We study the effect of the synthesis method on the structural and magnetic properties of La0.7Ca0.2Ba0.1Mn03. The samples were synthesized by coprecipitation and solution combustion methods. X-ray diffraction and scanning electron microscopy were performed to investigate the crystallographic structure, showing that both methods produced La0.7Ca0.2B...

In order to improve the corrosion resistance of welded joints, X90 pipeline steel joints were subjected to post-weld heat treatment at 610 °C, 640 °C, and 670 °C (holding time was 1 h). Through electrochemical corrosion and full immersion corrosion experiments, the corrosion resistance of welded joints under various conditions was tested, and the s...

Environmental pollution seriously affects the survival of human beings. Semiconductor photocatalysis technology is considered to be one of the most effective ways to solve environmental pollution and energy shortage. The high degradation efficiency of nanometric photocatalysts has attracted extensive attention, but the photocatalysts are difficult ...

Vacuum electron beam welding was applied to a 50 mm-thick TA15 titanium alloy plate. Microstructure observation and microhardness testing were performed. Meanwhile, the residual stress on the surface at different distances from the weld centre was measured via the hole drilling method. A finite element model for electron beam welding of the TA15 ti...

MnFe2O4 nanoparticles were synthesized using the co-precipitation method with a wide range of molar concentrations of sodium hydroxide 0.76 M−3.0 M. X-ray diffraction, field effect scanning electron microscopy, transmission electron microscopy, and vibrating sample magne-tometry were employed to characterise the structural, morphological, and magne...

Sn1−x Fe x O2 (x = 0, 1, 2, 3, and 4 %) of the diamagnetic/ferromagnetic phase were synthesized by the conventional hydrothermal method. X-ray diffraction spectra confirm that all the samples have a tetragonal structure. Electronic distribution over the unit cell of Sn1−x Fe x O2 showed the dependence of electronic density on the x. The crystallite...

A controlled and sustained release of drugs is much more desirable and beneficial when dealing with cancer, as such drugs also harm normal cells. Available anticancer drugs used in chemotherapy are associated with severe side effects due to high dosage requirements. Electrospun nanofibers have an extensive surface area, controllable pore size, and ...

Utilisation of templates facilitates the synthesis of titania samples with improved physico-chemical properties. When biomaterials are utilised as templates in the creation of inorganic materials, they can lead to constructed mesostructures via cost-effective and environmentally friendly synthetic pathways. Based on this context, the goal of this s...

In this study, poly(2-ethyl aniline)/graphene composites were prepared by a mechanochemical method, through in-situ polymerization of 2-ethyl aniline in the presence of graphene at different concentrations. Vickers microhardness, elastic modulus and electrical conductivity measurements were carried out as a function of the graphene concentration in...

Bone disorders and conditions have been increasing at an alarming rate all over the world, especially in niches where increased obesity and poor physical activity have been prevailing. Synthetic nanohydroxyapatite (HAp) is one of the remedies to reconstruct bone formation. Its rate of dissolution and compatibility is in the moderately acceptable ra...
