Calcium manganate Ruddlesden-Popper phases Ca2MnO4-delta were prepared by soft chemistry and treated with acid to extract a part of the calcium ions. Combined structural, morphological and spectroscopic analyses by XRD,SEM/EDX, TEM and Raman revealed an amorphization of the treated surface with a preserved inner cryst…
In the modern, global and domestic practice is widespread process of reconstruction of industrial buildings and structures in objects civilian purposes. In the scientific and technical literature, this process is called — revitalization of industrial buildings. Revitalization (from Lat. Re — restoration, vita — life)…
Supercapacitor electrodes are often made of porous carbon materials such as activated carbon, but also graphene was frequently used as active electrode material. Graphene can be produced by mechani ...

Metamaterials exhibit unique optical resonance characteristics which permit precise engineering of energy pathways within a device. The ability of plasmonic nanostructures to guide electromagnetism offers a platform to reduce global dependence on fossil fuels by harvesting waste heat, which comprises 60% of generated…
Field of carbon/carbon composite materials still offers opportunities for exploration and invention of new production processes or particular compounds as carbon sources from which worth final product may be derived or else another branch of utilization introduced.In former research work anthracene substance was deter…
In this work, plasma enhanced atomic layer deposited (PE-ALD) samples were prepared at substrate temperatures in the range between room temperature (RT) and 200 °C and investigated by capacitance–voltage and conductance–voltage recordings. The measurements are compared to standard thermal atomic layer deposition (T-AL…
During the composite component design process, and at the manufacturing stage, there is a requirement to understand the effect of defects in terms of their 'knock-down' in the structural performance. The result would be justifiably lighter designs, a better-informed concession process for manufacturing defects and imp…
Ферриты BaFe12O19, SrFe12O19 со структурой минерала магнетоплюмбита являются одноосными ферримагнетиками, имеют большую величину коэрцитивной силы (Hc), хорошую химическую стабильность, низкую цену и широко используются для изготовления постоянных магнитов. До середины 90-х годов XX века улучшение магнитных свойств по…

When mineral wool is heated to fire temperatures, heat is developed inside the material. Experiments have shown that although the mineral wool is externally heated, the temperatures inside the material rises well above the temperatures registered on the surface of the material. This phenomenon is a result of two exoth…
This study investigated the properties of green banana films as potential packaging films. Banana films from green banana (with concentrations 2-10% w/w) were prepared by using casting method. This study investigated the properties of green banana films as potential packaging films. Banana films from green banana (wit…
Monoclinic form of BiPO4 phase has been prepared based on the reaction of Bi3+ and PO43− ions in ethylene glycol medium at 185°C. Monoclinic BiPO4 forms random solid solutions with lanthanide phosphates having monoclinic structure as confirmed by XRD and 31P solid state nuclear magnetic resonance studies.

In the article the analysis of dependence of surface-tension of iron- sulphur fusions is executed from the concentration of sulphur. Data of superficial properties of fusions of Fe-S, and also influence of sulphur, are investigational and presented on superficial properties of metallurgical fusion
В роботі представлені результати експериментальних досліджень кристалічної структури і елект-роопору в тришарових нанокристалічних плівках Co / Ag / Fe та Co / Cu / Fe. Показано, що всі відпа-лені за температури 700 К зразки з dCu,Ag > 5 нм є трифазними (ГЦК-Со, ГЦК-Ag або ГЦК-Cu, ОЦК-Fe). Експериментально отримана за…
V diplomski nalogi sem ugotavljal, kaksen vpliv ima EAF C žlindra na fizikalno-mehanske lastnosti betona. V ta namen sem izdelal dve betonski mesanici po enaki recepturi, pri cemer sem uporabil razlicna agregata. V prvi mesanici sem uporabil žlindrin, v drugi pa drobljen apnencev agregat. Najprej sem preizkusal lastno…

Collections de BAnQ (M40 COF).En 1863, la Commission géologique du Canada fait paraître à Montréal un ouvrage scientifique très attendu et qui sera sans doute l’œuv…
In this study cellulose materials were pre-treated with cationic agent in order to obtain more reactive supports for in situ synthesis of alumosilicate microprous compounds. Cation-generating polyammonium agent was applied by padding of cotton fabric with hydrogel. The synthesis of aluminosilicate microporous compound…
