy....

a new proton transfer compound, formulated as (hamp-6-pic)(hpyzd) ∙h2o (1), has been synthesized from the reaction of pyrazine-2,3-dicarboxylic acid (h2pyzd)  and 2-amino-6-methyl pyridine (amp-6-pic), in 1:1 molar ratio. extensive o−h×××o, n−h×××n and o−h×××o hydrogen bonds involving (hamp-6-pic)+ cation, (hpyzd)- anion and co-crystal water molecule٫ static electronic٫ and π…π stacking interac...

Introduction: Hand and wrist stability are critical for optimal upper extremity function. Instability occurs when injury or a pathological condition alters balance, typically in the basketball players and handball players. Injury also can occur whenever the ligaments are subjected to tensile forces that exceed their physiological capacities. For example, thumb is stable in ext...

Two Zn(II) coordination polymers, viz., [Zn2Cl2(H2O)2(µ-4-AmBz)2]n (1) and [ZnCl2(µ-3-AmPy)2]n (2) (4-AmBz = 4-aminobenzoate, 3-AmPy 3-aminopyridine) have been prepared at room temperature characterized using elemental analysis, FT-IR, electronic spectroscopy, TGA (thermogravimetric analysis) single crystal XRD. Crystal structure analyses of the polymers unfold presence non-covalent anion–π, π-...
