The heroes of our story were conceived in this oil refinery. The plastic in their bodies was formed by chemically bonding oil and gas molecules together to make monomers. In turn, these monomers were bonded into longpolymerchains to make plastic in the form of millions of pellets. Those were...
Microplastics also muck up the endocrine system, which regulates hundreds ofbodily functions, from mood to sleep to sex to metabolism. Hormones are literally the key to these functions: they're teeny molecules that float around in your blood until they find and bind with the receptor that matche...
The melting point of plastic depends on the polymer makeup of the plastic, and it can be low to high.The temperature at which a plastic melts is called the melt transition temperature because it is not defined. Plastics are polymers, or large molecules that are made up of many subunits. ...
These pills typically contain substances that bind to fat molecules, preventing their breakdown and subsequent absorption by the body. Fat blockers can be effective when used correctly and in conjunction with a low-fat diet. 4. Metabolism Boosters Metabolism boosters aim to increase the body’s ...
Polystyrene is a long chain hydrocarbon and is written as C8H8. The hydrogen bonds to the carbon in an alternating pattern via Van der Waals attractions (or the weak attraction of atoms and molecules of opposite charges). This weak force accounts for many of polystyrene's characteristics such ...
Hydrolysis initiation: Water molecules start breaking the ester bonds in PLA. Molecular weight reduction: The polymer chains break into smaller fragments. Microbial colonization: Microorganisms begin to colonize the PLA surface. Enzymatic degradation: Microbes secrete enzymes that further break down PLA. ...
Today I will introduce you what a polymer is. Academically, polymer ismade up of many molecules all strung together to form really long chains (and sometimes more complicated structures, too). Maybe the definition confuses many of us, but it does not really matter.Polymers are appeared in ...
Overall, however, linen is one of the least environmentally damaging textiles. Unlike synthetic textiles, natural fabrics like linen are biodegradable, which means that their constituent molecules reabsorb into the surrounding environment within a matter of years instead of centuries. Natural fibers also...
It is all about how different materials are put together and made up of atoms and molecules. Additionally, chemistry is how these materials act under different conditions. Slime is a non-Newtonian fluid. A non-Newtonian fluid is neither liquid nor a solid. It can be picked up like a solid...
The solvent also enters the binder and leaches from it the low molecular weight fraction of molecules, making the binder brittle [161]. So, being sensi- tive to moisture the solvent uptake and drying can be monitored with the NMR- MOUSE, and solvent-cleaning procedures can be optimized [...
