This study investigates (ZnO)s with different surface features as vulcanization activators in unfilled SBR vulcanizates. ZnO is termed the best activator due to its fast reaction kinetics. A high release of ZnO into the environment harms marine ecosystems, and most ZnO production goes to the rubber sector; therefore, reducing ZnO amount is essential. Active, nano and functionalized ZnO compared to conventional ZnO in SBR matrix; concentration optimized based on curing, mechanical, physical, and dispersion analyses. The Arrhenius equation approximated the cure curve's kinetic constant and activation energy. Crosslink density measured by swelling experiment and solvent freezing point depression. Nano ZnO was used from 0.5 to 2phr, active ZnO from 1 to 4phr, and functionalized ZnO from 1 to 3phr compared to 5phr of conventional ZnO. The tensile strength of N1.5, F1.5, and A2 SBR increased by 5%, 26%, and 18% compared to C5SBR, whose elongation at break improved by 30%, 7%, and 23%. The data were analyzed using tukey HSD post hoc test. Regarding mechanical properties and curing characteristics, 2phr active, functionalized, and 1.5phr nano ZnO is analogous to 5phr conventional ZnO in an unfilled SBR matrix. The quantity of ZnO in rubber vulcanizates decreased successively by 60%, 60%, and 70%.

“…For vertical profiles such as the nanorods reported in this study, the surface roughness is evaluated from amplitude parameters, among which the root mean square (rms) roughness (Rq) is included. Rq is a measure of the standard deviation of the Z height [25] and its extrapolated value for SLTNR and SLTNR15 was 19.6 nm and 2.2 nm, respectively. A higher value of Rq for SLTNR can be explained by the fact that the nanostructures are not perfectly packed, as previously observed from SEM analyses (Fig.…”

“…Zn ions were substituted for Mg ions through the doping process, likely modifying the Zn-O bonds and A high surface roughness is essential for improving the sensing performance of fabricated EIS sensors. This is due to the increase in surface sites; consequently, further protonation and deprotonation will occur, increasing the potential at the oxide-electrolyte interface surface and resulting in higher sensitivity and linearity [61,[66][67][68][69][70]. However, Mg ions can easily form because Mg has a low electronegativity (X = 1.31).…”

For highly sensitive pH sensing, an electrolyte insulator semiconductor (EIS) device, based on ZnO nanorod-sensing membrane layers doped with magnesium, was proposed. ZnO nanorod samples prepared via a hydrothermal process with different Mg molar ratios (0–5%) were characterized to explore the impact of magnesium content on the structural and optical characteristics and sensing performance by X-ray diffraction analysis (XRD), atomic force microscopy (AFM), and photoluminescence (PL). The results indicated that the ZnO nanorods doped with 3% Mg had a high hydrogen ion sensitivity (83.77 mV/pH), linearity (96.06%), hysteresis (3 mV), and drift (0.218 mV/h) due to the improved crystalline quality and the surface hydroxyl group role of ZnO. In addition, the detection characteristics varied with the doping concentration and were suitable for developing biomedical detection applications with different detection elements.
