Abstract Traditional gas sensors are facing the challenge of low power consumption for future application in smart phones and wireless sensor platforms. To solve this problem, self‐powered rapidly developed recent years. However, all reported suffering from high limit detection (LOD) toward NO 2 gas. In work, a photovoltaic based on n‐MoS /p‐GaSe heterojunction is successfully prepared by mechanical exfoliation all‐dry transfer method. Under 405 nm visible light illumination, fabricated show...
Abstract The exfoliation of two naturally occurring van der Waals minerals, graphite and molybdenite, arouse an unprecedented level interest by the scientific community shaped a whole new field research: 2D materials research. Several years later, family that can be exfoliated to isolate keeps growing, but most them are synthetic. Interestingly, in nature, plenty minerals found with wide range chemical compositions crystal structures whose properties mostly unexplored so far. This...
The synergistic effects of triphasic cobalt-based nanoparticles andtheir superior structural features enable unprecedented bifunctional catalytic efficiency and durability.
Intelligent materials with adaptive response to external stimulation lay foundation integrate functional systems at the material level. Here, experimental observation and numerical simulation, we report a delicate nano-electro-mechanical-opto-system naturally embedded in individual multiwall tungsten disulfide nanotubes, which generates distinct form of in-plane van der Waals sliding ferroelectricity from unique combination superlubricity piezoelectricity. The enables programmable...
A dual-temperature zone CVD-assisted approach is developed for producing conductive porous metal catecholate MOF Cu<sub>3</sub>(HHTP)<sub>2</sub> nanowire arrays that are grown on the interface between a solid Cu foil and organic precursor.
Flexible electronics have enormous potential for applications that are not achievable in standard electronics. In particular, important technological advances been made terms of their performance characteristics and range applications, ranging from medical care, packaging, lighting signage, consumer electronics, alternative energy. this study, we develop a novel method fabricating flexible conductive carbon nanotube (CNT) films on various substrates. The fabricated CNT exhibited satisfactory...
For gas sensing applications, most of the reported two-dimensional (2D) materials are suffering from relatively low sensitivity and high limit detection (LOD) at room temperature. In this work, we selected rhenium disulfide (ReS2) nanosheets to fabricate ReS2 transistor-based sensors (RTGSs) with ultrahigh LOD toward nitrogen dioxide (NO2). The different thicknesses were prepared via mechanical exfoliation all-dry transfer method. Under 405 nm light illumination temperature (25 °C),...
Blue luminescent carbon quantum dots (CQDs) were prepared from cyanobacteria by a hydrothermal method. The PL yields of the obtained CQDs was 5.30%. Cyanobacteria-based dots/polyvinyl alcohol/nanocellulose composite films prepared, which could emit bright blue under UV light. FTIR characterization showed that had hydroxyl groups on surface and no new formed after combining three materials. photoluminescence (PL) spectra revealed emission excitation dependent. Studies water resistance...
We report the isolation of thin flakes cylindrite, a naturally occurring van der Waals superlattice, by means mechanical and liquid phase exfoliation. find that this material is heavily doped p-type semiconductor with narrow gap (<0.85 eV) intrinsic magnetic interactions are preserved even in exfoliated nanosheets. Due to its environmental stability high electrical conductivity, cylindrite can be an interesting alternative existing two-dimensional materials.
A flexible high-performance room temperature NH 3 sensor was fabricated using a PSS-rGO/PANI network, which synthesized via supramolecular assembly, controlled freeze-drying technology, and facile interfacial polymerization route.
Abstract The analysis of exhaled acetone is used as a noninvasive diagnosis for diabetes. Compared with traditional breath tools, chemiresistive gas sensors have attracted more attention real‐time monitoring, owing to the possibility integration and facile operation. However, most reported room‐temperature suffer from complicated preparation, costly raw materials, or relatively long response recovery time. In this work, naturally occurring layered mineral stibnite prepare Sb 2 S 3 by...
Abstract The dimensional limit of ferroelectricity has been long explored. critical contravention is that the downscaling leads to a loss polarization. This work demonstrates zero-dimensional by atomic sliding at restrained van der Waals interface crossed tungsten disufilde nanotubes. developed ferroelectric diode in this presents not only non-volatile resistive memory, but also programmable photovoltaic effect visible band. Benefiting from intrinsic limitation, allows electrical operation...
A smart surface with converse temperature-dependent (CTD) wettability was fabricated from an upper critical solution temperature-type (UCST-type) poly(acrylamide-co-acrylonitrile) (P(AAm-co-AN)) copolymer. The obtained exhibits a remarkable and reversible hydrophobic-hydrophilic transition depending on temperature high response rate. static water contact angle of the decreases 103° ± 2° to 60° 1° as increases 30 °C 80 °C. Further, UCST-type shows positive linear relationship between...
Aqueous zinc ion batteries (AZIBs) hold great potential in large scale, low-cost energy storage. Unfortunately, their development is limited by the poor performing cathode materials due to unstable structures and low capacities. Hence, we develop novel layer-by-layer stacked vanadium nitride nanocrystals/N-doped carbon hybrid nanosheets (VN/NC) as situ thermal conversion of pyrolyzing pentyl viologen intercalated V2O5. The combination a leaf-like morphology, nano structure crystals...
