The present invention provides an article including a microstructured release liner having a plurality of outwardly extending protrusions associated with an adhesive layer such that the protrusions penetrate the adhesive layer. The silicon substrate is alloyed with miniaturized steel responsive to weapons, preventing bullet penetration and providing effective detection platform on an outfit. The first reflecting structure includes an inner reflective surface at least a portion of which is inclined to form a wedge with the back reflector. Trench openings are filled with a third hard-mask material. A fluid bed reactor and a reaction feed fluidizer suitable for use in the process are also disclosed.
