Summary: The study investigated the effect of chromium doping in cobalt ferrites at the nano scale, revealing a decrease in lattice constant and crystalline size as well as a decrease in electron density inside the unit cell due to Cr doping. Infrared analysis showed two absorption bands and the electrical properties exhibited semiconductor behavior. Magnetic properties demonstrated ferrimagnetic ordering with a decrease in coercivity as a result of iron substitution with chromium.

Summary: Spinel ferrites with the compositional formula Ni0.8Zn0.2Fe2-xDyxO4 (x = 0, 0.004, 0.008, 0.012, 0.016) were prepared using the sol-gel method. The X-ray diffraction measurements confirmed the cubic spinel structure of the samples. Morphological analysis revealed spherical shaped particles. Thermogravimetric analysis showed the temperature changes and energy dispersive X-ray spectroscopy confirmed the elemental composition. Fourier-transform infrared spectroscopy revealed the various bonds present in the compounds. The UV-vis absorption spectrum indicated energy gap values, which decreased slightly with increased Dy concentration. Raman spectroscopy studied the crystal distortion and phases, and magnetic measurements observed the effect of Dy doping on magnetic properties.

Summary: In this study, sulfur-doped bimetallic cobalt tungstate porous nanospheres were developed via a single-step, ascendable bottom-up approach for efficient hybrid supercapacitors. The sulfur-doped CoWO4 nanospheres exhibited enhanced electrical conductivity, porosity, and openness for ion migration, resulting in specific capacity of 248.5 mA h g(-1), specific capacitance of 177.25 F g(-1), and specific energy of 63.41 Wh kg(-1) with excellent cycling stability and rate capability. The superior supercapacitive performance of sulfur-doped CoWO4 nanospheres is attributed to the sulfur doping and bottom-up fabrication of the electrode materials.

Summary: The Sb-doped SnO2-SiO2 film shows reduced crystallinity with Sb doping, exhibiting M-shaped changes in lattice parameters with increasing Sb concentration. Nanoparticle size decreases and then increases with Sb doping levels above 6 mol%. Additionally, the transmittance of the glass substrate coated with this film decreases, while resistance and dust removal performance exhibit complex changes with varying Sb concentrations. At 12 mol% Sb doping, the film exhibits minimal resistance and a 64% dust removal performance.

Summary: Cancer is a leading cause of death globally, and early diagnosis is crucial for improving patient survival. Conventional cancer detection methods are limited for early detection, but advancements in molecular technology have enabled the use of biosensors to identify cancer biomarkers for diagnosis and prognosis. Photoelectrochemical (PEC) biosensors show potential in early cancer detection with improved selectivity and sensitivity compared to conventional methods. The use of 2D carbon nanomaterials as electrode platforms in PEC biosensors is gaining interest due to their high surface area and ease of modification.
