Calcofluor-white Calcofluor-white Calcofluor-white is a special fluorescent stain that binds strongly to structures containing cellulose and chitin. In plant cell biology research, it is used for the staining of cell walls of both algae and higher plants. It is also useful in medicine and animal biology for the identification of fungi in the tissue, (it binds to the chitin in the cell walls of the fungi). In research, calcofluor-white is also used to stain bud scars of yeast cells because the bud scars have a higher content of chitin, which stains them more than the rest of the cell membrane. Due
Natural building construction, as hempcrete's density is 15% that of traditional concrete. Rammed earth is a wall system made of compacted earth, or another material that is compacted. It is extremely strong and durable. Quality rammed earth walls are dense, solid, and stone-like with great environmental benefits and superior low maintenance characteristics. As an option depending on climate rigid insulation can be placed inside the wall. Similarly, depending on seismic concerns bamboo or other tensile natural materials can be used to reinforce the wall. Rammed earth has been used for around 10,000 years in all types of buildings from low rise to
