Dual-Gate Modulation in a Quantum Dots/MoS Thin-Film Transistor Gas Sensor.

Mastering the surface chemistry of quantum dots (QDs) has enabled a remarkable gas-sensing response as well as impressive air stability. To overcome the intrinsic receptor-transducer mismatch of QDs, PbS QDs used as sensitive NO receptors are spin-coated on top of a few-layer MoS and incorporated into a thin-film transistor (TFT) gas sensor. This architecture enables the separation of the electron transduction function from the chemical reception function.

Use of traditional Chinese medicine bezoars and bezoar-containing preparations in hepatocarcinoma.

This manuscript used network pharmacology and experimental verification to analyze the anti-hepatocarcinoma mechanism of action of bezoars in traditional Chinese medicine (TCM), discovering that it can affect the immune cells within the tumor microenvironment and related pathways to produce inhibitory effects in liver cancer. In TCM, bezoars have a unique therapeutic advantage in the prevention and treatment of tumors. They play an anti-tumorigenic role by regulating the immune microenvironment through multi-component, multi-target and multi-pathway mechanisms.

Circularly polarized light emission and detection by chiral inorganic semiconductors.

Chiral inorganic semiconductors with high dissymmetric factor are highly desirable, but it is generally difficult to induce chiral structure in inorganic semiconductors because of their structure rigidity and symmetry. In this study, we introduced chiral ZnO film as hard template to transfer chirality to CsPbBr film and PbS quantum dots (QDs) for circularly polarized light (CPL) emission and detection, respectively. The prepared CsPbBr/ZnO thin film exhibited CPL emission at 520 nm and the PbS QDs/ZnO film realized CPL detection at 780 nm, featuring high dissymmetric factor up to around 0.

Probing the interlayer excitation dynamics in WS/WSe heterostructures with broadly tunable pump and probe energies.

van der Waals heterostructures based on transition metal dichalcogenides (TMDs) provide a fascinating platform for exploring new physical phenomena and novel optoelectronic functionalities. Revealing the energy-dependence of photocarrier population dynamics in heterostructures is key for developing optoelectronic or valleytronic devices. Here, the broadband transient dynamics of interlayer excitation of a nearly-aligned WS/WSe heterostructure is investigated by using energy-dependent pump-probe spectroscopy at cryogenic temperatures.

Traditional Chinese Medicine for Breast Cancer: A Review.

A total of 18% of global breast cancer (BC) deaths are attributed to BC in China, making it one of the five most common cancers there. There has been a steady rise in BC morbidity and mortality in women in the last few years and it is now a leading cancer among Chinese women. Conventional treatments for BC are currently effective but have several limitations and disadvantages, and Traditional Chinese medicine (TCM) plays a vital role in the overall process of cancer prevention and therapy.

CS-NO is a polysaccharide-based biomaterial with NO-releasing properties that shows promising therapeutic potential.

Room-temperature unidirectional routing of valley excitons of monolayer WSe via plasmonic near-field interference in symmetric nano-slits.

Due to the short valley polarization time, it is hardly to separate opposite valley pseudospin of transition metal dichalcogenides (TMDs) for their practical applications in valleytronics. Coupling TMDs to unidirectional surface plasmon polariton (SPP) can overcome this obstacle. However, it is required to break the symmetry to induce the asymmetric coupling between valley exciton dipole and SPP to route valley exciton in previously proposed strategies.

All-Optical Valley Polarization Switch via Controlling Spin-Triplet and Spin-Singlet Interlayer Exciton Emission in WS/WSe Heterostructure.

Although selective singlet and triplet interlayer exciton (IX) emission of transition metal dichalcogenides (TMD) heterostructures can be achieved by applying an electric or magnetic field, the device structure is complex and a low temperature is usually required. Here, we demonstrate a simple all-optical approach to selectively enhance the emission of singlet and triplet IX by selectively coupling singlet or triplet IX of a WS/WSe heterostructure to a SiO microsphere cavity. Angle-resolved photoluminescene reveals that the transition dipole of triplet IX is almost along the out-of-plane direction, while singlet IX only has 69% out-of-plane dipole moment contribution.

Layer-Number Engineered Momentum-Indirect Interlayer Excitons with Large Spectral Tunability.

Interlayer excitons (IXs) in type II van der Waals (vdW) heterostructures are equipped with an oriented permanent dipole moment and long lifetime and thus would allow promising applications in excitonic and optoelectronic devices. However, based on the widely studied heterostructures of transition-metal dichalcogenides (TMDs), IX emission is greatly influenced by the lattice mismatch and geometric misalignment between the constituent layers, increasing the complexity of the device fabrication. Here, we report on the robust momentum-indirect IX emission in TMD/two-dimensional (2D) perovskite vdW heterostructures, which were fabricated without considering the orientation arrangement or momentum mismatch.
