Point-of-use (POU) devices with satisfactory lead (Pb2+) removal performance are urgently needed in response to recent outbreaks of contamination drinking water. This study experimentally demonstrated the excellent capability two-dimensional (2D) MoS2 nanosheets aqueous form and as part a layer-stacked membrane. Among all materials ever reported literature, exhibit highest adsorption capacity (740 mg/g), strongest selectivity/affinity toward Pb2+ distribution coefficient Kd that is orders...
Abstract Infrared (IR) detection at 1300–1650 nm (optical communication waveband) is of great significance due to its wide range applications in commerce and military. Three dimensional (3D) topological insulator (TI) Bi 2 Se 3 considered a promising candidate toward high‐performance IR applications. Nevertheless, the devices based on thin films are rarely reported. Here, 3D TI /MoO film heterojunction photodetector shown that possesses ultrahigh responsivity ( R i ), external quantum...
The intriguing carrier dynamics in graphene heterojunctions have stimulated great interest modulating the optoelectronic features to realize high-performance photodetectors. However, for most phototransistors, photoresponse characteristics are modulated with an electrical gate or a static field. In this paper, we demonstrate graphene/C60/pentacene vertical phototransistor tune both time and photocurrent based on light modulation. By exploiting power-dependent multiple states of photocurrent,...
Aggregation significantly influences the transport, transformation, and bioavailability of engineered nanomaterials. Two-dimensional MoS2 nanosheets are one most well-studied transition-metal dichalcogenide Nonetheless, aggregation behavior this material under environmental conditions is not well understood. Here, we investigated single-layer (SL-MoS2) a variety conditions. Trends in SL-MoS2 consistent with classical Derjaguin-Landau-Verwey-Overbeek (DLVO) colloidal theory, critical...
High responsivity, fast response time, ultra-wide detection spectrum are pursuing goals for state-of-art photodetectors. Cd3As2, as a three-dimensional (3D) Dirac semimetal, has zero bandgap, high light absorption rate in broad spectral region, and higher mobility than graphene at room temperature. However, photoconductive detectors based Cd3As2 suffer low quantum efficiency due to the absence of built-in field. Here, nanoplate/multilayer MoS2 heterojunction photodetector was fabricated...
The aggregation–redispersion behavior of nanomaterials determines their transport, transformation, and toxicity, which could be largely influenced by the ubiquitous natural organic matter (NOM). Nonetheless, interaction mechanisms two-dimensional (2D) MoS2 NOM subsequent influences on redispersion are not well understood. Herein, we investigated single-layer (SL-MoS2) nanosheets as Suwannee River (SRNOM). It was found that SRNOM played a decisive role 2D varied distinctly from 3D...
Carbon allotropes have been widely investigated in photoelectric applications, including single-walled carbon nanotubes (SWCNT), graphene, and C60, due to their high carrier mobility superior optical properties. Unfortunately, it is proved that the device only by one type of alone could barely exhibit performance both near-infrared (NIR) range visible-light (VL) range. Here, we demonstrate a broadband photodetector based on all-carbon materials (C60/graphene/SWCNT) which possesses an...

Tunable complementary split ring resonators (CSRRs) based on monolayer graphene are presented in terahertz regime. By applying different gate voltage, the Fermi level and optical conductivity of pattern can be changed. Here, we employ a numerical simulation to study interaction light with CSRRs. The results indicate that extinction transmission becomes stronger, resonance frequency presents blue shift higher pattern. Three pronounced resonant peaks appear which modulated dynamically range...
