A novel hydrophobic rare earth‐based aluminum hypophosphite (AHP) was prepared using rare earth aluminate coupling agent (REA) in a ball mill with a one‐step mechanochemistry method, and used as flame retardant for epoxy resin. It has been found that RaAHP‐4 (AHP was modified by 4 wt% REA) exhibited excellent hydrophobic properties with the water contact angle of 94.58°. The effect of RaAHP‐2 (AHP was modified by 2 wt% REA) and RaAHP‐4 on the flame retardancy, thermal stability, and hydrophobic properties of EP/6RaAHP‐2 and EP/6RaAHP‐4 composites were investigated. It has been found RaAHP‐2 and RaAHP‐4 can significantly improve the flame retardant performance of EP/6RaAHP‐2 and EP/6RaAHP‐4 composites. And the peak heat release rate (PHRR) and total heat release (THR) values of EP/6RaAHP‐4 were reduced by 50.44% and 35.59% compared with pure EP, respectively. Moreover, the maximum peak value of CO production rate from EP/6RaAHP‐4 decreased by 62.64% compared with that from EP/6AHP. The excellent flame retardant effect of EP/6RaAHP‐4 composites was obtained because RaAHP‐4 changed the formation of the char residue layer during the combustion process. In comparison, the compactness, expansion degree, and carbonization quality of the char residue layer from the samples with RaAHP‐2 or RaAHP‐4 have been significantly improved, which acted as a valuable barrier for heat and mass transfer. The above results showed that the one‐step synthesis method had high potential application in the large‐scale production of hydrophobic AHP.

“…Lee et al proposed the insertion of Ti in the Y 2 O 3 dielectrics to achieve a lower leakage current, a higher capacitance value, a lower electron trapping rate, and enhanced the structural integrity of Y 2 O 3 film on a Si substrate. 27 A considerable amount of research has been dedicated to the deposition of Y 2 O 3 film by different technologies, such as atomic layer deposition (ALD), 28 radio-frequency sputtering, 29 metal-organic chemicalvapor-deposition (MOCVD), 30 and e-gun evaporation. 31 As compared to these methods, the sol-gel method has a number of attractive features which include control composition of binary-tertiary oxide, atomic level of mixing, economically profitable, low processing temperature, and low synthesis time.…”

The present study was designed to determine the effect of annealing temperature on the sol-gel synthesized YTixOy electroceramic sensing membrane on silicon substrate as an electrolyte-insulator-semiconductor (EIS) based pH sensor. We observed that the YTixOy sensing membranes after annealing at high temperatures (700, 800 and 900°C) modify the structural feature, sensing characteristic and reliability. X-ray diffraction, atomic force microscopy and X-ray photoelectron spectroscopy have been used to reveal the film microstructure, surface morphology and chemical composition, respectively. As compared to the other annealed samples, the YTixOy sensing membrane annealed at 800°C manifested the highest sensitivity (58.52 mV per unit of pH), lowest hysteresis voltage (2.6 mV), and lowest drift rate (0.10 mV/h). These results demonstrate that the film annealed at 800°C suppresses the formation of oxygen vacancy and intrinsic defect forming a stoichiometric YTixOy sensing film.

Successive Gradient Internal Electric Field Strategy Toward Dendrite‐Free Zinc Metal Anode

With the rapidly increasing demand for grid‐scale energy storage systems, rechargeable aqueous zinc ion batteries (ZIBs) are capturing attention as a highly promising technology with low cost and high safety. Nevertheless, rampant dendrite growth, hydrogen evolution reaction (HER), and corrosion of the zinc anode have dramatically impacted their practical application. Here, a self‐supported modified layer with ultrafine high‐entropy nanoparticles (2 nm) as the zincophilic sites is realized to modify the Zn anode for the first time. High‐entropy materials with unique continuously distributed potential gaps significantly reduce the activation energy of multi‐electron reactions and modulate ion transport during zinc deposition. Moreover, thanks to the hydrophobic properties and effective desolventizing ability of the ultrafine high‐entropy nanomaterial, the unfavorable side reactions of the zinc anode are prevented to promote the zinc deposition process. As a result, stable cycling of 3500 h at 1 mA cm−2 and 600 h at a high current density of 10 mA cm−2 is achieved. Coin cells and flexible pouch cells assembled with KMO and NH4V4O10 cathodes also demonstrate promoted electrochemical performance. The dual effects of accelerating and homogenizing mechanisms in high‐entropy materials provide a new strategy for stabilizing zinc metal anodes.
