An aqueous rechargeable Zn//Co3 O4 battery is demonstrated with Zn@carbon fibers and Co3 O4 @Ni foam as the negative and positive electrodes, respectively, using an electrolyte of 1 m KOH and 10 × 10(-3) m Zn(Ac)2 . It can operate at a cell voltage as high as 1.78 V with an energy density of 241 W h kg(-1) and presents excellent cycling. The battery is also assembled into a flexible shape, which can be applied in flexible or wearable devices requiring high energy.

A Zn-NiO rechargeable battery comprising a NiO nanosheet anchored to CNTs as the positive electrode, a zinc plate as the negative one and an alkaline solution of 1 M KOH and 10 mM Zn(Ac) 2 as the electrolyte is reported. It delivers a voltage of $1.75 V and a high energy density of 228 W h kg À1 (based on the mass of the positive electrode composite and zinc) with good cycling. It has great promise for practical energy storage applications. † Electronic supplementary information (ESI) available: The preparation of NiO-CNTs and NiO, CV curves of NiO-CNTs and NiO, X-ray diffraction patterns of NiO-CNTs during charge-discharge process, Nyquist plots of NiO-CNTs and NiO, cycling behaviour of NiO-CNTs and NiO, and TEM micrograph of NiO-CNTs aer 4000 full cycles.

Patients with TA are at increased risk for PH. Early screening of patients with TA with unexplained symptoms related to PH should be applied. PH-specific therapies or revascularization may be effective treatments in the early stages of patients with PA, PH, and severe pulmonary artery stenosis.
