Semi-synthetic Polymers, chemically modified natural polymers Cellulose nitrate is derived from the cellulose that makes up plant cell walls; it is so combustible it can be used in place of gunpowder. Rayon fiber, or cellulose acetate, is used to make a variety of yarns and fabrics. Plastics...
Synthetic fibresare man-made fibres. The raw material used for making these fibres is petroleum. Hence another name for these fibres is‘petrochemicals’. Small units called‘polymers’make up these fibres.‘Monomer’is the individual unit that makes up each polymer. ...
As such, due to unacceptable toxicities, the first generation of oxygen-carriers has been withdrawn from the market. Being hemoglobin (Hb) the main component of RBCs, a lot of effort is being devoted in assembling semi-synthetic RBCS utilizing Hb as the oxygen-carrier component, the so-called...
What is the cell wall made of? The structure of cell walls is not similar in all species; it depends on the developmental stage and cell type. The plant’s primary cell wall consists of pectin, cellulose, and hemicellulose along with other anchored or embedded polymers such as suberin, lig...
after freeze-drying and reconstitution. This can be attributed to the stabilization of the polyethylene glycol (PEG) chains to the system during the freeze-drying process. Further studies using other polymers, besides PEG, to achieve the same stabilization effect...
The foundations of materials engineering include the fields of metallurgy A contemporary automobile is comprised of a wide range of materials, from the traditional to the advanced. Science has introduced the manufacturing of parts such as moldable polymers. ...
摘要: The relative merits of a technique depend often on the specificity of the field where it is applied and on the available alternatives. In this perspective it is not surprising that in polymer crystallography electron diffraction has been comparatively more fruitful than for low-molecular weight...
The trend of employing machine learning methods has been increasing to develop promising biocatalysts. Leveraging the experimental findings and simulation data, these methods facilitate enzyme engineering and even the design of new-to-nature enzymes. This review focuses on the application of machine learn...
Studied sludge samples are composed of major goethite and quartz; less clay minerals; and minor magnetite, hematite, clinochlore and todorokite. They have quite similar qualitative, but different semi-quantitative compositions. There are similar particle
