Smelting separates usable metals from mixed deposits. The process involves heating the material with an agent to force precipitation of the desired mineral. Density changes allow for removal of desirable ore. Industrial metal production weighs the value of ore against the cost of mining. Smelting is a process of extracting usable ore from mixed deposits […]
Fusion welding joins two pieces of metal by melting them with a filler metal and flux. Types include arc, electric resistance, oxy-fuel, thermite, and laser beam welding. Each has unique advantages and limitations. Fusion welding is the process used in metalworking to join or fuse two pieces of metal causing the metal to reach its […]
Electron beam fusion (EBM) is a rapid manufacturing method that uses an electron beam in a vacuum to fuse layers of powder to create complex parts with high density and desirable physical characteristics. EBM is suitable for use with metals, ceramics, and metal-ceramic composites and is often used to produce high-performance parts such as turbine […]
Hot melting, also known as heat welding or plastic welding, uses heat to join materials together. The process involves heating the materials until they soften and then pressing them together to form a bond. This method creates a stronger bond than adhesives and is used to join plastic, glass, and metal. Hot melting is also […]
Fusion splicing joins two optical fibers end-to-end by heating and fusing them together. Special tools and methods are used to avoid damage, and the fibers are stripped, cut, inspected, aligned, and fused together. Protection is then added to the splice using a chemical protectant or fiber optic splice protector. Fusion splicing is a term that […]
The process of fusion is used in industrial applications, manufacturing processes, and hobbies. Different melting methods are used, such as welding, glass fusing, and melting fabrics and plastics. Metal casting has many industrial and manufacturing applications. Laser melting is a new technique used to repair surfaces or provide coatings on surfaces. Fusion is a joining […]
Fusion cooking combines foods and cooking styles from different sources to create new dishes and flavor combinations. It is divided into three categories: combining regional tastes, adding unique ingredients to traditional dishes, and replacing ingredients with those from a different cultural cooking style. Wolfgang Puck is credited with introducing fusion cuisine in the 1970s at […]
Melt strength is important for plastics in a molten state during processing. Additives can alter melt strength and other properties. Material testing can uncover safety issues. Plastics with high melt resistance are preferred for extrusion molding. Companies are developing products to address concerns about durability, safety, and pollution. Melt strength is a measure of how […]
Magnetic confinement fusion involves suspending plasma in a magnetic field and raising its temperature and pressure to produce nuclear fusion. Inertial confinement fusion is another approach. Fusion power is yet to be successfully generated, but the International Thermonuclear Experimental Reactor is pursuing magnetic confinement fusion. The core of a tokamak reactor must be heated to […]
Yves Rossy, also known as Fusion Man, built and flew the first jet-powered wing in 2006. The wings were made of carbon fiber and powered by four small kerosene Jet-Cat jet engines. Rossy used a Pilatus PC-6 propeller plane as the takeoff point and flew for 6 minutes and 30 seconds, reaching speeds of 160 […]
Inertial confinement fusion uses lasers to rapidly compress and heat a small pellet containing deuterium and tritium to induce nuclear fusion. The goal is to achieve ignition and produce more energy than consumed, but technical challenges remain. A new approach called rapid ignition has been proposed but not yet tested. Inertial confinement fusion (ICF) is […]
Nuclear reactions release energy from atomic nucleus bonds. Fusion combines atomic nuclei for lighter elements, while fission splits heavier ones. Nuclear energy is difficult to harness due to purification and temperature requirements. Fusion requires high energy and containment. Fission has radioactive byproducts and safety concerns, but advances have made reactors safer. The US government is […]
The heat of fusion is the energy needed to transform a solid into a liquid. The temperature remains constant during this process, and the energy is stored as potential energy. Different substances require different amounts of heat of fusion, depending on molecular bonds. The heat of fusion, also called the enthalpy of fusion, is the […]
Cold fusion is a low-temperature nuclear fusion reaction that uses deuterium as a potential source of energy. However, there is currently no consistent technique for generating a cold fusion reaction that produces more energy than is needed to sustain the reaction. The US Department of Energy recommends no additional funding for cold fusion research, as […]
Fusion energy is the extraction of energy from the fusion of light elements and isotopes such as hydrogen, deuterium, tritium, and helium. It contrasts with fission, which breaks down heavy nuclei. Fusion powers the Sun, and scientists hope to harness it for human needs. H-bombs are fusion-based and more efficient than fission-based A-bombs. Two approaches […]
Nuclear fusion is the process of combining atoms to form a heavier nucleus, releasing or absorbing energy. It is different from nuclear fission, which involves splitting atoms. Fusion is a source of energy and is how stars generate energy. The challenge is bringing atoms with the same charge close enough to fuse, which is achieved […]
Multi-sensor data fusion combines data from multiple sensors to create more accurate datasets, with applications in meteorology, environmental analysis, transportation management, and target tracking. It relies on sensor technology, mathematical processes, and data integration, and mimics human perception. Low-level data fusion combines raw data to create more specific and synthetic datasets. Multi-sensor data fusion is […]
Subtalar arthrodesis is a surgical treatment for ankle pain when other methods fail. The procedure involves fusing the subtalar joint, limiting ankle movement and causing potential discomfort. Patients should ask questions and seek an experienced surgeon. Subtalar arthrodesis is a surgical treatment for intractable ankle pain, which involves fusion of the subtalar joint within the […]
Fusion energy is the extraction of energy from the bonds between particles in the nuclei of atoms by fusing those nuclei together. It contrasts with fission, which is easier and better developed. Scientists hope to develop a fusion power plant before 2050. H-bombs are fusion-based and have higher yields than A-bombs. Fusion energy powers the […]
