In the past few years, scientists have also discovered magnetic polymers, or plastic magnets. Some of these are flexible and moldable. However, some work only at extremely low temperatures, and others pick up only very lightweight materials, like iron filings. Contents Making Magnets: The ...
The structure of secondary cell wall polymers: How Gram-positive bacteria stick their cell walls together. Microbiology. 2005; 151 :643–651. doi:10.1099/mic.0.27749-0 .Schäffer C, Messner P. 2005. The structure of secondary cell wall polymers: how Gram-positive bacteria stick their cell ...
It is seen that the integration algorithm requires initial positions and momenta. This, indeed, is an obvious consequence of the EoM written in the Hamiltonian formalism, which are first-order differential equations in\(\pmb {R}\)and\(\pmb {p}\). Initial positions can be set in many diffe...
Polymer chemistry studies the synthesis, properties, and applications of polymers. Polymers are large molecules of repeating subunits widely used in industries such as plastics, textiles, and biomedicine. Biodegradable polymers: synthesis and environmental impact Polymers in tissue engineering and regenerative...
Gordon incorporated SEL into a lesson on polymers. The students made sculptures of colorful polymer clay to reflect their experiences over break. The next day, Ms. Gordon had them look at each other’s finished sculptures silently so they could notice how they experienced each other’s ...
Wires can connect two terminals together, or they can connect dozens. When a wire splits into two directions, it creates ajunction. We represent junctions on schematics withnodes, little dots placed at the intersection of the wires. Nodes give us a way to say that "wires crossing this junct...
The unbalanced pressure from the surrounding depletants pushes the colloidal particles further together, resulting in an attractive interaction between them (Fig. 8). The depletion force depends on the size (for polymers on the radius of gyration) and concentration of the depletants. For distances ...
When you combine polyvinyl acetate (found in clear glue) with borate ions (from saline solution or borax powder), it causes the molecules to link together. This chemical reaction creates polymers, which give slime its stretchy, gooey texture. It’s hands-on chemistry perfect for kids! 🔎 ...
Applying pre-ceramic polymers to small cracks Using small mechanical plugs made of carbon-silicone carbides to repair damage up to 6 inches in diameter These ideas were tested aboard the shuttle Discovery in June 2005. History of the Space Shuttle The Enterprise separates from a Boeing 747 to ...
Spheroids made by culturing in suspensions or low attachment plates and cell sheets made by culturing on thermo-responsive polymers have also been applied to 3D cultures. Using the EHT system and iPSC-CMs, models for chronic non-hereditary cardiomyopathy, such as heart failure, have been ...
