Background: Friction and wear are one of the major causes of failure of mechanism and machines in the field of Engineering. To overcome this problem, lubricants are provided in the engineering system. Lubricants are derived from synthetic hydrocarbon blends or mineral oils. Lubricants help to minimize friction and wear in contacting surface in order to reduce friction and minimize power loss. In certain situation, lubrican Read More

Background: The interest for polymeric nanogels is entirely justified taken into consideration their diversity brought by the composition and their multiple applications, especially in the biomedical field. Nanogels can be defined as three-dimensional networks with interconnected pores and diameters below 100 nm. These materials exhibit distinct properties like swellability which can be useful for entrapping and further relea Read More

Background: Heterojunction interface effect and wide light absorption are attracting many attentions for environmental application. Reduced Graphene Oxide (RGO)/semiconductor hybrids have showed very high photocatalytic activity than single one. RGO/CuS hybrids should be a competitive material with highly photocatalytic activity. Objective: This work focused on the synthesis and photocatalytic activity of the C Read More

Background: Injection mould has become an important industry. The traditional method of optimizing a product through artificial experience has been unable to meet the needs of the market. Moldflow can be used for defect analysis before injection molding. Objective: The external barrel of washing machine of injection process analysis was presented by Moldflow. Methods: Molding process of the external barrel of washing m Read More

Background: Light Weight High Entropy Alloys (LWHEAs). Objective: The purpose of this article is to report the processing challenges we have faced during the development of LWHEAs and to highlight the alloys compositions which can be successfully processed. Method: Both liquid and solid phase processing techniques were attempted to synthesize LWHEAs. Results: A total of 12 HEA compositions were processed in the curr Read More

Background: Subcritical crack growth is one of the main time-dependent behaviors in rocks. Double torsion testing has been adopted to determine subcritical crack propagation parameters for granite specimens during water interaction, the crack growth time dependence of granite is also discussed on the basis of fracture mechanics. Objective: The purpose of this article is to study the time dependent failure characteristic Read More

Background: The applications of the clay minerals in the various process industries are still relevant and closely related to their structure and composition. Objective: To study ways of selection, purification and subsequent modification of mineral clays to ensure a specific industrial use, being proposed, developed and applied a separation method of clay fractions called elutriation. Method: A granted process was based o Read More

Background: The development of resource and energy effective schemes for processing natural raw materials attracts increasing attention in the last decades. The scheme of the integrated processing of natural high-magnesian siderites (res. of 1 billion tonnes) developed and patented by our team allows obtaining several end products, the main of which are low-magnesian iron ore concentrate (Fetotal ≥ 58-60%, MgO ≤ 6-8% Read More
