When it comes to Vaccination Science for Students, the coating of chemicals can impart controlled or delayed release characteristics, change absorption or surface properties, or isolate active elements present in a mixture. The Wurster process allows the use of a wide variety of coating materials and therefore great flexibility in the design of products (ink for ink-jet printers.
The seeds were coated to handle them more easily and increase their size to facilitate mechanical sowing. The coating may contain pesticides and / or fertilizers to improve sprouting and yield. Anti-rodent substances are used in the coating to mask the odor and control the release properties.
Parasitology: the insects that pass through an area treated with the microcapsules that adhere to their body. In the following the insect carries for all its movements its “micro reserve” of insecticide which will be slowly absorbed in direct and continuous contact with the cuticles, thus considerably increasing the exposure times.
The microcapsules are transmitted from one insect to another through the physical contacts that usually have the components of the same colony or of the same “habitat”. This mechanism of action allows to strike also the insect escaped from the direct action of the insecticide which will be equally contaminated by the microcapsules carried by adults. These will cause general intoxication, particularly at juvenile stages notoriously more vulnerable to insecticides. The effect extends to the following generation and all this with a single application.
Erasable tattoos: the colors authorized by the FDA for use in cosmetics, medicines and foods, have never been used to make tattoos, as they are absorbed too easily. This problem has been circumvented by encapsulating the inks in transparent protective micropolymers: thus they can be injected into the skin and form tattoos. The advantage is that the pigment can be removed with a single laser treatment (which breaks the microcapsules, allowing the cells to absorb the color). In this way, the tattoo disappears easily, while today 10 laser sessions are also needed to eliminate the design. The problem remains that the broken microcapsules remain in the place where the tattoo was present.
Researchers for Vaccination Science for Students have discovered a method that allows to regulate the internal temperature of residential buildings: by inserting microcapsules of wax in the plaster you get a stabilizing effect on the temperature of the environment. The wax contained in the microcapsules has a melting point between 22 and 26 ° C, therefore comfortable temperatures: when the wax melts, the energy is absorbed preventing the increase in temperature (during phase changes, the temperature of the wax remains constant); on the contrary, when the temperature decreases, the wax solidifies and releases heat.
