This work reports the wavelength- and pulse-duration-dependent nonlinear optical properties of exfoliated black phosphorus (BP). We found that BP nanosheets exhibit better saturable absorption response in visible range than near-infrared under 6 ns pulse excitation 340 fs excitation. In addition, we propose optically induced transparency limiting dispersions mainly originate from competition between scattering.
Abstract The demand for an ultrabroad optical material with a bandgap tunable from zero to at least 1–2 eV has been one of the driving forces exploring new 2D materials since emergence graphene, transition metal dichalcogenides, and black phosphorus. As ultra‐broadband energy ranging 0 1.2 eV, PtSe 2 shows much better air stability than its analogue, phosphorous. In this work, superior nonlinear performance ultrafast dynamics layered , signatures semiconductor semimetal are systematically...
The incorporation of green and sustainable nanomaterials in pesticide formation is an effective method to lower the use conventional pesticides without adverse effects on productivity. Here Pickering emulsions stabilized by halloysite nanotubes (HNTs) were developed for low cost, less environmental pollution, toxic effects, better emulsion stability. HNTs added chlorantraniliprole (CAP) emulsions, good stability was exhibited due adsorption aggregation at interface CAP oil droplets, forming...
Discovering stabilizers that protect phosphorene from oxidative degradation is critically required for dispersion processing of black phosphorus (BP). It equally important to also find environmentally friendly, low-cost, and practical exfoliating media. Herein, we demonstrate the yield remarkably stable by coating with a polymer shield nanosheets reaction water air. The shell suppresses rate BP more efficiently than previously reported systems. We present first time simple kinetic model...
Abstract Nanocomposites of layered MoS 2 and multi‐walled carbon nanotubes (CNTs) with core–shell structure were prepared by a simple solvothermal method.

Graphene oxide (GO), with its exceptional physical and chemical properties biocompatibility, holds a tremendous potential for sensing applications. In this study, GO, acting both as the electron-transfer bridge signal reporter, was attached on interface to develop label-free electrochemical nanosandwich device detection of interleukin-6 (IL-6). First, single layer GO covalently modified gold electrodes, followed by attachment anti-IL-6 capture antibody form interface. The 4-aminophenyl...
Cooperite, or platinum sulfide (PtS), is a rare mineral that generally exists as microscale, irregularly shaped crystallites. The presence of impurities, in both naturally occurring and synthesized samples, has hindered the study its optical properties past. In this work, we prepare large-scale, uniform PtS films bulk to two-dimensional form through thermally assisted conversion method. An abnormal trend observed linear spectral studies whereby bandgap narrows film thickness decreases. A...

Ternary copolymerization has been proven to be an effective method regulate the photovoltaic properties of polymer donors. However, terpolymers synthesized using ternary strategy inevitably disrupt periodic sequence distribution backbone, resulting in increased molecular disorder and heightened main-chain entropy. Herein, we developed two terpolymer donors by introducing electron-deficient fused-ring skeleton unit BTP with a large dipole moment into main chain PM6 via copolymerization. We...
