Technological applications of novel metastable materials are frequently inhibited by abundant defects residing in these materials. Using first-principles methods, we investigate the defect thermodynamics and phase segregation in the technologically important metastable alloy GaAsBi. Our calculations predict defect ene…
A change of van der Waals stacking occurs spontaneously at 90 K in a cluster magnet.
Thin films: How to overachieve at underpotentials The deposition of atomically thin metal films can be predicted with a comprehensive model incorporating realistic environmental factors. Nanomaterials used as catalysts and sensors are often produced by the spontaneous attachment of metal ions onto inert metal surfaces…
Taking advantage of the large electron escape depth of soft x-ray angle resolved photoemission spectroscopy, we report electronic structure measurements of (111)-oriented [LaNiO3/LaMnO3] superlattices and LaNiO3 epitaxial films. For thin films, we observe a 3D Fermi surface with an electron pocket at the Brillouin zon…
We report the controllable growth and the intriguing transport behavior of high-spin-polarization epitaxial L21-Co2MnAl films, which exhibit a low-temperature (T) resistivity upturn with pronounced T1/2 dependence, close relevance to structural disorder, and robust independence of magnetic fields. The resistivity uptu…
We present a synthesis/processing method for fabricating ferrimagnetic insulator (Bi-doped yttrium iron garnet) thin films with tunable magnetic anisotropy. Since the desired magnetic properties rely on controllable thickness and successful doping, we pay attention to the entire synthesis/processing procedure (nanopow…
The key elements in the mechanism of the formic acid oxidation reaction on platinum have been completely elucidated, not only for the direct path through an active intermediate, but also for the CO formation route.
Efficient NIR-to-blue photon upconversion was realized for the first time by exploiting sensitizer S–T transition and achieved the largest anti-Stokes shift of 0.97 eV.
Due to “CO-Promoted O <sub>2</sub> Activation”, the termolecular Eley–Rideal (TER) mechanism is the most relevant one for CO oxidation over the SAC, Ag <sub>1</sub> /BN.
Hierarchical CuCo <sub>2</sub> O <sub>4</sub> @NiO core–shell nanotree arrays on porous nickel foam substrates are synthesized <italic>via</italic> a simple hydrothermal approach and further investigated as electrode materials for supercapacitors.
N-CQDs are synthesized using a green, environmentally friendly microplasma and employed in solar cells, achieving a <italic>V</italic> <sub>OC</sub> of 1.8 V.
CuO/NiO hole selective layer: one step closer to fully earth abundant, low-cost and efficient Cu <sub>2</sub> O photocathodes for H <sub>2</sub> production.
Correction for 'Thickness-dependent in-plane thermal conductivity of suspended MoS2 grown by chemical vapor deposition' by Jung Jun Bae et al., Nanoscale, 2017, 9, 2541-2547.
The construction of energy-favorable Mg–Zr–H interfaces provides channels to control hydrogen transfer to realize fast storage in Mg-based materials.
Understanding the photoexcited carrier-relaxation actions in ultrasmall black phosphorus quantum dots (BPQDs) will play a crucial role in the fields of electronics and optoelectronics. Herein, we report the ultraviolet (UV) saturable absorption and ultrafast photoexcited carrier-relaxation dynamics of BPQDs. The ultra…
A novel GQD-complex was designed as a promising theranostic agent for the treatment of HER2-positive breast cancer.
The elastic soft (PVA/PPy) <sub>(−)</sub> //CNTs <sub>(+)</sub> supercapacitor is first designed who exhibits fascinating mechanical properties and realizes a high working voltage.
Sensitive turn-off mode fluorescence sensing for Fe <sup>3+</sup> based polyimide bond linked COFs.
Two fluorescein-based chemosensors have been developed. They exhibited rapid and selective detection of 2,4,6-trinitrophenol (TNP) via fluorescence quenching both in ethanol and water solution when excited by visible light.
