Creating a cleaner world through the science of gaps.

AboutAbout the lab
Tackling societal challenges with membranes and clean technology.
The Pore Physical Chemistry Lab (Sivaniah Lab) is based at the Institute for Integrated Cell-Material Sciences (iCeMS) at Kyoto University and operates as "Pureosity Labs."
Centered on membrane science and clean technology, the lab addresses challenges such as reducing emissions of harmful substances and energy-efficient water purification.
Through joint research, industry-academia collaboration, and starting companies, the lab aims to bring its research results to society.
A spin-out company has also emerged from the lab.
Key terms
- Separation membrane
- A thin membrane that lets only specific components of a gas or liquid pass through, or blocks them.
- Water repellency
- The property of a surface repelling water, like a lotus leaf.
- Carbon quantum dot
- A tiny carbon particle, a few nanometers across, that emits fluorescence when illuminated.

Centered on membrane science and clean technology, the lab tackles challenges such as reducing emissions of harmful substances and energy-efficient water purification. It studies materials that make use of gaps and fine structures, including a printing technology that uses light to create foam structures in materials, membranes that separate carbon dioxide, and fluorescent carbon particles made from plants and other sources.
*Illustrative imagePrinting Whiteness with Foam Structures
Using only light and a mild solvent, the lab created fine foam structures inside a material and developed a technology that produces strong whiteness and water repellency without titanium dioxide or fluorinated chemicals. It can also be used for printing at an ultra-high resolution of 20,000 DPI.
*Illustrative imageMembranes That Separate Carbon Dioxide
The lab made composite membranes by mixing nanocellulose into rubbery PEO-based polymers and investigated their performance as separation membranes for capturing carbon dioxide.
*Illustrative imageGlowing Carbon Particles Made from Plants
The lab is researching the use of carbon quantum dots made from biomass as fluorescent probes that make inflammation visible and suppress it, and as materials for observing cells while relieving oxidative stress in plants.
