"Shell Emergence". David S. Soriano


I was once a shell, Crouched in the dark, Too afraid to venture out, Too afraid to hark.

But then I heard a voice, A voice of hope, A voice that said, "You are sacred, Your life is yours to cope."

So I took a deep breath, And I stepped out of my shell, And I saw the world in a new light, And I knew that I could tell.

I could tell my story, I could share my light, I could inspire others, To find their own might.

So if you're feeling stuck, If you're feeling small, Just remember that you are sacred, And you have the power to crawl.

Crawl out of your shell, And step into the light, And see the world in a new way, And find your purpose in life.-   Bard ( AI/Google)

The Endless Streets. David S. Soriano


The streets are endless, dark and sullen, The rain is falling, cold and hopeless. I walk on, seeking happiness, Yet all I find is emptiness.

The world is a cruel place, And I am lost and alone. I long for a place of warmth and light, But I know it will never be mine.

So I walk on, through the endless streets, The rain still falling, the darkness closing in. I am lost and alone, and I will never find happiness.-  Bard (AI/Google)

Supercapacitor Prototype. Grafoil-Activated Carbon

 aq. sodium sulfate in a prelim bench-scale model.  Runs a 1.5V DC motor for 3 minutes. recharges fast. promising. Developing a six (6) electrode assembly for Farad increase. Dad Acquisition will be posted. 1.73V (open).  Polyurethane separator was used.  Steel electrode clip to be stapled to prevent fragile grafoil physical decomposition.


Zinc/ Bromine Secondary Cell Protortype/ Grafoil-Activated Carbon 1.8V (Open)


                                                Typical Grafoil/Activated  Carbon Cathode. Steel contact stapled to the fragile grafoil.

                                                     Zinc sulfate/ sodium bromide aq. electrolyte in halloysite nanotubular clay. The clay interacts electrostatically with the molecualr bromine . The tunnels afford mobility.  I will start collecting data soon.  It runs a small 1.5V DC motor with goos power for minutes. Rapid re-charge. Promising cell.

Superfast Outflow: Electrical Being . David S. Soriano


Superfast Outflow: Electrical Being

A spark-discharge, an open-system surge, A being of pure energy, a surging urge

To flow and be free, to spread and expand, To connect with all things, to never disband

A force of nature, a primal power, A spark of life that will never cower

Always moving, always changing, Always seeking new ways to rearrange

A being of pure potential, A force of nature, an electrical being-  Bard ( AI/Google)

Supercapacitor/ Battery/ Ultrabattery Research. David S. Soriano


  Ultra-fine activated carbon bonded ( with a slow -curing epoxy resin) to grafoil electrodes. Dried 24 hours at 20 deg C.  An open system with the duo-electrodes in 25% (m/v) sodium sulfate electrolyte with polyurethane separator. rapid charge over 1.7 V and runs a small DC motor. promising. Re-charge demonstrated a strong supercap.  Specs to be collected and presented.

         Lead batteries continue to be important.   Here, I coated a thin strip of fresh lead with a paste of red lead ( PbO2). I use sodium sulfate/ water and lead salt as the paste. I dry at 100 deg c for 30 minutes. I place the electrode in a small 3.5" plastic device with unpainted lead as the other electrode. Seperated by the polyurethane material. Close contact but no short. Raid charge to 2.2V. Cutoff at 1.75 V for now. Runs small DC motor.   25% aq. H2SO4 as electrolyte.  Safe system for evaluating electrodes, separators and electrolytes. I work with undergrads and want safety and health first. I will collect data and report here. I will create such cells with Ni/Zn, the Pb/Pb, and duo-grafoil siupercaps and ultra-cells.

              I will also post images of the excellent "ZB Tech"  devices I use in battery/ supercap cycles studies.   I am lucky to have six 96) in my lab for my students and I.

Transitory Nature of Life. AI Collaboration. David S. Soriano


The Transitory Nature of Life- by Bard ( AI/Google)
Life is a fleeting breath,
A wisp of smoke in the wind.
It comes and goes so quickly,
Like a dream that leaves you blind.
But even though life is brief,
It's filled with love and light.
With care and concern for others,
We can make the most of our night.
So let's not waste a single moment,
But live each day to the fullest.
For we never know when our time will come,
And our lives will be turned to dust.

Supercapacitor Research


                                                        Ultra-fine activated carbon sprinkled on epoxy resin-coated grafoil as current collector.  With disposable gloves on, I press the carbon down and sprinkle some more. I leave it 24 hours ar 20 deg C. to cure.  My objective is to study selected "deep eutectic solvents" as electrolytes and some gel electrolytes.

                                          Why open factory-issued supercapacitors tof lush out the electrolytes in order to test new ones?  I use a CD case and place a strip of polished aluminum in the case. I apply epoxy resin and sprinkle on ultra-fine activated carbon (see above). Strips of "porous surgical tape" are applied over the carbon when dried. This will aloow ion mobility. I also place a thin sheet of paper towel over the surface and a second strip of activated carbon-coated aluminum to complete the candidate supercap. 30% aq. phosphoric acid serves as the electrolyte. In 60 seconds, I observed 1.3V and there is no obvious short.

A range of electrolytes and gel electrolytes will be tested this way before creating cylindrical supercaps.
