Enhanced Corrosion Resistance in Aluminum-Based Electrolyzer Components via Stoichiometry Tuned Atomic Layer-Deposited TiO Films.

Titanium (Ti) is widely used as anode current collectors in proton exchange membrane (PEM)-based water electrolyzers due to its self-passivated oxide layer, which protects it from corrosion in acidic solutions. However, the cost of the material and machining process for Ti is high. A wider utilization of water electrolyzers to produce hydrogen could be favored by the use of less expensive coated aluminum (Al) substrates, which could potentially replace high-cost Ti-based components.

Community participation and private sector engagement are fundamental to achieving universal health coverage and health security in Africa: reflections from the second Africa health forum.

Background: Inadequate access to quality health care services due to weak health systems and recurrent public health emergencies are impediments to the attainment of Universal Health Coverage and health security in Africa. To discuss these challenges and deliberate on plausible solutions, the World Health Organization Regional Office for Africa, in collaboration with the Government of Cabo Verde, convened the second Africa Health Forum in Praia, Cabo Verde on 26-28 March 2019, under the theme Achieving Universal Health Coverage and Health Security: The Africa We Want to See.

Methods: The Forum was conducted through technical sessions consisting of high-level, moderated panel discussions on specific themes, some of them preceded by keynote addresses.
