Modification of natural clinoptilolite and ZSM-5 with different oxides and a study of the obtained products in lignin pyrolysis
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, different metal oxides (MO) supported on two types of zeolites: 1) natural clinoptilolite (NZ) and 2) synthetic zeolite, ZSM-5 were prepared and tested as catalysts in the fast pyrolysis of hardwood lignin. ...
Reliable prediction of heat of vaporization of n-alkanes at 298.15 K / Pouzdan model za predskazivanje toplote isparavanja n-alkana na 298,15 K
(Serbian Chemical Society, Belgrade, 2010)
A reliable model for the prediction of the heat of vaporization for n-alkanes at 298.15 K with the number of carbon atoms and normal boiling point as the only input parameters is recommended. The new model is compared with ...
Electrochemical deposition and characterization of AgPd alloy layers
(Srpsko hemijsko društvo, Beograd, 2018)
The AgPd alloys were electrodeposited onto Au and glassy carbon disc electrodes from the solution containing 0 001 mol dm(-3) PdCl2 + 0.04 mol dm(-3) AgCl + 0.1 mol dm(-3) HCl + 12 mol dm(-3) LiCl under the non-stationary ...
Immobilization of maltase from Saccharomyces cerevisiae on thiosulfonate supports
(Srpsko hemijsko društvo, Beograd, 2016)
In this study, two commercial supports (Eupergit (R) C and Purolite (R) A109) were chemically modified in order to introduce thiosulfonate groups, which could subsequently exclusively react with the cysteine residues on ...
Sepiolite functionalized with N-[3-(trimethoxysilyl)propyl]ethylenediamine triacetic acid trisodium salt. Part I: Preparation and characterization
(Srpsko hemijsko društvo, Beograd, 2015)
Natural sepiolite from Andrici (Serbia) was functionalized by covalent grafting of N-[3-(trimethoxysilyl)propyl]ethylenediamine triacetic acid trisodium salt onto the Si-OH sepiolite groups. The functionalized material, ...
Biosynthesis of silver-based nanoparticles on polypropylene non-woven material for efficient antimicrobial activity / БИОСИНТЕЗА НАНОЧЕСТИЦА НА БАЗИ СРЕБРА НА НЕТКАНОМ ПОЛИПРОПИЛЕНСКОМ МАТЕРИЈАЛУ ЗА ЕФИКАСНУ АНТИМИКРОБНУ АКТИВНОСТ
(Serbian Chemical Society, 2023)
The outbreak of the COVID 19 pandemic confirmed the importance of personal protective equipment including the respiratory face masks as barriers to pathogens. Taking into account that face masks are mainly composed of ...

Effective valorisation of barley bran for simultaneous cellulase and beta-amylase production by Paenibacillus chitinolyticus CKS1: Statistical optimization and enzymes application
(Srpsko hemijsko društvo, Beograd, 2017)
The agricultural raw industry generates large amounts of annually by-products that create disposal problems. Hitherto, there have been no reported papers about the simultaneous production of cellulase and beta-amylase from ...
An apparatus proposed for density measurements in compressed liquid regions at pressures of 0.1-60 MPa and temperatures of 288.15-413.15 K
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, an apparatus for density measurements in the compressed liquid regions is presented. This installation is based on the use of a DMA HP density measuring cell and a DMA 5000 densimeter (both instruments are ...
Antiosteogenic effect of arsenic trioxide, cholecalciferol, lovastatin or their combination in vitro
(Srpsko hemijsko društvo, Beograd, 2019)
Pathological formation of bone in non-skeletal soft tissues or heterotopic ossification (HO), for which there is currently no effective treatment, is considered to be mediated by activation of Hedgehog (Hh) signaling ...
