Simonkolleite is a zinc-layered hydroxide salt with the formula Zn5(OH)8Cl2·H2O. It has a platelet morphology and can be used for many applications, owing to both its layered structure and its nature as a hydroxide salt. It can be prepared via a sim

The large electromechanical coupling coefficient of langasite makes possible the production of monolithic filters with much wider bandwidth than are achievable on quartz. In this paper we present a new design method for eight-pole band-pass filter us

Due to material nonlinearities the parameters of the SAW propagating on the substrate will be changed somewhat when the substrate is subjected to strong external fields. The most important external fields are the acceleration, the electric field, the

The effects of low‑phosphorus diets with two levels of phytase were examined in broiler chickens using eight replicates per treatment. The diets contained 40 % of spring barley with either 201 or 305 phytase activity units per kg. Chromic oxide was
