Three new species of arbuscular mycorrhizal fungi of the genus Diversispora from maritime dunes of Poland
(Taylor & Francis, 2022-03-31)
Three new species of arbuscular mycorrhizal fungi of the genus Diversispora (phylum Glomeromycota) were described based on their morphology and molecular phylogeny. The phylogeny was inferred from the analyses of the partial 45S rDNA sequences (18S-ITS-28S) and the largest subunit of RNA polymerase II (rpb1) gene. These species were associated in the field with plants colonizing maritime sand dunes of the Baltic Sea in Poland and formed mycorrhiza in single-species cultures.
Silica-coated admixtures of bismuth and gadolinium oxides for 3D printed concrete applications: rheology, hydration, strength, microstructure, and radiation shielding perspective
(Elsevier B.V., 2025-03-05)
This study examines the impact of replacing up to 5 vol% of Portland cement (PC) with both pristine mixture of Bi2O3/Gd2O3 (BG) and silica-coated BG particles. Two different types of silica coatings, each with varying synthesis methods, were applied to coat the BG structures, and their impact on the fresh, hardened, microstructure and radiation-shielding performances of the 3D printed concrete (3DPC) was investigated. Isothermal calorimetry demonstrated that pristine BG incorporation delays hydration, whereas silica coatings mitigate this, with type A coating being more effective. Early compressive strength was reduced in BG-containing mixes but normalised after seven days. Rheological tests showed that BG additives enhanced thixotropy and yield shear stresses, with 2.5 vol% being optimal, especially with method B coating. Green strength properties improved significantly with method B coated particles, showing up to 62.4 % and 57.7 % increases in strength and modulus, respectively, after 30 minutes. Micro-CT and MIP analyses confirmed reduced porosity and refined pore structure with silica coatings. Radiation shielding tests indicated superior performance in uncoated BG mixes, with method B coating providing superior shielding performance compared to that of method A coatings due to their higher surface area. In general, silica-coated BG particles enhance the mechanical, rheological, and radiation shielding properties of 3DPC, with method B coatings offering the most significant benefits.
