Engineered stone is a man-made material used in kitchen and bathroom décor as an alternative to granite. It is made by crushing natural stone, adding additives and colorants, and compacting it with resin. The final product is more uniform, non-porous, and easier to clean than natural stone. It is commonly used as a replacement for […]
Artificial elevators pump liquid from a source well or container for industrial and scientific purposes. Hydraulic, gas, beam, and electric submersible pumps are commonly used depending on the depth and pressure of the well. The industry is constantly evolving to create new and better pumps. An artificial elevator is a device that pumps a liquid […]
The FDA has classified five artificial sweeteners as safe: saccharin, aspartame, sucralose, acesulfame K, and neotame. However, studies continue on their long-term health effects, and some evidence suggests possible dangers. Side effects of each sweetener are discussed, with concerns ranging from sulfonamides in saccharin to methylene chloride in acesulfame K. Artificial sweeteners are completely synthetic […]
The FDA has classified five artificial sweeteners as safe, but studies continue on their long-term health effects. Some evidence suggests possible dangers, and side effects are still being studied. The oldest, saccharin, has undergone over 30 human studies and is deemed safe, but some believe it could pose risks. Aspartame is listed in over 6,000 […]
Artificial sweeteners replace sugar with fewer calories and are suitable for people with dietary restrictions. Aspartame is the most used sweetener, while sucralose is challenging it due to its lower price. The global market for artificial sweeteners is driven by economics, with manufacturers pushing their products for higher profit margins. An artificial sweetener replaces the […]
Artificial blood carries oxygen throughout the body but cannot replace real blood. Hemoglobin-based oxygen carriers and perfluorocarbons are the two main types, with different methods of carrying oxygen. Artificial blood is useful in emergencies and has a longer shelf life than real blood. Artificial blood, also known as oxygen therapy, works by carrying oxygen throughout […]
Saccharin, aspartame, and sucralose are the most commonly used artificial sweeteners in the US. They differ in composition and usage. Saccharin is the oldest and is used in sodas, candies, and toothpaste. Aspartame is 180 times sweeter than sugar but has a slower onset and longer taste life. Sucralose is heat stable and made with […]
Artificial stone includes synthetic gemstones, stone veneer, concrete compounds, and cast stone. Coade stone, a ceramic compound, was created in the 18th century and is revered for its erosion resistance. Man-made gems are used for jewelry and industrial purposes. Concrete is a primary ingredient in cast stone, which can be stained or painted to mimic […]
Artificial insemination is a medical process to help women get pregnant by inserting sperm into the cervix or uterus. It is less expensive than IVF and can be used by lesbian couples or single women. Success rates depend on the woman’s age and health. Artificial insemination is a medical process that is used to help […]
Artificial hearts have been developed to replace weak hearts, but they don’t last forever. Ventricular assist devices and left ventricular assist devices are also used. The first implant was performed on a dog in 1957, and two artificial hearts, the Jarviks and Abiocors, were developed in the 1980s. Dr. Alain Carpentier of France created an […]
Artificial photosynthesis replicates the process of photosynthesis to harness the sun’s energy in an environmentally friendly way. Research has yielded two results: photoelectrochemical cells and dye-sensitized solar cells. Both aim to achieve artificial photosynthetic energy that can be stored for later use. The most effective catalysts are cobalt and rhodium. Gratzel cells are the cheapest […]
Artificial architecture uses computational methodologies and algorithms to create natural-looking architectural forms. It allows for the creation of unique structures using scripting languages and generative processes. The computer is a collaborative partner, allowing architects to create extraordinary structures that incorporate creative computational design. The designer defines the framework, and the computer creates its own morphologies […]
Artificial gravity replicates Earth’s gravity in space, making people more comfortable and reducing problems associated with weightlessness. Methods include rotation, mass, magnetism, and linear acceleration. It is important for long-term space settlements and is a major obstacle to space travel. Science fiction often incorporates artificial gravity due to filming ease. Artificial gravity is a replica […]
Artificial eyes come in two types: ocular and vision prostheses. Ocular prostheses are for cosmetic purposes only, while vision prostheses provide visual input by stimulating the optic nerve. Researchers are constantly refining the science behind artificial eyes, and fitting must be carefully done to avoid injury. An artificial eye is a prosthesis that is used […]
Artificial blood is used in medical procedures and to treat certain conditions. There are two main categories: oxygen therapy and volume expanders. Perfluorocarbons and hemoglobin are used to transport oxygen. Hemoglobin-based artificial blood is most pursued by the US military. Artificial blood is a basic filler for the human cardiovascular system used in certain medical […]
Artificial snow slopes are found in resort towns in temperate or warm zones, produced using snow cannons that shoot tiny ice balls into nebulized liquid water. Seed materials such as magnesium ions, calcium, or clay particles are used, and the most realistic-looking artificial snow is made from a freeze-dried protein powder called Snomax®. The floor […]
Researchers at the University of Texas and Pusan National University created fuel-powered artificial muscles using carbon nanotube electrodes and nanoparticle catalysts. The muscles could contract with 500 times the stress-generating capacity of human muscle and could potentially be integrated into human subjects. The fuel-powered artificial muscles refer to an advance in robotics and engineering by […]
Yeast artificial chromosomes (YACs) are self-replicating chromosomes used in genetic research to clone large amounts of genetic material for sequencing and mapping. Technicians break up DNA and extract the desired fragment, which is inserted into a vector with telomeres, centromeres, and replication origin sequences. YACs can be ordered from scientific suppliers or created in-house. YACs […]
Artificial respiration can be delivered through natural methods such as mouth-to-mouth resuscitation or through mechanical means like intubation. It is vital to supply oxygen to prevent brain cell deterioration, and can be used to maintain organ function in brain dead organ donors. Mechanical respiration can be necessary for premature infants or patients on anesthesia, but […]
Bacterial artificial chromosomes (BACs) are plasmid-based vectors used by microbiologists to insert genes into bacteria. BACs can carry significantly more genetic material than other vectors, allowing for the study of larger genes. BACs are inserted into bacteria using electroporation and can be used to clone large quantities of genetic sequences for study. They have accelerated […]
