Background: Optimal nutrition for lactating mothers has remained at the top of the health policy agendas of many developing countries because of the consensus that it is an effective channel for achieving positive maternal and child health outcomes. Objectives: This study draws on the socio-ecological theory to explore barriers and enablers of healthy eating among lactating mothers in the Wa West District of Ghana.

This study analyzes hydrogen production using photoelectrochemical (PEC) water splitting methods for Ga-doped ZnO electrodes coated on stainless steel. Physical electrochemistry, electrochemical impedance, hydrogen production, X-ray diffraction (XRD), and scanning electron microscopy (SEM) analyses are performed on uncoated, undoped ZnO-coated, and Ga-doped ZnO-coated electrodes. The parameters of the best-coated electrode obtained by chronoamperometry (CA) analysis are as follows: the electrode is immersed in a dip-coating bath for 4 s, is coated five times, and has a doping ratio of 1%.

The biomechanical behavior and corrosion phenomena of porous metallic implants can compromise their clinical success. This work proposes modifying the surface of c.p. titanium scaffolds manufactured by 3D-printing (Direct Ink Writing), depositing a thin film of a β-Ti alloy (Ti-35Nb-7Zr-5Ta) using the High-Power Impulse Magnetron Sputtering (HiPIMS) technique. The versatility of this technique has enabled the fabrication of conformal coatings with uniform thickness, excellent adhesion, a nanorough surface, and a homogeneous columnar distribution.
