We study e+e-→π+π-hc at center-of-mass energies from 3.90 to 4.42 GeV by using data samples collected with the BESIII detector operating Beijing Electron Positron Collider. The Born cross sections are measured 13 and found be of same order magnitude as those e+e-→π+π-J/ψ but a different line shape. In π±hc mass spectrum, distinct structure, referred Zc(4020), is observed 4.02 GeV/c2. Zc(4020) carries an electric charge couples charmonium. A fit invariant neglecting possible interferences,...

The X(1835), which was previously observed by BESII, confirmed with statistical significance that larger than 20σ. In addition, π(+)π(-)η(') invariant-mass spectrum, X(2120) X(2370), are significances 7.2σ 6.4σ, respectively. For angular distribution radiative photon consistent expectations for pseudoscalar.
Abstract To accelerate the pace in field of photothermal therapy (PTT), it is urged to develop easily accessible agents (PTAs) showing high conversion efficiency (PCE). As a proof‐of‐concept, hereby conventional strategy presented prepare donor–acceptor (D–A) structured PTAs through cycloaddition‐retroelectrocyclization ( CA–RE ) reaction, and resultant give PCE upon near‐infrared (NIR) irradiation. By joint experimental‐theoretical study, these exhibit prominent D–A structure with strong...
Platinum-based chemotherapy drugs play an indispensable role in clinical cancer treatment, but exhibit considerable side effects due to their non-specific mechanism of killing cells and normal cells. In this regard, the use antibodies conjugated anti-cancer platinum complexes will enable better differentiation from Here, six pincer-platinum(II) NHC (N-heterocyclic carbene) are reported, one which has amino group on N-alkyl ligand.
