Metal oxide nanoparticles for safe active and intelligent food packaging
(Elsevier Science London, London, 2021)
Background: Food safety and food security remain the major concern of consumers and the food industry. Bacterial contamination continues to be a crucial food safety issue. Smart packaging incorporates both active and ...
Nitrate does not result in iron inactivation in the apoplast of sunflower leaves
(Amer Soc Plant Biologists, Rockville, 2003)
It has been hypothesized that nitrate (NO3-) nutrition might induce iron (Fe) deficiency chlorosis by inactivation of Fe in the leaf apoplast (H.U. Kosegarten, B. Hoffmann, K. Mengel [1999] Plant Physiol 121: 1069-1079). ...
Phosphorus deficiency is the major limiting factor for wheat on alluvium polluted by the copper mine pyrite tailings: a black box approach
(Springer, Dordrecht, 2011)
Failures of tailings dams have degraded large areas of agricultural alluvial soils worldwide, and concomitant soil pollution studies are abundant. Yet, the data on the actual effects of thereby imposed stresses on major ...
Phenolic Profiling of 12 Strawberry Cultivars Using Different Spectroscopic Methods
(Amer Chemical Soc, Washington, 2020)
Phenolic compounds of 12 strawberry cultivars were profiled using spectrophotometry, spectrofluorometry, and high-performance liquid chromatography-mass spectrometry, coupled with multivariate regression analysis. Total ...
Mechanical and microstructural properties of alkali-activated fly ash geopolymers
(Elsevier, Amsterdam, 2010)
This paper investigates the properties of geopolymer obtained by alkali-activation of fly ash (FA), i.e. the influence of characteristics of the representative group of FA (class F) from Serbia, as well as that of the ...
Nanoindentation study of nickel manganite ceramics obtained by a complex polymerization method
(Elsevier Sci Ltd, Oxford, 2016)
The chemical synthesis of nickel manganite powder was performed by a complex polymerization method (CPM). The obtained fine nanoscaled powders were uniaxially pressed and sintered at different temperatures: 1000-1200 degrees ...
Effects of the concentrated NH4NO3 solution on mechanical properties and structure of the fly ash based geopolymers
(Elsevier Sci Ltd, Oxford, 2013)
The geopolymers based on fly ash were exposed to the concentrated (6 M) NH4NO3 solution for 540 days. The highest compressive strength decrease occurred in the initial 28 days testing period. Study of the effects of the ...
Toxicity investigation of CeO2 nanoparticles coated with glucose and exopolysaccharides levan and pullulan on the bacterium Vibrio fischeri and aquatic organisms Daphnia magna and Danio rerio
(Elsevier, Amsterdam, 2021)
Cerium oxide nanoparticles (nCeO(2)) have widespread applications, but they can be hazardous to the environment. Some reports indicate the toxic effect of nCeO(2) on tested animals, but literature data are mainly contradictory. ...
Organic manure stimulates biological activity and barley growth in soil subject to secondary salinization
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
A pot experiment was performed to compare the impact of organic manure on soil enzymatic activity, respiration rate and the growth of two barley cultivars (Hordeum vulgare L.) differing in their salt tolerance under a ...
Photosynthesis Enhancement in Maize via Nontoxic Orange Carbon Dots
(Amer Chemical Soc, Washington, 2021)
The sustained increase in leaf photosynthesis may increase crop yield. Due to many limitations, plants use much less photosynthetic capacity than is theoretically possible. Plant nanobionics investigates nanoparticle ...
