Theoretical design of two-dimensional AMInP₂X₃Y₃ (AM = Li, Na, K; X/Y = S, Se, Te) monolayers for highly efficient excitonic solar cells

Abstract

Two-dimensional alkali metal indium phosphorus trichalcogenides AMInP2X3Y3 monolayers are regarded as promising candidates for use in photovoltaic solar cells.

Multimodal Engineering of Catalytic Interfaces Confers Multi‐Site Metal‐Organic Framework for Internal Preconcentration and Accelerating Redox Kinetics in Lithium‐Sulfur Batteries

“…As illustrated in Figure 4e, the MSC‐MOF‐Ti interlayer‐enabled pouch cell served as a mobile phone charger and maintained stability for over 60 cycles at 0.1 C. Furthermore, a multiple‐layer pouch cell achieving a high gravimetric energy density of 350.8 Wh kg −1 was successfully demonstrated (Figure 4f, S26 and Table S1). All these results collectively demonstrate the efficacy of molecular‐level design of adsorption/catalysis interfaces in a multi‐site MOF‐based interlayer for the effective preconcentration and catalysis of polysulfides, as well as the suppression of the shuttle effect in high‐energy density LSBs [23] . These results are highly competitive compared with previously reported LSBs assembled with catalytic MOFs (Figure 4g).…”

Co3O4/RGO Nanoparticles Fabricated by Facile Solvothermal Method as an Anode Material for High‐Performance Lithium‐Ion Batteries

“…Figure 3a shows the survey XPS spectrum; we can see that there are the Co 2p and O 1s peaks, proving the composition elements on the surface of Co 3 O 4 materials. The spectrum of Co 2p is presented in the Figure 3b, two peaks at 774.98 and 780.08 eV, respectively, correspond to Co 2p 1/2 and Co 2p 3/2 with a spin‐orbit splitting of 15.1 eV [31] . The Co 2p 1/2 and Co 2p 2/3 peaks can be divided into two parts, and the core energy levels of 796.4, 781.3 eV, and 794.9, 779.9 eV are corresponded to Co 2+ and Co 3+ ions, respectively, which are typical feature of Co 3 O 4.…”

Expanding the Horizons of Machine Learning in Nanomaterials to Chiral Nanostructures

“…These and other properties make chiral NMs an important area of study. For interested readers, more detailed information on chirality and chiral NMs can be found in the cited reviews, [24,190,207,[212][213][214] including more specific topics, such as plasmonic particles, [215][216][217][218][219] carbon dots, [220] magnetic NMs, [221] perovskites, [222,223] quantum dots, [26] chiral assemblies, [216,218,[224][225][226] CPL emitters, [214,221,224,227,228] biological applications, [23,191,217,229,230] catalysis, [231,232] chiral spectroscopy, [221] and intrinsic chirality. [28] Since the main application of ML in nanotechnology, including the field of chiral NMs, is the analysis of synthesis-structureproperty-application relationships, it is necessary to briefly discuss relevant aspects of chiral NMs.…”
