Cost-effective, active and stable electrocatalysts are crucial for hydrogen production via electrocatalytic water splitting. Here, we describe the preparation of novel nanofibers (NF) made Ni/Gd2O3/NiO heterostructures by electrospinning. The fabricated materials showed high performance evolution reaction (HER) with onset potential values 89 mV, which very close to those platinum (Pt). NiO chem...

Three different compounds, cubic Gd2O3, orthorhombic GdGaO3, and Gd3Ga5O12 doped with Pr3+ ions were fabricated as waveguiding films by pulsed laser deposition from the same target material, (Pr:GGG) single crystal. All of them deposited at substrate temperature 800 °C. The crystalline phases obtained depend only on ambient oxygen pressure type (YAG or YAP crystals). structural texture properti...

Abstract Gadolinium-based contrast agents (GdCAs) have been the most frequently used T 1 -weighted magnetic resonance imaging (MRI) for decades. However, they serious disadvantages such as low longitudinal relaxivity value ( r ) and high dose associated-nephrotoxicity that restrict their wide applications. These emphasize need an ideal stable biocompatible CA with enhancement performance. Here,...
