Encapsulation of NiCo2O4 in nitrogen-doped reduced graphene oxide for sodium ion capacitors
Sodium-ion capacitors are considered as promising energy storage devices for medium/large-scale energy storage applications including electric vehicles (EVs) and smart grid technologies because of their high energy/power densities and long cycle life ...

Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Substituted Bi3.5Mg1.8Nb2.7O13.8 pyrochlores with transition metals (Zn, Ni and Cd): Doping mechanism, structure and electrical properties [PDF]
The influence of transition metals (Zn, Cd and Ni) on bismuth magnesium niobate (Bi3.5Mg1.8Nb2.7O13.8, BMN) pyrochlores was investigated. Considering the difference in their ionic radii, Cd was postulated to substitute Mg at the eight-fold coordinated A ...

The review of current status of literature on electrochemical capacitors is presented. The electrochemical capacitors are subdivided into filmic (dielcctrical), electrolytic and supercapacitors (SC). The last are subdivided into double layer capacitors (DLC), pseudocapacitors (PC) and hybrid capacitors (HC).

Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.
