While some scientists are hard at work investigating phenomena beyond Earth, others are still making new discoveries on our planet. Among the discoveries that keep piling up are theidentification of various semiprecious stonesand minerals. In fact, there are more than 5,000 different types of mine...

The main component of talc is magnesium silicate containing water, and the molecular formula is Mg3[Si4O10](OH)2. Talc belongs to the monoclinic system. Crystals are pseudo-hexagonal or rhombic flakes, occasionally. Usually into dense massive, leaf-like, radial, fibrous aggregates. It is color...
growth of calcium oxalate (CaOx) crystals regulated by Auricularia auricular polysaccharides (AAPs) with different viscosity-average molecular weights ( M v ), the toxicity of AAP-regulated CaOx crystals toward HK-2 cells, and the prevention and treatment capabilities of AAPs for Ca...
Marbles have been made of all kinds of materials throughout history. When thinking about kinds of marbles we have to consider how they were made.The ealiest marbles were round stones or clay balls. Through the centuries marbes have been made of marble and other stones, clay, porcelain, ...
Polysaccharides reportedly exert protective and repair effects on oxidative damage to cells, which reduces the incidence of kidney stones11. In our previous study12, we investigated the antioxidant and repair abilities of green tea polysaccharide (TPS) with various Mws on injured renal epithelial cells...
Crystallization is a two-stage kinetic process that begins with the formation of a nucleus and then continues with the accumulation of ions on it. The shapes of the crystals depend on the degree of undercooling (ΔT), and euhedral crystals, having characteristic forms that reflect their ...
Nowadays, in the innovative field of tissue engineering, different kinds of scaffolds, i.e., temporary support that aids seeded cells to proliferate and reorganize themselves into tissue-like structures, hold a strategic position [21]. Several different polymeric scaffolds have been developed with the...
as commercial syrups, without the syrup itself. Homeopathic elixirs are usually a mix of grain alcohol, such as vodka, with water and herbs. Some magical practitioners and herbalists also soak crystals in their elixirs, believing that healing energies from the stones will leach into the liquid...
Solvents are widely used in crystallization, but their effects on the shape development of crystals are under debate. Here, we report a view on how solvents play their role by considering the viscosity of solvents. We synthesize silver particles in a mixture of alcohol and water. The viscosity...
