Uniform, well-defined cadmium sulfide@cadmium selenide core/shell quantum dots (CdS@CdSe QDs) were, for the first time, successfully synthesized by a solvothermal method and chemical bath growth for photoelectrochemical activities. The as-synthesized CdS@CdSe QDs not only exhibit superior self-powered photoresponse behavior and excellent stability under ambient conditions but also display significantly improved current densities and photoresponsivity compared to those of individual CdS QDs or CdSe QDs, mainly due to the built-in electric field, and thus have great potential in the fields of renewable energy and renewable energy consumption for carbon neutrality target achievement.

“…Recently, SnS/2D nanomaterial hybrids in a sandwiched model were also intensively investigated for targeted applications, such as high-performance solar cells, [133][134][135][136] and electronic devices. [137][138][139][140] For instance, in 2018, the facile morphology control of anisotropic SnS was realized via regulated growth kinetics during vapor transport deposition (VTD), and SnS/2D CdS heterostructure-based thin film solar cells were fabricated to study the impact of the SnS morphology.…”

Tin-based binary chalcogenide Sn-X (X ¼ S, Se, Te) compounds have attracted extensive interest in the optical, optoelectronic, catalysis, and flexible systems due to their intriguing performances. [1][2][3][4][5][6][7] The Sn-X (X ¼ S, Se, Te) compounds are typically layered materials and usually have three crystalline phases: hexagonal, monoclinic, and orthorhombic; orthorhombic phase is denoted by chemical formula SnX, and hexagonal and monoclinic phases are labeled as SnX 2 . [8] Until now, SnSe and SnTe compounds have already achieved great progress in many fields, especially for thermoelectronics and ferroelectrics, [9][10][11][12] and many important reviews have been reported on SnSe and SnTe compounds due to their rapid development. [8,[13][14][15][16] For example, in 2020, Chen et al. [14] summarized a comprehensive overview of controlled synthesis, characterization, and thermoelectric performance in SnSe. In 2018, Shi et al. [8] summarized the growth, characterization, and applications (photovoltaics, supercapacitors, rechargeable batteries, phase-change memory devices, and topological insulator) of SnSe. In 2018, Li et al. [15] reviewed the development of SnS, SnSe, and SnTe, mainly focusing on the controllable tuning of the electron and phonon transport as well as the challenges for further optimization and practical applications. Among Sn-X (X ¼ S, Se, Te) compounds, tin monosulfide (SnS) as a typical black phosphorus analogue, has also received intensive scientific attention due to its unique properties, such as inexpensive, sustainable, suitable bandgap between Si (1.12 eV) and GaAs (1.43 eV), [17] high absorption coefficient (10 À4 cm À1 ), [18] strong mechanical properties, and anisotropic optoelectronic, [19][20][21] which are of great value in optoelectronics, catalysis, sensors, and nanomedicines. [7,[22][23][24][25][26][27] In addition, layered SnS with suitable spacing structures hold promising potentials in the field of lithium (Li)-ion batteries and sodium (Na)-ion batteries due to their relatively high electrical conductivity and theoretical capacity. [28][29][30][31][32] However, although popular SnS has achieved great progress in a variety of fields, few comprehensive reviews have hitherto focused on the field of SnS-based nanostructures and their fascinating applications.Inspired by important reviews on SnSe reported by Chen [14] and Li [8] in recent years, we comprehensively summarized the synthesis, characterization, and the latest progress of SnS-based nanostructures, as shown in Figure 1. First, the most commonly employed techniques (hydrothermal, vapor deposition, electrostatic assembly, etc.) for preparing SnS and SnS-based nanostructures are presented in detail with their recent progress. Furthermore, the fundamental properties (crystal structure, electronic band structure, optical property, and Raman spectroscopy) and diverse applications (batteries, solar cells, catalysis, optoelectronics, sensors, ferroelectrics, thermoelectrics, nonlinear properties, and biomedical applicatio...

“…This aids in optimizing the design of components subjected to mechanical stress, ensuring the material's longevity and reliability (Alamri et al, 2021). The continuity equation, a fundamental principle in fluid dynamics and mass transport, is applied to (Ti-Ni) alloys to ensure mass conservation during phase transformations (Voznyia et al, 2020). As (Ti-Ni) undergoes martensitic phase transitions, mass redistribution occurs.…”

This study investigates the structural mechanics of titanium-nickel (Ti-Ni) alloy thin film using computational modelling through COMSOL Multiphysics based on Poisson’s equation and continuity equation for stress check by considering its linear elastic, conservation of charge and providing insight into nanomaterial deformation. In the COMSOL environment the parameters for titanium nickel (Ti-Ni) are embedded in the COMSOL Simulink interface. The Thin film layer was designed by defining the layer geometry of the size and shape of the layer with a width of 500 μm, depth of 200 μm and height of 3 μm subjected to boundary conditions such as von – mises stress, surface temperature, iso-surface temperature, multi-slice electric potential, displacement component, surface elastic strain energy density and total enthalpy. The results displayed a trend that is, as the surface temperature increases there will be an increase in the current densities associated with high electrical conduction. On the same note, the designed thin film layer will pass the percolation threshold. The results of surface elastic strain energy density and total enthalpy imply that the designed thin film layer is effective and efficient as a structural pseudopotential device (photodiode).
