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

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

Endosmometer by Dutrochet

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 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

Osmosis

After our papers on seed storage were rejected several times, we found that our design approach for seed storage warehouses was different from published works on the theory of osmosis.   We had several warehouses installed around the country.   All installations  are still working.   They are maintaining temperature and relative humidity at design conditions.    Either the ….  Read More

Water Purification

Water Purification Osmosis, the simple experiment of a column of wine capped at the bottom with a membrane from a pig’s bladder and immersed into a vessel of pure water has intrigued many for 200 years.  Although Priest Nollett expected that the column of wine would force flow downward through the membrane into the water, ….  Read More

Covid-19

Covid-19 pandemic has opened my eyes to the incredible complexity of the human body and to the many scientists and engineers that have improved our understanding and are working on developing solutions. We still have a long way to go

Cell Transport Models

We have looked at vesicles, cell behavior, and biological osmosis.    Basically, living organisms are composed of single or multiple cells.    From the “Fundamentals of Medical Physiology”,   we know that the cell is the smallest unit of life and  cells are the fundamental building block of all living things.    Cells take in nutrients to generate energy ….  Read More

Honey

Honey is a natural topic for Valentine’s Day.   Here, we are discussing natural honey.  A sweet viscous liquid produced by honeybees.     A hive of honeybees can produce 100 pounds of extra honey annually and contains more than 60,000 bees.  Each bee produces a partial spoonful of honey during its three to 5-week lifetime.  There are ….  Read More
