Extremely Reduced Dielectric Constant and Band Gap Enhancement in Few-Layered Tungsten Disulfide Nanosheets

“…Recently, two-dimensional (2D) materials such as graphene and inorganic graphene analogue, i.e., transition metal dichalcogenides (TMDCs) of type MX 2 (M = Mo or W and X = S, Se, or Te), have triggered an extensive interest due to their intriguing physical, thermal, and chemical properties. − Unlike graphene, which consists of a single carbon atomically thick layer, the TMDCs, such as WS 2 , MoS 2 , and WSe 2 , have a “sandwich” type structure where a transition metal layer (e.g., Mo or W) is arranged in a sandwiched structure between two chalcogen layers (e.g., S, Se, or Te) . Recently, various 2D materials such as MXene, graphene, and MoS 2 have been used as electromagnetic absorber, and they have been successfully utilized to fabricate wearable, hydrophobic, and EMI shielding devices. − Graphene-based flexible multifunctional microsensors based on electromagnetic response and plasma resonance have also been reported. , The dielectric and optical properties of 2D functional materials have been also used to design lightweight nanoscale electromagnetic devices with high efficiency. − The performance of the EM shielding of the flexible devices strongly depends on the UV absorption, band gap, and dielectric polarizability of the 2D materials under various frequency ranges. , Therefore, investigation of the optical and dielectric properties of the 2D materials such as WS 2 nanosheets is crucial to fabricate next-generation electronic devices …”

Green synthesis of Mesona Blumes gum capped silver nanoparticles and their antioxidant, antibacterial and catalytic studies

“…The synthesized MB@AgNPs were monitored with a UV-visible absorption spectrophotometer by evaluating the changes in solution colour. 26 Microwave irradiation of the Ag + ion solution results in a change in colour from colourless to yellowish orange. AgNPs are formed by the reduction of Ag + to Ag 0 .…”

Post‐Graphene 2D Materials: Structures, Properties, and Cancer Therapy Applications

“…[30,31] In addition, studies have shown that compared with graphene oxide and halogenated graphene, MoS 2 and WS 2 are less harmful, while WSe 2 has comparable cytotoxicity. [32][33][34] Even at high concentrations, MoS 2 and WS 2 still show high compatibility with A549 cells, while WSe 2 shows a dose-dependent toxicological effect on A549 cells. [29] Overall, MoS 2 and WS 2 are a promising medical nanomaterial compared with other similar TMDs.…”
