The precise precursor supply is a precondition for controllable growth of two-dimensional (2D) transition metal dichalcogenides (TMDs). Although great efforts have been devoted to modulating the supply, few effective methods chalcogen feeding control were developed. Here we report strategy using active monomer grow high-quality TMDs in robust and manner, e.g., MoS2 monolayers perform representative photoluminescent circular helicity ~92% electronic mobility ~42 cm2V-1s-1. Meanwhile, uniform...
One-dimensional transition metal dichalcogenides exhibiting an enhanced bulk photovoltaic effect have the potential to exceed Shockley–Queisser limit efficiency in solar energy harvest within p - n junction architectures. However, collective output of these prototype devices remains a challenge. We report on synthesis single-crystalline WS 2 ribbon arrays with defined chirality and coherent polarity through atomic manufacturing strategy. The was by substrate couplings into tunable armchair,...
The modulation of optical harmonic generation in two-dimensional (2D) materials is paramount importance nanophotonic and nano-optoelectronic devices for their applications switching communication. However, an effective route with ultrafast speed, ultrahigh depth, broad operation wavelength range awaiting a full exploration. Here, we report that pump can dynamically modulate the third (THG) graphene monolayer relative depth above 90% at time scale 2.5 ps frequency ranging from near-infrared...
In van der Waals (vdW) heterostructures, the interlayer electron-phonon coupling (EPC) provides one unique channel to nonlocally engineer these elementary particles. However, limited by stringent occurrence conditions, efficient engineering of EPC remains elusive. Here we report a multitier in WS2/boron nitride (BN) including isotope enrichments BN substrates, temperature, and high-pressure tuning. The hyperfine dependence Raman intensities was unambiguously revealed. combination with...
In this work, the crystallization process of selenium was accelerated by ultrasonic wave. The effects waves and conventional conditions were compared to understand different on crystallization, including time, power, reduction temperature, H2SeO3 concentration. mechanism ultrasound affecting also investigated scanning electron microscopy (SEM) transmission (TEM). experimental results showed that temperature significantly influenced morphology selenium. Ultrasonic time had a large effect...
To realize the classification of lubricating oil types using mid-infrared (MIR) spectroscopy, linear discriminant analysis (LDA) was used for dimensionality reduction spectrum data, and model established based on support vector machine (SVM). The spectra samples were pre-processed by interval selection, Savitzky–Golay smoothing, multiple scattering correction, normalization. Kennard–Stone algorithm (K/S) to construct calibration validation sets. percentage correct (%CC) evaluate model. This...
Microfloccules of TiO2 nanoparticles, on which glycerol-dehydrogenase (GDH), 1,3-propanediol-oxidoreductase (PDOR), and glycerol-dehydratase (GDHt) were coimmobilized, prepared by adsorption-flocculation with polyacrylamide (PAM).

Abstract Supercontinuum generation (SCG) from silica‐based photonic crystal fibers (PCFs) is of highly technological significance microscopy to metrology, but has been hindered by silica's relatively low intrinsic optical nonlinearity. The prevailing approaches filling PCF with nonlinear gases or liquids can endow fibre enhanced nonlinearity and boosted SCG efficiency, yet these hybrids are easily plagued fusion complexity, environmental incompatibility transmission mode instability.
