Hydrogen is considered to be a very efficient and clean fuel since it is a renewable and non-polluting gas with a high energy density; thus, it has drawn much attention as an alternative fuel, in order to alleviate the issue of global warming caused by the excess use of fossil fuels. In this work, a novel Cu/ZnS/COF composite photocatalyst with a core-shell structure was synthesized for photocatalytic hydrogen production via water splitting.

Development and characterization of MAO/PLA-nHA nanocomposite coatings on pure zinc for orthopedic applications
Currently, traditional medical metal materials such as cobalt–chromium alloys, stainless steel, and titanium alloys are the main materials used for orthopedic implants because of their good chemical stability and mechanical properties. However, these inert metallic materials are difficult to degrade after damaged tissues have healed, which allows them to remain in the body for a […]
Breakthrough in Photopolymer Coatings: Improved UV Protection and Durability with Nanofiber Reinforcement
Photopolymer coatings are light-sensitive polymers that cure when exposed to ultraviolet (UV) radiation. They’re widely used in various industries, including electronics, automotive, and construction, due to their excellent adhesion, chemical resistance, and protective properties. However, conventional photopolymers often suffer from limited UV stability and mechanical weakness. This can lead to premature degradation and reduced performance, […]
Evaluation of thermal shock failure mechanism of arc-sprayed Fe-based coatings deposited on different substrates
Weak bonding between coatings and substrates can result in the failure of components subjected to high-temperature fatigue leading to substantial economic losses and lower production efficiency. Coating spalling is typical in applications where large alternating thermal cycles are present. Thus, tight bonding between coating and substrate is critical to avoid thermal failure at high temperatures. […]
