RFID chip next to a grain of rice. This chip contains a radio-frequency electromagnetic field coil that modulates an external magnetic field to transfer a coded identification number when queried by a reader device. This small type is incorporated in consumer products, and implanted in pets, for identification purposes. Radio-frequency identification ( RFID ) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects. The tags contain electronically stored information.
“An ounce of prevention is worth a pound of cure” – a common saying that is particularly true when it comes to peoples’ long-term health. The Seeker for this Challenge, UnitedHealthcare, seeks to promote healthier lifestyles and/or new approaches for managing widespread chronic conditions by taking advantage of two exciting dynamics in today’s marketplace – innovative consumer technologies and consumer-centric health solutions. Accordingly, they are seeking prototypes of novel combinations or modifications (“mods”) of existing, off-the-shelf consumer technology (including computer software and smartphone applications) that could be used to improve peoples’ health and quality of life. This is a Reduction-to-Practice Challenge that requires a written proposal and experimental proof-of-concept data (and/or prototype delivery). In the absence of a proven solution, however, the Seeker may make a partial award of up to $20,000 USD for a purely theoretical contribution.
Description chemCal is a basic chemistry concentration (molarity, moles per liter) and dilutions calculator for students of chemistry, biology, biochemistry, and biomedical sciences at school, college or university. The calculator is easy to use, just input the concentrations (Molar, mM etc.), molecular weights, percentages, and dilutions (liters) you wish to use, and you get the answer. The calculator can also easily and quickly convert between different unit values such as milli (m), micro (μ), nano (n), pico (p) and femto (f). * easy input

Sodium hydroxide , also known as lye or caustic soda , [ 2 ] [ 3 ] has the molecular formula Na OH and is a highly caustic metallic base . It is a white solid available in pellets, flakes, granules, and as a 50% saturated solution . [ citation needed ] Sodium hydroxide is soluble in water , ethanol and methanol . This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air . Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper , textiles , drinking water , soaps and detergents and as a drain cleaner .
Guanidinium chloride or guanidine hydrochloride , usually abbreviated GdmCl and sometimes GndCl or GuHCl, is the hydrochloride salt of guanidine . [ edit ] Structure Guanidinium chloride crystallizes in orthorhombic space group Pbca .
Sodium acetate , CH 3 COONa, also abbreviated Na O Ac , [ 1 ] also sodium ethanoate , is the sodium salt of acetic acid . This colourless salt has a wide range of uses. [ edit ] Applications [ edit ] Industrial Sodium acetate is used in the textile industry to neutralize sulfuric acid waste streams, and as a photoresist while using aniline dyes .
The chemical compound potassium chloride (KCl) is a metal halide salt composed of potassium and chlorine . In its pure state, it is odorless and has a white or colorless vitreous crystal appearance, with a crystal structure that cleaves easily in three directions. Potassium chloride crystals are face-centered cubic . Potassium chloride was historically known as " muriate of potash".
Sodium chloride , also known as salt , common salt , table salt or halite , is an ionic compound with the formula NaCl, representing equal proportions of sodium and chloride . Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms . As the major ingredient in edible salt , it is commonly used as a condiment and food preservative . [ edit ] Chemistry of solid and dissolved sodium chloride [ edit ] Solid sodium chloride
Virkon is a multi-purpose disinfectant . It contains oxone ( potassium peroxymonosulphate ), sodium dodecylbenzenesulfonate , sulphamic acid ; and inorganic buffers . It is typically used for cleaning up hazardous spills, disinfecting surfaces and soaking equipment. The solution is used in many areas, including hospitals , laboratories , nursing homes , funeral homes , medical , dental and veterinary facilities, and anywhere else where control of pathogens is required. [ 1 ] . Virkon has a wide spectrum of activity against viruses , some fungi , and bacteria . [ 2 ] However, it is less effective against spores and fungi than some alternative disinfectants. [ 3 ]
Small pellets of dry ice sublimating in air Crystal structure of dry ice Dry ice , sometimes referred to as " Cardice " or as " card ice " (chiefly British English ), is the solid form of carbon dioxide . It is used primarily as a cooling agent.
Sephadex is a trademark for cross-linked dextran gel used for gel filtration . It was launched by Pharmacia in 1959, after development work by Jerker Porath and Per Flodin . [ 1 ] [ 2 ] The name is derived from se paration Pha rmacia dex tran. It is normally manufactured in a bead form and most commonly used for gel filtration columns. By varying the degree of cross-linking, the fractionation properties of the gel can be altered.
Malachite green is an organic compound that is used as a dyestuff and has emerged as a controversial agent in aquaculture . Malachite green is traditionally used as a dye for materials such as silk , leather , and paper . Although called malachite green , the compound is not related to the mineral malachite — the name just comes from the similarity of color. [ edit ] Structures and properties Malachite green is classified in the dyestuff industry as a triarylmethane dye . Formally, Malachite green refers to the chloride salt [C 6 H 5 C(C 6 H 4 N(CH 3 ) 2 ) 2 ]Cl, although the term Malachite green is used loosely and often just refers to the colored cation .
