Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH 2 =CHC(O)NH 2. It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH 2 ).
Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1]
Transpirational cooling is the cooling provided as plants transpire water. Excess heat generated from solar radiation is damaging to plant cells and thermal injury occurs during drought or when there is rapid transpiration which produces wilting. [1] Green vegetation contributes to moderating climate by being cooler than adjacent bare earth or ...
The CPSC recorded nearly 7,000 water bead-related ingestion injuries in emergency rooms between 2018 and 2022. The agency issued warnings this week about two products with toxicity risk, urging ...
The water cycle (or hydrologic cycle or hydrological cycle), is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time. However, the partitioning of the water into the major reservoirs of ice, fresh water, salt water and ...
The clouds in this image of the Amazon Rainforest are a result of evapotranspiration. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. It is a passive process that requires no energy expense by the plant. [1]
Potassium polyacrylate is a potassium salt of polyacrylic acid with the chemical formula [−CH 2 −CH (CO 2 K)−] n. As a type of superabsorbent polymer, it can absorb hundreds of times its original weight in purified water. Different from sodium polyacrylate, potassium polyacrylate can be used as water retaining agent in agriculture and won ...
In a pinch, you can make popsicles with just one fruit. Let's use blueberries, for example, because they're safe for dogs (and many other animal species) to eat. Simply mash up some blueberries or ...
