Abstract:
Cu-Ce(Mn)-Al oxide catalysts to NO removal in the broad temperature range were synthesized and tested. The precursor of copper aluminium spinel was obtained with the coprecipitation method. By this method, Cu–Al spinels with various amounts of manganese and cerium were synthesized as well. These oxides crystallized in the structure of inverse spinel; however, Ce doping caused the appearance of additional CeO2 phase as determined by XRD. The samples were mesoporous solids with moderate surface area and porosity measured by low temperature sorption of nitrogen. The addition of another metal to C

The sol-gel auto-combustion method was used to synthesize copper nanoferrite and activated carbon-copper nanoferrite composite. The stoichiometric chemical proportions of Cu, Fe, and O were confirmed by EDX, and the porosity was checked by SEM of synthesized specimens. The spinel phase copper nanoferrite was confirmed by XRD. The octahedral and tetrahedral force constants were calculated using FTIR spectra of pristine and activated carbon–copper nanoferrite composite. The experiments of Methylene blue’s degradation in sunlight with H2O2 and loading of synthesized specimens were carried out. Th

Abstract:
Selective catalytic reduction of NO with CO (CO-SCR) has been suggested as an attractive and promising technology for removing NO and CO simultaneously from flue gas. Manganese-copper spinels are a promising CO−SCR material because of the high stability and redox properties of the spinel structure. Here, we synthesized CuxMn3−xO4 spinel by a citrate-based modified pechini method combining CuO and MnOx, controlling the molar Cu/Mn concentrations. All the samples were characterized by SEM, EDX, XRD, TEM, H2−TPR, XPS and nitrogen adsorption measurements. The Cu1.5Mn1.5O4 catalyst exhibits 100% NO

Spinel copper ferrite nanoparticles have wide spread technological applications. Polycrystalline copper ferrite nanoparticles is prepared by sonochemical method. The structural property is investigated by X-ray diffraction study, which reveals cubic spinel structure of copper ferrite NPs with average crystalline size of 20 nm. The temperature variation of DC conductivity of copper ferrite nanoparticles is studied. The conductivity is observed to increase with temperature which implies semiconducting nature of copper ferrite. The Mott study reveals that conduction process is three dimensional i

Abstract:
CuO–Al2O3 catalysts containing various amounts of copper oxide have been prepared by precipitation. The phase changes were studied by X-ray diffraction. The results obtained revealed that the thermal treatment of solid CuO–Al2O3 at 700 °C produced only crystalline CuO. Heating to 900 °C led to the formation of copper alumina spinel together with unreacted CuO and γ-Al2O3. The spinel content was found to increase with increasing copper content. Nitrogen adsorption–desorption isotherms on the calcined samples have been measured. Surface areas have been calculated and the pore structure analysed.

Cobalt and cobalt-manganese spinel ferrites have magnetostrictive properties suitable for application in magneto-electric and magneto-mechanical transducers. In this work, copper-substituted ferrites of these compositions were processed by means of the ceramic method and their sinterabilities were evaluated by dilatometric thermal analyses. The results obtained suggest that copper affects the solid-state reactions for the spinel formation and lowers the required sintering temperature for the ferrites. However, the densification obtained with sintering of the copper-substituted ferrites at 950o

Abstract:
The impact of metal ion substitution on the characteristics of cobalt ferrite nanoparticles is investigated in this work. Sol-gel auto-combustion was used to insert copper (Cu), nickel (Ni), and zinc (Zn) into the spinel lattice. The goal of the study is to comprehend the effects of these substitutions (CuCoFe, NiCoFe, and ZnCoFe) on the magnetic, spectral, and structural properties of the resultant nanoparticles. For every synthetic sample, the successful development of a cubic spinel phase has been confirmed by X-ray diffraction examination. The estimated crystallographic size is roughly 25

Abstract:
Abstract Binary spinel-type metal oxides (AB2O4) semiconductors, including ferrites (AFe2O4), are attractive photocatalysts thanks to their excellent visible light response and good photochemical activity and stability for the photodegradation of organic pollutants. Currently, their synthesis proceeds via conventional chemical routes that follow rather tedious protocols and the final preparations consist in nano-powders, a form that is not exempt of EHS (Environment, health and safety) risks along their handling. From an industry perspective, it is desirable to dispose of an efficient and pref

В статье представлены результаты рамановского анализа химического и структурного состава фрагментов импортного глазурованного кувшина из раскопок в Муроме. Исследованы кроющая глазурь и пигменты, использованные при его росписи. Полученные результаты позволяют объективно определить место и время изготовления находок (Изник, Турция, XVI в.). Выявлены характерные особенности такой керамики, которые могут позволить атрибутировать находки ее фрагментов на основе материалов, использованных в красках: уваровита в оливково-зеленом линейном орнаменте, силиката кобальта со структурой оливина в синем фон

Introduction: Copper deficiency is a rare disease that can present with a wide variety of symptoms, with myelopathy as the most common neurological presentation. The clinical features are characterized by sensory ataxia, spasticity and sensory-motor neuropathy. The risk factor that has the most impact is previous gastrointestinal surgery, but a large part of cases remain without a determined cause. The aim to present a case of combined subacute medullary degeneration secondary to copper deficiency with good response to treatment by reviewing the patient’s medical record. Case report: Male, 47-

Context: The Spinal Muscular Atrophy (SMA) is a genetic disease responsible for degeneration of the motor neurons of the spinal cord and the motor nucleus of the cranial nerves. Case report: Male patient, 32 years old, 6 years ago presented proximal weakness in lower limbs and distal weakness in upper limbs with progressive worsening and episodes of dyspnea on physical exercise, without dysphagia and dysarthria. The lower limbs showed grade of power of 3/5 in the proximal muscle group and 4/5 in the distal muscle group. On the upper limbs the grade of power was 4/5 in both proximal and distal

Abstract:
Abstract Laser keyhole welding of dissimilar metals has been widely used in industrial applications. One critical challenge for this process is the formation of intermetallic compounds (IMCs) that undermine the electrical and mechanical properties of the joints. Compared with the commonly used linear contours, welding with spiral contours can provide larger areas of joining and hence higher allowable loading. This can be particularly useful for certain applications. In this research, laser welding experiments with different spiral contours were performed, and the chemical composition, microstr

Mineral resources of Baffin Island include iron (Mary River), diamonds, carbonate-hosted zinc and lead (Nanisivik), nickel, copper, platinum group elements, uranium, thorium, gemstones (sapphire, spinel, lapis lazuli), carving stone, and coal. Iron deposits include the Mary River No. 1 to 4 deposits of northern Baffin Island, which came into production in 2015 and contain 586 Mt grading 66% Fe. The Mesoproterozoic Borden Basin hosts the Nanisivik deposit, mined between 1976 and 2002; this is a Mississippi Valley-type deposit and contains 9.0% Zn, 0.7% Pb, and 41 ppm Ag.

Abstract:
Most, if not all advanced economies have suffered gravely from the 2008 global financial crisis. Growth, productivity, real income and consumption have plunged and inequality, and in some cases poverty, spiked. Some countries, like Germany and Australia, were better able to cope with the consequences but austerity has taken its toll even on the strongest economies. The UK is no exception and the more recent period of economic recovery might be halted or even reversed by the political, economic, and policy uncertainty created by the Brexit referendum. This uncertainty related risk to growth cou
