Barium titanate vehicles. Due to their elevated biocompatibility, barium titanate nanoparticles (BTNPs) have been recently employed as nanocarriers for drug delivery. Magnetoelectric effect of giant strengths have been reported in thin films grown on barium titanate substrates. Barioperovskite is a very rare natural analogue of BaTiO, found as microinclusions in benitoite. Barium titanate Barium titanate is an inorganic compound with chemical formula BaTiO. Barium titanate appears white as a powder and is transparent when prepared as large crystals. It is a ferroelectric ceramic material that exhibits the photorefractive effect and piezoelectric properties. It is used in capacitors, electromechanical transducers and nonlinear optics.
Sterling silver products. Colonial silversmiths used many of the techniques developed by those in Europe. Casting was frequently the first step in manufacturing silver pieces, as silver workers would melt down sterling silver into easily manageable ingots. Occasionally, they would create small components (e.g. teapot legs) by casting silver into iron or graphite molds, but it was rare for an entire piece to be fabricated via casting. Next, silversmiths would forge the ingots into the shapes they desired, often hammering the thinned silver against specially shaped dies to "mass produce" simple shapes like the oval end of a spoon. This process occurred
