“…Jenike flow index ffc is defined ffc = σ1/σc. The relationship between ffc and the flowability -not flowing materials (ffc<1), very cohesive (ffc<2), cohesive (<4), easy flowing (<10), free flowing (>10) [10].…”

“…These include particle size and shape, XRD patterns, shear properties (angle of internal friction and wall friction), bulk properties (compressibility, permeability) or sensitivity of powders to fluidization, so-called aeration. Shear, bulk properties and aeration are influenced, for example, by the amount of air contained, which affects the interaction of particles and therefore also their flow and handling (storage, transport, packaging, process steps) [9,10]. Based on the knowledge of the above characteristics, it is possible to modify the process, product formulation, qualitatively compare different production batches, manufacturers or innovate application possibilities, which are currently numerous.…”

Zinc oxide plays an important role in various industries from electronics to cosmetics. Due to its special characteristics such as antiseptic, astringent and fungistatic properties, anti-corrosion, low electron conductivity and good heat resistance is still the subject of current research. Therefore, friction parameters, compressibility factors, flowability and sensitivity to aeration have been investigated. For this purpose, two nano and one micro-sized ZnO powders were characterized and compared. Experimental work was performed by the Powder Rheometer and Disk Centrifuge. Also a shape analysis of samples were made. The subjects were questions like -how easy consolidated nano/micro ZnO powders will begin to flow or how volume changes as a function of applied normal stress. The first results showed that the slight variations in the shape and size of the ZnO particles could cause differences in the behaviour of the tested powders.

“…Nanoparticles (NPs) are widely employed in the environment due to their unique optical, electronic and magnetic characteristics [1,2,3]. Among the NPs, Zinc oxide nanoparticles (ZnO-NPs) are used in several industries, medicine and agriculture [4,5], due to their unique characteristics which differ from their particular bulk counterparts of the same synthesis [6,7], such as morphology, size and distribution [8]. The NPs are also used in the gene delivery [9] ( Manna and Bandyopadhyay, 2019) or as a synthetic drug [10,11,12].…”

We appraised the use of zinc oxide nanoparticles, (ZnO-NPs) and zinc oxide bulk (ZnO-bulk) or zinc acetate, as a natural nematocide, alone or in combination with oxamyl in vitro and in vivo trials in order to improve systems for root-knot nematode (RKNs) control in banana plants. Especially, ZnO-NPs were biosynthesized from the alga, Ulva fasciata. In general, all applications of ZnO-NPs were more effective to control RKNs than ZnO-bulk as well oxamyl alone (chemical control). In in vitro conditions, ZnO-NPs with oxamyl showed 98.91% second stage juveniles2 (J2s) mortality of Meloidogyne incognita after 72 hrs, while 72.86% mortality was observed at the same NPs treatment without oxamyl at the same exposure time. The same treatment was the most effective in diminution of J2s community (82.77%) in soil and galls number (81.87%) in roots under in vivo conditions. In contrast, the highest weight and height of the shoot was observed in Zn-bulk treatment in combination with oxamyl as well oxamyl only (nematocides check). Scanning electron microscopy (SEM) reports displayed the distributions and accumulations of ZnO-NPs on the nematode (J2s) body under direct exposure, which might be the reason of NP-mediated toxicity and disruption for M. incognita. HighlightsZno-NPs biosynthesis by macrogreen alga Ulva fasciata and give nanorode particles. Biogenic ZnO-NPs were used as nematocidal against root-knot nematodes (RKNs) solely and in combination with oxamly in vitroand in vivo.ZnO-NPs exhibited high nematocidal activity in vitroand in vivo.Banana plants infected with RKNs and treated with ZnO-NPs in combination with oxamly showed high growth. Statement Of NoveltyThis study offers importance of green technology for the development of biosynthesis ZnO-NPs, and in combinations with oxamyl in control RKNs (in vivo and in vitro). Moreover, it is possible using biosynthesis ZnO-NPs in alternative to pesticide and also to enhancement the plant yields. nematode body with magni cation 500x, f) ZnO-NPs attached to the nematode body with magni cation 1500x.
