Lázlo Zechmeister was one of the pioneers in chromatology. He recognized the potential of the chromatographic method and made extensive use of it for his research about natural products. In 1938 he founded the book series "Progress in the Chemistry of Organic Natural Products" which includes review articles on contemporary research by masters in their fields of expertise. This text casts light on his life and his pioneering role in chromatography and provides more detailed insight on the book series.

These test methods of chill testing apply to gray irons that are to be free of chill in the casting and to chilled irons that are to have a specific depth of chill in the casting. Two test methods of determining the chilling tendencies of cast iron are covered as follows. For many applications either test method will be satisfactory if test pieces of the proper dimensions are selected.

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. Additively manufactured TPU mould is developed to cast complex concrete structures. A planar topologically optimized cantilever and a free-form 3D column are cast using the proposed TPU mould. Good surface quality is obtained for the cast concrete elements, and the moulds can be reused many times after cleaning.

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.
