The size control is one of the most important factors during seed-growth process. Although precise determination of ingredients concentrations is easily controllable during the growth process, there is still a possibility to synthesize oversized particles. Nanosized fluorescent silica particles were synthetized using Stöber process and verified using three complementary methods of particle size determination, namely Dynamic Light Scattering (DLS), Particle Tracking (PT) as well as by Transmission Electron Microscopy (TEM) and Confocal Microscopy. The final diameter was verified by DLS and estimated to 494 nm. Parameters necessary to control the size were derived.

Knowledge is a corporate resource, being grounds for initiating activities, which is important in a dynamic economy. The difficulties related to obtaining tacit knowledge, related primarily to experience and observation of the knowledge employee (Mendryk, 2011), encourage the companies to use tools supporting knowledge management and location. This article attempts at designing a dedicated, strategic knowledge map for a research and development department in a manufacturing company. Based on the reference works, the detailed characteristics of specific sources of knowledge in a manufacturing company and tools supporting the process of converting the tacit knowledge into explicit one, for example, the knowledge maps, were devised. Then, a strategic knowledge map model was designed for the research and development department (hereinafter abbreviated as SKM – R&D) in the manufacturing company, comprising the following components: (1) fields of knowledge, (2) internal and external processes in the R&D department, and (3) sources of knowledge. Then, a practical implementation of the SKM – R&D model was presented.

This article elaborates the authors’ method for tacit knowledge acquisition focused on a research and development department in a manufacturing company. It presents a case study of the use of concepts for tacit knowledge acquisition and is based on a survey and data obtained from 85 Polish and German Manufacturing Companies from the cross-border cooperation region of Lubuskie/Poland – Brandenburg/Germany. This article develops a framework of tacit knowledge acquisition in a manufacturing company and further discusses the research results.
