Screens of antioxidant activity (AA) of various natural products have been a focus of the research community worldwide. This work aimed to differentiate selected samples of Merlot wines originated from Montenegro, with ...
Hard template synthesis of nanomaterials based on mesoporous silica
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Diverse hard template synthetic methodologies are being employed for the synthesis of mesostructured metal oxide and carbon nanomaterials, with the application of mesoporous silica as the hard template. We describe the ...
Determination of Flavonoids and Total Polyphenol Contents in Commercial Apple Juices
(Czech Academy Agricultural Sciences, Prague, 2018)
We propose a sensitive and selective spectrofluorimetric method for the determination of flavonoids as expressed in 'quercetin equivalent' in apple juices. The method is based on the strong emission of the aluminium(III)-quercetin ...
Root malate efflux and expression of TaALMT1 in Serbian winter wheat cultivars differing in Al tolerance
(Sociedad Chilena de la Ciencia del Suelo, 2018)
Aluminium (Al) toxicity in acid soils is a global problem. Here, we investigated Al tolerance in high yielding winter wheat (Triticum aestivum L.) cultivars bred in Serbia. The common relative mot length (RRL) test for Al ...
Resistance to external sulfate attack - Comparison of two alkali-activated binders
(E D P Sciences, Cedex A, 2018)
Durability of binders, mortars and concretes in aggressive environments is of crucial importance for their commercial application. In this paper the resistance to external sulfate attack of two different alkali-activated ...
Some sigmoid and reverse-sigmoid response patterns emerging from high-power loading of solids
(Srpsko društvo za mehaniku, Beograd, 2018)
The objective of the present review is twofold. First, it aims at highlighting some sigmoid and reverse-sigmoid response patterns observed recently in the course of simulations of the high-strain-rate loading of (mostly, ...
