Abstract Stabilized α‐Ni(OH) 2 nanoparticle modified fluorine doped tin oxide (FTO) electrodes were shown to be excellent glucose amperometric FIA sensors exhibiting high specific sensitivity (446 µA mM −1 cm −2 ), low limit of detection (3 µM) and analytical frequency (128 analyses/hour). The constituted by ∼20 nm nanoparticles the was only slightly improved in hydrodynamic as compared diffusional conditions reflecting enhanced surface area moderate heterogeneous electron transfer rates at...
Systems comprising anti-inflammatory sulindac intercalated into biocompatible layered double hydroxides nanovehicles were isolated through one pot synthetic method and showed high crystallinity curled or scrolled particles.
Improving the charge capacity, electrochemical reversibility and stability of anode materials are main challenges for development Ni-based rechargeable batteries devices. The combination cobalt, as additive, electrode material nanostructuration revealed a very promising approach this purpose. new α-NiCo mixed hydroxide based electrodes exhibited high specific charge/discharge capacity (355–714 C g−1) outstanding structural stability, withstanding up to 700 redox cycles without any...
Nickel hydroxide can provide an outstanding cathode material in alkaline secondary batteries, however the progressive decrease of charge capacity as a function number oxidation/reduction cycles is challenging problem to be solved. New improvements on electrochemical properties electrode materials achieved by exploiting much better performance alpha-nickel hydroxide. Such were obtained stable form sol-gel method and characterized thermogravimetric analyses, UV-Vis spectroscopy, X-ray...
Intercalation of deprotonated folic acid (FA; vitamin B9) is great interest for nutraceutical and cosmeceutical purposes. Although some studies have already reported the intercalation divalent (HFol2- ) or trivalent (Fol3- folate anions into layered double hydroxides (LDH), structure, spectroscopic, thermal behavior such hybrid materials still need to be better understood. This work revisited synthesis LDH constituted by M2+/Al3+ (M2+ = Mg Zn) intercalated with HFol2- Fol3- . Insights...
