What are the Primary Conditions Affecting Surface Tension?

Posted by Art Gatenby on Sep 23, 2013 12:42:00 PM

One of the ways to describe surface tension in fluids is: the property of a liquid’s surface that resists force. It serves as a barrier to foreign materials and holds the liquid together. This ever-present property is caused by unbalanced forces on surface molecules that pull toward the main part of the liquid.

Moisture Content and Water Activity - What Are They?

Posted by Art Gatenby on May 30, 2013 1:23:00 PM

Many accessing our web site ask questions such as:

  • “How does water content affect water activity?”

  • "How is water activity different from water content?”

  • ”Can I convert from moisture to water activity?”

I previously commented on water activity and now hope to clarify the differences between water activity and moisture content. Given that both of these measurements deal with water connected to a material, we must first understand of water content in a product.

Advances In Sieves: Sieves Able to Strip Molecules From Fluids

Posted by Art Gatenby on Nov 19, 2012 2:32:00 PM

Sieves make understanding the world around us not just possible, but also easier.

And with the advancement of sieves, not only are we able to separate dry particle, but also sift molecules from fluid as well. With molecular sieves developed by MIT, we can now strip a molecule’s individual parts gives us a better understanding of how things come together and work, such as diseases or even DNA.
