Nanopesticide application should enable efficient pest management with smaller doses of an active ingredient. Nevertheless, the environmental risk assessment nanopesticides is currently in its initial stages due to limited access nanopesticides. Therefore, we synthesised nanofungicides captan as organic ingredient and ZnO35–45nm or SiO2 20–30nm nanocarriers ([email protected] [email 20–30nm) evaluated their by testing different microbial parameters potential biomarkers. First,...

Owing to their remarkable physical properties, cellular structures, such as triply periodic minimal surfaces (TPMS), have multidisciplinary and multifunctional applications. Although these structures are observed in nature, examples of TPMS with large length scales living organisms exceedingly rare. Recently, microstructure reminiscent the diamond-type was documented skeleton modern knobby starfish Protoreaster nodosus . Here we report a similar microlattice 385 Myr old crinoid Haplocrinites...

The mayenite group includes minerals with common formula Ca12Al14O32-x(OH)3x[W6-3x], where W = F, Cl, OH, H2O and x 0-2. This distinction in the composition is associated site which may remain unoccupied or be occupied by negatively charged ions: OH-, F-, Cl-, as well neutral molecules like H2O. However, there no experimental approach to easily detect differentiate mineral species within group. Electron micro-beam facilities energy- wavelength-dispersive X-ray detectors, most tools...

Abstract Preservation of soft parts (collagen fibres, blood vessels and cells) in extinct vertebrates is rare usually limited to fossilized bone cartilage. Well-preserved coarse collagenous fibre bundles embedded a mineralized matrix tendons, as well numerous hollow, tubular structures consistent morphologically with fibril bundles, associated cells, were identified ossified tendons Late Cretaceous ornithischians from North America Central East Asia. Detailed, high-accuracy imaging, along...

Chlorellestadite (IMA2017–013), ideally Ca5(SiO4)1.5(SO4)1.5Cl, the Cl-end member of ellestadite group was discovered in a calcium-silicate xenolith rhyodacite lava from Shadil Khokh volcano, Greater Caucasus, South Ossetia. forms white, tinged with blue or green, elongate crystals up to 0.2–0.3 mm length. Associated minerals include spurrite, larnite, chlormayenite, rondorfite, srebrodolskite, jasmundite and oldhamite. The empirical crystal chemical formula holotype specimen is...

Slags from the historic metallurgy of Zn-Pb ores are known for unique chemical and phase compositions. The oxides, silicates, aluminosilicates, amorphous phases present therein often contain in structure elements that rare natural conditions, such as Zn, Pb, As. study focuses on processes occurring contact melted batch refractory materials build furnace, which lead to formation these phases. To describe them, (X-ray fluorescence (XRF), inductively coupled plasma mass spectrometry (ICP-MS))...

Rusinovite, Ca10(Si2O7)3Cl2, was found at two new localities, including Shadil-Khokh volcano, South Ossetia and Bellerberg Caspar quarry, Germany. At both of these rusinovite occurs in altered carbonate-silicate xenoliths embedded volcanic rocks. The occurrence this mineral is connected to specific zones the xenolith characterized by a defined Ca:Si < 2 ratio. Chemical compositions, as well Raman spectra investigated samples, correspond data from locality holotype—Upper Chegem Caldera,...

Excrement-shaped ferruginous masses have been recovered from the Miocene of Turów mine in south-western Poland. These siderite subject much controversy, having interpreted either as being coprolites, cololithes or pseudofossils created by mechanical deformation plastic sediment. Here we present results mineralogical, geochemical, petrographic and microtomographical analyses. Our data indicate that these consist iron oxide rather than phosphate, rarely contain recognizable food residues,...

Abstract Excrement-shaped siderite masses have been the subject of much controversy. They variously interpreted either as being coprolites, cololites or pseudofossils created by mechanical deformation plastic sediment. Here we report excrement-shaped ferruginous recovered from Miocene Turów mine in south-western Poland. Mineralogical, geochemical, petrographic and microtomographical analyses indicate that these consist iron oxide rather than phosphate, rarely contain recognizable food...
