Evaluation of the effectiveness of mineral additives in cement systems in the development of “core – shell” photocatalytic compositions [PDF]

open access: yesНанотехнологии в строительстве, 2022
: Introduction. Creation of highly efficient photocatalysts for construction composites, which are characterized by increased activity and an extended spectral range of action, is a very important area of research. It is known that “core (substrate) –

Characterisation of Bee Pollen from the Marche Region (Italy) According to the Botanical and Geographical Origin with Analysis of Antioxidant Activity and Colour, Using a Chemometric Approach

open access: yesMolecules, 2022
Attempts have often been made to isolate and characterise monofloral pollens to correlate nutritional with botanical properties. Nevertheless, pollen harvested in a particular area that can have a high biodiversity could have healthier properties.

Influence of grain size, shape and compaction on georadar waves: example of an Aeolian dune

open access: yes, 2012
Many Ground Penetrating Radar (GPR) profiles acquired in dry aeolian environment have shown good reflectivity inside present-day dunes. We show that the origin of this reflectivity is related to changes in grain size distribution, packing and/or grain ...

3-D Granulometry Using Image Processing [PDF]

open access: yesIEEE Transactions on Industrial Informatics, 2019
Image-based methods for estimating the particle size distribution (granulometry) usually analyze two-dimensional (2-D) samples of particles disposed on a conveyor belt. Such approaches have to deal with occlusions and cannot evaluate the thickness of each particle.
