DyTiO3 perovskite titanates exhibit ferri-magnetic ordering. Despite a nominal Ti valence of 3+, surface deviations to a more stable 4+ state disrupt this magnetic behavior for thin films. This valence evolution arises from short-range ordered interstitial oxygen planes and Ti-Dy cationic imbalance, inducing sufficient hole doping for a complete Ti4+...

Materials with specific work functions are key to the fabrication of a wide variety of efficient devices. This article presents a novel approach to work function tailoring using a monolayer buried within a material. The depth dependence of the layer on the work function can be exploited to produce a specific work function value, while retaining surface...

Combining smart feedback temperature control and lightweight aerogel insulation, a semispherical bilayer polyimide copper sandwich structure BiPI:Cu thin film origami heater is designed that generates a fast and even heating profile on food samples. The thin film heater fabricated by laser irradiation with a high degree of freedom in design can provide...

A novel precursor approach is presented for obtaining cobalt ferrite@carbon nanohorn bifunctional catalysts for zinc-air batteries, enabling simultaneous nitrogen doping and inorganic ferrite synthesis. The urea precursor approach is significant and may allow the synthesis of a wider variety of different mixed metal oxide catalysts. The nanohybrid...

A TiO2-based composite incorporating multi-walled carbon nanotubes (MWCNTs) and carbon nanodots (CNDs), with a total carbon content below 1 wt.% is developed. The optimized CND/MWCNT/TiO2 composite exhibits significant photocatalytic degradation of model pollutants under visible light irradiation. Detailed analysis attribute this enhanced performance...

A hierarchical structure of composite PPy nanopillar array/Ag nanoparticles is developed using polypyrrole nanopillar array as the matrix. Silver nanoparticles can be uniformly reduced and stably anchored onto the nanopillar array by the redox reaction in AgNO3 solution. The hierarchical structure displayed excellent sensing activity toward H2O2 and...
