Oxygen reduction on iron-V. Processes in boric acid-borate buffer solutions in the 7.4-9.8 pH range
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
O2 and H2O2 reduction was studied on Puratronic iron (99.995%) in borate buffer solutions of various pH ranging from 7.4 to 9.8. In solutions of pH < 9.3 the E-j curves are of quite irregular shapes and the limiting ...
Study on the pyrolysis products of two different hardwood lignins in the presence of NiO contained-zeolites
(Elsevier Ltd, 2017)
Several NiO contained-zeolites (NiO/H-ZSM-5, NiO/H-BETA and NiO/H-Y) prepared by a mechanochemical dry milling (MCDM) were tested in the pyrolysis of two hardwood lignins: Eucalyptus (EUC) and a mixture of birch and aspen ...
Compression hysteresis of fibrous systems
(John Wiley & Sons Inc, Hoboken, 2008)
This investigation deals with the compression of fibrous systems with oriented distribution of fibers into yarns, which are incorporated in a particular way into fabrics (by weft knitting technology). The compression ...

V prispevku predstavljamo sintezo in karakterizacijo serije tekočih kristalov z upognjeno sredico. Upognjeno sredico sestavljajo 3 benzenski obroči povezani z azocinamoilno skupino in še 2 povezana z fotoobčutljivim AZO ...
Pattern recognition methods for classification of soils based on their radionuclide content
(Belgrade : The Society of Physical Chemists of Serbia, 2006)
Multivariate data analysis methods were used to recognize and classify soils of unknown geographic origin. A total of 103 soil samples were differentiated into classes,
according to regions in Serbia and Montenegro from ...
The Application of Recycled Wool-based Nonwoven Material for Removal of Oil from Water
(Proceedings “Futurotextiles“ International Conference, 23-24 November 2006, Lille, France, 2006)
The aim of this study was to investigate the potential utilities of recycled wool-based nonwoven material for removal of different kinds of oil from water. Sorption capacities of the material in water, oil retention, sorbent ...
Activation of Wool Fibre Surface by Air Low-Temperature Plasma for an Application of Biopolymer

Effects of selected inorganic chemical activators on properties and hydration mechanism of high volume fly ash (HVFA) binders
(Elsevier Ltd., 2023)
Effects of Na2SO4, Na2CO3, and Na2SiO3 on setting time, compressive strength (up to 90 days), and hydration mechanism of binders with high volume (70 wt%, HVFA binders) of fly ash (FA) were investigated. Before chemical ...
GC-MS/MS and LC-MS/MS analysis followed by risk ranking of mepiquat and pyrethroids in coffee
(Academic Press Inc., 05-2024)
Pesticides used in coffee cultivation may remain behind and pose a risk to humans even after various processing stages of coffee beans (washing, drying, roasting, and grinding). In addition to pesticides applied to battle ...
