Štore Steel Ltd. is one of the biggest flat spring steel producers in Europe. The main motive for this study was to influences non-metallic inclusions on mechanical properties obtained by tensile testing. From January 2016 December 2021, all available strength data (472 cases–472 test pieces) 17 low alloy grades, which were ordered and used final user rolled condition, gathered. Based geometry ...

The effect of limestone replacement in the reaction and phase assemblage evolution two sodium sulfate activated slag cements was investigated. composition its reactivity influenced kinetics these materials. Paste with addition exhibited an acceleration kinetics, particularly for slowly reacting slags. Ettringite aluminium substituted calcium silicate hydrate were identified as main products cem...

Abstract Mo(Si,Al) 2 with different yttrium (Y) additions (up to at.%) was synthesised by dry powder mixing followed compaction and sintering. In as-sintered materials, Y present as aluminium garnet. The materials were exposed in air at 1500 °C for up 250 h study the effect of on oxidation behaviour. oxides formed investigated using scanning electron microscopy (SEM)-based techniques X-ray diff...

OBJECTIVE To compare the delivery and retention of triclosan in dental plaque, and to compare the antibacterial efficacy of a newly developed toothpaste to a marketed calcium carbonate toothpaste. METHODS Two clinical delivery/retention studies were carried out to determine the concentration of triclosan in plaque 10 minutes, and two and four hours after brushing with a new triclosan-containi...

Cement is the most utilized material in the world. It is a highly versatile material, with remarkable mechanical properties and chemical durability. However, concomitant to these positive attributes is the massive quantity of CO2 emitted during its manufacturing, accounting for roughly 5% of global anthropogenic carbon dioxide emissions. Researchers have long pursued modifications to the manufa...

The effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male Wistar rats were investigated. Daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations ...

Organic molecules, such as pharmaceuticals, agro-chemicals and pigments, frequently form several crystal polymorphs with different physicochemical properties. Finding polymorphs has long been a purely experimental game of trial-and-error. Here we utilize in silico polymorph screening in combination with rationally planned crystallization experiments to study the polymorphism of the pharmaceutic...

Single crystal X-ray structures of two polymorphs of (2-fluoro-3-pyridyl)(2,2'-biphenyl)borinic 8-oxyquinolinate: orthorhombic (space group Pca21), and triclinic (space group P1̄) have been established and analysed. A fast rate of crystallization results in the orthorhombic polymorph, whereas slow crystallization gives the triclinic polymorph. Physicochemical and theoretical results prove that b...

The high-pressure polymorphs of CuI have attracted much attention due to the somewhat contradictory identification of their structures by means of x-ray diffraction measurements and theoretical calculations. In this paper, we report the results of a theoretical investigation of polymorphs of CuI including zinc-blende, rhombohedral, tetragonal, rocksalt and orthorhombic phases. We find that CuI...
