Observation of a near-threshold enhancement in the Lambda Lambda-bar mass spectrum from e+ e- -> phi Lambda Lambda-bar at energies from 3.51 to 4.60 GeV; Search for new decays of psi2(3823) & process e+ e- -> pi0 pi0 psi2(3823); Study of e+ e- -> pi0 X(3872) gamma & search for Zc(4020)0 -> X(3872) gamma; Search for e+ e- -> chi_cJ pi+ pi- & a charmonium-like structure decaying to chi_cJ pi+/- between 4.18 and 4.60 GeV;
