The strong spin-orbit coupling and the broken inversion symmetry in monolayer transition metal dichalcogenides results in spin-valley coupled band structures. Such a band structure leads to novel applications in the fields of electronics and optoelectronics. Density functional theory calculations as well as optical ex…
Abstract Yolk–shell nanoreactors have received considerable interest for use in catalysis. However, the controlled synthesis of continuous crystalline shells without imperfections or cracks remains challenging. Here, a strategy for the synthesis of yolk–shell metal nanoparticles@covalent organic framework (MNPs@COF) n…
Metal-oxide nanoparticles (NPs) such as copper oxide (CuO) NPs offer promising perspectives for the development of novel agro-chemical formulations of pesticides and fertilizers. However, their potential impact on agro-ecosystem functioning still remains to be investigated. Here, we assessed the impact of CuO-NPs (0.1…
This letter reports the small-signal and large-signal performances at high drain voltage (VDS) ranging up to 60 V for a 0.5 μm gate length two-dimensional hole gas diamond metal-oxide-semiconductor field-effect transistor with a 100-nm-thick atomic-layer-deposited Al2O3film on a IIa-type polycrystalline diamond substr…
Abstract Nanocrystalline (NC) metals are stronger and more radiation-tolerant than their coarse-grained (CG) counterparts, but they often suffer from poor thermal stability as nanograins coarsen significantly when heated to 0.3 to 0.5 of their melting temperature (Tm). Here, we report an NC austenitic stainless steel…
Abstract Organic electrochemical transistors are bioelectronic devices that exploit the coupled nature of ionic and electronic fluxes to achieve superior transducing abilities compared to conventional organic field effect transistors. In particular, the operation of organic electrochemical transistors relies on a chan…
The simple binary compound SnSe has been reported as a robust thermoelectric material for energy conversion by showing strong anharmonicity and multiple electronic valence bands. Herein, we report a record-high average ZT value of ∼1.6 at 300–793 K with maximum ZT values ranging from 0.8 at 300 K to 2.1 at 793 K in p-…
Doping anions, such as fluorine, chlorine, sulfur, carbon or nitrogen elements, into the oxygen sites of metal oxides can alter the catalytic capability of metal oxide catalysts.
Abstract Photonic elastomers that can change colors like a chameleon have shown great promise in various applications. However, it still remains a challenge to produce artificial photonic elastomers with desired optical and mechanical properties. Here, the generation of metallosupramolecular polymer‐based photonic ela…
Carbon dots (CDs) are an emerging family of nanosystems displaying a range of fascinating properties. Broadly speaking, they can be described as small, surface-functionalized carbonaceous nanoparticles characterized by an intense and tunable fluorescence, a marked sensitivity to the environment and a range of interest…
Amorphous metal oxides (AMOs) have aroused great enthusiasm across multiple energy areas over recent years due to their unique properties, such as the intrinsic isotropy, versatility in compositions, absence of grain boundaries, defect distribution, flexible nature, etc. Here, the materials engineering of AMOs is syst…
Multifunctional nanoplatforms with special advantages in the diagnosis and treatment of cancer have been widely explored in nanomedicine. Herein, we synthesize two-dimensional core–shell nanocomposites (Ti 3 C 2 @Au) via a seed-growth method starting from the titanium carbide (Ti 3 C 2 ) nanosheets, a classical type o…
Abstract Light strongly interacts with structures that are of a similar scale to its wavelength, typically nanoscale features for light in the visible spectrum. However, the optical response of these nanostructures is usually fixed during the fabrication. Phase change materials offer a way to tune the properties of th…
We demonstrate excellent performance and durability at intermediate temperatures (500–650 °C) upon reversible operation of an electrochemical cell incorporating a proton-permeable, high-activity mixed conducting oxide as the air electrode, a highly proton-conductive and chemically stable perovskite oxide as the electr…
Abstract Heterostructures formed by stacking layered materials require atomically clean interfaces. However, contaminants are usually trapped between the layers, aggregating into randomly located blisters, incompatible with scalable fabrication processes. Here we report a process to remove blisters from fully formed h…
La presente tesis doctoral se centra en la obtención de nano-recubrimientos avanzados con propiedades antibacterianas que supongan un salto cualitativo en las prestaciones de las prótesis e implantes actuales. Se propone aportar un recubrimiento, en el rango nanométrico, como estrategia local para mitigar o reducir la…
