Ideal gas heat capacities are important for the calculation of caloric properties of real fluids. But as shown in the past, they are not always available with required accuracy or are still lacking. In this pape
The alteration in mineralogy is a fundamental facet of material change. Here, chemical dissolution acts as a force to selectively removing soluble minerals from the solid matrix. This not only impacts the mineral composition but also modifies the mechanical and physical properties of the geomaterial....
Element 1 will cover the properties of materials Element 2 will address the relationship between manufacturing process and materials behaviour Element 3 will cover the failure of materials Block 3 Heat Transfer and Combustion Assessment consists of a small number of questions which require a blend of...
further research is still needed to assess their real durability, wear behaviour in the oral environment, bioactive potential, and mechanical, biological and optical properties. Thus, this study aimed at evaluating the mechanical properties of some commercial restorative ion-releasing “bioactive...
emphasizing their pivotal contributions to mechanical properties. Our comprehensive review reveals a wealth of bio-inspired designs that have already made substantial inroads in mechanical engineering. From avian-inspired lightweight yet robust materials to hydrodynamically optimized forms borrowed from marine...
Elastic properties of classical bulk materials can hardly be changed or adjusted in operando, while such tunable elasticity is highly desired for robots and smart machinery. Although possible in reconfigurable metamaterials, continuous tunability in existing designs is plagued by issues such as structural...
UNIT I FLUID PROPERTIES AND FLOW CHARACTERISTICS 8 Units and dimensions- Properties of fluids- mass density, specific weight, specific volume, specific gravity, viscosity, compressibility, vapor pressure, capillarity and surface tension. Flow characteristics – concept of control volume - application of ...
urease is mainly used in the determination of urea in biological fluids. In this study, the artificially extracted plant enzyme was used, and urease was provided by Ruji biotechnology of Shanghai. Urease solution was prepared by dissolving urease in distilled water. In addition, cement was mixed...
The LDH particles were shaped as rectangular rods with a length of about 60 nm and width of around 20 nm. The films were evaluated for their physicochemical, topological, thermal, mechanical, water vapour, oxygen permeability and antimicrobial properties. Results indicated that active packaging with...
