Sodium gluconate has been shown to compensate the impact of alkalis on the long term strength development of cement pastes. This work studies the impact of sodium gluconate combined with Na2SO4 on the microstructural development of white cement-slag system ...
Polyphosphate plays an important role in the physiological adaptation of bacteria during growth and development, as well as in their response to nutritional and environmental stresses. Moreover, polyphosphate accumulation is of environmental relevance and ...
The Fenton reaction was discovered over 120 years ago, yet our understanding of the complete reaction mechanism of the seemingly simple iron and hydrogen peroxide reaction (Fe + H2O2) remains unclear, thus limiting its full potential. In this work, the aim ...
Synthetic bone graft substitutes based on PLLA have been largely studied during the past decade. PLLA/hydroxyapatite composites appear as promising materials for large bone defect healing. In this study dense PLLA/nano-hydroxyapatite composites were prepar ...
This study investigates the microstructure, phase formation, and mechanical properties of LC3-50 based auto-claved aerated blocks. The microstructure and phase formation is studied using SEM-EDS and X-ray diffraction techniques. The fresh and hardened prop ...
Etched Al of uniform quality is obtained at a const. rate by pptg. Al(OH)3 from the bath with simultaneous regeneration of the NaOH or KOH. The pptn. is promoted by addn. of Na2CO3. Filterability of the ppt. is improved by the addn. of complexing agents, e ...
The toxicity of two types of ultra-small zeolites (8–18 nm) with LTL- and EMT-type structures is reported. Both the LTL- and EMT-type zeolites belong to the same group of molecular sieves; they have large pores (7.1–7.5 Å) and low silica content (Si/Al = 1 ...
Oxidation of the antimicrobial agent triclosan by aqueous ozone (O-3) was investigated to determine associated reaction kinetics, reaction site(s), and consequent changes in antibacterial activity of triclosan. Specific second-order rate constants, k(O3), ...
