Osmotic Pressure

I must have been feeling “osmotic pressure” since I missed posting for the last month. We all know that that excuse is as lame as learning by osmosis from a book under your pillow. Now, let’s review osmotic pressure. Osmotic pressure is the minimum pressure required to stop solvent from flowing through a membrane into ….  Read More

Pressure Reduced Osmosis

Pressure Reduced Osmosis is being investigated as a green power source.   A prototype plant has been built in Norway.  We are still waiting for positive results.     The idea was introduced by RS Norman in 1974.  His concept is shown below.  Basically,  Water flows through the membrane  into the column of salt water. If the height ….  Read More

Scientific Method

A recent news article by Drs. Glazier and Ko from UCLA Health noted that a fecal transplant has been used to cure C diff.  With further reading, I learned that the process replaces diseased microbes with those from a healthy person.   This scientific method has been successful.  There are no known medicines for C diff.   ….  Read More

Welcome to Dr Osmosis

Hello, I am happy to be back.   And I would like to hear from you if you are reading this blog site.  Please leave a note in the comment section.     My blog site was attacked several months ago.   It is now more secure, and I will continue to review published findings about osmosis and osmosis ….  Read More

Osmosis: The Molecular Theory

Thank you for signing in to DrOsmosis.com.   We will delay public posts for awhile as we attempt to resolve the large number of attacks to our blog page.  This is not the first time I have developed Ideas that challenge the status quo.   I had an idea about the attacks I would get as I ….  Read More

Forward Osmosis

Osmosis is a natural process.   In its simplest form, water flows through the membrane into a solution.  It is important for plant and animal life.   Nutrients must enter cells and waste products leave.    Trees must bring nutrients from the soil to the upper most leaves (See: Maple Tree Details at DrOsmosis.com).    Experimenters found that a ….  Read More

OSMOSIS

One must fully understand the history to appreciate today’s textbook thermodynamic theory of osmosis.

Nobel Lecture by Jacobus H. van’t Hoff

van’t Hoff Nobel prize for his work with osmotic pressure. The theory of Osmosis is not the theory of osmotic pressure.. See Atkins applied pressure to a vessel of water raises the vapor pressure..

Osmosis History 2

Jean-Antoine “Abbe” Nollet (1700 – 1770) was a scientist and a priest.   He was noted for his scientific experiments with electricity, physics and for discovering Osmosis (1748).   He conducted a simple experiment with water, a membrane from an animal bladder, and wine.  Perhaps: he just wanted to find out why his Pee was yellow instead ….  Read More

Osmosis Experiment

What is difference between Osmosis and Diffusion?

 Osmosis is the movement of a solvent across a semi permeable membrane into a more dilute solution of the solvent.   The semi permeable membrane prevents the solute from passing through the membrane.    The original osmosis experiment used water and wine. Later experimenters found the same behavior using a sugar water solution instead of wine.    Various ….  Read More
