Manganese-doped zinc oxide hollow balls for chemiresistive sensing of acetone vapors

Mn-Modified ZnO Nanoflakes for Optimal Photoelectrochemical Performance Under Visible Light: Experimental Design and Theoretical Rationalization

“…The binding energy difference of 23 eV represents the Zn +2 charge state in Mn doped ZnO, consistent with the standard data on ZnO . The high resolution Mn 2p spectra have two peaks fitted at the binding energies of 640.3 and 656.0 eV attributed to Mn 2p 3/2 and Mn 2p 1/2 respectively Figure d shows a high resolution O 1s spectrum fitted into three peaks at the binding energies of 529.0, 530.4, and 531.7 eV, ascribed to lattice oxygen (O L ), oxygen vacancy (O v ), and chemisorbed oxygen (O c ), respectively .…”

Production of Si3N4porous beads via carbothermal reduction and nitridation technique

“…Fabrication of hollow/porous ceramic spheres is carried out via various processing techniques such as sacrificial core [47][48][49], spray drying [50][51][52][53], solvothermal process [54][55][56][57][58], nozzle reactor and microwave-assisted solvothermal synthesis [59], soft (templating vesicles, emulsions, micelles, etc.) and hard (templating silica, carbon, etc.)…”

Anticorrosion Performance and Application of a Mixed-Valence Mn0xMn2+0.05–xZn0.95O Solid Solution Induced by Magnetic Doping

“…The introduction of mixed-valence Mn ions can change the oxidation state, growth kinetics, amount of oxygen vacancies, and electronic properties of the materials. Most research studies have focused on the preparation, origin of magnetism, and crystal structure. , The studies of mixed-valence Mn-doping materials in the field of supercapacitors, spintronic devices, batteries, and gas sensors remain in the phase of theoretical analysis. Further exploration of pragmatic applications and mechanisms is demanded.…”
