Cette etude considere l’endommagement des composites stratifies par une methode proposant la propagation d’un front de levelset epais (TLS : Thick LevelSet). Un modele elements finis est generalise pour etudier l’ensemble des dommages dans un composite : fissuration transverse dans la couche 90, delaminage en pointe d…
U radu je dan prikaz istraživanja celika API 5L X80 na osjetljivost prema pojavi hladnih pukotina uzrokovanih vodikom. Kod visokocvrstih celika, hladne pukotine se pojavljuju u metalu zavara i zoni utjecaja topline. Mehanizam djelovanja vodika je predmet mnogih istraživanja, i jos uvijek nije utvrđen univerzalni model…
NM 105, Ti02 (P25) could not be ignited as dust layer and dispersed in air as dust/air-mixture as well. This dust is not dust explosible and the burning behaviour corresponds to Burning Class 1 (no Ignition). The results have shown that the tested sample is thus not combustible at all, because it is already oxidized c…
The effect of strain path change during cold rolling on the evolution of microstructure, texture and hardness properties of high purity nickel (~99.7%) with extremely coarse starting grain size (~800 μm) has been studied in the present work. For this purpose two different rolling routes, namely, unidirectional cold ro…
One of the methods, used to prolong the time to or avoid corrosion initiation, is the utilisation of certain types of corrosion resistant reinforcement, which have higher resistance to corrosion than black steel reinforcement, and are less expensive than classical stainless steels, which makes their application as rei…

Hard and ultra-incompressible materials are of great interest due to their important applications in industry. A common route to design hard materials is combining transition metals with light and small covalent elements. Light elements such as carbon, oxygen, nitrogen and boron have been considered as good candidates…
This virtual Special Issue is dedicated to papers published in Food Additives and Contaminants from 2008 to date referring to the topic of Nanotechnology. The papers show not only the application potential of nanotechnology in the food and consumer products sector but also descirbe the challenges in the measurement of…
Composite solid electrolytes in the system (1-x)Pb(NO3)2 – x γ-Al2O3 were prepared by dispersing the nano particles of alumina (60 nm) by mechanical mixing in the presence of acetone at room temperature. Characterization was done by the X-Ray Diffractometry and ruled out the formation solid solutions of these composit…
Tetraphenylethene-containing polyynes with aggregation-induced emission characteristics are synthesized. The polymers are highly transparent in the entire visible spectral region and show high refractive indices (n = 1.7787–1.6543) in a wide wavelength region of 400–1700 nm.

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
In this work we have measured the natural radiation content of the building materials (raw and manufactured) using HPGe detector. The intensities of a-ray emitted by radioactive nuclides present in the samples were determined. Efficiency of the detector at different energies was determined using standard sources, so t…
Unnecessary pesticide use not only increases human exposure but also increases potential impact on ground water quality. Consumers using IPM practices and compost as a soil amendment can decrease pesticide use. Compost can improve growing conditions for plants (plants that grow well are less susceptible to insect pest…
Korozijski postojani materijali koriste se kako u svakodnevnom životu, tako i u svim granama industrije. Sve više se koriste i u građevinarstvu, različitim područjima strojarstva, brodogradnji, itd. Jedna od najvažnijih skupina konstrukcijskih postojanih materijala jesu tzv. "nehrđajući čelici". Upravo zahvaljujući ra…
With the purpose of durability evaluation of the textile materials in conditions of use, the paper investigates the quality of three white knitted fabrics, of different structural and construction characteristics, intended for shirts. In order to transfer readable information, on each of the fabrics were printed two Q…
U radu se ispituju svojstva zaštite od korozije ukopanih cjevovoda. U teorijskom dijelu opisane su vrste korozijskih oštećenja metalnih materijala, problematika korozije ukopanih konstrukcija, metode zaštite od korozije, a posebno zaštita viskozno – elastičnom prevlakom. U eksperimentalnom dijelu rada ispitano je pona…
Proteases are industrially important enzymes and have niche applications in diagnostic kits that use cell lysis and thereby require high resistance towards chaotropic salts and detergents, such as guanidinium chloride (GdmCl) and sodium dodecylsulfate (SDS). Subtilisin E, a well-studied serine protease, was selected t…
Los nanocompuestos de metales con halloysita, son materiales potencialmente utiles en diversos campos de la medicina y la biologia, por lo que son de gran interes actual en investigacion y desarrollo. En este articulo se reporta la sintesis en el interior de los nanotubos naturales de halloysita de nanoparticulas de o…
The investigation of composition dependence of various properties of chalcogenide glasses has been increased in recent years. Since reversible switching phenomenon in certain types of chalcogenide glasses was first reported, a lot of attention has been given to characterization and improvement of the properties of cha…
