#NATURE ABHORS A VACUUM HOW TO#

You will notice a small plate around the brush. To check out the vacuum cleaner belt, you will want to flip the vacuum on its front so that the brush is facing you. The most common problem is a belt malfunction. There are actually not a lot of vacuum parts which malfunction. In order to repair the problem, you first need to determine what is wrong with your vacuum cleaner. For instance, if you have a Hoover vacuum, you can learn specifically about Hoover parts and how they work. You can find a lot of great information by checking out the website of the manufacturer who made your vacuum. However, did you know that it is quite easy to repair a vacuum cleaner? What do you do if your vacuum is not working correctly? Many people will simply throw away their vacuum and purchase a new one. It always seems that your vacuum will malfunction right before company is set to arrive. “This is a grand research objective across many scientific disciplines, and our work represents a new tool in that quest,” he said.Vacuum Cleaner Repair in San Jose Vacuum Cleaner Repair in San Jose, NM

Thus we are making a synthetic enzyme-like pocket.”Īshbaugh said the study helps towards understanding how to create synthetic materials that act like biological materials. “Our work shows that we can control the strength of the ball and socket interaction by changing how much water wants to go into the pocket. Enzymes have pockets on their surfaces that bind to ligands, or molecules, on which they work to catalyze reactions. He said enzymes work on a similar principal. He said the paper shows that by using simple design criteria, “we can make it so that water does not even want to sit it the socket, making it easier for the ball and socket to get together.” “To be able to get the ball and socket together, we have to get the solvent, or water, out of the socket to seat the ball.” “This could potentially impact the design of ‘self-healing’ materials - soft materials that fix themselves following damage,” said Hank Ashbaugh, a co-author of the paper and a chemical engineering professor at Tulane.Īshbaugh’s fellow authors of the study, titled “Spontaneous drying of non-polar deep-cavity cavitand pockets in aqueous solution,” are chemistry Professor Bruce Gibb along with Dor Ben-Amotz, a professor of physical chemistry at Purdue University.Īshbaugh likened the cavitand to a socket and anything that binds to it as a ball. The study, which was featured on the cover of Nature Chemistry, provides new insights on how to modify the stickiness of these molecular building blocks, allowing engineers to build materials, like gels, from the bottom-up.

“This is a grand research objective across many scientific disciplines, and our work represents a new tool in that quest.” In their study, published in Nature Chemistry, the researchers showed that it is possible that water may refuse to fill a class of bowl-shaped molecules called cavitands - depending on the placement of oily groups around the rim of the molecule’s bowl when placed in aqueous solution. The phrase expresses the idea that unfilled spaces go against the laws of nature and physics and that every space needs to be filled with something.

Tulane chemistry Professor Bruce Gibb, left, and chemical engineering Professor Hank Ashbaugh teamed up on a study that has been published in Nature Chemistry.
