A new tungsten boride has been prepared and has been assigned the formula WB(2). The assignment is based on comparison of the x-ray diffraction data of this boride with those of diborides of the AlB(2) type structure. Values of a(0) = 3.02 and c(0) = 3.05 were calculated for a hexagonal unit cell.

This study shows that it is possible to shift the polymorph of pharmaceuticals through crystallization in a nanocellulose gel. This is a demonstration of using natural materials that are readily surface modified to form a tailored environment for drug crystallization.
