Scientific issues of zinc-bromine flow batteries and mitigation strategies.

Zinc-bromine flow batteries (ZBFBs) are promising candidates for the large-scale stationary energy storage application due to their inherent scalability and flexibility, low cost, green, and environmentally friendly characteristics. ZBFBs have been commercially available for several years in both grid scale and residential energy storage applications. Nevertheless, their continued development still presents challenges associated with electrodes, separators, electrolyte, as well as their operational chemistry.

An audit of oxygen therapy on a respiratory ward.

Unlabelled: Oxygen therapy can be a life-saving intervention, which is widely available and commonly prescribed by medical staff. Patients often receive oxygen therapy in hospital but, like any other drug, oxygen can be dangerous when given in the wrong concentration.

Aims: To review the current literature.
