The current study examines the feasibility of Ultrasint PP nat 01 polypropylene material in powder bed fusion through powder characterisation. The results obtained are also deemed to be pertinent when developing or validating analytical and numerical...

The spray drying of hard metal (WC-Co) powders is a critical step in the production of high-performance cutting and wear-resistant tools. Traditionally, organic solvents such as ethanol or acetone are employed in this process, despite posing substant...

The addition of hard particles such as borides to a ductile stainless steel matrix can be very efficient for improving mechanical properties. Powder metallurgy represents a suitable route for developing these material modifications, combining high re...

Electrostatic precipitators (ESPs) are widely applied to reduce particle concentrations. However, the performance of ESPs is impaired in the nanosized diameter range due to the difficulty in electrically charging these particles. The present work eva...

Thermal wick-debinding, commonly used in low-pressure injection molding, remains challenging due to complex interactions between binder transport, capillary forces, and thermal effects. This study presents a numerical simulation of binder removal kin...

Smokeless powders are a commonly used low explosive within the ammunition industry. Their ease of purchase has allowed criminals to use these products to build improvised explosive devices. Canines have become a vital tool in locating such improvised...

Particle deposition is a phenomenon that occurs in many natural and industrial systems. Nevertheless, the modelling and understanding of such processes are still quite a big challenge. This study uses a discrete phase model (DPM) to determine the dep...

The separation of particles smaller than 1 µm either by composition or by size is still a challenge. For the separation of SiO2 and SnO2, the creation of a selective separation feature and the specific adsorption of salts and surfactants were i...

The effect of induction heating on alumina ceramics and alumina ceramic composites based on α-Al2O3 nanopowders (additives: SiC, Si3N4, SiO2, ZrO2) has been examined. Various factors such as the structure, grain size, distribution of elements,...
