Summary: Investigation on the basic properties and dielectric behavior of Bi2S3 nanorods reveals that well-oriented nanorods exhibit high dielectric constant and low dielectric loss. Bi2S3 nanorods with good crystallinity and polycrystalline nature have been synthesized using a forced condensation method. The dispersion of relaxation time at higher temperature was analyzed through the cole-cole analysis.

Summary: A 3D flower-like MoS2/Bi2S3 heterojunction was synthesized successfully, showing enhanced photocatalytic activity and electrochemical performance. The effective separation of charge carriers between Bi2S3 and MoS2 contributes to the improved photocatalytic activity, while the heterojunction exhibits significantly higher capacitance as a supercapacitor electrode compared to pure Bi2S3. The findings suggest a promising potential for metal sulfides heterojunction in multifunctional applications.

Summary: Researchers design multifunctional logic gate devices based on self-powered CdTe/SnSe heterojunction photodetectors, overcoming the challenges of unidirectional electrical transport. The combined photovoltaic effect and photothermoelectric effect enable the control of photocurrent polarity, allowing for the implementation of OR, AND, NAND, NOR, and NOT logic gates in a single heterojunction device. These findings highlight the potential of CdTe/SnSe heterojunctions as logic units in next-generation sensing-computing systems.

Summary: The self-assembly of chiral metal nanoclusters into ordered microstructures with enhanced phosphorescence and optical activities was achieved by manipulating Au nanoclusters modified by L-/D-cysteine. The compact aggregation structures were essential for emission enhancement and chirality amplification, with the microflowers exhibiting pH-responsiveness. Additionally, the pH-responsive photoluminescence ON/OFF switch of the microflowers could be utilized for reliable information encryption and decryption.

Summary: Hierarchical structures composed of MoS2 nanosheets grown on Bi2S3 nanorods were prepared via hydrothermal reaction. The innovative heterostructures with distinct porosity and close interfacial contact facilitate effective visible-light utilization and provide permeable routes for reactant molecules to enter the inner structure. The Bi2S3 @MoS2 heterostructure with 50% MoS2 exhibited superior adsorption and photodegradation of Rhodamine B, reaching 97.5%. Toxic heavy metal ions and organic pollutants in water can be eliminated using attractive heterostructures with excellent adsorption capacities and photocatalytic activities.

Summary: The one-step synthesis of Cr2O3/Bi2S3 nanorods with different Cr2O3 contents showed efficient degradation of phenol and methylene blue under visible light irradiation. The 0.04% Cr2O3/Bi2S3 heterostructure exhibited the highest photocatalytic efficiency, indicating an enhanced performance compared to bare Bi2S3 nanorods. The results suggest that the constructed Cr2O3/Bi2S3 heterostructure effectively suppresses carrier recombination and improves photocatalytic efficiency, showing potential for wastewater treatment under sunlight.

Summary: In this paper, the synthesis of high-quality Ta2Ni3Se8 crystals without noble or toxic elements is reported, and photodetectors based on these crystals are fabricated and tested. The results show a broadband photoresponse from 405 nm to 1550 nm, along with relatively high photoresponsivity and specific detectivity, as well as a short response time. The dominant mechanism for photocurrent generation is determined to be the photo-bolometric effect, and the promising applications of Ta2Ni3Se8 in optical communications are highlighted.

Summary: This study prepared two types of microstructures of β-Co(OH)2 electrode materials, nanosheets-assembled microflowers (MFs) and nanowires-based microclews (MCs), through a three-step synthetic method. Both MFs and MCs have huge surface area and may provide abundant electro-active sites. It was found that MFs exhibited higher specific capacity and better rate performance. A hybrid supercapacitor (HSC) device was designed to evaluate the potential of practical applications in SCs, demonstrating the potential of MFs in high-performance HSC devices.

Summary: Taking a solution-based approach to obtain transition metal dichalcogenide monolayers offers several advantages, including scalable processing, cost-effectiveness, and the ability to tune monolayer functionality through solution chemistry. Stacking two-dimensional network films layer-by-layer on different substrates allows control over the chemical nature, shape, and position of each layer, resulting in multilayers with increased electrical conductivity and photoconductivity. The scalability and ease of device fabrication provided by this approach open up a wide range of applications for solution-based 2D materials.
