Solid neoplasms are cancerous masses that can be benign, malignant, or pre-malignant. They can be caused by genetic mutations or overgrowth of normal tissue cells and can affect any part of the body. Treatment options include surgery, radiation, and chemotherapy. A solid neoplasm is a special type of cancer that can appear anywhere in the […]
Solid shafts convert circular power from a driveshaft into linear motion to propel a vehicle. They are commonly found in rear-wheel drive cars and trucks, while independent front axles provide a smoother ride. Swapping a solid axle for a split axle involves removing suspension and steering components and welding leaf spring brackets in place. The […]
Solid waste management is the process of managing garbage, including municipal waste collection, recycling programs, landfills, and incineration. It has been a problem since humans settled in communities, generating more waste than ever before. The first methods of waste management were digging holes and dumping garbage, creating a record of historical daily life. Today, solid […]
Solid Freeform Fabrication (SFF) is a process that uses computer files and controlled equipment to build three-dimensional components layer by layer. Four common types of SFF include selective laser sintering, laminated object manufacturing, stereolithography, and fused deposition modeling. SFF is used in research and development, manufacturing prototypes and custom components, and has military applications. A […]
Solid tires are non-pneumatic and mostly used for light commercial or industrial applications. They are resistant to wear and tear, puncture damage, and can handle heavy loads. They can be made of solid rubber or molded from plastic compounds. They are not recommended for fast vehicles but are suitable for slow-moving industrial machines. Solid tires […]
Aerogels are created by supercritical drying of a gel, preventing capillary action. Airgel is 99.8% air, with a density of 3mg/cc. It has many uses, including as a thermal insulator and in supercapacitors. Carbon nanofoam is the most common solid. The most common solids are aerogels, created by subjecting a conventional gel to supercritical drying. […]
Solid state memory devices, such as SSDs and flash memory cards, store data without moving parts. They are used in many electronic devices and can be expanded for more storage. Flash drives and memory cards are portable and easy to use. Some devices have built-in solid-state drives to reduce wear on internal parts. Prices are […]
Sound waves travel faster through solids and liquids than through air, with speeds of up to 3.7 miles per second in steel and 0.93 miles per second in seawater. Sound travels slower in air, at about 0.21 miles per second. Sound waves can travel faster through solids than through air, in some cases more than […]
Solid-state reactions are chemical reactions that occur without the use of solvents. They are cost-effective, environmentally friendly, and produce more product than normal reactions. Solid-state reactions can occur through oven, fusion, or gas techniques. However, they may not always result in a uniform substance and are not suitable for solvent-requiring reactions. A solid-state reaction, also […]
Filled cable is a wire used in telecommunications that is filled with a non-hygroscopic substance to prevent moisture from entering the cable jacket. It is useful for areas subject to high humidity and commonly uses a petroleum-based gelatinous material called “Icky-pic”. A filled cable is a wire used in telecommunications. It is filled with a […]
Less than 5% of the universe is solid matter, with 68% dark energy and 27% dark matter. Dark energy expands the universe, while dark matter’s gravity can be measured. The sun makes up 99% of the solar system, and it would take 800 years to reach Pluto. The vast majority of the universe is made […]
Solid Phase Extraction (SPE) separates solid and liquid substances in a chemical solution by passing the sample through a column filled with an absorbent. The process concentrates and purifies samples for further study and can be performed on a large scale. SPE is preferable to liquid-liquid extraction as it takes less time and can be […]
Glass is a solid, not a liquid, despite old myths about church windows and a misreading of a physics book. It is an amorphous solid, which means it does not crystallize like most other solids. Glass can have different properties depending on how it is cooled and the presence of impurities. The labels “solid” and […]
Crystalline solids have atoms, ions or molecules arranged in a repeating pattern called a lattice, giving them physical characteristics that vary. They are resistant to compression and have enormous strength. There are seven basic shapes, with 14 possible lattices affecting physical properties such as melting point and light refraction. Diamond is the hardest substance due […]
Sulfuric acid can exist as a solid, liquid, or gas depending on temperature. Solid sulfuric acid can be created by cooling it below 50°F, but dilution with water affects the freezing point. It is important to store sulfuric acid at the correct temperature to avoid unexpected changes in volume. Like all matter, sulfuric acid can […]
Amorphous solids lack a lattice or crystalline structure and make up only 10% of solids. Glass is the best-known example. Molecules in solids are bound together with no freedom of movement, but still wobble in their bonds. Crystalline solids have an orderly pattern, while amorphous solids may have a repeating pattern for small portions. Amorphous […]
Solid wood office furniture is a great choice for a professional and durable office space. It is sturdy, long-lasting, and adds a subtle edge to the space. However, it is heavier and more expensive than other materials, so consider the advantages and disadvantages before purchasing. Every professional should want their office space to look its […]
Specialty advertising uses free promotional products to advertise a company’s presence to its target market. Common items include pens, calendars, keychains, coffee mugs, and clothing. These items can be personalized with a company’s logo and contact information. Custom pens are the cheapest option, while clothing is often given away as prizes during customer appreciation events. […]
Advertising industry analysis involves studying data on advertising companies’ performance and activities to make budget decisions and marketing plans. The analysis covers a specific period, region, or sector and includes information on advertising spending and trends across different mediums. Businesses use industry data to compare costs, predict economic trends, and reduce operating costs. Advertising industry […]
Economic freedom allows individuals to control their financial well-being, including managing assets, choosing work, seeking fair compensation, and consuming resources. Governments may regulate economic freedom to maintain order and protect citizens’ rights. Laws and regulations prevent actions that interfere with economic freedom, such as theft. Economic freedom is a concept that proclaims the inherent right […]
