The synergistic effect of a single atom of Fe and heteroatom in X-doped Mo 2 CS 2 –MXene (X = B, N, O, F, P and Se) in enhancing the electrocatalytic reduction of nitrogen to ammonia. , Conversion of nitrogen (N 2 ) to ammonia (NH 3 ) is a significant process that occurs in environment and in the field of chemistry, but the traditional NH 3 synthesis method requires high energy and pollutes the environment. In this work, the charge, orbital and spin order of the single-atom Fe loaded on heteroatom (X) doped-Mo 2 CS 2 (X = B, N, O, F, P and Se) and its synergistic effect on electrochemical nitrogen reduction reaction (eNRR) were investigated using well-defined density functional theory (DFT) calculations. Results revealed that the X-element modified the charge loss capability of Fe atoms and thereby introduced a net spin through heteroatom doping, resulting in the magnetic moment modulation of Fe. Upon incorporating N 2 molecule vertically into Fe@P-doped-Mo 2 CS 2 , the strongest eNRR performance and activation ability for the NN were achieved. This was due to the 1π u antibonding orbitals being filled with extra charges from Fe atoms and the σ 2s bonding orbitals experiencing a splitting phenomenon as a result of net spin injection from P atoms. Thus, this work provides rational design principles for the development of non-noble metal eNRR electrocatalysts by ingeniously manipulating their spin order and local environments.

            The correlation between the glass‐forming ability (GFA) of Metal–Organic Frameworks (MOFs) and their structural characteristics remains poorly understood. To address this gap, we analyze over 20,000 MOFs from the MOF database, comparing geometric and electronic order parameters between zeolitic imidazolate frameworks (ZIFs) and other MOFs. Our findings reveal a set of order parameters that effectively capture the thermal stability, and GFA of MOFs, acting as structural genes to predict glass formation. Through molecular dynamics simulations on representative ZIFs structures, we validate the reliability of these order parameters, particularly the total bond‐order density (TBOD) and the largest cavity diameter (LCD), for screening potential melt‐quenched MOFs. Furthermore, we predict that external pressure and electric fields can control the TBOD of MOFs, expanding our understanding of their thermal stability. This work identifies structural genes associated with the melt stability of MOFs, and contributes valuable insights into the prediction and understanding of MOFs glass‐forming ability.},

Abstract The correlation between the glass‐forming ability (GFA) of Metal–Organic Frameworks (MOFs) and their structural characteristics remains poorly understood. To address this gap, we analyze over 20,000 MOFs from the MOF database, comparing geometric and electronic order parameters between zeolitic imidazolate frameworks (ZIFs) and other MOFs. Our findings reveal a set of order parameters that effectively capture the thermal stability, and GFA of MOFs, acting as structural genes to predict glass formation. Through molecular dynamics simulations on representative ZIFs structures, we validate the reliability of these order parameters, particularly the total bond‐order density (TBOD) and the largest cavity diameter (LCD), for screening potential melt‐quenched MOFs. Furthermore, we predict that external pressure and electric fields can control the TBOD of MOFs, expanding our understanding of their thermal stability. This work identifies structural genes associated with the melt stability of MOFs, and contributes valuable insights into the prediction and understanding of MOFs glass‐forming ability.

Abstract The intricate competition between seed formation and the growth-limited area in 2D transition metal dichalcogenides has long hindered their potential applications. This study investigated the morphological and photophysical characteristics of few-layer tungsten disulfide (FL-WS 2 ) thin films deposited on SiO 2 /Si substrates via pulsed laser deposition (PLD). To induce morphological changes, the number of laser pulses was varied (50, 150, and 300 shots), followed by a post-deposition annealing treatment. Atomic force microscopy (AFM) demonstrated three distinct morphological features: continuous films, particulates, and islands, indicative of a growth evolution consistent with the Stranski–Krastanov (layer-plus-island) mechanism. X-ray photoelectron spectroscopy (XPS) revealed the presence of a semiconducting phase of 2H-WS 2 and sulphur-deficient species (WS x ) in the films. While Raman modes characteristic of WS 2 were observed, the absence of photoluminescence (PL) emission suggested the presence of defect states in the as-grown thin films. Upon post-annealing treatment, we observed a reduction in WS x species (150 and 300 laser shots) accompanied by a reduction of particulate density. This, in turn, triggers a defect state suppression, by which the PL spectra of all samples emerge, unveiling the near-resonance emission and excitonic features. This observation was confirmed by the density functional theory (DFT) simulation, pointing to the presence of an extra energy level around the K point of the Brillouin zone at high concentration of sulphur vacancy, which corresponds to the splitting of near-resonant PL emission. In addition, two pronounced Raman modes at 264 cm −1 and 334 cm −1 are associated with structural relaxation due to post-annealing. This relationship between morphological characteristics and emissive behaviour of large-area FL-WS 2 thin films provides valuable insights into their photophysical modulation, paving the way for advanced photonic applications.

          , 
            
              The controllable doping of hybrid organic–inorganic perovskites (HOIPs) has fueled strong interest in their utilization as scintillating materials. In terms of cation engineering, tin mixed-halide perovskites (TMHPs) are considered a stronger contender than their conventional hybrid perovskite counterparts. However, their inability to undergo physicochemical alteration
              via
              simultaneous A-site and X-site substitution remains unresolved to date. In this work, we tailor the organic ligand and halide mixture of TMHPs to shed some light on their optical and scintillation properties. By introducing three organic ligands, we synthesize phenylmethylammonium (PMA), phenethylammonium (PEA) and phenylpropylammonium (PPA) and retain the Br : I ratio at 3 : 1. In terms of structural order, we show that the interlayer spacing between the inorganic layers is gradually extended from 9.88 Å for (PMA)

The controllable doping of hybrid organic–inorganic perovskites fueled strong interest as scintillating materials. , The controllable doping of hybrid organic–inorganic perovskites (HOIPs) has fueled strong interest in their utilization as scintillating materials. In terms of cation engineering, tin mixed-halide perovskites (TMHPs) are considered a stronger contender than their conventional hybrid perovskite counterparts. However, their inability to undergo physicochemical alteration via simultaneous A-site and X-site substitution remains unresolved to date. In this work, we tailor the organic ligand and halide mixture of TMHPs to shed some light on their optical and scintillation properties. By introducing three organic ligands, we synthesize phenylmethylammonium (PMA), phenethylammonium (PEA) and phenylpropylammonium (PPA) and retain the Br : I ratio at 3 : 1. In terms of structural order, we show that the interlayer spacing between the inorganic layers is gradually extended from 9.88 Å for (PMA) 2 SnBr 3 I and 10.29 Å (PEA) 2 SnBr 3 I to 10.06 Å for (PPA) 2 SnBr 3 I. Based on geometrical order, organic chain penetration and octahedral distortion angles, we propose a rational design to modulate the absorption, photoluminescence (PL), optical bandgap, and thermal quenching of TMHPs. (PMA) 2 SnBr 3 I exhibits the fastest decay time ( τ avg = 1.1 ns) compared to (PEA) 2 SnBr 3 I ( τ avg = 2.51 ns) and (PPA) 2 SnBr 3 I ( τ avg = 3.54 ns), indicating that TMHPs are promising candidates for scintillator applications. This finding is corroborated by density functional theory, which outlines the weakened antibonding interaction between I 5p and Sn 5s orbitals upon tailoring the organic ligand of the perovskite. Our results demonstrate the importance of cation engineering in leveraging innovative hybrid perovskites with novel responses via a rational design.

It is found that the wall material has a special structure of interwoven needle‐like crystals as a way to provide high flexural strength. The main composition of 34.94% phosphate tailings, 36.75% calcined phosphate tailings, 16.64% silica fume, 6.67% anhydrous magnesium sulfate is required to achieve an optimal maintenance process for 4 h of heat preservation at 120 °C saturated vapor pressure environment.

Abstract Zirconium carbide (ZrC) and hafnium carbide (HfC) have been identified as ultrahigh temperature ceramics with excellent thermal conductivity performance. The temperature profiles of ZrC and HfC have been studied; however, the temperature‐dependent of solid solution of (Zr 0.5 Hf 0.5 )C is still lacking. Herein, we report the temperature‐dependent elastic and thermodynamic properties of (Zr 0.5 Hf 0.5 )C using first‐principles calculations. The covalent characters of ZrC, HfC, and (Zr 0.5 Hf 0.5 )C are weakened at high temperatures by analyzing their respective electronic structures. In addition, the equilibrium volumes at different temperatures can be determined from the energy–volume ( E – V ) curves under the quasi‐harmonic approximation. Throughout the temperature ranges studied, the HfC material shows the highest bulk modulus and lowest thermal expansion. When T  \textgreater 1000 K, (Zr 0.5 Hf 0.5 )C exhibits better shear and Young's modulus performance close to HfC and shows the highest anisotropy. The lattice thermal conductivity decreased as temperature increased for ZrC, HfC, and (Zr 0.5 Hf 0.5 )C, and (Zr 0.5 Hf 0.5 )C has the smallest lattice thermal conductivity. These results provide fundamental and useful information for the practical application of ZrC, HfC, and (Zr 0.5 Hf 0.5 )C.

Abstract There are works have reported the crystal structures and mechanical properties of ferrite cement (C 4 AF) at the atomic scale with deviation owing to the omission of the Coulomb interaction effect ( U eff ) between 3 d electrons of Fe in C 4 AF. In this work, the DFT+ U method was used to evaluate its effect on their electronic structures and mechanical properties of C 4 AF with two different phases I2mb (C 4 AF‐ I ) and Pnma (C 4 AF‐ P ). The FeO bonds of the two phases are all weaker and display U eff due to the presence of Fe ions. The mechanical properties of C 4 AF calculated using DFT+ U method significantly differ from those obtained without considering U eff , in which the former shows lower inferior mechanical properties than the latter. This work presents a comparative study the effect of Coulomb interaction to the internal electronic structures and mechanical properties, which will pave the way for designing high hydration reaction cement and high toughness materials.

2D PtTe 2 films only form below 300 °C and prefer a bilayer growth mode. The bandgap is 0.80 eV for the monolayer and 0 eV for layer numbers ≥2. , 2D platinum ditelluride (PtTe 2 ) has received significant attention for 2D photodetector applications due to its novel physical properties. One of the critical factors that affect device performance is the film quality. Here, using molecular beam epitaxy, we investigate the role of growth temperature in determining the film quality of PtTe 2 on highly oriented pyrolytic graphite, and unveil its layer-dependent electronic properties by X-ray photoelectron spectroscopy, Raman spectroscopy, and scanning tunneling microscopy/spectroscopy (STM/STS), as well as density functional theory (DFT) calculations. At low growth temperature (≤250 °C), the PtTe 2 film prefers a stack of the monolayer and bilayer, while at ≈300 °C large-area continuous bilayer films are formed. In contrast, high growth temperature (\textgreater300 °C) leads to the formation of thick films with high Te deficiency and poor crystallinity. Theoretical calculations confirm the higher thermal stability of bilayer PtTe 2 over other layer numbers above a critical crystal size of ≈100 nm 2 . STS shows that PtTe 2 is a semiconductor in the monolayer with a bandgap of 0.80 ± 0.05 eV, and changes to a semimetal from the bilayer. DFT calculations support our experimental results and suggest an indirect bandgap structure of the monolayer. This work provides a systematic study of the layer-dependent electronic structure of 2D PtTe 2 , and demonstrates that with appropriate substrate and growth temperature choices, high-quality ultrathin PtTe 2 films can be obtained, important for device applications.
