Summary: Nickel-cobalt carbonate hydroxides are widely used as battery-type electrode materials, but their electrochemical performance still needs improvement. Most studies have focused on compounding with conductive carbon materials or changing the nanostructure of the material by adjusting the Ni/Co ratio. However, these methods require binder and complicated operation, respectively. In this study, an in-situ isomorphous recombination method was proposed to improve the performance of basic nickel-cobalt carbonate. The synthesized composite electrode exhibited a large specific capacity and good cycling stability.

Summary: Co3(PO4)2/Ag3PO4 (CoPi/AgP) was immobilized onto SiC nanowires through co-precipitation. The photoactivity and photostability of CoPi/AgP/SiC were significantly enhanced compared to Ag3PO4, while reducing the cost due to the low demand for expensive Ag3PO4. Under visible light, Ag3PO4/SiC loaded with 0.5%Co3(PO4)2 achieved a higher degradation rate of methyl orange (MO) compared to Ag3PO4 and Ag3PO4/SiC. The synergistic action of the Z-scheme Ag3PO4/SiC heterojunction and Co3(PO4)2 cocatalyst led to enhanced photoactivity and stability.

Summary: The development of a heterojunction nanocomposite has improved optoelectronic properties. In this study, cerium oxide (CeO2), copper oxide (CuO), and ceria-copper-copper hydroxide (CeO2-CuO-Cu(OH)(2)) nanocomposites were prepared and their structural, morphological, and optical properties were investigated. The integration of CeO2 and CuO with Cu(OH)(2) modified the band gap, leading to improved photocatalytic efficiency. CeO2 enhanced light absorption, while CuO acted as an electron trap in the composite, resulting in enhanced optical properties. The heterojunction combination in the nanocomposite facilitated charge separation and increased charge participation in catalyzed conversion reactions. The highest photocatalytic degradation efficiencies were achieved using the CeO2-CuO-Cu(OH)(2) nanocomposite for fast green (96.4%) and bromophenol blue (92.7%).

Summary: By using a 100 mM xylitol additive, the plating/stripping processes in Zn-ion batteries can achieve high reversibility. The xylitol molecules not only inhibit the hydrogen evolution reaction, but also accelerate the migration of cations through the expelling of active H2O molecules and weakening of electrostatic interactions. Additionally, the preferential adsorption of xylitol molecules on the Zn surface forms a shielding buffer layer, which hinders the sedimentation and diffusion of Zn2+ ions.

Summary: In this work, Fe-doped flower-like In2S3/Fe3S4 hetero-microspheres (Fe-In2S3/Fe3S4 HMSs) were prepared through a facile one-pot solvothermal reaction and demonstrated as efficient S-scheme photocatalysts for visible-light-driven CO2 photoreduction. The doping of Fe reduced the bandgap of In2S3, extended the optical response to the visible-light region, increased the densities of donors and sulfur vacancies, and elevated the Fermi level. The enhanced interfacial electric field resulted in promoted carrier transfer in the S-scheme pathway. Fe-doped In2S3 also reduced the formation energy of the *CO intermediate, which favored the CO evolution at the surface.

Summary: Raman spectra were used to study the strain's effect on phonon modes in InAs/AlAs short-period superlattices, considering confinement effect and interface mode. The strain in the InAs layer varied significantly at different growth temperatures while strain in the AlAs layer remained constant. Confinement effect was found to be stronger in shorter periods and higher interface quality superlattices, affecting optical phonons. Interface phonon modes were resolved for thickness estimation, and disorder-activated acoustic phonon modes were discussed.

Summary: The Fano line shape at around 185 cm(-1) is observed in temperature-dependent Raman spectra of BaTiO3 nanoparticles. The dip structure on the low-energy side indicates a positive asymmetric parameter q, which is attributed to the interference between the central peak from quasi-elastic scattering mode and the A(TO) vibrational mode around 180 cm(-1). Furthermore, the relationship between the phase change of BaTiO3 nanoparticles and the Fano line shape is discussed. This work deepens the understanding of the mechanism underlying the Fano line shape in Raman spectra and provides a powerful strategy to characterize the phase change of nanostructured BaTiO3.

Summary: In this study, spectroscopic ellipsometry (SE) was used to investigate the optical properties of (InAs)n/(AlAs)n short-period superlattices (SPS) with different period thicknesses in a wide wavelength range. Additionally, (InAs)2/(AlAs)2 samples grown at different temperatures were also examined. The dielectric functions were extracted and Adachi's model was adapted to determine the interband transition energies. The results showed that the quantum confinement effect and strain effect led to a decrease in the transition energies with increasing period thickness. Moreover, as the growth temperature increased, all the transition energies decreased due to the enhanced lateral composition modulation and relaxation of compressive strain in InAs layers.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
