The tie molecules are embedded in the crystallites and transverse amorphous regions, acting as mechanical links between the crystalline domains, and play a decisive role in the resistance to fibril failure and overall mechanical properties when subjected to stress.
Sustainable Energy means energy sources that will allow the Earth to sustain balanced, healthy ecosystem s and human life. Fossil fuels â coal, oil and gas â are not sustainable energy sources because when we burn. them to create energy, they create massive levels of greenhouse gases, which result in human. impact on the global climate.
