Finally: After 250 years, a solution to this intriguing and important phenomena of osmosis has been found. Many other solutions have been proposed, no others fully explain the process and the many applications. This book introduces a new understanding of osmosis, solids, liquids, and vapor pressure and more
We were intrigued by the photos and blowups in John Clancy’s excellent book “The Human Body-Close Up” we browsed through the book from the back and were amazed at the detailed photos of the human body and its various parts. We were surprised when we approached the front of the book to find a blowup …. Read More
Quora digest posed the question “What is the difference between Diffusion and Osmosis?” We reviewed Guyton’s Textbook of Medical Physiology. He notes three modes for transport of ions and molecules through a cell membrane: diffusion, osmosis, and active transport. We have previously looked at active transport. The active transport models were developed to explain movement …. Read More
The osmosis experiment demonstrated that water flows uphill through a membrane from the pure water side into the wine. A large pressure applied to the wine stopped the flow of water into the wine. Later experiments showed that a sugar water solution could replace the wine. This led to Van’t Hoff’s theory for osmosis that …. Read More
HTMD Engineering was given the opportunity to design and build a cold storage facility for DeKalb Genetics for their hybrid seed corn. The industry standard design conditions of 50°F and 50% relative humidity were selected, and we chose to insulate the facility with a closed cell spray on insulation which provided both good thermal insulation ….

Our previous blogs about trees, “My Tree Leaks”, “Maple Syrup” were based on our theory of osmosis, “Osmosis: The Molecular Theory”, 2013” and measurements from our own sugar maple tree. We tapped the tree by drilling a 2 ½” deep hole through the bark and inserting a 3/8” pipe with a pressure gauge as shown …. Read More
Seeds are living organisms. They breathe and exchange heat and moisture with their environment. With warm temperatures and enough moisture, seeds will germinate. At low temperature and dry conditions, seeds will hibernate. World seed organizations support long term storage facilities. Stored seeds will be used for recovery from a catastrophe. The Svalbard Global Seed Vault …. Read More
Maple Tree Details Our previous blogs about trees, “My Tree Leaks”, “Maple Syrup” were based on our theory of osmosis, “Osmosis: The Molecular Theory”, 2013” and measurements from our own sugar maple tree. We tapped the tree by drilling a 2 ½” deep hole through the bark and inserting a 3/8” pipe with a pressure …. Read More
My Tree Leaks This year, I discovered that my maple tree leaks. A wet spot appeared on the sidewalk near the base of the tree. The weather was below freezing at night and warmer in the day. The tree trunk remained below freezing during the day. As noted in the maple syrup discussion, we proposed: …. Read More
During my college days, it was a well-known “fact” that I could learn by placing a book under my pillow at night. Information from the text would be transferred to my brain by osmosis. It never worked for me. And, it was terribly uncomfortable with some larger texts. I have had success with sleep time …. Read More
We have proposed that osmosis is directly related to vapor pressure and that free vapor molecules exist in liquids and solids. The quantity of these free molecules is in proportion to the vapor pressure value. The net flow of free molecules through a porous membrane is the called osmosis. Flow through porous membranes may also …. Read More
