Summary: A series of virgin and lithia-doped Ni ferrites were synthesized using egg-white-mediated combustion, and their properties were characterized using various techniques such as XRD, FTIR, and HRTEM. Lithia doping was found to enhance the structural parameters, magnetic properties, and morphological properties of the ferrites. The presence of nanoscale particles and shape modification were observed in the lithia-doped ferrite. Additionally, an increase in dopant content led to a decrease in magnetization and an increase in coercivity.

Summary: The E3 transition in irradiated GaAs has been observed to have three distinct components in deep level transient spectroscopy (DLTS). The component designated E3c is found to be metastable, reversible bleaching under minority carrier injection, with an introduction rate depending on Si doping density. First-principles modeling reveals that E3c must be the intimate Sivacancy pair, best described as a Si sitting in a divacancy Sivv. The bleached metastable state is enabled by a doubly site-shifting mechanism, where the defect undergoes a second site shift upon recharging rather than returning to its original E3c-active configuration by reversing the first site shift. Identifying this defect provides insights into short-time annealing kinetics in irradiated GaAs.

Summary: A polyol solvothermal method is developed to synthesize LiMn0.7Fe0.3PO4, which can simultaneously increase particle size (decrease specific surface area) and regulate crystal orientation (improve kinetics) to enhance lithium ion diffusion kinetics. Cobalt doping and carbon coating further improve the kinetic properties. Electrochemical measurements show increased Li+ diffusion kinetics for the Fe2+/3+ and Mn2+/3+ redox couple during charging and discharging, respectively. The material exhibits a capacity of 150 mAh g-1 at a 5C rate, and in full batteries, it retains 89.6% capacity over 1000 cycles at a 1C rate.

Summary: The electronic structure and magnetic properties of Li(ZnMn)As with antisite defects were investigated using first-principles calculations. The cation antisite defect induced by Zn substitution for As was considered. The formation of d-sp hybrid orbitals involving Mn-3d, As-4p, Zn-4s, and Zn-4p enhanced the non-localized properties of Mn-3d electrons and provided a channel for indirect exchange of electrons between the magnetic ions. The antisite defect of Zn-substituted As acted as an acceptor doping, resulting in p-type characteristics and regulating the magnetic ordering transition. The ferromagnetic coupling between the Mn magnetic dopants was favored in the system with an antisite defect. This study designed a novel type of dilute magnetic semiconductor with controllable carriers and revealed the mechanism of ferromagnetic coupling, providing a theoretical reference for future studies.

Summary: Sublattice distortion resulting from alloying compositionally distinct double perovskites affects the photoluminescence emission, mainly through the formation and recombination of self-trapped excitons (STE). The intensity and quantum yield of STE emission depend on the alloy composition, with the highest intensity observed at a specific composition due to a large change in sublattice distortion. The variation in photoluminescence properties follows a similar trend as that of bandgap and phonon vibrational changes caused by sublattice distortion.

Summary: Whispering gallery mode (WGM) lasing is achieved in CsPbI3 quantum dots (QDs) coated on TiO2 spherical microcavities. The photoluminescence emission from the CsPbI3-QDs gain medium strongly couples with the TiO2 microspherical resonating optical cavity. Above a threshold point of 708.7 W/cm2, spontaneous emission in the microcavities switches to stimulated emission, resulting in increased lasing intensity as the power density increases.

Summary: In this study, comprehensive vibrational studies using micro-Raman spectroscopy were conducted to investigate the influence of octahedral cation substitution on lattice vibrations in metal halide double perovskites. It was found that Na+ substitution enhanced the F-2g mode intensity and improved cationic ordering. The symmetric stretching A(1g) mode was mainly influenced by the octahedral cations, while the appearance of distinct octahedral modes can be attributed to B ''-site substitution. The presence of asymmetric-stretching vibrations (E-g) indicated sublattice distortions in the lattice.

Summary: Sb1.9Al0.1S3 nanorods with constrained cutoff voltage in the alloying regime exhibit excellent electrochemical performance, providing an initial capacity of around 450 mA h g(-1) and showing excellent cycling stability with 63% retention (around 240 mA h g(-1) after 1000 cycles at 5C-rate) compared to 71.4 mA h g(-1) after 500 cycles observed in full-regime cycling. The formation of crystalline Sb(Al) in Sb1.9Al0.1S3 and the retention of nanorod microstructure enhance its performance, while Sb2S3 nanorod electrodes get pulverized and show microcracks. Percolating Sb nanoparticles buffered by the Li2S matrix and other polysulfides contribute to the improved performance of the electrode. These findings pave the way for high-energy and high-power density LIBs with alloy anodes.

Summary: Anionic alloying in lead-free halide double perovskites is an effective strategy to tailor their optoelectronic properties. However, it has been found that halide ions do not mix uniformly at the atomic scale and tend to form octahedral structures rich in a particular halogen. This preferential occupation of halide ions in the alloyed structure is more stable compared to local phase segregation or homogeneous mixing. The variation in the band gap is primarily correlated to the concentration of Cl and Br anions rather than their distribution in individual octahedra.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
