Other materials such as small organic molecule do not form lattices. Charge flows within the molecule and also hops between molecules. Whilst this might limit conductivity to some extent these materials offer more opportunities within an electronic device that traditional inorganic semiconductor materials ...
Breaking molecules apart and putting molecules together is what enzymes do, and there is a specific enzyme for each chemical reaction needed to make the cell work properly. Maltose is made of two glucose molecules bonded together (1). The maltase enzyme is a protein that is perfectly shaped ...
Another theory of how glues work suggests the adhesive can diffuse into the surface and vice-versa, with molecules swapping over at the join and mingling together. This is called the diffusion theory.How do Post-it® notes work?So what about that little Post-it® note stuck to your ...
which researchers have accomplished. Next, scientists must be able to turn on specific genes within the stem cells so that the stem cells will differentiate into any cell they wish. But scientists have not learned how to do this yet; so, studying stem cell differentiation is an active area...
Second, lymphocyte-activation gene 3 (LAG3) binding to MHC class II molecules inhibits DC maturation and function. Several complicating issues should be considered when evaluating the importance of these varied mechanisms. First, TReg-cell function is considered contact-dependent yet it is not clear...
In reality, the molecules in liquid crystals can form themselves into a number of different phases, and because they're not pointing randomly in all directions, they're generally anisotropic (they do different things to light when it hits them from different directions). In some thermochromic ...
consider it a miracle but we’d like to describe it as physics in action. Remember we mentioned earlier how motors and propellers work together. Well, they’re responsible for drones flying. The motors spin the propellers while the latter pushes against the air molecules to get the drone ...
When the electric discharge is very strong, collisions of high velocity electrons with molecules of gas result in no loss in momentum, and electron avalanching occurs. When a plastic part is placed in the discharge path, the electrons generated in the discharge impact the surface with energies ...

Each molecule of adenylyl cyclase then triggers the formation of many molecules of cAMP. Further amplification occurs as protein kinases, once activated by cAMP, can catalyze many reactions. In this way, a small amount of hormone can trigger the formation of a large amount of cellular product....
