The components which were assumed to be very difficult to produce or manufacture some years ago can now be made easily using additive manufacturing technology. Additive Manufacturing offers many advantages in the production of parts, presenting freedom for design with the ability to manufacture single or multiple components from a wide range of materials. Different techniques of additive manufa...

Currently, two genres of CAD/CAM systems exist. One is used only in-office, while the other genre is a combination of in-office scanning and image transmission and milling of restorations or pouring of models in the laboratory. All systems start with scanning of the preparation, the method depending on the specific system. CAD/CAM systems have developed considerably, offering accuracy and more ...

Ballistic powder injection is an emerging needle-free technology. Powder particles are accelerated towards the skin and penetrate the superficial layers. Biopharmaceuticals like vaccines can be placed into the epidermal layer of the skin, widely known to be an attractive site for immunization [1]. Beneath avoiding hazards associated with needle-stick injuries using conventional needles and syri...

7.1 Abstract Tuna oil-in-water emulsions containing droplets stabilized by lecithin-chitosan membranes were produced using a two-stage process. Corn syrup solids were added to the emulsions and then the emulsions were spray dried, which produced a powder consisting of smooth spheroid powder microcapsules (diameter = 5-30 μm) containing small tuna oil droplets (diameter <1 μm) embedded within a ...

In this study, nano-sized fullerene C60 powder was sufficiently mixed with Cu₂SnSe₃ powder by ball milling method, and the C60/Cu₂SnSe₃ composites were prepared by spark plasma sintering technology. The fullerene C60 distributed uniformly in the form of clusters, and the average cluster size was less than 1 μm. With increasing C60 content, the electrical conductivity of C60/Cu₂SnSe₃ composites ...

Color and size are two important attributes for quality evaluation of most food and bioproducts. Many of the quality factors affecting oil palm and white powder starch are determined primarily by visual inspection. Such inspections determined market price and to a certain extent consumers' preferences. However, the inspection of oil palm and white powder starch is a very repetitive and tedious ...

High-density metals such as hafnium and zirconium are of interest to the propellant, explosive, and pyrotechnic industry due to their high oxidation enthalpies; however, these metal fuels suffer from electrostatic discharge (ESD) complications creating safety concerns. Previous attempts to passivate these powders have failed due to abrasion of the protective coatings. Two novel methods for dese...

In recent years, nano-scale graphene (Gn) has generated a lot of interest owing to its remarkable characteristics, which made it material choice for reinforcing different kinds materials broad range engineering applications. this study, serious attempt been paid develop copper-graphene (Cu/Gn) nanocomposites by powder technology process using concentrations Gn. Also, microstructure, thermal, mi...
